[0002] The dissolved air device is a device used to increase the amount of dissolved air in the liquid. It is widely used in the fields of air flotation, aerobic aeration, and ozone water production. Air pump and impeller dissolved air are realized in four ways; however, the pressure dissolved air tank of the existing air compressor-pressure tank dissolved air device has a large volume, and it is easy to block if the filled type dissolved air tank; the dissolved air pump Although the air-dissolving device has less equipment, the efficiency of dissolving air is low; the maintenance and repair costs of the mechanical equipment of the eddy current dissolving device are relatively high; the air-dissolving device of the impeller produces large bubbles, the utilization rate of the bubbles is low, and the air flotation effect is poor

[0003] The Chinese patent announcement number is CN201551967U two-stage vortex microporous air dissolving device, which adopts microporous cloth air tube to dissolve air, and the water flow enters from the top of the air dissolving device and is discharged from the bottom; this kind of air dissolving device has a simple structure, but there is a water flow process Shorter, larger bubbles, and lower efficiency of dissolved air

[0004] The Chinese patent announcement number is CN2652916Y, a kind of swirling air dissolving device, which adopts a microporous plate to dissolve air, and the water flow enters tangentially from one end and flows out tangentially from the other end; Short, large bubbles, low efficiency of dissolved air

[0005] The Chinese patent announcement number is CN201614307U. The swirl type high-efficiency gas dissolving tank adopts air-water mixing and powerful dissolving gas. The water flow tangentially enters from the lower part of the tank side and flows out from the upper part of the tank side. The second layer of baffles creates a swirling flow in the rising water flow; although this kind of air dissolving device has a simple structure, it has the problems of short water flow and low efficiency of dissolving air

[0006] The Chinese patent announcement number is CN101347687A, a kind of generating device with micro-bubble oil-containing water, which adopts microporous cloth trachea to dissolve air, and a plurality of microporous tubes can be placed in the columnar dissolved air water generator, and the water flow enters the device tangentially, with spiral flow The form passes through the microporous tube, followed by a large bubble remover to remove undissolved gas; this gas-dissolving device creates a swirl in the microporous tube, which strengthens the mass transfer of the gas to the water, but the flow of the water is relatively still Shorter, the water-air contact surface is smaller, and the gas-dissolving efficiency needs to be improved
