光氧催化设备用来处理哪些物质?

来源:http://www.spormac.net/   发布时间:2019-03-15 15:18:38
uv光氧催化设备是一种经过光来停止工作的零件,与发起机的排气管分离经过氧化减少污染的排放,它们关于废气污染做了极大的奉献.不只如此,在其他方面还有很多的用途,或许有些人关于光氧催化器的理解少之又少,那么就带你们来理解一下uv光氧催化设备主要用于处置哪些物质.
  Ultraviolet photocatalyst is a part that stops working by light. It is separated from the exhaust pipe of the initiator and oxidized to reduce the emission of pollution. They have made great contributions to the exhaust gas pollution. Not only that, but there are many other uses. Perhaps some people have little understanding of the photocatalyst. So let's take you to understand the main uses of the UV photocatalyst. What substances do you put in?
  同时能够有效减少排气中的HC,CO.氧化催化器能够除去90%的SOF,从而使PM排放减少40%~50%.其对HC和CO的处置效率能够分别到达88%,68%.催化氧化技术对脱除柴油机排放微粒中的可溶性有机成分(SOF)具有良好的效果,即在柴油机排气系统增设催化转化器.
  At the same time, it can effectively reduce HC, CO. oxidation catalysts can remove 90% of SOF in exhaust gas, thus reducing PM emissions by 40%~50%. The efficiency of HC and CO disposal can reach 88% and 68% respectively. Catalytic oxidation technology has good effect on removing soluble organic components (SOF) from diesel particulates, that is, adding catalytic converters in diesel exhaust system.

  SOF在铂、铑和钯等贵金属催化剂或稀土催化剂等的作用下发作氧化反响转化为CO2和H2O而除去,通常其脱除效率可达80%.同时还可除去尾气中的HC和CO等有害物质.但该技术脱除碳颗粒物的效果比拟差,并且催化剂有将排气中的SO2催化转化为SO3.
  SOF can be removed by oxidation reaction of noble metal catalysts such as platinum, rhodium and palladium or rare earth catalysts. Usually, the removal efficiency of SOF can reach 80%. At the same time, harmful substances such as HC and CO in tail gas can be removed. However, the removal efficiency of carbon particulate matter by this technology is poor, and the catalyst can convert SO2 in exhaust gas into SO3.
  而生成硫酸盐颗粒的趋向,特别是温度较高时硫酸盐生成速率增大,从而使颗粒物排放总量减少甚微.并且硫化物的存在还易使催化剂中毒劣化.所以柴油机颗粒催化氧化技术普通适用于含硫量较低的柴油燃料.
  The tendency of sulfate particle formation, especially at higher temperature, increases the rate of sulfate formation, which makes the total amount of particulate matter emission decrease slightly. Moreover, the presence of sulfide also makes catalyst poisoning deteriorate. Therefore, diesel particulate catalytic oxidation technology is generally applicable to diesel fuels with lower sulfur content.
