When the air compressor is working, the internal temperature of the head is very high, and the moisture in the natural air inhaled will be compressed by the two rotors during the operation of the air compressor, for energy conversion, and the electrical energy and mechanical energy of the operation of the air compressor will be converted into compressed air heat energy, resulting in an increase in air pressure and temperature. At this time, the water in the natural air will form water vapor during the operation of the air compressor, becoming a supersaturated water vapor state, and entering the next cycle with the compressed air.
At this time, the compressed air is a mixture of water and air, and the pressure and temperature are very high, reaching the air compressor exhaust pressure index, usually the temperature reaches 70 ~ 90 ° C or more, this temperature is much higher than the normal ambient temperature, and it is necessary to further cool down the air compressor after the cooler.
When the temperature is above the ambient temperature, there will be a large amount of water precipitation, then the water in the compressed air should be released for the first time, and it is necessary to install an automatic blowdown valve in the compressed air pipeline to discharge the water formed in the process of air compression. Of course, the discharge is not just pure water, there will be a lot of solid dust mixture, and some oil. Then the compressed air enters the gas tank, which can not only provide a buffer and storage space for the compressed air, but also reduce the pressure and cool down.
When the compressed air passes through the tank, the high-speed air flow hits the wall of the tank to produce a confluence, and the temperature in the tank drops rapidly, so that a large amount of water vapor is liquefied and condensed water is formed. If caught in wet weather or winter, more condensation will form. Because the gas storage tank is a metal material, if it does not discharge water for a long time, rust will occur. Gas storage tank is a pressure vessel, such as rust may occur safety accidents, so it is necessary to discharge the water in the gas storage tank.
