Ultrasonic separation device for solution
[0001]
The present invention relates to an ultrasonic separator for a target substance having physical
properties that rapidly migrate to the surface and become excessive on the surface, mainly a
solution for separating alcohol having a higher concentration from an alcohol solution such as
liquor or liquor material.

The present inventor has developed an apparatus for separating an alcohol which is a target
substance exhibiting physical properties that cause surface excess.
(See Patent Document 1) Japanese Patent Application Publication No. 2001-314724
[0003]
This separation device fills an alcohol solution into a closed structure ultrasonic atomization
chamber, and ultrasonically vibrates the alcohol solution in the ultrasonic atomization chamber
with an ultrasonic transducer to atomize it into mist, which is atomized Is collected by
flocculation to separate a high concentration alcohol solution. The separation device can separate
high concentration alcohol as a target substance by the following operation.
[0004]
The alcohol which shows the physical property which transfers to a surface rapidly and becomes
surface excess has the high density ¦ concentration of the surface. When ultrasonic vibration is
performed in this state, the solution on the surface is misted into the air by the energy of the
ultrasonic vibration and is released as fine particles. The mist released into the air has a high
alcohol concentration. This is because the solution on the surface with high alcohol concentration
becomes mist. Therefore, when the mist is collected by aggregation, a high concentration alcohol
solution is separated. This method can separate highly concentrated alcohol solution without
heating the solution. Therefore, the target substance can be separated to a high concentration
with less energy consumption. Moreover, since it does not heat, there also exists a feature which
can be separated without degenerating the target substance.
[0005]
However, in an apparatus for ultrasonically vibrating a solution to separate a target substance, it
is necessary to replace the ultrasonic transducer at regular intervals. This is because when the
lifetime of the ultrasonic transducer is used for a fixed time, the solution can not be ultrasonically
vibrated efficiently. The ultrasonic vibrator is mechanically finely vibrated by the supplied high
04-05-2019

frequency power, so the life is short compared to the electronic component, and ultrasonic
vibration does not occur efficiently after one year. Furthermore, since an ultrasonic transducer
has a relatively small output, it is necessary to use a relatively large number of ultrasonic
transducers in order to separate a target substance from a predetermined amount of solution. In
addition, a device that ultrasonically vibrates the solution with a large number of low-power
ultrasonic transducers can ultrasonically vibrate the solution at many parts of the liquid surface,
so that the solution can be efficiently misted from a wide liquid surface. is there. In order to
realize this, for example, assuming that the total output of the ultrasonic transducer is 1 to
several kW, and the output of one ultrasonic transducer is 10 W, an extremely large number of
100 to several hundreds of ultrasonic transducers are generated. You need to use This device is
extremely laborious to replace the ultrasonic transducer. In particular, since the ultrasonic
transducer fixed on the bottom of the casing of the ultrasonic atomizing chamber is fixed with a
waterproof structure so as not to cause water leakage, it takes more time to replace it. That is
because the packing etc. is sandwiched at the correct position and the ultrasonic transducer is
replaced as a complete waterproof structure.
[0006]

important object of the present invention is to provide an ultrasonic separation device for a
solution which can efficiently and easily exchange a large number of ultrasonic transducers

[0018]
The target substance contained in the above solution has such physical properties that it
transfers to the surface and becomes excessive. Since the target substance has a high surface
concentration, when it is ultrasonically vibrated to atomize the solution on the surface as mist,
the mist has a high concentration of the target substance. Therefore, when the mist is collected
by aggregation, the concentration of the target substance can be increased. That is, it is possible
to separate the solution containing the high concentration target substance.
04-05-2019

