Embodiment Construction

[0020] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0021] Such as figure 1 As shown, the present invention has a garbage incineration treatment system with a high-temperature dust collector, including a furnace (15), a second-stage dust collector (11), a third-stage dust collector (9), and a furnace (15) of the garbage incinerator system. The lower part is respectively connected with the garbage feeding hopper (16) and the slag discharge pipe (2), communicated with the blower (18) through the primary air pipe (1) and the secondary air pipe (17), and the upper part of the furnace (15) It is connected with the high-temperature dust collector (14), and the lower part of the high-temperature dust collector (14) is connected with the first-stage ash storehouse (5) through the heat exchanger (3). The inlet of the flue (13) is connected, the o...

Abstract

The invention provides a waste incineration treatment system with a high-temperature dust remover. Flue gas produced by waste incineration is exhausted after being subjected to multistage dust removal purification, first-stage dust removal is completed by the high-temperature dust remover, and collected fly ash is less in dioxin content and capable of being recycled; low-temperature dust removal is adopted by second-stage dust removal and third stage dust removal, the dust removal efficiency is high due to the combination of the second-stage dust removal and the third-stage dust removal, the dust content and dioxin content of the exhausted flue gas are low, and the flue gas is cleaner; activated carbon is sprayed into the flue gas at an inlet of a third-stage remover, dioxin in the flue gas is adsorbed, activated carbon is collected by the third-stage remover and sent back to f hearth of an incinerator, dioxin adsorbed by the activated carbon is disintegrated at high temperature, and the toxicity is removed. The waste incineration treatment system with the high-temperature dust remover has the advantages that the fly ash collected through high-temperature dust removal can be recycled, dioxin adsorbed by the activated carbon is disintegrated at high temperature after being sent back to the hearth, the total quantity of dioxin exhausted from waste incineration is effectively reduced, and the adverse effect of waste incineration on the environment is reduced.

Description

technical field [0001] The invention relates to the fields of garbage incineration and pollutant control, in particular to a garbage incineration treatment system with a high-temperature dust collector. Background technique [0002] Waste incineration has obvious advantages in terms of reduction, harmlessness and resource utilization, and has been widely used in the European Union and Japan. With the development of urbanization in China, the land for landfill is decreasing day by day, and more and more municipal waste is disposed of by incineration. [0003] Garbage contains organic matter and chlorine, and the flue gas produced by waste incineration contains halogenated compound dioxin, which is a very toxic organic matter and needs to be controlled during the process of waste incineration. According to the formation mechanism and physical and chemical properties of dioxins, China's "Standards for Pollution Control of Domestic Garbage Incineration" (GB18485-2014) compilati...
