  According to the inventions described in Patent Documents 1 and 2, it is said that properties such as water and fats and oils can be modified to those suitable for various applications, but the generation of fine bubbles adopted in these inventions The fact is that the size of the bubbles formed by the means (diffuser or diffuser) is relatively large. For this reason, the liquid reforming action of the fine bubbles formed by the fine bubble generating means is insufficient.

  In addition, the invention described in Patent Document 1 uses ozone and ultraviolet rays that may adversely affect a living body, and therefore requires careful handling and is unusable. The invention described in Patent Document 2 includes an oxygen generator. Therefore, it is not suitable for general use. Furthermore, since the inventions described in the cited documents 1 and 2 are both complicated in configuration, they are difficult to use and have poor maintainability.

  The problem to be solved by the present invention is to provide a liquid processing apparatus that is easy to use and can efficiently modify the properties of the liquid.

The liquid processing apparatus of the present invention includes a storage tank capable of storing a liquid, a liquid supply unit that sucks the liquid stored in the storage tank and returns the liquid to the storage tank, and a liquid that is moved by the liquid supply unit. A fine bubble generator provided in the flow path,

Here, the “liquid” includes various liquids such as water and fats and oils, a mixed liquid composed of a plurality of liquid components, a liquid in which a non-gas component such as a gas or a solute is dissolved, and other various liquids.

  In such a configuration, when the liquid is fed into the fluid swirl chamber via the liquid introduction path by the liquid feeding means, the liquid flows along the direction in which the liquid is twisted with respect to the virtual center line of the fluid swirl chamber. Since it is fed into the swirl chamber, a swirl flow that rotates around the virtual center line is generated in the fluid swirl chamber, and a negative pressure cavity is formed along the virtual center line that is the center portion thereof. For this reason, gas (air in the atmosphere) is introduced into the fluid swirl chamber via a gas introduction path established in one partition wall of the fluid swirl chamber, and a gas-liquid swirl flow is formed in the fluid swirl chamber.

  This negative pressure cavity is also called vortex cavitation, but the tip of the grown vortex cavitation is shredded by the gas-liquid swirl flow, and becomes a fluid mixed with a large amount of small bubbles of small size, and the other partition wall of the fluid swirl chamber It is discharged into the liquid in the storage tank from the discharge port established in Thus, by discharging a large amount of fluid mixed with fine bubbles toward the liquid in the storage tank, the properties of the liquid can be efficiently modified. A liquid storage tank; liquid supply means for sucking the liquid in the storage tank and returning it to the storage tank; and a fine bubble generator provided in a flow path of the liquid moved by the liquid supply means. The simple configuration makes it easy to use.

  Here, a plurality of the fine bubble generators in which the swirling directions of the gas and liquid around the virtual center line in the fluid swirl chamber are different from each other can be provided. With such a configuration, from a plurality of fine bubble generators having different swirl directions of gas and liquid in the fluid swirl chamber, fluids mixed with fine bubbles having different swirl directions are discharged from the discharge port into the liquid in the storage tank. Since the liquid is discharged, the liquid can be modified more efficiently.

  In this case, a switching means for selectively supplying the liquid moving by the liquid feeding means to any of the plurality of fine bubble generators may be provided. With such a configuration, it is possible to discharge a fluid mixed with fine bubbles whose turning direction is limited to one of the right and left, into the liquid in the storage tank. it can.

  According to the present invention, it is possible to provide a liquid processing apparatus that is easy to use and can efficiently modify the properties of a liquid.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a vertical sectional view showing a schematic structure of a liquid processing apparatus according to a first embodiment of the present invention, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. 3 is a view of one part of the liquid processing apparatus shown in FIG. 4 is a cross-sectional view taken along line AA in FIG. 3, FIG. 5 is a cross-sectional view taken along line BB in FIG. 3, and FIG. 6 is a fine bubble generator constituting the liquid processing apparatus shown in FIG. It is a partially expanded sectional view of the vicinity.

