Hereinafter, a microbubble generating device using a dissolution tank capable of dissolving air at a high concentration according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

Microbubble generating device using a dissolution tank according to the first embodiment of the present invention is connected to the feed pump 110, the dissolution tank 120, the dissolution tank 120 has a path through which the water flowing out of the dissolution tank can move It may include a common conduit 150, and a plurality of bubble generating nozzles (140-1 to 140-14). Meanwhile, for the purpose of explanation, FIG. 1 additionally shows a flow meter 120.

The microbubble generating device using the dissolution tank according to the present embodiment can be placed in the water in the tubular body, as shown in Figure 1, to generate micro and / or nanobubbles in large quantities.

In the microbubble generating device having the dissolution tank according to the present embodiment, water is introduced into the dissolution tank 120 by the pump 110, and the water introduced into the dissolution tank 120 is sprayed in contact with air to form a spray. Then, it is dropped and a high concentration of dissolved water (hereinafter referred to as "dissolved water") is accommodated in the dissolution tank 120. Solid solution seawater in the dissolution tank 120 is sprayed through a plurality of bubble generating nozzles (140-1 to 140-14), it is possible to generate micro bubbles.

As described above, it is assumed in the present specification that air is mixed with water, but this is merely illustrative, and includes any gas that needs to make microbubbles such as ozone or pure oxygen, but not air. On the other hand, the plurality of bubble generating nozzles (140-1 to 140-14), although using the one disclosed in Figure 3, it will be possible to use other suitable types of nozzle unit.

The pump 110 may supply the incoming water to the dissolution tank 120 at a predetermined pressure. As will be described later, according to the present invention has a structure that can generate a large amount of micro bubbles at the same time while the pressure applied to the water supply pump 110 is minimized.

On the other hand, in order to remove impurities of the water flowing into the pump 110, the porous mesh member M as shown in Figure 1 may be installed on the inlet side of the pump 110. Therefore, the water flowing through the pump 110 is introduced into the water containing no possible impurities.

The dissolution tank 120 receives water discharged from the pump 110 and sprays the sprayed water in contact with air to generate solid solution seawater in which air is dissolved in water.

1 and 2, the dissolution tank 120 according to the present embodiment is the tank body 121, the spray nozzle 123, the air compressor 125, the controller 126, the first and second water level sensors 127a and 127b and vent 128.

Water introduced into the tank body 121 is sprayed and sprayed through the spray nozzle 123, and the solid-solution seawater is generated while falling in contact with the air supplied from the air compressor 125 to the tank body 121, the tank body ( 121). This method of atomizing water and contacting with air is preferable to generate solid solution seawater compared to the conventional dissolution method.

In addition, the dissolution tank 120 according to the present embodiment will be described later, the first for detecting the first water level (h1) and the second water level (h2) so that the water level of the dissolved seawater accommodated in the tank body 121 is kept high The first and second water level sensors 127a and 127b are installed, and the controller 126 detects the level of the solid-solution water contained in the tank body 121 from the first level sensor 127a or the second level sensor 127b. When the air compressor 125 and the melting tank 121 may be configured to control the opening and closing of the valve (V1) installed on the flow path.

The tank body 121 is formed in a cylindrical shape. It may be made of a metallic material, but need not necessarily be a plastic injection molding of a transparent or translucent material, and may be made of various other materials.

Meanwhile, the dissolution tank 120 may include an inlet 124 for receiving air, an inlet 122 for receiving water from the pump 110, and an outlet 129 for discharging the melted water toward the bubble generating nozzle. have.

The spray nozzle 123 sprays the water introduced into the tank body 121 from the pump 110 into a spray state and sprays it into the upper side of the tank body 121. The spray nozzle 123 is a general known technique, and various types of structures may be applied to make water into a spray form.

The air compressor 125 is a means for supplying air into the tank body 121. The valve V1 is provided on the flow path connecting the air compressor 125 and the tank body 121. In this case, the valve V1 is an electronic valve and electrically connected to the controller 126 to open a flow of air supplied from the air compressor 125 to the tank body 121 by a control signal of the controller 126. Block it.

The first water level sensor 127a and the second water level sensor 127b are means for sensing the height (water level) of the solid-solution water contained in the tank body 121 and are electrically connected to the crawler 126. In this embodiment, although an ultrasonic sensor is used, various types of sensors for detecting an optical sensor and a water level may be used.

The first level sensor 127a detects that the height of the dissolved water in the tank body 121 is h1, and the second level sensor 127b detects that the height of the dissolved water in the tank body 121 is h2 lower than h1. Installed to detect. In this embodiment, the height h1 may be substantially the same as the position of the bottom of the spray nozzle 123.

When the first water level sensor 127a detects that the water level is at the height h1, the controller 126 according to the present embodiment opens the valve to supply air into the tank body 121. As a result, the air pressure in the tank body 121 is increased to press the solid solution seawater contained in the tank body 121, so that the height (water level) of the solid solution seawater is lower than the first water level h1.

In addition, when the second water level sensor 127b detects that the water level is at the height h2, the controller 126 shuts off the valve V1 to stop the supply of air into the tank body 121.

By the control of the controller 126 as described above, the level of the dissolved seawater contained in the tank main body 121 can be maintained between the first level h1 and the second level h2, and thus the tank main body 121. It is possible to improve the efficiency of the production of solid solution seawater in the interior, and to secure sufficient quantity of solid solution seawater to supply a plurality of bubble generating nozzles 140-1 to 140-14.

