Apparatus and System for Producing Vapors Containing Microbubbles

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas-liquid mixing device, a pumping device, a bubble-refining device, and a system for producing a gas-liquid containing microbubbles, and more particularly, to refining bubbles in gas-liquid.

Background Art Conventionally, microbubble generators have been known for dissolving gases such as air and gas efficiently in water, other liquids, and the like, for example, purifying water quality to revive the water environment. In addition to large-scale water environments such as lakes, swamps, ponds, and rivers, microbubble generators have recently been required to be applied to small-scale water environments such as bathtubs and tap water. For example, Patent Document 1 discloses a microbubble generating device of a swing method. In the microbubble generating device described in Patent Literature 1, a high-speed swirl flow is generated in a gas-liquid more than a gas-liquid, and a swirling cavity made of a gas of negative pressure is formed at the center of the swirling flow by centrifugal action of the gas-liquid, and the high-speed swirl flow and the negative-pressure cavity of the gas-liquid are formed. The gas is sheared and microbubbled by the negative revolution speed difference. Therefore, in order to generate microbubbles, it is necessary to turn the gas liquid at high speed, and therefore, a large pump for pumping the liquid into the container at a high pressure, a large container for increasing the turning radius, and the like. Therefore, the microbubble generating device described in Patent Document 1 has been able to be used in a large-scale water environment, but has a problem in that it is difficult to be applied to a small-scale water environment, such as to a home water purifier, a shower head, a bath, or the like.

Embodiment 1-Gas-liquid Mixing Device

FIG. 1 is a view for explaining a gas-liquid mixing apparatus of a swinging system according to Embodiment 1 of the present invention, in which FIG. 1 (a) shows an appearance of the gas-liquid mixing apparatus 100, and FIG. 1 (b). Shows the structure of the Ib-Ib cross section of FIG. 1 (a), and FIG. 1 (c) shows the structure of the Ic-Ic cross section of FIG.

The gas-liquid mixing apparatus 100 includes a mixing container (base body) 101 for mixing liquid and gas having an inner wall and an outer wall, and a turning part (flow forming body) that is a substantially cylindrical body for turning liquid and gas ( 110, a gas introducing part 102 for introducing gas into the mixing container, a liquid introducing part 103 for introducing liquid into the mixing container, and a gas-liquid discharging part for discharging gas liquid from the inside of the mixing container 101; Have 104.

The means for introducing the gas into the gas introduction portion 102 may be self-contained or forced. In a preferred embodiment, the gas is introduced from the gas introduction section 102 in a self-contained manner inside the mixing vessel 101. In the case of self-sufficiency, there is no need to provide a drive source separately for the gas supply operation, and the apparatus can be miniaturized. Further, in the case of self-sufficiency, the amount of gas in accordance with the amount of the supply liquid introduced into the liquid introducing portion 103 is variable in accordance with the change in the amount of the supply liquid, so that it can always be adjusted appropriately and stably supplied. Furthermore, a control valve for adjusting the gas introduction amount may be provided.

In the case where the means for introducing the gas is forced, the gas introduction part may be introduced from the gas introduction part 102 shown in FIG. 1 and introduced from the conduit between the pump 200 and the bubble microfabricator 300 described later. May be introduced or introduced from both sides. In the case of forcibly introducing a large amount of gas, it is preferable to introduce the gas from the conduit between the pump 200 and the bubble refiner 300.

In a representative embodiment, the liquid introduced into the liquid introduction portion 103 may be, but is not limited to, tap water or pressurized water. The gas-liquid mixing device 100 of the present invention may further include a pressure reducing valve for coping with a change in the supply pressure of the liquid.

