臭氧分解催化劑
1.工作原理及流程Operation and Process
臭氧(O3)是氧的同素異形體,它是一種具有特殊氣味的淡藍色氣體。臭氧是一種強氧化劑,它在水中的氧化還原電位為2.07V,僅次于氟(2.5V),其氧化能力高于氯(1.36V)和二氧化氯(1.5V),能破壞分解細菌的細胞壁,很快地擴散透進細胞內,氧化分解細菌內部氧化葡萄糖所必須的葡萄糖氧化酶等,也可以直接與細菌、病毒發生作用,破壞細胞、核糖核酸(RNA),分解脫氧核糖核酸(DNA)、RNA、蛋白質、脂質類和多糖等大分子聚合物,使細菌的代謝和繁殖過程遭到破壞。可見,臭氧濃度過高對環境及人體健康有很大影響,而高濃度臭氧的魚腥味也讓人們難以忍受。
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
通常干燥空氣或干燥氧氣作通過放電后會產生臭氧。如大量復印機、印刷機、傳真機等機器,以及吸塵器、空氣清潔器的使用,通過電暈放電而產生臭氧;此外,臭氧殺菌消毒領域在殺菌后會殘留高濃度臭氧。
臭氧分解催化劑可以加速臭氧快速分解為氧氣,從而減小臭氧的危害性。
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.
含臭氧廢氣經干燥器(內放置分子篩、硅膠等干燥劑)除濕后進入催化反應器,催化處理干凈后排空。淀粉碘化鉀溶液不變色則為臭氧完全凈化。
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.工藝特點Operation Properties
技術特點為:① 分解能力強;② 耐濕性能強,可在相對濕度90%的高濕度條件下反應;③分解后臭氧濃度低。
采用型臭氧分解催化劑可快速使臭氧發生分解,使用溫度僅為室溫(當然溫度越高分解越快);催化劑除O3能力>3000mg O3廢氣/g催化劑;臭氧分解效率:>95%;使用空速:>10000h-1;經催化劑分解后臭氧的濃度小于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
