The coalescing filter is mainly designed for liquid-liquid separation. It contains two kinds of filter elements, namely: poly filter element and separation filter element. For example, in the oil dewatering system, after the oil flows into the coalescing separator, it first flows through the coalescing filter element. The coalescing filter element removes solid impurities and coalesces tiny water droplets into larger water beads. Most of the coalesced water beads can be separated and removed from the oil by their own weight and settled into the sump. Then the oil flows through the separation filter again. Because the separation filter has good lipophilicity and water repellency, the water is further separated. Finally, the clean, anhydrous oil flows out of the coalescence separator.
The oil first enters the lower part of the filter housing through the inlet pipe, and then flows into the filter core from the outside, then the coarse particles will immediately settle down and be discharged by the sewage valve. The smaller particles are intercepted by the filter core. Finally, the clean oil is collected by the filter element tray, and then flows out of the coalescing separator through the outlet pipe. As the amount of oil being processed increases, the contaminants deposited on the filter element will cause the pressure difference of the coalescer to rise. When the pressure difference rises to 0.15Mpa, it indicates that the coalescing filter element has been blocked and should be replaced.

The oil flows from the oil inlet of the coalescing separator into the first-level tray, and then shunts into the first-level filter element. After filtration, demulsification, water molecule growth, and coalescence, impurities are trapped in the first-level filter element, and the coalesced The water beads settle in the sedimentation tank, and the oil enters the secondary filter element from outside to inside, collects in the secondary tray, and flows out from the outlet of the coalescence separator. The material of the secondary filter element is hydrophobic, the oil can pass through smoothly, and the free water is blocked outside the filter element, flows into the sedimentation tank, and is discharged through the dirt release valve.
