Description

  The present invention relates to a liquid processing apparatus.

  In a water purification system such as a factory wastewater treatment facility, a mechanism capable of efficiently separating and removing suspended matter in a liquid sample is required. The suspended matter is a substance such as turbidity that is a solid component or a liquid component that is present in a dispersed state in a liquid, for example, and refers to an object to be separated.

  Conventionally, as a method for separating a suspended matter while feeding a liquid sample, there is a method for separating the suspended matter by irradiating the liquid sample with ultrasonic waves. For example, Patent Document 1 (International Publication No. 2016/042832) describes “an emulsion separator for separating an emulsion containing an oily component and an aqueous component, and an emulsion supplied with the emulsion. A supply section, an emulsion discharge section for discharging the separated emulsion, and a flow path section connected to the emulsion supply section; an emulsion supply section and an emulsion discharge section; Is connected via a first and a second piping unit, and the piping unit is composed of an ultrasonic vibration element and an ultrasonic reflection member arranged so as to face each other with the flow path portion interposed therebetween. ing.

  In the emulsion separator of Patent Document 1, a standing wave is formed in the flow channel by the irradiated ultrasonic wave, and the suspended matter aggregated by the standing wave has a high sedimentation speed, Settling down vertically (bottom of piping unit).

  However, turbidity settled at the bottom of the piping unit of Patent Document 1 is caused by the following two causes, for example, and most of them accumulate on the bottom of the piping unit. May become blocked. (1) The suspended turbidity stays as the movement in the downstream direction is hindered by the nodes connecting the piping units. (2) Since the vicinity of the bottom of the piping unit is the boundary layer region of the flow, the flow of the emulsion is slow, and the suspended turbidity tends to stay.

  An object of the present invention is to provide a technique for efficiently removing suspended matter separated from a liquid sample so as not to disturb the flow of the liquid.

[First Embodiment]
FIG. 1 is a diagram illustrating a configuration example of a liquid processing apparatus 10A according to the first embodiment. The liquid sample processed by this liquid processing apparatus 10A is, for example, a suspension containing turbidity. Arrow S in the figure indicates the position and direction in which the liquid sample is supplied, and arrows D1 and D2 indicate the position and direction in which the liquid sample is discharged. An arrow F in the figure indicates a flow path of the liquid sample. FIG. 2 is a diagram illustrating a configuration example of the supply-side piping unit 12.

  The liquid processing apparatus 10A is assembled by connecting a plurality of units. Specifically, the liquid processing apparatus 10 </ b> A includes a supply unit 11, a supply-side piping unit 12, a direction changing piping unit 14, and a discharge unit 15 in order from the upstream side of the flow path F of the liquid sample.

  The supply unit 11 includes a hollow portion (inside the broken line, may be referred to as a “flow path portion”) formed inside the housing, a supply port 111 provided on the upper surface in the Z-axis direction of the housing, And a discharge port 112 provided on the lower surface in the Z-axis direction. The supply port 111 is connected to, for example, another device or unit such as a pump that pushes out a liquid sample, a container that stores the liquid sample, and other piping units that send the liquid sample, and the liquid sample is supplied. The discharge port 112 is connected to the supply port 121 of the supply side piping unit 12.

  As shown in FIG. 2, the supply-side piping unit 12 includes a cavity formed inside the housing, a supply port 121 provided on the upper surface in the Z-axis direction of the housing, and a lower surface in the Z-axis direction of the housing. And an outlet 122 provided. The hollow portion has a rectangular parallelepiped shape whose XY cross section is rectangular. The discharge port 122 is connected to the supply port 141 of the direction changing piping unit 14.

  The supply-side piping unit 12 includes an ultrasonic irradiation unit 124 and a driving unit 125. The ultrasonic irradiation unit 124 has a planar vibration surface, and is installed so that the vibration surface contacts the YZ surface of the outer wall of the supply-side piping unit 12. The ultrasonic irradiation unit 124 is connected to the driving unit 125 and is driven by an electrical signal output from the driving unit 125. The driven ultrasonic irradiation unit 124 oscillates the vibration surface to irradiate ultrasonic waves in the positive direction of the X axis, and excites the liquid sample flowing in the cavity. As will be described later, the irradiated ultrasonic wave is reflected by the inner wall 123 of the supply-side piping unit 12 to form a standing wave. The ultrasonic irradiation unit 124 includes, for example, a piezoelectric ultrasonic vibration element.

