Compressed air drying machine equipment, refrigerated compressed air dryer using the principle of cooling air and reducing air temperature, the moisture in the wet air is precipitated from the air after condensation to obtain drier air. The adsorption compressed air dryer uses the principle of pressure swing adsorption, when the wet air passes through the adsorbent, the water is adsorbed by the adsorbent to obtain dry air.
Compressed Air Dryers
The working principle of a compressed air dryer is based on the relationship between humidity and temperature in humid air. When humid air is compressed by a compressor, it is compressed to a high pressure state, but the temperature also increases accordingly. Then, the compressed air passes through a dryer, where the moisture is removed, producing dry air. Finally, the dry air is further purified through a filter to remove suspended particles and solid impurities.
There are several common types of compressed air dryers, including refrigeration dryers and adsorption dryers. A refrigerated dryer cools compressed air to condense and remove moisture. Adsorption dryers use adsorbents to adsorb moisture, which is then released through a regeneration process. Membrane dryers use special membranes to selectively permeate water molecules to achieve air drying.
Refrigerated Compressed Air Dryer
refrigeration compressed air dryer (hereinafter referred to as cold and dry), is based on the principle of freezing dehumidification, compressed air drying equipment. After the dry and dry compressed air, the finished product gas pressure dew point of up to 2 ℃ (atmospheric dew point -23) the following.
