Hazardous gas emission and blocking integrated device

Abstract

The invention discloses a hazardous gas emission and blocking integrated device. The device comprises a ball valve, a gas inlet pipe and a gas outlet pipe, wherein the gas inlet pipe and the gas outlet pipe are symmetrically arranged on the two sides of the ball valve and communicate with the ball valve, an orchid disc is installed inside the ball valve, four connecting blades are further arrangedon the edge of the orchid disc, a one-way valve is installed inside the air outlet pipe, symmetrical fixing blocks are welded in the pipe wall of the air inlet pipe, springs and a telescopic column are arranged on one sides of the fixing blocks, the two ends of the springs are connected with the fixing blocks and the telescopic column, and apply pressure to the fixing blocks and the telescopic column correspondingly, a sealing piece is arranged on the side face of the telescopic column, and the sealing piece is bonded with the telescopic column and partially extends into the ball valve. And therefore, good air tightness is achieved, meanwhile, gas overflow or backflow cannot be caused in the gas transferring process, emission and blocking can be achieved at any time through an external controller, and workers can be reminded.

Description

technical field [0001] The invention relates to the technical field of gas discharge devices, in particular to an integrated device for blocking hazardous gas discharge. Background technique [0002] With the rapid development of industrialization, chemical production is accompanied by a large number of dangerous gases, such as hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, etc. With the improvement of human awareness of environmental protection, these gases are being produced. Afterwards, it is collected by the collection device and transported to the waste gas treatment center for proper treatment. [0003] After searching, it was found that the invention of the patent number CN202305285U discloses a toxic gas collection device, which includes a reaction box, a pipeline, an exhaust fan, a differential pressure gauge and a collection box, and a carrier tray for placing reactants is arranged in the reaction box, A suction port is ...

AI Technical Summary

Problems solved by technology

However, after analysis, it is found that industrial hazardous gases need to be transported in the transfer purification equipment, and the gas will overflow due to poor sealing conditions. At the same time, the one-way backflow of the gas will also lead to low transmission efficiency. To flow and block at any time, the staff do not know when to discharge and block
