Abstract

The invention discloses an industrial waste cracking incineration exhaust gas denitration system. The system comprises a gas overheat protector, a thermal gas mass flow meter, a mixed gas flow rate control valve, a bag-type dust collector, a semiconductor pump rubidium vapor laser array decomposition reactor, a flue gas cooling system, an exhaust fan, and the like. According to the invention, high energy of rubidium vapor laser is creatively utilized. Under direct irradiation of rubidium laser, electrons in nitrogen oxide molecules in the exhaust gas are subjected to rubidium laser high-energy photon bombardment, such that energy level transition occurs. Therefore, the strength of N-O bond in the nitrogen oxide molecules is gradually reduced, and finally bond breakage and dissociation occur, such that the nitrogen oxides are decomposed into harmless nitrogen and oxygen. With the system, overheat protection can be carried out upon the entire system according to the inlet gas temperature of the industrial waste cracking incineration exhaust gas; and waste gas nitrogen oxide concentration can be regulated to a value within the concentration range of a system designed load.

Description

technical field [0001] The invention relates to an industrial waste cracking and incineration tail gas denitrification system, which belongs to the field of waste gas treatment in environmental protection. Background technique [0002] Nitrogen oxides (NitrogenOxides) is a major pollutant in the atmospheric environment, which includes a variety of compounds, such as nitrogen dioxide, nitrogen monoxide, dinitrogen oxide, dinitrogen trioxide, dinitrogen tetroxide, dinitrogen pentoxide etc. Except for nitrogen dioxide, other nitrogen oxides are extremely unstable, and will be converted into nitrogen dioxide or nitric oxide when exposed to light, humidity or heat, and nitrogen dioxide is the main form. [0003] The main sources of nitrogen oxides are divided into natural formation and human activities. Naturally emitted nitrogen oxides mainly come from the decomposition of organic matter in soil and oceans and the catalysis of lightning, which all belong to the nitrogen cycle pr...
