Description

  The present invention relates to a method and an apparatus for atomizing a solution into a fine mist, in particular, a method for obtaining a high-concentration solution as a target substance by atomizing alcohol, alcohol, petroleum, crude oil, etc. The present invention relates to a method and apparatus for atomizing a solution that is optimal for a humidifier or the like that is used in an apparatus or that atomizes water into a mist and vaporizes it into the air.

The inventor has developed an apparatus for atomizing a solution into a mist and recovering the mist to separate a high-concentration alcohol from the alcohol. (See Patent Document 1)
JP 2001-314724 A

  This separation device, for example, ultrasonically vibrates a stock solution containing alcohol to form a fine mist in the carrier gas, and separates and recovers the atomized mist from the carrier gas to separate a higher concentration alcohol solution than the stock solution. it can. This type of separation apparatus can separate high-concentration alcohol with less energy than an apparatus that heats and vaporizes the stock solution.

  In addition, a humidifier that ultrasonically vibrates water into a mist and forcibly blows it into the air to vaporize it into the air is a humidifier that consumes a large amount of water with less power consumption than a method that vaporizes water with heat. It can be released and humidified.

  It is important for a device that makes a solution a mist how efficiently the solution can be made into a mist by ultrasonically vibrating the solution. This is because the energy that can be atomized into the mist determines the amount of energy used, and the energy used increases as the efficiency decreases. For example, a method of atomizing a solution into a mist can be used as a method of separating water from a low-concentration alcohol obtained by fermenting an organic substance into a high-concentration alcohol. This is because the low-concentration alcohol is atomized into mist and recovered to become high-concentration alcohol. Low-concentration alcohol is produced by fermenting organic matter that is waste. However, this method cannot produce high-concentration alcohol. This is because microorganisms involved in fermentation cannot be actively activated with high-concentration alcohol. However, this method is characterized in that a large amount of low-concentration alcohol can be produced by effectively utilizing a huge amount of generated waste. Currently, however, considerable energy is consumed to concentrate low-concentration alcohol to high-concentration alcohol. This is because low-concentration alcohol is distilled into high-concentration alcohol. Therefore, low-concentration alcohol that can be produced at low cost consumes a large amount of energy in order to make high-concentration alcohol, and the cost is high. It is important how low-concentration alcohol can be made into high-concentration alcohol by low-cost processing. The method of atomizing low-concentration alcohol into mist does not cause the alcohol to be vaporized by the heat of vaporization as in the distillation method, so that energy consumption can be reduced. However, it is important how efficiently this method can atomize low-concentration alcohol into mist.

  Furthermore, it is important to increase the efficiency of atomizing water into a mist in a humidifier that oscillates water ultrasonically to reduce the power consumption and efficiently humidify.

  A state in which the solution is atomized into mist by a conventional atomization method is shown in FIG. In this method, the solution is ultrasonically vibrated by the ultrasonic vibrator 2 disposed at the bottom of the solution. As shown in the figure, the ultrasonically vibrated solution has a liquid surface protruding in a columnar shape and atomized from the surface of the protruding portion into a mist. When the solution is atomized into a mist in this state, a part of the energy of the ultrasonic vibration is consumed to push up the solution in a columnar shape. For this reason, the energy of ultrasonic vibration cannot be efficiently used for the mist of the solution, and the efficiency of atomizing into the mist is lowered.

  The present invention has been developed with the object of eliminating this drawback. An object of the present invention is to provide an atomization method and apparatus capable of efficiently atomizing a solution into a mist by efficiently utilizing ultrasonic vibration for atomization of the solution.

  The solution atomization method of the present invention has the following configuration in order to achieve the aforementioned object. In the solution atomization method, the solution is ultrasonically vibrated by the ultrasonic vibrator 2 and atomized into a mist in a gas. In the solution atomization method, the solution is supplied to the inside of the cylinder 6 and the pressure mechanism 5 is used to make the pressure of the solution inside the cylinder relatively higher than the pressure of the gas to be atomized into the mist. The solution is jetted into the gas from the extrusion port 12 of the cylindrical body 6 in a state where the acoustic wave is vibrated, and the solution jetted from the cylindrical body 6 is ultrasonically vibrated and atomized into a mist.

  The solution atomization method of the present invention uses the pressure mechanism 5 as the solution pump 10 so that the liquid level of the solution inside the cylinder is not less than 1/4 of the height (h) of the cylinder 6 without ultrasonic vibration. Thus, the solution can be pressurized with the solution pump 10.

  In the solution atomization method of the present invention, the pressure mechanism 5 is a blower 8 that sucks and depressurizes a gas that atomizes the solution into a mist. The pressure of the gas can be reduced by sucking the gas with the blower 8 so that the height (h) of the body 6 is ¼ or more.

  In the solution atomization method of the present invention, the cylindrical body 6 can be formed into a cylindrical shape. Furthermore, the solution atomization method of the present invention can make the cylindrical body 6 a conical horn that narrows toward the extrusion port 12. Furthermore, in the solution atomization method of the present invention, an exponential horn can be used for the cylinder 6.

  In the solution atomization method of the present invention, gas can be injected around the extrusion port 12. Further, in the solution atomization method of the present invention, an inert gas such as nitrogen, helium, or argon can be used as the gas injected from the extrusion port 12.

The solution atomizing apparatus of the present invention has the following configuration in order to achieve the above-described object.
The solution atomization device supplies a high-frequency power to the ultrasonic transducer 2 connected to the ultrasonic transducer 2 and a plurality of ultrasonic transducers 2 that ultrasonically vibrate the solution to atomize the gas into a mist. And a high frequency power source 3 for ultrasonic vibration. Further, the solution atomizing device is provided with a cylinder 6 for supplying the solution to the inside and discharging the solution from the extrusion port 12 into the gas, and a gas for atomizing the pressure of the solution inside the cylinder into the mist. And a pressure mechanism 5 for making the pressure relatively higher than the pressure. The atomizing device has the pressure mechanism 5 to make the pressure of the solution relatively higher than the pressure of the gas, and jets the solution from the extrusion port 12 into the gas in a state of ultrasonic vibration, and jets from the cylinder 6. The solution to be atomized by ultrasonic vibration with the ultrasonic vibrator 2

  The solution atomizing apparatus of the present invention uses the pressure mechanism 5 as a solution pump 10 so that the liquid level of the solution inside the cylinder is not less than 1/4 of the height (h) of the cylinder 6 without ultrasonic vibration. Thus, the solution can be pressurized with the solution pump 10.

  The solution atomizing apparatus of the present invention uses the pressure mechanism 5 as a blower 8 that sucks and depressurizes a gas that atomizes the solution into a mist. The pressure of the gas can be reduced by sucking the gas with the blower 8 so that the height (h) of the body 6 is ¼ or more.

  In the solution atomization apparatus of the present invention, the cylindrical body 6 can be cylindrical. In the solution atomizing apparatus of the present invention, the cylindrical body 6 can be a conical horn that narrows toward the extrusion port 12. In the solution atomization apparatus of the present invention, the cylindrical body 6 can be an exponential horn.

