Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separation, in particular to an oil mist separator structure. Background Art

[0002] The exhaust fans currently used in lubricating oil stations supporting units of petrochemical enterprises are unable to effectively collect and filter the oil mist generated by the oil stations and units. As a result, a large amount of oil mist is still directly discharged from the exhaust outlet, which fails to meet environmental protection requirements and is not convenient for timely cleaning of the filter components, thus affecting the oil mist separation operation.

[0003] In order to solve the above problems, an oil mist separator structure is proposed here. Utility Model Content

[0012] Preferably, the alarm and the pressure transmitter are both electrically connected to the control panel, and the alarm and the pressure transmitter are powered on and start working through the control panel.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By energizing the fan, a negative pressure is generated in the exhaust pipe, and then a negative pressure is generated in the cylinder, so that the oil smoke generated in the lubricating oil tank is introduced into the cylinder through the smoke guide pipe, and the oil smoke is filtered, separated, coalesced and settled through the coalescing filter element, thereby separating the oil and smoke. The oil will flow back to the lubricating oil tank through the return oil pipe, and the smoke will be discharged through the exhaust pipe. The pressure at the oil mist separator's oil smoke inlet end is monitored by the pressure transmitter.