  A liquid processing apparatus 10 shown in FIG. 1 includes a storage tank 1 that can store a liquid W, and a pump P that is a liquid feeding means for sucking the liquid W stored in the storage tank 1 and returning it to the storage tank 1 again. And two fine bubble generators MB1 and MB2 respectively connected to the two liquid introduction paths 18a and 18b branched from the flow path 18 of the liquid W moving by the pump P via the three-way valve 18v. . The storage tank 1 has a rectangular parallelepiped shape formed by four side plates 1a, 1b, 1c, 1d and a bottom plate 1e, and a detachable lid 10a is covered on the upper surface opening, and a fluid flows on the lower surface side of the bottom plate 1e. The upstream end of the path 18 and the upstream end of the liquid outflow pipe 2 are connected. An opening / closing stopper 2a is provided on the downstream side of the liquid outflow pipe 2. By opening / closing the opening / closing stopper 2a, the liquid W is discharged and stopped from the discharge port 2b. In addition, since the shape of the storage tank 1 is not limited to a rectangular parallelepiped shape, a cylindrical shape, a polygonal cylindrical shape, etc. are employable.

  In the storage tank 1, fine bubble generators MB1 and MB2 are respectively attached to positions on the outer surfaces of the opposing side walls 1a and 1b near the bottom plate 1e, and the cooling means 3 is disposed above these fine bubble generators MB1 and MB2. Yes. Moreover, gas introduction paths 14a and 14b for supplying air in the atmosphere to the fine bubble generators MB1 and MB2 are connected to the fine bubble generators MB1 and MB2, respectively, and the upstream side of the gas introduction paths 14a and 14b is an air supply pipe. 14 joins. A gas purifier AF is disposed in the middle of the air supply pipe 14.

  The pump P is driven by a motor (not shown), and its power source is obtained by connecting the plug 4a of the power cord 4 to a commercial power source. The pump P sends the liquid W sucked from the storage tank 1 via the flow path 18 to the fine bubble generators MB1 and MB2 via two liquid introduction paths 18a and 18b branched from the three-way valve 18v, respectively. To pay. In the middle of the power cord 4, a timer T for setting the operation time of the pump P and automatically stopping is provided. The cooler 3 is also operated by power supply from the power cord 4.

  Here, the structure and function of the fine bubble generators MB1 and MB2 will be described with reference to FIGS. As shown in FIG. 3, the fine bubble generators MB1 and MB2 are mirror-structured structures attached to the side plates 1a and 1b facing each other, and the constituent parts are the same. The bubble generator MB1 will be described, and the fine bubble generator MB2 will be denoted by the same reference numerals as the constituent parts of the fine bubble generator MB1 and description thereof will be omitted.

  As shown in FIG. 3, the fine bubble generators MB1 and MB2 are disposed on the outer surfaces of the side plates 1a and 1b of the storage tank 1, and the discharge ports 28 are formed in the through holes 1f and 1g provided in the side plates 1a and 1b. It is fixed in communication. Further, since the through holes 1f and 1g are opened at positions where their axial centers form the same straight line S, the fine bubble generators MB1 and MB2 are arranged on the same straight line S so as to face each other.

  As shown in FIGS. 3 to 5, the fine bubble generator MB1 includes a peripheral wall 25d that surrounds the virtual center line 25c, and partition walls 25a and 25b that are provided at both ends of the peripheral wall 25d in the virtual center line 25c direction. The fluid swirl chamber 25 formed in the above and the liquid provided in communication with the fluid swirl chamber 25 for introducing the liquid W into the fluid swirl chamber 25 along the direction of twisting with respect to the virtual center line 25c. The introduction path 18a (18b), the gas introduction path 14a (14b) established in one partition 25a of the fluid swirl chamber 25 for introducing gas (air) into the fluid swirl chamber 25, and the other of the fluid swirl chamber 25 And a discharge port 28 opened in the partition wall 25b. The liquid introduction path 18a (18b) communicates with the fluid swirl chamber 25 through the liquid introduction port 27, and the gas introduction path 14a (14b) communicates with the fluid swirl chamber 25 through the gas introduction port 26.

