Novel denitration SCR reactor

Abstract

The invention discloses a novel denitration SCR reactor which comprises a reaction catalysis shell, a gas outlet section, a mounting door and a gas inlet section, wherein a gas inlet section is weldedon the surface of one side of the reaction catalysis shell; a first catalyst is fixed on the inner wall of the reaction catalysis shell; a retention mechanism is arranged on the inner wall of the reaction catalytic shell on one side of the first catalyst, a second catalyst is fixed on the inner wall of the reaction catalytic shell, a gas outlet section is welded on the surface of the reaction catalytic shell, and a mounting door is welded on the surface of the reaction catalytic shell on one side of the gas outlet section. According to the denitration SCR reactor, the denitration effect of flue gas is improved when the denitration SCR reactor is used; the phenomenon of chronic sintering of the first catalyst and the second catalyst due to over-high flue gas temperature when the denitration SCR reactor is used is avoided; the flue gas denitration quality is improved when the denitration SCR reactor is used, and the phenomenon that the action of the first catalyst and the second catalyst is affected by moisture when the denitration SCR reactor is used is avoided.

Description

technical field [0001] The invention relates to the technical field of denitration SCR reactors, in particular to a novel denitration SCR reactor. Background technique [0002] In order to implement the "Environmental Protection Law of the People's Republic of China", "The Law of the People's Republic of China on the Prevention and Control of Air Pollution" and Beijing's "Emission Standards for Air Pollutants from Stationary Internal Combustion Engines" (DB11-1056-2013), standardize the operation of the flue gas denitrification system of internal combustion units Maintenance and management, control of nitrogen oxide emissions from internal combustion units, improvement of environmental quality, and protection of people's health. Combining the nitrogen oxide emissions of internal combustion units and the current exhaust emission control technology of internal combustion engines, a new type of high-efficiency denitrification SCR reactor is developed and installed downstream of...
