When an emergency occurs, part of the flue gas flows into the bypass pipe 19A cyclone spray washing tower 13 to reduce the work load of the bag-type dust collector 12; the flue gas treated by the bag-type dust collector 12 enters a cyclone spray washing tower 13 to further remove acidic gases such as HCL, HF and the like contained in the flue gas, enters a wire mesh demisting tower 14 to remove entrainment (fog drops) in the flue gas, and enters an activated carbon adsorption tower 15 to remove dioxin and heavy metal ions.
Because the flue gas is treated by a flue gas quenching tower 10, a dry deacidification tower 11, a bag-type dust remover 12, a rotational flow spray washing tower 13, a silk screen demisting tower 14 and an activated carbon adsorption tower 15, the temperature is reduced to below 70 ℃, the flue gas is heated by a flue gas heater 16 to rise the temperature, so that the temperature of the flue gas is higher than the dew point temperature by more than 50 ℃, and the flue gas detects CO and CO in the exhaust gas at a monitoring port at the outlet flue of a tail gas draught fan 172、NOx、O2、SOxThe concentration and the smoke concentration of the flue gas reach the emission standard of the environmental protection requirement, and then the flue gas is conveyed to a chimney 18 by the blast of a tail gas induced draft fan 17 for emission.
