  The present invention provides a treatment apparatus and a treatment method for imparting magnetic activity to a liquid and containing nanobubbles to produce nanobubble-containing magnetic active water, and then performing various treatments using the nanobubble-containing magnetic active water, and the nanobubble-containing magnetic active water. TECHNICAL FIELD The present invention relates to a nanobubble-containing magnetic active water production apparatus for producing a liquid.

  Conventionally, various processing apparatuses and processing methods exist for processing liquids for various purposes. That is, a processing apparatus and a processing method capable of producing various useful liquids or removing various substances from the liquids by performing chemical treatment, physical treatment, biological treatment, or the like on the liquid. Is conventionally used.

  For example, conventionally, facilities for removing organic substances and the like from liquids such as waste water or water have been used. Examples of the equipment include biological treatment equipment and physical treatment equipment. More specifically, examples of the biological treatment facility include various microorganism tanks. On the other hand, examples of the physical treatment equipment include an activated carbon adsorption tower.

  In the case of the activated carbon adsorption tower, the organic matter contained in the waste water or irrigation water is adsorbed by the activated carbon adsorption tower, and then the activated carbon is taken out from the activated carbon adsorption tower, and the organic matter is recovered from the activated carbon. As a result, organic substances are removed from waste water or irrigation water. On the other hand, in the case of a microbial tank, organic matter is taken into the metabolic pathway of the microorganism, and the organic matter is decomposed in the metabolic pathway.

  By the way, it has been conventionally known that bubbles having a small diameter have various physiological functions, and researches on techniques for producing such bubbles and their effects are now underway.

  The bubbles can be classified into microbubbles, micronanobubbles and nanobubbles according to their diameters. Specifically, the microbubble is a bubble having a diameter of 10 μm to several tens of μm at the time of its generation, the micro-nano bubble is a bubble having a diameter of several hundred nm to 10 μm at the time of its generation, and the nanobubble is Bubbles having a diameter of several hundred nm or less at the time of generation. Note that a part of the microbubble may be changed to a micro / nanobubble by the contraction movement after the generation. Nanobubbles have the property that they can exist in a liquid for a long period of time.

  For example, conventionally, various utilization methods of nanobubbles and various apparatuses utilizing nanobubbles are known (see, for example, Patent Document 1). More specifically, in Patent Document 1, nanobubbles exhibit surface-active action and bactericidal action by reducing buoyancy, increasing surface area, increasing surface activity, generating a local high-pressure field, or realizing electrostatic polarization. It is described. Furthermore, Patent Document 1 describes a technique for cleaning various objects and a technique for purifying polluted water using the surface-active action and bactericidal action of nanobubbles. Furthermore, Patent Document 1 describes a method for recovering fatigue of a living body using nanobubbles. In Patent Literature 1, nanobubbles are produced by electrolyzing water and applying ultrasonic vibration to the water.

  Conventionally, a method for producing nanobubbles using a liquid as a raw material is known (see, for example, Patent Document 2). In the liquid, the production method includes 1) a step of decomposing and gasifying a part of the liquid, 2) a step of applying ultrasonic waves to the liquid, or 3) a step of decomposing and gasifying a part of the liquid; A step of applying ultrasonic waves to the liquid. It is described that an electrolysis method or a photolysis method can be used as a step of decomposing and gasifying a part of the liquid.

Conventionally, a waste liquid treatment apparatus using microbubbles (ozone microbubbles) made of ozone gas has been used (see, for example, Patent Document 3). In the waste liquid treatment apparatus, microbubbles made of ozone gas are produced by mixing the ozone gas produced by the ozone generator and the waste liquid using a pressure pump. The microbubbles react with the organic matter in the waste liquid, so that the organic matter in the waste liquid is oxidatively decomposed.

  However, the above-described conventional processing apparatus and processing method have a problem that there are many operations that cannot be processed because their capabilities cannot be fully exhibited.

  For example, dioxins and organic fluorine compounds (for example, perfluorooctasulfonic acid (PFOS) or perfluorooctanoic acid (PFOA)) are chemically stable substances, and have heat resistance and chemical resistance (for example, acid resistance). ). Therefore, for example, organic fluorine compounds are widely used as industrial materials such as surfactants or antireflection films in semiconductor manufacturing. However, the more widely used organic fluorine compounds are, the more likely they are released to nature. As described above, since the organic fluorine compound is a chemically stable substance, once it is released into the natural world, it is not decomposed, which can cause serious environmental pollution. For example, organic fluorine compounds have been detected in polar bears, seals, and whales, and it has become clear that environmental pollution by organic fluorine compounds is becoming increasingly serious internationally.

