You shouldn't know there is dirt in the head of your screw air compressor!

Everyone who operates the air compressor must know that the screw air compressor has been running for a long time and impurities will appear inside the head.There are too many impurities in the screw air compressor head, so it is necessary to treat the compressed air impurities in time before it can be used in production.Compressed air produced by screw compressors generally contains solid impurities and moisture, so the compressor is a complete system.Compressed air treatment is the process of preliminary treatment of compressed air by filtering particle impurities and oil and liquid impurities through filters.The filter element of common filter is closed at the bottom, and impurities generally accumulate inside the filter element.It passes through the filter element to the bottom of the filter and then through the active drain to remove the impurities.However, there are some problems in this process. Solid impurities can not be completely removed from the filter element and will stick to the inner wall of the filter element.The compressed air resistance is then increased so that the moisture and oil content will follow the compressed air.

Equip post-treatment equipment because it cannot be completely removed, freeze dryer.The main purpose is to cool the compressor so that the water-bearing compressor is in a low temperature state. Some of the water is condensed into liquid state and then removed by active drain.However, the freezing type has certain limitations. The temperature of the refrigerant must not be lower than 2 degrees Celsius, otherwise ice will appear and the pipeline will be blocked.To get a very low dew point, only the compressor power can be increased.This increases costs.

Adsorption drying treatment is mainly absorbed by adsorbent, which absorbs water under high pressure and regenerates under low pressure. In this way, we can circulate and reciprocate to get the dry air we want.Of course, if there is no perfect one, there will also be a point of disadvantage. The filling of adsorbent can not be perfectly fine, which easily leads to high energy consumption. In this case, it will be difficult to replace adsorbent.