[0019]
Hereinafter, an apparatus and a method for separating alcohol at a high concentration from a
solution in which the target substance is alcohol will be shown. However, the present invention
does not specify the target substance as alcohol but can separate all the target substances which
are transferred to the surface and become surface excess.
[0020]
The ultrasonic separation apparatus shown in FIG. 1 and FIG. 2 ultrasonically vibrates the
solution in the ultrasonic atomization chamber 4 with a closed structure to which the solution is
supplied, and atomizes it into mist. The ultrasonic atomizer 1 includes a plurality of ultrasonic
transducers and an ultrasonic power source, and a closed collection chamber 5 that aggregates
and collects the mist atomized by the ultrasonic atomizer 1. The apparatus of FIG. 1 incorporates
the ultrasonic atomization chamber 4 in the recovery chamber 5, and the apparatus of FIG. 2
forms one airtight chamber by the recovery chamber 5 and the ultrasonic atomization chamber
4. And the ultrasonic atomizing chamber 4 are integrally formed. The ultrasonic atomization
chamber 4 and the recovery chamber 5 can be separately disposed, and can be connected by a
duct 26 for transporting the mist.
[0021]
The ultrasonic separation device of FIG. 2 allows the mist of the solution atomized in the
ultrasonic atomization chamber 4 to flow into the collection chamber 5 of the closed structure.
The collection chamber 5 aggregates fine mist and collects it as a high concentration alcohol
solution. Since the mist is not a gas, it can be coagulated and recovered without necessarily
cooling. However, it goes without saying that the mist can be cooled and recovered.
[0022]
The solution is supplied to the ultrasonic atomization chamber 4 by a pump 10. The ultrasonic
atomization chamber 4 does not atomize all the supplied solutions as mist. If all the solutions are
04-05-2019
8
atomized and collected in the collection chamber 5, the concentration of the target substance
such as alcohol in the solution supplied to the ultrasonic atomization chamber 4 and the solution
collected in the collection chamber 5 becomes the same. As the solution supplied to the
ultrasonic atomizing chamber 4 is atomized as mist and the volume decreases, the concentration
of the target substance decreases. For this reason, the target substance concentration of the mist
also decreases gradually. The solution in the ultrasonic atomization chamber 4 needs to be
replaced with a new one when the concentration of the target substance decreases.
[0023]
The ultrasonic atomization chamber 4 atomizes, for example, a solution in which the
concentration of the target substance is 10 to 50% by weight, and after the concentration of the
target substance is decreased, replaces the solution with a new one. After a certain period of
time, the solution is replaced with a new one, that is, the solution is changed batchwise. However,
the stock solution tank 11 storing the solution may be connected to the ultrasonic atomization
chamber 4 via the pump 10, and the solution may be continuously supplied from the stock
solution tank 11. This device supplies the solution from the stock solution tank 11 while
