technical field

The invention relates to the technical field of exhaust gas denitrification, in particular to a catalyst reduction oxidation denitrification device.

Background technique

Thermal power denitrification refers to thermal power generation in order to prevent excessive NOx pollution of the environment after coal combustion in the boiler. The coal should be denitrified. It is divided into denitrification before combustion, denitrification during combustion, and denitrification after combustion, that is, removal of NOx in the flue gas ( Nitrogen oxides), this substance will form acid rain when it enters the atmosphere, and acid rain is very harmful to human beings. Therefore, the country has been promoting environmental protection. The flue gas that uses coal as fuel contains these substances, especially thermal power plants.

The existing destocking technology is divided into catalytic reduction technology and non-catalytic reduction technology. The catalytic reduction technology uses a reducing agent (NH3 urea) under the action of a metal catalyst to selectively react with NOx to generate N2 and H2O instead of being oxidized by oxygen. The existing catalytic reduction device is bulky, inconvenient to move, uses little space, and has low working efficiency. No dust treatment is carried out before catalysis, which affects the effect of catalytic reduction.
