  The manufacturing apparatus 10 according to the embodiment of the present invention suppresses fluctuations in the concentration of each chemical solution in a manufacturing process for manufacturing a two-component on-site type slime control agent (bactericide), and a two-component slime control agent. In the following, the manufacturing apparatus 10 of the preferred embodiment for realizing the manufacturing method of the present invention will be described with reference to FIGS. Hereinafter, although embodiment of this invention is described, this invention is not specifically limited to this.

[First Embodiment]
FIG. 1 is a block diagram of a manufacturing apparatus 10 according to the first embodiment of the present invention. As shown in FIG. 1, the manufacturing apparatus 10 includes a first flow path 20 for circulating an amine donor as a chemical solution, a second flow path 30 for flowing an oxidant donor as a chemical liquid, a first flow path 20 and a first flow path. A pump control device 41 that controls the pump of the two flow paths 30 and a merging section 42 that joins the amine donor that flows in the first flow path 20 and the oxidant donor that flows in the second flow path 30 are provided. Details of each element will be described below.

[Block Diagram]
The first flow path 20 extends from the first tank 21, the first pump 23, the first amplitude suppression means 24, and the first pump 23 to the first amplitude suppression means 24, and the first tank 21, the first pump 23, and the first The first introduction pipe 22 that connects the amplitude suppression means 24 and the first outlet pipe 25 that extends from the first amplitude suppression means 24 to the junction 42 and connects the first amplitude suppression means 24 and the junction 42 are provided. Similarly, the second flow path 30 extends from the second tank 31, the second pump 33, the second amplitude suppression means 34, and the second pump 33 to the second amplitude suppression means 34, and the second tank 31 and the second pump 33 and the second amplitude suppression means 34, and a second lead-out pipe 35 extending from the second amplitude suppression means 34 to the junction 42 and connecting the second amplitude suppression means 34 and the junction 42. Is provided. The first tank 21 constituting the first flow path 20, the first introduction pipe 22, the first pump 23, the first amplitude suppressing means 24, the first outlet pipe 25, and the second tank 31 constituting the second flow path 30. Since the second introduction pipe 32, the second pump 33, the second amplitude suppression means 34, and the second outlet pipe 35 have substantially the same configuration, only the configuration different from the first flow path 20 will be described.

  The 1st tank 21 and the 2nd tank 31 are constituted so that an amine donor and an oxidizer donor can be stored as a chemical solution which manufactures a slime control agent, respectively. Examples of amine donors include water-soluble ammonium salts, ammonium bromide, ammonium sulfate aqueous solution, and ammonium chloride aqueous solution. Examples of oxidant donors include hypohalous acid generating compounds and peroxides. The concentration of the amine donor stored in the first tank 21 and the oxidant donor stored in the second tank 31 is 0.1 to 99% (w / v).

  In the present invention, the “two-component system” refers to one composed of two or more chemical solutions. That is, the number of tanks that store the chemical solution is not limited to two, that is, the first tank 21 and the second tank 31, and three or more tanks similar to the first tank 21 and the second tank 31 are provided, and each of the plurality of tanks is different. You may store the chemical | medical solution which consists of a component. Thereby, each chemical | medical solution stored in the some tank can be mixed and manufacture of a multi-liquid type slime control agent can be performed.

  The amine donor stored in the first tank 21 is led out to the junction 42 by the first pump 23, and the oxidant donor stored in the second tank 31 is led out to the junction 42 by the second pump 33. The

  The first pump 23 and the second pump 33 are not limited as long as the liquid flow is quantitatively performed. Generally, the first pump 23 and the second pump 33 are a diaphragm pump, a plunger pump, or a bellows pump. Generate amplitude. For example, in a diaphragm pump, a part of a pump chamber that discharges and sucks chemical liquid is composed of an elastic body such as a diaphragm (membrane), and the diaphragm is expanded and contracted by reciprocating the diaphragm to discharge and suck chemical liquid. It is carried out. For this reason, the chemical liquid is supplied when the first pump 23 is discharged, and when the first pump 23 is inhaled, the chemical liquid is inhaled by the action of a check valve (not shown) provided in the first pump 23. Instead, the chemical supply is stopped. Therefore, a pulsation is generated from the diaphragm with the discharge and suction of the first pump 23, and an amplitude of the flow rate of the chemical solution is generated with the pulsation. The same applies to the plunger pump and the bellows pump. Then, the occurrence of such an amplitude of the chemical solution circulation amount is a cause of the fluctuation of the mixing ratio of each chemical solution. Therefore, the first amplitude suppression unit 24 and the second amplitude suppression unit 34 for suppressing the concentration fluctuation of the mixing ratio of the chemical solution will be described in detail with reference to FIG.

