A volume-reducing and harmless pyrolysis incineration purification system and process for rural domestic waste

Abstract

The invention discloses a volume-reduction and harmless rural domestic garbage pyrolytic incineration purification system and a technology thereof. The volume-reduction and harmless rural domestic garbage pyrolytic incineration purification system comprises a feeding device, a pyrolytic incineration device, a tar primary separation device, a tar secondary separation device, a dust removal device and an electric heating device. The volume-reduction and harmless rural domestic garbage pyrolytic incineration purification system is easy and convenient to operate and stable in operation, structuredesign is compact and miniaturized, mounting and operation are convenient, the application range is wide, adaptability is high, and various garbage can be treated. According to the technology, to-be-treated garbage materials are dried under the airtight condition and then subjected to pyrolytic treatment, and then solid substance generated by material pyrolysis is fully combusted; ash slag generated by combustion is extruded, crushed and cleared; flue gas generated by combustion and pyrolysis is subjected to water soaking for tar removing, spraying for tar removing, water showering for dust removing, electronic dust removing and electric heating and then is exhausted to the atmosphere; and the electric heating temperature is at least 850 DEG C. According to the technology, volume reductionof organic garbage can reach to 90% or above, dust and toxic and harmful gas in flue gas can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a volume-reducing and harmless rural domestic garbage pyrolysis incineration purification system and process. Background technique [0002] Great changes have taken place in the way of farmers' consumption. A large number of industrial and commercial products have poured into the rural consumer market, and industrial products are increasingly used in farmers' lives. At present, most villages across the country have basically completed the infrastructure for garbage collection, and realized the daily clearing of garbage. The villages have placed garbage bins, built garbage pools, equipped with garbage trucks, and have special personnel responsible for the daily collection and removal of garbage. The garbage in the village is brought into the garbage disposal system of districts, counties and towns to realize closed collection, unified transportation and harm...

AI Technical Summary

Problems solved by technology

However, traditional incineration not only has poor volume reduction effect, but also costs a lot, and the flue gas produced by incineration also has the problem of difficult purification.