discharging the solution in the ultrasonic atomizing chamber 4 to prevent the concentration of
the target substance such as alcohol in the solution in the ultrasonic atomizing chamber 4 from
decreasing.
[0024]
The solution in the ultrasonic atomization chamber 4 is atomized into mist by the ultrasonic
atomizer 1. The mist atomized by the ultrasonic atomizer 1 has a target substance concentration
higher than that of the solution. Therefore, the device in which the ultrasonic atomizer 1
atomizes the solution into a mist and recovers it can efficiently separate a high concentration
solution.
[0025]
When the solution in the ultrasonic atomizing chamber 4 is ultrasonically vibrated, a solution
having a higher concentration than the solution in the ultrasonic atomizing chamber 4 is
scattered from the liquid surface as a mist. In order to generate mist efficiently, the liquid surface
of the solution is subjected to ultrasonic vibration. In order to realize this, the ultrasonic atomizer
04-05-2019
9
1 shown in FIG. 3 faces the ultrasonic transducer 2 of the ultrasonic atomizer 1 upward at the
bottom of the ultrasonic atomization chamber 4 filled with the solution. It is arranged in The
ultrasonic transducer 2 emits ultrasonic waves upward from the bottom toward the liquid surface
to ultrasonically vibrate the liquid surface.
[0026]
The ultrasonic atomizer 1 shown in the figure includes a plurality of ultrasonic transducers 2 and
an ultrasonic power source 3 for ultrasonically vibrating these ultrasonic transducers 2. The
ultrasonic transducer 2 is fixed to the bottom of the ultrasonic atomization chamber 4 in a
watertight structure. The apparatus in which the plurality of ultrasonic transducers 2
ultrasonically vibrate the solution atomizes the solution into mist more efficiently.
[0027]
The plurality of ultrasonic transducers 2 are fixed to the desorption plate 12 with a waterproof
structure, as shown in FIGS. 4 and 5. As shown in FIG. 6 and FIG. 7, the desorption plate 12 fixing
the plurality of ultrasonic transducers 2 is mounted on the casing 13 of the ultrasonic
atomization chamber 4 so as to be detachable in a waterproof structure. The desorption plate 12
is attached to the casing 13 of the ultrasonic atomizing chamber 4 so that each ultrasonic
transducer 2 ultrasonically vibrates the solution in the ultrasonic atomizing chamber 4.
[0028]
The desorption plate 12 shown in FIGS. 4 and 5 includes a front plate 12A and a back plate 12B.
The front plate 12A and the back plate 12B are stacked to form an ultrasonic transducer between
the front plate 12A and the back plate 12B. 2 is attached by waterproof structure. The surface
plate 12A has a through hole 12a open, and the vibrating surface 2A is positioned in the through
hole 12a to sandwich and fix the ultrasonic transducer 2 between the surface plate 12A and the
back surface plate 12B. The back surface plate 12B is provided with a recess 12b into which the
ultrasonic transducer 2 is inserted, and the ultrasonic transducer 2 is inserted into the recess
12b. The detachable plate 12 of FIG. 4 is provided with a recess 12b in the back surface plate
12B, but a recess may be provided in the surface plate, and the ultrasonic transducer may be
fitted into this recess.