  The first amplitude suppression unit 24 is disposed between the first pump 23 and the merging portion 42 and suppresses the amplitude of the flow rate of the chemical liquid that accompanies the pulsation that occurs when the chemical liquid is supplied from the first pump 23. The first amplitude suppression unit 24 is connected to the first tank 21 and the first pump 23 via the first introduction pipe 22 and is connected to the junction 42 via the first outlet pipe 25. Similarly, the second amplitude suppression means 34 is disposed between the second pump 33 and the merging portion 42, and suppresses the amplitude of the flow rate of the chemical liquid that accompanies the pulsation that occurs when the chemical liquid is supplied from the second pump 33. To do. The second amplitude suppression unit 34 is connected to the second tank 31 and the second pump 33 through the second introduction pipe 32 and is connected to the junction 42 through the second outlet pipe 35. Thereby, the amplitude of the flow rate of the chemical liquid supplied from the first pump 23 or the second pump 33 can be suppressed before reaching the junction portion 42.

  In the present embodiment, the first amplitude suppression unit 24 and the second amplitude suppression unit 34 are disposed upstream of the junction 42. Thereby, in the 1st amplitude suppression means 24 or the 2nd amplitude suppression means 34, the amplitude of the flow volume of the chemical | medical solution supplied from the 1st pump 23 or the 2nd pump 33 can be suppressed before reaching the confluence | merging part 42. .

  Further, in the present embodiment, the first amplitude suppression unit 24 is disposed between the first pump 23 and the junction unit 42, and the second amplitude suppression unit 34 is disposed between the second pump 33 and the junction unit 42. doing. Thereby, since the mixing ratio of each chemical | medical solution derived | led-out from both the 1st pump 23 and the 2nd pump 33 can be made constant, the quality of the two-liquid type slime control agent can be stabilized. However, the present invention is not limited to this, and for example, only one of the first amplitude suppression unit 24 and the second amplitude suppression unit 34 may be arranged. Among them, it is possible to suppress the amplitude of the flow rate of the chemical liquid derived in any flow path provided with the amplitude suppressing means.

  In the junction 42, the amine donor derived by the first pump 23 and the oxidant donor derived by the second pump 33 merge and mix with each other. In the present embodiment, the chemical solution mixed in the merging portion 42 is diluted with a solvent supplied through a solvent tube (not shown). Thereby, the chemical | medical solution mixed in the state by which the fluctuation range of the mixing ratio of an amine donor and an oxidizing agent donor was reduced can be diluted with a solvent, and the quality of a slime control agent can be stabilized.

[Amplitude suppression means]
The first amplitude suppression unit 24 and the second amplitude suppression unit 34 will be described with reference to FIG. Since the second amplitude suppression unit 34 has substantially the same configuration as the first amplitude suppression unit 24, description of the second amplitude suppression unit 34 is omitted, and only the first amplitude suppression unit 24 will be described.

  The first amplitude suppression unit 24 includes a storage tank 61 having a substantially sealed space 65 in which liquid and gas are stored. The first amplitude suppression means 24 is also called an air chamber, a receiver tank, or an air damper. When the chemical liquid is discharged from the first pump 23, the air in the air layer 63 is compressed, so that the instantaneous discharge pressure in the sealed space 65 is reduced. When the first pump 23 absorbs and the discharge of the chemical solution from the first pump 23 is stopped, the compressed air layer 63 expands and the chemical solution is derived.

