Description

[0001] ULTRAFINE BUBBLE GENERATOR [0002]

More particularly, the present invention relates to a micro-centrifugal blowing apparatus, and more particularly, to a micro-centrifugal blowing apparatus which is capable of reducing the particle diameter of the bubbles to 1 μm or less, increasing the reaction area, The present invention relates to an advantageous ultra-fine embossing device.

Conventional micro-bubble generation method is a method in which air is compressed by an air compressor to saturate with water, and then pressure is lowered under atmospheric pressure to generate micro-bubbles, and air is bubbled through nozzles having fine holes An air bubble generating system is widely used.

For example, Korean Patent Registration No. 0902189 discloses a cylindrical body having an inlet and an outlet on both sides; A vortex forming unit disposed on an inlet side of the cylindrical body and vortex-forming a fluid including air bubbles passing through the cylindrical body; And a bubble generator disposed on the discharge port side inside the cylindrical body for forming air bubbles contained in the fluid that has passed through the vortex forming portion in a super strong air bubble generating portion, A fixing rod detachably coupled to the exhaust port while being opened; A support rod having one end coupled to the fixed bar and disposed along the axial direction of the body; And an air crushing unit coupled to an outer periphery of the support rod to crush air bubbles passing through the body.

However, even in the case of the above-described techniques, it is difficult to uniformly reduce the size of the bubbles to a size smaller than the micro size, so that it is difficult to expect sufficient residence time of the bubbles in the case of the microbubbles by such a device.

In addition, since the sufficient residence time of the bubbles in water can not be expected, there is a problem that energy must be excessively used for continuous bubble supply.

Hereinafter, the respective configurations will be described.

2, the gas-liquid mixing unit 2 includes a body 21 in which a first line 11 is formed at one side and a second line 12 is formed at the other side, A micro-pores 22 are formed in the body 21 so as to form a channel 23 and a periphery in the body 21 to form micro-pores, An air inflow pipe 24 which is exposed to the outside through the body 21 in the microcaring member 22 and an air inlet pipe 24 communicating with the air inflow pipe 24 inside the microcaring member 22, And a discharge pipe (25) formed with a plurality of discharge holes (251) for discharging the air introduced from the air inlet pipe (24) to the microcaring member (22).

The body 21 has a cylindrical tube shape in FIG. 2, but the present invention is not limited thereto. The fluid w1 flows into the first line 11 of the body 21 and the mixed fluid w2 or the fine air a2 and the fluid w1 To discharge the mixed fluid.

The microcaring member 22 is formed inside the body 21 so that the microcantilever 22 is formed with a periphery and a gap in the body 21 to form a channel 23 And fine pores are formed in the air passage 23, thereby finely discharging air into the flow passage 23.

The microcaring member 22 may be made of various materials, but it is preferable to use a ceramic member having micropores formed therein.

The air inlet pipe 24 is formed to penetrate the body 21 and to be exposed to the outside from the inside of the microcaring member 22. The air flow a1 flows into the microcaring member 22 while a negative pressure is formed in the flow channel 23 during the flow of the fluid w1 through the flow channel 23, 24 to introduce the outside air a1.

The discharge pipe 25 communicates with the air inflow pipe 24 inside the microcaring member 22 and is formed with a plurality of discharge holes 251 so that the air a1 flowing from the air inflow pipe 24, The air a1 discharged through the discharge pipe 25 passes through the micropores of the micropores 22 and becomes fine air a2 so that the air 23). The discharged fine air a2 is mixed with the fluid w1 and discharged through the second line 12 to the mixed fluid w2.

As described above, in the present invention, the air injected from the outside through the gas-liquid mixing process is converted into fine air (a2) by the gas-liquid mixing unit 2 to increase the generation efficiency of the ultra-high-strength catcher without a load at the rear end.

The ultra-fine strength foaming part 3 has a third line 13 communicating with the second line 12 to allow the mixed fluid w2 to flow in one side thereof and a third line 13 through which the super strength catcher w3 is discharged at the other side. And a hollow tube (32) having one end in communication with the second line (12) and the other end communicating with the third line (13) in the second body (31) .

