The main reason is that my country's coal-fired energy structure is the main energy structure. The flue gas emitted from coal combustion contains a large amount of dust, sulfur dioxide, nitrogen oxides and other impurities. Therefore, it is imminent to control the emission of dust, sulfur dioxide and nitrogen oxides. A lot of experimental studies have been done on the problem of dust removal, desulfurization and denitrification of power plant flue gas. However, the traditional purification system, dust removal device, desulfurization device and denitrification device can only work alone, and the operation and maintenance costs are high. With desulfurization and denitrification, it can greatly save operating costs and space, and at the same time improve the efficiency of flue dust treatment.
