For the treatment methods of organic waste gas in pharmaceutical factories, catalytic combustion, low-temperature plasma purifier+ultraviolet photolysis equipment condensation, spray tower washing acid-base waste gas, adsorption and desorption treatment, biofilm method and so on are generally adopted.
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 decomposed to produce a mixture containing electrons, various ions, atoms and free radicals.
Low-temperature plasma equipment mainly uses pollutants in waste gas and active particles such as high-energy electrons and free radicals to decompose in a short time, and finally achieves the purpose of degrading pollutants.
The process of waste gas treatment is probably as follows: waste gas source → enters the spray tower through the air duct (desulfurization reaction with the high-efficiency deodorizer in the spray tower) → the waste gas enters the water-gas separator to remove moisture → enters the low-temperature plasma purifier+ultraviolet photolysis equipment.
After treatment, the organic waste gas will eventually generate carbon dioxide and water, and the gas that finally meets the standard will be discharged into the atmosphere through the exhaust pipe.
Its equipment is simple to operate and its technology is mature, which is suitable for waste gas treatment with large air volume and high speed, which is one of the reasons why this method has developed rapidly in recent years.
