Small-scale efficient domestic garbage gasification incineration system and incineration method

Abstract

The invention discloses a small-scale efficient domestic garbage gasification incineration system and an incineration method. The small-scale efficient domestic garbage gasification incineration system comprises a domestic garbage gasification incinerator, a domestic garbage pretreatment system, a heat exchanger and a flue gas treatment system. The small-scale efficient domestic garbage gasification incineration system and the incineration method have the advantages that the defects of high pollutant content of flue gas and incineration incompleteness, unthoroughness and nonuniformity caused by irrationality and nonuniformity of feeding in incineration and lack of pretreatment of the domestic garbage in use of existing small-scale domestic garbage incineration systems can be overcome, and the domestic garbage gasification incineration system is innovatively designed on the basis of an original biofuel gasifier; a storage bin for pretreatment of original domestic garbage, a discharging machine and garbage drying and conveying devices are designed, and a gasification furnace core which realizes uniform and quantitative feeding and provides strong turbulence air to enable continuous turnover and quick combustion of domestic garbage is designed.

Description

technical field [0001] The invention relates to the field of garbage incineration, in particular to a small-scale household garbage gasification incineration system and an incineration method. Background technique [0002] Most of the existing domestic small-scale domestic waste gasification incineration systems adopt the one-step gasification and melting incineration technology, that is, the drying, pyrolysis, gasification, and combustion of domestic waste are completely completed in one device, and in order to increase the combustion temperature, a auxiliary fuel. Due to cost and structural constraints, most of the existing domestic small-scale domestic waste gasification incineration systems are difficult to meet the requirements of the "Pollution Control Standards for Domestic Waste Incineration" (GB18485-2014). Contents of the invention [0003] The purpose of the present invention is to overcome the problem of non-uniform and unreasonable feeding in the small domest...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the small-scale domestic waste incineration system does not pretreat domestic raw waste (drying and dehydration, fermentation, pyrolysis), and adopts one-step gasification and melting incineration technology. Uneven, incomplete, incomplete, and high levels of flue gas pollutants. On the basis of the original biofuel gasifier, an innovative design of the domestic waste gasification incineration system is provided; a small-scale domestic waste gasification incineration system and Incineration method; design the storage bin for pretreatment of domestic waste, the discharge machine and the waste drying and conveying device, and design the uniform and quantitative feeding, and provide strong turbulent air supply, so that the domestic waste can be continuously turned and burned rapidly The "gasification furnace core", thus eliminating the shortcomings of the one-step gasification melting incineration technology
