How to choose compressed air treatment equipment for screw air compressor?

Update Time:2021/10/11
Compressed air treatment equipment is often referred to as refrigerated dryer, compressed air filters, air storage tanks. As we all know, the air compressed by the screw air compressor can not be used directly, because it contains a lot of moisture, oil and other pollutants, so it is generally matched with compressed air treatment equipment, and its role is to filter the impurities in the compressed air. If the compressed air is used directly without air treatment equipment, the following hazards will occur:

1, solid impurities: impurities less than 2μm in diameter, can not be filtered out. The unit will also constantly produce dust, rust slag and oil carbide, will accelerate the wear of gas equipment, leading to seal failure;
2, moisture: compressed air contains a lot of moisture, will rust equipment, pipes and valves. Under the condition of low temperature in winter, it is easy to freeze and block the orifice passage in pneumatic system. Even if the separation of clean pure saturated air, with the reduction of temperature, there will still be condensed water analysis report.

3. Oil: the oil in the compressed air mainly comes from lubricating oil. During the operation of the unit, part of the lubricating oil will enter the compressed air and make it polluted. Although the use of oil-free machine reduces the oil content in the compressed air of screw air compressor, it also produces side effects such as reduced life of wearing parts, corrosion of the machine internal and pipeline system, which is undoubtedly a threat to the pursuit of high reliability of automatic production line and gas equipment. To sum up, we can see the importance of post-processing equipment. So how to choose the rightCompressed air treatment equipment is often referred to as refrigerated dryer, compressed air filters, gas storage tanks. As we all know, the gas compressed by the screw air compressor can not be used directly, because it contains a lot of moisture, oil and other pollutants, so it is generally matched with post-processing equipment, and its role is to filter the impurities in the compressed air. If the compressed gas is used directly without post-treatment equipment, the following hazards will occur:?

Compressed air dryer: the dryer removes moisture and oil from the air compressor. At present, there are two kinds of compressed air dryers on the market: adsorption and refrigerated type. For general manufacturing enterprises, it is OK to choose refrigerated dryer, but for some enterprises with high requirements on the dryness of compressed gas, it is recommended to choose adsorption dryer.

Air storage tank: the main function of gas storage tank is buffer, cooling, water, oil. When the air passes through the tank, the high-speed airflow hits the tank wall to produce confluence, which makes the temperature drop rapidly in the tank and liquefied a large amount of water vapor, thus removing a large amount of water and oil. The gas storage tank can be purchased by regular manufacturers.

The role of the compressed air filter: compressed air in addition to water, oil, and dust and a variety of odor components, with physical methods to remove these compressed air pollutants equipment called filter. The higher the general series, the higher the filtration accuracy. It can be configured according to the level of compressed air quality requirements of the screw air compressor.

ince 2013, Scala Filtration has been delivering quality compressed air purification equipment and laboratory liquid nitrogen generators around the world.