  The driving unit 125 is connected to the control unit 13. The control unit 13 may be provided in the liquid processing apparatus 10A or may be provided in an external device. For example, the control unit 13 controls the driving unit 125 to control the on / off of the ultrasonic irradiation unit 124. Further, the control unit 13 may be able to control the flow of the liquid sample, for example, by controlling the on / off of the pump and the pressure. The control unit 13 can be realized by a microcomputer including a CPU (Central Processing Unit), a RAM (Random Access Memory), or a dedicated hardware circuit, for example.

  The direction changing piping unit 14 is provided in a hollow portion formed inside the housing, a supply port 141 and a discharge port 142 provided on the upper surface in the Z-axis direction of the housing, and a lower surface in the Z-axis direction of the housing. Floating matter discharge port 143 is provided. The supply port 141 and the discharge port 142 are arranged at positions separated from each other in the X-axis direction, and the liquid sample is supplied from the discharge port 142 in the liquid feeding direction (Z-axis minus direction) in which the liquid sample is supplied to the supply port 141. It arrange | positions so that the liquid feeding direction (Z-axis plus direction) discharged | emitted may be opposite. The discharge port 142 is connected to the supply port 151 of the discharge unit 15 and discharges the liquid sample (clarified liquid). The floating material discharge port 143 is disposed at a position facing the supply port 141, that is, disposed in front of the liquid feeding direction (Z-axis minus direction) in which the liquid sample is supplied to the supply port 141. The suspended matter discharge port 143 is connected to another device or unit such as a container for storing a liquid sample, a device for processing the liquid sample, another piping unit for feeding the liquid sample, and the liquid sample (concentrated liquid). Discharge.

  The discharge unit 15 includes a cavity formed inside the housing, a supply port 151 provided on the lower surface in the Z-axis direction of the housing, and a discharge port 152 provided on the upper surface in the Z-axis direction of the housing. . The discharge port 152 is connected to, for example, another device or unit such as a pump for sucking the liquid sample, a container for storing the liquid sample, another piping unit for feeding the liquid sample, and the liquid sample (clarified liquid). Discharge.

  By connecting the above units, the hollow portions of the units communicate with each other, and the flow path F can be formed. The liquid sample supplied from S reaches the direction change piping unit 14 via the supply unit 11 and the supply side piping unit 12. A part of the liquid sample flowing into the direction changing pipe unit 14 is discharged to D1 through the discharge unit 15. Another part of the liquid sample flowing into the direction changing piping unit 14 is discharged to D2.

  FIG. 3 is a diagram for explaining the irradiation direction of ultrasonic waves. When the ultrasonic irradiation unit 124 is driven by the electric signal E1 from the driving unit 125, the ultrasonic irradiation unit 124 converts the electric signal into ultrasonic vibration and irradiates the ultrasonic wave U in the plus direction of the X axis in the cavity. The liquid sample feeding direction is the Z-axis minus direction and is orthogonal to the traveling direction of the ultrasonic wave U. The ultrasonic wave U irradiated from the ultrasonic irradiation unit 124 propagates in the flowing liquid sample, and a part thereof is reflected by the facing inner wall 123, thereby forming a standing wave in which the incident wave and the reflected wave are synthesized. Is done. The standing wave formed by the ultrasonic wave U is a sound field corresponding to the frequency unique to the ultrasonic wave irradiation unit 124. That is, according to the specific frequency, the antinode 5 which is a low sound pressure region and the node 6 which is a high sound pressure region appear periodically along the X-axis direction.

  FIG. 4 is a diagram for explaining the behavior of turbidity. When a sound field is formed in the suspension flowing through the cavity of the supply side piping unit 12 by ultrasonic irradiation, the belly 5 and the node 6 are repeatedly generated along the X-axis direction. Here, when a turbidity sufficiently smaller than the interval between the abdomen 5 and the node 6 exists, the turbidity receives a force toward the abdomen 5 or 6 depending on the physical property value, and the position of the abdomen 5 or 6 (In FIG. 4, it is captured in section 6). The trapped turbid material aggregates due to intermolecular force or the like. The suspended matter that has agglomerated to a certain size settles in the negative direction of the Z-axis due to its own weight. In this way, at least some of the turbidity contained in the suspension is separated and concentrated.

