一、常見干燥機工作原理
 
冷凍式干燥機采用降溫結露的工作原理,主要由熱交換系統、制冷系統和電氣控制系統三部分組成。無熱吸附式干燥機是根據變壓吸附、再生循環的原理,利用自熱進行吸附干燥。微熱吸附式干燥機則是在無熱吸附式干燥機的基礎上增加了一個加熱器,使用來再生的氣流升高溫度后對干燥劑進行加熱再生。

二、能耗分析
 
冷凍式干燥機的能耗最大,既有一部分的電能消耗,又有一部分循環冷卻水的消耗,因此產生的外部能源設施的運行能耗也是一筆不小的開支;無熱吸附式干燥機的電能消耗很小,但再生氣耗很大,導致空壓機的能耗大大增加;微熱吸附式干燥機的電能消耗主要是再生氣的微加熱,由于微加熱的周期比較長,這就大大降低微熱吸附式干燥機的能耗,而且由于微熱吸附式干燥機的再生氣耗較小,相應價低了空壓機的能耗;從綜合能耗上講,微熱吸附式干燥機在壓縮空氣凈化領域存在很大的優勢。

三、設計投資分析
 
1,空壓站設備布置方面:冷凍式干燥機、無熱吸附式干燥機和微熱吸附式干燥機設備尺寸和基礎布置并無太大差異。
 
2,管路系統設計方面:吸附式干燥機并不需要冷卻水管道及閥門附件等,簡化了空氣凈化系統的管路布置,降低了管道及附件的投資與維護,同時降低了外部能源設施及官網的投資及運行成本。
 
 
 
微熱吸附式干燥機具有以下兩個方面的優勢
 
1、微熱吸附式干燥機能耗較低,為企業節約了生產運行成本;
 
2、微熱吸附式干燥機結構緊湊、操作簡單、安全可靠,減少了空壓站內管路與閥門的布置,使空氣凈化系統簡潔、順暢;同時減少了外部能源設施及管網的投資建設。
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.
