UV photooxygen purification technology works
Utilizing a special high-energy high-ozone UV light beam to irradiate organic gases and oxygen molecules in the air, to break the molecular bonds of organic gases, and to decompose oxygen molecules in the air to generate free oxygen, namely active oxygen, UV + O2 → O- + O * active oxygen O + O2 → O3 ozone. The pollutant molecules in the free state are combined with ozone oxidation to form small molecule harmless or low-toxic compounds, such as CO2, H2O, etc. So as to achieve the effect of purifying the gas. Purification ability can reach 99%.
Reaction engineering formula: 1. UV + polymer organic matter → low molecular organic matter
2.UV + air O2 → O3
3.Low molecular organic matter + O3 → CO2 + H2O + N2
UV Photooxygen Purifier Technology Support
The high-power and high-energy ultraviolet discharge tube used in this UV photolysis purifier is a low-pressure mercury discharge tube. The ultraviolet wavelengths emitted are mainly 170nm and 184.9nm (currently developing 150nm to 184.9nm wavelength series products) and the photon energy is 742 KJ / mol and 647 KJ / mol. To break the molecular bonds of pollutant molecules, it is necessary to use photon energy that is stronger than the binding energy of pollutant molecules. Table 1 lists the binding energies of the main chemical molecules. As can be seen from Table 1, the molecular binding energy of most chemical substances is lower than the photon energy of 170nm and 184.9nm ultraviolet rays. Therefore, this UV photolysis purifier can separate most chemical substances except carbon, calcium and metals.

Exhaust gas treatment standards:
The exhaust gas treated by the above UV / O3 high-energy photolysis exhaust gas purification equipment can meet the requirements of the "Integrated Emission Standard for Air Pollutants" (GB16297-1996) and the "Emission Standard for Odor Pollutants" (GB14554-1993).
UV photolysis purification technology, to a degree, simulates the decomposition mechanism of ultraviolet light in the sun to purify the decomposition mechanism of exhaust gas. Through technical methods, the decomposition energy and process of ultraviolet decomposition of exhaust gas are artificially controlled, and the release of ultraviolet energy is enhanced in a short time. This speed of decomposition and oxidation is accelerated to achieve the purpose of "exchanging energy for time". Whether the malodorous substance can be cracked depends on whether its chemical bond energy is lower than the energy of the provided UV photons. The cracking reaction time is short (<0.01s), and the oxidation reaction time is 2-3s. Insufficient total UV photon power or insufficient oxygen content will generate some intermediate by-products due to incomplete cracking or oxidation, thereby affecting purification efficiency. It is more obvious for high-concentration macromolecular organic malodorous substances. The long-term stability of the photocatalytic oxidation deodorization equipment requires a reaction temperature of <70 ° C, a dust volume of <100mg / m3, and a relative humidity of <99%. When the conditions are satisfied, the high purification efficiency of the photocatalytic oxidation deodorization equipment can reach more than 95%.
