Integral flue gas denitration device filled with denitration catalyst and provided with catalyst coating

Abstract

The invention discloses an integral flue gas denitration device filled with denitration catalyst and provided with catalyst coating. The integral flue gas denitration device comprises side frames anda heat-exchange core; the side frames are arranged on two opposite sides of the heat-exchange core; four corners of the heat-exchange core are positioned and fixed through corner posts correspondingly; the heat-exchange core comprises a plurality of heat-exchange plates, spoilers respectively arranged between the heat-exchange plates, edge connection bolting assemblies, corner connection bolting assemblies and edge sealing strips; the optional adjacent heat-exchange plates of the heat-exchange plates form flue gas passages and cool fluid passages, the flue gas passages and the cool fluid passages are crossed mutually but not communicated mutually; the flue gas passages is filled with the denitration catalyst, and the surfaces of the heat-exchange plates are coated with the catalyst coating. The integral flue gas denitration device is reasonable in structure and convenient to manufacture, can not only recover exhaust heat of flue gas but achieve denitration and realize denitration and heat exchanging integrally; its floor occupation is saved, and the catalyst filling the flue gas passages is convenient to load and unload.

Description

technical field [0001] The invention relates to an integrated flue gas denitration device loaded with a denitration catalyst and a catalyst coating. Background technique [0002] Industrial furnaces are major energy consumers and pollution emitters in all walks of life, generally accounting for 50% to 70% of the energy consumption of the entire plant, and are almost the source of all air pollutants. [0003] Energy saving and emission reduction of industrial furnaces is very important. [0004] Among the common denitrification technologies, according to the formation mechanism of nitrogen oxides, the technical measures for reducing nitrogen and emission can be divided into two categories: [0005] One is governance from the source. Controls the formation of NOx during combustion. Its technical measures: ① low-nitrogen burner; ② stepped burner arrangement, layered and segmented combustion, and controlled combustion temperature; ③ flue gas recirculation, etc. [0006] The ...
