Method and equipment for purifying tail gas generated by burnning garbage

Abstract

A device of purifying waste gas of garbage-burning is prepared as setting smoke inlet at top end of cooling tower; setting water spraying nozzle opposite to flowing direction of smoke; setting S form flue pipe between cooling tower bottom and top of bag-type collector; setting lime powder inlet at bottom section of said flue pipe, iron fly ash inlet at middle section of said flue pipe and activated carbon inlet at top section of said flue pipe; setting filter material layer in bag-type collector and setting purified gas outlet at top side of bag-type collector.

Description

technical field [0001] The invention relates to the technical field of combustion boiler tail gas purification and dust removal, in particular to a method and a device for deacidifying waste incineration tail gas, removing adsorbents such as inhalable particles and dioxins, and the like. Background technique [0002] Air pollution has always been the focus of environmental protection work in many countries in the world, and more than 200 flue gas desulfurization technologies have been developed successively by various countries. However, there are only a dozen kinds that can be applied industrially. For the tail gas produced by waste incineration, in addition to conventional coal-fired flue gas pollutants such as nitrogen oxides, sulfur oxides, fine particles and heavy metals, it also contains a larger amount of harmful substances such as elemental chlorine, hydrogen chloride, and dioxins. Desulfurization and dust removal technology cannot meet the strict purification requi...

AI Technical Summary

Problems solved by technology

Although the above method can remove the acid gas and fly ash in the tail gas, it has the problems of high equipment investment and operation cost, large floor area, and inability to effectively remove fine dioxin particles produced by waste incineration.
