Technical Field

[0001] The utility model relates to the technical field of flue gas denitrification and dust removal devices, and specifically relates to a flue gas denitrification and dust removal device. Background Technique

[0002] During the production process of a kiln, a large amount of nitrogen oxides will be contained in the flue gas discharged. Nitrogen oxides are one of the main pollution sources causing air pollution. If they are discharged beyond the standard without treatment, environmental pollution problems such as acid rain and photochemical smog will be caused. Therefore, it is necessary to carry out denitrification treatment on the polluted flue gas of the kiln. In the existing flue gas denitrification and dust removal devices, when spraying treatment agents, the spraying angle of the spray head is fixed, resulting in a limited spraying range. As a result, the treatment agent in the spraying process is not in sufficient contact with the flue gas, and then the purification is not thorough enough, which is not convenient to use. Therefore, we propose a flue gas denitrification and dust removal device. Content of the Utility Model
