Technical Field

[0001] This utility model belongs to the field of waste gas pretreatment technology, and in particular relates to a waste gas pretreatment device with a self-cleaning filter. Background Technology

[0002] Waste gas pretreatment refers to the process of treating or purifying waste gas before it is released into the atmosphere. Its purpose is to reduce or eliminate harmful substances in the waste gas to protect the environment and public health.

[0003] Filtration is an important method in waste gas pretreatment, especially effective in treating particulate matter (such as dust, smoke, and fly ash). Filtration separates solid particles from waste gas through physical means, thereby reducing the pollution of the environment.

[0004] However, after prolonged operation, traditional filtration devices accumulate a large amount of solid particles on the filter surface, leading to filter blockage and affecting filtration efficiency and waste gas treatment efficiency. To solve this problem, regular cleaning or replacement of the filter is required, which not only increases operating costs but may also disrupt the continuity of waste gas treatment due to downtime for maintenance. Therefore, developing a filter device with self-cleaning capabilities is crucial for improving waste gas pretreatment efficiency and reducing operating costs. Utility Model Content
