Title:
FLUE GAS MULTI-POLLUTANT SYNERGISTIC PURIFICATION PROCESS AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/088526
Kind Code:
A1
Abstract:
Provided in the present invention are a flue gas multi-pollutant synergistic purification process and apparatus: after denitrification treatment, adding an oxidation treatment system, and passing flue gas having undergone denitrification treatment through the oxidation treatment system, such that carbon monoxide in the flue gas is converted into carbon dioxide; the heat released during said process is directly used for raising the temperature of flue gas before entering the denitrification apparatus, reducing or even omitting the process of raising the temperature of the flue gas by means of external fuel heating. The present invention fully utilises the carbon monoxide in the flue gas, using the heat released during the conversion of carbon monoxide into carbon dioxide to achieve the objective of raising the temperature of the flue gas for denitrification treatment, saving or even eliminating the use of fuel whilst treating the carbon monoxide in the flue gas, and thereby reducing the pollution of the environment by the flue gas and reducing or even avoiding secondary pollution in the flue gas treatment process.
