Source of pesticide exhaust gas
① Reactor feeding port. Due to the exothermic synthesis reaction of pesticides, the foul odor generated during the reaction process is emitted through the feeding gate, and the odor is very strong.
② The discharge port of the reaction kettle and the solvent outlet of the closed centrifuge.
③ A product that has undergone initial desolvation Use an outdoor drying pool for drying, or use a drying room for drying. Although the concentration of odorous substances emitted by the product during the drying process is relatively low, the total amount of odorous substances emitted is large due to the large surface area of the raw material. Due to the small diffusion and dilution ability of the ground, it has a significant impact on the surrounding environment.
The exhaust gas mainly consists of acid gas and alkali gas, as well as VOCS gases such as benzene, toluene, ethanol, methanol, cyclohexane, aniline, etc. Methods for purifying odors
Collect all exhaust gas through branch pipes and gradually merge them into the main pipe according to the composition of the exhaust gas
Select equipment based on the characteristics of the process, typically with exhaust gas concentrations ranging from tens to thousands of milligrams per cubic meter.
Sulfur containing compounds: such as H2S, NH3, thiols, etc; Chlorine containing compounds: chloroform, dichloroethane, etc;
Method for purifying odor system in pesticide factory:
PP tower washing+activated carbon adsorption+desorption thermal oxidation
1. PP tower washing+UV photocatalytic oxidation.
2. PP tower washing+low-temperature plasma oxidation
3. PP tower washing+activated carbon adsorption+desorption thermal oxidation
4. PP tower washing+zeolite wheel concentration oxidation
