The invention relates to a device and a method for desulfurization and dust removal by spraying quick lime powder with supersaturation water and belongs to the technical field of environmental conservation, desulfurization and dust removal. The device comprises an electrostatic dust remover, a flue and a bag-type dust remover, wherein the electrostatic dust remover is connected with one end of the flue, the bag-type dust remover is connected with the other end of the flue; and the device is also provided with a water spraying and atomizing system and a fly ash recirculating system, wherein the water spraying atomizing system is opened at the end, close to the electrostatic dust remover, of the flue, the water spraying atomizing system sprays water mist to the flue, the fly ash recirculating system is opened at the end, away from the electrostatic dust remover, of the flue, the fly ash recirculating system is connected with the bag-type dust remover, and the fly ash recirculating system sprays the mixture of CaO and fly ash to the flue. The fly ash is the ash in an ash bucket of the bag-type dust remover.
Description
technical field [0001] The invention relates to a supersaturated water injection quicklime powder desulfurization and dust removal device and method, belonging to the technical field of environmental protection dust removal and desulfurization. Background technique [0002] At present, most of China's power energy supply comes from coal-fired power plants, and for a long period of time in the future, coal-fired power generation will still be the main power supply method in my country. SO emissions from coal combustion 2 It accounts for 87% of the total emissions from various pollution sources (fuel combustion sources, industrial waste gas sources, mobile sources) (accounting for 93% of fuel combustion emissions). With the increase of sulfur dioxide emissions in my country, it is far higher than the environmental carrying capacity, resulting in SO 2 The acid rain pollution caused by it is serious, and the area of acid rain accounts for 30% of the country's land area, beco...