A plurality of different liquids may be introduced into the liquid introduction portion 103 of the gas-liquid mixing device 100 of the present invention. Here, "different liquid" means not only different kinds of liquids but also different supply pressures and sources. In the embodiment in which the first liquid and the second liquid are introduced into the liquid introduction portion 103, the gas-liquid mixing device 100 of the present invention includes a first conduit for introducing the first liquid and a second liquid for introducing the second liquid. A second conduit may be provided. By providing each of these pipe lines and further adjusting each pressure with a pressure reducing valve, it is possible to efficiently generate fine bubbles. For example, the first liquid is tap water, and the second liquid is pressurized water, but is not limited thereto.

The shape of the mixing container 101 can take any shape within a range that does not prevent the liquid introduced by the liquid introducing portion 103 from becoming a swirl flow by the turning portion. For example, a substantially cylindrical body may be sufficient, an approximately ellipsoid may be sufficient, and a substantially spherical body may be sufficient as it. That is, the shape of the mixing vessel may be such that its inner wall has a cross section (Ic-Ic cross section in Fig. 1B) that is orthogonal to the pivotal central axis of the swirl flow. In addition, the mixing vessel 101 may or may not have a diameter reduction portion 101b in which the inner wall thereof is reduced in diameter toward the gas-liquid discharge portion 104. In a preferred embodiment, as shown in Fig. 1A, the mixing container 101 has a cylindrical portion 101a and a diameter reducing portion 101b. This is because the angular velocity of the turning in the diameter reduction portion 101b is increased and the shear force of the gas liquid discharged from the discharge portion is increased accordingly, so that the division of bubbles is achieved. In one embodiment, the shape of the diameter reduction part 101b may be conical or hemispherical. In a preferred embodiment, as shown in Fig. 1A, the diameter reducing portion 101b is conical, but the present invention is not limited to this.

The revolving part 110 is accommodated in the cylindrical part 101a, and between the inner wall surface of the mixing container 101 and the outer circumferential surface of the revolving part 110, the revolving flow path Rp for flowing liquid and gas while turning is provided. Formed. A gas introduction part 102 is formed on the upper surface of the turning part 110, and a gas passage 111 is formed on the upper part of the turning part 110 to guide the liquid from the gas introduction part 102 to the turning path Rp. It is. At the upper portion of the cylindrical portion 101a, a liquid introduction portion 103 for introducing liquid into the swing passage Rp is formed. The shape of the revolving part 110 is not limited to the substantially cylindrical body in this embodiment, and if the liquid introduce | transduced by the liquid introduction part 103 turns into a swirl flow by the revolving part, it will be a substantially ellipsoidal cylinder, for example. It may be sufficient and may be a substantially spherical shape. That is, the shape of the turning part 110 should just be a shape in which the cross section (Ic-Ic cross section of FIG. 1 (b)) orthogonal to the pivot center axis of swirl flow was formed in substantially circular shape.

The surface of the turning part 110 is provided with at least one groove 121 which is a recessed part along the circumferential direction in the axial direction. The spacing between the groove 121 and the groove 121 and the number of the grooves 121 when the grooves 121 are provided in plural may be arbitrary. In the exemplary embodiment, as shown in FIG. 1B, three grooves 121 are formed at regular intervals in the axial direction, but the present invention is not limited thereto. In addition, the groove 121 may be formed spirally along the outer peripheral surface of the revolving part 110. In one embodiment, the shape of the groove 121 may take any shape. For example, in the cross section including the pivot center axis, for example, it may be rectangular, triangular or semi-circular. In a preferred embodiment, as shown in FIG. 1B, the groove 121 is a triangle in a cross section including a pivot center axis, but the present invention is not limited thereto.

