Description

A hazardous waste incineration concentrated liquid recirculation device Technical Field

[0001] This utility model relates to the field of hazardous waste incineration technology, specifically to a hazardous waste incineration concentrated liquid recirculation device. Background Technology

[0002] Leachate re-injection technology is a method of injecting concentrated liquid generated during hazardous waste treatment back into an incinerator for further processing. Hazardous waste leachate or concentrate is injected into the incinerator and subjected to high-temperature pyrolysis. Under these conditions, the organic matter in the concentrate is decomposed into harmless substances such as water and carbon dioxide, thereby reducing the volume of leachate and lowering treatment costs. The ammonia nitrogen component in the concentrate is used as a denitrification agent, working synergistically with the SNCR process to effectively reduce nitrogen oxide emissions.

[0003] In the existing technology, the crushed hazardous waste is piled up in a pool and transported to the incinerator by a belt conveyor. Because the pool is large and the belt conveyor is not easy to move, the operators need to constantly transfer the hazardous waste from the pool to the belt conveyor. The automation level is low and the workload of the operators is increased. Summary of the Invention
