A UV light, deodorizing purification equipment in general principle:
恶臭气体利用收集排风设备输入到UV光解除臭净化设备后，净化设备运用深圳海德隆高能UV紫外线光束、臭氧O3及纳米光催化TiO2等技术组合起来对废气进行协同分解氧化反应，使废气降解转化成无害无味化合物、水和二氧化碳，再通过排风管道排出。由于是在深圳海德隆高能UV光解灯的紫外光+臭氧+光触媒的综合光催化氧化反应下，净化废气除臭的过程中无任何添加剂，生成物也是CO2和H2O以及其它无毒无害物质，所以不会发生二次污染，运行成本方面仅仅用到电能，无需经常维护和更换。
Malodorous gases by collecting exhaust equipment input to UV light lift odor purification equipment, purification equipment using Shenzhen sea Delong high-energy UV ultraviolet light, ozone (O3) and nano photocatalytic TiO2 combination of CO oxidation reaction on the exhaust, the exhaust gas decomposition into harmless and tasteless compound, water and carbon dioxide, again through the exhaust air from the exhaust pipe. Because it is in the Shenzhen sea Delong high-energy UV photolysis lamp UV + O3 + photocatalyst comprehensive photocatalytic oxidation reaction, purifying exhaust gas deodorization process without any additives, product is CO2 and H2O and other innocuous substances, so there are no secondary pollution, transport costs only use electric energy and does not need regular maintenance and replacement.
二、UV光解除臭净化设备技术详解：
Two, UV light deodorizing purification equipment technology:
1、紫外光照射裂解技术：UV光解除臭净化设备利用特制的高能UV紫外线光束照射恶臭气体，裂解恶臭气体如：氨、三甲胺、硫化氢、甲硫氢、甲硫醇、甲硫醚、二甲二硫、二硫化碳和苯乙烯，硫化物H2S、VOCs类，苯、甲苯、二甲苯的分子链结构，使有机或无机高分子恶臭化合物分子链，在高能紫外线光束照射下，降解转变成低分子化合物，如CO2、H2O等。

2、臭氧氧化技术：利用高能高臭氧真空波UV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。
2, ozone oxidation technology: the use of high energy and high ozone vacuum wave UV light beam decomposition of oxygen molecules in the air to produce free oxygen, that is, reactive oxygen species, due to the free oxygen carrying electron positron imbalance so needs to combine with oxygen molecule and then generates ozone.
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，对恶臭气体及其它刺激性异味有立竿见影的清除效果。
O-+O* - O+O2 (active oxygen) UV+O2 - O3 (ozone), it is known that ozone has a strong oxidation of organic matter, the odor of gas and other irritating odor has an immediate effect on the removal of.
3、光触媒光催化技术：纳米光催化TiO2，其作用机理简单来说：纳米光催化剂TiO2在特定波长的光的照射下受激生成"电子一空穴"对(一种高能粒子)，这种"电子一空穴"对和周围的水、氧气发生作用后，就具有了极强的氧化-还原能力，能将空气中醛类、烃类等污染物直接分解成无害无味的物质，以及破坏细菌的细胞壁，杀灭细菌并分解其丝网菌体，从而达到了消除空气污染的目的。

三、DERON-UV高能UV光解灯介绍：
Three, DERON-UV high energy UV photolysis lamp introduction:
山西TT废气处理（深圳海德隆山西办）推出的UV光解除臭净化设备中所采用的DERON-UV真空波高能UV光解紫外灯由是美国进口原材料(高纯石英沙)和韩国技术制作的，具有高精度高透射率，肉眼直观即可看得到管体通体极为纯净透明，寿命10000h以上，通常如24小时使用的话，建议一年左右更换一次灯管;uv光解紫外灯所配套的镇流器也采用的是美国进口内芯，内置线路板上的元器件更多更复杂，拿起时手感厚重，质量比起国内同类产品要更好一点，能够适应复杂的废气处理环境，质保2年。另外配套有胶圈，方便灯头、灯尾在安装时起到固定和密封的作用。