  The storage tank 61 is configured such that the volume of the sealed space 65 is substantially constant. The sealed space 65 includes a liquid layer 62 that is an introduced chemical solution and a gas layer 63 that is a portion other than the liquid layer 62. Occupied. The gas layer 63 functions as a buffer layer for absorbing the increased pressure in the sealed space 65 of the storage tank 61. The storage tank 61 is made of a plastic or metal material having airtightness and pressure resistance, and holds the liquid and gas to which pressure is applied. The gas layer 63 is made of a substance such as air that does not react with the amine donor of the liquid layer 62 and maintains a gaseous state in an environment where the first amplitude suppression unit 24 is used.

  A blow valve 64 is provided at the upper end of the storage tank 61, and this blow valve 64 discharges the gas in the sealed space 65 to the outside when the pressure applied in the storage tank 61 becomes excessive. The blow valve 64 is closed when the pressure applied in the sealed space 65 is within a predetermined allowable range, and the air layer 63 in the sealed space 65 is blocked from the outside.

  The opening 25 a of the first outlet pipe 25 is disposed on the lower side by a predetermined distance from the upper end of the sealed space 65 so as to be located in the liquid layer 62. Thereby, the opening 25a is always located in the liquid layer 62, and the liquid can be led out. The opening 22 a of the first introduction pipe 22 is disposed above the lower end of the sealed space 65 by a predetermined distance so as to be located in the gas layer 63. The liquid introduced from the first introduction pipe 22 is led out from the first lead-out pipe 25 as the gas volume in the sealed space 65 increases or decreases. On the other hand, the position of the opening 22a of the first introduction pipe 22 does not matter whether it is in the liquid layer 62 or the gas layer 63, but is preferably in the gas layer 63.

  With reference to FIG. 2, the operation of the first amplitude suppression means 24 will be described. Since the second amplitude suppression unit 34 has substantially the same configuration as the first amplitude suppression unit 24, only the operation of the first amplitude suppression unit 24 will be described.

  As shown in FIG. 2 (1), before the chemical liquid is discharged from the first pump 23, the pressures of the liquid layer 62 and the gas layer 63 are balanced.

  Next, when the chemical liquid is discharged from the first pump 23, the discharged chemical liquid is discharged from the opening 22a of the first introduction pipe 22 through the first introduction pipe 22, as shown in FIG. The As a result, the amount of liquid in the liquid layer 62 increases, and the upper edge 62a of the liquid layer 62 is pushed upward. Then, the air in the gas layer 63 is compressed as the liquid layer 62 increases, and absorbs the increased volume of the liquid layer 62. At this time, the pressure in the gas layer 63 increases.

  Next, when the first pump 23 performs inhalation, the supply amount of the chemical solution from the first pump 23 decreases, so as shown in FIG. The layer 63 starts to expand, and gradually pushes down the upper edge 62a of the liquid layer 62 downward. As a result, the chemical liquid in the liquid layer 62 enters the opening 25a of the first outlet pipe 25 and is discharged to the merging portion 42 side, and eventually the state of FIG. 2 (1) where the pressure of the liquid layer 62 and the gas layer 63 is balanced. Return to.

  The compression and expansion of the gas layer 63 is a passive action that accompanies increase / decrease in the liquid layer 62, and therefore its speed is slower than the increase / decrease speed of the liquid layer 62. For this reason, compared with the amplitude of the discharge amount of the chemical liquid, the amplitude of the discharge amount of the chemical liquid is suppressed. The presence or absence of such amplitude suppression is specified by monitoring the discharge amount of the chemical solution introduced from the first introduction tube 22 and the discharge amount of the chemical solution derived from the first lead-out tube 25 over time. be able to. That is, when the discharge amount of the chemical solution introduced from the first introduction tube 22 and the discharge amount of the chemical solution discharged from the first lead-out tube 25 are monitored over time, the former amplitude width is smaller than the latter amplitude width. It can be specified that the amplitude is suppressed.

