Plastic waste gas treatment

——————————————— ◆  Exhaust gas analysis  ◆ ———————————————

Characteristics of plastic waste gas
1. The composition and content of plastic waste gas are complex, and the single targeted treatment method is basically unable to handle;
(1) complex composition of natural or synthetic resin
(2) there are many kinds of additives
(3) the main components of waste gas in different processes are different
(4) the waste gas content of different manufacturing processes is different
2. Most of the waste gas is organic compound, which is difficult to cure or easy to secondary pollution in traditional way;
3. The waste gas contains toxic substances and has obvious peculiar smell;
4. Obvious particles may exist in some processes.
 

 

Composition of plastic waste gas
Main components of plastic waste gas: the odor components of rubber and plastic waste gas are complex and variable, which can be roughly divided into 5 categories:
① sulfur compounds: such as H2S, SO2, mercaptans and thioethers;
② dust: such as carbon black;
③ chlorinated compounds: such as amides and indoles;
④ hydrocarbon: such as alkane, olefin, alkyne and aromatic hydrocarbon;
⑤ oxygenated organics: such as alcohols, phenols, aldehydes, ketones, organic acids, etc;
Among them, inorganic substances include H2S, SO2, carbon black, etc., and most of the original substances produced by odor gases are organic substances. These substances are harmful to human health.
Because there are many waste gas producing parts of rubber and plastic, and they are scattered in the workshop, so the waste gas must be collected before the waste gas treatment, so it needs to be collected by the gas collection system for unified treatment.

Process Brief
(1) the collected exhaust gas enters into the ionization trapper. When the flue gas passes through, the dust and tar in the flue gas are ionized under the action of electric charge, moving towards the charged metal wire and pipe wall, and losing the electric charge. Under the action of gravity, they fall to the bottom of the ionization trapper and flow out, so that the pollutants can be degraded and removed.
(2) the captured waste gas enters into the deep purification system. When the activated carbon adsorber is close to saturation, the hot gas flow is used to desorb the activated carbon adsorber, and the organics are desorbed from the activated carbon. In the desorption process, the organic waste gas has been concentrated, and the concentration is dozens of times higher than the original, reaching more than 2000 ppm. The concentrated waste gas is sent to the catalytic decomposition unit, and finally becomes CO2 and H2O. After deep purification, it is discharged through the fan chimney.