  The solution atomization apparatus of the present invention can open the fumarole 14 around the extrusion port 12. Further, in the solution atomization apparatus of the present invention, the gas source can supply an inert gas such as nitrogen, helium, argon, or the like to the fumarole 14.

  The present invention is characterized in that the solution can be efficiently atomized into a mist. In the state where the present invention supplies the solution to the cylinder, and the pressure mechanism causes the pressure of the solution inside the cylinder to be relatively higher than the pressure of the gas atomized in the mist, and the ultrasonic vibration is performed. This is because the solution is jetted into the gas from the extrusion port of the cylinder, and the solution jetted from the cylinder is ultrasonically vibrated and atomized into mist. In the present invention, the pressure mechanism causes the solution to be atomized into mist by ultrasonically oscillating in a state where the pressure of the solution inside the cylinder is higher than the pressure of the gas. The pressure mechanism is an inexpensive device such as a pump or a blower, and can provide a pressure difference between the solution and the gas. Thus, in the present invention, the pressure of the solution is made higher than the pressure of the gas by the pressure mechanism, and the solution is jetted into the gas from the extrusion port of the cylinder while being ultrasonically vibrated, and jetted into the gas. Since the solution is atomized into mist by ultrasonic vibration, the solution can be efficiently misted by ultrasonic vibration without consuming the part of the energy of ultrasonic vibration to push up the solution into a columnar shape as before. Can be atomized.

  Furthermore, this invention can be made into the structure which ultrasonically vibrates the solution ejected from an extrusion port through the solution in a cylinder. According to this structure, the cylindrical body can efficiently transmit ultrasonic vibration, and the solution ejected from the extrusion port can be more efficiently ultrasonically vibrated. For this reason, the solution ejected from the extrusion port can be atomized into mist more efficiently.

  Embodiments of the present invention will be described below with reference to the drawings. However, the example shown below illustrates the atomization method and the atomization device of the solution for embodying the technical idea of the present invention, and the present invention describes the atomization method and the atomization device as follows. Not specific.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The atomization method and the atomization apparatus of the present invention ultrasonically vibrate the solution to atomize the gas into mist. Hereinafter, as an embodiment of the present invention, a solution separation device including an atomization device will be described. The solution separation apparatus shown below is an atomization method and an atomization apparatus according to the present invention, wherein a solution containing two or more substances is ultrasonically vibrated to be atomized into mist, and the atomized mist is aggregated and collected. Separate the solution. However, the present invention does not specify the use of the atomization method and the atomizer as a solution separation device. The atomization method and the atomization apparatus of the present invention can also be used in a humidifier or the like that atomizes water into mist and vaporizes it into the air.

A solution separation apparatus described below separates a high concentration specific solution from a solution containing at least two kinds of substances. The separation device does not specify the solvent and solute of the solution, but the solvent is mainly water. However, in addition to water, an organic solvent such as alcohol can also be used. The solution is, for example, as follows.
(1) Sake, beer, wine, vinegar, mirin, spirits, shochu, brandy, whiskey, liqueur
(2) A solution containing a fragrance such as pinene, linalool, limonene, polyphenols, a fragrance component or a fragrance component

(7) Saturated hydrocarbons of alkanes, cycloalkanes, unsaturated hydrocarbons of alkenes, cycloalkenes, alkynes, or organic compounds belonging to any of ethers, thioethers or aromatic hydrocarbons, or their conjugates A solution containing a substance in which at least one hydrogen atom or functional group is replaced by a carbonyl group
(8) Saturated hydrocarbon alkane, cycloalkane, unsaturated hydrocarbon alkene, cycloalkene, alkyne, or an organic compound belonging to any of ether, thioether or aromatic hydrocarbon, or a combination thereof A solution containing a substance in which at least one hydrogen atom or functional group is replaced by a carboxyl group

  When a solution containing two or more substances is ultrasonically vibrated to separate the mist from the solution, and the separated mist is aggregated and recovered, the solution recovered from the mist and the solution remaining without becoming a mist are contained. The substance concentration is different. For example, when an alcohol aqueous solution is atomized into mist by ultrasonic vibration and the atomized mist is recovered, the alcohol becomes higher in concentration than the remaining alcohol without becoming mist. The reason why the alcohol concentration of the solution obtained by aggregating and recovering the mist is high is that the alcohol is more easily atomized into the mist than water by the ultrasonic vibration.

  Hereinafter, the separation apparatus which atomizes alcohol into mist with the atomization method and the atomization apparatus of the present invention, and collects the mist to separate high-concentration alcohol using the solution as alcohol will be described. However, the separation device does not specify the solution to be atomized by the atomizer as alcohol. This is because it can be used for separation of the above-mentioned solution that can be atomized into mist and separated, or other solutions.

  The solution separation device shown in FIGS. 2 to 5 includes an atomization device 1 that atomizes the solution into a mist, and a recovery unit 40 that collects the mist atomized by the atomization device 1.

  The atomization apparatus 1 includes an ultrasonic atomization chamber 4 having a closed structure to which a solution is supplied, an ultrasonic vibrator 2 that ultrasonically vibrates the solution in the ultrasonic atomization chamber 4 and atomizes it into a mist, A cylinder 6 disposed above the acoustic wave oscillator 2, a pressure mechanism 5 for making the pressure of the solution inside the cylinder relatively higher than the pressure of the gas atomized in the mist, and an ultrasonic oscillator 2 and a high-frequency power source 3 connected to 2.

  The atomizing apparatus 1 shown in FIGS. 2 to 4 includes an ultrasonic atomizing chamber 4 provided in a casing 49 to which a solution is supplied, and a plurality of ultrasonic vibrators 2 are fixed to the bottom surface of the casing 49. ing. The atomizing apparatus 1 shown in FIG. 5 has an ultrasonic atomizing chamber 4 divided into a plurality of sections, and these ultrasonic atomizing chambers 4 are arranged inside a closed chamber 99 having a sealed structure. . In the atomizing apparatus 1 of FIG. 5, a plurality of casings 49 constituting each ultrasonic atomizing chamber 4 and a base 90 connected so that these casings 49 can be attached and detached are arranged in a closed chamber 99. Has been established.

  The solution is supplied to the ultrasonic atomization chamber 4 by the supply mechanism 7. The supply mechanism 7 shown in FIGS. 2, 3, and 5 supplies a solution tank 11 that stores the solution supplied to the ultrasonic atomization chamber 4, and supplies the solution in the solution tank 11 to the ultrasonic atomization chamber 4. The solution pump 10 is provided. The solution pump 10 has a suction side connected to the solution tank 11 and a discharge side connected to the ultrasonic atomization chamber 4. The supply mechanism 7 is configured to supply a solution from the solution tank 11 to the ultrasonic atomization chamber 4 continuously with the solution pump 10. Further, the supply mechanism 7 shown in FIG. 4 provides a difference in level between the solution tank 11 and the ultrasonic atomization chamber 4 without connecting a solution pump to the solution tank 11, so that the ultrasonic atomization chamber is separated from the solution tank 11. 4 is configured to supply a solution.

