Some specific embodiments of the various embodiments of the present invention will be described with reference to the drawings, in which like reference numerals are used to describe specific embodiments of the invention.

In describing the specific embodiments below, various specific details are set forth in order to explain the invention more specifically and to help understand. However, one of ordinary skill in the art having enough knowledge to understand the present invention can recognize that it can be used without these various specific details. In some cases, it is mentioned in advance that parts of the invention which are commonly known in the description of the invention and which are not highly related to the invention are not described in order to prevent confusion in explaining the invention without cause.

In the present specification, the term "micro bubbles" is used in the concept including "micro bubbles" or "nano bubbles" or "micro bubbles and nano bubbles". Examples of fine bubbles include air fine bubbles, oxygen fine bubbles, and / or ozone gas fine bubbles.

FIG. 1 is a functional block diagram of a collision type micro bubble generator according to a first embodiment of the present invention, and FIG. 2 is a structural diagram of the impact type micro bubble generator shown in FIG. 1.

Referring to these drawings, the collision type microbubble generating device according to the present embodiment includes an injector 100, a collision type air generation unit 200, and a collision type nozzle part 300.

The injector 100 injects gas such as air, oxygen, and / or ozone gas (hereinafter, referred to as “gas”) to dissolve in water. That is, the injector 100 is a portion where water and gas are mixed. At this time, the gas not dissolved in the water is present in the form of a bubble (bubble).

Although the injector 100 is schematically illustrated in FIG. 2, the injector 100 may include a water inlet 100a through which water is introduced, a gas inlet 100b through which gas is injected, and water in which gas is mixed. Water and gas outlet 100c.

In this case, the width is gradually narrowed from the pump 50 to the inlet 100a through which water is introduced, and the gas inlet 100b is formed at the narrowest width. The water and gas outlets 100c are provided to gradually increase in width toward the collision type air generating unit 200.

Thus, the width of the water and the gas flows become narrower and wider, and since water and gas are combined therebetween, a part of the injected gas is included in the water in the form of a bubble, thereby forming a collision type airflow generating unit ( 200).

The colliding air generating unit 200 collides the water discharged from the injector 100 and the water discharged from the gas outlet 100c (partly the gas is mixed with water) and the gas, that is, the mixed water and the gas They collide to mix water and gas.

The collision type air generating unit 200 includes a vane 204 and a vane support 202.

The vane support 202 has a substantially rod-shaped block with an end closed, and the vane 204 is helically fixed to an outer surface of the vane support 202. At this time, the shape, width, and size of the vane 204 need to be limited to a specific shape because a structure that serves to collide violently with water and pressurizes the air is sufficient. none.

However, as in the present embodiment, when the vanes 204 are provided in a spiral shape, the area where water and gas passing through the area collide with the vanes 204 may be widened, thereby providing a more excellent effect of mixing the water and the gas. have.

Since the vane support 202 has a rod-shaped end portion, water mixed with the water discharged from the injector 100 and the gas discharged from the gas outlet 100c generates a collisional airflow with the outer surface of the vane support 202. Only the space S between the inner surface of the part 200, that is, the vane 204 is passed through. By passing through the vanes 204 continuously, water and gas collide violently with each other to create an airflow.

The impingement nozzle unit 300 is a part for generating a fine bubble by colliding the aerosol mixed with water and gas, that is, gas is mixed by the impingement air generation unit 200.

The impact nozzle unit 300 sequentially extends the first diffusion part 307, the first extension part 309, the collision member 311, the second diffusion part 313, and the second extension part in the direction in which the air flows. A portion 315 is included.

The first diffusion part 307 receives the airflow mixed with water and gas from the collision type airflow generation unit 200 and flows it out to the first extension part 309. The first diffusion part 307 includes an inflow end 303 for receiving an airflow and an outlet end 305 for outflowing the airflow.

The inlet end 303 is formed narrower than the outlet end 305. The diameter of the outlet end 305 is also formed to be narrower than the diameter of the collision type air generation unit 200. In addition, the structure of the region of the first diffusion part 307 in the collision type nozzle part 300 has a structure in which the diameter gradually increases from the inlet end 303 to the outlet end 305.

The first extension part 309 is formed larger than the diameter of the outlet end 305 (discontinuously large) but flows the airflow while maintaining the same diameter for a predetermined section. Since the collision member 311 is provided in the region of the first extension portion 309, the adhering body collides with the collision member 311 while passing toward the first extension portion 309 through the first diffusion portion 307.