[0029]
In order to make a waterproof structure between the ultrasonic transducer 2 and the surface
plate 12A, a packing 16 is sandwiched between the surface plate 12A and the ultrasonic
transducer 2. The ultrasonic atomizer 1 shown in FIG. 4 has a waterproof structure by
sandwiching a packing 16 also between the ultrasonic transducer 2 and the back surface plate
12B. However, the ultrasonic atomizer does not necessarily have a waterproof structure between
the ultrasonic transducer and the back plate. That is because the desorption plate having a
waterproof structure between the ultrasonic transducer and the surface plate can be fixed to the
lower surface of the casing of the ultrasonic atomizing chamber to prevent the solution of the
ultrasonic atomizing chamber from leaking. . The packing 16 is an O-ring of a rubber-like elastic
body. The O-ring packing 16 is disposed on the opposing surface of the outer peripheral edge of
the vibration surface 2A of the ultrasonic transducer 2 and the surface plate 12A, so that the
space between the vibration surface 2A of the ultrasonic transducer 2 and the surface plate 12A
is As a waterproof structure, it prevents water from leaking during this time. Furthermore, the
outer periphery of the ultrasonic transducer 2 and the back surface plate 12B are connected by a
waterproof structure.
[0030]
The packing 16 is a rubber-like elastic body such as Teflon (registered trademark), silicon,
natural or synthetic rubber. The packing 16 is sandwiched between the ultrasonic transducer 2
and the front plate 12A, and between the ultrasonic transducer 2 and the back plate 12B in a
state of being elastically deformed and crushed. The connecting portion is in a waterproof
structure by closely adhering to the surfaces of the front plate 12A and the back plate 12B
without a gap. However, as the packing 16, it is also possible to use a metal packing obtained by
processing a metal such as copper, sintu, aluminum or stainless steel into a ring shape.
[0031]
The detachable plate 12 shown in FIGS. 4 and 5 connects the one side edges of the front plate
12A and the back plate 12B with hinges 17. As shown in FIG. The desorption plate 12 opens the
back plate 12B and the front plate 12A so that the ultrasonic transducer 2 can be easily
detached. When the ultrasonic transducer 2 is replaced, the back plate 12B and the front plate
12A are opened. In this state, the old ultrasonic transducer is taken out and a new ultrasonic
04-05-2019
11
transducer 2 and packing 16 are put in place. Thereafter, the back plate 12B and the front plate
12A are closed, and the ultrasonic transducer 2 is replaced. The closed back surface plate 12B
and the front surface plate 12A are connected at the opposite side of the hinge 17 with a set
screw (not shown) or fixedly connected to the casing 13 of the ultrasonic atomization chamber 4.
[0032]
Although the above-mentioned ultrasonic atomizer 1 is made into waterproof structure using
packing 16, it can also be filled with caulking material in the position of packing, and can be
made into waterproof structure. Furthermore, although the ultrasonic atomizer 1 shown in FIG. 4
comprises the desorbing plate 12 with two metal plates consisting of a front plate 12A and a
back plate 12B or a nonmetallic hard plate, the desorbing plate 12 One plate may be used as
shown in FIGS. The desorption plate 12 is a metal plate or a nonmetal hard plate, and is provided
with a recess 12b for receiving the ultrasonic transducer 2 open upward.
[0033]
In the ultrasonic atomizer 1 of FIG. 8, the ultrasonic transducer 2 is inserted into the recess 12 b
of the desorption plate 12, and the packings 16 are disposed above and below the outer
peripheral portion of the ultrasonic transducer 2. Further, the ring plate 18 is fixed to the
opening of the desorption plate 12. The ring plate 18 presses the packing 16 disposed on the
upper surface of the ultrasonic transducer 2 to fix the ultrasonic transducer 2 to the recess 12 b
with a waterproof structure. The recess 12 b has a through hole 12 c at the bottom to draw the
lead wire 19 to the outside.
[0034]
In the ultrasonic atomizer 1 of FIG. 9, the ultrasonic transducer 2 placed in the recess 12 b of the
desorption plate 12 is bonded with a caulking material 20 and fixed by a waterproof structure
without using packing and a ring plate. . The ultrasonic transducer 2 also leads the lead wire 19
to the outside from the through hole 12c opened at the bottom of the recess 12b. The caulking
material 20 is also filled between the through holes 12 c and the lead wires 19 to form a
waterproof structure that does not leak water.