  For example, when an organic fluorine compound or the like is to be treated using the conventional biological treatment facility, there is no microorganism that can efficiently decompose the organic fluorine compound. Therefore, there is a problem that a large amount of the organic fluorine compound cannot be treated.

  Moreover, when it is going to process an organic fluorine compound etc. using the said conventional physical processing equipment, for example, since it is necessary to replace | exchange frequently activated carbon, it has the problem that work is complicated, and activated carbon There is a problem that a lot of cost is required to reproduce the video. The physical treatment equipment is basically equipment for recovering the organic fluorine compound, and is not equipment for decomposing the organic fluorine compound. Therefore, when using the said physical processing equipment, there exists a problem that the further equipment (for example, apparatus for incineration at high temperature) for decomposing | disassembling an organic fluorine compound is required.

  In addition, when the bubbles are used, various organic substances can be decomposed by the bubbles, but a chemically stable substance such as an organic fluorine compound cannot be decomposed efficiently. Therefore, there is a problem that a large amount of the organic fluorine compound cannot be treated.

  Therefore, conventionally, a process of incinerating an organic fluorine compound at a high temperature of 1000 ° C. or higher is performed. In such a method, when a large amount of an organic fluorine compound is processed, a large amount of fuel is required. The carbon dioxide released has the problem of causing global warming.

2) Nanobubble-containing magnetic active water generates much more unstable free radicals than nanobubble-containing water due to the synergistic effect of magnetic force and nanobubbles. As a result, the nanobubble-containing magnetic active water has a strong oxidizing power. Therefore, if the nanobubble-containing magnetic active water is used as a pretreatment for various devices, the processing efficiency in various devices can be increased.
3) Magnetic active water containing nanobubbles affects the processing efficiency of chemical treatment, physical treatment, biological treatment, etc. more than nanobubbles.

For example, the liquid includes clean water, waste water (eg, organic fluorine compound-containing waste water), bath water (eg, therapeutic bath water), reuse water, culture fluid (eg, microorganism or cell culture fluid, fish Water used for aquaculture, water used for plant cultivation, etc.), chemicals, cosmetics, organic solvents, heavy oil, crude oil, or bioethanol can be used, but is not limited thereto.

  The liquid raw material stored in the front tank 18 is discharged into the tank 1 through a pipe 21 by a pump 19. Note that the amount of the liquid material discharged into the tank 1 is adjusted by a valve 20.

[2: Pre-processing section]
Hereinafter, the preprocessing unit 45 will be described.

  The pretreatment unit 45 includes a tank 1, a second magnetic active water preparation unit 38 (second activation means), and a nanobubble-containing magnetic active water generation unit 17. Each configuration will be described below.

[2-1: Tank]
First, the tank 1 will be described.

  The tank 1 includes a first tank 22 and a second tank 27, and the first tank 22 and the second tank 27 are connected to each other. The liquid raw material described above is discharged into the first tank 22. In the first tank 22, an air diffuser 24 connected to the second magnetic active water preparation unit 38 via a pipe 23 is provided. Then, the gas 25 (second gas) is discharged from the diffuser tube 24, and the gas 25 and the liquid material forming the water flow 43 are stirred in the first tank 22.

  As described above, the gas 25 and the liquid raw material are agitated in the first tank 22. As will be described later, the gas 25 is a gas imparted with magnetic activity. Therefore, by stirring the gas 25 and the liquid raw material, a liquid raw material imparted with magnetic activity can be produced. At this time, if a relatively large impurity is mixed in the liquid material, the gas 25 adheres to the surface of the impurity to form a complex. Since the buoyancy derived from the gas 25 attached to the surface acts on the complex, the complex accumulates in the vicinity of the surface of the liquid raw material stored in the first tank 22. As a result, relatively large impurities can be removed from the liquid source existing in the vicinity of the bottom of the first tank 22.

  At this time, the first tank 22 and the second tank 27 are preferably connected to each other through the vicinity of the bottom of the first tank 22. According to the above configuration, the liquid material from which relatively large impurities have been removed can be selectively taken into the second tank 27. And since a comparatively big impurity can be removed previously, the quantity of the substance which should be processed by the process part 28 etc. which are mentioned later can be reduced.

