The paint spray booth activated carbon adsorption method adopts a new type of activated carbon, which has large specific surface area and porosity, strong adsorption capacity, good mechanical strength, chemical stability and thermal stability. If double-layer adsorption is adopted, the organic waste gas can be contacted with the activated carbon. , The organic pollutants in the exhaust gas are adsorbed on the surface of the activated carbon, so as to be separated from the airflow to achieve the purification effect.
Volatile organic waste gas in the spray booth: organic solvents, mainly triphenyl (benzene, toluene, xylene) are used to dilute the paint to achieve a smooth and beautiful surface, but organic solvents are very volatile and cannot be attached to the paint for a long time On the surface of the object, it will be completely released during the spraying and drying process to form organic waste gas. coal based active carbon It is characterized by colorless and extremely irritating. It diffuses in the atmosphere with the flow of air, and can breathe into the body or directly affect the human body , Causing damage to the human respiratory system, blood, heart and lungs, liver, mucous membranes, eyes, nerves, etc., and directly harming the human body through the skin.
What are the advantages of using activated carbon to adsorb paint spray booth exhaust gas:
1. The drag coefficient is small
This is a unique feature of activated carbon, because the exhaust gas adsorption activated carbon will not affect the passage rate of exhaust gas, and the service life of the adsorption equipment will not affect it, which is very in line with the gas flow.
2. Strong adsorption capacity
The unique structure of activated carbon that causes exhaust gas adsorption can make exhaust gas fully contact with activated carbon and increase its adsorption capacity. Moreover, the adsorption equipment used is small in size and convenient to replace, and the adsorbed gas can reach the emission standard.
3. The use of activated carbon has a small investment, saves costs, and the product is safe and reliable.
The paint spray booth activated carbon adsorption method adopts Hongyu's new activated carbon. The activated carbon has large specific surface area and porosity, strong adsorption capacity, good mechanical strength, chemical stability and thermal stability. activated carbon manufacturer When the activated carbon is in contact, the organic pollutants in the exhaust gas are adsorbed on the surface of the activated carbon, so as to be separated from the air flow to achieve the purification effect. The air flow discharged from the activated carbon adsorption bed has reached the emission standard, and the air can be directly discharged
