It is contained moisture, oil, dust in the discharged from the compressor, the installation of equipment for removal of these is to be set up, after piping work for compressor.
It is called surge tank which absorbs pulsation discharged from compressor it is to be installed after setting After-Cooler in order to digest the influence of the pulsation. Compressed air sent to the Tank is cooled due to the heat emitted from the tank surface. So need for some means in order to discharge because of piled up condensation water on the tank bottom
Compressed air discharged from the compressor is usually a high-temperature state of 100 ~ 200 ℃, because adiabatically compress in the air intake. So, there is no danger of degree temperature level is 40 ℃, it called After-cooler. Classified as air-cooled and water-cooled.
Air dryer’s main function is removal of moisture. Air circuit (piping and valves, actuators, etc.) intended to prevent condensation in accordance with the partial temperature reduction due to the adiabatic expansion. There is some kinds model as below.
(1) Refrigerated Air dryer
Forcibly cooled by the compressed air in the refrigerator, and the condensed water to remove moisture.
(2) Desiccant Dryers
If there is not enough to be removed by Refrigerated Air dryer, you can utilize the dryer to remove with moisture adsorbed by drugs.
According to the need, it can be selected for method of using the adsorbent, but you’d get the result of dew point -40 ~ 50 ℃.
The adsorbent kinds are silica gel, synthetic Peugeot ride, cheoksan, and Mozarteum etc. and also there is method of medicine replacement.
You may need to select in consideration of problem, such as price and maintenance.
Compressed air coming into the filter has yeohoe movement due to the deep collector. And the solid hit and falls on wall of the vessel by centrifugal force. Furthermore, it needs to find method to remove fine material. In consideration of filter’s structure and element material, Filter, you need to select for use.