  As shown in FIG. 1, when the pump P is operated in a state where the liquid W is stored in the storage tank 1, the liquid W sucked from the storage tank 1 via the flow path 18 is supplied to the liquid introduction path 18a. And flows into the fluid swirl chamber 25 from the liquid inlet 27, and a swirl flow R is generated in the fluid swirl chamber 25 as shown in FIGS. A substantially spindle-shaped negative pressure cavity V appears along substantially the virtual center line of the swirl flow R, and one end of the negative pressure cavity V is a gas opened in the partition wall 25a of the fluid swirl chamber 25. Located near the inlet 26, the other end is located near the discharge port 28 provided in the partition wall 25b of the fluid swirl chamber 25, and the end of the negative pressure cavity V located near the discharge port 28 is constricted. It becomes a state.

  Since the negative pressure of the negative pressure cavity V appearing in the fluid swirl chamber 25 in this manner causes a negative pressure also in the vicinity of the gas inlet 26, the gas introduction path 14a (14b) is generated by the suction force resulting from this negative pressure. ) Air sucked from the atmosphere via the gas inlet 26 continuously flows into the negative pressure cavity V in the fluid swirl chamber 25 and swirls together with the liquid W introduced into the fluid swirl chamber 25. Stream R is formed.

  The air that has flowed into the negative pressure cavity V is entrained in the swirl flow R generated in the fluid swirl chamber 25 and discharged from the discharge port 28. At this time, the end of the negative pressure cavity V on the discharge port 28 side is threaded by the swirl flow R to become fine bubbles NB, and becomes a fluid mixed with the fine bubbles NB together with the liquid W forming the swirl R. And it passes through the through-hole 1f (1g) and is discharged into the storage tank 1.

  The fluid mixed with the fine bubbles NB discharged into the storage tank 1 diffuses into the liquid W, and can supply and dissolve oxygen or nitrogen contained in air in the atmosphere into the liquid W. . By continuing such a process for a predetermined time set by the timer T, the properties of the liquid W can be modified. The modified liquid W can flow out from the discharge port 2b by opening the opening / closing stopper 2a. Since the liquid processing apparatus 10 can be used only by operating the pump P after removing the lid 10a shown in FIG. 1 and injecting the liquid W into the storage tank 1, the usage is also very simple.

  In the liquid processing apparatus 10 of the present embodiment, air in the atmosphere is supplied to the fine bubble generators MB1 and MB2, but the present invention is not limited to this. By supplying other gases, Various gases other than air can be supplied and dissolved in the liquid W. In addition, a plurality of types of gases can be supplied and dissolved in the liquid W by supplying different types of gases to the fine bubble generators MB1 and MB2.

  On the other hand, in the fine bubble generators MB1 and MB2, air is introduced from one end of the negative pressure cavity V appearing in the fluid swirl chamber 25 and mixed with the fine bubbles NB toward the extending direction of the other end. Release fluid. For this reason, this negative pressure cavity V continues to exist stably near the virtual center line 25c of the fluid swirl chamber 25, and both ends thereof are also stably located near the gas inlet 26 and the outlet 28, respectively. Therefore, the negative pressure cavity V does not contact the inner surface of the fluid swirl chamber 25 and the like, and cavitation erosion does not occur in the fine bubble generators MB1 and MB2, so that the durability is excellent.

  Further, as shown in FIGS. 3 to 5, the fine bubble generators MB1 and MB2 have a simple structure in which a liquid introduction port 27, a gas introduction port 26, and a discharge port 28 are opened in a fluid swirl chamber 25 having a substantially cylindrical shape. Therefore, it is easy to handle, and since there are no fine channels that are likely to be clogged with foreign matter that flows in with the liquid W or air, there are few troubles and periodic maintenance is unnecessary.

  Further, as shown in FIG. 6, the gas introduction port 26 opened in the partition wall 25 a of the fluid swirl chamber 25 is disposed so as to protrude inward along the virtual center line 25 c of the fluid swirl chamber 25, and the fluid swirl chamber A smoothly continuous concave curved surface 21 is provided between the peripheral wall 25d of 25 and the gas inlet 26. Therefore, the negative pressure cavity V continues to exist stably in the vicinity of the imaginary center line 25c of the fluid swirl chamber 25, and both ends thereof are also stably positioned in the vicinity of the discharge port 28 and the gas inlet 26.

  As described above, the gas inlet 26 is disposed so as to protrude to the inside of the fluid swirl chamber 25 and the concave curved surface 21 is provided, whereby the end of the negative pressure cavity V on the gas inlet 26 side moves irregularly. Can be prevented. Therefore, cavitation erosion or the like does not occur in the partition walls 25a and 25b of the fluid swirl chamber 25, and excellent durability can be obtained. As shown in FIGS. 3 and 6, a preliminary swirling portion 25 p having a larger inner diameter than other regions is provided in a region near the partition wall 25 b of the fluid swirl chamber 25. For this reason, the liquid W introduced from the liquid inlet 27 can be once rectified in the preliminary swirl unit 25p and then introduced into the entire fluid swirl chamber 25. Accordingly, the pressure fluctuation of the liquid W introduced from the liquid inlet 27 is buffered, and the movement of the negative pressure cavity V due to the pressure fluctuation can be prevented, which is effective in preventing cavitation erosion.

  Further, as shown in FIG. 6, in the fine bubble generators MB1 and MB2, the opening area of the liquid introduction port 27 is larger than the opening area of the discharge port 28, so that the liquid fed into the fluid swirl chamber 25 is supplied. The outlet of the fluid mixed with the fine bubbles NB is smaller than the inlet of W. Accordingly, the fluid pressure in the fluid swirl chamber 25 is increased by the pressure of the liquid W fed by the pump P, and the flow of fluid mixed with the fine bubbles NB discharged from the discharge port 28 is increased. The liquid W can be vigorously stirred. For this reason, the circulation of the liquid W in the storage tank 1 becomes favorable, and the reformed state of the liquid W can be made uniform.

  Furthermore, in the fluid swirl chamber 25 of the fine bubble generators MB1 and MB2 constituting the liquid processing apparatus 10, swirl flows R having opposite rotation directions are generated as shown in FIGS. That is, a clockwise swirling flow R is generated toward the discharge port 28 in the fluid swirl chamber 25 of the fine bubble generator MB1 shown in FIG. 4, and the fluid swirl chamber 25 of the fine bubble generator MB2 shown in FIG. Produces a counterclockwise swirling flow R toward the discharge port 28. Therefore, when both of the fine bubble generators MB1 and MB2 are operating, the fluid mixed with the fine bubble NB discharged from the fine bubble generators MB1 and MB2 is the same around the straight line S as shown in FIG. The liquid W in the storage tank 1 is diffused while turning in the direction.

  On the other hand, if the three-way valve 18v shown in FIG. 1 is operated so that the liquid W is supplied to only one of the fine bubble generators MB1 and MB2, only the clockwise swirling flow R or the counterclockwise swirling flow is set. A fluid mixed with fine bubbles NB formed only by R can be discharged into the liquid W in the storage tank 1.

  In addition, since the number of arrangement | positioning, arrangement | positioning position, etc. of micro bubble generator MB1, MB2 are not limited, For example, as shown in FIG. 2, micro bubble generator MB1, MB2 can also be attached to side wall 1c, 1d. Further, since the shape and size of the storage tank 1 are not limited, the horizontal cross-sectional shape may be a polygonal or circular storage tank, and a plurality of fine bubble generators MB1 and MB2 may be arranged on the side wall.

  Since the use of the liquid treatment apparatus 10 is not limited, the liquid treatment apparatus 10 can be used in various fields. For example, the liquid treatment apparatus 10 can be used as a drinking water reforming apparatus for general households. In this case, if the well water which is the liquid W to be treated is put into the storage tank 1 and the pump P is operated for a predetermined time and the above-described treatment is performed, the well water can be greatly modified. When the modified water obtained by this treatment is used for beverages, it is delicious and effective for health promotion. When the modified water is used for cooking rice and other cooking, the flavor and taste of rice and dishes are improved. Moreover, when the modified water was used as a lotion, the skin was moisturized and the effect of removing the makeup was improved. Moreover, the liquid processing apparatus 10 can also be used for the modification of water for various food processing, and the food produced and manufactured using the water after the modification has a taste, flavor, The texture and other quality are improved.

