Abstract
A system for integrated removal of multiple pollutants includes an economizer, an air preheater, an electrostatic precipitator, a flue gas cooler and a low-temperature adsorber; the economizer has a shell side inlet for feeding boiler flue gas, a tube side inlet for feeding boiler feedwater, and a shell side outlet connected to a tube side inlet of the air preheater; the air preheater has a shell side inlet for introducing boiler intake air, and a tube side outlet connected to the electrostatic precipitator; the electrostatic precipitator has a dust discharge port at a bottom thereof and a flue gas outlet connected to the flue gas cooler; the flue gas cooler has a condensate outlet at a bottom thereof and a cold flue gas outlet at a top thereof and connected to the low-temperature adsorber; and the low-temperature adsorber has a purified flue gas outlet at a tail thereof.
