Pharmaceutical plant exhaust mainly contains a large number of acid and alkali exhaust and malodor, such as direct emissions will cause great pollution of the surrounding air, exhaust only after reaching the "malodor pollutant emission standards" (GB14554-93) in the second level of the standard value of the exhaust can be discharged, that Pharmaceutical plant exhaust treatment methods are what?
Organic waste gas treatment for pharmaceutical factories will generally use catalytic combustion, low temperature plasma purifier + UV photolysis equipment condensation, spray tower washing acid and alkali exhaust, adsorption and desorption treatment, biofilm method.
Low-temperature plasma purification:
The principle of this method is that when the applied voltage reaches the discharge voltage of the gas, the gas is broken through, resulting in a mixture containing electrons, various ions, atoms and free radicals.
Low-temperature plasma equipment is mainly used in the waste gas pollutants and high-energy electrons, free radicals and other active particles, in a short period of time to produce decomposition, and finally reached the purpose of degrading pollutants.
The process of waste gas treatment is as follows: waste gas source → through the air duct into the spray tower (and the spray tower in the efficient deodorant desulfurization reaction) → waste gas in the water-gas separator will remove the water → into the low-temperature plasma purifier + UV photolysis equipment.
Organic waste gas is then processed to generate carbon dioxide and water, and the gas that finally meets the standards will be discharged into the atmosphere through the exhaust pipe.
The operation of its equipment is simple, the process is mature, suitable for large air volume and high speed flow of exhaust gas treatment, which is also one of the reasons why the method has developed rapidly in recent years.