  The ultrasonic atomization chamber 4 does not atomize all supplied solutions as mist. This is because when all the solutions are atomized and collected by the collection unit 40, the concentration of the target substance such as alcohol in the solution supplied to the ultrasonic atomization chamber 4 and the solution collected by the collection unit 40 becomes the same. The solution supplied to the ultrasonic atomizing chamber 4 is atomized as a mist, and the concentration of the target substance decreases as the volume decreases. For this reason, the density | concentration of the target substance contained in mist also falls gradually. The solution in the ultrasonic atomizing chamber 4 is preferably replaced with a new one when the concentration of the target substance decreases.

  2 and 3 supplies the solution from the solution tank 11 while discharging the solution in the ultrasonic atomizing chamber 4, and the concentration of the target substance such as alcohol in the solution in the ultrasonic atomizing chamber 4. Is prevented from falling. For example, the atomizing device 1 atomizes a solution having a target substance concentration of 10 to 50% by weight, and when the concentration of the target substance decreases, the solution in the ultrasonic atomizing chamber 4 and the solution tank 11 is replaced with a new one. Can be replaced. That is, the solution can be replaced by replacing the solution with a new one after a certain period of time. Further, as indicated by an arrow A in the figure, the solution in the ultrasonic atomizing chamber 4 is discharged outside without circulating to the solution tank 11 to prevent the concentration of the target substance contained in the solution tank 11 from being lowered. You can also

  The ultrasonic atomizing chamber 4 has a cylindrical body 6 disposed therein. The cylindrical body 6 is disposed above the ultrasonic vibrator 2 and efficiently scatters mist from the solution that is ultrasonically vibrated by the ultrasonic vibrator 2. The cylindrical body 6 has a cylindrical shape with an opening 12 at the upper end. The atomizing device 1 supplies the solution supplied to the ultrasonic atomizing chamber 4 to the inside of the cylinder 6 and applies ultrasonic vibration toward the extrusion port 12 to the solution supplied to the inside of the cylinder. Then, the mist is atomized from the extrusion port 12 and scattered. The ultrasonic transducer 2 shown in the figure emits ultrasonic waves upward. Accordingly, the cylindrical body 6 is disposed in a vertical posture above the ultrasonic transducer 2.

  The atomizing apparatus 1 shown in FIGS. 2 to 4 has a plurality of cylinders 6 disposed below the ultrasonic atomizing chamber 4. The plurality of cylinders 6 are arranged on the same plane with their lower ends connected by a connecting plate 31. The ultrasonic atomization chamber 4 has a lower part to which a solution is supplied, and has a cylindrical structure 6, a connecting plate 31, and a casing 49 that are closed. It is made to discharge | emit into gas from the extrusion port 12 of the cylinder 6. FIG. Further, the plurality of cylindrical bodies 6 are disposed away from the ultrasonic transducers 2, and are disposed on the bottom surface of the casing 49 and below the respective cylindrical bodies 6. Has been established. This atomizing device guides the ultrasonic vibration of the ultrasonic vibrator 2 positioned below the lower end of the cylindrical body 6 and scatters it as mist from the extrusion port 12 at the upper end of the cylindrical body 6. Further, in the atomizing apparatus 1 shown in FIG. 5, the cylindrical bodies 6 are arranged in the respective casings 49. These cylinders 6 are closed by fixing the lower end to the bottom plate 62 of the casing 49, so that the solution is supplied into the cylinder 6 and the solution is supplied to the ultrasonic atomization chamber 4. Yes.

  Furthermore, the atomizing device of the present invention uses the pressure of the solution inside the cylinder with the pressure mechanism 5 in order to efficiently use the ultrasonic vibration for atomizing the solution and efficiently atomize the solution into the mist. The liquid is jetted into the gas from the extrusion port 12 opened at the upper end of the cylindrical body 6 in a state where the pressure is relatively higher than the pressure of the gas atomized into the mist and is ultrasonically vibrated. In this apparatus, the solution ejected into the gas from the extrusion port 12 at the upper end of the cylindrical body 6 is ultrasonically vibrated by the ultrasonic vibrator 2 and atomized into a mist in the gas.

  The pressure mechanism 5 is supplied to the inside of the cylinder in a state in which the pressure of the solution inside the cylinder is relatively higher than the pressure of the gas that atomizes into the mist, as shown in FIG. The liquid level of the solution is raised from the lower end of the cylinder 6. That is, the pressure mechanism 5 provides a pressure difference between the solution inside the cylinder and the gas in the ultrasonic atomization chamber, and the pressure level increases the liquid level of the solution inside the cylinder. As described above, the atomizing device that raises the liquid level of the solution inside the cylinder by the pressure mechanism 5 efficiently uses the solution without consuming a part of the energy of the ultrasonic vibration to push up the solution in a columnar shape. Can atomize well into mist. Therefore, the liquid inside the cylinder can be efficiently ultrasonically vibrated, and the solution can be atomized into mist while being ejected into the gas from the extrusion port 12 opened at the upper end of the cylinder 6.

  In the pressure mechanism 5, for example, in a state where no ultrasonic waves are emitted, the liquid level of the solution inside the cylinder is ¼ or more, preferably １ ／ or more of the height (h) of the cylinder 6. A pressure difference can be provided between the solution inside the cylinder and the gas in the ultrasonic atomization chamber so that it becomes 1/2 or more. Furthermore, as shown in FIG. 7, the pressure mechanism 5 can also be a pressure difference that is jetted out in a state where the solution inside the cylinder overflows and is discharged from the extrusion port 12 in a state where no ultrasonic waves are emitted.

  The pressure mechanism 5 shown in FIGS. 2 and 5 is a solution pump 10. The solution pump 10 shown in the drawing sucks the solution in the solution tank 11 and supplies it to the ultrasonic atomizing chamber 4 to make the pressure inside the cylinder 6 relatively higher than the pressure in the gas. The pressure mechanism 5 pressurizes the solution in the ultrasonic atomization chamber to increase the liquid level inside the cylinder 6 without ultrasonic vibration, and in the state of ultrasonic vibration, The solution is ejected from the outlet 12 into the gas. The pressure mechanism 5 shown in FIG. 2 makes the pressure of the supply path 43 that the solution pump 10 supplies to the ultrasonic atomization chamber 4 higher than the pressure of the discharge path 44 that is discharged from the ultrasonic atomization chamber 4. The pressure of the solution supplied into the cylindrical body is set higher than the pressure of the gas. In order to control the flow rate in the discharge path 44, a control valve 45 is provided in the discharge path 44. However, the pressure mechanism continuously supplies the solution from the solution pump without discharging the solution in the ultrasonic atomizing chamber, that is, without connecting the discharge path to the ultrasonic atomizing chamber, The internal pressure can also be made relatively higher than the pressure in the gas.

  The pressure mechanism 5 shown in FIG. 3 is a blower 8 that sucks the gas in the ultrasonic atomizing chamber 4 and depressurizes the ultrasonic atomizing chamber 4. The atomizing apparatus 1 shown in the drawing sucks the gas in the ultrasonic atomizing chamber 4 with the blower 8, reduces the pressure in the ultrasonic atomizing chamber, and increases the liquid level inside the cylindrical body 6. At the same time, the solution is jetted into the gas from the extrusion port 12 in a state of ultrasonic vibration.

