The invention discloses a low-temperature drip absorption type catalytic denitration method, which solves the problems of low operating cost of flue gas denitrification and low denitrification efficiency of high-humidity and low-temperature flue gas in the prior art, and has temperature requirements for flue gas It has the advantages of low cost, simple treatment process, low operating cost, stable denitrification effect and less water consumption. The technical scheme is: when the low-temperature flue gas flows through the catalyst layer, water mist is continuously sprayed on the catalyst layer to keep the catalyst layer in a wet state, NO in the flue gas is oxidized to NO 2 under the catalytic action of the catalyst, and the generated NO 2 is Water mist absorption. |
