Repair shop paint room exhaust gas treatment method analysis

For the repair shop paint booth paint booth exhaust treatment methods are many, such as adsorption, water spraying, condensation, catalytic combustion, direct combustion, catalytic oxidation, plasma method, etc., the specific choice of what exhaust treatment method needs to be based on the actual conditions to determine the following with the Everest blue editor to understand.

Repair shop paint booth paint booth exhaust type:

1, for oil-based paint: with paint particles of water beads water-based paint: dissolved paint particles of water beads.

2、Independent high flying paint particles in the exhaust gas.

3, the gasification of the paint itself raw material odour, paint thinner odor, and its reaction and curing.

Repair shop paint room paint room exhaust method:

Shower tower: Mixed exhaust gas is introduced into the exhaust gas purification equipment by the air duct, through the packing layer, the exhaust gas and the absorbing liquid to carry out full contact to the absorption or chemical changes, to achieve the purpose of purification and treatment. Exhaust gas through the purification treatment, and then dewatered by the de-misting plate for manipulation.

Low temperature plasma method:

Plasma internally generates particles containing very high chemical vitality, such as electrons, ions, free radicals and excited state molecules. The pollutants in the exhaust gas react with these energetic groups with high energy, and are eventually converted into carbon dioxide and water, thus achieving the purpose of purifying the exhaust gas. Wide range of applications, high purification efficiency, especially in the combined use of other methods can not be disposed of multi-component odour, industrial waste gas.

Photocatalytic reaction:

Photocatalytic reaction is a catalytic reaction under the action of external visible light, photocatalytic redox reaction is a semiconductor and air as a catalyst, with light as energy, decomposition of organic matter into CO2 and H2O.

Multiphase catalysis is oxidised:

Exhaust gas management technology that combines photocatalytic reaction, UV quantum photolysis, advanced oxides and other techniques. It can promote the treatment effect of organic matter, and such technology can carry out the reaction at room temperature and normal pressure, the operation cost is cheap, and the equipment occupies a smaller ground, and the safety is higher.

Low temperature plasma catalytic reaction:

Organic waste gas by low-temperature plasma excitation, ionisation activation, followed by activation of the waste gas by the higher energy rays in the surface layer of rare metal oxides, and the oxygen in the waste gas catalytic reaction reaction, thus converted to carbon dioxide and water and other substances.

RTO regenerative combustion:

Selected regenerative combustion method is organic molecules in the high-temperature premise is completely oxidised into carbon dioxide and water, to achieve environmental standards, with a high purification and treatment effect.
