Multistage air self-suction spraying device

Abstract

The invention belongs to an oxidization device for adding air in a solution during the chemical production, and in particular relates to a multistage air self-suction spraying device with simple structure, capability of processing inverse spraying of the solution, stable operation, low cost and high air sucking efficiency. The multistage air self-suction spraying device comprises a feeding hole, wherein the lower part of the feeding hole is sequentially provided with a first nozzle, a first mixing chamber, a second nozzle, a second mixing chamber and a discharging hole; the upper part of the first mixing chamber is provided with a first air inlet, and the upper part of the second mixing chamber is provided with a second air inlet; the first air inlet and the second air inlet are respectively connected with a share pipe connected with a solution searching tank through pipes; the solution searching tank is sleeved outside an exhaust hole at the top of an oxidization tank; and the top end of the solution searching tank is connected with air, and the bottom of the solution searching tank is provided with a U-shaped solution sealing pipe which is connected with the exhaust hole. The invention has the advantages of being capable of increasing air sucking efficiency of above 60 percent, automatically searching the solution inversely spraying out of the air inlet, saving cost and protecting environment.

Description

Technical field [0001] The invention belongs to an oxidation device for adding air to a solution in chemical production, and particularly relates to a multi-stage self-priming air spray device with simple structure, capable of treating solution back spray, stable operation, low cost and high air intake efficiency. Background technique [0002] The self-priming air injection device in the prior art only uses one air inlet, and the efficiency of sucking air is low. To achieve the purpose of oxidation, multiple ejectors are often required; and the solution is likely to fall from the air inlet when the equipment is unstable. When sprayed out, it not only pollutes the environment, but also wastes raw materials. Summary of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a multi-stage self-priming air ejection device with simple structure, capable of treating solution back spray, stable operation, low cost and high air i...

Problems solved by technology

[0002] The self-priming air injection device in the prior art only uses one air inlet, and the efficiency of air inhalation is low. Multiple injectors are often needed to achieve the purpose of oxidation; Spraying out will not only easily pollute the environment, but also cause waste of raw materials.
