Refuse derived fuel (rdf) pyrolysis gasification system

Abstract

The invention discloses a garbage derived fuel (RDF) pyrolysis gasification system, which belongs to the field of urban domestic garbage treatment. It mainly includes a feeding device, a waste heat boiler and a cold slag system; it is characterized in that it also includes a pyrolysis gasifier and a high-temperature separator, and a fluidized bed is arranged at the bottom of the pyrolysis gasifier; The pyrolysis gasifier is connected to the pyrolysis gasifier, the pyrolysis gasifier is connected to the waste heat boiler through a high temperature separator, and the cold slag system is connected to the pyrolysis gasifier and the slag discharge device of the waste heat boiler respectively. The invention has simple structure and reliable operation, and realizes resource utilization, reduction and harmless treatment of municipal domestic garbage. The invention is mainly used for the treatment of municipal solid waste.

Description

Technical field [0001] The invention belongs to the field of municipal solid waste treatment, in particular, it relates to a refuse derived fuel (RDF) pyrolysis gasification system. Background technique [0002] With the ever-increasing national environmental protection requirements and the acceleration of the urbanization of the population, the amount of urban waste has increased rapidly. The annual output of urban domestic waste in my country is as high as 160 million tons, and it is increasing at a rate of more than 10% every year. It is expected that by 2030, the city The annual output of domestic waste will reach 409 million tons. The issue of urban garbage disposal has attracted more and more attention from government departments. Governments and departments at all levels have invested a lot of manpower, material and financial resources in the recycling, transportation and treatment of urban garbage, which has enabled my country's urban garbage disposal work to achieve consi...

Problems solved by technology

However, due to my country's national conditions, unsound garbage classification standards, insufficient publicity, inadequate sorting, transfer and terminal treatment facilities, and citizens' living habits, many factors have caused high investment and low output in urban waste treatment, seriously restricting my country's urbanization development process

[0003] At present, my country's urban waste treatment technologies mainly include three forms: landfill, composting and incineration. Landfilling will occupy a large amount of land, which will easily cause secondary pollution of soil and water sources, and destroy the ecological balance; the composting time period is long, and water, soil and gas are seriously Pollution, and the types of garbage that can be processed are limited; incineration will produce highly toxic, non-degradable carcinogens, dioxins, and dozens of harmful gases
