Background
Coal chemical enterprises belong to the heavy pollution industry, the discharge point of VOCs gas is diversified and wide, and great pollution is caused to the surrounding environment of production enterprises. In recent years, with the increase of environmental protection treatment strength, the discharge of VOCs gas is required to be thoroughly treated.
At present, the main method for collecting and treating VOCs gas of various coal chemical enterprises is to convey volatile gases (VOCs) at various leakage points to an absorption tower for treatment after being collected by a gas collecting hood, a pipeline and a volatile gas induced draft fan.
The pain point of the prior treatment technology is as follows:
(1) a large amount of VOCs gas is often emitted from the shaft seal of the VOCs induced draft fan, so that secondary pollution to the environment is caused.
(2) If other seal assembly are installed additionally at the shaft seal position of the VOCs induced draft fan for sealing, the seal assembly can be worn and failed along with the operation of the fan. The seal assembly is cumbersome to replace.
(3) If the price of a special induced draft fan for purchasing the volatile gas is higher, the pollution treatment cost of enterprises can be increased.