  It does not specifically limit as said gas, A well-known gas can be used suitably. For example, as the gas, air, ozone gas, carbon dioxide gas, oxygen gas, nitrogen gas, or the like can be used, but the gas is not limited thereto.

  In addition, the pipe 50 is provided with a second pipe diameter adjusting unit 31 (second pipe diameter adjusting means) that can change the size of at least a part of the inner air cross section of the pipe 50. preferable. According to the said structure, while being able to convert the gas which is a turbulent flow into a phase flow, the flow velocity of the gas introduce | transduced into the 2nd magnetic active water preparation part 38 can be adjusted. And thereby, a magnetic field can be equally applied with respect to gas in the 2nd magnetic active water preparation part mentioned later.

  In addition, it is preferable that the flow velocity of the gas introduced into the 2nd magnetic active water preparation part 38 is 10 m / sec or more. According to the said structure, the influence of a magnetic field can be efficiently performed with respect to gas.

  The said 2nd piping diameter adjustment part 31 should just be a thing which can change the magnitude | size of the at least one lumen cross section of the piping 50, The concrete structure is not specifically limited.

  For example, as shown in FIGS. 9A and 9B, the second pipe diameter adjusting portion 31 can be formed by a pipe having a cylindrical shape. As shown in FIG. 9A, a flange 30 and a flange 32 are provided at each end of the pipe 50.

The flange 32 provided to 50 and the flange 32 provided to the second pipe diameter adjusting unit 31 can be attached and detached. Accordingly, the second pipe diameter adjusting unit 31 connected between the end portions of the pipe 50 can be exchanged. At this time, a plurality of second pipe diameter adjusting portions 31 having different cylindrical shapes, that is, cylindrical shapes having different cross-sectional diameters are prepared, and a desired second pipe diameter adjusting portion 31 is selected from these. If the second pipe diameter adjusting unit 31 is connected between the ends of the pipe 50, the lumen cross section of at least a part of the pipe 50 can be changed to a desired size. In addition, according to the shape and magnitude | size of the cross section of the 2nd piping diameter adjustment part 31, the shape and magnitude | size of the flange 30 and the flange 32 can be selected suitably.

  When the 2nd piping diameter adjustment part 31 is formed by cylindrical piping, the length of the said 2nd piping diameter adjustment part 31 in the direction through which gas flows is not specifically limited, It can set suitably. For example, the length of the second pipe diameter adjusting portion 31 is preferably 10 times or more the diameter of an opening opened in the flange 36 described later. In addition, the length of the second pipe diameter adjusting unit 31 is more preferably 10 times or more the diameter of the transverse section of the second pipe diameter adjusting unit 31 having a cylindrical shape.

  According to the above configuration, after the gas introduced into the second pipe diameter adjusting unit 31 as a turbulent flow is reliably made into a phase flow, the gas can be discharged to the second magnetic active water preparation unit 38 side.

  The gas converted into the phase flow by the second pipe diameter adjusting unit 31 is introduced into the second magnetic active water preparation unit 38.

  The said 2nd magnetic active water preparation part 38 should just be a thing which can apply a magnetic field to gas, The concrete structure is not specifically limited. For example, as shown in FIG. 1, the flange 36 is provided at the end of the pipe 50, and the flange 42 is provided at the end of the pipe 23. In addition, a flange 36 is provided at one end of the second magnetic active water preparation unit 38, and a flange 42 is provided at the other end. And the said 2nd magnetic active water preparation part 38 can be provided between the said flange 36 and the flange 42 by fixing the said flanges 36 and the said flanges 42 with a volt | bolt etc.

  The said 2nd magnetic active water preparation part 38 has the flow path 37 (2nd flow path) for allowing gas to pass through. At least a part of the flow path 37 is sandwiched between a region functioning as the S pole of the magnet and a region functioning as the N pole of the magnet, thereby applying a magnetic field to the gas passing through the flow path 37. It becomes possible to apply.

  The shape of the cross section of the flow path 37 is not particularly limited and can be set as appropriate. The cross-sectional shape of the flow path 37 is preferably, for example, one having at least one pair of opposed surfaces (for example, a square or a rectangle). In addition, when the shape of the cross section of the said flow path 37 is square or a rectangle, for example, it is preferable that the three-dimensional shape of the said flow path 37 becomes a substantially flat plate shape.

