Sintering machine head flue gas desulfurization and denitrification treatment device and treatment method thereof

Abstract

The invention discloses a sintering machine head flue gas desulfurization and denitrification treatment device and a treatment method thereof. The device comprises a dry desulfurization tower, a bag-type dust collector, a GGH flue gas heat exchanger, a low-temperature catalyst SCR reactor, a variable-frequency fan and a chimney which are sequentially communicated. The GGH flue gas heat exchanger is provided with a first input end, a first output end, a second input end and a second output end. The air outlet end of the bag-type dust collector is communicated with the first input end, the firstoutput end is communicated with the air inlet end of the low-temperature catalyst SCR reactor, the air outlet end of the low-temperature catalyst SCR reactor is communicated with the second input end, and the second output end is communicated with the variable-frequency fan. The dry desulfurization technology and the low-temperature SCR catalyst are combined for use, the stability of the system is improved, excessive consumption of a desulfurizing agent is avoided, and consumption of heating fuel is reduced.

Description

technical field [0001] The invention relates to the field of flue gas treatment and environmental protection equipment, in particular to a flue gas desulfurization and denitrification treatment device at a sintering machine head and a treatment method thereof. Background technique [0002] Flue gas pollutants from the head of the sintering machine are an important source of pollutants in metallurgical waste gas. In recent years, the state has paid special attention to the pollution control in the metallurgical field. During the production process of the sintering machine, sulfur oxides, nitrogen oxides and particulate matter are produced. Seriously endangering our living environment, acid rain, smog and other problems occur frequently. In order to cope with the environmental impact brought about by the production of sintering machines, the national environmental protection department has promulgated the guiding standards for the treatment of flue gas at the head of sintering...
