Abstract

The present invention relates to a new-type self-feeding gas-liquid two-phase nozzle with projected circular ring structure. It includes an internal cylinder, an external cylinder and an intermediate cylinder. The lower end of said internal cylinder is equipped with a reducing liquid-spraying nozzle, an air suction inlet is set on the external cylinder, the internal cylinder is cover-mounted and fixed in the intermediate cylinder, in the front position of liquid-spraying nozzle in the intermediate cylinder interior a projected circular ring body is set and between the liquid-spraying nozzle and projected circular ring body a circular ring gap is formed, on the intermediate cylinder the air distributing holes are arranged and the reduced neck of the projected circular ring body is equipped with air distributing holes which are communicated with and correspondent to the above-mentioned air distributing holes, between the external cylinder and intermediate cylinder an distributing chamber is set. Its structure is novel, and its oxygen dissolubility is high.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a self-suction gas-liquid two-phase nozzle with a convex ring structure. Background technique [0002] Gas-liquid two-phase mixing is a common mixing method, such as the gas-liquid mixed reaction process in the petrochemical industry, the mixed combustion process of fuel and air, the cooling of materials, the dehydration and drying process, etc. Aerobic biological treatment of organic wastewater is an environmental treatment technology that has been widely used and has good development prospects. The air flotation process of oil removal and suspended solids removal is also a unit operation commonly used in environmental engineering. The normal operation of these two processes, Both need to blow enough air into the system to mix the gas-liquid two-phase, and the degree of mixing directly affects the treatment effect. In the organic wastewater aerobic biological treatment device, a...
