Unit13Unit Operations in Chemical Engineering 第十三单元化学工程中的单元操作化学工程由不同顺序的步骤组成，这些步骤的原理与被操作的物料以及该特殊体系的其他特征无关。

在设计一个过程中，如果（研究）步骤得到认可，那么所用每一步骤可以分别进行研究。

有些步骤为化学反应，而其他步骤为物理变化。

化学工程的可变通性（versatility）源于将一复杂过程的分解为单个的物理步骤（叫做单元操作）和化学反应的实践。

化学工程中单元操作的概念基于这种哲学观点：各种不同顺序的步骤可以减少为简单的操作或反应。

不管所处理的物料如何，这些简单的操作或反应基本原理（fundamentals）是相同的。

这一原理，在美国化学工业发展期间先驱者来说是明显的，首先由 A.D.Lttle于1915年明确提出：任何化学过程，不管所进行的规模如何，均可分解为（be resolved into）一系列的相同的单元操作，如：粉碎、混合、加热、烘烤、吸收、压缩、沉淀、结晶、过滤、溶解、电解等等。

这些基本单元操作（的数目）为数不多，任何特殊的过程中包含其中的几种。

化学工程的复杂性来自于条件（温度、压力等等）的多样性，在这些条件下，单元操作以不同的过程进行，同时其复杂性来自于限制条件，如由反应物质的物化特征所规定的结构材料和设备的设计。

最初列出的单元操作，引用的是上述的十二种操作，不是所有的操作都可视为单元操作。

从那时起，确定了其他单元操作，过去确定的速度适中，但是近来速度加快。

流体流动、传热、蒸馏、润湿、气体吸收、沉降、分粒、搅拌以及离心得到了认可。

近年来，对新技术的不断理解以及古老但很少使用的分离技术的采用，引起了分离、处理操作或生产过程步骤上的数量不断增加，在多种操作中，这些操作步骤在使用时不要大的改变。

这就是“单元操作”这个术语的基础，此基础为我们提供了一系列的技术。

1.单元操作的分类（1）流体流动流体流动所涉及到的是确定任何流体的从一位置到另一位置的流动或输送的原理。

Spur GearsGears , defined as toothed members transmitting rotary motion from one shaft to another , are among the oldest devices and inventions of man . In about 2600 B.C. , the Chinese are known to have used a chariot incorporating a complex series of gears . Aristotle , in the fourth century B.C. , wrote of gears as if they were commonplace . In the fifteenth century A.D. , Leonardo da Vinci designed a multitude of devices incorporating many kinds of gears .齿轮，在最古老的设备和发明人中，被定义为通过轮齿将旋转运动从一根轴传递到另一根轴，大约在公元前2600年，中国人就知道用战车组成一系列复杂的齿轮系。

西元前四世纪，亚里士多德记述了齿轮就好像是他们司空见惯的一样。

在十五世纪，达芬奇设计了大量的包含各种各样齿轮的设备。

Among the various means of mechanical power transmission (including primarily gears , belts , and chains ) , gears are generally the most rugged and durable . Their power transmission efficiency is as high as 98 percent . On the other hand , gears are usually more costly than chains and belts . As would be expected , gear manufacturing costs increase sharply with increased precision -- as required for the combination of high speeds and heavy loads , and for low noise levels . ( Standard tolerances for various degrees of manufacturing precision have been established by the AGMA , American Gear Manufacturers Association. )在众多的机械传动方式中（包括齿轮传动，带传动，链传动），一般来说，齿轮是最经久耐用的，它的能量传递效率高达98%。

The micrometer screw gauge also uses an auxiliary scale (measuring hundredths of a millimeter) which is marked on a rotary thimble. Basically it is a screw with an accurately constant pitch. The micrometers in our laboratory have a pitch of 0.50 mm. The rotating thimble is subdivided into 50 equal divisions. The thimble passes through a frame that carries a millimetre scale graduated to 0.5 mm. The jaws can be adjusted by rotating the thimble using the small ratchet knob. The thimble must be rotated through two revolutions to open the jaws by 1 mm. Here is a useful applet to learn how to use the micrometer screw gauge (Figure 1-19).Figure 1-19 The micrometer screw gaugeIn order to measure an object, the object is placed between the jaws and the thimble is rotated using the ratchet until the object is secured. Note that the ratchet knob must be used to secure the object firmly between the jaws, otherwise the instrument could be damaged or give an inconsistent reading.Note that an additional half scale division (0.5 mm) must be included if the mark below the main scale is visible between the thimble and the main scale division on the sleeve. The remaining two significant figures (hundredths of a millimeter) are taken directly from the thimble opposite the main scale.In Figure 1-20 the last graduation visible to the left of the thimble is 7 mm and the thimble lines up with the main scale at 38 hundredths of a millimeter (0.38 mm); therefore the reading is 7.38 mm.In Figure 1-21 the last graduation visible to the left of the thimble is 7.5 mm; therefore the reading is 7.5 mm plus the thimble reading of 0.22 mm, giving 7.72 mm.Figure 1-20 The reading is 7.38mm Figure 1-21 The reading is 7.27mm In Figure 1-22 the main scale reading is 3 mm while the reading on the drum is 0.46 mm; therefore, the reading is 3.46 mm.In Figure 1-23 the 0.5 mm division is visible below the main scale; therefore the reading is 3.5 mm + 0.06 mm = 3.56 mm.Figure 1-22 The reading is 3.46mm Figure 1-23 The reading is 3.56mm Try the following bg yourselfFigure 1-24 Figure 1-25 Figure 1-26A: Do exercise 1, 2, 3, 4 and 7.AssignmentB: Ask students to collect some external machine tools.《机电一体化专业英语》授课计划_ _______ 学院___ 专业班20 －20 学年第学期授课时间：第周Key Points unit.2.

