Full-process waste incineration system

Abstract

The invention discloses a whole-process waste incineration system which comprises a waste pretreatment system, a waste incineration system, a waste incineration system and a waste incineration system. The waste incineration system comprises a waste incinerator (10), and a material inlet of the waste incinerator (10) is connected with a material outlet of the pretreatment drying kiln (9); the waste heat utilization system comprises a waste heat boiler (11), a flue gas inlet of the waste heat boiler (11) is connected with a flue gas outlet of the garbage incinerator (10), and a steam outlet of the waste heat boiler (11) is connected with a heat inlet of the pretreatment drying kiln (9); the waste incineration flue gas treatment system comprises a tunnel kiln (22), and the tunnel kiln (22) comprises a tunnel kiln main body structure; smoke exhausted by the waste heat boiler (11) is guided into the tunnel burning kiln body. According to the whole-process waste incineration system, the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a whole-process garbage incineration system. Background technique [0002] Due to the complex composition of waste materials, taking the waste incinerator burning municipal solid waste (low calorific value and high water content) as an example, due to the low calorific value and high water content of municipal solid waste, the combustion is incomplete, resulting in dioxin, dust , VOCs and acidic substances, etc., making it more difficult to deal with flue gas emissions. In order to purify flue gas, it is necessary to add heavy oil, natural gas, etc. to support combustion, so as to prevent incomplete combustion, consume a large amount of fossil energy, and have low economic benefits. [0003] Moreover, the waste incinerator of the waste incineration system produces low heat recovery and utilization efficiency of the high-temperature flue gas after the waste is...

AI Technical Summary

Problems solved by technology

[0002] Due to the complex composition of waste materials, taking the waste incinerator burning municipal solid waste (low calorific value and high water content) as an example, due to the low calorific value and high water content of municipal solid waste, the combustion is incomplete, resulting in dioxin, dust , VOCs and acidic substances, etc., making it more difficult to deal with flue gas emissions

In order to purify flue gas, it is necessary to add heavy oil, natural gas, etc. to support combustion, prevent incomplete combustion, consume a large amount of fossil energy, and have low economic benefits

[0003] In addition, the waste incinerator of the waste incineration system produces low heat recovery and utilization efficiency of high-temperature flue gas after the waste is burned, which also makes the economic benefit not high.
