Description

technical field [0001] The invention relates to a circulating fluidized bed waste incineration exhaust gas comprehensive purification device and method, and belongs to the technical field of waste incineration pollutant control. Background technique [0002] As a resource that has not been fully developed and utilized, garbage can not be ignored for its resource reuse advantages after incineration and the resulting secondary pollution. The flue gas emitted after garbage combustion contains a large amount of harmful gases, not only contains a large amount of primary particulate matter, precursors of secondary pollutants such as HCl, SO 2 , NOx, heavy metals, polycyclic aromatic hydrocarbons and other organic pollutants, and dioxins are also produced in large quantities during the incineration process. In addition, in the waste incineration post-treatment process, attention should also be paid to the control of inhalable particulate matter PM10 and PM2.5. It is imperative to ...
