Oil-water filter element is an instrument that separates oil and water. It is mainly a separator that removes impurities and water according to the density difference between water and fuel oil and uses the principle of gravity sedimentation. There are also separation elements such as a diffusion cone and filter screen inside.
Oil-water separation filter element Compressed air oil-water separation filter element is composed of a shell, cyclone separator, filter element, blowdown components, etc. When the compressed air containing a large amount of oil and water solid impurities enters the separator, it spins down along its inner wall, and the centrifugal action produced makes the oil and water separate out from the steam flow and flow down along the wall to the bottom of the oil-water separation filter element, and then the filter element performs fine filtration.
As the filter element is made of coarse, fine and superfine fiber filter materials, it has high filtration efficiency and low resistance. When the gas passes through the filter element, it firmly adheres to the fiber of the filter material due to the block of the filter element, inertial collision, Van der Waals force between molecules, electrostatic attraction and vacuum attraction, and gradually increases into liquid drops, which drip into the bottom of the separator under the action of gravity and are discharged by the drain valve.
Working principle:
1. The oily sewage is sent into the oil-water separation filteration elements by the sewage pump, and after passing through the diffusion nozzle, the large oil droplets float up on the top of the left oil collecting chamber;
2. The sewage containing small oil droplets enters the corrugated plate coalescer in the lower part, where the oil droplets in the coalescer part form larger oil droplets to the right oil collecting chamber;
3. Sewage containing smaller oil droplets passes through a fine filter to remove impurities from the water, and then enters a fiber polymerizer in turn, so that the small oil droplets are polymerized into larger oil droplets and separated from the water.
4. After separation, the clean water is discharged through the discharge port, the dirty oil in the left and right oil collection chambers is automatically discharged through the electromagnetic valve, and the dirty oil separated in the fiber polymerizer is discharged through the manual valve.
