Description

technical field

[0001] The invention relates to a reactor for treating flue gas of a coal-fired boiler, in particular to a two-stage double-circulation spray packing composite absorption tower. Background technique

[0002] my country is a country with coal as the main energy source. The air pollutant SO produced by coal burning 2 and NOx have caused serious acid rain pollution in some areas of our country, which has brought serious harm to the local ecological environment. In addition, SO emitted into the air 2 And NOx and some volatile organic compounds can form fine particles through chemical reaction, forming PM2.5, which eventually leads to the occurrence of haze phenomenon, which seriously endangers human health. Thermal power generation occupies a dominant position in my country's power generation field. According to statistics, more than 70% of my country's electric energy comes from thermal power generation. for SO 2 The country has carried out comprehensive des...
