[0002] In industrial production and processing, oil mist separators are a crucial piece of equipment used to separate oil mist from gas or air in order to reduce environmental pollution, improve air quality, and recover valuable oils.

[0003] However, existing oil mist separators usually allow oil mist to directly enter the separator body for filtration and separation. But when the concentration of the feed oil mist is high, the oil mist filter media can easily reach saturation in a short time, resulting in decreased filtration efficiency, blockage, and frequent replacement of the filter media, which increases maintenance costs and downtime.

[0004] Therefore, how to effectively reduce the feed concentration of oil mist and extend the service life of oil mist filter media has become a technical problem that urgently needs to be solved in this field. Utility Model Content
