UV光解设主体设备配置带来哪些优势?

来源:http://www.spormac.net/   发布时间:2018-07-07 16:18:13
除能力不同UV光解设备是光束裂解恶臭气体中细菌的分子键,破坏细菌的核酸,再通过臭氧进行氧化反应,彻底达到脱臭及杀灭细菌的目的.设备特点:
The UV photolysis equipment is the molecular key of the bacteria in the odor gas, which destroys the nucleic acid of the bacteria and reacts through the ozone to achieve the purpose of deodorizing and killing bacteria.
1)、产品实用性广,可对多种混合酸气、臭气进行净化,可适应各类废气处理;
1), the product has wide practicability, and can purify various mixed acids and odors, which can be adapted to various kinds of waste gas treatment.
2)、产品采用多项醉先进的技术对废气进行多程处理净化,达到排放标准;
2), the product uses a number of advanced technology to clean up the exhaust gas and achieve emission standards.
3)、产品通过中央集中控制,自动化程度高,无须专人职守。
3), through centralized centralized control, the product is highly automated and requires no special duties.
1、恶臭物质能否被裂解,取决于其化学键键能是否比所提供的UV光子的能量要低。
1, whether or not the odorous substances can be lysed depends on whether their chemical bond energy is lower than the energy provided by the UV photons.
2、提供的UV光子总功率不够或者含氧量不足,会因为裂解或氧化不完全而生成一些中间副产物,从而影响净化效率。对于高浓度大分子的有机恶臭物质体现得较为明显。
2. The total power of the UV photon is not enough or the oxygen content is insufficient, and some intermediate by-products will be generated because of fragmentation or incomplete oxidation, which will affect the efficiency of purification. The organic odorous substances of high concentration of macromolecules are more obvious.
3、裂解反应的时间极短(<0.01s),氧化反应的时间需2-3s。

3, the reaction time is very short (< 0.01s), and the time of oxidation reaction is 2-3s.
4、为保证UV光解净化的长期稳定、高效,需要反应温度<70℃,粉尘量<100mg/m3,相对湿度<99%。
4, in order to ensure the long-term stability and efficiency of UV photolysis and purification, the reaction temperature is below 70 C, the dust content is less than 100mg/m3, and the relative humidity is less than 99%.
5、条件满足的情况下,UV光解设备废气净化器的醉高净化效率可达到99.9%以上。
5. Under the condition of satisfying conditions, the efficiency of the UV photolysis equipment exhaust purifier can reach over 99.9%.
对于某些有机化合物的部分化学键键能高于所提供的UV光子能量,如甲醛的“C=O”键的键能为728kj/mol。目前我们所提供的UV光子的能量为704kj/mol(正在研发742kj/mol和800kj/mol)。甲醛在170nm的UV紫外光的照射下,会裂解生成游离态的[C=O]*、H*。一部分[C=O]*与臭氧反应生成二氧化碳,一部分[C=O]*在经过与氮气等惰性物质碰撞后失去能量,生成一氧化碳,臭氧量充足时可将部分CO氧化成CO2
For some organic compounds, the bond number of some chemical bonds is higher than that of the UV photon energy provided, for example, the bond energy of the "C=O" bond of formaldehyde is 728kj/mol. At present, the energy of UV photons we provide is 704kj/mol (742kj/mol and 800kj/mol are being developed). Under the irradiation of UV ultraviolet light of 170nm, formaldehyde will dissociate into free [C=O]* and H*. Some [C=O]* reacts with ozone to produce carbon dioxide. Part of the [C=O]* loses energy after collisions with nitrogen and other inert substances and generates carbon monoxide. When the amount of ozone is sufficient, part of the CO can be oxidized to CO2.
如果提供的UV紫外线波长为160nm(742kj/mol),则反应过程相对就更加简单一些:甲醛会被直接裂解成游离态的C*、H*,会被臭氧直接氧化成二氧化碳和水。
If the UV UV wavelength is 160nm (742kj/mol), the reaction process is relatively simpler: formaldehyde will be directly cracked into free C*, H*, and will be directly oxidized to carbon dioxide and water by ozone.
