[Prior art]
Recently, in order to improve the living environment from the viewpoint of environmental conservation, the quality of water such as lakes and swamps is often purified. Various water purification apparatuses for this purpose have been proposed. Conventionally, there are many convection types that are accompanied by circulating aeration. This method is a method of pumping water from a lake or the like with a pump, and mixing the element for purifying water into the water to return it to the target lake.
[0003]
In dams, reservoirs, lakes, etc., water quality is often deteriorated due to lack of oxygen, and there are many ways to increase the amount of dissolved oxygen and return the lakes to their original state. In this connection, the present applicant also generates cavitation according to Japanese Patent Application Laid-Open No. 2000-563 and the like, and purifies the cavitation flow by degassing, mixing, stirring, sterilizing, insecticidal, decomposing, emulsifying, etc. Proposed method. Recently, environmental standards have become stricter, and a more efficient purification method is desired.
[0004]
[Problems to be solved by the invention]
The purification method by cavitation is particularly effective for sterilization, and is effective in destroying plankton, parasites, and parasite eggs in water. When the purification apparatus according to this method is applied to, for example, a seawater fish farm and used for seawater purification, oxygen in the water inevitably becomes insufficient only by cavitation. Therefore, in Japanese Patent Laid-Open No. 2000-563, FIG. As shown, a method has been proposed in which an ejector is attached to an outlet of a flow that has generated a cavitation jet to purify seawater by allowing air to self-suck.
[0005]
In the apparatus according to this method, cavitation generating means for injecting pressurized liquid to generate cavitation, and the liquid injected from the cavitation generating means is formed as a jet flow, and the jet flow is converted into a dynamic vortex flow. A turbulent flow generating means having a substantially closed space and a discharge port for discharging liquid from the turbulent flow generating means are provided.
[0006]
Schematically described in FIG. 12, the turbulent flow generation box 61 has a flat rectangular shape, which is an apparatus applied to seawater reforming. The turbulent flow generation box 61 has a turbulent flow generation chamber 62, which forms a curved portion 63 for facilitating cavitation and smoothing the flow of the vortex flow. The pressurized seawater is injected into the turbulent flow generation chamber 62 through the injection nozzle 66 from the direction of the arrow. The seawater injected into the turbulent flow generation chamber 62 generates turbulent flows such as cavitation bubbles and vortex flows.
[0007]
By this cavitation action, ammonia, carbon dioxide, chlorine, oxygen, etc. in the seawater are degassed. Furthermore, it destroys, sterilizes and kills fish parasites, parasite eggs, larvae, Escherichia coli, etc. in seawater. The cavitation-treated seawater sucks air in the atmosphere from the discharge nozzle 69 through the air pipe 71 with discharge negative pressure and is mixed with seawater.
[0008]
The apparatus having such a configuration is more effective than before, but this ejector system that sucks air through the air pipe 71 is not necessarily efficient in increasing the dissolved oxygen concentration because the gas dissolution efficiency is low. However, a more efficient method was desired. The present invention is a further development and improvement of this apparatus, which has been made based on the above-mentioned social environment and technical background, and achieves the following objects.
[0009]
An object of the present invention is to provide a liquid quality reformer that efficiently purifies water by destroying and sterilizing underwater organic substances such as plankton by increasing cavitation bubbles in a jet generating chamber.
Another object of the present invention is to provide a low-cost liquid quality reforming apparatus that can make the jet flow into fine bubbles for any water quality, increase the dissolved oxygen concentration, and perform efficient purification. .

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front sectional view of a liquid purification device 1 which is an embodiment of the liquid quality reforming apparatus of the present invention, and FIG. 2 is a side sectional view thereof. The details of the conditions of the nozzle shape for generating cavitation are described in Japanese Patent Application Laid-Open No. 2000-563, and are well known in other documents, and therefore detailed description thereof is omitted.
[0019]
The basic part of the liquid purification device 1 of the present embodiment includes a jet generation box 2 (also referred to as a jet generation box in this specification), a first nozzle 3 that injects liquid and generates cavitation, and a jet flow. It is comprised from the 2nd nozzle 6 (it is also called a "fluid supply pipe") which is provided in the side surface 4 of the generation box 2, and supplies the fluid toward the jet 5 injected into the jet generation box 2.
[0020]
In the present embodiment, the first nozzle 3 has a step in the ejection direction, and generates cavitation when the liquid is ejected. The system of the liquid purification device 1 according to the present embodiment supplies a liquid supply device 7 for supplying a liquid to the jet nozzle 2 and a fluid or gas to the second nozzle 6. A fluid supply device 8 is connected via a pipe. Further, the jet generated in the jet generating box 2 is accompanied by vortex and formed into fine bubbles, including debris destroyed and sterilized by cavitation, and discharged from the discharge port 9 to the seawater outside the jet generating box 2. Discharged.