To get the work properly centered, close the jaws until they just touch the surface of the work, then rotate the work-piece by hand in the jaws to seat it; then tighten the jaws (Figure 2-17). Beginning the Facing CutUse the pound handwheel to advance the tip of the tool until it just touches the end of the work-piece. Use the cross feed crank to back off the tool until it is beyond the diameter of the work-piece. Turn the lathe on and adjust the speed to a few hundred RPM — setting of the speed control knob. Now slowly advance the cross feed hand-wheel to move the tool towards the work-piece. When the tool touches the work-piece it should start to remove metal from the end (Figure 2-18). Continue advancing the tool until it reaches the center of the work-piece and then crank the tool back in the opposite direction (towards you) until it is back past the edge of the work-piece (Figure 2-19).Figure 2-18 Figure 2-19 Since we started with the tool just touching the end of the work-piece, you probably removed very little metal on this pass. This is a good idea until you get used to how aggressively you can remove metal without stalling the lathe.The Roughing CutUse the pound crank to advance the tool towards the chuck about 0.010". If the pound is set at a 90 degrees to the cross slide (which is how I usually set mine) then each division you turn the crank will advance the tool 0.001 (one-thousandth of an inch) toward the chuck.If the pound is set at some other angle, say 30 degrees, to the cross slide, then it will advance the tool less than 0.001 for each division. The exact amount is determined by the trigonometric sine of the angle. Here’s a picture of the first pass of a facing operation (Figure 2-20).Cutting on the Return PassIf you crank the tool back towards you after it reaches the center of the work-piece you will notice that it removes a small amount of metal on the return pass. This is because the surface is not perfectly smooth and it is removing metal from the high spots. If you need to remove a lot of metal, to reduce the work-piece to a specific length, for example, you can take advantage of this return cut to remove more metal on each pass by advancing the tool a small ways into the work-piece on the return pass. Since the tool must plunge into the face of the work-piece, this works best with a fairly sharp pointed tool.The Finishing CutDepending on how rough the end of the work-piece was to begin with and how large the diameter is, you may need to make three or more passes to get a nice smooth finish across the face. These initial passes are called roughing passes and remove a relatively large amount of metal.When you get the face pretty smooth you can make a final finishing cut to remove just 0.001 to 0.003" of metal and get a nice smooth surface. Figure 2-21 shows removingabout 0.002" of metal at around 1 000 RPM. Figure 2-22 shows the finished face of thework-piece.　Figure 2-21 Figure 2-22Figure 2-23 shows what happens if the tip of your cutting tool is below the center line of the lathe — a little nub is left at the center of the work-piece. The same thing happens ifthe tool is too high but the nub will have more of a cone shape in that case. If the tool is toolow, place a suitable thickness of shim stock underneath the tool in the tool holder. If it’s toohigh, grind the top down a few thous.Filing the EdgeFacing operations leave a rather sharp edge on the end of the work-piece. It’s a good idea to smooth this edge down with a file to give it a nice chamfer and to avoid cuttingyourself on it. With the lathe running at fairly low speed, bring a smooth cut file up to theend of the work-piece at a 45 degree angle and apply a little pressure to the file. Figure2-24: Right — left hand holding tang end of file. Figure 2-25: Wrong — left hand reachingover spinning chuck!Figure 2-23 Figure 2-24Figure 2-26 shows the finished surface and beveled edge. This is what a good facing cut should look like: smooth even surface with no raised bump in the center.　Lay anaccurate straight edge across the surface of the face and you should not be able to seeany light under the edge. If you detect a slight convex shape, the carriage may be movingback away from the headstock during the cut.Figure 2-25 Figure 2-26A: Do exercise 1, 2, 3, 4 and 7.AssignmentB: Ask students to collect some external machine tools.《机电一体化专业英语》授课计划_ _______ 学院___ 专业班20 －20 学年第学期授课时间：第周教学难点Difficult Points 1.

1.With low-power machinery or vehicles the operator can usually apply sufficient force through a simple mechanical linkage from the pedle or handle to the stationary part of the brake. In many cases, however, this force must be multiplied by using an elaborate braking system（P5.）用低能机器或传力工具，操作者通过向踏板或把手的一个简单机械连接构件作用足够的力量到车闸固定的部分。

大多数情况，然而，用一个详细（复杂）的车闸系统使这个力量成倍增加。

2.The fundamental principle involved is the use of compressed air acting through a piston in a cylinder to set block brakes on the wheels. The action is simultaneous on the wheels of all thecars in the train. The compressed air is carried through a strong hose from car to car withcouplings between cars; its release to all the separate block brake units, at the same time, is controlled by the engineer. (Braking Systems)（ P5）相关的基本原理是使用压缩气体，通过气缸内的活塞将闸块压在车轮起作用。
