Continuous high-temperature oxygen-isolated carbonization process for treatment of municipal solid waste and apparatus used therein

Abstract

The invention is a continuous carbonization process directed at municipal solid waste and an apparatus used therein. The process can mainly overcome problems occurred in treatment of municipal solid waste in the prior art, e.g., generation of oncogenic dioxin in burning of municipal solid waste. The process can realize pollution-free treatment of garbage. The invention has the following advantages: combustible gas produced in cracking and carbonization of municipal solid waste under high temperature and anaerobic conditions is used as an energy source for a system, thereby realizing self-sufficiency of energy; the anaerobic condition can well inhibit generation of dioxin; treating flow of the process is simple and stable, and long-time continuous treatment of municipal solid waste is realized; drying of municipal solid waste, deodorization of gas, circulation of heat and the like are realized.

Description

technical field [0001] The invention relates to a continuous high-temperature oxygen-insulated carbonization device for processing urban domestic garbage and a process thereof. Background technique [0002] Stimulated by the prosperity of the contemporary economy, people's living standards have been greatly improved, and the population and urban land have continued to increase, which has led to the increasingly prominent problem of urban garbage disposal. The demand for land for landfill and the shrinkage of the available land area caused by urban expansion have become a pair of constantly intensified contradictions. At the same time, the incineration of garbage will bring terrible dioxins, which will endanger human health. Therefore, people urgently need a new type of environmentally friendly waste treatment process to achieve zero emission and low energy consumption in waste treatment, so that urban waste is no longer an obstacle to urban development.
