<p>A drying system and a drying method are disclosed. The drying system includes a drying device (20) and a drying gas supply equipment (10) which includes an absorption tower (12), a generator (11) and a crystallizer (141) accepting and cooling the absorbent from the absorption tower (12) and/or the generator (11) to form crystals and remainder absorbent. The after-crystallizing absorbent is sent to the generator (11) while the crystals are sent to the absorption tower (12). The absorption tower (12) is equipped with dried gas pipes (123) on its top to pipe the dried gas to the drying device (20) and the drying device (20) is equipped with humid gas pipes (121) at its bottom to pipe the humid gas to the absorption tower (12). The drying method chiefly includes a drying gas circulation and an absorbent circulation using remaining heat as heat source.</p> |