  Further, the pressure mechanism 5 shown in FIG. 4 has a solution tank 11 of a supply mechanism 7 that supplies a solution to the ultrasonic atomizing chamber 4 at a high position with respect to the cylinder 6, and the cylinder is caused by this height difference. The pressure of the solution supplied to 6 is increased. This pressure mechanism 5 has the feature that it can pressurize the solution in the ultrasonic atomization chamber without providing a solution pump. This pressure mechanism 5 can adjust the pressure inside the cylinder by adjusting the height of the liquid level of the solution tank 11. Furthermore, the supply mechanism 7 shown in the figure is provided with a control valve 46 in the supply path 43 that supplies the ultrasonic atomizing chamber 4 so as to adjust the amount of solution to be supplied.

  Furthermore, although not shown, the pressure mechanism pressurizes the solution supplied to the ultrasonic atomization chamber by the height difference of the solution tank or the solution pump, and sucks and depressurizes the gas in the ultrasonic atomization chamber with a blower. A pressure difference can also be provided between the solution inside the cylinder and the gas in the ultrasonic atomization chamber.

  As shown in FIG. 6, the pressure mechanism 5 having the above structure is configured to adjust the liquid level inside the cylinder 6 without the ultrasonic vibration due to the difference between the pressure of the solution inside the cylinder and the pressure in the gas. The height is raised to 1/4 or more of the height (h) of the body 6, or as shown in FIG. 7, the solution is ejected from the extrusion port 12 into the gas. Further, the atomizing device 1 applies ultrasonic vibration to the solution by the ultrasonic vibrator 2 in a state where the liquid level inside the cylinder 6 is increased or in a state where the solution is ejected from the extrusion port 12. The solution is atomized into mist. Thus, in the state where the liquid level inside the cylindrical body 6 is increased by the pressure mechanism 5 or the state in which the solution is ejected from the extrusion port 12, the ultrasonic vibration is applied to atomize the mist. The feature that the energy of sonic vibration can be effectively used for atomization of the solution is realized.

  The cylindrical body 6 shown in the figure is a conical horn that becomes gradually thinner toward the upper end. However, the cylindrical body can also be an exponential horn whose inner surface has an exponential curve. The cylindrical body 6 of the conical horn or the exponential horn has a feature that the ultrasonic vibration can be efficiently transmitted to the inside and the solution can be efficiently atomized into the mist. However, in the present invention, the cylindrical body can be formed into a cylindrical shape, an elliptical cylindrical shape, or a polygonal cylindrical shape.

  The inner shape of the lower end opening of the cylindrical body 6 is smaller or larger than the outer shape of the ultrasonic transducer 2 so that the ultrasonic vibration can be efficiently transmitted to the inside, and the ultrasonic vibration rises along the inner surface. Like that. For example, the inner diameter of the opening at the lower end of the cylindrical body 6 is 50 to 150%, preferably 60 to 100% of the outer diameter of the ultrasonic transducer 2.

  Furthermore, the height (h) of the cylinder 6 and the size of the extrusion port 12 are such that the solution rises along the inside of the cylinder 6, that is, the inner surface of the cylinder 6 and the solution in the cylinder It is designed so that the solution rises so that there is no air layer between. That is, the solution pressurized by the pressure mechanism 5 rises along the inside of the cylindrical body 6, or the liquid column due to ultrasonic vibration rises along the inside of the cylindrical body 6, and the extrusion port 12 is caused by ultrasonic vibration. Designed to scatter in the vicinity of the mist. Therefore, the height (h) of the cylindrical body 6 and the size of the extrusion port 12 are set to optimum values in consideration of the size, output, frequency, and pressure difference due to the pressure mechanism 5 of the ultrasonic vibrator 2. Designed. The height (h) of the cylinder 6 can be, for example, 0.1 to 10 cm, preferably 1 to 10 cm.

  The atomization apparatus 1 shown in FIGS. 2 to 4 connects a plurality of cylinders 6 to a connection plate 31 in the lower part of the ultrasonic atomization chamber 4. An example of the connection structure of the plurality of cylinders 6 and the connection plate 31 is shown in the enlarged sectional view of FIG. The cylinder 6 shown in this figure has a structure in which the lower part can be detachably connected to the connecting plate 31. The connecting plate 31 has a through hole 32 in the connecting portion of the cylinder 6, passes through the through hole 32, supplies the solution to the inside of the cylinder 6, and guides the ultrasonic vibration to the inside. I have to.

  Further, the cylindrical body 6 shown in FIG. 8 has an opening 14 for supplying gas to the mist atomized from the extrusion port 12 and connects the injection port 14 to a gas source (not shown). . The gas source can supply an inert gas such as nitrogen, helium, or argon to the fumarole 14. The gas supplied from the gas source is supplied to the mist from the blow port 14, and the mist sprayed from the extrusion port 12 is atomized into the gas. The gas containing the mist atomized in this state is aggregated in the recovery unit 40 to recover the solution.

  8 has an outer cylinder 6b disposed outside the inner cylinder 6a, and a gas duct 15 is provided between the inner cylinder 6a and the outer cylinder 6b. The duct 15 is connected to an air outlet 14 opened at the upper end of the cylindrical body 6. The gas supplied to the duct 15 is exhausted from the blow port 14. The fumarole 14 is opened in a slit shape around the upper end of the cylindrical body 6. The slit-shaped air outlet 14 exhausts gas in a ring shape. Mist is released inside the gas exhausted in a ring shape. The cylinder 6 having this structure sprays mist on the inside of fresh gas. For this reason, the solution can be efficiently atomized into a mist. This is because the mist is atomized into a gas having a low solution concentration.

  The cylinder 6 in FIG. 8 is coupled to the coupling duct 16 that is the coupling plate 31 so as to be detachable. The connection duct 16 is provided with a supply duct 19 inside. The supply duct 19 is connected to the duct 15. The supply duct 19 of the connection duct 16 is connected to a gas source. As shown in FIGS. 2 to 4, a plurality of cylinders 6 are connected to the connection plate 31. 8 is provided with a male screw 17 on the outer periphery of the lower end, and a connecting duct 16 is provided with a female screw hole 18 into which the male screw 17 of the cylindrical body 6 is screwed.

That is, the cylinder 6 is connected to the connection duct 16 in an airtight state.

  The above atomizing device 1 ultrasonically vibrates the ultrasonic vibrator 2 and scatters the solution from the extrusion port 12 of the cylindrical body 6 as a mist. The solution is ultrasonically vibrated inside the cylinder 6 and scattered from the extrusion port 12 as mist. The atomizing apparatus 1 shown in the figure has an ultrasonic transducer 2 arranged upward. The ultrasonic transducer 2 emits ultrasonic waves in the vertical direction upward from the bottom toward the inside of the cylinder 6 to ultrasonically vibrate the solution inside the cylinder. The solution inside the cylinder is jetted into the gas from the extrusion port 12 of the cylinder 6 in a state of being ultrasonically vibrated, and is atomized into the mist from the extrusion port 12 of the cylinder 6 into the gas.