In other words, the air flowing through the first diffusion part 307 is subjected to a lot of pressure because the flow path of the first diffusion part 307 is narrow. In this state, the first extension part having a larger diameter, that is, a wider width, is provided. When 309 is reached, since the pressure suddenly weakens and collides with the collision member 311, fine bubbles may be generated.

As described above, the collision member 311 is disposed in the region of the first extension portion 309 and serves to generate fine bubbles as the air collides with each other. In this embodiment, the collision member 311 is provided with a plate-like body having a large surface area, and is fixed to the inner wall surface of the collision-type nozzle unit 300 by the trivet leg 311a. Such a collision member 311 is not necessary to be limited in shape because it is sufficient if the structure that the air can collide.

In the present invention, the air flowing through the first diffusion portion 307 is in a state of receiving a lot of pressure, the pressure received while reaching the first extension portion 309 is suddenly weakened so as to collide with the collision member 311 at the same time It is preferable.

Water containing the fine bubbles generated by hitting the collision member 311 is discharged through the second diffusion portion 313 and the second extension portion 315. According to one embodiment of the present invention, it is advantageous in that more fine bubbles can be made when the second diffusion part 313 and the second extension part 315 are provided.

The second diffusion part 313 is provided in the same manner as the structure of the first diffusion part 307. That is, the diameter of the first bubble 309 gradually increases from the diameter of the first extension portion 309 to the rearward direction with respect to the direction in which the water containing the fine bubbles flows.

The second extension part 315 is connected to the second diffusion part 313 so that the predetermined length section maintains the largest diameter of the second diffusion part 313.

Referring to the process of making the water containing the fine bubbles by the collision-type micro bubble generating device having such a configuration as follows.

First, when water enters the injector 100 through the pump 50 and other paths, the water and the gas are mixed with each other in the course of passing through the injector 100 so that the gas dissolves in the water. As described above, the gas that is not dissolved in the water is present in the form of a bubble is directed to the collision type air generating unit 200.

Water and gas passing through the injector 100 are directed to the collision type air generation unit 200, and the water discharged from the water and gas outlet 100c of the injector 100 is performed by the impact type air generation unit 200. Some are gas-mixed water) and the gas is collided, that is, the mixed water and gas collide with each other, mixing water and gas first.

Next, the water and gas discharged from the water and gas outlet (100c) of the injector 100 is the space (S) between the outer surface of the vane support 202 and the inner surface of the collision type air generating unit 200, that is, the vanes Only pass into the space in which 204 is located. As it passes through, it continuously hits the vane 204, and water and gas collide violently with each other to generate an airflow.

The air generated by the colliding air generating unit 200 passes through the colliding nozzle unit 300. First, the air flowing through the first diffusing unit 307 is formed of the first diffusing unit 307. FIG. Since the flow path is narrow, a lot of pressure is applied, and in this state, fine bubbles are generated as they reach the first extension portion 309 having a large diameter, that is, the width thereof, and collide with the collision member 311. The water in which the fine bubbles are formed in this manner is formed into many fine bubbles passing through the second diffusion portion 313 and the second extension portion 315.

As such, according to the present embodiment, since the manufacturing cost is low due to the simple and simple structure, more fine bubbles are produced per unit time or per unit capacity of the pump 50 for pumping water into the injector 100. I can make it.

FIG. 3 is a perspective view illustrating the inside of a collision type air bubble generating unit partially removed from the collision type micro bubble generating device according to a second embodiment of the present invention, and FIG. 4 illustrates a collision according to a third embodiment of the present invention. It is a perspective view of the vane in a type | mold micro bubble generator.

Referring to FIG. 3, in the second embodiment, the collision type air generating unit 200a includes a vane 203 and a cover 205 surrounding the vane 203.

The vanes 203, like the vanes 204 (see FIG. 2) of the first embodiment described above, cause the water and the gas to collide violently with each other and mix with each other, and at the same time, pressurizes the air body.

The vane 203 of the second embodiment has a shape in which the partial portions are arranged long in a pretzel shape. As described above, the shape, width, size, etc. of the vane 203 may have the same shape as in the present embodiment because it is sufficient if the structure in which water and gas collide violently with each other is sufficient.

Since the vanes 203 occupy a certain amount of space in the collision type air generating unit 200a, as the flow velocity increases, water and gas collide with each other, separate, and recombine again.

