However, the collection efficiency of suspended solids by these methods is not always sufficient, and the suspended solids cannot be recovered properly. In addition, the device tends to be large.
The present invention has been made in view of such problems, and is a compact separation apparatus that can efficiently separate suspended substances from a gas, and is compact and included in a liquid to be treated. It is an object of the present invention to provide a liquid fractionating device capable of efficiently fractionating existing components.

  The solution is a separation device that agglomerates floating substances suspended in a gas and separates them from the gas, and includes a tube member having a tube through-hole through which the gas containing the suspended substance flows, and the tube member An ultrasonic vibration source that surrounds at least a portion of the tube length direction of the tube and vibrates the tube member, and at least a part of the tube member is surrounded by the ultrasonic vibration source. And an ultrasonic vibration generating source that generates ultrasonic vibration and forms an in-tube standing wave sound field in the pipe through-hole by aerial ultrasonic waves radiated from the pipe member.

The separation device of the present invention includes a tube member and an ultrasonic vibration generation source. The ultrasonic vibration generation source surrounds at least a part of the tube member in the tube length direction and vibrates the tube member. Then, ultrasonic vibration is generated in at least a part of the portion surrounded by the ultrasonic vibration generating source to form an in-tube standing wave sound field in the through-hole.
As a result, suspended substances such as mist-like droplets and smoke introduced into the tube through-holes gather at the nodes of the standing wave sound field, and the suspended substances collide with each other and gradually become larger particles. Become. Then, it cannot float in the air, falls according to gravity, adheres to the inner peripheral surface of the gutter member, or falls into a separate collection container.
The aerial ultrasonic wave attenuates abruptly as it progresses in the air. However, in the separation device of the present invention, the side wall is ultrasonically vibrated, and the aerial ultrasonic wave is emitted from the side wall, so that In the internal circulation space, airborne ultrasonic waves can be applied to the suspended matter suspended in the gas in the immediate vicinity of the side wall to vibrate, so that the suspended matter can be efficiently aggregated.

Thus, in the separation device of the present invention, gas and suspended solids can be efficiently separated.
Moreover, in the separation device of the present invention, the ultrasonic vibration generation source is arranged so as to surround at least a part of the pipe member in the pipe length direction in the radial direction. Therefore, it becomes a compact separation device.

  In addition, since the separation apparatus of the present invention is compact, it can be used to separate floating substances flowing in the pipe by replacing a part of the existing pipe with the separation apparatus of the present invention. .

  The separation device of the present invention collects suspended solids from a gas and obtains a useful liquid or other material, that is, is used as a liquid recovery device or a material recovery device. When it is desired to obtain a gas free of air, that is, it can be used as a suspended substance removing device.

  Examples of suspended substances include particulate substances that float in a gas and can be integrated and enlarged by colliding with each other. For example, droplets such as mist-like water drops, oil drops, and cigarette smoke And α particles contained in exhaust gas and the like. Further, the mist-like droplet may be any droplet as long as it is desired to recover the droplet as a liquid or to be removed from the gas, for example, water, alcohol, water and alcohol. Liquid droplets such as water containing a mixed liquid, metal ions, an organic solvent, and oil can be used.

  Any ultrasonic vibration source may be used as long as it generates ultrasonic vibration in a form surrounding the circumference of the pipe member, and a cylindrical superstructure using a piezoelectric element, a magnetostrictive element, or the like. A sound wave vibrator is mentioned. In particular, in order to generate strong ultrasonic vibration, a bolt-clamped Langevin type ultrasonic vibrator using a cylindrical bolt member may be used. A cylindrical bolt member can also be used as the tube member in the present invention.

In addition, as a pipe member, a material or the like may be selected in consideration of a gas or a floating substance to be used, ease of processing, difficulty in attenuation of ultrasonic vibration, and the like. It is preferable to use metals such as alumina and ceramics such as alumina.
Further, as the pipe member, a straight straight pipe can be used, and it is only necessary that the ultrasonic vibration generation source can be arranged in a form surrounding the circumference in the radial direction of the pipe member, and it may be bent or further spiral. .
As a standing wave sound field formed in the pipe through-hole of the pipe member, a large part (corresponding to the abdomen) and a small part (corresponding to the node part) of ultrasonic vibration are formed in the pipe through-hole. It is sufficient that the amplitude of the ultrasonic vibration is not completely eliminated even in a small vibration portion. In general, suspended substances gather in a portion (node) where vibration is small, and aggregation is likely to occur in this portion.
In the case where the suspended substance is a mist-like droplet, the liquid can be efficiently recovered by collecting the liquid through the liquid flow path after the droplet adheres to the inner peripheral surface of the tube member and liquefies. For example, there is a method in which the liquid is moved along the inner peripheral surface of the pipe member by tilting the pipe member from the horizontal or parallel to the vertical line.

  Furthermore, in the above separation device, a pipe member having a pipe through hole, the pipe through hole communicating with the pipe through hole on one side of the ultrasonic vibration generation source in the tube length direction The ultrasonic vibration generation source generates ultrasonic vibrations in the pipe member, and a standing wave sound field in the pipe is formed in the pipe through-hole by aerial ultrasonic waves radiated from the pipe member. A separation device including a pipe member is preferable.

  In the separation device of the present invention, a pipe member is provided in addition to a pipe member and an ultrasonic vibration generation source. Also in this pipe member, ultrasonic vibration is generated by the ultrasonic vibration generation source, and the pipe is fixed in the pipe through hole. A wave field is formed. Therefore, since the gas and the suspended substance can be separated not only in the pipe member but also in the pipe member, the suspended substance can be more efficiently separated from the gas.

The pipe member may also be selected in consideration of the gas or suspended material to be used, the ease of processing, the difficulty of attenuation of ultrasonic vibration, etc., for example, stainless steel with high acoustic impedance, etc. It is preferable to use ceramics such as metals and alumina.
In the pipe standing wave sound field formed in the pipe through-hole of the pipe member, the large part (corresponding to the abdomen) of the vibration of the air ultrasonic wave and the small part (node) in the pipe through-hole are the same as in the pipe standing wave sound field. And the amplitude of the ultrasonic vibration is not necessarily completely eliminated even in a small vibration portion.
When the suspended substance is a mist-like droplet, the inner peripheral surface of the pipe member may be inclined with respect to the horizontal, and the liquid adhering to the inner peripheral surface may be moved along the inner peripheral surface.

