Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device. Background Art

[0002] Waste gas is one of the main sources of environmental pollution. Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. Industrial waste gas generally contains chemical components that are harmful to the human body. When discharged into the atmosphere, it will pollute the air. These substances enter the human body through different pathways. Some of them directly cause harm, while others have an accumulation effect, which will more seriously endanger human health. Industrial waste gas can be seen everywhere in the industrial processing and production process. For example, when processing and producing fasteners, some waste gas generated after combustion needs to be treated before it can be discharged to avoid affecting the surrounding environment and personnel. Therefore, waste gas treatment devices are needed. At present, some traditional waste gas collection devices are very inconvenient to move, which makes the waste gas collection devices very limited.
