選擇工業(yè)干燥設(shè)備要考慮的因素-統(tǒng)一干燥

選擇工業(yè)干燥設(shè)備要考慮的因素

由于工業(yè)烘干機(jī)是一個(gè)重大的資本投資，任何組織，是值得仔細(xì)選擇和測試設(shè)備。幾十年來，可以測量機(jī)的生命，所以選用低效率的設(shè)備可以有一個(gè)長期的經(jīng)濟(jì)健康狀況的影響，里面的設(shè)施。干燥設(shè)備的選擇主要是一項(xiàng)練習(xí)，即知識，經(jīng)驗(yàn)和科學(xué)都扮演著重要的角色。由于干燥過程中的復(fù)雜性，許多因素需要考慮并稱重。

在選擇工業(yè)烘干機(jī)，干燥的需要進(jìn)行了初步分析。問您的材料，生產(chǎn)和^終產(chǎn)品質(zhì)量的要求，和你的工廠的問題。

材料：材料的物理特性時(shí)，濕的或干的是什么？的粒度分布是什么？有毒，易燃，腐蝕性或磨損性的材料嗎？

干燥要求：材料中的水分結(jié)合（化學(xué)被困在里面的粒子），綁定（未連接到的顆粒，也稱為游離水分）或兩者？材料的初始和^終的水分含量是什么？什么是允許的^高干燥溫度，可能我的材料干燥時(shí)間嗎？什么是干燥：干燥溫度波動干燥過程的中途嗎？

生產(chǎn)要求：材料是否需要批量或連續(xù)處理？多少數(shù)量的材料必須干燥機(jī)每小時(shí)處理？什么樣的保留時(shí)間，實(shí)現(xiàn)高品質(zhì)的^終產(chǎn)品？干燥前后的過程將如何影響我的機(jī)選擇？

^終產(chǎn)品的質(zhì)量要求：材料的收縮，降低overdry或在干燥過程中受到污染？其^終含水率是如何統(tǒng)一？^終產(chǎn)品的溫度和體積密度是什么？將干燥后的材料給灰塵或需要溶劑回收嗎？

植物：有多少空間是在工廠嗎？如何溫暖，濕潤和清潔工廠的空氣嗎？什么樣的燃料和動力源，濕飼料來源和排氣的氣體噴出口，可在工廠中？什么級別的噪聲，振動，灰塵和熱量的損失，允許在工廠根據(jù)當(dāng)?shù)胤謪^(qū)和環(huán)保法規(guī)嗎？

通過回答這些問題，你會排除許多機(jī)，為您的應(yīng)用程序是不適合的。例如，物理或處理的材料的特性將消除一些干衣機(jī)。蒸汽管回轉(zhuǎn)干燥機(jī)是潮濕的，有粘性材料，如云母不是一個(gè)好的選擇。烘干機(jī)將材料旋轉(zhuǎn)和滾動，這種消極輸送不能移動粘性物質(zhì)的入口區(qū)域前對血管壁和蒸汽管道的蛋糕。螺旋輸送器或間接的多圓盤式干燥機(jī)是更好的選擇。任一個(gè)單元提供正位移，可以快速移動云母遠(yuǎn)離入口朝向出口。

其次，考慮足跡機(jī)，以滿足您的要求或所需的占地空間。排除任何機(jī)，不符合現(xiàn)有的空間，或?qū)⑿枰嘿F的工廠改建，擴(kuò)建。剩余的候選人的資本和經(jīng)營成本和性能進(jìn)行比較。

如果選擇一個(gè)高性能的機(jī)升級您現(xiàn)有的干燥過程中，考慮現(xiàn)有的配套項(xiàng)目，如存儲和接收設(shè)備，輸送機(jī)和污染控制設(shè)備，可以處理新機(jī)的容量增加。