  Further, in the separation device according to claim 2, the pipe member may be a separation device having a form in which a dimension in a pipe length direction is longer than a dimension in a radial direction.

  In the separation device of the present invention, the pipe member is in the form of a pipe having a pipe length longer than the diameter. For this reason, the intensity of the aerial ultrasonic wave that is radiated from the pipe member into the pipe through-hole and easily attenuates does not increase so much if the radial dimension of the pipe is small. In addition, suspended substances such as mist droplets can be passed through the standing wave sound field in the pipe member over a long distance in the tube length direction. For this reason, more suspended solids can be aggregated and efficiently separated from the gas.

  Alternatively, in the separation device according to claim 1, the tube member is a one-side protruding portion that protrudes to one side in the tube length direction from the ultrasonic vibration generation source, and the ultrasonic vibration generation The ultrasonic vibration is generated in the one side protruding portion by the source, the one side protruding portion in which the protruding portion standing wave sound field is formed in the tube through hole in the one side protruding portion, and the ultrasonic vibration generating source. The other side protruding portion protruding to the other side in the tube length direction, the ultrasonic vibration generating source generates ultrasonic vibration in the other side protruding portion, and the inside of the tube through hole in the other side protruding portion. It is preferable that the separation device has at least one of the other-side protruding portion where the in-projecting standing wave sound field is formed.

In the separation device of the present invention, the tube member has at least one of a one-side protruding portion and an other-side protruding portion in which a standing-wave standing-wave sound field is formed. That is, the tube member forms an in-tube standing wave sound field in the tube through-hole, and an in-projection standing wave sound field is formed in at least one of the one side protrusion and the other side protrusion. For this reason, since the gas and the suspended solid can be separated not only in the standing wave acoustic field in the tube but also in the standing standing acoustic field, the suspended matter can be more efficiently separated from the gas.
Moreover, in the separation device of the present invention, since the pipe member has at least one of the one side protruding portion and the other side protruding portion, there is no need to prepare a pipe member or attach it separately, and handling is easy. It is.

  In addition, the standing wave sound field in the protruding part formed in the pipe through hole in the one side protruding part of the pipe member and in the pipe through hole in the other side protruding part is also the same as the in-pipe standing wave sound field. It is only necessary to form a large vibration portion (corresponding to the abdomen) and a small portion (corresponding to the node portion), and the amplitude of the ultrasonic vibration is not necessarily completely eliminated even in the small vibration portion.

  Still another solution is a separation device that agglomerates floating substances suspended in a gas and separates them from the gas, and includes a bolt-clamped Langevin vibrator, and among the bolt-clamped Langevin vibrators, a bolt member Is a cylindrical bolt member including a bolt through-hole penetrating itself along the axis of the bolt-tightened Langevin vibrator, and the bolt-tightened Langevin vibrator includes at least the bolt through-hole, It is a separation device having a through-flow hole penetrating along the axis and through which a gas containing the suspended substance flows.

The separation device of the present invention includes a bolt-tightened Langevin type vibrator in which the bolt is a cylindrical bolt member. When the bolted Langevin type vibrator is driven at a predetermined frequency, vibration that expands and contracts in the axial direction (the tube length direction of the cylindrical bolt member) is generated.
By the way, in general, a bolt-clamped Langevin type vibrator sandwiches an annular element that generates vibration, such as a piezoelectric element and a magnetostrictive element, between two members, and is fastened to each other by a bolt member or a bolt member and a nut member that are inserted through these elements. The element is compressed by two members. Therefore, the bolt member is engaged with two members that sandwich the element directly or via a nut member, and tensile stress is applied to the bolt member.

Accordingly, when the bolted Langevin type vibrator expands and contracts in the axial direction, the cylindrical bolt member expands and contracts in the bolt tightened Langevin type vibrator. Along with this, the inner wall surface of the cylindrical bolt generates respiratory vibrations whose diameter increases and decreases in the radial direction orthogonal to the axis. Due to this breathing vibration, in the bolt through hole in the cylindrical bolt, aerial ultrasonic waves are emitted from the inner wall surface toward the axis, and the ultrasonic waves are concentrated toward the axis.
Accordingly, a standing wave sound field within the bolt is formed at least in the internal space of the through hole of the through hole. For this reason, when floating substances such as mist-like droplets are introduced into the through-flow holes, the floating substances gather at the nodes of the standing wave sound field in the bolt, and the floating substances collide with each other and gradually integrate. Large particles. Then, it cannot float in the air, falls according to gravity, and adheres to the inner peripheral surface or the like of the bolt through hole. Thus, suspended solids can be separated from the gas.
In addition, since the bolt through hole of the cylindrical bolt member of the bolted Langevin type vibrator is included in the through circulation hole, a compact separation device is obtained. Moreover, since a strong standing wave sound field in the bolt can be formed in the bolt through-hole, suspended matter can be recovered with high efficiency.

  If the axis of the bolted Langevin type ultrasonic transducer is tilted from the horizontal or held vertically, an appropriate liquid flow path or floating substance discharge path can be configured. Can be efficiently recovered.

  Furthermore, it is a separation apparatus of Claim 4, Comprising: It is a pipe member provided with a pipe through-hole, Comprising: The said pipe through-hole was connected with the said through-flow hole at the one end of the said bolt fastening Langevin type vibrator. The pipe-clamped Langevin type vibrator generates ultrasonic vibrations in the pipe member, and a standing wave sound field in the pipe is formed in the pipe through-hole by the aerial ultrasonic wave radiated from the pipe member. It is good to set it as the separation apparatus provided with the pipe member made.

  In the separation device of the present invention, a bolt-clamped Langevin type vibrator is provided, and a pipe member having a pipe through hole is fixed to one end thereof. Also in this pipe member, ultrasonic vibration is generated by the bolted Langevin type vibrator, and a standing wave sound field in the pipe is formed in the pipe through hole. Therefore, since the gas and the floating substance can be separated not only in the bolt through hole of the cylindrical bolt member but also in the pipe member, the floating substance can be more efficiently separated from the gas.

