Municipal solid waste heat accumulating type gasification and melting incineration system

Abstract

The invention discloses a municipal solid waste heat accumulating type gasification and melting incineration system comprising a gasification and melting incinerator; the gasification and melting incinerator comprises a high-temperature air inlet and a high-temperature smoke outlet; the high-temperature smoke outlet is connected with the inlet of a high-temperature cyclone dust collector; the outlet of the high-temperature cyclone dust collector is divided into two paths, wherein one path is connected with the smoke side inlet of a first high-temperature air heat accumulating device and the other path is connected with the smoke side inlet of an exhaust-heat boiler; the smoke side outlet of the exhaust-heat boiler is connected with the smoke side inlet of a second high-temperature air heat accumulating device; the smoke side outlet of the second high-temperature air heat accumulating device and the smoke side outlet of the first high-temperature air heat accumulating device are combined into a whole and are connected with a bag type dust collector, a draught fan, a desulfurizing tower and a chimney in sequence. A heat accumulating type high-temperature air burning technology and agasification and melting incineration technology are combined, and two sets of high-temperature air heat accumulating devices sufficiently absorb burning heat, and thereby, auxiliary fuel consumptionis low, and the content of heavy metals and dioxins in ash smoke is low.

Description

technical field [0001] The invention relates to a treatment device for urban living garbage, in particular to a regenerative gasification, melting and incineration system for urban living garbage. Background technique [0002] With the improvement of people's living standards and the acceleration of urbanization, the increasing amount of municipal solid waste has become a bottleneck that seriously restricts urban development. [0003] In the prior art, it is necessary to add a large amount of coal and other auxiliary fuels to process waste through waste incineration technology, which consumes a large amount of precious energy, and the content of heavy metals and dioxins in fly ash is high. Contents of the invention [0004] The object of the present invention is to provide a regenerative gasification-melting incineration system for municipal solid waste, which combines regenerative high-temperature air combustion technology with gasification-melting incineration technology...