[0021]
The internal space V in the jet flow generation box 2 is generally a flat rectangular parallelepiped. The physical and geometric significance of flatness will be described in detail later. The jet generating box 2 having a longitudinal center line CL passing through the center point of the internal space V as an axial center line has a substantially rectangular parallelepiped appearance, and includes a six-sided wall. 3 and 4 show cross sections representing the internal space of the jet generating box 2 of FIG. 4 is a cross-sectional view taken along line XX of FIG. A jet hole 10 having a diameter D1 is provided on one wall surface of the jet generation box 2.
[0022]
The jet hole 10 coincides with the cavitation generating part. The axial center line of the jet hole 10 which is a cavitation generating part coincides with the longitudinal center line CL. A high-pressure liquid is supplied from the liquid supply device 7 to the axial liquid introduction hole 11 communicating with the jet hole 10. The internal space V into which the jet 5 is injected has a width W shown in the figure, a height H, and a length L1 is not particularly defined. The length direction of the internal space V is defined as the axial direction of the jet hole 10.
[0023]
Further, a fluid for supplying a fluid in which the height H of the internal space V, the diameter D1 of the jet hole, and the diameter D2 of the axial liquid introduction hole 11 are further pressurized in a direction perpendicular to the flow direction of the jet. A diameter D3 of the supply hole 12 (also referred to as “second nozzle” in the present specification) is conceptually arranged in the drawing.
[0024]
The jet nozzle 10 and the axial liquid introduction hole 11 form a first nozzle 3 as a cavitation generating nozzle. In addition, the second nozzle 6 is provided at two positions corresponding to the vortex of the jet 5 on the wide side wall 4 in a direction perpendicular to the mounting surface of the first nozzle 3 (see FIG. 2). The jet 5 is a vortex, and usually has a single vortex central core 5a.
[0025]
The vortex core 5a is in a void state, is it moved away from the center line of the liquid to be ejected (which is also the center line in the longitudinal direction of the internal space V) CL, and does it constantly move and oscillate in the internal space V? The position is changed like this. Two second nozzles 6 are fixedly arranged at two positions where the probability of generating the vortex is the highest, and the fluid is supplied from the fluid supply device 8 toward the vortex central core 5a of the vortex.
[0026]
The fluid is a gas such as air, oxygen or ozone, but depending on the application, it may be a liquid such as liquid fertilizer or agricultural chemical, and it is a mixture of mist-like gas mixed with chemicals and liquid. Also good. By supplying this fluid toward the vortex core 5a, the jet 5 is brought to the wall side and the Coanda effect is promoted. As the jet 5 flows along the wall, the jet 5 is further stirred and mixed, and the generated bubbles are sheared. The jet 5 is further miniaturized by synergistic destruction of the ultrasonic wave due to cavitation and the like and the Coanda effect, and a sterilizing effect of bacteria in the liquid also occurs.
[0027]
Next, structural features will be described. The internal space V is partially opened at the inlet corresponding to the first nozzle 3, the inlet of the second nozzle 6, and the discharge port 9, but the internal space V into which the high-pressure fluid is introduced is substantially Can be treated as a closed space. That is, the six-faced walls forming the rectangular parallelepiped internal space V define the boundary of the liquid. The cavitation generation condition can be expressed as L / D2 ≧ 5, particularly when the liquid is water, as is generally known.
[0028]
L is the axial length of the jet hole 10. This relationship is not significantly affected by the viscous resistance of the liquid. Such a relationship is a relationship (reverse relationship) that has been studied to suppress the occurrence of cavitation. In order to positively generate cavitation, preferably L / D2 ≧ 8. Furthermore, the cavitation generation condition must satisfy the following relationship.
[0029]
D1 / D2 ≧ 2. This relationship is also a relationship (reverse relationship) that has been studied to suppress the occurrence of cavitation. In order to positively generate cavitation, preferably 4 ≧ D1 / D2 ≧ 3. Qualitatively speaking, the condition of cavitation generation is that the confined high-pressure fluid flows suddenly from a narrow space to a wide space. That is, it refers to a phenomenon in which an empty portion without water is generated in the water flow.
[0030]
In general, in a hydraulic machine or the like, cavitation must be avoided because it causes vibration, corrosion of the material, and damage. However, in the liquid purification apparatus 1 of the present embodiment, this phenomenon is actively used for sterilization of water and the like. Is. Where Bernoulli's theorem holds, cavitation does not occur. Further, cavitation flow is generated in a wide area when the fluid is swirled like a typhoon.