In addition, it is preferable that a pipe member has a form with a long pipe length direction dimension with respect to a radial direction dimension.
If the pipe member is in the form of a tube that is long compared to its diameter, the intensity of the aerial ultrasonic wave that is radiated from the pipe member into the pipe through-hole and easily attenuates will be too great if the radial dimension of the pipe is small. Don't be. In addition, suspended substances such as mist droplets can be passed through the standing wave sound field in the pipe member over a long distance in the tube length direction. For this reason, more suspended solids can be aggregated and efficiently separated from the gas.

  Alternatively, in the separation device according to claim 4, the cylindrical bolt member is a one-side protruding portion that protrudes to one side of the axis line relative to the bolt-tightened Langevin type vibrator, A one-side protruding portion in which a standing wave sound field is formed in the bolt through hole in the one-side protruding portion by the ultrasonic vibration generated in the one-side protruding portion by the Langevin-type vibrator, and the bolt-tightened Langevin The other side protruding portion that protrudes to the other side of the axis than the type vibrator, and the bolt tightening Langevin type vibrator generates ultrasonic vibration in the other side protruding portion, and the bolt in the other side protruding portion It is preferable that the separation device has at least one of the other protruding portion in which the standing wave sound field in the protruding portion is formed in the through hole.

In the separation device of the present invention, the cylindrical bolt member of the bolted Langevin type vibrator is itself, that is, the one-side protruding portion that projects to one side of the axis than the bolted Langevin type vibrator excluding the cylindrical bolt member. And it has at least any one of the other side protrusion parts which protrude in the other side of an axis rather than the bolt fastening Langevin type vibrator except a cylindrical bolt member. In addition, a protruding portion standing wave sound field is formed in the bolt through holes in the one side protruding portion and the other side protruding portion.
Thus, not only respiratory vibration accompanying expansion and contraction of the cylindrical bolt member in the bolt-tightened Langevin type vibrator, but also at least one of the one side projecting portion and the other side projecting portion is projected into the bolt through hole. Since an internal standing wave sound field is formed, suspended material can be separated from the gas even in this portion. Therefore, it is compact and can collect suspended solids with higher efficiency.

  Yet another solution is a separation device that agglomerates floating substances suspended in a gas and separates them from the gas, and is a plurality of annular piezoelectric elements having element through-holes, A plurality of piezoelectric elements arranged coaxially, an electrode plate interposed between the piezoelectric elements, and a first through hole that is located closer to the base end side of the element axis than the plurality of piezoelectric elements and extends along the element axis A first annular member having a ring shape, a second annular member having a second through-hole located on the tip side of the element axis with respect to the plurality of piezoelectric elements and having a second through hole along the element axis, and the element axis. A cylindrical cylindrical bolt member having a bolt through-hole penetrating along the element and projecting toward the base end side of the element axis from the first annular member, and in the element through-hole of the piezoelectric element and in the first annular Pass through the first through hole of the member, At least a first screw portion that extends into the second through-hole of the second annular member and is formed at a protruding portion that protrudes at least to the base end side of the element axis from the first annular member; and A cylindrical bolt member including a second screw portion fastened to the second annular member in the second through hole, and abuts on the first annular member from the base end side of the element axis rather than the first annular member. A nut member, wherein the first annular member and the second annular member compress a plurality of the piezoelectric elements in a direction along the element axis, and the first screw portion of the cylindrical bolt member and the first annular member. And a nut member that is fastened to the first screw portion of the cylindrical bolt member by generating a tensile stress between the two screw portions.

In the separation device of the present invention, in addition to the piezoelectric element, the first annular member, and the second annular member, the cylindrical bolt member is also provided with a through hole along the direction of the element axis.
In addition, when a driving voltage having a predetermined frequency is applied to the piezoelectric element, ultrasonic vibration is generated in the first annular member, the second annular member, and the cylindrical bolt member due to the vibration in the axial direction generated in the piezoelectric element. At this time, the cylindrical bolt member expands and contracts, and also generates a breathing vibration-like ultrasonic vibration in which the diameter of the bolt through hole expands and contracts in the radial direction orthogonal to the axis. Due to the ultrasonic vibration excited by the cylindrical bolt member, an in-bolt standing wave sound field is formed in the bolt through-hole by aerial ultrasonic waves radiated from the wall of the bolt through-hole toward the inside (axis).
Therefore, if a gas containing floating substances such as mist droplets is introduced into the bolt through holes, the floating substances collect at the nodes of the standing wave sound field in the bolt and the floating substances collide with each other. And gradually become larger particles. Then, it cannot float in the air, falls according to gravity, and adheres to the inner peripheral surface or the like of the cylindrical bolt member. Thus, suspended solids can be separated from the gas.
Further, since the piezoelectric element or the like is arranged around the radial direction of the cylindrical bolt member, a compact separation device is obtained. Moreover, since a strong standing wave sound field in the bolt can be formed in the bolt through-hole, suspended matter can be recovered with high efficiency.

  In addition, if the cylindrical bolt member is inclined from the horizontal or in a vertical state, and an appropriate liquid flow path or floating substance discharge path is configured, the floating substance can be efficiently recovered. it can.

  Furthermore, it is a separation apparatus of Claim 7, Comprising: It is a pipe member provided with a pipe through-hole, Comprising: The said pipe through-hole was connected with the said 2nd through-hole at the said front end side of a said 2nd annular member. The ultrasonic vibration generated in the pipe member by the ultrasonic vibration generated by driving the piezoelectric element is fixed in a state, and the constant vibration is generated in the pipe through-hole by the aerial ultrasonic wave radiated from the pipe member. It is preferable that the separation device includes a pipe member in which a standing wave field is formed.

  In this separation device, the pipe member fixing provided with the pipe through hole is fixed to the distal end side of the second annular member. Also in this pipe member, an in-pipe standing wave sound field is formed in the pipe through hole by ultrasonic vibration. Therefore, since the gas and the floating substance can be separated not only in the bolt through hole of the cylindrical bolt member but also in the pipe member, the floating substance can be more efficiently separated from the gas.

In addition, it is preferable that a pipe member has a form with a long pipe length direction dimension with respect to a radial direction dimension.
If the pipe member is in the form of a tube that is long compared to its diameter, the intensity of the aerial ultrasonic wave that is radiated from the pipe member into the pipe through-hole and easily attenuates will be too great if the radial dimension of the pipe is small. Don't be. In addition, suspended substances such as mist droplets can be passed through the standing wave sound field in the pipe member over a long distance in the tube length direction. For this reason, more suspended solids can be aggregated and efficiently separated from the gas.

