The coalescence filter element is processed by a variety of composite materials through a special process. It has hydrophilic characteristics. It can not only filter out the mechanical impurities in the medium, but also remove the emulsified water from the medium through demulsification and coalescence. The filter element is separated and coalesced into larger water droplets to facilitate further purification of the medium.
Scope of application
1. Aviation fuel, gasoline, kerosene;
2. Liquefied petroleum gas, stone tar, benzene, toluene, xylene, cumene, polypropylene, etc.;
3. Turbine oil and other low viscosity hydraulic oil and lubricating oil;
4. Cycloethane, isopropanol, cycloethanol, cycloethyl ketone, etc.;
5. Other hydrocarbon compounds
Principle of filtration
The droplets of oil, water and other liquids are captured by the ultrafine fibers inside the coalescer. These micron-sized fibers form a tortuous channel for the airflow, forcing solid particles and liquid droplets to collide, diffuse and intercept directly, and intercept directly. Under the action of this filtering mechanism, it is captured by the ultrafine fibers, and the surface tension of the liquid causes the small droplets to coalesce into larger droplets. Due to gravity, the large droplets settle to the bottom of the container.
The glass fiber coalescing filter element is made of high-density gradient glass fiber. In order to reduce damage and loss, it is designed as an integral monolithic tube structure. The surface of the filter element is treated with hydrophobic and oleophobic treatment, which can meet the requirements of various precision levels.
Polyester fiber coalescence filter element The filter element is usually made of polyester fiber synthetic material, which has good compatibility with various fluids. The filter element is spirally rolled with a multi-layer structure, and each layer uses fibers with different properties. The expected filtration accuracy can be achieved by controlling the shape, size, thickness and density of each layer of fibers.
The coalescing filter element mainly uses surface-treated glass fiber or polyester fiber as the coalescing medium. The structure of the filter material is specially designed to make the filter medium have good coalescence performance. The filtration accuracy can reach 0.1μm.
