Main components: DMF, benzene, organic amines, ethyl acetate, methylene chloride, acetone, methanol, ethanol, butanone, ethyl ether, dichloroethane, acetic acid, chloroform and so on.
Main source: In the production process, pharmaceutical companies will use some organic solvents with low melting point and good volatility. Such solvents are likely to volatilize with the production process and lead to pollution, and their emissions mainly occur in the feeding, reaction, solvent recovery, filtration, centrifugation, drying, discharging and other operating units.
The main hazards: in the pharmaceutical industry in large quantities of organic solvents, volatile formation of irritating odors and malodorous gases, and has a certain degree of toxicity, the staff of the pharmaceutical plant and the nearby air caused by a great deal of impact, long-term emissions will also be on the human respiratory tract and the lungs to cause permanent damage, or coughing, and bronchitis, and so on.

Activated carbon adsorption device
Activated carbon adsorption: This technology can efficiently absorb benzene, alcohol, ketone, ester, gasoline and other organic waste gas, suitable for large air volume and low concentration of waste gas treatment. The method is to use the activated carbon itself high strength adsorption, combined with the role of the fan will be organic waste gas molecules adsorbed, benzene, alcohol, ketones, esters, gasoline and other organic solvents have a very good adsorption effect of exhaust gas.
Applicable concentration: 0-300 mg/m3
Applicable air volume: 1000-100000 m3/h
Processing efficiency: 80-90%
Performance characteristics:
1. Adsorption efficiency of up to 90%, large adsorption capacity, wide range of applications;
2. Convenient maintenance, no need for excessive human Easy maintenance, no need for too much manpower;
3. Large specific surface area, good selective adsorption, can simultaneously deal with a variety of mixed exhaust gas;
4. Activated carbon has a wide range of sources of inexpensive and other characteristics;
5. Simple and safe operation.
Scrubbing tower
Scrubbing tower: generally use gas-liquid countercurrent operation, the fan group will collect the exhaust gas suction to the exhaust gas absorption scrubbing purification tower, through the packing layer, the exhaust gas and the absorbing liquid gas-liquid two-phase full contact absorption and neutralization reaction, the exhaust gas is purified, and then through the mist elimination plate dehydration and mist removal by the fan discharged into the atmosphere. The absorbing liquid is pressurized at the bottom of the tower by the pump and sprayed down at the top of the tower, and finally flows back to the bottom of the tower for recycling.
Applicable air volume: ≤100000m3/h
Processing efficiency: 85-99%
Performance characteristics:
1. Adopting packing tower to purify the exhaust gas, which is suitable for the treatment of continuous and intermittent emission of exhaust gases;
2. Simple process, easy to manage, convenient operation and maintenance, will not cause any impact on the production of workshop;
2. It can purify many kinds of pollutants at the same time;
4. It has low pressure drop, big operation flexibility and good mist removal performance;
5. The tower body can be made of PP/glass fiber reinforced plastic according to the actual situation;
6. The packing adopts high-efficiency and low-resistance Bauer ring, which can remove the odor and harmful substances in the gas thoroughly. Odor, harmful substances, etc.;
7. Industrial waste gas treatment is well-designed, layer by layer purification and filtration of waste gas, the effect is better, the removal rate can be up to 99% or more.