  As described above, even if the amplitude of the flow rate of the chemical liquid is generated with the discharge and suction of the first pump 23 and the second pump 33, the increase and decrease of the gas volume in the sealed space 65 in the storage tank 61 are repeated, thereby The chemical liquid can be supplied with an amplitude smaller than the amplitude of the flow rate when the chemical liquid is supplied from the first pump 23 and the second pump 33. Thus, even when using a pump made with a simple configuration such as a diaphragm pump, plunger pump or bellows pump in which the amplitude of the flow rate of the chemical solution is generated by pulsation, an amino donor when producing a slime control agent And the fluctuation range of the mixing ratio of the oxidant donor can be reduced.

  Here, as shown in FIG. 5, a third flow path 50 may be provided through which a solvent for diluting the chemical solution merged in the merge section 42 is circulated. By providing the third flow path 50, the amine donor stored in the first tank 21 and the oxidant donor stored in the second tank 31 are respectively led out to the third flow path 50 via the junction 42. The

  The third flow path 50 merges with the first flow path 20 and the second flow path 30 via a merge portion 42 disposed downstream of the first pump 23 and the second pump 33, and dilutes the amine donor and the oxidant donor. The solvent tank 51, the solvent pump 52, and the solvent pipe | tube 53 are comprised so that the solvent to distribute | circulate may be distribute | circulated.

  The solvent tank 51 stores a solvent (for example, water) for diluting the chemical solution that is merged and mixed in the merging unit 42, and the solvent pump 52 sucks up the solvent stored in the solvent tank 51 by a certain amount. To the solvent tube 53. The solvent pipe 53 mixes the solvent supplied from the solvent pump 52 with the chemical supplied from the merging section 42, and then supplies the solvent to a place where slime control is to be performed, such as a pulp production line or a circulating cooling water line. Here, an amplitude suppression unit similar to the first amplitude suppression unit 24 or the second amplitude suppression unit 34 may be disposed between the solvent pump 52 and the merging portion 42. Thereby, since a solvent is averaged and supplied, the density | concentration of the chemical | medical solution in a slime control agent can be homogenized.

  The first amplitude suppressing unit 24 and the second amplitude suppressing unit 34 of the manufacturing apparatus 10 ′ including the third channel 50 are disposed upstream of the third channel 50. Thereby, in the first amplitude suppression means 24 or the second amplitude suppression means 34, the amplitude of the flow rate of the chemical liquid supplied from the first pump 23 or the second pump 33 is suppressed before reaching the third flow path 50. Can do.

  When the merge part 42 is located upstream of the third flow path 50, the mixed chemical solution flows to the solvent tube 53 of the third flow path 50 and is diluted with the solvent. Thereby, the chemical | medical solution mixed in the state by which the fluctuation range of the mixing ratio of an amine donor and an oxidizing agent donor was reduced can be diluted with a solvent, and the quality of a slime control agent can be stabilized. However, the present invention is not limited to this. For example, the merging portion 42 may be installed in the solvent pipe 53 of the third flow channel 50 and may be merged after the amine donor and / or the oxidant donor is diluted.

[Second Embodiment]
Next, a manufacturing apparatus according to another embodiment of the present invention will be described with reference to FIG. The manufacturing apparatus according to the second embodiment is different from the manufacturing apparatus according to the first embodiment in that pulsation is prevented by an bellows type amplitude suppressing means instead of an air chamber type amplitude suppressing means.

[Amplitude suppression means]
With reference to FIG. 3, the first amplitude suppression unit 24A and the second amplitude suppression unit 34A of the second embodiment will be described. Since the second amplitude suppressing unit 34A has substantially the same configuration as the first amplitude suppressing unit 24A, only the first amplitude suppressing unit 24A will be described.

  The first amplitude suppression unit 24A includes a storage tank 61A having a substantially sealed space 65A in which liquid and gas are stored. The storage tank 61A is made of an elastic material having a certain elastic force so that the volume of the sealed space 65A is variable, and the increase / decrease of the gas volume is caused by the increase / decrease of the volume in the sealed space 65A. The first amplitude suppression unit 24A of the second embodiment absorbs the instantaneous discharge pressure of the sealed space 65A by expanding the storage tank 61A when discharging the first pump 23, and when sucking the first pump 23. That is, when the discharge of the chemical solution from the first pump 23 is stopped, the chemical solution is led out by gradually contracting the expanded storage tank 61A.

