Gas water seal cleaning and poisoning preventing device for converter gas

The utility model relates to the technical field of steelmaking converter gas production safety, and particularly discloses a gas water seal cleaning anti-poisoning device for converter gas, which comprises a gas water seal tank and a drainage sampling pipe, the drainage sampling pipe is mounted on a cleaning pipeline of the gas water seal tank, and a drainage sampling valve is mounted on the drainage sampling pipe. The drainage sampling valve controls water and gas in the gas water seal tank to be discharged; the device overcomes the defects that a gas water seal is cleaned, water cannot be drained, and flanges at the bottoms of four chambers of the water seal cannot be detached, and can effectively achieve the effects of convenient water drainage, convenient operation, prevention and early warning, and reduction of the labor intensity of workers; the device overcomes the difficulty that an operator must disassemble the flange in the coal gas water seal drainage and coal gas detection sampling process, the d
