Problems solved by technology

[0003] However, in the existing dissolved air system, the return water is pressurized by a high-pressure pump and directly enters the dissolved air tank. The mixed flow state of water and gas is poor, and it is difficult to ensure sufficient contact between gas and liquid. Therefore, the amount of dissolved air in the dissolved air water is low, and the Poor floating effect

Embodiment Construction

[0008] Such as figure 1 As shown, the present invention includes an air-dissolving tank 1. The main body of the dissolving air tank 1 is a vertical column structure. A water outlet 2 is provided on the lower side wall of one end of the dissolving air tank 1. The dissolving air tank located on the same side as the water outlet 2 1. A liquid level float switch 3 is provided on the upper end wall. An air inlet 4 is provided on the upper side wall of the other end of the dissolved air tank 1. A water inlet 5 is provided at the top of the dissolved air tank 1. A water inlet 5 is provided below the water inlet 5. There is a nozzle 6 with the opening facing down, and it is located in the gas dissolving tank 1, which can be directly sprayed to promote the gas-liquid contact. Quality and efficiency, the float 8 of the liquid level float switch 3 is located above the inner filler 7 of the dissolved gas tank 1, and the inner bottom of the dissolved gas tank 1 is provided with an ultrason...

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an ultrasonic dissolved air system. Background technique [0002] In the water treatment industry, air flotation equipment is usually used to separate oily or light suspended solids in water. The working principle of air flotation equipment is to dissolve air into the return water under high pressure in advance to form a supersaturated high-pressure air-water mixture, and then The air-water mixture is released into the water through the releaser under reduced pressure, generating a large number of tiny bubbles, which adhere to the oily or light suspended matter in the water, carry them to the water surface, and use the scum scraper to scrape the scum out of the air flotation equipment , so as to separate and remove oily or light suspended matter from sewage. [0003] However, in the existing dissolved air system, the return water is pressurized by a high-pressure pump and directly e...
