Working principle：

Twin Towers type without heat regeneration dryer, the drying stage, air intake in the water is adsorbed on the desiccant, flowing in the adsorption bed at the same time, reducing the relative humidity of the air (RH). The adsorption bed every point, continuously absorb moisture from the surrounding air, until it reached the desiccant in specific relative humidity under the condition of equilibrium adsorption capacity. In this process, with the water being desiccant bed adsorption, will produce a "water move forward". The adsorption process will generate heat, make up dryer agent and air temperature. The flow of compressed air, the heat transfer from a ball to another for a ball. This generated a "heat striker", it moves in the "water striker" front. For no heat regeneration dryer, adsorption on the bed to keep such a heat front is very important, because in regeneration (desorption) the same amount of heat needed in the process, in order to have water adsorption desorption out. No heat regeneration dryer, the cycle time is very short, so in the heat by compressed air away before it will put into drying tower regeneration process. The regeneration process by using the same method, the water desorbed from the desiccant, but each other for the role. The regeneration process, ratio of blowing air drier the more a part of dry wet. The air is inflated to atmospheric pressure, into adsorption tower by the desiccant bed stored in the "heat of adsorption" heating. Adsorbent and purge moisture difference between the air, is the cause of the adsorption or desorption; and reduce the purge gas consumption of the energy needed, from the previously stored heat of adsorption because of the purge gas pressure is low (after decompression volume has been swelling), so only a small amount of purge gas can be adsorbed on the previous flow under the condition of water intake when blowing away. Sweep gas flowing in the adsorption bed, the humidity is gradually rising, at the exit of purge gas (dryer inlet), and dry it The relative humidity of the agent is in phase equilibrium
