The process technology of the demister filter element can be summarized as the following three items:
1. the filter material is made of fiber and resin through a unique process, and has a fixed void structure. The filter material does not fall off, and the intercepted pollution particles do not generate a phenomenon of “unloading” due to the pressure difference and the pulsation of the flow rate.
2. Gradual aperture structure, which gradually decreases from the surface to the inner surface and along the flow direction, intercepts different sizes of pollution particles in layers to achieve deep layered scale, thereby greatly improving the service life.
3. the spiral belt with reinforced support to ensure the stability of the filter material.
For the selection of the demister filter oil filter, we have to consider the following five points:
1. the filter accuracy should meet the predetermined requirements.
2.to maintain adequate flow capacity for a longer period of time.
3. have enough strength, not because of the role of hydraulic damage.
4. the filter core has good anti-corrosion performance and can work permanently under the specified temperature.
Fiber mist removal filter introduction:
The main component of the fiber defogging filter element is an alkali-free glass fiber filter containing fluorine-containing silicone oil.
Fluoro-silicone oil glass fiber cotton (abbreviated as fluorine-containing silicone oil cotton) has excellent waterproof, oil and corrosion resistance, superior to organic silicon materials.
It is mainly applicable to chlor-alkali, organic silicon, and chloride industries. After use, the quality of liquid chlorine and hydrogen chloride is increased, the water content entering the turbine is reduced from 600ppm to less than 100ppm, and the water content of hydrogen chloride is reduced from 0.06% to 0.01%. %, The effect of dehydration is significant, which reduces the corrosion and leakage of the equipment and extends the cleaning equipment cycle from one month to more than one year.

Filtration process steps:
1. The mixed fluid enters the tank and is filtered through a pre-filter layer;
2. The fluid is filtered, intercepted, and aggregated to remove particulate impurities and collect liquid;
3. Collect the liquid sedimentation value at the bottom of the filter. Pure gas is discharged through the gas outlet.