  The suspended matter aggregated and settled in the supply side piping unit 12 reaches the direction changing piping unit 14 through the discharge port 122 and the supply port 141. The concentrated liquid containing the suspended turbidity is discharged from the suspended matter discharge port 143 to D2. The clarified liquid containing the remaining turbidity (preferably not containing turbidity) reaches the discharge unit 15 via the discharge port 142 and is discharged from the discharge port 152 to D1. In addition, it is preferable to control the speed of the flow in the X-axis plus direction in the direction changing piping unit 14 to such an extent that the suspended turbidity is not flowed in the X-axis plus direction as much as possible. For example, the control unit 13 may control the flow speed by controlling the pressure of the pump.

  The first embodiment of the present invention has been described above. In the first embodiment, the floating matter discharge port 143 of the direction changing piping unit 14 is disposed immediately below the front surface of the discharge port 122 of the supply side piping unit 12. Further, the discharge port 142 of the direction changing piping unit 14 is disposed at a spaced position on the same plane as the supply port 141. Thereby, the turbid substance aggregated by the ultrasonic wave is efficiently discharged from the suspended matter discharge port 143 in the settling direction, and the disturbance of the flow of the liquid sample can be reduced.

  In a modification of the first embodiment, the liquid processing apparatus 10 </ b> A may include one or more discharge-side piping units between the direction changing piping unit 14 and the discharging unit 15. The discharge side piping unit has the same configuration as the supply side piping unit 12, but does not include an ultrasonic irradiation unit and a driving unit.

The liquid processing apparatus 10B includes a plurality of supply-side piping units 12, and each supply-side piping unit 12 is connected in the Z-axis direction. The configuration of each supply-side piping unit 12 is the same as that in the first embodiment. The drive unit 125 of each supply-side piping unit 12 is connected to the control unit 13. The control unit 13 may be able to individually control each drive unit 125 on / off, or may be able to control all the on / off simultaneously.

  The liquid sample supplied from S reaches the direction change piping unit 14 via the supply unit 11 and the plurality of supply side piping units 12. A part of the liquid sample flowing into the direction changing pipe unit 14 is discharged to D1 through the discharge unit 15.

  The suspended matter aggregated and settled in the upstream supply side piping unit 12 reaches the downstream supply side piping unit 12. The suspended matter aggregated and settled in the downstream supply side piping unit 12 reaches the direction changing piping unit 14.

  In the second embodiment, the liquid sample is irradiated with ultrasonic waves in the plurality of supply-side piping units 12. Thereby, compared with 1st Embodiment, since the turbidity which was not aggregated on the upstream side can be aggregated on the downstream side, the separation performance of turbidity can be improved. In addition, by providing a plurality of ultrasonic irradiation units 124, liquid processing can be continued even when some ultrasonic irradiation units 124 are maintained.

  In a modified example of the second embodiment, some of the plurality of supply-side piping units 12 may not include the ultrasonic irradiation unit 124 and the driving unit 125.

Hereinafter, the same reference numerals are given to the same components as those in the second embodiment, and the description thereof will be omitted. The description will focus on the components different from those in the second embodiment.

  FIG. 6 is a diagram illustrating a configuration example of a liquid processing apparatus 10C according to the third embodiment. The liquid processing apparatus 10 </ b> C includes one or more discharge side piping units 16 (FIG. 6 shows a plurality of cases) between the direction changing piping unit 14 and the discharging unit 15. The configuration of the discharge side piping unit 16 is the same as the configuration of the supply side piping unit 12. Each discharge side piping unit 16 is connected in the Z-axis direction. The supply port of the most upstream discharge side piping unit 16 is connected to the discharge port 142. The discharge port of the most downstream discharge side piping unit 16 is connected to the supply port 151. The drive part of each discharge side piping unit 16 is connected to the control part 13. The control unit 13 may be capable of individually controlling on / off of each driving unit, or may be capable of performing on / off control of all of them simultaneously.