  Alternatively, the separation device according to claim 7, wherein the cylindrical bolt member is a proximal-side protruding portion that protrudes toward the proximal end side of the element axis line with respect to the first annular member, and is the piezoelectric device. By driving the element, ultrasonic vibration is generated in the proximal-side protruding portion, and the standing-side protruding portion in which the standing wave sound field is formed in the bolt through hole in the proximal-side protruding portion, and the second A tip-side protruding portion that protrudes to the tip side of the element axis rather than the annular member, and generates ultrasonic vibration in the tip-side protruding portion by driving the piezoelectric element, and the bolt through hole in the tip-side protruding portion It is preferable that the separation device has at least one of a tip-side protruding portion in which the standing wave sound field is formed.

In this separation device, the cylindrical bolt member is at least one of a proximal end protruding portion that protrudes more proximally than the first annular member and a distal end protruding portion that protrudes more distally than the second annular member. Have In addition, a protruding portion standing wave sound field is formed in the bolt through-holes in the proximal-side protruding portion and the distal-side protruding portion.
As described above, in this separation device, not only respiratory vibration accompanying expansion and contraction of the cylindrical bolt member, but also at least one of the proximal-side protruding portion and the distal-side protruding portion is fixed in the protruding portion in the bolt through hole. Since a wave sound field is formed, suspended matter can be separated from the gas even in this part. Therefore, it is compact and can collect suspended solids with higher efficiency.

  Still another solving means is an ultrasonic atomizing means for atomizing a liquid to be treated by ultrasonic vibration to release a mist-like liquid droplet that is the suspended substance, and any one of claims 1 to 7. And a separation apparatus according to the item.

In the liquid fractionating device of the present invention, the liquid to be treated is atomized by ultrasonic vibration to discharge mist-like droplets. In general, when the liquid to be treated is atomized by ultrasonic vibration, for example, a relatively light specific component (alcohol) and a relatively specific gravity component (water) contained in the liquid to be treated, such as a mixture of water and alcohol. It has been found that a component having a relatively low specific gravity is scattered as a relatively small droplet (mist), or that there are a component that is likely to be scattered as a droplet and a component that is difficult to be scattered.
Therefore, if the liquid obtained by appropriately collecting the mist-like droplets (floating material) generated by the ultrasonic atomizing means, the concentration of the desired component from the separation device is relatively higher than the liquid to be treated. A liquid to be processed or a liquid to be processed in which the concentration of a desired component is higher than that of the original liquid to be processed is obtained in an ultrasonic atomizer.

In addition, as a substance that can be fractionated in this way, due to the difference in specific gravity of the components, the component ratio in the droplet (mist) is different from the component ratio in the liquid to be treated due to atomization by ultrasonic vibration. It only has to be a thing.
For example, by atomizing a mixed solution of water and ethyl alcohol (such as liquor, moromi, fermented liquid), a mixed solution of water and alcohol with an increased alcohol concentration can be obtained from the separation device. Moreover, the liquid mixture which raised the density | concentration of the organic solvent can be obtained from the separator by atomizing the wastewater containing an organic solvent. Moreover, alcohol which melt | dissolved fragrance components, such as citrus fruits, is atomized, and while recovering alcohol with a separator, the alcohol by which the density | concentration of the fragrance component was concentrated from an ultrasonic atomizer can be obtained. Further, by atomizing an aqueous solution containing a scent component such as soy sauce or an amino acid, an aqueous solution in which different components are concentrated can be obtained from the ultrasonic atomizing means and the separation device. Alternatively, by atomizing an aqueous solution containing heavy metal ions and light metal ions, the ultrasonic atomizing means provides an aqueous solution enriched with heavy metal ions, and from the separation device an aqueous solution enriched with light metal ions. Can be obtained.

In the above-described liquid fractionating device, it is preferable to use a liquid fractionating device in which the gas discharged from the discharge port of the separation device is returned to the ultrasonic atomizing means.
In this liquid fractionator, the gas flow in the entire liquid fractionator is a closed circuit, so that water vapor contained in the gas, vapor of each component, mist that could not be recovered, etc. are released to the outside air. The desired component can be separated from the liquid to be treated more appropriately.

  Embodiments of a separation apparatus and a liquid fractionation apparatus using the same according to the present invention will be described with reference to the drawings.

  A liquid fractionator and a separator according to an embodiment will be described with reference to FIGS. FIG. 1 is an explanatory diagram showing the overall configuration of the liquid fractionating device 100 according to the present embodiment. FIG. 2 is an explanatory diagram illustrating a schematic configuration of the separation device 120 according to the present embodiment. FIG. 3 is an explanatory diagram illustrating the structure of the separation device 120 according to the present embodiment.

  First, the liquid fractionating device 100 of the present embodiment will be described. The liquid fractionating device 100 according to the present embodiment is a device that obtains a treated liquid LQ2 and a liquefied recovery liquid LQ3 by fractionating the liquid LQ1 to be treated. For example, when a mixed liquid of water and ethyl alcohol (such as liquor or moromi) is used as the liquid LQ1, the liquid LQ2 that has been processed with a relatively low ethyl alcohol concentration and the liquid recovery liquid that has a relatively high ethyl alcohol concentration. Distill into LQ3.

As shown in FIG. 1, the liquid fractionating device 100 mainly includes an ultrasonic atomizing device 10 and a separation device 120. The ultrasonic atomizer 10 pumps the liquid container 11 to be treated, the ultrasonic vibrator 12 for atomization installed at the bottom, the atomization drive circuit 13 that drives the ultrasonic vibrator 12, and the mist MI in the liquid container 11 to be treated. A pressure-feeding fan 14.
In the ultrasonic atomizing device 10, the ultrasonic transducer 12 for atomization installed at the bottom of the liquid container 11 to be processed is added to the liquid LQ <b> 1 to be processed which is supplied from the liquid inlet 11 a of the liquid container 11 to be processed. Apply ultrasonic vibration from. Then, in the liquid LQ1, the portion irradiated with the ultrasonic waves rises like a fountain, and the tip portion thereof is subdivided by the ultrasonic waves to form a mist MI that is a mist-like droplet. The mist MI is discharged from the mist discharge port 11b together with the air by the air flow generated by the pressure feeding fan 14. The liquid container 11 also includes a liquid discharge port 11c for discharging the processed liquid LQ2.