  The storage tank 61 </ b> A is configured such that the volume of the sealed space 65 </ b> A is variable, and the sealed space 65 </ b> A is occupied by a liquid layer 62 that is an introduced chemical solution and a gas layer 63 that is a part other than the liquid layer 62. It is done. The storage tank 61A formed of the stretchable material functions as a buffer material for absorbing the increased pressure in the sealed space 65 of the storage tank 61A. The storage tank 61 </ b> A is formed of a flexible plastic material or the like that expands and contracts according to the liquid and gas to which pressure is applied and has a restoring force to restore the original shape. By forming the storage tank 61A in a bellows shape that can be expanded and contracted in a substantially vertical direction, the shape change during expansion becomes constant, and the manufacturing apparatus 10 can be made compact. The gas layer 63 is made of a substance such as air that does not react with the amine donor of the liquid layer 62 and maintains a gaseous state in an environment where the first amplitude suppression unit 24 is used. However, the shape of the storage tank 61A is not limited to a substantially cylindrical bellows, but the storage tank 61A is formed of an elastomer such as rubber that can be expanded and contracted, and the storage tank 61A is expanded and contracted in an arbitrary direction. You may absorb the pressure which increased in the sealed space 65 of 61 A of storage tanks.

  The opening 25a of the first outlet pipe 25 is located in the liquid layer 62 and is disposed at a predetermined distance downward from the upper end of the sealed space 65 so as to be in contact with the upper end edge 62a of the liquid layer 62, and the upper end of the storage tank 61A. It is fixed in. Thereby, the opening 25a is always located in the liquid layer 62, and the liquid can be led out. The opening 22 a of the first introduction pipe 22 is arranged above the lower end of the sealed space 65 by a predetermined distance so as to be located in the liquid layer 62. The liquid introduced from the first introduction pipe 22 is led out from the first lead-out pipe 25 as the volume in the sealed space 65 increases or decreases. On the other hand, the position of the opening 22a of the first introduction tube 22 does not matter whether it is in the liquid layer 62 or the gas layer 63, but is preferably in the liquid layer 62. The opening 25 a of the first outlet pipe 25 is disposed so as to be in contact with the upper end edge 62 a of the liquid layer 62, but is not limited thereto, and may be in the liquid layer 62. Further, the first outlet pipe 25 does not necessarily need to be fixed at the upper end of the sealed space 65, but may be connected in a sealed state and the opening 25 a of the first outlet pipe 25 may be in the liquid layer 62.

  With reference to FIG. 3, the operation of the first amplitude suppression means 24A will be described. Since the second amplitude suppression unit 34A has substantially the same configuration as the first amplitude suppression unit 24A, only the operation of the first amplitude suppression unit 24A will be described.

  As shown in FIG. 3 (1), before the chemical liquid is discharged from the first pump 23, the pressure applied to the liquid layer 62 and the gas layer 63 and the restoring force for returning to the original shape of the storage tank 61A are as follows. It is balanced.

  Next, when the chemical liquid is discharged from the first pump 23, the discharged chemical liquid is discharged from the opening 22a of the first introduction pipe 22 through the first introduction pipe 22, as shown in FIG. The As a result, the amount of liquid in the liquid layer 62 increases, and the upper edge 62a of the liquid layer 62 is pushed upward. Then, the storage tank 61 </ b> A is expanded and absorbs the increase in the capacity of the liquid layer 62. At this time, the storage tank 61A has a restoring force to return to the original shape.

  Next, when the first pump 23 performs inhalation, the supply amount of the chemical solution from the first pump 23 decreases, so that the expanded storage tank 61A is restored to its original shape by the restoring force as shown in FIG. Therefore, the storage tank 61A starts to deform, and gradually pushes down the upper edge 62a of the liquid layer 62 downward. Thereby, the chemical liquid in the liquid layer 62 enters the opening 25a of the first outlet pipe 25 and is discharged to the joining portion 42 side, and eventually the pressure applied to the liquid layer 62 and the gas layer 63 and the original shape of the storage tank 61A are restored. Returning to the state of FIG. 3A in which the restoring force to be returned is balanced.