  The reason why the above-described effects can be obtained by treating well water with the liquid treatment apparatus 10 is unclear, but that the dissolved matter in the well water is ionized, the modification action by ultrasonic waves generated when the microbubbles NB burst, It is estimated that it may be due to an increase in dissolved oxygen concentration or dissolved nitrogen concentration.

  Next, second and third embodiments of the present invention will be described with reference to FIGS. FIG. 7 is a vertical sectional view showing a schematic structure of a liquid processing apparatus according to a second embodiment of the present invention. FIG. 8 is a partially enlarged sectional view in the vicinity of a fine bubble generator constituting the liquid processing apparatus shown in FIG. 9 is a vertical sectional view showing a schematic structure of a liquid processing apparatus according to a third embodiment of the present invention, FIG. 10 is a partially enlarged sectional view in the vicinity of a fine bubble generator constituting the liquid processing apparatus shown in FIG. These are the vertical cross sections which show schematic structure of the liquid processing apparatus which is 4th Embodiment of this invention. 7 to 11, the parts denoted by the same reference numerals as those in FIGS. 1 to 6 are parts having the same structure and function as the constituent parts of the liquid processing apparatus 10 described above, and description thereof is omitted.

  The liquid processing apparatus 40 shown in FIG. 7 has a storage tank 41 capable of storing the liquid W, and a pump P2 for sucking the liquid W stored in the storage tank 41 via the flow path 48 and returning it to the storage tank 41 again. A fine bubble generator MB1 connected to the liquid introduction path 18a provided on the downstream side of the pump P2, a pump P1 for supplying the liquid W into the storage tank 41, and the modified storage tank 41 And a pump P3 for feeding the liquid W to another location. The fine bubble generator MB1 is installed at a substantially central portion of the upper surface of the bottom plate 41b in the storage tank 41, and a sensor 42 for detecting the liquid level of the liquid W is disposed above the storage tank 41. The liquid supply pipe 43 connected to the downstream side of the pump P <b> 1 is piped upward along the inner surface of the side wall 41 a of the storage tank 41, and its tip portion curves in an inverted U shape at a position protruding from the liquid level of the liquid W. is doing.

  When the pump P2 is operated in a state where the liquid W is stored in the storage tank 41, the liquid W sucked from the storage tank 41 via the liquid introduction path 18 generates fine bubbles via the liquid introduction path 18a. As shown in FIG. 8, the fluid flows into the fluid swirl chamber 25 from the liquid inlet 27 of the fine bubble generator MB 1, and a swirl flow R is generated in the fluid swirl chamber 25. As in the previous case, the fluid mixed with the fine bubbles NB formed by the swirling flow R passes through the discharge port 28 and is discharged into the liquid W in the storage tank 41, whereby the liquid W is reformed. Is called.

  The reformed liquid W in the storage tank 41 is supplied to another place by the pump P3 as necessary. When the liquid W in the storage tank 41 decreases and the liquid level falls, the sensor 42 detects this and the pump P1 is activated, and the new liquid W enters the storage tank 41 via the liquid supply pipe 43. Supplied. When the liquid W in the storage tank 41 reaches a predetermined amount, the sensor 42 detects that and stops the pump P1. Such start / stop of the pump P1 and start / stop of the pump P2 are performed by a control circuit (not shown) built in the timer T.

Since the use of the liquid processing apparatus 40 is not limited, it can be used in various fields. However, since a relatively large amount of the liquid W can be processed, it can be suitably used as, for example, a livestock water reforming apparatus. . When the well water was modified by the liquid treatment device 40 and given to the pigs in the pig farm, the following effects were obtained.
(1) The breeding days were shortened to about 90%.
(2) Feeding amount was reduced to about 90%.
(3) The accident rate decreased from 5% to less than 1%.
(4) The amount of 18 kinds of free amino acids in 100 g of pork increased by about 30%.
(5) The meat quality was improved to a free amino acid ratio with a lot of umami and sweetness components.
(6) In the fatty acid composition, the meat had a high ratio of linoleic acid and linolenic acid.

  The reason why the various effects described above can be obtained by treating well water with the liquid treatment apparatus 40 is unknown at this time, and its elucidation is a future problem.

