Abstract

The embodiment of the invention provides a double-chamber organic solid waste pyrolysis device and a pyrolysis method. The device comprises a hopper, a feeding system, a pyrolysis system, a solid collection system, a waste heat utilization system, a combustion system and a tail gas treatment system. The pyrolysis system mainly comprises a reaction chamber, a buffer chamber, a stirring paddle, a rotary inner cylinder and other auxiliary structures. After entering the reaction chamber, the organic solid waste raw material is stirred by the stirring paddle to be uniformly heated; after the raw materials are reduced, pyrolysis residues are fed into the buffer chamber for continuous pyrolysis, coke and residues are discharged after pyrolysis is completed, and the reaction chamber starts to feedfor the next round of pyrolysis; pyrolysis gas is used for combustion to provide energy, and the semi-self-heating pyrolysis process is achieved. After hot smoke generated by combustion supplies heatto pyrolysis and preheats cold air, the hot smoke is purified and emptied by the tail gas treatment system. The device has the advantages of wide material applicability, uniform reaction heating, high system heat and space utilization rate, clean discharge and the like.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of organic solid waste, in particular to a double-chamber organic solid waste pyrolysis device. The present invention also provides a pyrolysis method for organic solid waste using the dual-chamber organic solid waste pyrolysis device. Background technique [0002] Organic solid waste refers to solid organic matter that has lost its original use value or has not lost its use value but is discarded in production, living or other activities, mainly including domestic garbage, sludge, agricultural and forestry waste, etc. With the rapid development of my country's social economy, more and more organic solid wastes are produced in various fields such as industry, agriculture, and life. The treatment of organic solid wastes has begun to become a key issue related to the construction of ecological civilization in our country. [0003] Conventional treatment methods for organic solid waste in...