  As an example, FIG. 10 shows a cross-sectional view of a second magnetic active water preparation unit 38 having a flow path 37 having a rectangular cross section. As shown in FIG. 10, the flow path 37 has a surface 60 (first surface) and a surface 61 (second surface) that face each other. A magnet S pole 40 is disposed on the surface 60 side, and a magnet N pole 39 is disposed on the surface 61 side. A magnetic field is formed between the S pole 40 and the N pole 39, and gas passes through the magnetic field. In other words, as shown in FIG. 1, the gas passes through the lines of magnetic force 41 formed between the S pole 40 and the N pole 39. The gas is given magnetic activity by passing through the magnetic field.

  The distance between the surface 60 and the surface 61 is not particularly limited, and can be set as appropriate. For example, the distance between the surface 60 and the surface 61 is preferably 30 mm or less. According to the said structure, magnetic activity can be efficiently provided with respect to gas.

  The magnetic flux density (residual magnetic flux density) in the flow path 37 is 350 millitesla (3500 gauss or more, more preferably 450 millitesla or more.

  The gas to which magnetic activity has been imparted as described above is discharged as the gas 25 into the first tank 22 as described above, and as a result, is stirred with the liquid raw material. And the liquid raw material to which magnetic activity was provided by this is introduce | transduced into the nanobubble containing magnetic active water generation part 17. FIG.

[2-3: Magnetic active water generating part containing nanobubbles]
Next, the nanobubble-containing magnetic active water generator 17 will be described.

  The nanobubble-containing magnetic active water generating unit 17 includes a pipe 2, a first gas shearing part 4 having a gas-liquid mixing circulation pump 3, a second gas shearing part 5, a third gas shearing part 14, a first pipe diameter adjusting part 34 ( A first pipe diameter adjusting means), a first magnetic active water preparation section 9 (first activation means), a pipe 7, and an electric needle valve 8.

  A pipe 2 and a pipe 7 are connected to the first gas shearing part 4. Then, a liquid (liquid raw material in the second tank 27) is supplied to the first gas shearing part 4 via the pipe 2 and a gas (first gas) is supplied to the first gas shearing part 4 via the pipe 4. Gas). And the said liquid and said gas are mixed and sheared in the said 1st gas shearing part 4, As a result, microbubble containing water is produced.

  The gas (first gas) is not particularly limited. For example, as the gas, air, ozone gas, carbon dioxide gas, oxygen gas, nitrogen gas, or the like can be used, but the gas is not limited thereto.

  The liquid is supplied into the first gas shearing section 4 by operating the gas-liquid mixing circulation pump 3. Further, the gas supply into the first gas shearing section 4 and the adjustment of the gas supply amount are adjusted by the opening / closing operation of the electric needle valve 8.

  The timing of the opening / closing operation of the electric needle valve 8 is not particularly limited. For example, first, by starting the operation of the gas-liquid mixing circulation pump 3, the liquid is introduced into the first gas shearing section 4 and the liquid is stirred. Thereafter, it is preferable that the electric needle valve 8 is opened after the time when the output of the gas-liquid mixing circulation pump 3 reaches the maximum value, thereby supplying the gas into the first gas shearing portion 4. It is more preferable to open the electric needle valve 8 after 60 seconds from the start of the operation of the gas-liquid mixing circulation pump 3 and thereby supply gas into the first gas shearing portion 4. .

  Although it is possible to open the electric needle valve 8 at the start of operation of the gas-liquid mixing circulation pump 3, in this case, the gas-liquid mixing circulation pump 3 causes a cavitation phenomenon. As a result, the gas-liquid mixing circulation pump 3 May be damaged. However, if it is the said structure, since it can prevent that the gas-liquid mixing circulation pump 3 raise | generates a cavitation phenomenon, it can prevent that the gas-liquid mixing circulation pump 3 is damaged as a result.

  The amount of gas supplied into the first gas shearing part 4 by opening the electric needle valve 8 is not particularly limited. For example, it is preferable to supply gas to the first gas shearing portion 4 at 1.2 liters / minute or less. If it is the said structure, a lot of nanobubble containing water can be produced efficiently.

  Next, a process of producing nanobubble-containing water by the nanobubble-containing magnetic active water generating unit 17 will be described. In general, the nanobubble-containing water is produced through two steps (a first gas shearing step and a second gas shearing step). Hereinafter, the first gas shearing process and the second gas shearing process will be described in more detail.

[2-3-1: First gas shearing process]
In the first gas shearing step, microbubble-containing water is produced from the gas and the liquid.

