Description

Technical Field

[0001] The utility model relates to the field of environmental protection and air treatment equipment, in particular to nitrogen oxide treatment equipment. Background Art

[0002] Nitrogen oxide treatment equipment is used to control and reduce nitrogen oxide emissions from industrial emissions, traffic exhaust and other sources to protect the environment and improve air quality. The function of nitrogen oxide treatment equipment is to reduce or remove nitrogen oxide emissions generated in industrial production processes. These devices can convert nitrogen oxides into harmless substances through chemical reactions or physical processes, thereby reducing the impact on the environment and human health. These devices play a very important role in industrial production and help protect the environment and improve air quality.

[0003] However, in actual use, traditional nitrogen oxide treatment equipment mostly requires workers to manually spray urea solution or other purification solutions on nitrogen oxides to complete the purification work. However, this will bring a heavy workload to the workers, and the purification efficiency is also poor. In addition, most traditional nitrogen oxide treatment equipment does not have stirring equipment, so the purified solution after use may show solution sedimentation, which will block the liquid outlet and make the equipment unable to discharge the solution normally, and its practicality is poor.

[0004] Therefore, those skilled in the art provide a nitrogen oxide treatment device to solve the problems raised in the above background technology. Utility Model Content