  2 and 3, in order to efficiently collect the mist scattered from the extrusion port 12 of the cylinder 6 and circulate it through the circulation duct 41, above the extrusion port 12 of the cylinder 6, A mist suction section 9 is provided. The suction portion 9 shown in the figure is a cylindrical pipe and is arranged in a vertical posture above the cylindrical body 6. The suction portion 9, which is a cylindrical pipe, has a lower end disposed above the cylindrical body 6 and an upper end extending above the ultrasonic atomization chamber 4. The suction part 9 shown in the figure is located at the upper end edge of the cylindrical body 6 and arranges the lower end edge of the cylindrical pipe. However, the suction part can be arranged in a state where the lower end part is wrapped on the upper part of the cylinder, or the lower end edge can be arranged away from the upper end edge of the cylinder. Further, the opening at the lower end of the suction portion 9 has a larger opening area than the extrusion port 12 of the cylindrical body 6 so that the mist scattered from the upper end of the cylindrical body 6 can be collected without leakage. The upper end of the suction part 9 is connected to the upper part of the ultrasonic atomizing chamber 4, and this connection part is connected to the circulation duct 41 so that the mist collected by the suction part 9 is circulated to the circulation duct 41. ing. However, the inhalation part is not necessarily provided.

  Furthermore, the atomization apparatus shown in FIGS. 2 to 4 has a discharge passage 47 connected to the ultrasonic atomization chamber 4 in order to recover the solution that has been overflowed and ejected from the extrusion port 12 of the cylindrical body 6. . The liquid ejected from the extrusion port 12 of the cylinder 6 in the state of ultrasonic vibration is atomized into the mist in the gas by the ultrasonic vibration, but the cylinder is partially in a solution state without being atomized. Flow down around 6. In order to collect this solution, a discharge passage 47 is connected to the ultrasonic atomization chamber 4. The solution recovered in the discharge path 47 is circulated again to the solution tank 11 or is discharged to the outside as indicated by an arrow B in the figure.

  Furthermore, as shown in FIGS. 9 to 11, the atomizing device 1 shown in FIG. 5 fixes the lower end of the cylindrical body 6 to the bottom surface of the casing 49 to which the solution is supplied. The casing 49 has a cylindrical shape with the bottom closed, and is detachably attached to a predetermined position of the base 90. The casing 49 shown in the drawing has a rectangular tube shape with a horizontal cross-sectional shape being a square. However, the cylindrical casing may have a cross-sectional shape that is a triangle or a polygon that is a pentagon or more, or a circle or an ellipse. The cylindrical casing 49 is closed at the bottom with a bottom plate 62, and the ultrasonic vibrator 2 is fixed to the bottom plate 62, and the cylindrical body 6 is fixed above the ultrasonic vibrator 2. ing. The cylindrical body 6 shown in FIGS. 9 to 11 has an inner shape at the lower end larger than the outer shape of the ultrasonic transducer 2 so that the ultrasonic vibration rises along the inner surface. For example, the inner shape of the lower end of the cylindrical body 6 is 100 to 500%, preferably 150 to 300% of the outer diameter of the ultrasonic transducer 2.

  The ultrasonic transducer 2 fixed to the bottom plate 62 is ultrasonically vibrated with electric power supplied from the high frequency power source 3 by connecting an electrode provided on the lower surface to the high frequency power source 3. The high frequency power source 3 is connected to the ultrasonic transducer 2 via the lead wire 27 and outputs a high frequency output to the ultrasonic transducer 2. The casing 49 shown in the figure stores the electronic components constituting the high-frequency power source 3 in a storage chamber 64 provided on the bottom plate 62 of the casing 49, and the ultrasonic vibrator 2 is fixed to the opening of the storage chamber 64.

  The casing 49 is provided with a storage chamber 64 having an upper opening in the bottom plate 62. In the casing 49 shown in the figure, a storage case 63 is connected to the bottom plate 62, and a concave storage chamber 64 is provided inside the storage case 63. The storage case 63 has a cylindrical shape that closes the bottom. In the illustrated casing 49, the bottom plate 62 and the storage case 63 are integrated. The storage case 63 is provided with electronic components constituting the high-frequency power supply 3 at the bottom of the storage chamber 64, and is embedded in an insulating resin 56 such as urethane resin or phenol resin. Further, the storage case 63 is provided with a stepped portion 65 on the inner surface of the opening edge in order to fix the ultrasonic transducer 2 to the opening. The ultrasonic transducer 2 is arranged in a watertight structure on the stepped portion 65 via the packing 28. The ultrasonic vibrator 2 fixed here is provided with a gap between the insulating resin 56. This is because the ultrasonic vibrator 2 is vibrated without being brought into contact with the insulating resin. The upper opening of the stepped portion 65 is closed by a fixing portion 66 that is fixed to the upper surface of the bottom plate 62. The fixing portion 66 has an opening 67 equal to the inner diameter of the packing 28 and is in close contact with the upper surface of the packing 28 to fix the ultrasonic transducer 2 to the stepped portion 65 in a watertight structure. The fixing portion 66 is fixed to the bottom plate 62 with screws. Although the above-described casing 49 houses the high-frequency power source 3 in the storage chamber 64, the casing can also be provided with a high-frequency power source outside. In this casing, it is not always necessary to fix the ultrasonic vibrator with a watertight structure.

  The casing 49 in the figure has a structure in which the lower end of the cylindrical body 6 is closed with a bottom plate 62 and the solution supplied to the ultrasonic atomizing chamber 4 is supplied into the cylindrical body 6. The cylinder 6 is connected to a solution supply pipe 70 that communicates the inside of the cylinder 6 and the outside of the casing 49 in order to supply the stock solution to the inside. The solution supply pipe 70 shown in the figure is disposed through the bottom plate 62 of the casing 49. The solution supply pipe 70 has one end disposed inside the cylinder 6 and the other end disposed outside the casing 49. The solution supply pipe 70 is connected to the solution supply mechanism 7 shown in FIG. 5, and the supply mechanism 7 supplies the stock solution into the cylindrical body 6. Further, the solution supply pipe 70 shown in FIGS. 9 to 11 has an end portion disposed outside the casing 49 connected to a solution supply mechanism via a detachable connector 71. This connection structure allows the solution supply pipe 70 to be connected to the supply mechanism in a simple, quick and detachable manner.

  The mist atomized at the extrusion port 12 of the cylindrical body 6 is transferred by gas and discharged from the ultrasonic atomizing chamber 4. The ultrasonic atomizing chamber 4 is provided with an air outlet 14 for supplying gas to the mist discharged from the cylindrical body 6. The cylindrical body 6 shown in the figure is provided with an opening 14 for blowing gas around the extrusion port 12. The illustrated cylinder 6 is provided with an outer cylinder 6b outside the inner cylinder 6a, and a gas duct 15 is provided between the inner cylinder 6a and the outer cylinder 6b. The duct 15 has an air outlet 14 opened around the extrusion port 12 at the upper end of the cylindrical body 6, and the gas supplied to the duct 15 is discharged from the air outlet 14.