  The liquid processing apparatus 10 </ b> C includes a direction changing piping unit 14 </ b> C instead of the direction changing piping unit 14. The direction changing piping unit 14 </ b> C includes a floating matter discharge port 146 in addition to the configuration of the direction changing piping unit 14. The suspended matter discharge port 146 is disposed at a position facing the discharge port 142, that is, disposed on the opposite side of the liquid feeding direction (Z-axis plus direction) in which the liquid sample is discharged from the discharge port 142. The floating substance discharge port 146 is connected to another device or unit such as a container for storing a liquid sample, a device for processing the liquid sample, another piping unit for feeding the liquid sample, and the liquid sample (concentrated liquid). Discharge.

  The liquid sample supplied from S reaches the direction changing piping unit 14C via the supply unit 11 (not shown in FIG. 6) and the plurality of supply side piping units 12. A part of the liquid sample flowing into the direction changing piping unit 14C is discharged to D1 through one or more discharge side piping units 16 and the discharging unit 15. The other part of the liquid sample flowing into the direction changing piping unit 14C is discharged to D2 and D3.

  The suspended matter aggregated and settled in the plurality of supply side piping units 12 reaches the direction changing piping unit 14C via the discharge port 122 and the supply port 141. The concentrated liquid containing the suspended turbidity is discharged from the suspended matter outlet 143 and the suspended matter outlet 146 to D2 and D3, respectively. The suspended matter aggregated and settled in the one or more discharge side piping units 16 reaches the direction changing piping unit 14C via the discharge port 142. The concentrated liquid containing the suspended turbidity is discharged from the suspended matter discharge port 146 to D3. The clarified liquid containing the remaining turbidity (preferably not containing turbidity) reaches the discharge unit 15 and is discharged from the discharge port 152 to D1.

  In addition, it is preferable to make the length of the Z-axis direction of the several supply side piping unit 12 connected larger than the length of the Z-axis direction of the one or several discharge side piping unit 16 connected. If it does in this way, since it can pump using the principle of siphon, the head of the pump used for liquid feeding can be lowered. The same principle can be applied to other embodiments.

  In the third embodiment, the liquid sample is irradiated with ultrasonic waves in each of the one or more discharge side piping units 16. Thereby, compared with 2nd Embodiment, since the turbidity which was not aggregated by the supply side can be aggregated by the discharge | emission side, the separation performance of turbidity can be improved. In addition, by providing a plurality of ultrasonic irradiation units 124, liquid processing can be continued even when some ultrasonic irradiation units 124 are maintained.

  In a modified example of the third embodiment, some of the plurality of supply side piping units 12 may not include the ultrasonic irradiation unit 124 and the driving unit 125. Some of the plurality of discharge side piping units 16 may not include the ultrasonic irradiation unit 124 and the driving unit 125.

[Reference Example]
Reference examples will be described for evaluating whether aggregated and settled turbidity is efficiently discharged.

  FIG. 7 is a diagram showing a configuration of a reference example regarding the discharge performance of separated turbidity. In this example, a liquid processing apparatus 10e simulating the liquid processing apparatus 10C of the third embodiment was produced. The liquid processing apparatus 10e includes a supply unit 11e (100 mm × 40 mm × 80 mm), two supply side piping units 12e (40 mm × 40 mm × 40 mm), a direction changing piping unit 14e (140 mm × 40 mm × 60 mm), and a discharge side A piping unit 16e (40 mm × 40 mm × 40 mm) and a discharge unit 15e (30 mm × 30 mm × 40 mm) are provided.

  The two supply-side piping units 12e and the discharge-side piping unit 16e are each attached with an ultrasonic vibration element 124e (20 mm × 20 mm) as an ultrasonic irradiation unit on the YZ surface. Each ultrasonic vibration element 124e is connected to a common drive unit 125e and driven at a resonance frequency of 2.20 MHz.

  The direction change piping unit 14e is provided with two floating matter discharge ports 143e1 and 143e2 (each having an inner diameter of 2 mm) on the lower surface in the Z-axis direction. The floating material discharge port 143e1 is disposed at a position facing the supply port 141e. The floating material discharge port 143e2 is disposed at a position facing an intermediate point between the supply port 141e and the discharge port 142e. The discharge unit 15e is provided with a discharge port 152e (inner diameter: 2 mm) on the right surface in the X-axis direction.