[0035]
The ultrasonic atomizer 1 of FIG. 10 has a through hole 12a opened in the desorption plate 12,
and the vibrating surface 2A is positioned in the through hole 12a to fix the ultrasonic
transducer 2 on the lower surface of the desorption plate 12. doing. In order to fix the ultrasonic
transducer 2 to the desorption plate 12, a fixing tool 21 is fixed to the bottom of the desorption
plate 12. The ultrasonic transducer 2 is fixed to the removable plate 12 with a waterproof
structure via packings 16 disposed above and below the outer peripheral portion. The fixture 21
has a ring shape having a step recess, and a fixing screw 22 penetrating the outer peripheral
edge is screwed into the desorption plate 12 and is fixed to the desorption plate 12. The fixing
tool 21 presses the packing 16 disposed on the lower surface of the ultrasonic transducer 2 at
the bottom surface of the stepped recess, and fixes the ultrasonic transducer 2 to the detachable
plate 12 with a waterproof structure. The fixing tool 21 is provided with a through hole 21A on
the bottom surface of the stepped concave portion, and the lead wire 19 is drawn out therefrom.
[0036]

the ultrasonic atomization chamber 4 shown in these drawings, an opening 13A is provided on
the bottom of the casing 13, and the desorption plate 12 is fixed so as to close the opening 13A
with a waterproof structure. The desorption plate 12 is fixed to the casing 13 in a waterproof
structure via the packing 23. In order to fix the desorption plate 12, a fixing bracket 24 is fixed
to the bottom of the casing 13. The fixing bracket 24 is L-shaped, and is fixed to the casing 13 of
the ultrasonic atomization chamber 4 by pressing the desorption plate 12 with a set screw 25
penetrating the fixing bracket 24. The plurality of ultrasonic transducers 2 fixed to the ultrasonic
atomization chamber 4 in this structure ultrasonically vibrate the solution from the bottom to the
top of the casing 13. The desorption plate 12 is mounted on the bottom surface of the casing 13
of the ultrasonic atomizing chamber 4 so as to close the opening 13A and to be detachable.
[0037]
The desorption plate 12 can also be immersed in the solution of the ultrasonic atomization
chamber 4 to ultrasonically vibrate the solution, as shown in FIG. This structure allows the

desorption plate 12 as a waterproof structure.
[0038]
When the ultrasonic transducer 2 or the ultrasonic power source 3 heats the solution in the
ultrasonic atomization chamber 4, the quality of the solution is degraded. This adverse effect can
be eliminated by forcibly cooling the ultrasonic transducer 2. Furthermore, preferably, the
ultrasonic power supply 3 is also cooled. The ultrasonic power source 3 does not directly heat
the solution, but heats the surroundings to heat the solution indirectly. As shown in FIG. 3, the
ultrasonic transducer 2 and the ultrasonic power source 3 can be disposed in a state in which the
cooling pipe 14 is thermally coupled to them, that is, can be disposed and cooled in a state in
which the cooling pipe 14 is in contact. . The cooling pipe 14 cools the ultrasonic transducer 2
and the ultrasonic power source 3 by flowing liquid or refrigerant cooled by a cooler, or cooling
water such as ground water or tap water.
[0039]
The mist of the solution atomized in the ultrasonic atomization chamber 4 flows into the
collection chamber 5. In order to efficiently flow the mist of the ultrasonic atomization chamber
4 into the recovery chamber 5, the device of FIG. 1 incorporates the ultrasonic atomization
chamber 4 in the recovery chamber 5, and the device of FIG. The ultrasonic atomization chamber
4 is disposed in the upper part of the fifth. The recovery chamber 5 has a sufficiently large
volume as compared to the ultrasonic atomization chamber 4, for example, 2 to 100 times,
preferably 5 to 50 times, more preferably 5 to 20 times the volume of the ultrasonic atomization
chamber 4 Have a volume of The apparatus shown in FIG. 2 is integrally formed by connecting
the ultrasonic atomization chamber 4 and the upper portion of the recovery chamber 5 via a duct
26 which is a communication passage. The mist atomized in the ultrasonic atomization chamber
4 falls slowly and is collected as a solution in the collection chamber 5.
[0040]
The recovery chamber 5 is a closed chamber, and the mist supplied thereto is not discharged to
the outside. Therefore, the mists supplied to the collection chamber 5 collide with each other to
be largely aggregated, or collide with a baffle plate or the like to be largely aggregated and
04-05-2019

recovered as a solution. In the recovery chamber 5, in order to recover the mist more quickly, the
recovery chamber 5 in FIGS. 1 and 2 is provided with a nozzle 6 for sprinkling a solution. The
nozzle 6 is connected to the bottom of the collection chamber 5 via a circulation pump 15. The
circulation pump 15 sucks in the solution collected in the collection chamber 5 and sprays it
from the nozzle 6.