The mist MI is sent to the separation device 120 described below, where it is liquefied and recovered as a liquefied recovered liquid LQ3.
However, if necessary, as shown by a broken line in FIG. 1, a pretreatment device WD may be arranged in front of the separation device 120. For example, in the case of distilling a mixture of water and ethyl alcohol, when the mist MI is generated by the ultrasonic atomizer 10, in general, ethyl alcohol having a low specific gravity has a relatively small particle diameter (for example, It is easy to become a mist (about φ0.3 μm). On the other hand, water with a high specific gravity tends to be a mist or droplet having a large particle diameter (for example, about φ3 μm). Therefore, it is preferable to remove mist and droplets having a large particle diameter in the pretreatment device WD. For example, as a pretreatment device WD, specifically, a large space is provided between the inlet and the outlet, and a particle sorting chamber for sorting light (small diameter) particles by using sedimentation of large particles in the air. A wire demister that passes through a metal mesh or a large number of metal fibers can be provided. The liquid removed and recovered by these may be discarded or returned to the liquid container 11 to be processed. In addition, before being sent to the separation device 120 as necessary, the air and mist MI are cooled without using the device for removing the large mist described above as the pretreatment device WD, or together with them, and the separation device 120 is used. It is also possible to provide a cooler to aid in agglomeration.

  The separation device 120 collects and liquefies the mist MI suspended in the gas (air in this embodiment), and separates the mist MI from the gas (air). As shown in FIGS. 2 and 3, the separation device 120 of the present embodiment includes a bolted Langevin type vibrator (hereinafter also simply referred to as a vibrator) 140 and a tip thereof (right side in FIG. 3A). The pipe member 130 is fixed, has an inlet 120N and an outlet 120T, and has a ventilation through hole 120I that penetrates the vibrator 140 and the pipe member 130.

  Among these, the vibrator 140 has a known bolt-clamped Langevin type ultrasonic vibrator structure except that a cylindrical bolt member 147 is used as a bolt. Specifically, a plurality of (four in this example) annular piezoelectric elements 142 polarized in the thickness direction and an electrode plate 143 sandwiched between them are cylindrically inserted through these elements. The bolt member 147 and the nut 146 are sandwiched between the front plate 144 and the backing plate 145 made of a metal material such as stainless steel.

  Specifically, in the vibrator 140, a bolt fastening screw portion 144SC1 formed in the front plate through hole 144H of the front plate 144 and a second screw portion 147SC2 formed in the tip portion of the cylindrical bolt member 147 are fastened. . In addition, the four piezoelectric elements 142 and the electrode plate 143 are stacked so that the element axis 142AX of the piezoelectric element 142 coincides with the axis 140AX, and these are sandwiched between the front plate 144 and the backing plate 145, and inside thereof A cylindrical bolt member 147 is inserted. Furthermore, among the cylindrical bolt members 147, a first screw portion 147SC1 provided on the base end side and protruding to the base end side (left side in FIG. 3) from the backing plate 145, and a screw portion 146SC of the nut 146, The cylindrical bolt member 147 and the nut 146 are fastened so that the piezoelectric element 142 is subjected to compressive stress in the direction of the axis 140AX. In addition, tensile stress is applied to the intermediate portion 147M between the first screw portion 147SC1 and the second screw portion 147SC2 in the cylindrical bolt member 147 in the direction of the axis 140AX.

  The cylindrical bolt member 147 has a bolt through hole 147I inside. Further, a front plate through hole 144H is formed in the front plate 144. Therefore, the vibrator 140 has a structure having an introduction port 140N on the proximal end side and a discharge port 140T on the distal end side and a vibrator through hole 140I along the axis 140AX. As shown in FIG. 2, the introduction port 140 </ b> N is also the introduction port 120 </ b> N of the separation device 120.

  A pipe member 130 made of stainless steel is fastened and fixed to the distal end side of the vibrator 140 (right side in FIG. 3A), that is, the distal end side of the front plate 144. This pipe member 130 is arranged coaxially with the axis 140AX, has a pipe through hole 130I that penetrates the inside, and has a distal end side (right side in FIG. 3) as a discharge port 130T and a proximal end side as an introduction port 130N. It is a cylindrical member. Therefore, the pipe through hole 130I is in a state of communicating with the front plate through hole 144H of the front plate 144, and thus with the vibrator through hole 140I of the vibrator 140, and with the bolt through hole 147I of the cylindrical bolt member 147. ing. As shown in FIG. 2, the discharge port 130 </ b> T is also a discharge port 120 </ b> T of the separation device 120.

  The pipe member 130 is a straight circular pipe-shaped pipe portion 131, and is located on the proximal end side (left side in FIG. 3A) of the pipe portion 131 and is larger in diameter than the pipe portion 131 and has a front plate 144. Fastened to fasten the pipe member 130 to the front plate 144 by screwing into the large-diameter contact portion 132 that comes into contact with the pipe member fastening screw portion 144SC2 formed at the front end portion of the front plate through hole 144H of the front plate 144. And a threaded portion 133SC.

  The vibrator 140 can generate ultrasonic vibration that expands and contracts in the direction of the axis 140AX by being driven at an appropriate frequency using the drive circuit PW (see FIG. 2). At this time, the cylindrical bolt member 147 is also expanded and contracted. Accordingly, in the cylindrical bolt member 147 (more specifically, the intermediate portion 147M), the inner peripheral surface 147S has a diameter perpendicular to the axis 140AX. In a direction (vertical direction in FIG. 3A), a respiratory vibration CU (see FIG. 3B) whose inner diameter expands and contracts is generated. For this reason, the aerial ultrasonic wave AU1 is radiated from the inner peripheral surface 147S toward the axis 140AX in the bolt through hole 147I. Then, an in-bolt standing wave sound field SS1 is formed in the bolt through hole 147I by the aerial ultrasonic wave AU1.

This in-bolt standing wave sound field SS1 includes, in the bolt through hole 147I of the cylindrical bolt member 147, a location (abdomen) where the aerial ultrasonic wave AU1 has a large amplitude and a location (node) where the amplitude is relatively small. It is out. This in-bolt standing wave sound field SS1 becomes a sound field in which nodes and abdomen are arranged on a concentric circle (concentric cylinder) as shown by a broken line in FIG. 3B due to the respiratory vibration CU centered on the axis 140AX.
In particular, in this embodiment, since the cylindrical bolt 147 is circular, the aerial ultrasonic wave AU1 can be concentrated toward the axis 140AX, so that a strong in-bolt standing wave sound field SS1 is formed in the vicinity of the axis 140AX. it can.