On the other hand, as will be described repeatedly, the configuration of the collision type air generating unit 200a need not be limited to the diagram of FIG. That is, even if it is changed to the structure of the collision type air generating unit 200b having the vanes 203a as if the vanes are arranged in a line as shown in FIG. 4, there is no problem in providing the effects of the present invention.

Therefore, if the structure of the vanes (not shown) to smoothly occur the process of collision and separation and coalescing of the two airflow and increase the pressure received by the airflow to increase the flow rate, the shape and structure of Figures 2, 3 and 4 It can be applied away.

5 is a structural diagram of a collision-type microbubble generating device according to a fourth embodiment of the present invention.

Referring to this figure, most of the configuration of the collision-type microbubble generating device according to the fourth embodiment is the same as that of Fig. 2 of the first embodiment. However, the structure of the collision nozzle part 300a, especially the collision member 411 of the collision nozzle part 300a, differs from FIG. 2 of 1st Embodiment.

The collision member 411 in FIG. 5 is shown schematically, but its form shows a view in which the airflow can have a larger portion, area, and repeatedly collide. For example, it may be considered that the pinwheel shape is arranged in a plurality, it can be more advantageous to make a fine bubble because the collision of the airflow can be further deepened.

Of course, since the scope of the present invention is not limited thereto, the shape of the collision members 311 and 411 in which the two bodies collide with each other does not need to be limited to FIGS. 2 and 5, and may be changed to other structures.

In FIG. 2, the collision member 311 is illustrated and described as being supported by the trivet leg 311a, but in FIG. 5, the support structure of the collision member 411 is omitted for convenience of description.

However, in the case of FIG. 5, the structure for supporting the collision member 411 with a material of appropriate rigidity and oxidation resistance, that is, the collision member 411 is provided on the side surface of the first extension portion 309 or the second diffusion. Implementing a configuration to be fixed to the side of the unit 313 is possible to those skilled in the art without excessive trial and error. Therefore, the supporting structure for supporting the collision member 411 will not be described in detail.

6 is a structural diagram of a collision-type microbubble generating device according to a fifth embodiment of the present invention.

Referring to this figure, most of the configuration of the collision-type microbubble generating device according to the fifth embodiment is also the same as that of Fig. 2 of the first embodiment. However, the internal structure of the collision nozzle part 300b, especially the collision nozzle part 300b, is slightly different from FIG. 2 of 1st Embodiment.

In this regard, the inclined nozzle portion 300b of the fifth embodiment is further provided with an inclined portion 308 connecting the first diffusion portion 307 and the first extension portion 309.

The inclined portion 308 is gradually connected to the first extension portion 309 while its diameter is gradually increased at the outlet end 305 of the first diffusion portion 307. Even if such a structure is applied, there is no problem in generating microbubbles due to the collision of airflow.

7 is a functional block diagram of a collision-type microbubble generating device according to a sixth embodiment of the present invention.

Referring to FIG. 7, the collision type micro bubble generating apparatus of the sixth embodiment includes an injector 100, a collision type air generation unit 200, and a plurality of impact type nozzle units 300.

Since the functions of the pump 50, the injector 100, the collision type air generating unit 200, and the impact type nozzle unit 300 shown in FIG. 7 are the same as those described with reference to FIGS. 1 and 2, It will not be described again.

However, since the collision type air generation unit 200 illustrated in FIG. 7 is connected to the plurality of collision type nozzle units 300 simultaneously and / or sequentially, a larger amount of fine bubbles may be generated than the above-described embodiments. It is possible to produce water containing.

8 is a table showing experimental results generated by the collision-type microbubble generating device according to an embodiment of the present invention. Referring to FIG. 8, it can be seen that the collision-type microbubble generating device according to an embodiment of the present invention can generate microbubbles of various sizes ranging from micro to nano units.

All of the above-described embodiments have a structure capable of sufficiently generating microbubbles of various sizes ranging from micro to nano units while receiving less pressure from the two aliphatic bodies. That is, components such as the injector 100, the colliding air generating unit 200, and the collapsing nozzle unit 300, in particular, the first diffuser 307 and the first extension of the colliding nozzle unit 300. The configuration in which the portion 309, the collision member 311, the second diffusion portion 313, and the second extension portion 315 are sequentially formed can sufficiently generate microbubbles while the air is relatively low in pressure. So that it is organically bound.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims.
