Adsorption type dryer adsorption theory and the process of their work

Adsorption dryer, generally adopts double tower, a tower of adsorption and desorption tower with the other. No heat regenerative adsorption dryer's actual working process of the points, regeneration, equalizing three phases, slight fever and a heat regenerative dryer by adsorption and regeneration, blowing cold, equalizing four phases constitute a cycle.

work, compressed air through A, B two alternately tower-type vessel filled with adsorbent, A tower in the pressure of work, High water vapor partial pressure) State of adsorption, another tower is close to atmospheric pressure ( Lower water vapor partial pressure) Situations or desorption heat condition, and then press the switch of the process, two towers work alternately.

adsorption is due to the interaction between adsorbate and adsorbent molecular adsorbate molecule predicted a phenomenon of international transfer. Physical adsorption method is often used to dry compressed air. When being dry compressed air and adsorbent ( No time limit) Contact with the water molecules in the air is spread on the adsorbent adsorption. At the same time, the adsorption of water molecules due to the thermal motion of water body and outer gaseous molecule collision, part of the left surface of the adsorbent for gas phase, namely happen when the same time the internal molecular adsorption quantity and stripping equals the amount, to reach a dynamic adsorption equilibrium and adsorption and the stripping process at this time on, but equal speed, the dynamic adsorption equilibrium was established under certain temperature and pressure condition, when the temperature and pressure changes, system balance relationship will be broken and establish a new equilibrium.
