Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to an air pretreatment device. Background Technique

[0002] Before the boiler flue gas is discharged, it needs to be purified. The first step of the purification treatment usually adopts a physical filtration method to pre-treat the flue gas, so as to remove most of the dust doped in the flue gas.

[0003] At present, most of the used treatment devices use multiple filter screens to filter the flue gas to gradually filter the dust with different particle sizes in the flue gas. After long-term use, the filtered dust will adhere to the filter screen and block the filter screen, thus affecting the normal flow of the flue gas. Therefore, it is necessary to clean the filter screen, but most of the treatment devices need to take out the filter screen to complete the cleaning, and the operation is relatively troublesome and needs to be improved.
