Operating Mechanism

 

Compressed air with high moisture flows into the drying tower. While it moves from the bottom to the top of the tower, moisture is adsorbed by the charged desiccant, producing dry compressed air. While the air is being dried in the drying tower, other towers engage in regeneration process to remove adsorbed moisture. During the regeneration process, dry compressed air from the drying tower is partially used. The dry compressed air at the outlet is heated by an electric heater, and moisture adsorbed by the desiccant in the regeneration tower is desorbed and discharged through a muffler at the bottom. Once the heating process is complete, heater operation is stopped, and the cooling process begins. The cooling process is a process to enhance adsorbing performances by cooling down the heated desiccant. Once the
cooling process is completed, the desiccant regeneration process from the regeneration tower is also finished. The purge valve from the regeneration tower is closed. Then, dynamic pressure process pressurizing regeneration tower starts. Once the dynamic pressure process is done, two towers are transferred. In the drying tower, then, the regeneration process is executed. In the towers where such regeneration process is completed, drying process is executed.

A series of above processes are automatically repeated according to specific time and sequence, producing dry air consecutively. In terms of an operating cycle, it is basically operated for 8 hours. Drying process is executed by two towers (4 hours each). Specifically, it is heated for 2 hours and 30 minutes and cooled for 1 hour and 27 minutes with 3-minute dynamic pressure.