  In the first gas shearing process, in the first gas shearing section 4, the pressure of the mixture of the gas and the liquid is controlled hydrodynamically using the gas-liquid mixing circulation pump 3, and gas is supplied to the negative pressure section. Is inhaled. The “negative pressure part” means a region where the pressure is smaller than that of the surroundings in the mixture of gas and liquid. Then, fine microbubbles are generated by shearing the gas while moving the mixture at high speed to form a negative pressure portion. In other words, the liquid and the gas are effectively self-mixed and dissolved and pumped. Thereby, microbubble-containing water containing finer microbubbles can be formed.

Although it does not specifically limit as said gas-liquid mixing circulation pump 3, It is preferable that it is a pump of the high head of 40 m or more (pressure of 4 kg / cm < ² >). The gas-liquid mixing circulation pump 3 is preferably a two-pole pump with stable torque. According to the said structure, it is possible to apply a desired pressure with respect to the microbubble containing water in the 1st gas shearing part 4, As a result, the microbubble contained in microbubble containing water is sheared more finely be able to.

  Moreover, in the gas-liquid mixing circulation pump 3, it is preferable that the pressure of the pump is controlled. For example, it is preferable that the rotation speed of the gas-liquid mixing circulation pump 3 is controlled by a rotation control unit (not shown) such as an inverter. The rotation control unit can be further controlled by a sequencer (not shown). According to the said structure, it becomes possible to apply a desired pressure with respect to the microbubble containing water in the said 1st gas shearing part 4, As a result, the microbubble contained in microbubble containing water is made into a desired size. Can be aligned.

  Although the material of the said 1st gas shear part 4 is not specifically limited, It is preferable that they are stainless steel, a plastics, or resin. Of the above materials, stainless steel is most preferred. According to the said structure, while being able to prevent an impurity mixing in microbubble containing water, it can prevent that the 1st gas shearing part 4 vibrates.

  Moreover, the thickness (thickness of the partition wall) of the first gas shearing portion 4 is not particularly limited, but is preferably 6 mm to 12 mm. In general, if the thickness of the first gas shearing portion 4 is thin, the first gas shearing portion 4 vibrates due to the movement of the microbubble-containing water in the first gas shearing portion 4. That is, since the kinetic energy of the microbubble-containing water propagates to the outside as vibration and is lost, the high-speed flow motion of the microbubble-containing water decreases, and as a result, the shear energy decreases. However, according to the said structure, since the vibration of the 1st gas shearing part 4 can be prevented, a microbubble can be produced efficiently.

  Next, the mechanism by which the first gas shearing part 4 having the gas-liquid mixing circulation pump 3 generates microbubbles will be described in detail.

  First, in the said 1st gas shearing part 4, the mixed phase swirl | flow which consists of the liquid and gas which are the structural components of microbubble containing water is generated. Specifically, a wing called an impeller is rotated at an ultra high speed to generate a mixed phase swirl composed of a liquid and a gas. At this time, a gas cavity that swirls at a high speed is formed at the center of the first gas shearing portion 4.

  Next, the gas cavity is narrowed in a tornado shape by pressure to generate a rotating shear flow that swirls at a higher speed. At this time, gas is automatically supplied to the gas cavity using the negative pressure of the gas cavity. Then, the multiphase swirl is rotated while further cutting and crushing the microbubbles. In addition, the said cutting | disconnection and grinding | pulverization arises by the difference in the rotational speed of the gas-liquid two-phase fluid in the inside and outside of the exit of the 1st gas shearing part 4. FIG. The difference in rotational speed is preferably 500 to 600 revolutions / second.

  That is, in the first gas shearing part 4, a negative pressure part is formed by moving the microbubble-containing water at high speed by the gas-liquid mixing circulation pump 3, and the pressure of the microbubble-containing water is controlled hydrodynamically. The gas is supplied to the negative pressure part. As a result, the first gas shearing part 4 can generate microbubbles. In other words, the microbubble-containing water can be produced by using the gas-liquid mixing / circulation pump 3 to pump the liquid and gas while effectively self-mixing and dissolving them.

  The shape of the cross section of the lumen of the first gas shearing portion 4 is not particularly limited, but is preferably elliptical, and most preferably true round. Moreover, it is preferable that the lumen | bore surface of the said 1st gas shearing part 4 is formed by mirror surface finishing. According to the said structure, since the friction of the internal surface of the 1st gas shearing part 4 is small, while being able to rotate the mixture of gas and a liquid at high speed, a gas can be sheared efficiently. As a result, many fine microbubbles can be generated, and finally many nanobubbles can be generated.