  A pump (not shown) was connected to each of the floating material discharge port 143e1, the floating material discharge port 143e2, and the discharge port 152e through a Tygon tube so that liquid could be fed at the same flow rate.

  In this example, a suspension in which alumina particles (average particle size: 2.8 μm) were dispersed in tap water at a concentration of 2 g / L was used as a sample liquid (turbidity before treatment: 182 degrees). Since the concentration of alumina particles is proportional to the turbidity of the sample liquid, the turbidity of the sample liquid before and after the treatment is measured and the discharge performance of the alumina particles is evaluated in order to verify the effect on the turbidity discharge performance of the liquid processing apparatus 10e. did.

Specifically, in order to evaluate the discharge performance, two measurements were performed. In the first measurement, the floating solution discharge port 143e1 and the discharge port 152e are opened, and the floating solution discharge port 143e2 is sealed, and the sample liquid is supplied to the supply unit 11e (S in the figure). The turbidity of the sample liquid discharged from the outlet 143e1 (A in the figure) and the turbidity of the sample liquid discharged from the outlet 152e (C in the figure) were measured. In the second measurement, the floating liquid discharge port 143e2 and the discharge port 152e are opened, and the floating liquid discharge port 143e1 is sealed, and the sample liquid is supplied to the supply unit 11e and discharged from the floating material discharge port 143e2. The turbidity of the sample liquid (B in the figure) and the turbidity of the sample liquid discharged from the discharge port 152e were measured. In any measurement, the ultrasonic vibration element was driven with an electric signal having an output of 9.3 W / cm ² while feeding the sample liquid at a flow rate of 1.25 mm / sec.

  FIG. 8 is a diagram showing the results of a reference example regarding the discharge performance of separated turbidity. In the graph of FIG. 8, the vertical axis represents the turbidity after the treatment, and the horizontal axis represents the measurement position (A, B, C). The left side (a) of the graph of FIG. 8 shows the result of the first measurement, and the right side (b) shows the result of the second measurement.

  In the first measurement, the turbidity at the measurement position A increased to 301 degrees, and the turbidity at the measurement position C decreased to 51 degrees. That is, a concentrated liquid having a higher concentration of alumina particles than the sample liquid before processing is discharged from the suspended matter discharge port 143e1, and a clarified liquid having a concentration of alumina particles lower than that of the sample liquid before processing is discharged from the discharge port 152e. I understand that.

  In the second measurement, the turbidity at the measurement position C is approximately the same as that in the first measurement, but the turbidity at the measurement position B increased only to 139 degrees. That is, a clarified liquid having a concentration of alumina particles lower than that of the sample liquid before processing is discharged from the suspended matter discharge port 143e2, and a clarified liquid having a concentration of alumina particles lower than that of the sample liquid before processing is discharged from the discharge port 152e. I understand that.

  From these comparison results, it can be said that the suspended matter discharge port 143e can be more efficiently discharged by arranging the float discharge port 143e at a position facing the supply port 141e. In the second measurement, it is considered that more agglomerated and settled alumina particles were accumulated on the left bottom surface of the suspended matter discharge port 143e2 in the direction changing piping unit 14e as compared with the case of the first measurement.

[Fourth Embodiment]
The liquid processing apparatus according to the fourth embodiment includes a direction changing piping unit including an ultrasonic irradiation unit. Hereinafter, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof will be omitted. The description will focus on the components different from those in the first embodiment.

  FIG. 9 is a diagram illustrating a configuration example of a liquid processing apparatus 10D according to the fourth embodiment. FIG. 10 is a diagram illustrating a configuration example of the direction changing piping unit 14D. The liquid processing apparatus 10 </ b> D includes a direction changing piping unit 14 </ b> D instead of the direction changing piping unit 14. The direction conversion piping unit 14D includes an ultrasonic irradiation unit 144 and a driving unit 145 in addition to the same configuration as the direction conversion piping unit 14.

  The hollow portion of the direction changing piping unit 14D has a rectangular parallelepiped shape whose XY cross section is rectangular. The ultrasonic irradiation unit 144 is provided on the YZ surface of the outer wall of the direction conversion piping unit 14D. The drive unit 145 is connected to the ultrasonic irradiation unit 144.