The groove 121 includes a baffle 110b, which is at least one protrusion, on the circumference of the revolving part 110, that is, the revolving part main body 110a. The interval between the baffle 110b and the baffle 110b and the number of times of the baffle 110b when the plural baffles 110b are provided around the axis of the turning part main body 110a may be arbitrary. In an embodiment in which a plurality of baffles 110b are provided, a person skilled in the art can appropriately determine the interval between the baffles and the number of baffles based on the diameter of the turning part. When the hydraulic pressure of the liquid to be supplied is constant, if the diameter of the turning portion is too small, the circumferential speed becomes too fast, and the flow of liquid colliding with the baffle due to the action of the centrifugal force makes the swirl flow difficult to occur. In addition, since the gas is light, it is easily concentrated in the center of the turning portion, and the stirring ability to make bubbles into fine cells decreases. On the contrary, when the diameter of the turning portion is too large, the circumferential speed becomes slow and the swirl flow is less likely to occur, but the flow that collides with the baffle weakens, and the pressure difference between the swirl flow is small, so that the mixing capacity of gas and liquid tends to decrease. The size of the diameter of the turning portion can be appropriately selected by those skilled in the art based on the required flow rate and the flow rate of gas liquid. In a preferred embodiment, the distance between the baffle 110b and the baffle 110b is approximately equal to the distance between the distal end of the baffle 110b and the inner wall of the turning part main body 110a (± 10%).

In one embodiment, the distance between the baffle 110b and the baffle 110b may be about 10 mm to about 50 mm, about 15 mm to about 40 mm, or about 20 mm to about 30 mm.

In one embodiment, the longevity of the baffle 110b may be 1-20 pieces, 4-16 pieces, 6-14 pieces, or 10-12 pieces.

In the preferred embodiment, as shown in FIG. 1C, the baffle 110b is disposed at regular intervals around the axis of the pivoting unit main body 110a, but the present invention is not limited thereto.

In one embodiment, the shape of the baffle 110b can take an arbitrary shape as long as it is a shape in which bubbles are decomposed by colliding with the swirl flow swirled by the swing portion. For example, in the cross-sectional shape perpendicular to the axis of the turning part main body 110a, a flat plate shape may be sufficient and it may be curved. In a preferred embodiment, as shown in Fig. 1 (c), the flat plate is a cross-sectional shape perpendicular to the axis of the turning part main body 110a. The baffle 110b can be molded by various methods, for example, may be formed by introducing a material into the mold, or may be formed by machining the material.

In addition, the orientation of the baffle 110b (the inclination angle A shown in FIG. 1C) may take any orientation as long as the liquid introduced by the liquid introduction portion 103 is swirled by the turning portion. have. For example, the inclination angle A may be about 90 °, or may be less than 0 ° to 90 ° (beveled in the direction along the turning direction S), and greater than 90 ° to less than 180 ° (as opposed to the turning direction S). Inclination in the direction of the cross section). In one embodiment, the inclination angle A is about 30 ° to about 80 °, about 40 ° to about 80 °, about 50 ° to about 80 °, about 30 ° to about 70 °, about 40 ° to about 70 °, Or from about 45 ° to about 65 °, and from about 45 ° to about 65 ° is preferred for the generation and miniaturization of bubbles. Inclination angle A may be the same for every baffle, and may differ. In a preferred embodiment, as shown in Fig. 1C, the inclination angle A is about 60 ° in the direction along the turning direction S, but the present invention is not limited to this.

The inside of the diameter reduction portion 101b is a hollow region, and the diameter reduction portion 101b is a truncated cone-shaped cylinder whose diameter decreases toward the gas-liquid discharge portion 104, and the gas-liquid introduced into the diameter reduction portion 101b. Silver increases the angular velocity of the turning in the diameter reduction part 101b. At the lower end of the diameter reducing portion 101b, a gas-liquid discharging portion 104 for discharging gas-liquid from the inside of the mixing vessel 101 is formed.

Next, the operation will be described.

The gas Ar supplied to the gas-liquid mixing apparatus 100 is introduced into the swing passage Rp from the gas introduction portion 102 via the liquid passage 111. In addition, the liquid Wa supplied to the gas-liquid mixing apparatus 100 is supplied to the turning path Rp from the tangential direction of the outer peripheral surface of the turning part main body 110a via the liquid introduction part 103. The liquid Wa supplied to the turning passage Rp is mixed with the gas Ar ejected from the liquid passage 111 at the upper portion of the casing cylindrical portion 101a, and contains the liquid Wa containing the gas Ar. Flows toward the gas-liquid discharging part 104 while turning along the outer circumferential surface of the revolving part main body 110a as a (gas liquid M1).

