The working principle of the photo-oxygen catalytic purifier
Photocatalytic purification principle: Utilize high-ozone UV light beams (emission wavelengths are mainly 170nm and 184.9nm, energy is 742kj / mol and 647kj / mol) to irradiate malodorous gases, and decompose organic (odorous) waste gas such as ammonia, trimethylamine , Hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and styrene, VOCs, benzene, toluene, xylene and other molecular chain structures, making organic or inorganic polymer malodorous compound molecular chains Degradation and transformation into low molecular compounds, such as CO2, H20, etc. under the irradiation of ultraviolet beam. The high-ozone ultraviolet light beam decomposes oxygen molecules in the air to generate free oxygen, that is, active oxygen. Due to the imbalance of the positive and negative electrons carried by the free oxygen, it needs to combine with the oxygen molecules to generate ozone.
UV + O2 → O- + O * (active oxygen) O + O2 → O3 (ozone). It is well known that ozone has a strong oxidizing effect on organic matter, and has an immediate effect on malodorous gases and other irritating odors. The catalytic layers (catalyst: nano-titanium dioxide) on both sides of the lamp tube generate strong chemically active superoxide anion radicals and hydroxide radicals when they are irradiated by ultraviolet light, attacking organic matter and degrading organic matter. Titanium dioxide is a non-dissolvable material. While it decomposes and kills organic pollutants, it does not decompose or dissolve itself, has a long-lasting photocatalytic effect, and has a long-lasting sterilization and degradation effect of pollutants. After the malodorous gas is input to the purification equipment by the exhaust equipment, the purification equipment uses the ultraviolet beam and ozone to synergistically decompose and oxidize the malodorous gas, so that the malodorous gas substance is degraded and converted into low molecular compounds, water and carbon dioxide, and then passes through the exhaust duct Drain outdoors.
Low-temperature ion principle: The adsorption-decomposition-carbonization process technology design of the low-temperature plasma organic waste gas purification module adopts the advantages of standard module design and other advantages. It is a purification device for dry processing of organic and smoke exhaust gas. It changes the process technology of using activated carbon materials, no need to handle raw materials, no special person responsible, no secondary pollution, easy replacement and maintenance (the maintenance operation can be changed under normal operating conditions of the equipment).
