一、常见干燥机工作原理
 
冷冻式干燥机采用降温结露的工作原理,主要由热交换系统、制冷系统和电气控制系统三部分组成。无热吸附式干燥机是根据变压吸附、再生循环的原理,利用自热进行吸附干燥。微热吸附式干燥机则是在无热吸附式干燥机的基础上增加了一个加热器,使用来再生的气流升高温度后对干燥剂进行加热再生。

二、能耗分析
 
冷冻式干燥机的能耗最大,既有一部分的电能消耗,又有一部分循环冷却水的消耗,因此产生的外部能源设施的运行能耗也是一笔不小的开支;无热吸附式干燥机的电能消耗很小,但再生气耗很大,导致空压机的能耗大大增加;微热吸附式干燥机的电能消耗主要是再生气的微加热,由于微加热的周期比较长,这就大大降低微热吸附式干燥机的能耗,而且由于微热吸附式干燥机的再生气耗较小,相应价低了空压机的能耗;从综合能耗上讲,微热吸附式干燥机在压缩空气净化领域存在很大的优势。

三、设计投资分析
 
1,空压站设备布置方面:冷冻式干燥机、无热吸附式干燥机和微热吸附式干燥机设备尺寸和基础布置并无太大差异。
 
2,管路系统设计方面:吸附式干燥机并不需要冷却水管道及阀门附件等,简化了空气净化系统的管路布置,降低了管道及附件的投资与维护,同时降低了外部能源设施及官网的投资及运行成本。
 
 
 
微热吸附式干燥机具有以下两个方面的优势
 
1、微热吸附式干燥机能耗较低,为企业节约了生产运行成本;
 
2、微热吸附式干燥机结构紧凑、操作简单、安全可靠,减少了空压站内管路与阀门的布置,使空气净化系统简洁、顺畅;同时减少了外部能源设施及管网的投资建设。
With the progress of science and technology and the improvement of people's living standards, in the industry, food and medicine and other fields, the quality of compressed air requirements are increasingly high, the current commonly used compressed air purification equipment mainly includes freeze dryer, no heat adsorption dryer and micro heat adsorption dryer.

One, common drying machine working principle
 
 
 
Refrigerated dryer adopts the working principle of cooling condensation, which is mainly composed of heat exchange system, refrigeration system and electrical control system. No heat adsorption dryer is based on the principle of pressure swing adsorption, regeneration cycle, the use of self-heat adsorption drying. Micro-thermal adsorption dryer is to add a heater on the basis of non-thermal adsorption dryer, and use the regenerative airflow to heat and regenerate the desiccant after increasing the temperature.

Ii. Energy consumption analysis
 
 
The refrigerated dryer has the largest energy consumption, which is not only a part of the electricity consumption, but also a part of the consumption of circulating cooling water. The energy consumption of the desiccating dryer is very small, but the energy consumption of the regenerator is very large, which leads to the energy consumption of the air compressor is greatly increased. The electric energy consumption of micro-heat adsorption dryer is mainly the micro-heating of re-gas, because the micro-heating cycle is relatively long, which greatly reduces the energy consumption of micro-heat adsorption dryer, and because the re-gas consumption of micro-heat adsorption dryer is small, the corresponding price is low energy consumption of air compressor; In terms of comprehensive energy consumption, micro-thermal adsorption dryer has great advantages in the field of compressed air purification.

Design investment analysis
 
 
1. Equipment layout of air compressor station: there is no big difference in equipment size and foundation layout between freeze dryer, non-heat adsorption dryer and micro-heat adsorption dryer.
 
 
2. Pipeline system design: adsorption dryer does not need cooling water pipes and valve accessories, which simplifies the pipeline layout of air purification system, reduces the investment and maintenance of pipes and accessories, and reduces the investment and operation cost of external energy facilities and official website.
 
 
Micro - thermal adsorption dryer has the following two advantages
 
 
 
1. Low energy consumption of micro-heat adsorption dryer saves production and operation cost for the enterprise;
 
 
 
2. Micro-heat adsorption dryer is compact in structure, simple in operation, safe and reliable, reducing the layout of pipelines and valves in the air compressor station, making the air purification system simple and smooth; At the same time, the investment in external energy facilities and pipe networks has been reduced.