  Moreover, it is preferable that a groove is provided on the inner surface (lumen surface) of the first gas shearing portion 4. Further, the number of the grooves is not particularly limited, but two or more grooves are preferably provided. Moreover, the said groove | channel should just have a concave shape formed on the internal surface of the 1st gas shearing part 4, The shape is not specifically limited. For example, the groove preferably has a depth of approximately 0.3 mm to 0.6 mm and a width of approximately 0.8 mm or less. According to the above configuration, the generation of the swirling turbulent flow of the mixture of the liquid and the gas in the first gas shearing section 4 can be controlled, so that many fine microbubbles can be generated and finally Many nanobubbles can be generated.

  Further, liquid is supplied to the first gas shearing section 4 through the pipe 2, and microbubble-containing water is discharged through the pipe 51. At this time, the area of the cross section of the lumen of the pipe for supplying the liquid (second pipe) is larger than the area of the cross section of the lumen of the pipe for discharging the microbubble-containing water (third pipe). preferable. According to the said structure, since the discharge pressure of microbubble containing water can be raised, a microbubble can be generated stably.

[2-3-2: Second gas shearing step]
In the second gas shearing step, nanobubble-containing water is produced from the microbubble-containing water produced in the first gas shearing step. More specifically, the microbubble-containing water produced by the first gas shearing section 4 is further sheared by the second gas shearing section 5, thereby producing nanobubble-containing water.

  In addition, the 3rd gas shearing part 14 can further be provided as needed. If the 3rd gas shearing part 14 is provided, while the magnitude | size of the nanobubble produced by the 2nd gas shearing part 5 can be made still smaller, the quantity of nanobubble can be increased. The installation position of the third gas shearing portion 14 is not particularly limited. For example, it can also be installed downstream of the first magnetic active water preparation unit 9 described later, and can also be installed upstream of the first magnetic active water preparation unit 9.

  Microbubble-containing water is pumped from the first gas shearing section 4 to the second gas shearing section 5 and further to the third gas shearing section 14 by the gas-liquid mixing circulation pump 3. When the microbubble-containing water is pumped from the first gas shearing section 4 to the second gas shearing section 5 and further to the third gas shearing section 14 through the pipe, the microbubble-containing water is pumped. It is preferable that the diameter of the pipe decreases gradually or stepwise in the direction. According to the above configuration, the microbubble-containing water can be thinned like a tornado while performing fluid motion at a higher speed. In other words, it is possible to generate a rotating shear flow that swirls at a higher speed. As a result, nanobubbles can be efficiently generated from microbubbles, and an ultra-high temperature extreme reaction field can be formed in nanobubble-containing water.

  When the above-mentioned extreme reaction field is formed, the water containing nanobubbles locally becomes a high-temperature and high-pressure state, and unstable free radicals are generated locally, and at the same time, heat is generated. A free radical is an atom or molecule having an unpaired electron, and attempts to stabilize by taking electrons from other atoms or molecules. Therefore, nanobubble-containing water containing free radicals exhibits a strong oxidizing power. Therefore, according to the said structure, organic substance etc. can be oxidatively decomposed | disassembled by the effect | action of a free radical.

  Moreover, it is preferable that the 2nd gas shearing part 5 and the 3rd gas shearing part 14 are formed with stainless steel, a plastics, or resin. According to the said structure, the material of the said 2nd gas shear part 5 and the 3rd gas shear part 14 can be selected according to the intended purpose of nanobubble containing water. For example, in the pharmaceutical industry, it is necessary to avoid contamination of drugs with impurities. In this case, if it is the said structure, since the possibility that the material of the 2nd gas shearing part 5 and the 3rd gas shearing part 14 will mix is low, manufactured nanobubble containing water is used for manufacture of a pharmaceutical, ie, pharmaceutical. Can do.

  Moreover, the shape of the cross section of the lumen of the second gas shearing portion 5 and the third gas shearing portion 14 is preferably an elliptical shape, and most preferably a true circle. According to the above configuration, since the resistance (friction) of the inner surfaces of the second gas shearing portion 5 and the third gas shearing portion 14 is small, the microbubble-containing water can be swirled at a high speed and the microbubble-containing water can be efficiently used. It can shear well and, as a result, many nanobubbles can be generated.

