A、吸附操作温度：一般<50℃，否则降低吸附剂的去湿能力。adsorption operating temperature: generally otherwise reduce the adsorbent dehumidification> B、吸附操作压力：压力对吸附剂去湿能力影响很小，但应避免压力波动而影响床层的稳定性。Adsorption operating pressure: the pressure has little effect on the desiccant ability of the adsorbent, but the stability of the bed should be avoided due to the pressure fluctuation.

C、吸附剂寿命：决定于吸附剂种类和操作情况，一般1～3年。Adsorbent life: depends on the type of adsorbent and operating conditions, generally 1 to 3 years.

D、再生温度：取决于吸附剂种类，分子筛再生温度200～300℃。Regeneration temperature: depending on the type of adsorbent, the regeneration temperature of molecular sieve is 200 ~ 300℃.

E、再生气流量：约为气体流量的5～15％，太小不足以在规定的时间内把吸附剂提高到规定温度，太大容易使床层松动，降低吸附剂寿命。Gas flow rate: about 5 ~ 15% of the gas flow rate, too small to raise the adsorbent to the specified temperature within the specified time, too large will easily loosen the bed and reduce the life of the adsorbent.

F、冷却终了温度：约50℃。Cooling end temperature: about 50℃.
