Honeycomb zeolite molecular sieve What waste gas can be treated? That's a lot.
1. The main components of spray paint exhaust are acetone, toluene, butanol, toluene, ethyl acetate and other volatile organic compounds. This kind of waste gas mainly exists in industries requiring painting. For paint spraying waste gas, according to its characteristics of large air volume and low concentration, the commonly used organic waste gas treatment method is molecular sieve fluid+regenerative incineration technology.
2. The main reason for plastic waste gas is that the polymer monomer is evaporated by particles such as plastic during heating. Due to the complex composition of plastics, there are many components in the exhaust gas, but the concentration is usually very low and the wind is strong. For this type of waste gas, the organic waste gas is usually treated by a more complex pretreatment process.
3. Chemical organic waste gas Some chemical enterprises produce some industrial waste gas according to production needs. The composition of waste gas is closely related to the type of chemical products designed and produced by enterprises. Generally, chemical enterprises usually use condensation recovery method and catalytic combustion method to purify and recover chemical organic waste gas when dealing with organic waste gas.
4. Pharmaceutical waste gas The waste gas of the pharmaceutical industry is complex, the product process is different, and there are different conditions for the same product. A better way is to design a targeted waste gas treatment scheme according to the current situation, to ensure that the exhaust gas emissions meet the standards.
5. The packaging and printing of waste gas after printing, as well as the use of a large number of solvent raw materials and auxiliary materials in the pre printing and printing process, such as the volatilization of ink solvent in the preparation process, the volatilization of printing ink solvent, the drying phase, and the composite technology and equipment in the cleaning process, including oil ink, education plate fluids, cleaning agents, adhesives, coating solutions, Diluent and other organic solvents. Benzene solvent is widely used in domestic packaging and printing industry. In addition to the above emissions from paint spraying, plastic, chemical, pharmaceutical, packaging and printing industries, organic emissions also include emissions from chemical fiber industries, rubber tires and other industries. The causes and components of these organic waste gases are different, and the treatment of organic waste gases is also different. Therefore, in practice, measures should be taken according to local conditions to ensure the improvement of economic benefits of enterprises and environmental benefits.
