Abstract
The present invention discloses a method and device for purifying CO from a flue gas and coupling-suppressing white fog, where the flue gas is introduced into a ceramic honeycomb carrier coated with a CO catalyst, sufficient O2 in the flue gas is utilized to generate CO2 from a low concentration of CO through catalytic oxidation, so as to achieve the purpose of purifying CO, and the flue gas is heated up by the heat released from the catalytic oxidation reaction to more than 110° C. and then discharged into the air, which meets the temperature requirement of coupling-suppressing white fog; the device includes a CO concentration sensor, a temperature sensor, a CO catalytic oxidation layer, an oxidation reaction tower, a desulfurized sintering flue gas, a packing layer I, a packing layer II, a chimney, and a solenoid valve II.
