Paint spraying exhaust gas, mainly consists of 2 parts, one is liquid paint mist, and the other is gaseous VOC. for liquid paint mist, the use of spraying and other wet methods of dust removal, both have a certain effect (paint into the body of water to be considered after the wastewater treatment) at present, no pumps water curtain spraying cabinets on the treatment of paint mist can reach 98%; but for the insoluble VOC, you can use the " Activated carbon adsorption + catalytic combustion". Activated carbon gas odor absorption, UV photolysis purifier of ultraviolet light on the exhaust gas catalytic combustion effect.
The working principle of UV photolysis purifier
This product uses special high-energy, high-ozone UV beam to irradiate the exhaust gas, cracking the molecular chain of industrial waste gas such as: ammonia, trimethylamine, hydrogen sulfide, hydrogen methyl sulfide, methyl mercaptan, methyl sulfide, butyl acetate, ethyl acetate, dimethyl disulfide, carbon disulfide, and styrene; sulfide H2S, VOCs; benzene, toluene, and xylene. Structure, so that organic or inorganic polymer malodor compounds molecular chain, in the high-energy ultraviolet beam irradiation, degradation into low molecular compounds, such as CO2, H2O. 2. Using high energy and high ozone UV beams to decompose oxygen molecules in the air to produce free oxygen, i.e., activated oxygen, because of the imbalance of positive and negative electrons carried by the free oxygen so need to be combined with oxygen molecules, which in turn produces ozone.
UV + O2 → O- + O * (active oxygen) O + O2 → O3 (ozone)?
3. Using high-energy UV beams and ozone to carry out synergistic decomposition and oxidation reaction on industrial waste gas, the industrial waste gas material is degraded and transformed into low molecular compounds, water and carbon dioxide, using high-energy UV beams to crack the molecular bonds of bacteria in industrial waste gas, destroying the nucleic acid (DNA) of bacteria, and then oxidizing the reaction through ozone, to completely achieve the purpose of purification and killing of bacteria.
(Note: The material of this product can be 1.5 thick spray galvanized sheet, 201 stainless steel and 304 stainless steel. Because of the strong oxidizing effect of ozone itself, stainless steel is the preferred material.)
