As shown in (b), water is jetted tangentially from the inner periphery of the tank 2, and the jetted water generates a vortex in the water in the tank 2. The injected water is pressurized by the pump 1 to 2 to 5 kgf / cm 2 .

向に噴出する水により渦流となる。In the above arrangement, first, water pumped by the pump 1 is supplied to the tank 2, and oxygen pressurized together with air by the compressor 3 is supplied into the tank 2 to dissolve the oxygen in the water in a pressurized state. At this time, in the present invention, the vicinity of the tip of the pipe 1a is branched in two directions, and the water passing through the control valve 5b falls from the space S of the tank. The water passing through the control valve 5a is arranged at a position where it is tangentially jetted from the inner periphery of the tank 2 as shown in FIG. 1 (b). When the water level in the tank 2 rises and reaches a predetermined level L, the water in the tank is swirled by the water jetted in the tangential direction.

態で水に溶存した酸素は水中で微細気泡となる。On the other hand, since the space S of the tank is filled with compressed air and oxygen from the compressor 3 and the oxygen cylinder 4, the air and oxygen are dissolved in the water in the tank 2 in a compressed state. Then, the water in the tank 2 is discharged into the lake P by opening the regulating valve 5c attached below the tank 2. As a result, oxygen dissolved in water under the above-mentioned pressurized state becomes fine bubbles in water.

ることができる。As shown in FIG. 1, when water is dropped into the tank, a nozzle is formed at the end of the pipe 1a, and if the water is dropped in a shower shape, the amount of dissolved oxygen can be increased. By adjusting the valve opening of the control valves 5a and 5b, the strength of the vortex and the amount of water falling can be adjusted.

われる。The microbubbles of oxygen (air) thus generated are very small, having a diameter of 5 to 10 μm, and float in water for a long time after generation. Then, secondary oxygen transfer occurs due to the long-time floating of the fine bubbles, and high-efficiency oxygen dissolution is performed again in the process.

とができる。Further, in the apparatus of the above-described embodiment, water is ejected from the pipe 1a located below the level L from the tangential direction of the tank inner periphery, and vortex flows in the tank 2 while entraining oxygen in the upper part of the tank 2. Therefore, the effect of introducing and diffusing oxygen into water in the tank can be enhanced. Further, since the pressure in the tank is relatively low and is about 2 to 3 kgf / cm 2 , the efficiency of dissolving oxygen in lake water can be greatly improved without a sudden rise of fine bubbles when released into water. .