  The restoring force for returning to the original shape of the storage tank 61 </ b> A is a passive action accompanying the increase / decrease of the liquid layer 62, and therefore the speed thereof is slower than the increase / decrease speed of the liquid layer 62. For this reason, compared with the amplitude of the discharge amount of the chemical liquid, the amplitude of the discharge amount of the chemical liquid is suppressed.

  As described above, even when the amplitude of the flow of the chemical liquid is generated with the discharge and suction of the first pump 23 and the second pump 33, the first pump 23 and the second pump 33 are repeatedly expanded and contracted by the storage tank 61A. The chemical solution having an amplitude smaller than the amplitude of the flow rate when the chemical solution is supplied from can be supplied. Thus, even when using a pump made with a simple configuration such as a diaphragm pump, plunger pump or bellows pump in which the amplitude of the flow rate of the chemical solution is generated by pulsation, an amino donor when producing a slime control agent And the fluctuation range of the mixing ratio of the oxidant donor can be reduced.

[Third Embodiment]
Next, a manufacturing apparatus according to another embodiment of the present invention will be described with reference to FIG. The manufacturing apparatus according to the third embodiment is different from the manufacturing apparatus according to the first embodiment in that pulsation is prevented by an amplitude suppression means provided with a stretchable body rather than an air chamber type amplitude suppression means.

[Amplitude suppression means]
With reference to FIG. 4, the 1st amplitude suppression means 24B and the 2nd amplitude suppression means 34B of 3rd Embodiment are demonstrated. Since the second amplitude suppression unit 34B has substantially the same configuration as the first amplitude suppression unit 24B, only the first amplitude suppression unit 24B will be described.

  The first amplitude suppressing unit 24B of the third embodiment includes a storage tank 61B having a substantially sealed space 65B in which liquid and gas are accommodated. The substantially sealed space 65 </ b> B is occupied by the expansion / contraction body 71 in which gas is sealed and the liquid storage section 70 which is a part other than the expansion / contraction body 71, and has a substantially constant volume. As the liquid enters and exits the liquid storage unit 70, the air pressure in the telescopic body 71 increases and thereby the gas volume in the substantially sealed space 65B increases and decreases.

  The storage tank 61B is made of a plastic or metal material having airtightness and pressure resistance, and holds the liquid to which pressure is applied and the elastic body 71. The storage tank 61B is formed in a cylindrical shape having an opening 72 at one end and a bottom 73 at the other end, and the liquid is introduced into and discharged from the storage tank 61B through the opening 72. The stretchable body 71 is formed of a stretchable material that is formed in a substantially spherical shape, does not react with the amine donor supplied from the first introduction tube 22, and has a certain elastic force so that the volume of the stretchable body 71 is variable. . The gas sealed in the stretchable body 71 is made of a substance such as air that maintains a gaseous state in an environment where the first amplitude suppression unit 24B is used.

  The stretchable body 71 is formed of an elastomer such as rubber that expands and contracts according to the liquid to which pressure is applied in the liquid reservoir 70 and has a restoring force to restore the original shape. Has been. The elastic body 71 functions as a buffer material for absorbing the increased pressure in the sealed space 65B.

  As shown in FIG. 4, the stretchable body 71 is disposed inside the storage tank 61 </ b> B regardless of whether the stretched body or the contracted state. In addition, since the surface of the expansion / contraction body 71 is in contact with the side wall of the storage tank 61 </ b> B, the medicine enters the liquid storage unit 70 and the amount of liquid in the liquid storage unit 70 increases or the liquid storage unit 70 Even when the medicine is discharged and the amount of liquid in the liquid reservoir 70 decreases, the movement of the same trajectory is always repeated along the side wall of the reservoir 61B. In addition, the elastic body 71 is formed so as to come into contact with the side wall of the storage tank 61B, the medicine enters the liquid storage part 70, the amount of liquid in the liquid storage part 70 increases, the expansion body 71 is compressed, Even if it moves along the side wall of the storage tank 61B, the surface of the expansion-contraction body 71 contacts the bottom 73 of the storage tank 61B. For this reason, excessive movement of the expansion / contraction body 71 is prevented by the presence of the bottom 73, and the expansion / contraction body 71 repeats expansion and contraction while being held by the side wall of the storage tank 61B and the bottom 73. Therefore, by enclosing gas in the expansion / contraction body 71 and disposing the expansion / contraction body 71 in the storage tank 61B, the orientation of the first introduction pipe 22 and the first outlet pipe 25 connected to the storage tank 61B is increased. Even if it is changed or vibration is applied to the manufacturing apparatus 10 itself, the increased pressure in the storage tank 61B can be absorbed in a stable state.

