An adsorption dehumidification process method and apparatus. First, moisture-containing gas is injected into an adsorption dehumidifier (1) for dehumidification, and then, dehydration regeneration is performed on a moisture absorbent inside the adsorption dehumidifier (1) that has absorbed water. The dehydration regeneration comprises the following steps: step 1: cyclic heating up; step 2: cyclic dehydration regeneration; step 3: water discharging; and step 4: cooling. Step 3 is performed intermittently or continuously, and when the circulation gas contains 60 grams or more of water per kilogram of dry gas, the operation of step 3 starts while step 1 or step 2 is performed. The adsorption dehumidification apparatus comprises a dehumidification gas path having a to-be-dehumidified gas inlet (10), an adsorption dehumidifier (1), a dehumidified gas outlet (11) and a plurality of valves connected thereto, and further comprises a regeneration loop, a regeneration heater (6), a circulation fan (3) and a drainage device. The circulation fan (3) and the regeneration heater (6) are disposed on the regeneration loop, the regeneration loop connects the input end and the output end of the adsorption dehumidifier (1), the circulation fan (3) drives gas to cyclically flow on the regeneration loop, and the drainage device is communicated with the regeneration loop. |