[0031]
Innumerable bubbles (cavitation) created in the vicinity of the vortex core 5a of the jet exiting the outlet of the jet hole 10 will eventually disappear. If eddy currents are generated, bubbles will continue to be born. Vortex shear forces the bubbles into seeds for other bubbles. That is, the bubbles generated from the jet holes 10 become seeds to reproduce the bubbles in the vortex. The condition for generating the vortex is that the size of the space constituting the jet flow generating portion is D1 <H and W / H> 4.
[0032]
That is, if the height H is large, the vortex does not last once it is generated but is immediately destroyed and disappears. This is because a vortex having an angular momentum is not stable in a three-dimensional space but stable in a plane. As will be described later, the center region of such a vortex circulates in a plane perpendicular to the height direction so that the entire inner space V substantially follows the four-surface wall except the upper and lower two-surface walls. That is, the entire liquid in the internal space V has an angular momentum with a slower speed than the rotational speed of the vortex core 5 a while a part of the liquid is discharged from the discharge port 9.
[0033]
It is effective if the internal space V configured to generate a jet with a vortex is generally flat. The liquid-only jet hole 10 may be replaced with a double nozzle that also introduces gas, and air bubbles may be mixed into the cavitation flow. In the situation where cavitation occurs, the pressure gradient in the area surrounding the bubbles becomes very large spatially, and the substance dissolved in the liquid near the cavitation bubbles is decomposed / separated, mixed / emulsified / stirred, Separation, conversely, dissolution of gas such as oxygen can be promoted.
[0034]
In the present embodiment, a fluid such as air is supplied to the vortex central core 5 a of the jet 5. By this supply, the vortex is further vortexed and many fine bubbles can be generated. As shown in FIG. 1, the vortex has a central portion, and the vortex is generated near one of the vortexes, and is rotated in the direction of the arrow along the wide wall surface. Although the vortex core 5a of the vortex flows, the fluid is ejected toward the vortex core 5a at the most effective position.
[0035]
In the present embodiment, the second nozzle is provided at two locations, but the present invention is not limited to two locations. One may be sufficient and two or more may be sufficient. Along with this ejection, the center of the vortex is guided to the wall surface side, air is sucked into the Coanda effect vortex center region, and vortex generation is further promoted. This allows sterilization and destruction of plankton by the impact force of the generated cavitation, and furthermore, a lot of fine bubbles are generated by the shear force by stirring and mixing by the Coanda effect and combined with the impact force of the cavitation. it can.
[0036]
5 and 6 show modifications in which the shape of the first nozzle is changed. FIG. 6 is a side view of FIG. Since the liquid supply device 7 and the fluid supply device 8 are the same as those of the embodiment shown in FIGS. 1 and 2, they are omitted. In the case of this example, it is tapered from the axial liquid introduction hole 11 to the ejection hole 10. In this case as well, as shown in FIGS. 1 and 2, generating the cavitation shows the same function, and the same effect can be obtained.
[0037]
FIG. 7 is a schematic cross-sectional view showing the dimensional relationship of the internal space of FIGS. 5 and 6 as in FIG. 8 and 9 show an example applied to a type that suppresses cavitation, and FIG. 9 is a side view of FIG. The first nozzle 3 is not stepped or tapered. Only the axial liquid introduction hole 11 constitutes a fluid supply nozzle. The jet injected through the first nozzle 3 is inferior in sterilizing effect, but is effective in increasing the amount of dissolved oxygen in the liquid. Rather, it can be applied to limited uses that avoid bactericidal action.
[0038]
The above-mentioned Coanda effect refers to a phenomenon in which fluid is attracted to a wall, and in a jet, a water jet is attracted to a wall of the internal space V to generate a vortex. Further, the jet is accompanied by an oscillation phenomenon in which the vortex is alternately swung left and right. This Coanda effect will be further described with reference to FIG. The jet flow generation box 20 shown in the figure is a flat, rectangular parallelepiped, and may basically be considered to have the same configuration as in FIG. In the embodiment shown in FIG. 10, they are arranged so that the longitudinal direction is vertical. An injection nozzle 21 that supplies pressurized seawater or the like from the pump unit 26 and injects it downward is fixed to the upper surface of the jet generation box 20.
[0039]
The injection nozzle 21 is an annular space having a cylindrical cross section. A partitioned jet generation chamber 22 is formed inside the jet generation box 20. The internal space V of the jet generation chamber 22 is a flat three-dimensional box-like space, the height of the space is represented by H, the width of the space is represented by W, and the length in the vertical (vertical) direction. Is L1, and the effective diameter of the opening of the injection nozzle 21 is D1, as described above, the eddy current generation conditions are D1 <H, W / H> 4, and H <L1. However, in addition to the above relationship, a relationship of W <L1 is preferable. The main jet 23 ejected from the ejection nozzle 21 is ejected in the direction of the approximate center line of the internal space V in the vertical direction.
