Coalescers are also known as coalescing fine filters or coalescing separators. Its core internals are made of polypropylene, polyester and other materials through resin bonding into wrinkled filter elements, and these filter elements are processed by oleophobic and hydrophobic technology.
Coalescers are used for: gas-liquid separation, which can remove trace liquid droplets (water droplets, oil droplets, etc.) and solid particles in the gas phase.
Liquid-liquid separation can remove the other micro-dispersed phase in the liquid phase (such as dewatering in oil, deoiling in water, and non-aqueous phase mixture separation). In industrial equipment, it is used to separate and purify various media, which can effectively protect key downstream equipment.
Equipment commonly used liquid-liquid separation coalescer The main equipment of the coalescer is the filter element, which is also the key component of the coalescer to produce a separating effect.
The coalescer is equipped with two kinds of filter elements with different functions-a coalescing filter element and a separation filter element. The medium to be dewatered enters the housing through the inlet of the filter separator. When the liquid passes through the filter element containing the special coalescing medium, the liquid flows from the inside of the coalescing filter element to the outside, and it will be emulsified by the four processes of filtration, demulsification and coalescence. The liquid is demulsified, and the small water drops after demulsification are aggregated into large water drops and settle to the bottom of the shell.
Some small water droplets that can get settled in the future flow with the liquid to the separation filter element. The separation filter element is made of special materials and has good hydrophobic performance. The small water droplets are completely and effectively blocked outside the filter element and coalesce again to form large water droplet sedimentation. Then ensure effective removal of moisture. The water level that has settled to the bottom of the casing is displayed by a liquid level gauge, which can periodically drain water and dirt through the drain valve. The oil flows from the outside to the inside of the filter element, and the medium separated from the moisture is collected by the separation filter element tray, and the water and oil flowing out from the separator outlet are discharged through different drainage ports.
