What are the main functions and functions of air compressor post-processing equipment

What are the main functions and functions of air compressor post-processing equipment? In an air compressor system, in addition to an air compressor to produce compressed air, post-processing equipment is also required to cool, dry and purify the air. Generally speaking, the commonly used air compressor post-processing equipment includes air storage tanks, filters and dryers.

　　 1. The main functions of the gas tank:

　　 The compressed air from the air compressor cannot be put into production immediately, and it needs to be temporarily stored in an air tank. The main functions of the gas storage tank are buffering, cooling, water removal and oil removal. When the air passes through the gas storage tank, the high-speed airflow hits the wall of the gas storage tank to generate confluence, and the temperature in the gas storage tank drops rapidly, so that a large amount of water vapor is liquefied, thereby removing a large amount of water and oil.

　　2, the main function of the pre-filter:

　　 Because the air in the atmosphere contains a lot of solid particles, oil molecules, dust and impurities, etc. After compressed air, the concentration of solid particles and other impurities will greatly increase. At this time, a pre-filter is needed to purify the compressed air. The main function of the pre-filter is to remove part of the liquid water, oil, and particles larger than 1 μm in diameter. Regardless of whether the back-end drying equipment uses other shell and tube refrigeration dryers or refrigerated refrigeration dryers, the pre-filter is mandatory. Otherwise, once the rust and other particles on the pipeline enter the evaporator, it will be greatly reduced The working efficiency of the cold dryer can even damage the evaporator.

　　3, the main function of the dryer:

　　 In addition to a large number of particles and impurities, compressed air also contains a large number of water molecules. The main function of the dryer is to remove the water molecules in the compressed air and reduce the water content in the compressed air to the required range (ie the dew point value required by ISO8573.1).

　　4, the main function of the post filter:

Remove the oil mist concentration in the compressed air to a higher U standard, while removing particles larger than 0.01 microns and oil content larger than 0.003PPM (under normal circumstances, there is almost no liquid water discharged from the post filter. If there is, It means that there is a problem with the steam separator or drain valve inside the dryer).
