[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas discharged has a strong odor, seriously polluting the environment and affecting human health. Therefore, air treatment equipment is needed to treat the harmful gases discharged from the factory so that they meet the corresponding emission standards before being discharged. Therefore, many air treatment devices are produced in operation. However, many air treatment devices in the prior art are large in size and relatively fixed in position. Once damaged, they are difficult to disassemble.

[0004] Although the above device can achieve the purpose of facilitating the separation of the machine body and the connecting pipe when in use, it still uses bolts for fixing during specific use. The cumbersome method of using bolts mentioned in the background technology has not been completely solved. Although the steps of fixing and disassembling with bolts have been simplified to a certain extent, the staff still needs to use corresponding tools to unscrew and tighten the bolts, which will also delay the separation time of the machine body and the connecting pipe, so it needs to be improved.
