Velcon FO-644 separator Cartridge

Product Introduction:

Among the many stages of industrial production, liquid-liquid separation is a key operation, especially oil-water separation. Agglomeration separation filter plays an important role in this field, and the separation filter is the core component for achieving efficient separation.

 

Working principle

 In the coalescence separation system, the liquid first flows through the coalescence filter element. The coalescence filter aggregates tiny water droplets into larger ones, with most of the droplets settling and separating by their own weight. Afterwards, the liquid containing a small amount of small water droplets flows into the separation filter element. Separation filters usually use specially treated materials, such as polytetrafluoroethylene (PTFE), which have strong oleophilic and hydrophobic properties. When the liquid passes through the separation filter, water molecules are blocked on the outside of the filter due to the hydrophobicity of the material, and cannot pass through, while lipophilic liquids such as oil can smoothly pass through the filter, thereby achieving further oil-water separation and ultimately obtaining clean and anhydrous oil products. For example, in the oil-water separation system of a certain refinery, the oil products that have been preliminarily treated by the coalescence filter still have a certain proportion of water content. After passing through the separation filter, the water content of the oil products can be reduced to below 0.03%, greatly improving the quality of the oil products.

Structure and Materials

The structural design of the separation filter element is very refined, and some products use stainless steel mesh coated with double-sided polytetrafluoroethylene (such as 200 mesh). This structure allows the filter element to have both low flow resistance and high mechanical strength, ensuring that the liquid can pass smoothly and withstand a certain pressure without being easily damaged. From a material perspective, in addition to the aforementioned PTFE materials, there are also some that use specially treated glass fibers. These materials have been carefully selected and processed to meet the performance requirements of separation filters under different operating conditions. For example, in the purification scenario of aviation kerosene, the separation filter element needs to have extremely high reliability and filtration accuracy. The selected material should not only effectively separate moisture, but also not have any impact on the chemical properties of kerosene, ensuring the safe and stable operation of aviation engines.

 

Performance characteristics:

1. Efficient separation

The separation filter element, with its special material and structure, has extremely high separation efficiency for moisture. Taking a certain airline as an example, after adopting a coalescence separation filter, the fuel system failure rate was reduced by 50%, mainly due to the effective prevention of moisture from entering the engine by the separation filter, which extended the engine life.

2. Good chemical stability

It can work stably in various complex chemical environments without chemical reactions with the processed liquid, ensuring the reliability of the separation process and liquid quality. In chemical production, when dealing with oil-water mixtures containing multiple chemicals, the separation filter can continuously and stably perform its separation function without failure due to contact with certain chemicals.

3. Long service life

High quality materials and reasonable structural design enable the separation filter element to have a large pollutant holding capacity, which can maintain good separation performance for a long time, reduce replacement frequency, and lower maintenance costs. After a certain mechanical manufacturing enterprise adopted the coalescence separation filter element, the hydraulic system failure interval was extended to more than 8000 hours, and the maintenance cost was reduced by 25%. The long-life characteristic of the separation filter element is indispensable.

Application Fields

1. Petrochemical industry

In petroleum refining and chemical production, there is a wide demand for oil-water separation of crude oil, finished oil, and various chemical raw materials. Separating filter elements can effectively improve oil quality, reduce equipment corrosion, and enhance production efficiency. After a certain refinery adopted a coalescence separation filter element, the equipment corrosion rate decreased by 40% and maintenance costs decreased by 30%.

2. Aerospace

The quality of aviation kerosene is directly related to flight safety. Separation filters are used to remove moisture and impurities from kerosene, ensuring stable engine operation. After adopting a coalescence separation filter element, the engine life is extended by 20%, greatly reducing flight risks.

3. Industrial hydraulic system

The moisture and impurities in hydraulic oil can exacerbate equipment wear. Separating the filter element can effectively purify hydraulic oil, protect system components, and extend equipment service life. This is well demonstrated by the application case of a certain mechanical manufacturing enterprise.

4. Ship transportation

The marine engine fuel system uses a separation filter element to remove moisture and impurities from the fuel, reduce fuel consumption, and extend engine life. After a shipping company adopted it, fuel consumption was reduced by 8% and engine life was extended by 30%.

As an important component of agglomeration separation filter, separation filter plays an irreplaceable role in many industrial fields with its unique working principle and excellent performance characteristics, providing strong support for improving production efficiency and ensuring safe and stable operation of equipment.