  Next, in the liquid processing apparatus 50 shown in FIG. 9, the liquid W accommodated in the storage tank 51 is sucked by the pump P and sent to the fine bubble generator MB1, and the fine bubbles NB formed by the fine bubble generator MB1. By discharging the mixed fluid into the liquid W in the storage tank 51, the properties of the liquid W1 in the container Q immersed in the liquid W can be modified. The use of the liquid processing apparatus 50 is not limited. For example, when the container Q (pet bottle) containing the liquid (water) W1 is immersed in the liquid W in the storage tank 51 and processed, the processed liquid (water) ) W1 is modified, delicious when drunk, and effective for health promotion. Moreover, it can be used suitably also as a lotion.

  Since the material of the container Q that can be processed in the liquid processing apparatus 50 is not limited to PET (polyethylene terephthalate), PE (polyethylene), PVC (polyvinyl chloride), PMMA (polymethyl methacrylate), PP (polypropylene), PA ( Liquids contained in various synthetic resin containers such as nylon, PS (polystyrene), PMP (polymethylpentene), PVDC (polyvinylidene chloride), and PC (polycarbonate) can be similarly treated.

  The reason why the liquid W1 in the container Q in a non-contact state with the liquid W is reformed by modifying the liquid W with the fluid mixed with the fine bubbles NB formed by the microbubble generator MB1 is unknown at this time. However, it is presumed that this is a modification action by ultrasonic waves generated when the microbubbles NB burst.

  Further, in the liquid processing apparatus 50, in order to avoid the bottom surface of the container Q immersed in the liquid W from coming into close contact with the top surface of the bottom plate 51b in the storage tank 51, a plurality of support columns 51c erected on the top surface of the bottom plate 51b. A horizontally supported support member 51a is provided. As shown in FIG. 10, since the support member 51a has liquid permeability and air permeability, the support member 51a is discharged through the discharge hole 28 of the fine bubble generator MB1 and the through hole 51h provided in the bottom plate 51b. The fluid mixed with the fine bubbles NB passes through the support member 51a and diffuses into the liquid W.

  Furthermore, since the liquid processing apparatus 50 can treat the container Q such as a plastic bottle containing water by immersing it in the liquid W as it is, it is easy to use, hassle-free, and is hygienic. When processing drinking water, it can be used conveniently.

  Next, the liquid processing apparatus 60 shown in FIG. 11 has a structure in which the liquid outflow pipe 2 and the opening / closing plug 2a are omitted from the liquid processing apparatus 10 shown in FIG. Since the fluids mixed with the fine bubbles NB formed by the fine bubble generators MB1 and MB2 are discharged from the side plates 1a and 1b into the liquid W, respectively, the container Q containing the liquid W1 is placed on the upper surface of the bottom plate 1e. Can do.

  Since the liquid processing apparatus 60 can treat the container Q containing the liquid W1 by immersing it in the liquid W as it is, the same effects as the liquid processing apparatus 50 described above can be obtained. In addition, although the liquid processing apparatuses 50 and 60 immerse and process the container Q containing the liquid W1 in the liquid W in the storage tanks 51 and 1 as it is, it is not limited to this usage. It is also possible to directly introduce the liquid into the storage tanks 51 and 1 and perform the reforming process, thereby obtaining the same effects as the liquid processing apparatuses 10 and 40.

  Note that the liquid processing apparatus of the present invention is not limited to the above-described embodiment, and the liquid to be processed is not limited to water, so liquids other than water, for example, liquid fuel, alcoholic beverages, liquid seasonings, Cooking oils and fats can also be processed. Moreover, gas other than air, for example, ozone, carbon dioxide, etc., can be supplied to the fine bubble generators MB1 and MB2 of the liquid processing apparatuses 10 and 40 to generate fine bubbles NB. For example, when water is put into the storage tanks 1 and 41 of the liquid processing apparatuses 10 and 40 and ozone is supplied to the fine bubble generators MB1 and MB2, bacteria in the water can be sterilized. Water can be generated.

  INDUSTRIAL APPLICABILITY The present invention can be widely used in various industrial fields as means for modifying drinking water, livestock water, industrial water, food production water, liquid seasonings, oils and fats.
