Abstract

The utility model provides a water quenching slag salvaging machine for liquid slag discharge, which comprises a slag salvaging machine main body, a hydraulic conveying system arranged at a feed port of the slag salvaging machine main body, a spraying pipeline arranged below the conveying system and used for fragmenting liquid slag into uniform size, and a dead steam discharge system arranged above the slag salvaging machine main body, a scraper slag salvaging device used for collecting salvaged slag is arranged in the slag salvaging machine body, and a double-turning-plate air locking discharging valve is arranged at a discharging port of the slag salvaging machine body. Belongs to the technical field of thermal engineering. The operation is stable and safe, the spraying pipeline is used for decomposing and salvaging the slag, and the problems of equipment failure caused by non-uniform granularity of the slag when the amount of the liquid slag is unstable and noise and steam generated when the liquid slag enters the slag salvaging machine are solved; a dead steam discharge system and a slag quenching water circulation system are used, so that the problem of heat exchange and scaling of circulating water in the slag conveyor is solved; the problem that liquid slag is caked on the chain is solved.
