The adsorption dryer can also be called micro heat regeneration adsorption dryer. Its main structure is composed of tower a, Tower B, a inlet valve, B inlet valve, a regeneration valve, B regeneration valve, heater, silencer, two position five way electromagnetic pneumatic valve, program controller, single-phase valve, throttle orifice and other components.
The working procedure is as follows: during adsorption of tower a - a inlet valve (on) - B inlet valve (off) - a regeneration valve (off) - B regeneration valve (on), so that the compressed air enters tower a from the inlet valve of tower A. when passing through the tower from bottom to top, the internal alumina or molecular sieve adsorbs the water. The dry air comes out in this way. After 2 hours, it is switched to Tower B for adsorption. All cutting parts are in the opposite state to that during adsorption of tower a, Since the water adsorbed by tower a in the previous cycle is stored in the adsorbent in the tower, it is necessary to discharge the water of tower a out of tower a within the adsorption time of Tower B, so it is called tower a regeneration. Tower B is used to adsorb the dried air, depressurize it through the orifice plate, and then heat it to about 160 degrees in the heating barrel. In this way, the dry air with high temperature and low pressure enters tower a, and the moisture in the tower is discharged out of the tower from top to bottom.
After a cycle of 2 hours, switch to tower a for adsorption and Tower B for regeneration. In fact, it is one drying mode and two drying systems, so that dry compressed air can be supplied continuously without shutdown.
