Problems solved by technology

However, in practical applications, in addition to producing primary combustible gases such as hydrogen, carbon monoxide, and methane, a large amount of tar, tar condensate, and other heavy carbon gaseous substances and toxic substances of various complex components will inevitably be produced; The increase of the content of organic matter in the substance also increases the amount of production
Heavy carbon not only blocks equipment pipeline valves, corrodes equipment and devices, but also requires a lot of water washing, purification treatment and other related equipment to remove, otherwise it will cause secondary pollution; other harmful substances also need to invest a lot of deacidification, desulfurization, and destocking And other related equipment for processing, bringing "bottleneck" problems to the application of "three-in-one treatment" technology that uses pyrolysis and pyrolysis gasification to treat solid waste

Abstract

The invention provides an organic solid rubbish pyrolysis gas treatment device and a working method thereof and belongs to the technical field of environmental protection and resource utilization. Thedevice mainly comprises a wind distribution pipe, heat storage bodies and a removal agent supply system. The removal agent supply system comprises a removal agent storing tank, a liquid metering pumpand a removal agent spraying nozzle. A primary wind distributing and mixing area, a primary combustion area, a first heat storage body, a secondary wind distributing and mixing area, a secondary combustion area and a second heat storage body are sequentially arranged in the shell. The removal agent spraying nozzle sprays a removal agent into the secondary combustion area. The device is used for treating industrial organic solid rubbish, urban and rural domestic rubbish and the like, in mixed gas-state object obtained after being subjected to pyrolysis and pyrolysis gasification, online high-temperature continuous re-cracking is carried out on heavy carbon and poisonous and harmful substance, the heavy carbon is completely split and converted into combustible gas, and the combustible gas is subjected to oxygen-enriched combustion to generate high heat output. Other poisonous and harmful substance is subjected to the chemical reaction in a high-temperature environment by the adoption ofthe proper amount of the removal agent, and thus converted into solid particles and harmless gas.

Description

technical field [0001] The invention relates to an organic solid waste pyrolysis gas treatment device and a working method thereof, which belong to the technical field of environmental protection and resource utilization. Background technique [0002] At present, in the treatment of industrial organic solid waste, civil organic waste, medical waste, material industry, and agricultural waste biomass reduction, harmlessness and resource utilization (hereinafter referred to as "three-chemical treatment"), the use of The treatment methods of pyrolysis and pyrolysis gasification technology have many advantages over incineration treatment; such as: complete harmlessness, significant reduction, high resource utilization efficiency, and less toxic and harmful substances in tail gas, especially avoiding Produces highly toxic substances such as dioxins and furans. However, in practical applications, in addition to producing primary combustible gases such as hydrogen, carbon monoxide,...