The baffle 110b provided in the groove 121 of the turning part main body 110a while the gas liquid M1 flows toward the gas-liquid discharge part 104 while turning along the outer peripheral surface of the turning part main body 110a in this way. And the bubbles contained in the gas liquid M1 are decomposed smaller.

When the gas-liquid M1 which has passed through the turning path Rp of the case body cylindrical part 101a reaches the case body conical part (diameter reduction part) 101b, the inside diameter of the case body conical part 101b is gas-liquid discharged. Since it becomes smaller toward the part 104, the turning angular velocity increases, and the gas-liquid M1 approaches the inner circumferential surface of the diameter reduction part 101b, and negative pressure is generated in the center part of the diameter reduction part 101b. When gas-liquid M1 is discharged from gas-liquid discharge part 104, since a big shear force is generated by the flow of gas-liquid M1 whose rotational angular velocity was increased by the diameter reduction part 101b, gas-liquid M1 is carried out by the shear force. Bubble contained in) decomposes smaller.

According to the first embodiment, the gas-liquid mixing device 100 includes a mixing container (base body) 101 for mixing gas Ar and liquid Wa, gas Ar and liquid Wa. It is provided with a turning part (flow path forming body) 110 for turning the gas-liquid M1 to be made, and it flows, turning a liquid and gas between the inner wall surface of the mixing container 101, and the outer peripheral surface of the turning part 110. A turning flow path Rp for forming a groove, and a groove 121 along the circumferential direction is formed at regular intervals in the axial direction on the surface of the turning part 110, and the shaft of the turning part main body 110a is formed in the groove 121. Since the baffles 110b are arranged at regular intervals, the groove of the turning part main body 110a is on the way while the gas liquid M1 flows toward the gas-liquid discharging part 104 while turning along the outer circumferential surface of the turning part main body 110a. It collides with the baffle 110b provided in 121, and the bubble contained in gas-liquid M1 will decompose smaller. Thus, the gas-liquid mixing apparatus 100 of this invention is equipped with the protrusion part (baffle 110b) in the turning part 110, and can efficiently produce fine bubbles compared with the case where it is not provided with the protrusion part (baffle 110b). Since it can generate | occur | produce, it becomes possible to miniaturize a gas-liquid mixing apparatus and a micro bubble generation system. In addition, the gas-liquid mixing device of the present invention may have a new function of miniaturizing the bubbles contained in the mixed gas-liquid, in addition to the original function of the gas-liquid mixing device to produce gas liquid by mixing gas and liquid.

Embodiment 2-Pump Apparatus

FIG. 2 is a view for explaining a pump device according to Embodiment 2 of the present invention, in which FIG. 2A shows the appearance of the pump device 200 and FIG. 2B shows FIG. The structure of the IIb-IIb line cross section of (a) is shown, and FIG.2 (c) shows the structure of the IIc-IIc line cross section of FIG.2 (b).

The pump device 200 according to the second embodiment has a pump main body 200a and a pump driving unit 201a for driving the pump main body 200a, as shown in FIG. The pump main body 200a has a cylindrical case body (pump case body) 201, and the pump case body 201 includes a pump suction part 202 and a pump case body for sucking gas into the pump case body 201. The pump discharge part 203 which discharges gas liquid to the outside in the 201 is provided.

As shown in FIG.2 (b) and FIG.2 (c), in the pump case body 201, the pin rotating body (wing wheel) 211 which is a rotating part which rotates so that the sucked gas liquid may turn is provided, The pin rotating body 211 is provided to the pump driving unit 201a, which is a driving unit for rotating the pin rotating unit 211, through the rotating body driving shaft 201b.

