Description

Technical Field

[0002] Adsorption dryer is a commonly used drying equipment. Its principle is to use the difference between the volume of water and air molecules to filter out the saturated water vapor in the compressed air through a special molecular sieve for gas purification. The water molecules can be easily adsorbed in the molecular sieve particles, and then the molecular sieve can be restored by regeneration method. The dew point of the compressed air can easily reach -40℃. The adsorption dryer can dry the material in a short time, quickly and efficiently. The operation of the adsorption dryer is simple, the controllability is strong, and it is easy to maintain and clean. When in use, the adsorption dryer will cool the compressed air to a temperature that can be dried.