Further, the vibrator 140 vibrates the pipe member 130 through the front plate 144. For this reason, ultrasonic vibration also occurs in the pipe portion 131 of the pipe member 130. Specifically, a breathing vibration CU similar to the cylindrical bolt member 147 shown in FIG. 3B or a wall portion forming the pipe portion 131 as shown by a one-dot chain line and a broken line in FIG. A tube standing wave vibration BU that bends in the circumferential direction is generated. In any case, the aerial ultrasonic wave AU2 traveling toward the axis 140AX is radiated from the inner peripheral surface 131S of the pipe portion 131 by the respiratory vibration CU or the tube standing wave vibration BU generated in the pipe portion 131, and the pipe An in-pipe standing wave sound field SS2 is formed in the through-hole 130I by the aerial ultrasonic wave AU2.
In the present embodiment, since the pipe portion 131 has a circular tube shape, the aerial ultrasonic wave AU2 can be concentrated toward the axis 140AX, so that a strong in-pipe standing wave sound field SS2 can be formed in the vicinity of the axis 140AX.

Therefore, as shown in FIG. 2, the mist MI is introduced from the introduction port 120N (introduction port 140N) into the ventilation through hole 120I (specifically, the vibrator through hole 140I and the pipe through hole 130I) of the separation device 120. Air is blown using the mist nozzle 122 in the mist passage 121. Then, the mist MI is vibrated by the standing wave sound field SS1 in the bolt and the standing wave sound field SS2 in the pipe, and is collected at the node according to the principle of ultrasonic floating, and the mists MI collide with each other to be integrated with each other. The particle size of becomes larger. Then, it cannot float in the air against gravity and falls and adheres to the inner peripheral surface 147S of the cylindrical bolt member 147 and the inner peripheral surface 130S of the pipe member 130.
Thus, if the axis 140AX of the separation device 120 is tilted from the horizontal, the liquefied recovered liquid LQ3 obtained by liquefying the mist MI can be stored in the recovery container 124 from the inlet 120N or the outlet 120T.

Further, in the separation device 120 of this embodiment, as can be easily understood with reference to FIG. 3A, the length is LB in the direction of the axis 140AX as compared with the diameter D of the bolt through hole 147I. A long cylindrical bolt member 147 was used. In general, in the air, the aerial ultrasonic wave radiated from the inner peripheral surface 147S of the cylindrical bolt member 147 is attenuated rapidly as it progresses. However, in this embodiment, since the bolt through hole 147I having a small diameter is formed as compared with the length LB in the direction of the axis 140AX, the attenuation of the aerial ultrasonic wave AU1 in the bolt through hole 147I is small. Since the aerial ultrasonic wave AU1 can be applied to the mist MI that passes in the immediate vicinity of the peripheral surface 147S, the mist MI is greatly vibrated. For this reason, the mist MI can be efficiently aggregated and liquefied and recovered.
In addition, since the bolt through hole 147I has a length LB larger than the diameter D, the mist MI can be repeatedly irradiated with the aerial ultrasonic wave AU over a long distance in the axis 140AX direction. Mist MI can be collected.

The same applies to the pipe member 130. That is, as can be easily understood with reference to FIG. 3A, the pipe portion 131 of the pipe member 130 is straight and has a length LP in the direction of the axis 140AX as compared to the diameter DP of the pipe through-hole 130I. long. Therefore, the aerial ultrasonic wave AU2 radiated from the inner peripheral surface 1301S is less attenuated in the bolt through hole 147I, and the aerial ultrasonic wave AU2 can be irradiated to the mist MI passing through the immediate vicinity of the inner peripheral surface 131S. The mist MI is vibrated greatly. For this reason, the mist MI can be efficiently aggregated and liquefied and recovered.
In addition, since the pipe through-hole 130I has a length LP larger than the diameter DP, the mist MI can be repeatedly irradiated with the aerial ultrasonic wave AU2 over a long distance in the direction of the axis 140AX. Mist MI can be collected.

  Thus, in the separation device 120, the mist MI is efficiently recovered from the air (gas) containing the mist MI introduced into the ventilation through-hole 120I, and the air and the mist MI are separated and liquefied and recovered from the mist MI. The liquid LQ3 can be recovered.

  In addition, the separation device 120 of the present embodiment has a bolted Langevin type vibrator 140 formed by a piezoelectric element 142 or the like around a tubular cylindrical bolt member 147, and a pipe member on the tip side thereof. 130 is arranged. For this reason, it becomes a compact form compared with the separation apparatus of the machine structure in the case of collect | recovering mist MI by the cooling etc. which were mentioned above. Furthermore, not only in such a case, the separation device is compact even when compared with a separation device in which the tube member is separately ultrasonically vibrated by an ultrasonic vibrator from the outside.

  The air from which the mist MI has been separated by the separation device 120 is discharged from the discharge port 131T. The discharged air can be discharged to the outside air (outside), but in the liquid fractionating device 100 of this embodiment shown in FIG. 1, the ultrasonic atomizer is again fed by the pressure feed fan 14 through a passage not shown. A closed circuit 101 is configured to return to the ten liquid containers 11 to be processed. By using such a circulation type liquid fractionator 100, for example, alcohol contained in the air as vapor (gas) instead of mist or mist MI that could not be recovered is released to the outside air. Without being returned to the ultrasonic atomizer 10, and loss due to the emission can be reduced.

  In addition, as shown by the broken line in FIG. 1, the post-processing device HT can be arranged after the separation device 120 as necessary. For example, when the temperature of the air returned to the ultrasonic atomizer 10 is too low due to the use of a cooler as described above, a heater for heating the air can be provided in advance. Moreover, it can replace with a heater and can also heat air using the waste heat which arises from the cooler etc. which were used for the drive circuit PW, the atomization drive circuit 13 of the ultrasonic atomizer 10, and the pre-processing apparatus WD.

