Abstract

The invention discloses a low-temperature thin-layer quick-heating cascade anaerobic pyrolysis system which comprises a solid waste extrusion conveying system, a heating temperature control system anda heat preservation device. The solid waste extrusion conveying system and the heating temperature control system are arranged in the heat preservation device; pyrolysis gas outlets are formed in theheat preservation device; the solid waste extrusion conveying system is used for extruding and thinning the solid waste before conveying the solid waste; and the heating temperature control system isused for heating and pyrolyzing the extruded and thinned solid waste. According to the low-temperature thin-layer quick-heating cascade anaerobic pyrolysis system provided by the invention, the solidwaste is subjected to paving, extruding, thinning and heating, and then quickly heated and pyrolyzed; and particularly, roller sealers are arranged to form sub heating areas, so that the system has the advantages of being low in heating temperature, low in operation cost, high in heating speed, not prone to coking, high in adaptability and the like.

Description

technical field [0001] The invention relates to a solid waste pyrolysis system and belongs to the field of environmental protection solid waste treatment. Background technique [0002] The current solid waste treatment methods include landfill (large-scale composting), composting, incineration, pyrolysis and other methods. [0003] Landfill generally only solves temporary needs. Solid waste exists for a long time, and it will take several years to stabilize at the shortest. The environmental risk is high. After stabilization, with the development of society, most of them will eventually need to be incinerated, pyrolyzed, etc. after excavation. Eliminate this risk; composting realizes low-energy treatment of organic waste, but the treatment time is several months, the time is long, and the efficiency is low. After the organic matter is decomposed, if the raw material is not a safe raw material, the residue will eventually need to be pyrolyzed and incinerated; the reduction of...