  Further, the casing 49 shown in the figure is provided with a gas supply pipe 72 for supplying gas to the duct 15 provided in the cylindrical body 6. The gas supply pipe 72 shown in the figure is disposed through the bottom plate 62 of the casing 49. The gas supply pipe 72 has one end disposed inside the duct 15 of the cylindrical body 6 and the other end disposed outside the casing 49. The gas supply pipe 72 is connected to a gas supply source to supply gas. The separation device shown in FIG. 5 is connected to a gas supply pipe using the discharge side of the recovery unit 40 as a gas source, and has a structure for supplying the gas discharged from the recovery unit 40 to the casing 49. This structure can separate mist by circulating gas. However, the separation device can connect the gas source to the gas supply pipe and circulate the air to the duct of the cylinder without circulating the gas. The gas supply pipe 72 shown in FIGS. 9 to 11 has an end portion disposed outside the casing 49 connected to a gas supply source via a detachable connector 73. This connection structure can also connect the gas supply pipe 72 to a supply source simply and quickly.

  Since the cylindrical body 6 having the above structure discharges gas from the blowing port 14 provided around the extrusion port 12, the gas is supplied to the mist atomized at the extrusion port 12 of the cylindrical body 6, thereby efficiently casing the casing 6. 49 has the feature that it can be discharged outside. However, it is not always necessary for the atomizing device to provide an air blowing port around the cylindrical extrusion port. The fumarole can be provided, for example, below the casing, and the solution that is atomized into mist in the gas can be discharged from the extrusion port of the cylindrical body to the outside.

  Furthermore, the casing 49 has a structure in which the solution overflowed and discharged from the extrusion port 12 at the upper end of the cylindrical body 6 is discharged to the outside of the casing 49. In the illustrated casing 49, a solution discharge pipe 74 that connects the inside and the outside of the casing 49 is connected to discharge the solution accumulated around the cylindrical body 6. The solution discharge pipe 74 is disposed through the bottom plate 62 of the casing 49. One end of the solution discharge pipe 74 is disposed outside the cylindrical body 6 at the bottom of the casing 49, and the other end is disposed outside the casing 49. The solution discharge pipe 74 shown in FIGS. 9 to 11 has an end portion disposed outside the casing 49 connected to a solution discharge mechanism (not shown) via a detachable connector 75.

  Furthermore, the ultrasonic unit 60 shown in the drawing draws out a power cord 76 for supplying power to the high frequency power source 3 from the storage case 63, and this power cord 76 is connected to the power source outside the casing 49. The base 90 shown in the figure is provided with an outlet 77 for connecting the power cord 76 to the power source 59. The ultrasonic unit 60 is connected to a power source 59 by connecting a connection plug 78 of a power cord 76 to an outlet 77, and power is supplied from the power source 59. This structure has an advantage that the high frequency power source 3 can be electrically connected to the power source 59 very easily.

  In the casing 49 shown in FIG. 9, the ultrasonic transducer 2 and the cylindrical body 6 are fixed to the bottom plate 62. In this structure, the ultrasonic vibrator 2 and the cylindrical body 6 can be exchanged by exchanging the casing 49. Further, the casing 49 shown in FIGS. 10 and 11 is detachably connected to the bottom plate 62 by a detachable unit 80 formed by integrally connecting the ultrasonic transducer 2 and the cylindrical body 6. In this structure, the ultrasonic transducer 2 and the cylindrical body 6 can be replaced by replacing only the detachable unit 80 without replacing the casing 49.

  The detachment unit 80 is connected so as to be detachable from a circular connection opening 68 provided to open to the bottom plate 62 of the casing 49. The bottom plate 62 is provided with a female screw 69 for screwing a male screw 82 provided on the outer peripheral surface of the attachment / detachment unit 80 on the inner peripheral surface of the connection opening 68. The detachable unit 80 is provided with a male screw 82 on the outer peripheral surface of the connecting plate 81 so that the outer periphery of the circular connecting plate 81 serving as the bottom plate 62 of the casing 2 can be inserted into the connecting opening 68. The detachable unit 80 is connected to the casing 49 by screwing the male screw 82 of the connecting plate 81 into the female screw 69 of the connecting opening 68. Since the connection opening 68 communicates with the inside of the casing 49, the detachable unit 80 needs to be connected to the bottom plate 62 of the casing 49 with a liquid-tight structure. For this reason, the O-ring 30 is sandwiched between the inner surface of the connection opening 68 of the bottom plate 62 and the outer peripheral surface of the detachable unit 80. The O-ring 30 connects the connection opening 68 and the detachment unit 80 in a liquid-tight state, and closes the connection opening 68 with the connection plate 81 of the detachment unit 80 in a liquid-tight manner.

  Further, the ultrasonic transducer 2 can be fixed to the bottom plate 62 with the structure shown in FIG. In the casing 49 in this figure, a storage case 63 that stores the ultrasonic vibrator 2 and the high-frequency power source 3 is detachably connected to the bottom plate 62. In the storage case 63 shown in the figure, an electronic component constituting the high-frequency power source 3 is stored in a storage chamber 64 that opens upward, and is embedded in an insulating resin 56, and the ultrasonic vibrator 2 is disposed at an opening edge. The storage case 63 is connected to the lower end of the bottom plate 62 so that it can be attached to and detached from a connecting recess 83 that opens downward. The connecting recess 83 is provided with a female screw 84 on the inner surface. The housing case 63 is provided with a male screw 85 that is screwed into the female screw 84 of the connecting recess 83 on the outer periphery as an outer shape that can be inserted into the connecting recess 83. The storage case 63 is connected to the connection recess 83 by screwing the male screw 85 into the female screw 84. The connecting recess 83 is open at the bottom, and the ultrasonic vibrator 2 is exposed to the inside of the cylindrical body 6 through the opening 67. Since the connection recess 83 communicates with the inside of the cylindrical body 6, the storage case 63 and the connection recess 83 need to be connected with a watertight structure. For this reason, the O-ring 30 is sandwiched between the inner surface of the connection recess 83 and the outer periphery of the storage case 63, and these are connected in a watertight structure. The storage case 63 shown in the figure has a feature that the ultrasonic vibrator 2 and the high-frequency power source 3 are built in the storage chamber 64, so that only the storage case 63 can be replaced and these can be easily replaced.

  The base 90 has a plurality of mounting recesses 91 formed on the upper surface so that the plurality of casings 49 can be detachably mounted. The mounting recess 91 is a recess in which the lower portion of the casing 49 can be mounted. The lower portion of the casing 49 is fitted into this recess so that the mounting recess 91 can be held in a predetermined position. The illustrated base 90 is provided with a cylindrical partition wall 92 along the outer periphery of the casing 49, and a mounting recess 91 is provided inside the partition wall 92. The mounting recess 91 is provided with a stepped portion 93 on the inner surface, and the stepped portion 93 supports the bottom surface of the casing 49 so that it can be connected to a predetermined position. Furthermore, the mounting recess 91 shown in the drawing includes an elastic support 94 on the inner surface of the partition wall 92 so that the casing 49 can be connected without being displaced. The illustrated elastic support member 94 is a packing made of a rubber-like elastic member, and is in close contact with the inner surface of the mounting recess 91 and the outer surface of the casing 49 so that the casing 49 can be held in a predetermined position. However, the elastic support is not always necessary.

