光氧催化除臭工艺的特点介绍

来源:http://www.spormac.net/   发布时间:2018-12-03 16:10:02
1、利用高能高臭氧紫外线光束分解空气中的氧分子产生游离氧,即活性氧,因游离氧所携正负电子不平衡所以需与氧分子结合,进而产生臭氧。UV+O2→O-+O*(活性氧)O+O2→O3(臭氧),众所周知臭氧对有机物具有极强的氧化作用,对有机气体及其它刺激性异味有立竿见影的清除效果。有机性气体利用排风设备输入到本净化设备后,运用高能紫外线光束及臭氧对有机(异味)气体进行协同分解氧化反应,使有机气体物质其降解转化成低分子化合物、水和二氧化碳,再通过排风管道排出室外。
1. The use of high-energy and high-ozone ultraviolet beam to decompose oxygen molecules in the air to produce free oxygen, i.e. reactive oxygen species, because of the positive and negative electron imbalance carried by free oxygen, it is necessary to combine with oxygen molecules to produce ozone. UV+O 2_O-+O* (reactive oxygen species) O+O 2_O 3 (ozone), it is well known that ozone has a strong oxidative effect on organic compounds, and has an immediate effect on the removal of organic gases and other irritating odors. After the organic gases are fed into the purification equipment by exhaust equipment, the high-energy ultraviolet light beam and ozone are used to decompose and oxidize the organic (odor) gases synergistically, so that the organic gases can be degraded into low-molecular-weight compounds, water and carbon dioxide, and then discharged outdoors through the exhaust duct.
2、高能离子空气净化系采用正负双极电离技术。在电场作用下,离子发生器产生大量的 a 粒子, a 粒子与空气中的氧分子进行碰撞而形成正负氧离子。正氧离子具有很强的氧化性,能在极短的时间内氧化分解甲硫醇、氨、硫化氢等污染因子,且在与 VOC 分子相接触后打开有机挥发性气体的化学键,经过一系列的反应后最终生成二氧化碳和水等稳定无害的小分子。同时氧离子能破坏空气中细菌的生存环境,降低室内细菌浓度。带电离子可以吸附大于自身重量几十倍的悬浮颗粒,靠自重沉降下来,从而清除空气中悬浮胶体达到净化空气的目的

2. High energy ion air purification system adopts positive and negative bipolar ionization technology. Under the action of electric field, the ion generator produces a large number of a particles, which collide with oxygen molecules in the air to form positive and negative oxygen ions. Positive oxygen ions are highly oxidizing, which can oxidize and decompose pollution factors such as methyl mercaptan, ammonia and hydrogen sulfide in a very short time, and open chemical bonds of organic volatile gases after contacting with VOC molecules. After a series of reactions, stable and harmless small molecules such as carbon dioxide and water are finally formed. At the same time, oxygen ions can destroy the living environment of bacteria in the air and reduce indoor bacterial concentration. Charged ions can absorb suspended particles which are tens of times larger than their own weight and settle down by self-weight, thus removing suspended colloids in the air to purify the air.
2、催化剂(二氧化钛)在受到紫外线光照射时生成化学活泼性很强的超氧化物阴离子自由基和氢氧自由基,攻击有机物,达到降解有机物的作用。二氧化钛属于非溶出型材料,在彻底分解有机污染物和杀灭菌的同时,自身不分解、不溶出,光催化作用持久,并具有持久的杀菌、降解污染物效果。
2. Catalysts (titanium dioxide) generate superoxide anion radicals and hydroxyl radicals with strong chemical activity when irradiated by ultraviolet light, which attack organic substances and degrade organic substances. Titanium dioxide is a kind of non-dissolvable material. It can completely decompose organic pollutants and sterilize them, but at the same time, it does not decompose and dissolve itself. Its photocatalytic activity lasts for a long time, and it has the effect of lasting sterilization and degradation of pollutants.