  Moreover, it is preferable that a hole is opened in the inner surfaces of the second gas shearing part 5 and the third gas shearing part 14. The diameter of the opening of the hole is not particularly limited, but is preferably 4 mm to 9 mm. According to the above configuration, the swirling motion of the bubble-containing water inside the second gas shearing portion 5 and the third gas shearing portion 14 can be controlled. That is, according to the said structure, generation | occurrence | production of the turning turbulent flow inside the said 2nd gas shearing part and a 3rd gas shearing part is controllable. As a result, nanobubbles can be stably generated by the second gas shearing portion and the third gas shearing portion.

  In addition, as a concrete structure of the gas-liquid mixing circulation pump 3, the 1st gas shearing part 4, the 2nd gas shearing part 5, and the 3rd gas shearing part 14 mentioned above, it is possible to use a commercially available thing. Although it does not specifically limit as each structure, For example, it is possible to use the Bavidas HYK type | mold made by Kyowa machine company.

  Next, the first pipe diameter adjusting unit 34 will be described.

  The nanobubble-containing water produced by the second gas shearing unit 5 is then introduced into the first pipe diameter adjusting unit 34.

  In the processing apparatus of the present embodiment, the first pipe diameter adjusting unit 34 adjusts the flow rate of the nanobubble-containing water introduced into the first magnetic active water preparation unit 9 described later, and the turbulence from the second gas shearing unit 5. The flow of water containing nanobubbles discharged as a flow is adjusted to a phase flow state. Thereby, the magnetic activity can be efficiently imparted to the nanobubble-containing water by the first magnetic active water preparation unit 9.

  In addition, it is preferable that the flow rate of the nanobubble containing water introduced into the 1st magnetic active water preparation part 9 is 2 m / sec or more. According to the said structure, it can influence the magnetic field efficiently with respect to nanobubble containing water.

  Below, the specific structure of the 1st piping diameter adjustment part 34 is demonstrated.

  In the processing apparatus of the present embodiment, the first pipe diameter adjusting unit 34 is provided in the pipe 51 that connects the second gas shearing unit 5 and the first magnetic active water producing unit 9.

  The first pipe diameter adjusting unit 34 is not particularly limited as long as it can change the size of the lumen cross section of at least a part of the pipe 51.

  For example, as shown in FIGS. 9A and 9B, the first pipe diameter adjusting portion 34 can be formed by a pipe having a cylindrical shape. As shown in FIG. 9A, a flange 33 and a flange 35 are provided at each end of the pipe 51. A flange 33 and a flange 35 are also provided at each end of the first pipe diameter adjusting section 34. Further, the flange 33 and the flange 35 are provided with bolt holes 65. And as shown in FIG.9 (b), the flange 33 provided in the piping 51 and the flanges 33 provided in the 1st piping diameter adjustment part 34, and piping by attaching | detaching a volt | bolt to the said bolt hole 65. The flange 35 provided to 51 and the flange 35 provided to the first pipe diameter adjusting unit 34 can be attached and detached. As a result, the first pipe diameter adjusting section 34 connected between the ends of the pipe 51 can be replaced. At this time, a plurality of first pipe diameter adjusting sections 34 having different cylindrical shapes, that is, cylindrical shapes having different cross-sectional diameters, are prepared, and a desired first pipe diameter adjusting section 34 is selected from these. If the first pipe diameter adjusting section 34 is connected between the end portions of the pipe 51, at least a part of the lumen cross section of the pipe 51 can be changed to a desired size.

  When the 1st piping diameter adjustment part 34 is formed by cylindrical piping, the length of the said 1st piping diameter adjustment part 34 in the direction through which nanobubble content water flows is not specifically limited, It can set suitably. For example, the length of the first pipe diameter adjusting unit 34 is preferably 10 times or more the diameter of an opening opened in the flange 6 described later. The length of the first pipe diameter adjusting section 34 is more preferably 10 times or more the diameter of the cross section of the first pipe diameter adjusting section 34 having a cylindrical shape.

  According to the above configuration, after the nanobubble-containing water introduced into the first pipe diameter adjusting unit 34 as a turbulent flow is reliably converted into a phase flow, the nanobubble-containing water is discharged to the first magnetic active water preparation unit 9 side. be able to.

  Next, the first magnetic active water preparation unit 9 will be described.

