The discharge of PM2.5 causes very big harm to human health, is the difficult problem in coal-burning power plant's pollutant control.The PM2.5 of coal-burning power plant discharge is divided into can filtering particle (PM) and condensable particle (secondary PM) two classes, wherein can filtering particle and the ratio of condensable particle be 1:3.And the main source of condensable particle is SO in flue gas
2the SO that partial oxidation forms
3with the sulfuric acid aerosol that moisture in flue gas forms, research is found in addition, the SO of the introducing of SCR denitrating catalyst in also can catalysis flue gas
2be oxidized to SO
3.Electrostatic precipitation and bag-type dust can not remove this part sulfuric acid aerosol particle, and WFGD is to SO
3removal efficiency is lower, causes PM2.5 to remove difficulty, conventionally need to after WFGD, add wet static dedusting (WESP) and remove sulfuric acid aerosol particle.SO
3acid mist causes corrosion to downstream flue and equipment, has increased the weight of the discharge of PM2.5 condensable particle simultaneously.Research finds that dry method flue gas desulfur device can effectively remove SO
3, realize SO except add WESP after WFGD
3remove outside, WFGD upstream add dry method FGD be also realize remove flue gas in SO
3effective ways.
