Air pollution occurs because of a large amount of nitrogen oxides and sulfur oxides in the atmosphere. Due to the occurrence of one pollution incident after another, scientists have proposed technologies to solve pollution according to the properties of these oxides, including absorption, adsorption, condensation, catalytic conversion, combustion, biological purification, membrane separation and dilution.

After being heated to a suitable temperature, the exhaust gas can enter the catalyst box 3. Then, the delivery pump 6 is started to extract the catalyst in the catalyst box 5, and after being transported through the delivery pipe 7, it is finally sprayed onto the exhaust gas through the atomizing nozzle 21. At this time, the catalytic work of the exhaust gas can be realized. Nitrogen and water will be produced after catalysis, and the nitrogen can be discharged from the outlet pipe 4.
