    • 關于冷干機和吸干機的一些建議
    • 本站編輯:杭州力諾機械設備有限公司發布日期:2020-01-06 20:50 瀏覽次數:
    冷干機與吸干機均屬于壓縮空氣干燥用設備,它們都廣泛應用于工業中,但沒有一種干燥設備適合所有的工況,在選擇方面,一般從機械設備的性能需求、安裝環境和所需干燥程度、使用及維護的成本來考慮選用哪種設備或者設備的搭配來滿足需求。
    我們的建議:
     
    1.如管路布置區域溫度長期低于2℃,且對壓縮空氣壓力露點的要求值低于常年極低溫度值5℃以上,建議只配置吸干機。
     
    2.明確用戶對壓縮空氣使用時的實際露點值的需求,與第1點對比,取低值。設備選型時均需以滿足該露點的基礎上,再考慮同類設備間不同的節能配置,否則得不償失。
     
    3.建議在吸干機前安裝冷干機,冷干機可以去除壓縮空氣中大部分的水與油,可減輕吸干機的除水負荷,確保其干燥效果,也能減小吸干機的選型,同時降低油類雜質對吸附劑的污染,使干燥效果能維持更久,延長吸附劑更換時間。
     
    4.在同等情況下,吸干機無論在穩定性還是在效果上都要略優于冷干機,只是因為要損耗一定量的再生氣。在機械設備的性能需求、安裝環境和所需干燥程度、使用及維護的成本來綜合權衡,分析利弊進行選擇。
     
     
     
    干燥機的未來發展:
     
    1.深入研究干燥機理和物料干燥特性,掌握對不同物料的最優操作條件下,干燥機改進和不斷開發,如:干燥機的自動控制技術以保證最優操作條件的實現;設備大型化、高強度、高經濟性以及改進對原料的適應性和產品質量。
     
    2.進一步研究和開發新型高效和適應特殊要求的干燥機,如組合式干燥機、微波干燥機和遠紅外干燥機等。
     
     
    3.環保、節能和能量綜合利用,如采用各種聯合加熱方式,移植熱泵和熱管技術,開發太陽能干燥機等;在改進干燥機的環境保護措施以減少粉塵和廢氣的外泄等,也將是需要深入研究的方向。
    Both the cold dryer and the suction dryer belong to the compressed air drying equipment, which are widely used in the industry, but there is no drying equipment suitable for all working conditions. In terms of selection, generally from the performance requirements of mechanical equipment, installation environment and required drying degree, use and maintenance costs to consider which equipment or equipment matching to meet the needs.
    Our proposal:
     
    1. If the temperature of the pipeline layout area is lower than 2 ℃ for a long time and the required value of the pressure dew point of the compressed air is lower than the extremely low temperature value of the whole year by more than 5 ℃, it is recommended to only configure the dryer.
    2. Clarify the user's demand for the actual dew point value when using compressed air, and take the low value compared with point 1. On the basis of meeting the dew point, different energy-saving configurations among similar equipment shall be considered in equipment selection, otherwise, the loss will be outweighed.
    3. It is recommended to install a cold dryer in front of the dryer, which can remove most of the water and oil in the compressed air, reduce the water removal load of the dryer, ensure its drying effect, reduce the selection of the dryer, reduce the pollution of oil impurities on the adsorbent, maintain the drying effect for a longer time, and extend the replacement time of the adsorbent.
    4. In the same case, the dryer is slightly better than the cold dryer in stability and effect, just because it needs to consume a certain amount of regeneration gas. The performance requirements of mechanical equipment, installation environment and required dryness, use and maintenance costs are comprehensively weighed, and the advantages and disadvantages are analyzed for selection.
    Future development of dryer:
    1. Deeply study the drying mechanism and drying characteristics of materials, master the improvement and continuous development of dryer under the optimal operating conditions for different materials, such as: automatic control technology of dryer to ensure the realization of the optimal operating conditions; large-scale equipment, high strength, high economy and improvement of adaptability to raw materials and product quality.
    2. Further research and develop new efficient and special dryer, such as combined dryer, microwave dryer and far infrared dryer.
    3. Environmental protection, energy conservation and comprehensive utilization of energy, such as adopting various joint heating methods, transplanting heat pump and heat pipe technology, developing solar dryer, etc.; improving environmental protection measures of dryer to reduce the leakage of dust and exhaust gas, etc., will also be the direction of in-depth research.