  Thus, in the liquid fractionating device 100 of this embodiment, in addition to the ultrasonic atomizing device 10, the cylindrical bolt member 147 of the vibrator 140 and the pipe portion 131 of the pipe member 130 are ultrasonically vibrated to liquefy the mist MI. Separation device 120 was used. For this reason, even when the mist MI is generated from the liquid LQ1 to be processed by the ultrasonic atomizer 10, it can be atomized by ultrasonic waves regardless of heat such as heating. In the separation device 120, the mist MI was condensed and liquefied by ultrasonic waves regardless of heating or cooling. Therefore, energy consumption due to heating and cooling is suppressed, and the liquid to be processed can be efficiently distilled. Furthermore, since not only the treated liquid LQ2 but also the liquefied recovery liquid LQ3 is less susceptible to thermal changes, the liquid LQ1 containing a component that easily breaks or deteriorates due to a thermal change such as a component constituting a flavor or aroma. Also when fractionating, it is possible to prevent alteration of the components.

In the first embodiment, the example in which the mist MI is aggregated in the separation device 120 to obtain the liquefied recovered liquid LQ3 is shown. However, the separation device 120 is not only the mist MI (droplet) of the first embodiment, but also smoke particles such as cigarettes, particles in automobile exhaust gas, and the like that can be aggregated into large particles by colliding with each other. Any particle can be separated from the air as long as the particles are included.
Further, in this embodiment, the mist MI is suspended in the air. However, in order to prevent alteration due to oxidation or the like, other gases such as an inert atmosphere such as nitrogen and other gases depending on the properties of the liquid to be processed LQ1 and the like are used. This can also be circulated.

(Modification)
Next, a modification of the above-described embodiment will be described with reference to FIG. In the separation device 120 of the liquid fractionating device 100 of the above-described embodiment, as shown in FIG. 3, the cylindrical bolt member 147 has a relatively short axial length, and the nut 146 is in the middle of the front plate 144. It was only up to length. For this reason, the pipe member 130 is provided on the tip side of the vibrator 140 separately from the vibrator 140.
On the other hand, the separation device 220 of the liquid fractionating device 200 of the present modification uses a cylindrical bolt member 247 having a long axial direction length that penetrates the bolted Langevin type vibrator 240 and does not include a pipe member. Different. Therefore, different parts will be described, and description of similar parts will be omitted or simplified.

  In the liquid fractionating device 200 of this modification, the ultrasonic atomizer 10, the pretreatment device WD, and the posttreatment device HT are the same as those in the first embodiment (see FIG. 1). Further, in the separation device 220 according to the present modification, the vibrator 240 includes a plurality of (four in this example) annular piezoelectric elements 142 polarized in the thickness direction and a gap between them as in the above-described embodiment. The electrode plate 143 sandwiched between the front plate 244 and the backing plate 145 is sandwiched between a cylindrical bolt member 247 and a nut 146 inserted inside the electrode plate 143.

However, the shape of the cylindrical bolt member 247 of the vibrator 240 is different from that of the embodiment, and as shown in FIG. 4A, it is longer in the direction of the axis 240AX and on the tip side than the front plate 244 (FIG. 4). It protrudes in (a), right side).
Specifically, in the vibrator 240, a bolt fastening screw portion 244SC formed in the front plate through hole 244H of the front plate 244 and a second screw portion 147SC2 formed in the middle portion of the cylindrical bolt member 247 are fastened. Yes. The four piezoelectric elements 142 and the electrode plate 143 are stacked so that the element axis 142AX of the piezoelectric element 142 coincides with the axis 240AX, and these are sandwiched between the front plate 244 and the backing plate 145, and inside thereof A cylindrical bolt member 247 is inserted. Further, among the cylindrical bolt member 247, a first screw portion 247SC1 provided on the base end side and protruding to the base end side (left side in FIG. 4) from the backing plate 145, and a screw portion 146SC of the nut 146, The cylindrical bolt member 247 and the nut 146 are fastened so that the piezoelectric element 142 is subjected to compressive stress in the direction of the axis 240AX.

  In the cylindrical bolt member 247, a tensile stress is applied to the intermediate portion 247M between the first screw portion 247SC1 and the second screw portion 247SC2 in the direction of the axis 240AX. Moreover, the cylindrical bolt member 247 has a front end side protruding portion 247P that protrudes from the front plate 244 to the front end side.

  The cylindrical bolt member 247 has a bolt through hole 247I inside. Therefore, the vibrator 240 has an introduction port 240N on the base end side, a discharge port 240T on the tip side, and a vibrator through hole 240I (bolt through hole 247I) along the axis 240AX. . As shown in FIG. 4, the introduction port 240 </ b> N, which is the proximal end of the cylindrical bolt member 247, also serves as the introduction port 220 </ b> N of the separation device 220. Further, the discharge port 240 </ b> T which is the end on the tip side of the cylindrical bolt member 247 is also a discharge port 220 </ b> T of the separation device 220.

  Also in this modified example, by driving the vibrator 240 at an appropriate frequency by the drive circuit PW (see FIG. 2), it is possible to generate ultrasonic vibration that expands and contracts in the direction of the axis 240AX. At this time, the intermediate portion 247M between the first screw portion 247SC1 and the second screw portion 247SC2 of the cylindrical bolt member 247 is also expanded and contracted. Accordingly, in the intermediate portion 247M of the cylindrical bolt member 247, the inner peripheral surface 247MS is expanded and contracted in the radial direction (vertical direction in FIG. 4A) perpendicular to the axis 240AX. A respiration vibration CU (see FIG. 4B) is generated. Therefore, in the bolt through hole 247I from the inner peripheral surface 247MS of the intermediate portion 247M, specifically, in the bolt through hole 247MI in the intermediate portion 247M, the aerial ultrasonic wave AU3 from the inner peripheral surface 247MS toward the axis 240AX. Is emitted. Then, an in-intermediate standing wave sound field SS3 is formed by the aerial ultrasonic wave AU3 in the bolt through hole 247MI in the intermediate portion 247M.

This intermediate part standing wave sound field SS3 includes a place (abdomen) where the amplitude of the aerial ultrasonic wave AU3 is large and a place (node part) where the amplitude is relatively small in the bolt through hole 247MI of the intermediate part 247M. Yes. This in-middle standing wave sound field SS3 becomes a sound field in which nodes and abdomen are arranged on a concentric circle (concentric cylinder) as shown by a broken line in FIG. 4B due to the respiratory vibration CU centered on the axis 240AX. .
In particular, in this modification, since the cylindrical bolt 247 is circular, the aerial ultrasonic wave AU3 can be concentrated toward the axis 240AX, so that a strong intermediate standing wave sound field SS3 is provided in the vicinity of the axis 240AX. Can be formed.