The pin rotating body 211 includes an axial rotating plate 211a fixed to the rotating body drive shaft 201b, an opposing rotating plate 211b disposed to face the axial rotating plate 211a, an axial rotating plate 211a and an opposing rotating plate 211b. At least one centrifugal pin (211c) is installed between.

In one embodiment, the shape of the centrifugal pin 211c may take any shape within a range capable of giving centrifugal force to the gas liquid sucked from the pump suction part 202 and generating swirl flow. For example, in the cross-sectional shape perpendicular to the rotating body drive shaft 201b, it may be a flat plate shape or may be a curved plate shape having a predetermined radius of curvature. In a preferred embodiment, the centrifugal pin 211c is a curved plate having an arc shape as a cross-sectional shape perpendicular to the rotating body drive shaft 201b, as shown in Fig. 2C, but the present invention is not limited to this. Do not. In addition, in one embodiment, the shape of the centrifugal pin 211c may be flat along the axial direction of the rotating body drive shaft 201b, or may be a twisted spiral shape. In a preferred embodiment, the shape of the centrifugal pin 211c is helical along the axial direction of the rotating body drive shaft 201b. By doing so, the suction force of the gas liquid according to the pump device 100 can be further improved.

In an embodiment in which the plurality of centrifugal pins 211c are provided, the distance between the centrifugal pins 211c and the centrifugal pins 211c is about 10 mm to about 50 mm, about 15 mm to about 40 mm, or about 20 mm to about 30 mm. The present invention is not limited to this. Those skilled in the art can select an appropriate interval according to the size of the pump device 100, the output of the pump device 100 and the like.

In one embodiment, the longevity of the centrifugal pin 211c may be 1-20 sheets, 4-16 sheets, 6-14 sheets, or 10-12 sheets. When the centrifugal pins 211c are disposed at a distance of 10 to 12 sheets (12 sheets in the example of FIG. 2C) at intervals around the axis of the rotating body drive shaft 201b, finer bubbles can be effectively achieved.

In addition, the orientation of the centrifugal pin 211c (the inclination angle B shown in FIG. 2C) can take any orientation within a range capable of giving centrifugal force to the gas liquid sucked from the pump suction section 202. For example, it may be a direction perpendicular to the rotational direction of the rotating body drive shaft 201b (inclination angle B is about 90 °), or inclined (inclination angle B is greater than 0 ° to less than 90 °) in the direction along the rotation direction. The inclination angle B may be greater than 90 ° but less than 180 ° in a direction opposite to the rotational direction. In one embodiment, the inclination angle B is about 120 ° to about 170 °, about 130 ° to about 170 °, about 130 ° to about 160 °, about 120 ° to about 150 °, about 120 ° to about 140 ° Or, from about 130 ° to about 140 °. Inclination angle B may be the same for every centrifugal pin, and may differ. In a preferred embodiment, as shown in Fig. 2C, the inclination angle B is set to about 130 ° in the direction along the direction opposite to the rotational direction X of the rotating body drive shaft 201b. It is not limited.

The orientation (inclined angle B) of the centrifugal pin 211c is determined by the radius of curvature when the centrifugal pin 211c has a curved plate shape having a predetermined radius of curvature. If the radius of curvature (bevel angle B) is too large, the fluid pressure rises and the swirling velocity becomes faster, so that the bubbles can be efficiently miniaturized, but the cavitation is induced, thereby preventing the stable gas-liquid supply. There is also. On the other hand, if the curvature radius (tilt angle B) is too small, the fluid pressure is lowered and the turning flow rate is lowered. Therefore, the finer bubbles may be inefficient, but the occurrence of cavitation is suppressed and stable gas supply can be performed. have. Those skilled in the art can appropriately select the orientation (inclined angle B) of the centrifugal pins 211c based on the required efficiency of the microbubbles and the stability of the gas-liquid supply. For example, the size of the radius of curvature of the centrifugal pins 211c is about 1/4 to about 1/1, about 1/3 to about 3/4, or about 1/2 to about the size of the appearance of the impeller 212. About 2/3.

