| titleOfInvention | A kind of method of sulfur trioxide in removing coal-fired flue-gas |
| abstract | The invention proposes a kind of methods of sulfur trioxide in removing coal-fired flue-gas, according to the concentration of sulfur trioxide in selective catalytic reduction (SCR) denitration outlet flue gas, the good stripping liquid of ejection arrangement in flue gas into the exhaust gases passes between selective catalytic reduction (SCR) denitration outlet end and air preheater, the amount of injection of stripping liquid is 1-20 times of the molal quantity for the sulfur trioxide that the position needs to deviate from per unit volume flue gas.Gas liquid reaction occurs by the sulfur trioxide in stripping liquid and flue gas, the sulfur trioxide in flue gas is removed.Stripping liquid enters flue in a manner of spraying, and is atomized into droplet, forms minimum absorbent granules after evaporating in high-temperature flue gas.Particle is with respect to large specific surface area, and dispersibility is more preferable in flue, and contact sulfur trioxide is more abundant, it reacts more abundant, to considerably reduce the concentration of sulfur trioxide in flue gas, reduces the generation of ammonium hydrogen sulfate, avoid the corrosion of air preheater and the generation of clogging. |
