一、设备介绍   本净化器是一款专为工业废气专业处理车间因生产产生的烟尘及轻质颗粒而设计的一体化净化装置。设备核心部件主要采用光氧装置或水湿式，既能有效去除废气中的有害物质和污染颗粒等，又能降解各种异味和各种含金属加工厂生产出的有毒有害气体。二、工作原理   废气在引风机的负压作用下先进入光氧装置，光氧主要利用特制的高能高臭氧UV紫外线光束照射废气，裂解工业废气如：氨、三甲胺、硫化氢、甲硫氢、甲硫醇、甲硫醚、乙酸丁酯、乙酸乙酯、二甲二硫、二硫化 碳和苯乙烯、硫化物H2S,VOC类、苯、甲苯、二甲苯的分子链结构，使有机或无机高分子恶臭化合物的分子链在高能紫外线的光束的照射下降解转变成低分子 化合物，利用高能高臭氧UV紫外线光束分解空气中的氧分子及水分子产生游离氧（活性氧）和OH自由基，因游离氧和所携正负电子不平衡所以需与氧分子结合，进而产生臭氧。众所周知臭氧对有机物具有极强的氧化作用，对工业废气及其它刺激性异味有立竿见影的清除效果。进入高效填料塔。在填料塔的上端，喷头喷出吸收液均匀分布在填料上,废气与吸收液在填料表面上充分接触，发生反应。废气中的易溶于水的HCL、NO2、NH3等酸性物质几乎全被溶解在吸收液里，并与吸收液反应，生成无害的盐类和水，从而达到净化废气的目的。净化后的气体会饱含水份，经过塔顶的除雾装置去除水份后直接排放到大气中。吸收液根据污染物性质配制，可循环使用。三、应用范围  广泛应用于化工、电子、金属加工、烟草、玻璃、制药、食品加工、净化室等因生产产生的废气或不锈钢及管道加工、铝等金属焊接时产生的含铅、锡等烟气、废气或粉尘或烟雾处理场所。One、Equipment introductionThe purifier is an integrated purification device specially designed for industrial waste gas to deal with smoke and light particles produced in workshop. The core components of the equipment are mainly using the light oxygen device or water wet type, which can effectively remove the harmful substances and pollution particles in the waste gas, but also can degrade various odor and all kinds of toxic and harmful gases produced by various metal processing plants.Two、Working principleThe exhaust gas is first entered into the oxygen device under the negative pressure of the fan. The light oxygen is mainly irradiated by the special high-energy and high ozone UV ultraviolet light beam. The pyrolysis industrial waste gases such as ammonia, trimethylamine, hydrogen sulfide, methyl thiohydrin, methionyl alcohol, methionine, butyl acetate, ethyl acetate, two a, two sulfur, carbon disulfide and styrene are used. The molecular chain structure of sulfides H2S, VOC, benzene, toluene and xylene makes the molecular chain of organic or inorganic polymer odour compounds decompose into low molecular compounds under the irradiation of high energy ultraviolet light, and uses high energy high ozone UV ultraviolet light to decompose oxygen molecules and water molecules in the air to produce free oxygen (activity). Oxygen and OH radicals, due to the imbalance of free oxygen and positive and negative electrons, need to combine with oxygen molecules to produce ozone. As we all know, ozone has a strong oxidation effect on organic compounds, and has instant effect on industrial waste gas and other irritating odors. Enter the high efficient packing tower. At the upper end of the packed column, the nozzle sprays out the absorption liquid evenly distributed on the packing, and the exhaust gas and the absorption liquid are fully contacted on the surface of the packing, and react. The acidic substances, such as HCL, NO2 and NH3, which are soluble in water, are almost completely dissolved in the absorption liquid and react with the absorption liquid to produce harmless salt and water, thus the purpose of purifying the waste gas is achieved. The purified gas will be full of moisture and will be discharged into the atmosphere directly after removing the moisture from the mist eliminator at the top of the tower. The absorption liquid is prepared according to the nature of pollutants and can be recycled.Three、The scope of applicationIt is widely used in chemical, electronic, metal processing, tobacco, glass, pharmaceutical, food processing, purification room and other products produced by the production of exhaust gas or stainless steel and pipe processing, aluminum and other metal welding of lead, tin and other flue gas, waste gas or dust or smoke treatment places.
