臭氧分解催化剂 1.工作原理及流程Operation and Process
臭氧（O3）是氧的同素异形体，它是一种具有特殊气味的淡蓝色气体。臭氧是一种强氧化剂，它在水中的氧化还原电位为2.07V，仅次于氟（2.5V），其氧化能力高于氯（1.36V）和二氧化氯（1.5V），能破坏分解**的细胞壁，很快地扩散透进细胞内，氧化分解**内部氧化葡萄糖所必须的葡萄糖氧化酶等，也可以直接与**、病毒发生作用，破坏细胞、核糖核酸（RNA），分解脱氧核糖核酸（DNA）、RNA、蛋白质、脂质类和多糖等大分子聚合物，使**的代谢和繁殖过程遭到破坏。可见，臭氧浓度过高对环境及人体健康有很大影响，而高浓度臭氧的鱼腥味也让人们难以忍受。
O3 is the allotrope of oxygen with special smell and light blue color. While O3 is of strong oxidant that it could destroy cytoderm and enter cells rapidly, then decomposite glucose oxidase, also O3 could directly react with germ and virus so that to destroy normal cell, RNA etc, which is harmful to environment and human health.
Ozone decomposition catalyst plays important role of decomposing ozone into oxygen.
Reaction formula: O3 O2
通常干燥空气或干燥氧气作通过放电后会产生臭氧。如大量复印机、印刷机、传真机等机器,以及吸尘器、空气清洁器的使用,通过电晕放电而产生臭氧；此外，臭氧****领域在**后会残留高浓度臭氧。
臭氧分解催化剂可以加速臭氧快速分解为氧气，从而减小臭氧的危害性。
Usually dry gas and dry oxygen will produce ozone after electrical release, such as copier, printer, fax machine, dust collector, air cleaner will produces ozone while using; besides, in ozone sterilizing industry, there is high concentration ozone left.
含臭氧废气经干燥器（内放置分子筛、硅胶等干燥剂）除湿后进入催化反应器，催化处理干净后排空。淀粉碘化钾溶液不变色则为臭氧完全净化。
Operation Process: after drying, waste gas containing ozone enter catalyst reactor through the drier (contains desiccant like molecular sieve, silica gel), and then discharge. It means ozone has been purified when starch potassium iodide keep its color.
2.工艺特点Operation Properties
技术特点为：① 分解能力强；② 耐湿性能强，可在相对湿度90%的高湿度条件下反应；③分解后臭氧浓度低。
采用型臭氧分解催化剂可快速使臭氧发生分解，使用温度仅为室温（当然温度越高分解越快）；催化剂除O3能力＞3000mg O3废气/g催化剂；臭氧分解效率：＞95%；使用空速：＞10000h-1；经催化剂分解后臭氧的浓度小于0.10 ppm。
1) This catalyst has outstanding composition capacity
2) Good moisture-resistant that workable at 90% relative humidity
3) Excellent performance with competitive price
Initial activated temperature: normal temperature (higher temperature makes higher decomposition ratio); O3 removal capacity>3000mg waste O3 gas/g catalyst; O3 decomposition ratio>95%; service space velocity>10000h-1; after decomposition, O3 concentration ratio < 0.10 ppm