The arrangement of the centrifugal pins 211c can arrange any number at any position within a range capable of generating swirl flow by centrifugal force applied to the gas liquid sucked from the pump suction unit 202. For example, one centrifugal pin 211c may be arranged, a plurality of centrifugal pins 211c may be arranged at regular intervals in the circumferential direction of the rotating body drive shaft 201b, and a plurality of centrifugal pins 211c are provided. May be arranged at different intervals in the circumferential direction of the rotating body drive shaft 201b. In a preferred embodiment, as shown in Fig. 2C, four centrifugal pins 211c are arranged at regular intervals along the circumferential direction of the rotor drive shaft 201b, but the present invention is not limited thereto. Do not. The centrifugal pin 211c is a circular arc inside the pump case body 201 for the gas liquid introduced into the pin rotating body 211 from the pump suction part 202 when the rotating body drive shaft 201b is rotated in the direction of an arrow X. It moves toward the outer side of the pump case body 201 along the centrifugal pin 211c of a shape.

Furthermore, an impeller (baffle) 212 that is at least one protrusion is disposed along the inner circumferential surface of the pump case body 201. The shape of the impeller 212 can take any shape in the range which can collide with the gas liquid which turned to the outer side of the pump case body 201 by the centrifugal force by the centrifugal pin 211c. The shape of the impeller 212 is, for example, a cross-sectional shape perpendicular to the axis of the pump case body 201 and may be a flat plate shape or a curved plate shape having a predetermined radius of curvature. In a preferred embodiment, as shown in Fig. 2C, the cross section perpendicular to the axis of the pump case body 201 is a flat plate, but the present invention is not limited to this. In addition, in one embodiment, the shape of the centrifugal pin 211c may be flat along the axial direction of the rotating body drive shaft 201b, or may be a twisted spiral shape. In a preferred embodiment, the shape of the centrifugal pin 211c is helical along the axial direction of the rotating body drive shaft 201b. By doing in this way, the suction force of gas-liquid by the pump apparatus 100 can further be improved.

In addition, the orientation of the impeller 212 (the inclination angle C shown in FIG. 2C) may collide with the gas liquid that is turned toward the outside of the pump case body 210 by the centrifugal force along the centrifugal pin 211c. Arbitrary orientation can be taken in the range which exists. For example, the direction may be perpendicular to the rotational direction X (inclination angle C is about 90 °), may be inclined in the direction along the rotational direction X (inclination angle C is greater than 0 ° to less than 90 °), and may be rotated. You may make it incline (inclination-angle C more than 90 degree-less than 180 degree) in the direction opposite to the direction X. In one embodiment, the inclination angle C is about 30 ° to about 80 °, about 40 ° to about 80 °, about 50 ° to about 80 °, about 30 ° to about 70 °, about 40 ° to about 70 °, Or about 45 ° to about 60 °. Inclination angle C may be the same for every impeller 212, and may differ. In a preferred embodiment, as shown in FIG. 2C, the impeller 212 has an inclination angle C of about 60 ° in the direction along the rotation direction X, but the present invention is not limited thereto. When the inclination angle C is about 30 ° or less, the space formed by the pump case body 201 and the impeller 212 becomes too small, so that the swirl flow swiveled by the centrifugal pin 211c satisfactorily enters the space. It becomes difficult and it becomes impossible to generate | generate desired turbulence.

The orientation (inclined angle C) of the impeller 212 is determined by the radius of curvature when the impeller 212 has a curved plate shape having a predetermined radius of curvature. If the radius of curvature (angle of inclination C) is too large, the fluid pressure rises and the rotational flow velocity becomes high, so that the bubbles can be efficiently miniaturized. However, the phenomenon of cavitation may be induced, thereby preventing the stable gas-liquid supply. On the other hand, if the radius of curvature (tilt angle C) is too small, on the contrary, the fluid pressure is lowered and the turning flow rate is lowered, so that the bubbles may become inefficient, but the phenomenon of cavitation is suppressed, and stable gas liquid supply can be performed. have. Based on the required efficiency of the microbubbles and the stability of the gas-liquid supply, those skilled in the art can appropriately select the orientation (inclined angle C) of the impeller 212. For example, the size of the radius of curvature of the impeller 212 is about 1/4 to about 1/1, about 1/3 to about 3/4, or about 1/2 to about about the size of the appearance of the impeller 212. May be 2/3.

