Volatile Organic Compounds (VOC) exist in a gas form at normal temperature, VOC is one of the most common atmospheric pollutants, and VOC waste gas mainly comes from various industrial fields such as plastics, rubber processing, paint production, automobile paint spraying and coating production. The persistence of the VOC gas in the working environment can not only seriously hurt the human health of the operating personnel, but also control the concentration of the VOC gas in the working environment to be beneficial to ensuring the fire safety because the VOC has flammability; since VOC can participate in atmospheric photochemical reaction and easily cause greenhouse effect, directly discharging VOC gas in the working environment into the atmosphere causes serious pollution to the atmosphere.

In order to meet the requirements of environmental protection and safety, the VOC gas treatment mode in the prior art mainly comprises the following steps:

1. direct high-temperature incineration needs to maintain higher combustion temperature in order to ensure the sufficient combustion of the VOC, so that fuel needs to be added to ensure the sufficient combustion of the VOC, and the energy consumption and the cost are higher.

2. The low-temperature catalytic incineration reduces the ignition temperature of the VOC gas by using the catalyst, so that the VOC gas is combusted and is oxidized and decomposed into carbon dioxide and water, energy can be saved, but because the VOC gas contains dust particles and fog drops, the dust particles and the fog drops can influence the efficiency of the catalyst, the ignition temperature is increased, and the energy consumption is increased.

3. In the existing incinerator treatment step, dust and impurities in the VOC gas are removed by adopting a dust removal bag, but the dust removal bag needs to regularly clean accumulated dust on the wall of the dust removal bag so as to ensure that the filtering efficiency of the dust removal bag is not influenced, and the existing dust removal mode basically adopts manual dust removal or a hairbrush is arranged beside the dust removal bag to brush the accumulated dust; manual dust removal is troublesome, and accumulated dust is removed after the dust removal bag needs to be detached.
