UV光解空气净化器特点
UV光解空气净化器结构特点：
UV光解空气净化器采用组合式结构设计，低风阻≤400Pa,无噪音，无需专人管理，操作简单；主要组件可方便拆装维修或更换，净化效率可达≥90%。
1.前置过滤棉：具防火隔尘，有效隔离过滤体积稍大的杂物；
2.紫外光灯管：高能紫外线光束，去除有机臭味废气；每支灯管均为150W，灯管正常寿命为8000-12000小时；
3.电箱开关门：内有UV灯管控制开关，方便检修电源及光管等组件；
4.等离子体：依废气特性及性质，配置脉冲高频高压等离子降解污染物（属选配）；
5.活性碳层：依要求出口端可增活性碳吸附层（属选配）。
UV高效光氧废气净化器采用的大功率高能紫外线放电管，属低压水银放电管，发出的紫外线波长主要为170nm及184.9nm（目前正在研究开发150nm到184.9nm波长系列产品），光子能量分别为742 KJ/mol和647 KJ/mol。要裂解切断污染物质分子的分子键，就要使用发出比污染物质分子的结合能强的光子能。大多数化学物质的分子结合能比170nm及184.9nm波长紫外线的光子能量低，所以，本UV高效光解净化器能分解除碳，钙，金属外的大多数化学物质。
光解分解废气分子：首先废气经过253.7纳米波段光切割、断链、燃烧、裂解废气分子链，改变分子结构，取185纳米波段光对废气分子进行催化氧化，使破坏后的分子或中子、原子以O3进行结合，使有机或无机高分子恶臭化合物分子链，在催化氧化过程中，转变成低分子化合物CO2、H2O等，再根据不同的废气成分配置27种以上相对应的惰性催化剂，催化剂采用蜂窝状金属网孔作为载体，全方位与光源接触，惰性催化剂在338纳米光源以下发生催化反应，放大10-30倍光源效果，使其与废气进行充分反应，缩短废气与光源接触时间，从而提高废气净化效率。通过UV光解后的废气净化效果超过国家GB14554-93《恶臭污染物排放标准》表2恶臭污染物排放标准值，接着经过光解处理后的废气进入活性炭吸附箱。
UV光解净化器反应工程式：
1、UV + 高分子有机物→低分子有机物
2、UV + 空气( O2) →O3
3、低分子有机物+ O3→ CO2+ H2O +N2
Structure characteristics of UV photolysis air purifier:
Uv photolysis air purifier adopts a combination structure design, low wind resistance ≤ 400 pa, no noise, no special personnel management, simple operation; The main components can be easily disassembled and repaired or replaced, the purification efficiency can be up to 90 %.
1. pre - filter media: with fire proof dust, effectively isolate and filter the sundries with slightly larger volume;
2. ultraviolet lamp tube: high energy ultraviolet ray beam, remove organic odor and waste gas; Each lamp is 150 w, the normal life of the lamp is 8000 - 12000 hours;
3. electric box switch door: there is a UV lamp control switch, convenient maintenance of the power supply and light pipe components;
4. plasma: according to the characteristics and properties of the exhaust gas, the pulse high frequency high pressure plasma degradation pollutant ( optional ) is configured;
5. activated carbon layer: the outlet end of the activated carbon can be added to the activated carbon adsorption layer ( optional ).
The high - power high - power ultraviolet discharge tube used by UV - efficient light - oxygen converter belongs to low-voltage mercury discharge tube, the UV wavelength is 170n m and 184.9-187.5 nm ( currently being developed 150 nm to 184.9-187.5 nm wavelength series products ), the photon energy is 742 kj / mol and 647 kj / mol respectively. Cracking down on the molecular bonds of polluting substances requires the use of photons that are stronger than those of polluting the molecules. Most of the chemical molecules bind to photons with a lower photon energy than 170n m and 184.9-187.5 nm, so this UV - efficient photolysis purifier can dissolve most of the chemicals in carbon, calcium, and metal.
Photolysis of waste gas: first waste gas through 253.7 nm wavelength of light cutting, chain breaking, burning, cracking waste gas molecular chain, to change molecular structure of the molecular structure of the molecule or neutron and atom to O3 process the molecular chain of the organic or inorganic polymer odor compounds in the catalytic oxidation process to low molecular compound CO2 and H2O, and according to the different waste gas components of the corresponding inert catalyst, the catalyst uses honeycomb metal mesh hole as the carrier in all aspects of the light source of the inert catalyst under the 338 nano light source of the following catalytic reaction to enlarge the 10 - 30 times light source effect The exhaust gas purification effect after UV irradiation exceeds the emission standard value of odor pollutants in table 2 of the national GB 14554 - 93 " emission standard for odor pollutants ", and then the waste gas after photolysis treatment enters the activated carbon adsorption tank.
Uv photolysis purifier reaction engineering:
1. UV + polymer organic matter → low molecular organic matter
2. UV + air ( O2 ) → O3
3. low molecular organic matter + O3 → CO2 + H2O + N2 |