  When driven by the electric signal E2 from the drive unit 145, the ultrasonic irradiation unit 144 converts the electric signal into ultrasonic vibration and irradiates the ultrasonic wave U in the plus direction of the X axis in the cavity. The liquid sample feeding direction is the plus direction of the X axis and coincides with the traveling direction of the ultrasonic wave U. The ultrasonic wave U irradiated from the ultrasonic wave irradiation unit 144 propagates in the flowing liquid sample, and a part thereof is reflected by the opposing inner wall (right surface in the X-axis direction), thereby combining the incident wave and the reflected wave. A standing wave is formed. As a result, antinodes 5 and nodes 6 are repeatedly generated along the X-axis direction. The suspended matter captured at the position of the abdomen 5 or the node 6 aggregates due to intermolecular force or the like. The suspended matter that has agglomerated to a certain size settles in the negative direction of the Z-axis by its own weight.

  In the fourth embodiment, the liquid sample is irradiated with ultrasonic waves not only in the supply side piping unit 12 but also in the direction changing piping unit 14D. Thereby, the turbidity that has not been aggregated in the supply-side piping unit 12 can also be aggregated in the direction changing piping unit 14D, so that the turbidity separation performance can be improved. In addition, by providing a plurality of ultrasonic irradiation units 124 and 144, the liquid treatment can be continued even when some ultrasonic irradiation units are maintained.

  Furthermore, in the fourth embodiment, the liquid sample feeding direction in the direction changing piping unit 14D is the same as the traveling direction of the ultrasonic waves, that is, intersects the belly 5 and the node 6 formed substantially parallel to the YZ plane. To do. As a result, the turbidity contained in the liquid sample flowing in the positive direction of the X axis crosses the abdomen 5 and the node 6, and is thus easily captured by the abdomen 5 or the node 6. Compared with this, since the liquid-sending direction of the liquid sample in the supply side piping unit 12 is parallel to the belly 5 and the node 6 formed parallel to the YZ plane, the turbidity is between the belly 5 and the node 6. May pass.

  In a modified example of the fourth embodiment, the supply side piping unit 12 may not include the ultrasonic irradiation unit 124 and the driving unit 125. In another modification, the direction changing piping unit 14D may be applied to other embodiments.

[Fifth Embodiment]
The liquid processing apparatus according to the fifth embodiment includes an ultrasonic reflection plate in the direction conversion piping unit. Hereinafter, the same reference numerals are given to the same components as those in the fourth embodiment, and the description thereof will be omitted. The description will focus on the components different from those in the fourth embodiment.

  FIG. 11 is a diagram illustrating a configuration example of a liquid processing apparatus 10E according to the fifth embodiment. The direction conversion piping unit 14D includes an ultrasonic reflection plate 147 in the cavity. In the example of FIG. 11, the ultrasonic reflection plate 147 is closer to the ultrasonic irradiation unit 144 than the discharge port 142 and is disposed at a substantially central portion in the X-axis direction in the cavity. The dimension of the ultrasonic reflector 147 in the Y-axis direction matches the dimension of the cavity in the Y-axis direction, and the dimension of the ultrasonic reflector 147 in the Z-axis direction is set shorter than the dimension of the cavity in the Z-axis direction. Is done. That is, the area of the YZ plane of the ultrasonic reflector 147 is set smaller than the YZ cross-sectional area of the cavity. Both side surfaces (XZ surface) and bottom surface (XY surface) of the ultrasonic reflector 147 are fixed so as to be in close contact with both side surfaces (XZ surface) and bottom surface (XY surface) of the cavity. Accordingly, a gap through which the liquid sample passes is formed above the ultrasonic reflecting plate 147 in the Z-axis direction.

  The ultrasonic wave U irradiated from the ultrasonic wave irradiation unit 144 propagates in the flowing liquid sample, and a part of the ultrasonic wave U is reflected by the opposing ultrasonic wave reflection plate 147, so that the incident wave and the reflected wave are combined. A wave is formed.

  In the fifth embodiment, the distance to the ultrasonic reflection surface is set shorter than in the fourth embodiment. Thereby, since attenuation of an ultrasonic wave is reduced compared with 4th Embodiment, the sound pressure of a standing wave can be improved. As a result, the performance of trapping and agglomerating turbidity can be improved as compared with the fourth embodiment. Further, by closing the cross section of the cavity except for the upper part of the ultrasonic reflector 147, the amount of turbidity moving to the downstream side of the ultrasonic reflector 147 can be reduced, and the efficiency of capture and aggregation can be improved. it can.