  Further, the mounting recess 91 is provided with a storage chamber 95 for disposing a connecting portion with the ultrasonic unit 60 below the stepped portion 93. The storage chamber 95 is provided with piping and wiring for supplying the ultrasonic atomization chamber 4 with a solution, gas, and electric power or discharging the solution. The casing 49 mounted in the mounting recess 91 connects the solution supply pipe 70 to the supply mechanism, the gas supply pipe 72 to the gas supply source, and the high frequency power supply 3 to the power supply inside the storage chamber 95. Further, the solution discharge pipe 74 is connected to the discharge mechanism.

  Furthermore, the base 90 shown in the drawing is provided with a water storage tank 96 around the mounting recess 91 and stores water in the water storage tank 93. In the illustrated water storage tank 95, a partition wall 92 provided around the casing 49 is used as a peripheral wall, and water is stored using a region partitioned by the partition wall 92 as a water storage tank 96. This water storage tank 96 is formed outside the partition wall 92 of the mounting recess 91 and between the adjacent partition walls 92 of the mounting recess 91. In this way, the structure in which water is stored around the casing 49, in other words, the casing 49 is disposed in the liquid, prevents the mist of alcohol or the like atomized in the ultrasonic atomizing chamber 4 from causing an explosion. Effectively preventing, that is, explosion-proof. Therefore, the water storage tank 96 is designed and provided so as to have a predetermined area and a water storage amount so that the explosion can be effectively prevented.

  The atomizing apparatus 1 having the above structure is configured as an atomizing apparatus 1 by connecting a plurality of casings 49 to a base 90 inside the closed chamber 99. The plurality of ultrasonic units 60 are connected to the base 90, and the solution is supplied from the supply mechanism 7 to the inside of the cylindrical body 6, and the solution in the cylindrical body 6 is superposed from the ultrasonic vibrator 2. A sonic vibration is applied, and the mist is atomized from the extrusion port 12 of the cylindrical body 6. Further, the mist atomized by the plurality of ultrasonic units 60 is discharged to the outside of the casing 49 with the gas supplied from the jet port 14.

  The ultrasonic atomizer 1 shown in FIG. 5 includes a demister 97 that primarily collects mist discharged from the casing 49. In the illustrated ultrasonic atomizer 1, a demister 97 is connected to the upper end of the casing 49 of each ultrasonic unit 60, and the mist contained in the gas discharged from the casing 49 is collected by the demister 97. The ultrasonic atomizer 1 discharges the gas from which the mist is primarily recovered by the demister 97 from the atomization chamber 4.

  As shown in FIGS. 2 to 4, the atomizing apparatus of the above embodiment includes a plurality of cylinders 6 and the ultrasonic transducer 2 in one ultrasonic atomizing chamber 4, or as shown in FIG. 5. As described above, since the plurality of ultrasonic atomizing chambers 4 including the cylindrical body 6 and the ultrasonic vibrator 2 are provided, there is a feature that a large amount of solution can be efficiently atomized into a mist. However, although not shown, the atomization apparatus of the present invention can also be configured by a single ultrasonic atomization chamber including one ultrasonic transducer and a cylindrical body. This atomization device can be effectively used as a humidifier, for example.

  In the atomizing apparatus 1 described above, the ultrasonic transducer 2 is disposed upward below the cylindrical body 6, and ultrasonic waves are emitted upward from the ultrasonic transducer 2 toward the inside of the cylindrical body 6. Thus, the solution inside the cylinder is ultrasonically vibrated. However, the atomization apparatus of the present invention does not specify the structure in which the ultrasonic transducer is disposed below the cylindrical body. As shown in FIG. 13, the atomizing device of the present invention can be provided with the ultrasonic vibrator 2 so as to protrude from the extrusion port 12 of the cylindrical body 6 into the gas. The ultrasonic transducer 2 shown in this figure has a structure that radiates ultrasonic waves in a direction perpendicular to surfaces facing each other. Further, the atomizing device 1 is configured to inject the solution from the extrusion port 12 of the cylindrical body 6 in a column shape by the pressure mechanism 5. The atomizing device 1 jets the solution supplied to the cylindrical body 6 upward from the extrusion port 12 to generate a liquid column protruding upward, and in this state, the super column disposed inside the liquid column. An ultrasonic wave is radiated from the inside of the liquid column toward both sides by the sonic vibrator 2 to atomize the solution into a mist in the gas. As shown in the figure, the ultrasonic transducer 2 is disposed inside a columnar solution ejected from the extrusion port 12 of the cylindrical body 6. In other words, the solution is ejected by the pressure mechanism 5 so that a liquid column is formed around the ultrasonic vibrator 2. Since the atomizing device 1 having this structure can radiate ultrasonic vibrations radiated from the ultrasonic transducer 2 in both the left and right directions in the figure, it has the advantage that it can be efficiently atomized into mist on both sides of the columnar solution. .

  The atomizing device 1 described above atomizes the solution in the ultrasonic atomizing chamber 4 ultrasonically by the ultrasonic vibrator 2 and atomizes it into mist. The mist atomized by the atomizer 1 has a higher concentration of the target substance than the solution. Therefore, a high-concentration solution can be efficiently separated by atomizing the solution into mist with the atomizer 1 and aggregating and collecting the mist.

  The mist of the solution atomized by the atomizing device 1 flows into the collection unit 40 via the carrier gas and is collected by the collection unit 40. In order to cause the mist to flow into the recovery unit 40, the separation device of FIGS. 2 to 5 connects the recovery unit 40 to the atomization device 1 by a duct 41. In the separation apparatus of FIGS. 2, 4, and 5, the carrier gas is conveyed to the collection unit 40 by the blower 48. In the separation device shown in FIG. 3, the blower mechanism 8 of the pressure mechanism 5 is used in combination with a blower 48 for transferring the carrier gas. These separation devices convey the carrier gas containing mist from the atomization device 1 to the recovery unit 40. In particular, the separation devices shown in FIGS. 2, 4, and 5 circulate the carrier gas from which the mist component has been separated into the ultrasonic atomization chamber 4. This separation device can preferably use an inert gas such as nitrogen, helium, or argon as the carrier gas. In this separation device, alteration of the solution in the atomization device 1 and the recovery unit 40 is prevented by the inert gas. For this reason, a highly concentrated solution can be obtained in a higher quality state. However, air can also be used as the carrier gas.

  The collection unit 40 aggregates fine mist and collects it as a high-concentration alcohol solution. Since mist is not a gas, it can be aggregated and recovered without necessarily cooling. However, mist can be cooled and recovered quickly. The recovery unit 40 in FIGS. 2 to 4 incorporates a cooling heat exchanger 33 that cools and aggregates the mist. The cooling heat exchanger 33 has fins (not shown) fixed to the heat exchange pipe 34. The heat exchanger 33 is cooled by circulating a cooling refrigerant and cooling water through the heat exchange pipe 34. A part of the mist atomized in the ultrasonic atomizing chamber 4 is vaporized to become a gas, but the gas is cooled by the heat exchanger 33 of the recovery unit 40, condensed, condensed and recovered. The mist flowing into the recovery unit 40 collides with the heat exchanger 33 or collides with each other and largely agglomerates, collides with the fins of the heat exchanger 33 or the like and greatly agglomerates and is collected as a solution. The air collected by aggregating mist and gas in the heat exchanger 33 is circulated again to the ultrasonic atomization chamber 4 via the circulation duct 41.

