Description

Micro Bubble Generating Apparatus

The present invention relates to a microbubble generator, and more particularly, to a microbubble generator capable of generating microbubbles with a compact and efficient structure, which can be widely used where microbubbles are required.

Recently, the field of using water containing air, oxygen, and ozone gas as fine bubbles is increasing. For example, water containing fine ozone gas bubbles may be used for washing or purification of wastewater, and water using oxygen gas bubbles may be used for backwashing or purification of lakes.

In general, bubbles as air bubbles are generated by water pressure and shear force of air in water by a fine aeration device or other device, which is closely related to pressure, air volume, viscosity of water, and water temperature.

Bubbles by a general aeration device are generated in water with a bubble size of 50 μm or more in diameter. However, with this size, it is difficult to use water for washing or purifying wastewater.

Therefore, devices for generating separate microbubbles (that is, microbubbles or nanobubbles) have been developed and used in addition to the conventional aeration device, but the efficiency of generating microbubbles is still low.

Referring to these drawings, the microbubble generator according to this embodiment includes a mixing module 30 in which a water supply line 10 and an air supply line 20 are connected to mix water and air, and the mixing module ( 30 , and a mixing fluid line 40 through which a fluid formed by mixing water and air flows, and a microbubble generator 100 .

The microbubble generator 100 is connected to the mixing fluid line 40, and it forms and discharges microbubbles in water based on the mixing fluid flowing in the mixing fluid line 40, but disassembly and assembly for maintenance made possible.

Since the disassembled and assembled microbubble generator 100 has a disassembled and assembled structure, cleaning and maintenance are easy. In addition, since it works in conjunction with the mixing module 30, the amount of microbubbles generated is high.

In other words, the microbubble generating device according to the present embodiment can generate microbubbles with a compact and efficient structure, and thereby can be widely used where microbubbles are required.

The disassembled and assembled microbubble generator 100 includes a main tube body 111, a tube head portion 112 coupled with a flange P at one end of the main tube portion 111, and the tube head portion 112 ) at one end of the screw (S) coupled but having a coupling groove portion 113a to which the coupling protrusion of the mixing fluid line 40 catches and engages, and a line coupling pipe detachably coupled to the mixing fluid line 40 It includes a body 113 .

In addition, the disassembled and assembled microbubble generator 100 is coupled to the flange P at the other end of the main tube body 111 , but a plurality of microbubble water discharge holes through which microbubbles formed with microbubbles are discharged. It further includes a discharge tube body portion 114 having a (114a).

The disassembled and assembled microbubble generator 100 becomes the main body part 111, the pipe head part 112, the line coupling body part 113 and the discharge pipe body part 114, and these are disassembled at the corresponding positions. As it is an assembled structure, it can provide excellent effects in the assembly and maintenance of parts.

The disassembled and assembled microbubble generator 100 is disposed in the inlet area within the tubular head part 112, the mixing fluid collision member 121 on which the mixing fluid collides, and the mixing fluid collision member 121 is formed to be inclined. The outlet is formed to have a narrower width than the inlet, and further includes a plurality of inclined through-holes 122 through which the fluid formed by colliding with the mixing fluid collision member 121 passes to the rear end.

After the mixing fluid collides with the mixing fluid collision member 121 , it is advantageous in generating bubbles because it is discharged to the rear end through the inclined through-hole 122 .

The disassembled and assembled microbubble generator 100 is provided to be connected to the rear end of the mixing fluid collision member 121 in the tubular head part 112, and the fluid collided with the mixing fluid collision member 121 flows. The fluid flow space portion 125 further includes a fluid flow block 124 formed therein.

At this time, the fluid flow space portion 125 is inclined toward the rear end at the portion communicating with the inclined through portion 122 and becomes narrower in width, and forms a horizontal tube shape at the rear end. That is, since the bubbles split by colliding with the mixing fluid collision member 121 are transferred to the rear end in the form of moving from a wide space to a narrow space of the fluid flow space part 125 , it can also contribute to bubbling in this process.

The disassembled and assembled microbubble generator 100 forms a boundary region between the main tube body part 111 and the tube body head part 112, and finely injects the fluid flowing in from the rear end of the fluid flow space part 125. It may further include a fine mesh member 131 having a fine through hole 132 to pass therethrough.

After the bubbles collided with the mixing fluid collision member 121 and splitted are moved from the wide space of the fluid flow space part 125 to the narrow space, the microscopic hole 132 of the fine mesh member 131 passes through the form. Therefore, it is advantageous for the formation of microbubbles.

When it comes to this stage, a large number of microbubbles are contained in the water, but when the water moves to the rear end in a state in which the water collides with the collision unit 140 for forming bubbles again, there is an advantage in that the bubbles can be broken up into smaller pieces. Therefore, the more the contact area increasing protrusion 142, the more advantageous.

The disassembled and assembled microbubble generator 100 is disposed at the rear end of the bubble-forming collision unit 140 in the main tube body 111 and passes the fluid passing through the bubble-forming collision unit 140 in a narrow passage. A plurality of first narrow passage wall parts 151 transferred to the A second narrow passage wall portion 152 may be further included.

In addition, the disassembled and assembled microbubble generator 100 is disposed in the space between the first narrow passage wall part 151 and the second narrow passage wall part 152 and a plurality of balls to increase the amount of microbubbles generated A member 160 may be further included.

Pressurizing the water in contact with the ball members 160 while the bubble-formed water passes through the hole of the first narrow passage wall part 151 and the hole of the second narrow passage wall part 152 . Therefore, the amount of microbubbles generated may be increased. In addition, it is possible to prevent the ball member 160 of this part from being clogged.

In addition, the disassembled and assembled microbubble generator 100 of this embodiment is coupled to a hole formed by the second narrow passage wall part 151 but a fine hole mesh having a plurality of microholes 171 . By further including 170, it is possible to maximize the amount of microbubbles generated.
