320w UVC Light With Ballast High Temperature Working Environment G13

Kitchen fume purification
The ultraviolet light that generates ozone can be used in the oil fume purification equipment. The ultraviolet light coolly produces trace powder, carbon dioxide and water from the oil molecules. The organic matter in the oil fume is photolyzed and oxidized, and the peculiar smell in the flue also disappears. In addition, there is no oil dirt in the oil smoke exhaust pipe, which greatly eliminates the fire hazard and has an immediate effect on the removal of odor.

 

Use high-energy ultraviolet light with a wavelength of 185nm to break molecular bonds

 

The binding energy of some chemical molecular bonds

 

The photon energy of ultraviolet light with a wavelength of 185nm is as high as 647KJ/mol, and the molecular binding energy of most chemical substances is lower than that of the wavelength of 185nm. Therefore, the molecular bonds of pollutants can be broken by the cracking of 185 high-energy ultraviolet light energy, and most organic waste gases. It is C, H, O structure, and the chemical bond is less than 185NM ultraviolet energy, so these organic waste gases can be decomposed into CO2 and H02 in the presence of O2.

 

But it is worth noting that the 185nm wavelength ultraviolet rays are vacuum ultraviolet rays, which combine with O2 to produce O3 as soon as they come out of the lamp tube, so their ""range"" is extremely short, and basically there is a small amount of intensity on or near the surface of the lamp tube, so it can The organic waste gas treated by 185NM wavelength ultraviolet rays breaking the bond is basically a part that can be in contact with the surface of the lamp tube or close to the lamp tube.

 

Example: The photolysis mechanism of benzene molecule:

 

Molecular structure and molecular bond energy of benzene:

 

Benzene is made up of hydrogen atoms (1s1) and carbon atoms (1s22s22px12py1)

 

Benzene (C6H6) is an organic compound with the simplest composition of aromatic hydrocarbons. It is a colorless, sweet and transparent liquid at room temperature and has a strong aromatic odor. Benzene is flammable, toxic, and is an IARC Group I carcinogen. Benzene is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. Benzene has a ring system called the benzene ring, which is the simplest aromatic ring. The structure of benzene molecule after removing one hydrogen is called phenyl, which is represented by Ph. Therefore benzene can also be expressed as PhH.

According to the structural characteristics of benzene, it is not difficult to understand that when the UV photon energy is greater than 611kJ/mol (take the maximum bond energy value), the benzene ring will be broken, forming an ionic C-C+C-C+C-C+ and H-H+H-H+H-H+, which respectively react with ozone after the molecular bond is broken. Benzene molecule (C6H6) is finally cracked and oxidized into CO2 and H2O." The main principle of UV photolysis waste gas method is to decompose waste gas molecules through high-energy UV ultraviolet rays, and quickly oxidize harmless substances, so as to achieve the purpose of purification. In addition, different treatment tops can be designed according to different emissions, so as to avoid waste of resources, and adopt the most suitable treatment equipment according to the current status of exhaust emissions of enterprises. Moreover, UV photolysis waste gas treatment is not affected by the outside world, such as temperature, air humidity, wind direction, etc., only need to control the switch of the equipment, almost no need to be guarded, the equipment runs stably and reliably, and is suitable for most waste gas Treatment is the main method of waste gas treatment in my country.