The second body 31 is not limited in its shape and is configured to communicate with the second line 12 so that the mixed fluid w2 flows in one side the third line 13 is formed so that the wirings w1 and w3 are discharged.

The hollow fiber tube 32 is constituted as means for generating a super strength catcher.

As shown in FIG. 3, the hollow fiber tube 32 has a structure in which a plurality of hollow fiber membranes are formed to form a bundle. Each of the hollow fiber membranes forms a hollow to allow fluid to flow in the hollow, So that the hollow fiber membrane can flow to the outside through pores. The hollow fiber membrane is a known technology and its detailed description is omitted.

Particularly, the hollow tube 32 is arranged in a wavy form in which the crests and valleys are formed in the second body 31, so that a shearing force acts on the mixed fluid flowing through the hollow tube 32.

That is, the mixed fluid w2 flowing through the second line 12 flows through the hollow tube 32 and is arranged in the form of a wave of the hollow tube 32, so that a shearing force acts inside the hollow tube 32 (W3-1), and at the same time, even if the fluid is discharged to the outside through the fine pores formed in the hollow tube 32, the super fine force catcher (w3-2) is generated So that the ultra-fine strength yarn producing unit 3 generates two super fine yarn catchers by two lines.

The third line (13) is connected to the front end number line (13-1) through which the ultra-high strength catcher (w3-1) is discharged by the shear force in communication with the hollow fiber pipe (32) And the pore water line 13-2 through which the ultra-high strength catcher w3-2 is discharged is connected.

As a result, the ultra-high strength yarn forming unit 3 doubles the generation efficiency of the super strength yarn w3 as the super fine yarn width w3 is generated by the two lines as described above.

As described above, the ultra-high strength catcher (w3) generated by the ultra-high strength foaming part (3) is formed by the super fine catcher (w3-1) by the shear force of the hollow tube (32) In this ultra-high-strength catcher (w3), micro-bubbles having a particle size of more than a micro size and having a relatively small surface area and having a low mass transfer efficiency and a large floating velocity may be mixed. And only the pure ultra-high strength catcher w4 is discharged is shown as the excess gas recovery unit 4. [

The excess gas recovery unit 4 includes a fourth line 14 communicating with the third line 13 so as to allow a super strength catcher w3 to flow into one side thereof and discharging an excess gas a3 to the other side thereof, A third body 41 in which a fifth line 15 for discharging the ultra-high-strength catcher w4 is formed, and a third body 41 in which one or more flow paths 43 are alternately formed in the third body 41 And a partition wall (42).

The ultra-high strength catcher w3 flowing into the third body 41 through the third line 13 flows upward and downward through the partition wall 42 via the flow path 43, The large bubbles having a micro size or more, that is, the surplus gas a3 is floated and discharged to the outside through the fourth line 14, so that fine bubbles having a large particle size are filtered out from the ultra fine force catcher w3, 5 line < RTI ID = 0.0 > (l5). ≪ / RTI >

In this way, only the ultra-high-strength catcher (w4) is discharged, thereby increasing the surface area of the reaction and increasing the retention time in the water to increase the mass transfer efficiency.

The jetting unit 5 is configured to receive pure ultrahigh-intensity catcher w4 from the surplus gas collecting unit 4 and to jet the ultrapure water catcher w4 into the object water. In the present invention, An inner pipe 51 communicating with the fifth line 15 so as to allow the gravity catcher w4 to flow therein and having a plurality of inner injection holes 511 formed therein and an inner pipe 51 having a larger diameter than the inner pipe 51, And an outer tube 52 having an outer injection hole 521 formed at a non-opposed position.

The pure ultrahigh strength catcher w4 introduced into the inner tube 51 is injected into the outer tube 52 through the inner tube discharge hole 511 so that the inner tube 51 and the outer tube 52 are constructed as a double tube structure The superficial catch 521 is formed at a position not opposed to the inner tube spray hole 511 so that the super strength catcher w4 injected into the outer shell 52 collides with the outer periphery of the outer shell 52, 521, respectively. By such an action, the particle diameter and the injection speed of the fine bubbles contained in the ultra-high strength catcher (w4) are made more uniform and finer to be sprayed into water.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
