With the rapid development of the plastics industry, plastic granulation has become an important link in the production process of plastic products. However, in the process of plastic pelletizing, a large amount of waste gas will be generated, which will not only seriously pollute the environment, but also cause harm to the health of workers. Therefore, in order to protect the environment and the health of workers, effective waste gas treatment measures must be taken.
In the plastic pelletizing process, waste gas treatment equipment is indispensable. Here are a few commonly used waste gas treatment equipment:
1.Scrubber.
Scrubber is a common waste gas treatment equipment, and its main function is to remove harmful substances in the exhaust gas by spraying the washing liquid. In the scrubber, the exhaust gas passes through the packing layer and is in full contact with the washing liquid, which can absorb the harmful substances in the exhaust gas, so as to achieve the purpose of purifying the exhaust gas.
2.Activated carbon adsorber.
Activated carbon adsorber is an efficient and reliable waste gas treatment equipment, and its main function is to remove harmful substances in the waste gas by using the adsorption performance of activated carbon. In the activated carbon adsorber, the exhaust gas passes through the activated carbon layer, the harmful substances are adsorbed on the surface of the activated carbon, and the purified gas is discharged from the activated carbon adsorber.
3.Photocatalytic oxidizer.
Photocatalytic oxidizer is a new type of waste gas treatment equipment, whose main function is to remove harmful substances in the waste gas by photocatalytic oxidation reaction. In a photocatalytic oxidizer, the harmful substances in the exhaust gas are oxidized and decomposed under the action of ultraviolet rays and catalysts to form harmless substances.
4.Burner furnace.
The combustion furnace is a kind of high-temperature exhaust gas treatment equipment, and its main function is to remove harmful substances in the exhaust gas by combustion. In the combustion furnace, the exhaust gas passes through the high-temperature combustion zone, and the harmful substances are oxidized and decomposed into harmless substances. At the same time, the combustion furnace can also burn and utilize the combustibles in the exhaust gas to reduce energy waste.
To sum up, the waste gas generated in the plastic pelletizing process must be treated effectively. Commonly used waste gas treatment equipment includes scrubbers, activated carbon adsorbers, photocatalytic oxidizers and combustion furnaces. Choosing the right waste gas treatment equipment according to the actual situation can effectively purify the waste gas and protect the environment and the health of workers.
