工作原理
本项工艺是基于高级氧化(AOP)以及化学吸收法的基上,形D的有机气体深度治理工艺。
1.通过臭氧发生器产生的臭氧,在液相氧化剂存在的循环液中,通过扩散过程,达到均匀相,与通入的有机废气初步发生接触氧化反应。
2经初步氧化反应的气体,—部分截留在循环液中继续氧化;另一部分有机气体随紊留气体逆流而上,到达氧化填料区。大比表面积的催化填料使有机物在其附近聚集,加快反应速率,提高反应效率。
3.复配氧化剂在酸性或碱性环境中经高压喷嘴雾化,形成粒径很小的液雾,增加复配氧化剂及催化填料的接触面积。废气在催化剂填料的晶格上形成歧化电子云,加大传质面积,同时复配氧化剂在催化填料表面激发具有高电位(2.80eV)的羟基自由基(.OH),在界面加速电子转移,发生水分子、有机物的氧化还原反应。
4、大比表面积的催化剂结构以及整体塔内结构设计,增加废气与羟基自由基的反应时间,满足有机废气快速分解条件。将氧化填料区表面停留的大分子有机物分解成小分子有机物;经多次的催化氧化和多重反应,把有机废气彻底分解成COz和H:O;含卤素、杂原子的有机物最终分解成CO2.HzO和盐类。净化后气体中富裕的臭氧部分,在塔内氧化还原、最终达标排放。
该治理技术氧化彻底、转化率高、不产生二次污染且运行成本低,对大风量、组份杂的有机尾气具有良好的去除效果。
This process is based on the advanced oxidation {AOP) and chemicalabsorption method ,the formation of organic gas deep treatment process.1. The ozone generated by the ozone generator reaches a homogeneousphase through the diffusion process in the circulating liquid where the liquidaxcidant exists, and initially undergoes a contact oxidation reaction with theorganic waste gas passed in.
2.Part of the gas that has undergone the initial oxidation reaction is trappedin the circulating liquid to continue oxidation; the other part of the organicgas flows back up with the turbulent gas and reaches the oxidation packingarea.Catalytic fillers with large specific surface area can accumulate organicmatter in its vicinity，speed up the reaction rate and improve reactionefficiency.
3.The compound oxidant is atomized by a high-pressure nozzle in an acidic oralkaline environment to form a liquid mist with a small particle size, whichincreases the contact area between the compound axidant and the catalyticfiller.The exhaust gas forms a disproportionated electron cloud on the latticeof the catalyst filler to increase the mass transfer area.At the same time,thecompound oxidant excites hydroxyl radicals (.OH)] with a high potential(2.80ev) on the surface of the catalyst filler to accelerate electron transfer atthe interface.Redax reaction of water molecules and organic matter occurs.4.The catalyst structure with large specific surface area and the owerall towerinternal structure design increase the reaction time of exhaust gas andhydroxyl radicals and meet the conditions for rapid decomposition of organicexhaust gas. Decompose the macromolecular organic matter on the surface ofthe axidized packing area into small molecular organic matter; after multiplecatalytic oxidation and multiple reactions, the organic waste gas is completelydecomposed into COa and H:O; halogen and heteroatom-containing organicmatter is finally decomposed into COz,HzO and Salt. The rich ozone part ofthe purified gas will be oxidized and reduced in the tower and finallydischarged up to the standard.
The treatment technology has thorough oxidation, high conwersion rate, nosecondary pollution and low operating cost, and has a good remowal effect onorganic exhaust gas with large air wolume and mixed components.适用范围
