Garbage incineration device in oxygen-enriched atmosphere and using method thereof

Abstract

The invention relates to the field of methods or equipment specially suitable for incineration of waste or low-grade fuel, in particular to a garbage incineration device in an oxygen-enriched atmosphere and a using method thereof. The garbage incineration device in the oxygen-enriched atmosphere comprises an incinerator (1), and is characterized in that the garbage incineration device further comprises a dust remover (2), a heat exchange device (3), a combustion-supporting fan (4), a purifier (5) and an oxygen generator (6), a flue gas outlet of the incinerator (1) is connected with an inlet of a flue gas pipeline of the heat exchange device (3) through the dust remover (2), an outlet of the flue gas pipeline of the heat exchange device (3) is connected with the purifier (5), and an oxygenoutlet of the oxygen generator (6) is connected with a flue gas delivering pipe (71) through an oxygen delivering pipe (72). The using method of the garbage incineration device in the oxygen-enrichedatmosphere is characterized in that the method is implemented according to the following steps of a, material preparing, b, incineration, c, heat exchanging, and d, flue gas exhausting sequentially.According to the garbage incineration device in the oxygen-enriched atmosphere and the using method thereof, full combustion is achieved, complete degradation is achieved, and adaptability is high.

Description

technical field [0001] The invention relates to the field of methods or equipment specially suitable for incinerating waste or low-grade fuels, in particular to a waste incineration device in an oxygen-enriched atmosphere and a method for using the same. Background technique [0002] At present, domestic waste incineration technology has been widely used in the treatment of municipal solid waste, but some waste sources are relatively scattered. During the incineration process of small-scale treatment, the flue gas takes away a lot of heat, and there is insufficient heat in the incineration process, so it is necessary to increase auxiliary fuel, etc. Measures, resulting in serious pollution in the incineration process, high incineration costs. Due to insufficient combustion, low temperature and serious pollution during the incineration process of ordinary small incinerators, the decomposition conditions of harmful substances such as dioxins are not good, and the high amount o...

[0002] At present, domestic waste incineration technology has been widely used in the treatment of municipal solid waste, but some waste sources are relatively scattered. During the incineration process of small-scale treatment, the flue gas takes away a lot of heat, and there is insufficient heat in the incineration process, so it is necessary to increase auxiliary fuel, etc. measures, resulting in serious pollution in the incineration process and high incineration costs

Due to insufficient combustion, low temperature and serious pollution during the incineration process of ordinary small incinerators, the decomposition conditions of harmful substances such as dioxin are not good, and the high amount of auxiliary fuel leads to high operating costs, making it difficult to promote