  The first outlet pipe 25 and the first inlet pipe 22 are each connected to the opening 72 of the storage tank 61B. The liquid introduced from the first introduction pipe 22 is led out from the first lead-out pipe 25 as the volume in the sealed space 65 increases or decreases. When the chemical solution is discharged from the first pump 23, the elastic body 71 accommodated in the storage tank 61B is contracted to absorb the instantaneous discharge pressure of the sealed space 65B. When the discharge of the chemical liquid from one pump 23 is stopped, the chemical liquid is led out through the opening 72 by gradually expanding the air in the contracted elastic body 71. In the present embodiment, the first lead-out pipe 25 and the first introduction pipe 22 share the opening 72, but the present invention is not limited thereto, and may be connected to the storage tank 61B as separate pipes.

  The operation of the first amplitude suppression unit 24B will be described with reference to FIG. Since the second amplitude suppression unit 34B has substantially the same configuration as the first amplitude suppression unit 24B, only the operation of the first amplitude suppression unit 24B will be described.

  As shown in FIG. 4A, before the chemical solution is discharged from the first pump 23, the pressure applied to the sealed space 65B and the restoring force for returning to the original shape of the stretchable body 71 are balanced. .

  Next, when the chemical liquid is discharged from the first pump 23, as shown in FIG. 4 (2), the discharged chemical liquid passes through the first introduction pipe 22 and enters the sealed space 65B from the opening 72 of the storage tank 61B. Enter. Thereby, if the expansion-contraction body 71 is compressed, the expansion-contraction body will shrink | contract and the liquid in the sealed space 65B will increase. At this time, the elastic body 71 has a restoring force to return to the original shape.

  Next, when the first pump 23 performs inhalation, the supply amount of the chemical solution from the first pump 23 decreases, so that the contracted expansion / contraction body 71 is restored to its original shape by the restoring force as shown in FIG. The elastic body 71 starts to deform in order to return to step S3, and gradually pressurizes the liquid in the sealed space 65B. Thereby, the chemical | medical solution in sealed space 65B enters into opening 72 of storage tank 61B, is discharged | emitted to the merge part 42 side via the 1st derivation | leading-out pipe | tube 25, and the pressure concerning sealed space 65B and the origin of the expansion-contraction body 71 eventually. The state returns to the state of FIG. 4 (1) in which the restoring force to return to the shape of FIG.

  The restoring force for returning to the original shape of the stretchable body 71 is a passive action that accompanies increase / decrease of the liquid entering and discharging from the sealed space 65B, and therefore the speed of the restoring force is increased in the sealed space 65B. It is slower than the increase / decrease speed of the liquid discharged from the entrance and sealed space 65B. For this reason, the amplitude of the discharge amount of the chemical liquid can be suppressed as compared with the amplitude of the entry or discharge amount of the chemical liquid.

  As described above, even if the amplitude of the flow of the chemical liquid is generated as the first pump 23 and the second pump 33 are discharged and sucked, the first pump 23 and the second pump 33 are repeatedly expanded and contracted. The chemical solution having an amplitude smaller than the amplitude of the flow rate when the chemical solution is supplied from can be supplied. Thus, even when using a pump made with a simple configuration such as a diaphragm pump, plunger pump or bellows pump in which the amplitude of the flow rate of the chemical solution is generated by pulsation, an amino donor when producing a slime control agent And the fluctuation range of the mixing ratio of the oxidant donor can be reduced.
