[0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam with certain thermal energy, high-temperature water or organic heat carrier. Boilers generally use raw coal as fuel. The flue gas emitted contains atmospheric pollutants such as sulfur dioxide, nitrogen monoxide and particulate matter, which has caused serious pollution to my country's atmospheric environment. Therefore, it is necessary to treat the flue gas emitted by the boiler, usually using dust removal, desulfurization and denitrification equipment for treatment.

[0003] However, the existing high-efficiency boiler dust removal, desulfurization and denitrification devices have the following disadvantages:
