Abstract

The invention discloses a solid waste incineration flue gas purification treatment method so as to effectively control dioxin emission. The method comprises the following steps that dechlorination treatment is carried out on solid waste incineration flue gas, wherein the main removal target substance is hydrogen chloride; high-temperature flue gas dust removal purification treatment is conducted on the solid waste incineration flue gas after dechlorination treatment, wherein the operation is carried out in the process that the temperature of the solid waste incineration flue gas is still 400 DEG C or above. As dioxin is not likely to be formed on dust particles of the solid waste incineration flue gas through catalysis under the high-temperature state of 400 DEG C or above, at the moment,hydrogen chloride for synthesizing dioxin and the dust particles are subjected to gas-solid separation through high-temperature flue gas dust removal purification treatment, which is equivalent to that hydrogen chloride and the dust particles are separated before entering a proper temperature interval for synthesizing dioxin, and therefore the possibility of synthesizing dioxin by combining the separated hydrogen chloride with the dust particles is completely cut off.

Description

technical field [0001] The invention relates to the technical field of purification of flue gas from solid waste incineration, in particular to a method for purifying flue gas from solid waste incineration and a system for purifying flue gas from solid waste incineration. Background technique [0002] The disposal methods of municipal solid waste mainly include landfill, composting and incineration. Because incineration has incomparable advantages over other methods, it has been widely used in recent years. However, incineration will produce a large amount of solid waste incineration flue gas. In order to avoid secondary pollution to the environment, these solid waste incineration flue gases must undergo strict purification treatment to fully remove the pollutants before they can be discharged. The pollutants in the flue gas of solid waste incineration are mainly dust, sulfur dioxide and other acid gases and dioxins. Since dioxin is a highly toxic substance that is extreme...