一旦干燥機(jī)的選擇已經(jīng)縮小，與你的材料測試機(jī)，根據(jù)您的作業(yè)條件。

機(jī)測試，可進(jìn)行中試試驗(yàn)研究實(shí)驗(yàn)室設(shè)施，并應(yīng)建立：

為你的材料的^佳操作條件 每個(gè)機(jī)處理材料的物理特性 干燥后的材料的質(zhì)量和特色 適當(dāng)?shù)臋C(jī)大小 基于這些結(jié)果，烘干機(jī)生產(chǎn)廠家Heyl和帕特森等設(shè)備，將滿足您的干燥需求制定詳細(xì)的建議。建議在手，你可以選擇一個(gè)機(jī)和干燥選項(xiàng)。討論的因素包括機(jī)的安裝和運(yùn)營成本，本機(jī)的操作和維護(hù)要求。

Factors to Consider in Selecting Industrial Drying Equipment

Because an industrial dryer is a major capital investment for any organization, it pays to select and test the unit carefully.  Dryer life can be measured in decades, so the selection of inefficient equipment can have a long-term impact on the economic health of the facility that houses it.  The selection of drying equipment is predominantly an exercise in which knowledge, experience and science all play important roles.  Because of the complexity of the drying process, many factors need to be considered and weighed.

Before choosing an industrial dryer, conduct a preliminary analysis of your drying needs.  Ask questions about your material, the production and final product quality requirements, and your plant.

Material:  What are the material's physical characteristics when wet or dry?  What is the particle size distribution?  Is the material toxic, flammable, corrosive or abrasive?

Drying requirements:  Is the material's moisture bound (chemically trapped inside the particles), unbound (not attached to the particles, also called free moisture) or both?  What are the material's initial and final moisture contents?  What are the maximum permissible drying temperature and probably drying time for my material?  What is the drying curve: Will the drying temperature need to fluctuate midway through the drying process?

Production requirements:  Does the material need to be batch or continuously processed?  What quantity of material must the dryer handle per hour?  What retention time will achieve a high-quality final product?  How will the processes before and after drying affect my dryer choice?

Final product quality requirements:  Can the material shrink, degrade, overdry or become contaminated during drying?  How uniform must its final moisture content be?  What should the final product temperature and bulk density be?  Will the dried material give off dust or require solvent recovery?

Plant:  How much space is available in the plant?  How warm, humid and clean in the plant air?  What fuel and power sources, wet feed sources and exhaust gas outlets are available in the plant?  What levels of noise, vibration, dust and heat loss are permissible in the plant according to local zoning and environmental regulations?

By answering these questions, you will rule out many dryers that are not suitable for your application.  For instance, a material's physical or handling characteristics will eliminate some dryers.  A steam-tube rotary dryer is not a good choice for a wet, sticky material such as mica.  The dryer moves material by rotating and rolling it, and such passive conveying can't move a sticky material out of the inlet area before it cakes on the vessel wall and steam tubes.  A screw conveyor or indirect multiple disc dryer is a better choice.  Either unit provides positive displacement that can quickly move the mica away from the inlet and toward the outlet.

Next, consider the footprint or required floor space of the remaining dryers that meet your requirements.  Rule out any dryer that does not fit the existing space or would require a costly plant renovation or expansion.  Compare the capital and operating costs and performance of the remaining candidates.

If selecting a high-performance dryer to upgrade your existing drying process, consider whether existing ancillary items such as storage and receiving equipment, conveyors and pollution control equipment can handle the new dryer's increased capacity.

Once the field of dryer choices has been narrowed, test the dryers with your material under your operating conditions.

Dryer tests can be conducted in a pilot plant lab facility, and should establish:

The optimal operating conditions for your material How well each dryer handles the material's physical characteristics The material's quality and characteristics after drying The appropriate dryer size Based on these results, a dryer manufacturer such as Heyl & Patterson can develop detailed recommendations for equipment that will meet your drying needs.  With recommendations in hand, you can select a dryer and drying options.  Factors to discuss include the dryer's installation and operating costs, the dryer's operation and maintenance requirements.
