1.1 适用吸附式干燥机的场合

Apply to the situation of adsorbed dryer 

按GB/T13277 -91《一般用压缩空气质量等级》（等效采用ISO8573第II部分）规定，压缩空气含水等级共分6级，其中1~3级压力露点均在-20℃以下，必须使用吸附式干燥机才能达到。其典型的应用领域有：摄影胶片、微电子芯片（1级，-70℃）、精密喷涂（2 级，-40℃），粉状产品输送（3级，-20℃）等。 有些场合虽然对压缩空气的露点要求并不十分严格，但输气管道要通过0℃以下环境且外部不复保温材料时，为了防止所输送的压缩空气中残余水分在管道内冻结，就必须使其压力露点低于环境所能达到的最低温度，此时也应当适用吸附式干燥机对压缩空气进行除水处理。

According to GB/T13277-91 "general quality level of the compressed air (equivalent ISO8573 part II) regulation, the water level is divided into 6 levels of compressed air, including grade 1 ~ 3 pressure dew point are in - below 20 ℃, adsorption dryer must be used to achieve. Its typical applications are: film, microelectronic chip (level 1-70 ℃), precision spraying (level 2, and 40 ℃), the powdery product delivery (level 3, - 20 ℃), etc. Although some occasions to the dew point of compressed air is not very strict, but gas pipeline through below 0 ℃ environment and external thermal insulation material, no in order to prevent the transmission of residual moisture in the compressed air in the pipe frozen, it must make its dew point pressure is lower than environment can achieve the lowest temperature, this is also adsorption of compressed air dryer shall apply in addition to water treatment. 

经吸附式干燥机处理的空气露点可涵盖冷冻干燥器的处理效果，所以原则上一切使用冷冻干燥器的场合都可以用干燥器作代替，但反过来是不行的。由于冷冻式干燥机的能耗比吸附式干燥机低得多，因此用吸附式干燥机替代冷冻式干燥机在经济上肯定是不合算的。

Air dew point can be treated by adsorption dryer covers the treatment effect of freeze dryer, so in principle all use the occasion of freeze dryer can use instead of a dryer, but the reverse is not enough. Due to the energy consumption of freeze drying machine than adsorption type dryer is much lower, so use adsorption dryer instead of freeze drying machine on the economy is certainly not worthwhile. 

1.2 再生方式选择

1.2 regeneration mode selection 

成品气露点和再生能耗是选择吸附式干燥机时必须考虑的两大因素。一般来说，两者不能兼顾，即要获得低露点的压缩空气，就必定要付出较多的能耗代价。

The two factors that must be considered in the choice of the adsorption type dryer are the gas dew point and the energy consumption of the finished product. Generally speaking, the two cannot be done together, namely to obtain the compressed air of low dew point, must pay more energy cost. 

按吸附理论，吸附式干燥机的基本形式只有无热再生和有热再生两种。无热再生干燥器由于以变压吸附为基础，采用了短周期循环工作制，经它处理的压缩空气露点无论在深度或稳定性方面都比有热再生干燥器好，且再生能耗已十分接近理论底线，所以自从无热再生吸附式干燥机出现后，油热再生干燥器就有退出应用领域的趋向。

According to the theory of adsorption, the basic form of adsorption dryer is only two kinds of thermal regeneration and thermal regeneration. No heat regenerative dryer because on the basis of pressure swing adsorption, used the short cycle of work, by its handling of the compressed air dew point both in depth and stability is better than a heat regenerative dryer, and renewable energy has been very close to the theory of the bottom line, so since there is no heat regenerative adsorption dryer, oil heat regenerative dryer will have a tendency to exit the application. 

上世纪90年代中期出现在我国的“微热”再生干燥器是比较“另类” 的，其初衷显然是为了进一步降低再生耗能；但这一创建在许多基本问题上目前还停留在泛泛而谈中，例如有关微热干燥器耗气量可见的“样本数据”就有3%~11%等多种版本，需在理论上作翔实论证，以消除可能出现的技术误导。用户在选型时没有必要去轻信这些诱人的 “样本数据”，事实上任何类型的吸附式干燥机都要消耗较多的再生能量（无论是气耗或热耗，最终都以电费形式列支），必要时对选型设备进行“能量衡算”不失是一种谨慎的举措。

The "micro-hot" regenerative dryer that appeared in China in the mid-1990s was "different", apparently intended to further reduce the use of renewable energy. But this created on many basic problems are still stay in general, such as the micro thermal dryer visible "sample" gas consumption is 3% ~ 11%, and other version, need to make detailed argumentation in theory, in order to eliminate the possibility of technology is misleading. Users in the selection when there is no need to take these tempting "sample", in fact, any type of adsorption dryer consumes more renewable energy (either gas or heat consumption, finally all is listed in the form of electricity) and, when necessary, "energy balance" on the selection of equipment in do not break is a prudent move.