In addition to supporting a rubber ring, convenient lamp, lamp tail plays a role in fixing and sealing installation.
四、光触媒技术与紫外线灯的作用原理
Principle four, photocatalyst technology with ultraviolet light
1、光触媒的有机污染物分解原理纳米级的TiO2在紫外光的照射下，由于吸收了光能而产生电子空穴对。这些空穴对(光载流子)会迅速迁移至表面，并激活其表面附着的H2O与O2而产生氢氧基(-OH)和活性氧(-O)。而这两种氧化性极强的物质会迅速与触媒表面附着的细菌、病毒及大分子量的碳氢化合物反应，生成无害的CO2和水。这一作用原理现正被广泛应用到废气净化和水消毒领域中。光触媒网与紫外线灯结合，可应用于鲜风或空调系统的净化、有机污染物VOCs废气及污水处理流程等。具有节能、长效、无二次污染的优点。
1, the photocatalyst of organic pollutants decomposition principle of nanometer TiO2 under UV irradiation, due to the absorption of light energy and electron hole pairs. The hole on the optical carrier will rapidly migrate to the surface, and activate the attached to the surface of H2O and O2 generated hydroxyl (- OH) and active oxygen (o). And the two strong oxidizing substances will rapidly with the catalyst surface attached bacteria, virus and high molecular weight hydrocarbons reaction, generate the harmless CO2 and water. This principle has been widely applied to the field of waste gas purification and water disinfection. Combined with photocatalyst and ultraviolet lamp, application in the fresh air of air conditioning system purification, organic VOCs waste gas and sewage treatment process etc.. The advantages of energy saving, long lasting, no two pollution.
2、光触媒的亲水自洁净原理如前我们讨论过光触媒在紫外光的作用下能有效地分解附着于上的污染物，而产生一个清洁的表面。同时生成的氢氧基(-OH)会与空气中的H2O结合而使触媒表面产生亲水性。而采用了这种技术的光触媒滤网，由于具有亲水性，在含水份的废气流冲击下，其表面的可能附着的粉尘等固态附着物能非常容易被清洗掉，而保持了光触媒滤网表面的清洁，节约了大量的人工清洁成本。这类附着于光触媒滤网的光触媒材料可利用光解设备中的紫外线成分进行工作。但它被激发时所需的紫外能量较高，因此必须采用高强度的紫外线灯管进行激发。
2, photocatalyst hydrophilic cleaning principle as we discussed photocatalyst under UV irradiation can effectively decompose the attachment on the pollutants, and produce a clean surface. At the same time, the generation of hydroxyl radical (-OH) combined with H2O in air and the hydrophilic surface of catalyst. And the use of the photocatalyst filter screen with this technique, due to its hydrophilicity, in containing moisture exhaust flow impact, the surface may be attached to dust and other solid attachment can is very easy to be cleaned, and maintains the photocatalyst filter surface clean, saving the cost of a large number of manual cleaning. This type of attachment to the photocatalyst filter material can work with photocatalyst ultraviolet component in photolysis equipment. But it is excited when the required UV energy is higher, so we must use high intensity ultraviolet lamp to stimulate.
3、光触媒技术原理及紫外线灯在此技术中的采用光触媒(photocatalyst)在英文中是由光(photo)及催化剂(catalyst)两个单词组合而成。其中的光指的是380mm波长以下的紫外光，尤以波长253.7nm即通常所说的254nm紫外灯发出的光波为佳。催化剂现今一般是指纳米级的TiO2材料，经过配方及技术处理，烧结附着于铝基蜂窝状滤网上，共用于废气处理净化设备里，称光催化氧化光解设备。光触媒中的TiO2在紫外线的照射下，自身不发生变化。但能产生出氧化力极强的氢氧基(-OH)与活性氧(-O)，将其周围的碳氢化合物分解为CO2和H2O。因而具有极强的杀菌，净化和自洁净功能，可达10年以上不需更换。
3, photocatalyst technology principle and ultraviolet lamp in this technology using photocatalyst (photocatalyst) in both English and Chinese is made of light (photo) and catalyst for the two word combinations. The light refers to the 380mm wavelength of UV light, especially at the wavelength of 253.7nm, which is commonly referred to as the 254nm ultraviolet light emitted by the light. Catalyst today is generally refers to the nanoscale TiO2 materials, after formulation and processing technology, sintering attached to aluminum based honeycomb filter net, common to the exhaust gas treatment purification equipment, the photocatalytic oxidation of photolysis equipment. The TiO2 photocatalyst under ultraviolet light, itself does not change. But it can produce strong oxidizing hydroxyl (-OH) and reactive oxygen species (-O), the hydrocarbons around the decomposition of CO2 and H2O. Therefore has the extremely strong sterilization, the purification and the self cleaning function, can reach 10 years above does not need to change.
