Abstract

The invention discloses an exhaust gas spraying pressure protection device. The device comprises a water-sealed tank and at least one air inlet assembly, wherein the water-sealed tank is filled with sealing liquid, and a water outlet is formed in the side wall of the water-sealed tank; the air inlet assembly comprises an air inlet pipe and an air pressure part arranged in the air inlet pipe, the air outlet end of the air inlet pipe is inserted into the water-sealed tank, at least one air outlet hole is formed in the circumferential outer wall of the air outlet end of the air inlet pipe and located below the liquid level of the sealing liquid, the air pressure part comprises a sealing part and an elastic part, and the sealing part is arranged in the air inlet pipe in a sliding manner and is tightly connected with the inner wall of the air inlet pipe, so that a path between the air inlet end of the air inlet pipe and the air outlet hole is opened and closed through sliding of the sealing part; the elastic part is arranged at one side, away from the air outlet hole, of the sealing part, connected to the inner wall of the air inlet pipe and the sealing part and used for providing resilience force after the sealing part slides. The exhaust gas spraying pressure protection device can effectively prevent exhaust gas in equipment from directly passing through the water-sealed tank.

Description

technical field [0001] The invention relates to the technical field of waste gas spraying, in particular to a gas pressure protection device for waste gas spraying. Background technique [0002] In the process of scrubbing the exhaust gas, the air pressure may be too high in some equipment for treating the exhaust gas, exceeding the set air pressure of the equipment. Generally, the excess gas in the equipment is discharged through the water sealing tank, so as to reduce the size of the equipment. air pressure inside. [0003] Announcement No. CN208442843U discloses an explosion venting tank, which includes a tank body, an upper sealing head and a lower sealing head arranged on the tank body. There is an air inlet pipe and an air outlet pipe connected to the inside of the tank body, the tank body is filled with water sealing liquid, the lower end of the air inlet pipe is lower than the liquid level of the water sealing liquid and the lower end of the air outlet pipe is highe...
