Method for Integrated control and recycle of flue gas pollutant of fire coal electric power plant, and special system thereof

The invention discloses a method for the integrated control and the resource of smoke gas pollution in the fire coal power station, which is characterized by the following: absorbing the pollution material (SO2, CO2, Hg,Pm2. 5) of coal burning by spraying amino solution as the ammonium salt form in the integrated absorption system after the tail of coal-burning boiler is removed dust; reducing the discharge of 100% SO2, 20%-95% carbon dioxide, 10%-80% Hg and 10%-70% Pm2. 5 in the smoke gas; acquiring high purity carbon dioxide by separating carbon dioxide absorbed as the ammonium salt form for industry, chemical industry, food processing industry and the oil displacement of oil extraction, wherein the dust concentration discharged by the defroster in the clean smoke gas is less than 40mg/Nm3, the escape ratio of amine discharged by the defroster in the clean smoke gas is less than 15mg/Nm3. The invention has the apparent advantages from the production ability aspect and the technology process, the economic an