  In the processing apparatus of the present embodiment, the nanobubble-containing water that has passed through the first pipe diameter adjusting unit 34 is introduced into the first magnetic active water preparation unit 9.

  In the treatment apparatus of the present embodiment, the first magnetic active water preparation unit 9 applies a magnetic field to the nanobubble-containing water produced by the second gas shearing unit 5. As a result, activity (magnetic activity) as magnetic active water can be imparted to the nanobubble-containing water.

  Below, the specific structure of the 1st magnetic active water preparation part 9 is demonstrated.

  In the processing apparatus of the present embodiment, the first magnetic active water preparation unit 9 is provided between the second gas shearing unit 5 and the third gas shearing unit 14. In addition, as a position of the 1st magnetic active water preparation part 9, it is not limited to this. For example, the first magnetic active water preparation unit 9 can be provided upstream of the second gas shearing unit 5 and the third gas shearing unit 14. More specifically, for example, it is possible to provide the second gas shearing part 5 downstream of the first magnetic active water preparation part 9 and the third gas shearing part 14 further downstream of the second gas shearing part. It is.

  The said 1st magnetic active water preparation part 9 should just be a thing which can apply a magnetic field to the nanobubble containing water manufactured in the 2nd gas shear part 5, and the specific structure is not specifically limited. For example, as shown in FIG. 1, the first magnetic active water preparation unit 9 can be provided so as to be sandwiched between the flange 6 and the flange 12. As shown in FIG. 1, the flange 6 is connected to the end of the pipe 51, and the flange 12 is connected to the end of the pipe 13. And the said 1st magnetic active water preparation part 9 may be provided between the said flange 6 and the flange 12. FIG.

  The said 1st magnetic active water preparation part 9 has the flow path 26 for allowing nanobubble containing water to pass through. And at least a part of the flow path 26 is sandwiched between a region functioning as the S pole of the magnet and a region functioning as the N pole of the magnet, whereby the nanobubble-containing water passing through the flow path 26 It becomes possible to apply a magnetic field.

  The shape of the cross section of the flow path 26 is not particularly limited and can be set as appropriate. The cross-sectional shape of the channel 26 is preferably, for example, one having at least one pair of opposed surfaces (for example, a square or a rectangle). In addition, when the shape of the cross section of the said flow path 26 is square or a rectangle, it is preferable that the three-dimensional shape of the said flow path 26 becomes a substantially flat shape.

  As an example, FIG. 10 shows a cross-sectional view of the first magnetic active water preparation unit 9 having a flow path 26 having a rectangular cross section. As shown in the figure, the flow path 26 has a surface 62 (third surface) and a surface 63 (fourth surface) that face each other. The S pole 10 of the magnet is disposed on the surface 62 side, and the N pole 16 of the magnet is disposed on the surface 62 side. Then, a magnetic field is formed between the S pole 10 and the N pole 16, and the nanobubble-containing water passes through the magnetic field. In other words, as shown in FIG. 1, the bubble-containing water passes through the magnetic field lines 11 formed between the S pole 10 and the N pole 16. And magnetic activity is provided to nanobubble content water by passing through the inside of a magnetic field.

  That is, when the liquid passes through the magnetic field lines 11, a weak current is generated. Then, the bonds between the water molecules are broken by the action of a weak current, and as a result, the clusters (clusters of molecules) are subdivided. Since the water in which the clusters are subdivided has a high effect of absorbing oxygen in the gaps between the clusters, a large amount of oxygen is absorbed from the outside air and the dissolved oxygen concentration becomes high. At the same time, radicals can be generated in the liquid by the action of a weak current. As a result, if magnetic activity is imparted to the liquid, it becomes possible to generate active oxygen in the liquid. Therefore, the nanobubble-containing water having magnetic activity can have both the oxidation ability of free radicals derived from nanobubbles and the oxidation ability derived from the active oxygen, and the strong oxidation ability makes it difficult to decompose. Organic matter can also be decomposed.

  In the processing apparatus of the present embodiment, the nanobubble-containing magnetic active water produced by the first magnetic active water production unit 9 is introduced into the third gas shearing unit 14 via the pipe 13. As described above, in the third gas shearing portion 14, the nanobubbles are further sheared. As a result, the size of nanobubbles in the magnetic active water containing nanobubbles can be further reduced, and the amount of contained nanobubbles can be increased. In addition, since the detail of the 3rd gas shearing part 14 was already demonstrated, the description is abbreviate | omitted here.