That is, it is possible to prevent the solid solution seawater from accumulating to a higher level than the spray nozzle 123, so that the spray nozzle 123 is immersed in the solid solution seawater to prevent the water flowing into the tank body 121 from being mixed with the solid solution seawater without being atomized. have. In addition, it is possible to secure a minimum amount of dissolved seawater for supplying a plurality of bubble generating nozzles (140-1 to 140-14) by preventing the water level of the dissolved seawater to fall below the height h2.

On the other hand, the upper part of the tank body 121 is provided with a vent 128 for discharging the air to the outside to adjust the air pressure in the tank body 121. The vent 175 according to the present embodiment is electrically openable and electrically connected to the controller 126.

In this case, when the controller 126 detects that the water level is h2 by the second water level sensor 127b, the controller 126 opens the vent 128 to draw out the air in the tank body 121, thereby removing the air in the tank body 121. To quickly reduce air pressure.

This is to lower the high pressure in the tank body 121 quickly when the level of the dissolved water in the tank body 121 is lowered to h2 or lower, so that the level of the dissolved water rises above the h2. .

As described above, since the dissolution tank 120 according to the present embodiment has a structure in which the water flowing from the pump 110 is sprayed and sprayed and contacted with air, the generation rate of the solid solution seawater is improved.

In addition, the dissolution tank 120 controls the supply of air into the tank body 121 by the first and second water level sensors 127a and 127b and the controller 126 to maintain the level of the dissolved seawater at a constant level. In addition, it is possible to not only improve the generation efficiency of solid solution seawater, but also to secure sufficient solid solution seawater in the tank main body 121 to supply the plurality of bubble generating nozzles 140-1 to 140-14.

The flow meter 130 may measure the flow rate of the dissolved seawater flowing into the plurality of bubble generating nozzles 140-1 to 140-14 from the dissolution tank 120.

A plurality of bubble generating nozzles (140-1 to 140-14) is introduced into the solid solution seawater contained in the tank body 121, and discharged into the water at high speed to generate micro bubbles in the water by colliding the water and the solid solution seawater. .

Therefore, since the solid solution water discharged from the bubble generating nozzles 140-1 to 140-14 is discharged at a high speed while turning at high speed, the production rate of the micro bubbles is improved.

Since the plurality of bubble generating nozzles 140-1 to 140-14 performing the above functions have the same structure, only one bubble generating nozzle 140-1 will be described. 3 to 5, the bubble generating nozzle 140-1 includes a nozzle body 141 and a melt water rotation induction guide part 149 provided inside the nozzle body 141.

The nozzle body 141 is a part forming an appearance of the bubble generating nozzle 140-1. It may be made of a metallic material, but it is not necessarily required, and may be made of a plastic injection molding of transparent or translucent material and may be made of various other materials.

Therefore, since the solid solution water introduced through the nozzle inlet 143 is started immediately without receiving resistance from the molten water rotation guide unit 149, the rotation speed of the molten water may increase. As described above, the pressure applied to the pump 110 may be minimized.

The dissolved water rotation guide 149 includes a plurality of dissolved water guide walls 149a and 149b that allow water flow from the nozzle inlet 143 to the dissolved water outlet 145.

Dissolved water discharged from the dissolved water discharge portion 225 of the turning unit 220 and introduced into the separation chamber 230 continues to rotate, and the undissolved air is dissolved in the separation chamber 230 by the turning. It is separated by the number of turns and gathers near the central axis of the separation chamber 230.

Although not shown, undissolved air mixed in the dissolved water turning in the separation chamber 230 is separated and collected on the central axis of the separation chamber 230, and according to the experimental results, the current side of the separation chamber 230 is shown. From the side to the wake side, the area becomes narrower. It is estimated that part of the air which has not been separated is dissolved in the dissolved water again according to the moving direction of the dissolving water that turns.

The length L of the separation chamber 230 corresponds to the time at which the dissolving water is turning, and therefore, the separation chamber 230 is preferably made to have an optimized length so that the undissolved air can be sufficiently collected at the central axis. Do.

11 is a view for explaining the separation chamber and the swing unit of FIG.

Referring to FIG. 11, an example in which the separation chamber 230 and the swing unit 220 are coupled to each other is illustrated. As shown in FIG. 11, the separation chamber 230 and the turning unit 220 are coupled, and the turning unit 220 carries the melted water flowing out of the venturi injector 210 in the tangential direction of the turning unit 220. Inflow. The separation chamber 230 and the turning unit 220 may be fastened using a fastening means such as a screw, and the separation chamber 230, the opening P1 of the substrate 232, and the dissolved water of the turning unit 220 may be fastened. The discharge part 225 is interconnected so that the melted water flows. That is, the dissolved water discharged from the dissolved water discharge part 225 is introduced into one end of the tubular separation chamber 230 through the opening of the substrate 232. Thereafter, the dissolved water introduced into the separation chamber 230 flows out to the other end of the separation chamber 230, and the dissolved water thus moved is moved to the dissolution tank side.

As described above, the microbubble generating device having the dissolution tank according to the second embodiment of the present invention rotates water and air through the turning unit 230 to generate dissolved water, and then supplies the dissolution water to the dissolution tank 120. Therefore, since dissolved water is first formed in the turning unit 230 and then dissolved in the dissolution tank 120 again using the generated dissolved water, a higher concentration of solid solution seawater can be generated. It is possible to improve the microbubble production rate through the bubble generating nozzles (140-1 to 140-14).
