[0002] Industrial waste gas refers to gaseous pollutants generated by various processes, operations, or equipment during industrial production. These gases often contain a variety of harmful components, posing potential threats to the environment and human health. Pollutants must be removed from these gases. Purification devices are devices used to treat and purify industrial waste gas, primarily using cyclone technology to remove pollutants. These devices utilize centrifugal force and the rotating nature of airflow to separate particulate matter, gases, and other pollutants from the waste gas, achieving the desired purification effect.

[0003] For example, the patent with patent announcement number CN217340678 U records a cyclone-type waste gas washing and purification device for preparing amino acids by biological fermentation. The solution recorded therein is: by setting a fixed cyclone plate and an adjustable cyclone plate, and by setting a rotating rod, the position of the adjustable cyclone plate can be adjusted as needed, and then the density of the fixed cyclone plate and the adjustable cyclone plate can be adjusted, which can better perform cyclone dust removal operations on dust-proof gases. Combined with the spray component and the wire mesh demisting component, the waste gas treatment can be more efficient.

[0004] The above technology has the problem that when the exhaust gas enters the interior of the purifier, it may contain larger particles, which may easily cause local blockage inside the equipment, and may reduce the contact area between the exhaust gas and the purification medium, thereby reducing the purification efficiency.
