每種干燥裝置都有其特定的適用范圍,而每種物料都可找到若干種能滿足基本要求的干燥裝置,但適合的只能有一種。如選型不當,用戶除了要承擔不必要的一次性高昂采購成本外,還要在整個使用期內(nèi)付出沉重的代價,諸如效率低、耗能高、運行成本高、產(chǎn)品質量差、甚裝置根本不能正常運行等等。
Each drying device has its specific scope of application, and several drying devices that can meet the basic requirements can be found for each material, but only one is suitable. In case of improper selection, users not only have to bear the unnecessary one-time high procurement cost, but also pay a heavy price in the whole service life, such as low efficiency, high energy consumption, high operation cost, poor product quality, and even the device can not operate normally at all.
以下是干燥裝置選型的一般原則,很難說哪一項或哪幾項是重要的,理想的選型必須根據(jù)自己的條件有所側重,有時折中是必要的。
The following are the general principles of type selection of drying device. It is difficult to say which one or several items are important. The ideal type selection must focus on its own conditions, and sometimes compromise is necessary.
1.適用性-------干燥裝置必須能適用于特定物料,且滿足物料干燥的基本使用要求,包括能很好的處理物料(給進、輸送、流態(tài)化、分散、傳熱、排出等),并能滿足處理量、脫水量、產(chǎn)品質量等方面的基本要求。
1. Applicability ---- firstly, the drying device must be applicable to specific materials and meet the basic use requirements of material drying, including good treatment of materials (feeding, conveying, fluidization, dispersion, heat transfer, discharge, etc.), and meet the basic requirements of treatment capacity, dehydration, product quality, etc.
2.干燥速率高---僅就干燥速率看,對流干燥時物料高度分散在熱空氣中,臨界含水率低,干燥速度快,而且同是對流干燥,干燥方法不同臨界含水率也不同,因而干燥速率也不同。
2. High drying rate - only in terms of drying rate, during convective drying, the materials are highly dispersed in hot air, with low critical moisture content and fast drying speed. Moreover, with the same convective drying, the drying methods are different, and the critical moisture content is also different, so the drying rate is also different.
3.耗能低-------不同干燥方法耗能指標不同,一般傳導式干燥的熱效率理論上可達100%,對流式干燥只能70%左右。
3. Low energy consumption ---- different drying methods have different energy consumption indicators. Generally, the thermal efficiency of conduction drying can reach 100% in theory, and that of convection drying can only be about 70%.
4.節(jié)省投資-----完成同樣功能的干燥裝置,有時其造價相差懸殊,應擇其低者選用。
4. Save investment ---- sometimes the cost of drying devices with the same function varies greatly, and the lower one should be selected.
5.運行成本低---設備折舊、耗能、人工費、維修費,備件費...等運行費用要盡量低廉。
5. Low operation cost - equipment depreciation, energy consumption, labor cost, maintenance cost, spare parts cost... And other operation costs shall be as low as possible.
6.優(yōu)先選擇結構簡單、備品備件供應充足、可靠性高、壽命長的干燥裝置。
6. The drying device with simple structure, sufficient supply of spare parts, high reliability and long service life shall be preferred.
7.符合要求,工作條件好,安 全性高。
7. Meet environmental protection requirements, good working conditions and high safety.
8.選型前能做出物料的干燥實驗,深入了解類似物料已經(jīng)使用的干燥裝置(優(yōu)缺點),往往對恰當選型有幫助。
8. Be able to make drying experiments of materials before type selection, and deeply understand the drying devices (advantages and disadvantages) used for similar materials, which is often helpful for proper type selection.