  Further, although not shown, the recovery unit can also recover the target substance contained in the gas by adsorbing a vapor such as alcohol to the adsorbent. For example, the recovery unit can discharge the alcohol adsorbed on the adsorbent with the heated recovery gas, cool the recovery gas, and condense the recovered alcohol to recover. The recovery unit can be constituted by, for example, a rotor provided with an adsorbent in the gap and a rotation drive mechanism that rotates the rotor. The rotor is a honeycomb rotor having a gap through which gas can pass in the direction of the rotation axis. As the adsorbent, for example, zeolite, activated carbon, lithium oxide, silica gel, or a mixture thereof can be used. The recovery unit rotates the rotor at a predetermined speed with a rotation drive mechanism, and moves the rotor to an adsorption region where the vapor is adsorbed and a regeneration region where the adsorbed vapor is discharged. When the rotor is moved to the adsorption region, the gas containing the target substance alcohol vapor is passed through the gap, and the target substance alcohol contained in the gas is adsorbed by the adsorbent. When the rotor is rotated and moved to the regeneration area, the adsorbed target substance alcohol is discharged. The discharged target substance alcohol is recovered by cooling the recovery gas. The gas that has passed through the adsorption region of the rotor is moved again to the ultrasonic atomization chamber.

  In the separation device of the above embodiment, the atomization device 1 and the recovery unit 40 are separated separately and connected by a circulation duct 41. However, as shown in FIG. 14 to FIG. 17, the separation device can have the atomizing device 1 and the collection unit 40 as an integrated structure. 14 and 16 has the atomizer 1 built in the recovery unit 40, and the separators of FIGS. 15 and 17 constitute one airtight chamber with the recovery unit 40 and the atomizer 1. And the collection | recovery part 40 and the atomization apparatus 1 are connected integrally. 15 and 17 has an integral structure in which the ultrasonic atomization chamber 4 and the upper part of the collection unit 40 are connected via a connection duct 42 that is a communication path. The separation devices shown in these figures have a sufficiently large volume of the recovery unit 40 compared to the ultrasonic atomization chamber 4 of the atomization device 1, for example, 2 to 100 times the volume of the ultrasonic atomization chamber 4. , Preferably 5 to 50 times, more preferably 5 to 20 times. In the separation device shown in the figure, the mist atomized in the ultrasonic atomization chamber 4 is slowly lowered and recovered as a solution in the recovery unit 40.

  14 to 17 is a closed chamber, and the mist supplied thereto is not discharged to the outside. Therefore, the mists supplied to the collection unit 40 collide with each other and largely aggregate, or collide with a baffle plate or the like and greatly aggregate to be collected as a solution. In order to collect the mist more quickly in the collection unit 40, the collection unit 40 of FIGS. 14 and 15 includes a nozzle 36 for sprinkling the solution. The nozzle 36 is connected to the bottom of the collection unit 40 via the circulation pump 35. The circulation pump 35 sucks the solution collected in the collection unit 40 and sprays it from the nozzle 36.

  In the illustrated ultrasonic separating apparatus, nozzles 36 are disposed on the upper and side surfaces of the collection unit 40. The upper nozzle 36 sprays the solution downward. The side nozzles 36 spray the solution in the horizontal direction. The solution sprayed from the nozzle 36 is a sufficiently large water droplet as compared to the mist atomized by the atomizing device 1, and quickly falls inside the collecting unit 40. It collides with the mist floating inside and falls while collecting the mist. Therefore, the mist floating in the collection unit 40 can be collected efficiently and promptly.

  In the illustrated separating apparatus, the nozzles 36 are disposed on the upper side and the side surface, but the nozzles may be disposed on the lower part of the collection unit. The lower nozzle sprays the solution upward. The nozzle sprays the solution at a speed at which the solution collides with the ceiling of the recovery unit 40 or at a speed that rises to the vicinity of the ceiling. Since the solution sprayed so as to rise to the vicinity of the ceiling changes its direction downward in the vicinity of the ceiling and falls, it comes into contact with the mist when it rises and descends and efficiently collects the mist.

  Further, the collection unit 40 of FIG. 16 has a plurality of baffle plates 37 disposed therein. The baffle plate 37 is arranged in a vertical posture with a gap through which mist can pass between adjacent baffle plates. The vertical baffle plate 37 can recover the adhering solution by letting the mist collide with the surface and let it flow naturally. The baffle plate 37 shown in the figure has a concavo-convex surface so that mist can be contacted more efficiently and recovered.

  Further, the recovery unit 40 of FIG. 16 is provided with a fan 38 that forcibly blows and agitates mist. The fan 38 agitates the mist of the collection unit 40. The agitated mists collide with each other and aggregate or collide with the surface of the baffle plate 37. Aggregating mist is quickly dropped and collected. The illustrated fan 38 blows and circulates the mist of the collection unit 40 downward.

  The ultrasonic separating apparatus of FIG. 17 is provided with a mist vibrator 39 in the recovery unit 40 that increases the probability that the mists vibrate and collide with each other. The mist vibrator 39 includes an electric vibration-mechanical vibration converter that vibrates the gas in the collection unit 40 and a vibration power source that drives the electric vibration-mechanical vibration converter. The electric vibration-mechanical vibration converter is a speaker that emits sound having an audible frequency, an ultrasonic vibrator that emits ultrasonic waves higher than the audible frequency, or the like. In order for the electric vibration-mechanical vibration converter to vibrate the mist efficiently, the recovery unit 40 resonates the vibration radiated from the electric vibration-mechanical vibration converter. In order to realize this, the electric vibration-mechanical vibration converter is vibrated at a frequency that resonates in the recovery unit 40. In other words, the recovery unit 40 is designed to resonate with the vibration radiated from the electric vibration-mechanical vibration converter.

  Ultrasound is a high frequency that exceeds the human audible frequency, so it cannot be heard by the ear. For this reason, the mist vibrator 39 that radiates ultrasonic waves vibrates the gas in the recovery unit 40 violently. In other words, the output of the electrical vibration-mechanical vibration converter is extremely increased, causing sound harm to humans. There is nothing. For this reason, ultrasonic waves have the feature that they can be recovered quickly by vigorously causing mist to vibrate.

  In the above separating apparatus, a device for efficiently aggregating mist is disposed in the recovery unit 40, so that the mist can be agglomerated more quickly to obtain a high-concentration solution. Further, although not shown, the solution separation apparatus can aggregate the mist most efficiently by incorporating all of the nozzle for spraying the solution, the fan for stirring the mist, and the vibrator for vibrating the mist in the recovery unit. . Also, two devices for aggregating mist can be incorporated to efficiently agglomerate mist.

  The ultrasonic atomization chamber 4 and the collection unit 40 are preferably filled with an inert gas. In this apparatus, alteration of the solution in the ultrasonic atomization chamber 4 and the recovery unit 40 is prevented by the inert gas. For this reason, a highly concentrated solution can be obtained in a higher quality state.
