Compressed air must be effectively filtered and dried before use. The usual way to deal with this is to place a large compressed air drying filter close to the compressor. The functionality of this filter is similar to a combination of three filters. This means it can replace mechanical aftercoolers, oil filters and filtered water filters.
Compressed air drying filter features:
Compressed air dry filters consist of a top cover, a middle tray and a bottom tray. Both the top cover and middle shell have two round holes, and the corresponding two round holes in the top cover and middle shell are arranged side by side. Two aluminum barrels are joined to form the first and second filter chambers. The middle shell and bottom shell are connected by screws, and the bottom edge of the bottom shell is hinged to the drainage device. chamber and compressed air outlet chamber.
The working principle of the compressed air drying filter:
Compressed air containing contaminants such as dust, oil, rust and moisture enters the first filter chamber 30 of the dry filter and expands to increase the space. The shell of the dry filter is made of aluminum alloy, effective heat dissipation through heat conduction, cooling the compressed air, less moisture in the cooled compressed air, so that part of the water vapor will be converted into water droplets. increase. At the same time, the first stage filter core condenses water vapor from all particles larger than 4 microns into large droplets.
As the compressed air rises while rotating, heavy water droplets that have passed through the first-stage filter collide on the surface and coalesce into large droplets. These large droplets flow to the bottom of the filter and exit the filter system through the float valve. Other impurities are then filtered out. His second filter element of the dry filter allows water droplets smaller than 4 microns to enter the he second filter element at a speed of 200-300 km/s. Due to the special construction of the filter element, the air flow constantly changes direction to pass through the filter element. An air vortex is formed, the compressed air is accelerated, and the water droplets are rapidly decomposed into water vapour.
It can be seen that when the compressed air passes through the first stage filter device, a coalescence effect occurs where larger particles are adsorbed onto the filter material and water condenses into larger droplets. Once in the separation chamber, the velocity of the compressed air is slowed, the particles are collected again, the water mist is again condensed in the honeycomb waterfall trap, and the water carrying the dirt particles flows along the bottom to the drain position where it is discharged. Automatic or electric drain valve, and compressed air flow. Thousands of tiny vortices are created when the second stage consists of a special cotton fiber filter. At the same time, the compressed air is accelerated by more than 10 times, the impurities are further filtered, and finally the compressed air required for combined use is formed.
1, Compressed air containing dust, oil, rust, water and other harmful substances enters the first stage filter of the compressed air filter.
2, When the compressed air passes through the first stage of the cartridge filter core to create a flocculation effect, the larger particles are adsorbed on the filter material and the water condenses into larger droplets.
3, The velocity of compressed air in the separation chamber was reduced, so the particles were collected again, and the water mist was condensed again in the honeycomb water collector.
4, The water laden with dirt particles flows along the bottom to the drain and is drained by an automatic or electric drain valve.
5. More than 95% of water droplets, oil and large particles in the compressed air are filtered by the 1st stage filter element, and the compressed air enters the 2nd stage filter element after the 1st stage filtration. 6. When the compressed air passes through the second stage special cotton fiber filter, thousands of small vortices are generated, the compressed air is accelerated by 10 times, the center of the vortex is like a tornado, and a vacuum is generated. To do. Filtered water droplets are gasified, converted, and filtered again, while particles as small as 5 microns are completely removed by a second stage filter.
7, Clean and dry compressed air without dust, rust, oil and water droplets is achieved by two-stage filtration, which ensures the normal operation of pneumatic equipment and prolongs the life of pneumatic equipment.
