The invention relates to a method for double removal of particulate matter in a W-shaped flame furnace for synergistic nitrogen oxide ultra-clean emission. The invention adopts innovative technologies such as the double adsorption and removal technology of particulate matter and aerosol, the high-efficiency synergistic mechanism of deep purification of acid gas and aerosol and nitrogen oxides removal, etc., and designs a W-shaped flame furnace with double removal of particulate matter and synergistic nitrogen oxide supercharger. The method of net emission has been verified by engineering practice and achieved the expected effect. The invention is convenient for operation, maintenance and repair, low in initial investment, operation resistance and operation cost, and is suitable for the removal of ultrafine particles, acid gases and aerosols, especially nitrogen oxides, originally and secondary formed in the flue gas of the W-type flame furnace. Purification and ultra-clean emissions. |
