The coalescing separation filter is used in the oil-water separation system to separate the oil-water mixture, the suspension solution, the milk solution, etc., and the use process of the coalescing separation filter in the system is divided into:
Solid-liquid separation---demulsification---coagulation---separation---sorption. In the system, the larger the ratio of the coalescing filter element and the separation filter element, the better the coalescence effect and the faster the separation speed. There are currently two types of water treatment cartridges that have been standardized.
The coalescing filter has the dual function of filtering impurities and agglomerating moisture from aviation kerosene, and is an important functional component of the fine filter.
It meets the needs of a variety of fine filters used in fixed mobile fueling facilities.
1. Filter paper with multi-layer composite structure, high filtration precision;
2, carefully set and specially treated glass fiber layer, good coalescence effect.
3, the flow density is large, reducing the size of the fine filter;
4. Large dirt holding capacity and long service life;
5, the specifications are complete, to meet the needs of a variety of fine filters.
The coalescing separator is mainly designed for liquid-liquid separation. It contains two kinds of filter elements, namely: a polymer filter and a separation filter. For example, in the oil dewatering system, after the oil flows into the coalescing separator, it first flows through the coalescing filter element, and the coalescing filter element filters out solid impurities and coalesces the tiny water droplets into larger water droplets. Most of the agglomerated water droplets can be separated from the oil by their own weight and settled into the sump. The oil then flows through the separation filter. Since the separation filter has good oleophilic water repellency, the water is further separated, and finally, the clean, anhydrous oil flows out of the coalescing separator. The oil first enters the lower part of the filter housing from the inlet pipe, and then flows the filter core from the outside to the inside. At this time, the coarser particles are immediately precipitated, discharged by the drain valve, and the smaller particles are intercepted by the filter element.
