Many people in the paint room are not very strange, its work attention is car, machinery, hardware, furniture, glass steel products, chemical equipment. There is a lot of exhaust pollution in the process of use, so we need to deal with the exhaust gas in the paint room, but many people know how to do it. Today, Xiaobian will take a look at the exhaust treatment plan of the paint room and the precautions for the waste treatment of the paint room!
Paint room exhaust treatment plan
For the treatment of the exhaust gas in the paint booth, since there are particles such as paint mist that easily damage the equipment, before the VOCs mixed exhaust gas is treated, the exhaust gas is first subjected to operations such as paint mist and dust. In general, the VOCs mixed gas is mostly washed by a front spray tower.
Working principle of spray tower: The mixed exhaust gas is introduced into the purification tower by the air duct. After the filler layer, the exhaust gas and the absorption liquid are fully contacted and absorbed or chemically reacted to achieve the purpose of purification. After the exhaust gas is purified, it is dehydrated by a defogging plate.
Photocatalytic oxidation: Photocatalytic oxidation is catalyzed by external visible light. Photocatalytic oxidation is a catalyst for semiconductors and air. The light is used as energy to degrade organic matter into CO2 and H2O.
Heterogeneous catalytic oxidation: a collection of exhaust gas treatment technologies such as photocatalytic oxidation, UV photon photolysis, and advanced oxidants. The treatment efficiency of the organic matter can be improved, and the technology can be reacted at normal temperature and pressure, the operation cost is low, the equipment has a small footprint, and the safety performance is high.
Plasma catalytic oxidation: The organic exhaust gas is activated by plasma excitation and dissociation, and then the activated exhaust gas is subjected to catalytic oxidation reaction with oxygen in the exhaust gas through high-energy rays on the surface of the rare metal oxide, and finally converted into carbon dioxide and water.
RTO regenerative combustion: The regenerative combustion method is to completely oxidize organic molecules into carbon dioxide and water in a high temperature environment to achieve standard discharge, which has high purification efficiency.
As one of the main sources of atmospheric pollution, VOCs are not only one of the main substances forming PM2.5, but also an important precursor of ozone formation in the near-surface layer. Some environmental experts said that to solve ozone pollution, the problem of VOCs should be solved first. Therefore, the problem of VOCs has become an environmental protection issue that is urgently needed to be solved. In addition to the installation of end-of-pipe facilities and corresponding monitoring equipment for enterprises that require VOCs, the use of raw materials should be as close as possible to clean and environmentally friendly materials to reduce VOCs emissions from the source.
Precautions for the exhaust gas treatment and purification equipment of the paint room:
1. Before use, check whether the pipeline valves of each system of the equipment are in good condition, and whether the selection and ratio of the absorbent liquid are correct.
2, the exhaust fan treatment and purification of the fan and pump wiring can not be arbitrarily moved, should be absolutely guaranteed that their steering is correct.
3. After the exhaust gas purification treatment equipment is delivered and delivered, the use unit shall send a special person to keep it for use and check it regularly.
4. The exhaust gas purification treatment equipment is installed outdoors, and the water pump fan motor should be made of rain cover to avoid the motor being damp. The replacement ratio of the exhaust gas purifying solution and the formulation ratio of the purifying and absorbing liquid are determined according to the different gas sources of the user unit and the concentration.
The above is the introduction of the paint room waste treatment plan and the waste gas treatment precautions for the paint room in Xiaobian today. I believe that through the introduction today, everyone has a new idea about the waste gas treatment in the paint room. For more information, please stay tuned to the renovation home.