[0040]
When the main jet 23 is jetted, the adhering vortex 24 which is a low-pressure vortex is generated at the eight corners of the jet generating chamber 22 due to the Coanda effect, and the adhering jet is generated in the main jet 23. In the jet generating chamber 22, the main jet 23 as shown in FIG. 10 flows in one of two directions, but this flow is unstable, so it switches to the other flow. That is, the main jet 23 is unstable, and a flow is generated while swaying in a plane parallel to the paper surface shown in FIG.
[0041]
These jets are a uniform mixture of liquid and gas, or liquid such as seawater and gas (oxygen, air, etc.), seawater and chemicals, water and gas, water and liquid (liquid fertilizer, agricultural chemicals, etc.) -Has functions of stirring, emulsification, liquid modification, liquid purification, etc. The jet including fine bubbles (mostly disappeared) in the internal space V is returned to the seawater or the like through the discharge port 27.
[0042]
The Coanda effect is effective even if it is not the dimensional condition described above. However, if the shape condition is preferably set as described above, a jet with a vortex flow is generated in the internal space as shown in the figure and effective. This jet flows in one direction and is swung alternately. In FIG. 10, an air suction pipe 25 is disposed at the center of the injection nozzle 21, and this is for drawing air from the atmosphere by negative pressure such as seawater injected from the injection nozzle 21. This corresponds to the above-described double nozzle and has the above-described effects.
[0043]
Although not shown in FIG. 10, by providing the second nozzle 6 on the side wall in the state of this figure, the same configuration as that of the above-described embodiment is provided. The flow of the jet 5 is sucked to the wall side by the supplied air or the like, and an attached vortex is generated. The internal space V is a complex vortex flow in which the cavitation phenomenon and the Coanda effect are mixed.
[0044]
[Operation of this embodiment]
As described in detail above, by generating a jet flow accompanied by a vortex in the internal space V and the jet generation chamber 22, ammonia, carbon dioxide, chlorine, oxygen, etc. in the seawater are degassed as described above. Furthermore, it destroys, sterilizes and kills fish parasite eggs, larvae, Escherichia coli, etc. in seawater and fresh water.
[0045]
In particular, the one provided with the first nozzle 3 capable of generating cavitation is capable of completely destroying the eggs of the parasite, which has been difficult to destroy in the past, to enhance the bactericidal effect, and also when purifying seawater and fresh water. The bubbles can be made finer, and the dissolved oxygen concentration can be increased, and its function is greatly improved compared to the conventional one.
[0046]
Although the present embodiment has been described by purifying seawater and fresh water, specifically, the purification of cultured water on land or sea, purification of freshwater farms, dissolution in ponds, dams, lakes, etc. It can be applied to increase the amount of oxygen, parasites in these places, inactivation of parasite eggs, removal of sea cucumbers, red tides, E. coli, etc., and sterilization. Furthermore, it can be applied to emulsification of water and oil, removal of volatile organic substances in the air by blowing air into the contaminated water, and the like.
[0047]
FIG. 11 shows a system example to which the present invention is applied, and is a seawater purification system. A kite 30 is floated on seawater or the like, and equipment such as a jet generation box 2 of the liquid purification device 1 of the present invention and a related pump unit 31, an oxygen concentrator 32, and a generator 33 is mounted on the kite 30. Sea water is pumped up from the suction port 34 in the drawing, sea water is supplied to the first nozzle of the jet generating box 2 through the pump unit 31, and oxygen is supplied from the oxygen concentrator 32 to the second nozzle to perform the above-described processing process. In this system, the seawater is purified and then discharged again from the discharge port 35 as treated water to a location different from the pumping position. For example, a system that destroys plankton in seawater and simultaneously dissolves oxygen.
[0048]
[Other embodiments]
As described above in detail, the present invention can be applied to various types of systems. Therefore, it goes without saying that the present invention is not limited to the description of the examples. For example, the fluid supply pipe 6 supplies fluid (air, oxygen, liquid, etc.) pressurized by a pump, but since the fluid supply pipe 6 is negative pressure, it is connected to a pump device that pressurizes the fluid. Alternatively, the fluid supply pipe 6 may be simply arranged so that air, oxygen, etc. are self-primed.
[0049]
Further, although the fluid supply pipe 6 is configured to eject the fluid in a direction perpendicular to the flow direction of the main jet, it may be supplied while being inclined and fixed. Further, as uses other than those described above, it can be used for emulsification of water and oil, and stirring and mixing of foods.
[0050]
【The invention's effect】

Thus, it also functions as a mixing and stirring device for enhancing the sterilizing effect and increasing the concentration of a gas such as oxygen or a foreign liquid in the liquid. In addition, the present invention has a very low cost liquid quality reforming apparatus having a simple internal space, generating cavitation and having the Coanda effect.