Furthermore, the vibrator 240 also vibrates the tip side protruding portion 247P of the cylindrical bolt member 247. For this reason, ultrasonic vibration is also generated in the tip side protruding portion 247P. Specifically, the respiratory vibration CU similar to that of the intermediate portion 247M shown in FIG. 4B, or the wall surface of the tip side protruding portion 247P is circumferential as shown by the alternate long and short dash line and broken line in FIG. The tube standing wave vibration BU is bent. In any case, the aerial ultrasonic wave AU4 traveling from the inner peripheral surface 247PS of the tip side protrusion 247P toward the axis 240AX is caused by the respiratory vibration CU or the tube standing wave vibration BU generated in the tip side protrusion 247P. The in-projection standing wave sound field SS4 is formed by the aerial ultrasonic wave AU4 in the bolt through hole 247PI of the tip side projection 247P.
In the present modification, since the tip side protruding portion 247P is also circular, the aerial ultrasonic wave AU4 can be concentrated toward the axis 240AX, so that a strong standing standing standing sound field SS4 is formed in the vicinity of the axis 240AX. it can.

  Therefore, the air containing the mist MI from the inlet 220N (introduction port 240N) into the ventilation through hole 220I (specifically, the vibrator through hole 240I and the bolt through hole 247I) of the separation device 220 of the present modification, It blows in using the mist nozzle 122 (refer FIG. 2) of the mist channel | path 121. FIG. Then, the mist MI is vibrated by the intermediate portion standing wave sound field SS3 and the protruding portion standing wave sound field SS4, and falls to adhere to the inner peripheral surface 247S of the cylindrical bolt member 247. Thus, the liquefied recovered liquid LQ3 obtained by liquefying the mist MI can be stored in the recovery container 124 from the separation device 220.

Further, in the separation device 220 of this modification, as can be easily understood with reference to FIG. 4A, the length is LB2 in the direction of the axis 240AX as compared with the diameter D of the bolt through hole 247I. A long cylindrical bolt member 247 was used. For this reason, also in the separation apparatus 220 of this modification, the mist MI can be efficiently aggregated, liquefied and recovered.
Moreover, since the bolt through-hole 247I has a length LB2 that is longer than the diameter D, the mist MI can be repeatedly irradiated with the aerial ultrasonic waves AU3 and AU4 over a long distance in the axis 240AX direction. The mist MI can be reliably recovered.

  Thus, also in this separation device 220, the mist MI is efficiently recovered from the air (gas) containing the mist MI introduced into the ventilation through hole 220I, and the air and the mist MI are separated and liquefied and recovered from the mist MI. The liquid LQ3 can be recovered.

  In addition, the separation device 220 according to the present modification has a bolted Langevin type vibrator 240 formed of a piezoelectric element 142 or the like around the cylindrical cylindrical bolt member 247, and the cylindrical bolt member 247. Is configured to protrude toward the tip side from the wash plate 244, and a tip side protruding portion 247P is provided. Similar to the separation device 120 of the above-described embodiment, it becomes a compact form as compared with the separation device having a mechanical configuration in which the mist MI is recovered by cooling or the like. Furthermore, not only in such a case, the separation device is compact even when compared with a separation device in which the tube member is separately ultrasonically vibrated by an ultrasonic vibrator from the outside.

  Furthermore, the separation device 120 of the above-described embodiment includes the pipe member 130 in addition to the vibrator 140. On the other hand, the separation device 220 of this modification does not require a pipe member and has a simpler configuration. Further, in the separation device 220 of this modification example, since one cylindrical bolt member 247 penetrates in the direction of the axis 240AX, the ventilation penetration 220I of the separation device 220 is formed on the inner periphery of the cylindrical bolt member 247. It is surrounded only by the surface 247S. Therefore, there are no joints or steps, and floating substances such as mist adhering to the inner peripheral surface 247S of the cylindrical bolt member 247 can be easily recovered, and cleaning and the like are easy.

  The air from which the mist MI has been separated by the separation device 220 is discharged from the discharge port 231T. As in the embodiment, the discharged air is returned to the ultrasonic atomizer 10 again through a passage (not shown) as shown in FIG. Thus, the separation device of this modification also forms a closed circuit 201.

  Thus, in the liquid fractionating device 200 of this modification, the separation device 220 that liquefies the mist MI by ultrasonically vibrating the cylindrical bolt member 147 is used. For this reason, similarly to the embodiment, energy consumption due to heating and cooling is suppressed, and the liquid to be treated can be efficiently distilled.

In the above, the present invention has been described with reference to the embodiments and the modified examples. However, the present invention is not limited to the above-described embodiments and modified examples, and can be appropriately modified and applied without departing from the gist thereof. Needless to say, it can be done.
For example, in the embodiment, the separation device 120 in which the pipe member 130 is fixed to the distal end side of the bolt tightened Langevin type vibrator 140 is shown. However, the separation device without the pipe member 130, that is, the bolt tightened Langevin type vibrator 140 is shown. Only 140 may be a separation device. Alternatively, on the contrary, a pipe member may be separately provided on the base end side of the vibrator 140.

  Further, in the modified example, the cylindrical bolt member 247 is exemplified as having a front end side protruding portion 247P that protrudes to the front end side of the front plate 244 (rightward in FIG. 4A). However, instead of this, as shown by a broken line in FIG. 4 (a), it has a base-side protruding portion 247Q that protrudes to the base end side of the backing plate 245 (leftward in FIG. 4 (a)), In the bolt through hole 247QI in the base end side protruding portion 247Q, the mist MI may be liquefied and collected by the standing portion standing wave sound field SS4 (see FIGS. 4B and 4C). Or you may make it have both the front end side protrusion part 247P and the base end side protrusion part 247Q.

  Further, in the present embodiment and the modification, the cylindrical bolt members 147 and 247 forming a part of the bolt tightened Langevin type vibrators 140 and 240 are used as a part or all of the ventilation through holes 140I and 240I through which the mist MI is passed. did. However, in addition to the cylindrical bolt member of the bolted Langevin type vibrator, a tube member that passes through the inside of the cylindrical bolt member is provided, and the bolted Langevin type vibrator generates ultrasonic vibration in the pipe member.
