The concentration of ozone in the oxidation treatment is 200ppm~800ppm, and the oxidation treatment meets the discharge standard before being discharged. According to the concentration and flow rate of the exhaust gas to be treated. Different, ozone concentration can choose different data such as 200ppm, 300ppm, 400ppm, 500ppm, 600ppm, 700ppm, 800ppm.
本发明采用大功率高能紫外射线, 高能紫外射线光束能裂解恶臭废气如: 氨、 三甲胺、 硫化氢、 甲硫氢、 甲硫醇、 甲硫醚、 二甲二硫、 二硫化碳、 苯乙 烯、 H2S、 VOC类、 苯、 甲苯、 二甲苯, 将有机或无机高分子恶臭化合物长分 子链打断,裂解转化成呈离子状态的单分子恶臭废气污染物质混合气体。再利 用臭氧氧化处理, 对其进行强氧化反应, 使其生成、 转变成简单的、 小分子化 合物, 如 C02, H20等。 表 1列出了主要化学分子的结合能。 由于紫外射线的 光子能量大于等于 472 KJ/mol, 小于等于 800 KJ/mol, 由表 1中可知, 大多数 化学物质的分子结合能比 185nm及 230nm波长高能紫外射线的光子能量低, 所以, 采用紫外线能打断除碳、 金属外的大多数化学物质分子键。 表 1部分化学分子的结合能 The invention adopts high-power high-energy ultraviolet ray, and the high-energy ultraviolet ray beam can crack the odorous exhaust gas such as: ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, H 2 S, VOC, benzene, toluene, xylene, breaking the long molecular chain of the organic or inorganic high-molecular malodorous compound, and cracking and transforming into a single-molecule malodorous exhaust gas pollutant mixture gas in an ionic state.
