A, baking paint room exhaust gas treatment program
1, for the treatment of baking paint room exhaust gas, due to the presence of particles containing paint mist and other easy to damage the equipment, so in the VOCs mixture of exhaust gas before treatment, first of all, will be in addition to the paint mist, dust, and other operations on the exhaust gas. Generally speaking, most of the front spray tower is used to scrub the mixed VOCs gas.
2, spray tower working principle: mixed exhaust gas from the duct into the purification tower, through the packing layer, the exhaust gas and absorbent liquid for full contact absorption or chemical reaction, to achieve the purpose of purification. After the exhaust gas is purified, it is then dewatered and operated by the demisting plate.
3, photocatalytic oxidation: photocatalytic oxidation is catalytic under the action of external visible light, photocatalytic oxidation reaction is the semiconductor and air as a catalyst, with light as the energy, the degradation of organic matter into CO2 and H2O.
4, multi-phase catalytic oxidation: a collection of photocatalytic oxidation, UV photo-quantum photolysis, high-level oxidants, and other technologies of the exhaust gas treatment technology. It can improve the treatment efficiency of organic matter, and this technology can be reacted at room temperature and pressure, with low operating costs, small equipment footprint and high safety performance.
5, plasma catalytic oxidation: organic waste gas by plasma excitation, dissociation activation, and then activated waste gas by high-energy rays on the surface of rare metal oxides, and the oxygen in the waste gas catalytic oxidation reaction occurs, and ultimately converted into carbon dioxide and water and other substances.
6, RTO regenerative combustion: the use of regenerative combustion method is organic molecules in the high-temperature environment is completely oxidized into carbon dioxide and water, to achieve compliance with the emission standards, has a high purification efficiency. /7, VOCs as one of the main sources of air pollution at present, is not only the formation of PM2.5 is one of the main substances, or near-earth layer ozone generation is an important precursor. Some environmental experts said that to solve ozone pollution, the VOCs problem should be solved first. Therefore, the problem of VOCs has become an urgent environmental protection issue. In addition to requiring VOCs-generating enterprises to install end-of-pipe treatment facilities and corresponding monitoring equipment, the use of raw materials should try to choose clean and environmentally friendly raw materials to reduce the emission of VOCs from the source.
Second, the paint room exhaust treatment precautions:
1, before using the equipment should be checked whether the system piping valves are intact, the absorption liquid agent selection and proportioning is correct.
2, exhaust gas treatment and purification of the fan and pump wiring can not be randomly moved, should absolutely ensure that they are turned correctly.
3, exhaust gas purification and treatment equipment running after delivery, the use of units should be sent to keep people use, regular inspection.
4, exhaust gas purification and treatment equipment installed outdoors, the pump fan motor should be made rain cover, so as to avoid the motor moisture. Exhaust gas purification liquid replacement and dispensing of purification and absorption liquid formula ratio is based on the user unit of gas source different, high and low concentration to decide.
Today's content on the paint booth exhaust treatment program is introduced here for you, I hope you can use these programs in practice. In addition, we also need to grasp some of the paint booth exhaust gas treatment purification equipment, in the normal course of time should be sent to the custody of a person to regularly check the equipment.