  In a modified example of the fifth embodiment, the ultrasonic reflecting plate 147 is fixed so that the size of the ultrasonic reflecting plate 147 in the YZ-axis direction matches the size of the hollow portion in the YZ-axis direction, and the hollow portion is sealed. Also good. In this case, the ultrasonic reflector 147 is provided with a plurality of through holes penetrating in the X-axis direction in order to flow the liquid sample. The inner diameter of each through hole is set to be shorter than the wavelength of the ultrasonic wave irradiated from the ultrasonic irradiation unit 144. In this way, since the movement of turbidity is obstructed by the ultrasonic reflector 147, the efficiency of capture and aggregation can be improved. Further, since the ultrasonic wave is prevented from being transmitted to the opposite side of the ultrasonic wave reflection plate 147, the sound pressure of the standing wave can be improved.

  In another modification of the fifth embodiment, the supply side piping unit 12 may not include the ultrasonic irradiation unit 124 and the driving unit 125. In still another modification, the direction changing piping unit 14D may be applied to other embodiments.

[Sixth Embodiment]
The liquid processing apparatus of the sixth embodiment is obtained by vertically inverting the liquid processing apparatus 10A of the first embodiment. Hereinafter, a description will be given focusing on differences from the first embodiment.

The liquid sample processed by this liquid processing apparatus 10F is, for example, an emulsion containing oil droplets. The liquid processing apparatus 10F is obtained by inverting the liquid processing apparatus 10A of the first embodiment upside down.

  The liquid sample supplied from S reaches the direction change piping unit 14 via the supply unit 11 and the supply side piping unit 12. A part of the liquid sample flowing into the direction changing pipe unit 14 is discharged to D1 through the discharge unit 15. Another part of the liquid sample flowing into the direction changing piping unit 14 is discharged to D2.

  When a sound field is formed in the emulsion flowing through the cavity of the supply side piping unit 12 by ultrasonic irradiation, the abdomen 5 and the node 6 are repeatedly generated along the X-axis direction. Here, when an oil droplet sufficiently smaller than the interval between the belly 5 and the node 6 exists, the oil droplet receives a force toward the belly 5 or the node 6 according to the physical property value, and the position of the belly 5 or the node 6 is detected. (In the example of FIG. 12, it is captured by the belly 5 shown in FIG. 3). The captured oil droplets aggregate due to intermolecular force or the like. The oil droplets that have agglomerated to a certain size float up in the positive direction of the Z-axis by their own buoyancy. In this way, at least some of the oil droplets contained in the emulsion are separated and concentrated.

The concentrated liquid containing the floating oil droplets is discharged from the floating material discharge port 143 to D2. The clarified liquid containing the remaining oil droplets (preferably not containing oil droplets) reaches the discharge unit 15 via the discharge port 142 and is discharged from the discharge port 152 to D1. In addition, it is preferable that the speed of the flow in the X-axis plus direction in the direction change piping unit 14 is controlled to such an extent that floating oil droplets are not flowed in the X-axis plus direction as much as possible. For example, the control unit 13 may control the flow speed by controlling the pressure of the pump.

  The sixth embodiment of the present invention has been described above. In the sixth embodiment, the floating matter discharge port 143 of the direction changing piping unit 14 is arranged immediately above the front surface of the discharge port 122 of the supply side piping unit 12. Further, the discharge port 142 of the direction changing piping unit 14 is disposed at a spaced position on the same plane as the supply port 141. As a result, the oil droplets aggregated by the ultrasonic waves are efficiently discharged from the suspended matter discharge port 143 in the rising direction, and obstruction of the flow of the liquid sample can be reduced.

Thereby, compared with 6th Embodiment, since the oil droplet which was not aggregated in the upstream can be aggregated in the downstream, the separation performance of an oil droplet can be improved. In the seventh embodiment, the liquid sample is irradiated with ultrasonic waves in the one or more discharge-side piping units 16. Thereby, compared with 6th Embodiment, since the oil droplet which was not aggregated by the supply side can be aggregated by the discharge side, the separation performance of an oil droplet can be improved.