In one embodiment, the relationship between the orientation of the centrifugal pins 211c and the orientation of the impeller 212 can take any relationship. For example, the orientation of the centrifugal pin 211c and the impeller 212 may be the same, and the orientation of the worm shim pin 211c and the impeller 212 may be different. In a preferred embodiment, when the centrifugal pin 211c rotates and the tip of the centrifugal pin 211c and the tip of the impeller 212 face each other, the centrifugal pin 211c and the impeller 212 are approximately straight. By making this straight line, swirl flow can smoothly flow into the inner wall of the pump case body 201 and the space of the impeller 212.

Arrangement of the impeller 212 can arrange | position arbitrary numbers in arbitrary positions in the range which can collide with the gas liquid which turned toward the outer side of the pump case body 201 by the centrifugal force by the centrifugal pin 211c. Do. For example, one impeller 212 may be arranged, the plurality of impellers 212 may be arranged at regular intervals along the circumferential direction of the pump case body 201, and the plurality of impellers 212 are pumped. The case bodies 201 may be arranged at different intervals along the circumferential direction. In a preferred embodiment, as shown in Fig. 2C, ten impellers 212 are arranged at regular intervals along the circumferential direction of the pump case body 201, but the present invention is not limited to this. .

In one embodiment, the small clearance (clearance) between the centrifugal pin 211c and the impeller 212 can take any value. If the gap is made too small, the turning flow rate increases, but the discharged water amount decreases, so that the desired gas-liquid discharge amount cannot be secured. On the contrary, if the gap is made too large, a desired amount of gas liquid discharge can be ensured, but the turning flow rate is lowered, so that the desired turbulence cannot be obtained between the centrifugal pins 211c and the impeller 212, making it difficult to refine the bubbles. The gap between the centrifugal pin 211c and the impeller 212 is selected based on the conditions such as the required amount of gas liquid discharge and the microbubble diameter. For example, the distance of the gap is about 0.5 mm to about 5 mm, about 0.7 mm to about 3 mm, or about 1 mm to about 2 mm.

In the pump apparatus 200 having such a structure, the pin driving body 211, which is a rotating part of the pump main body 200a, is driven by the pump driving unit 201a, and the gas liquid M1 containing bubbles is pumped in the pump suction unit 202. In the state supplied from the pump case body 201, the gas-liquid M1 in the pump case body 201 rotates in the pump case body 201 by the rotation of the pin rotating body 211. Thus, when gas liquid M1 turns in the pump case body 201, based on the centrifugal force, gas liquid M1 in the pump case body 201 will turn inside the pump case body 201, and will be pump case body. It is pulled toward the inner wall surface side of the pump case body 201 from the center of 201, and will collide with the impeller 212 provided in the inner wall of the pump case body 201. As the gas liquid M1 collides with the impeller 212 as described above, the bubbles contained in the gas liquid M1 are divided into smaller parts. In addition, the gas-liquid present in the small gap between the centrifugal pins 211c and the impeller 212 receives the centrifugal force along the centrifugal pins 211c as the shear force, so that the bubbles are decomposed smaller. As described above, the pump device 200 of the present invention is provided with a protrusion (impeller 212) on the inner wall of the pump main body 200a, so that fine bubbles are more efficient than when the protrusion (impeller 212) is not provided. In this way, the pump device and the microbubble generation system can be miniaturized. Further, the pump apparatus 200 of the present invention has a new function of miniaturizing bubbles contained in the gas liquid in addition to the pump original function of sucking gas liquid and discharging the gas liquid to the outside.