In the ultrasonic separation device shown in the figure, the nozzles 6 are disposed at the top and
the side of the recovery chamber 5. The upper nozzle 6 sprays the solution downward. The side
nozzles 6 spray the solution in the horizontal direction. The solution sprayed from the nozzle 6 is
a sufficiently large water droplet compared to the mist atomized by the ultrasonic atomizer 1,
and the solution drops rapidly inside the collection chamber 5 and is collected when it falls It
collides with the mist floating inside the chamber 5 and falls while collecting the mist. Therefore,
the mist floating in the collection chamber 5 can be collected efficiently and promptly.
[0042]
In the illustrated ultrasonic separation apparatus, the nozzles 6 are disposed on the upper side
and the side surface, but the nozzles may be disposed on the lower part of the collection chamber
5. The lower nozzle sprays the solution upwards. The nozzle sprays the solution at a speed at
which the solution collides with the ceiling of the collection chamber 5 or at a speed rising to the
vicinity of the ceiling. The solution sprayed so as to ascend to the vicinity of the ceiling changes
direction downward and falls in the vicinity of the ceiling, so that it contacts the mist when it
ascends and descends, and the mist is efficiently recovered.
[0043]
The collection chamber 5 of FIG. 12 has a plurality of baffles 7 disposed therein. The baffle plate
7 is disposed in a vertical posture with a gap that allows mist to pass between the baffle plate 7
and the adjacent one. The vertical baffles 7 allow the mist to collide with the surface and allow
the adhering solution to naturally flow down and be recovered. The baffle plate 7 in the figure
has a surface as an uneven surface so that the mist can be more efficiently brought into contact
and collected.

Further, the recovery chamber 5 of FIG. 12 is provided with a fan 9 for forcibly blowing and
stirring the mist. The fan 9 stirs the mist in the collection chamber 5. The mists to be stirred
collide with each other and aggregate, or collide with the surface of the baffle plate 7 and
aggregate. The mist that agglomerates falls quickly and is collected. The fan 9 in the figure blows
the mist in the recovery chamber 5 downward and circulates it.
[0045]
The ultrasonic separating apparatus of FIG. 13 is provided with a mist vibrator 8 in the collection
chamber 5 which vibrates the mist to increase the probability of collision with each other. The
mist vibrator 8 includes an electric vibration-mechanical vibration converter that vibrates the gas
in the recovery chamber 5 and a vibration power source that drives the electric vibrationmechanical vibration converter. The electrical vibration-mechanical vibration converter is a
speaker that emits sound at an audible frequency, an ultrasonic transducer that emits an
ultrasonic wave higher than the audible frequency, or the like. In order to vibrate the mist
efficiently, the electric vibration-mechanical vibration converter resonates the vibration radiated
from the electric vibration-mechanical vibration converter in the recovery chamber 5. In order to
realize this, the electrical vibration-mechanical vibration transducer is vibrated at a frequency at
which the recovery chamber 5 resonates. In other words, the recovery chamber 5 is designed to
resonate with the vibration radiated from the electric vibration-mechanical vibration converter.
[0046]
Ultrasound is a high frequency that exceeds human audio frequencies, so it is not audible to the
ear. For this reason, the mist vibrator 8 that radiates ultrasonic waves vibrates the gas in the
collection chamber 5 violently, in other words, the output of the electric vibration-mechanical
vibration converter becomes extremely large to harm human beings. I have not. For this reason,
the ultrasonic wave vibrates the mist violently to cause it to collide efficiently, and has a feature
of being able to be quickly recovered.

In the above-described ultrasonic separation apparatus, since the device for aggregating the mist
efficiently is disposed in the collection chamber 5, the mist can be more quickly aggregated to
form a high concentration solution. Furthermore, although not shown, the ultrasonic separation
device of the present invention incorporates all of the nozzle for spraying the solution, the fan for
stirring the mist, and the vibrator for vibrating the mist in the recovery chamber 5, and is most
efficient. The mist can be aggregated. In addition, two devices for aggregating the mist can be
incorporated to efficiently condense the mist.
[0048]
The ultrasonic atomization chamber 4 and the recovery chamber 5 are preferably filled with an
inert gas. In this apparatus, deterioration of the solution in the ultrasonic atomization chamber 4
and the recovery chamber 5 is prevented by the inert gas. Therefore, a high concentration
solution can be obtained in a higher quality state.
