译文:对于连续的干燥,冷却,焙烧和热处理的固体颗粒,西蒙转筒干燥器提供了简单的解决方案。能够处理大吨位的吞吐量,并能够承受年的运作,将停机时间降至^低,西蒙回转烘干机满足所有的要求,世界上主要的材料处理器每365天每天24小时的严格要求。

干燥,焙烧或热处理来实现,通过被加工的材料通过它也通过的电流的热空气通过一个旋转的缸体。升降器或嵌合气缸升降机和级联的材料通过热空气流的内表面飞行。无论是在相同的方向上的材料(顺流),或在相反的方向(逆流)的空气流可被引导通过气缸。顺流系统中使用普遍的干燥应用。逆流系统更高效的能量输入,但会引起产品的高的温度,与相关联的处理问题。

同样,冷却可通过的材料,可以通过该流动的电流的冷空气或外部冷却水浴或喷雾喷嘴的装置通过一个旋转筒冷却通过。

干燥空气可以被加热物,也可以直接由石油,天然气或固体燃料的燃烧器的装置,或间接地通过使用蒸汽或其它加热介质的合适的热交换器。干燥温度低于100℃的温度高达700摄氏度的范围

任何干燥操作的废气流从不可避免地包括一个显着量的微粒。此微粒结转可能被收集的气体通过通过高效旋风分离器或袋式过滤器或湿式涤气器或任何或所有这些的组合,这取决于涉及的尘埃的性质和数量。

干燥过程中的废气流从任何可能还包含相当量的废热能量。一些这种能量可以通过废气流的,合适的清洗后,热回收单元回收。这样的单元的设计不仅直接从废气中除去热量,但也可以被设计以冷凝出的水蒸汽或其它挥发物回收潜热。然后,可以从热回收单元的清洁程度暖空气输送到干燥器入口空气加热器,从而降低整体的干燥过程中的能量输入。

除了旋转式干燥机和冷却器,级联和叶片,R.Simon(烘干机)有限公司设计和制造的旋转造粒机,涂料桶,旋转式反应器,在一个标准的直径范围从1米到3.5米和更大的根据需要,配套设备,以满足个别客户的规格。

概观

R.西蒙(烘干机)有限公司设计和制造了一系列的旋转干燥器,连同多年的经验,意味着我们的机器可以选择适合您的特定应用程序。

转筒干燥器分为三大类:

旋转的级联干燥器,其中材料被提升,并通过热空气流的级联。

旋转叶片干燥器,其中热空气流通过一个'滚动'的材料床。

蒸汽管回转干燥机,材料的提升和级联通过旋转蒸汽管束 外部,所有的转筒干燥器有类似的结构,组成的嵌合用轮胎上运行的一组支撑辊,用链或直齿圆柱齿轮环驱动的旋转壳。


原文:

For the continuous drying, cooling, roasting and heat treatment of particulate solids, Simon Rotary Dryers provide the simple solution. Capable of handling large tonnage throughputs and built to withstand the rigours of 24 hours per day 365 days per year operation with minimum downtime the Simon Rotary Dryer meets all the requirements of the world's major material processors.

Drying, roasting or heat treatment is achieved by passing the material being processed through a rotating cylinder through which also passes a current of hot air. Lifters or flights fitted to the internal surface of the cylinder lift and cascade the material through the hot air stream. The air stream can be directed through the cylinder either in the same direction as the material (co-current) or in the opposite direction (counter-current). Co-current systems are used in most general drying applications. Counter-current systems are more efficient in terms of energy input but give rise to high product temperatures, with the associated handling problems.

Similarly, cooling may be effected by passing the material to be cooled through a rotating cylinder through which flows a current of cold air or which is externally cooled by means of a water bath or spray nozzles.

The drying air may be heated either directly by means of oil, gas or solid fuel burners or indirectly by means of suitable heat exchangers using steam or other heating . Drying temperatures range from below 100 deg.C up to 700 deg.C.

The exhaust gas stream from any drying operation inevitably includes a significant amount of fine particles. This fine particle carryover may be collected by passing the gases through high efficiency cyclones, or bag filter or wet scrubber or a combination of any or all of these, depending upon the nature and quantity of dust involved.

The exhaust gas stream from any drying process may also contain a substantial quantity of waste heat energy. Some of this energy may be recovered by passing the exhaust gas stream, after suitable cleaning, to a heat recovery unit. Such units are designed not only to remove heat directly from the exhaust gases but may also be designed to condense out water vapour or other volatiles to recover latent heat. Clean warm air from the heat recovery unit can then be ducted to the dryer inlet air heater thus reducing the overall energy input of the drying process.

In addition to Rotary Dryers and Coolers, of both cascade and louvre type construction, R.Simon (Dryers) Ltd. Design and manufacture Rotary Granulators, Coating Drums and Rotary Reactors, in a standard range of diameters from 1 Metre to 3.5 Metres and larger as required, with ancillary equipment to suit individual client's specifications.

Overview

R. Simon (Dryers) Limited design and manufacture a range of Rotary Dryers, which together with years of experience means that we can select the machine most suited to your particular application.

Rotary Dryers fall into three main categories:

Rotary Cascade Dryers, where material is lifted and cascaded through a hot air stream.

Rotary Louvre Dryers, where the hot air stream is passed through a 'rolling' bed of material.

Rotary Steam Tube Dryers, where material is lifted and cascaded through a rotating steam tube bundle Externally, all Rotary Dryers have a similar construction, consisting of a rotating shell fitted with tyres running on a set of support rollers, with a chain or spur gear ring drive.
