Photo-Catalytic Oxidation Cabinet System Introduction:
Photochemical oxidation technology uses light-induced oxidation to combine O2, H2O2 and other oxidants with light radiation. The light used is mainly ultraviolet light, including uv-H2O2, uv-O2 and other processes, which can be used to treat difficult-to-degrade substances such as VOCs and malodors. In addition, in a system with ultraviolet light, there is a synergistic effect between ultraviolet light and iron ions, which greatly accelerates the rate of decomposition of H2O2 to produce hydroxyl radicals, and promotes the oxidation and removal of organic matter. The so-called photochemical reaction is a chemical reaction that can only proceed under the action of light. In this reaction, molecules absorb light energy and are excited to a high-energy state, and then electronically excited molecules undergo chemical reactions. Photochemical oxidation reduction uses n-type semiconductors as catalysts. TiO2 is very stable due to its chemical and photochemical properties, has the strongest light absorption rate, is non-toxic and cheap, and has sufficient supply. Therefore, photocatalytic redox removal of pollutants usually uses TiO2 as light. catalyst. The redox mechanism of the photocatalyst is mainly that the catalyst is irradiated by light, absorbs light energy, undergoes electronic transitions, generates "electron-hole" pairs, directly redox the pollutants adsorbed on the surface, or oxidize the hydroxyl OH- adsorbed on the surface, Generate strong oxidizing hydroxyl radical OH to oxidize pollutants. Schematic diagram of photo-oxygen catalysis 500.jpg Overview of the project site Source of exhaust gas Automobile coating is the link that produces the most "three wastes" in the automobile manufacturing process, and the exhaust gas from coating is the main part of the "three wastes" of coating. Due to people's inadequate understanding of the hazards of waste gas, insufficient waste gas treatment technology, and high waste gas treatment costs, coating waste gas is often discharged directly without treatment. These waste gases are discharged into the atmosphere without treatment, and under certain conditions will form photochemical pollution, affect the air quality, affect the growth of animals and plants and human health. Certain toxic VOC exhaust gases have disabling, teratogenic, and carcinogenic effects, and cause serious harm to human bodies exposed to them for a long time. To this end, various countries have issued corresponding laws and regulations to limit the emission of such gases. The GB16297 "Comprehensive Emission Standard for Air Pollution" promulgated and implemented by China in 1997 restricted the emission limits of 33 pollutants, including benzene and toluene. , Xylene and other volatile organic solvents (VOC) spraying process includes spraying, leveling and drying, each process has VOC emissions. In an automobile spraying metal workshop base paint, the VOC production in the spray booth, leveling room and drying room were 60%, 35%, and 5%, respectively, and the overcoat in the three processes were 50%, 20% and 30%. The main pollutants in the spray booth or spraying process are VOC and paint mist (particulate matter), and the main pollutants in the leveling and drying process are VOC. Paint mist particles are small (mostly below 10μm), high viscosity, easy to adhere to the surface of the material, before purifying organic waste gas The paint mist must be removed, and then toluene and xylene in the exhaust gas are further removed. In order to maintain the working environment of spraying, according to the provisions of the Labor Safety and Health Law, during the spraying operation, the spraying room should be continuously ventilated, and the ventilating speed should be controlled at (0.25 ~1) Within the range of m/s. The main composition of the exhaust gas from the paint spray booth is the organic solvent volatilized by the spray paint, and its main components are aromatic hydrocarbons, alcohol ethers, and ester organic solvents. Due to the large exhaust volume of the paint spray booth, the total organic waste gas exhausted The concentration is very low, usually below 100mg/m3. In addition, the exhaust of paint spray booths often contains a small amount of untreated paint mist, especially in dry paint mist capture spray booths. There is a lot of paint mist in the exhaust, which may become an obstacle to exhaust gas treatment. It must be pre-treated before exhaust gas treatment. deal with.
