水力喷射器与真空泵谁好

常见的抽真空装置有：水力喷射器、蒸汽式喷射泵、往复泵和离心式真空泵（水环式真空泵、旋片式真空泵）。

水力式喷射器工作时借助离心泵的动力将水压入喷嘴，由于喷嘴处面积突然变小，水流以高速射入混合室及扩散室，喷嘴出口处便形成负压，二次蒸汽不断吸入，并与冷水进行热交换，二次蒸汽凝结为冷凝水，同时夹带不凝性气体，随冷水一起排出，即可起到抽真空的作用。同时起到冷凝作用。

蒸汽式喷射器：工作原理与水力式喷射器很类似，只是蒸汽式喷射器喷出的是蒸汽，所以它可以起到抽真空的作用，但是不能冷凝，不过它抽真空的能力大于水力喷射器。

往复式真空泵是通过活塞往复运动把冷凝器内的冷却水及不凝结气体一起同时排出，保证系统的真空。

水环式真空泵是利用离心力的作用，将水甩到工作室内壁上形成一个水环，水环内部表面与轮壳相切，沿箭头方向旋转的叶轮在前半转中，水环的内表面逐渐离开轮壳，片间空隙逐渐扩大，被抽气体从镰刀形吸气口中被吸入而形成真空。后半转中，水环的内表面逐渐与轮壳靠近，片间空隙逐渐缩小，被抽气体被压缩并从另一边的镰刀形排气口中排出。叶轮每转一周，叶片间容积即改变一次，叶片间的水就像活塞一样反复运动，也就连续不断地抽吸和排出气体。

减压冷浸罐工作原理是：采用自流或真空抽取的方式，把物料送入浓缩罐内，然后利用夹套通蒸汽进行加热，最后成品从受液槽内取得。减压冷浸罐适用于中药、西药、淀粉糖、食乳品等物料浓缩与工业有机溶剂（如酒精）的回收，适用于批量小、品种多的热敏性物料的低温真空浓缩。装置由立管式加热器、浓缩器、冷凝器及管道阀门等组成，真空系统可与其它设备配用水力喷射器或真空泵。

三效浓缩器在一、二效分离器内隔板隔出顶部与内腔相通的蒸汽腔，蒸汽腔底部接直管与下一级加热器连接，为二次或三次蒸汽管。蒸汽从分离器顶部进入蒸汽腔，直接进入下一级加热器。因蒸汽腔的横截面比一般蒸汽管大得多，直管通入下一级加热器无折转，距离近，大大降低蒸汽阻力，增加流量，提高分离效率。且因蒸汽腔是位于分离器内，减少了引出蒸汽的热量损失。一效加热器的疏水管通入分离器的冷凝室，冷凝水从其下排出，避免了蒸汽损失，也解决了疏水器的噪声和污染。下联管前端的清洗手孔，便于清洗加热器底部边角的残留物。各分离器有独立进料口，便于观察和控制进料流量。三组加热器和分离器按扇形排列布置，缩短了设备总长度，便于操作。

多效蒸发流程是由多个蒸发器组合后的蒸发操作过程。多效蒸发时要求后效的操作压强和溶液的沸点均较前效低，引入前效的二次蒸汽作为后效的加热介质，即后效的加热室成为前效二次蒸汽的冷凝器，仅第一效需要消耗生蒸汽。一般多效蒸发的末效或后几效总是在真空下操作，由于各效（除末效外）二次蒸汽都作为下一效的加热蒸汽，故提高了生蒸汽的利用率，即经济性。需要强调的是蒸发量与传热量成正比，多效蒸发并没有提高蒸发量，而只是节约了加热蒸汽，其代价是设备投资增加。在相同的操作条件下，多效蒸发器的生产能力并不比传热面积与其中一个效相等的单效蒸发器的生产能力大。特别应注意那种认为多效蒸发器的生产能力是单效蒸发器的若干倍的观点是错误的。

根据给蒸发器加入原料的方式，可分为并流加料、逆流加料和平流加料三种蒸发流程。下面以三效为例分别介绍：

1. 并流蒸发流程

并流三效蒸发流程中，溶液和加热蒸汽的流向相同，都是从第一效开始按顺序流到第三效后结束。其中加热蒸汽分两种，第一效是生蒸汽，即由其他蒸汽发生器产生的蒸汽，第二效和第三效的蒸汽是二次蒸汽，第一效蒸发产生的蒸汽是第二效蒸发的加热蒸汽，第二效蒸发产生的二次蒸汽是第三效蒸发的加热蒸汽。原料液进入第一效浓缩后由底部排出，并依次进入第二效、第三效，在第二效和第三效被连续浓缩。完成液由第三效底部排出。

并流加料法的优点有利用各效间的压力差输送料液；因前效温度和压力高于后效可以不设预热器；辅助设备少，流程紧凑，温度损失小；操作简便，工艺稳定，设备维修量少。其缺点是：后效温度降低后，溶液黏度逐效增大，降低了传热系数，需要更大的传热面积。

2. 逆流加料流程

在逆流加料流程中，料液与蒸汽走向相反。料液从末效加入蒸发浓缩后，用泵将浓缩液送入前一效直至末效，得到完成液；生蒸汽从第一效加入后经放热冷凝成液体，产生的二次蒸汽进入第二效，在对料液加热后冷凝成液体，第二效产生的二次蒸汽进入第三效对原料液加热，释放热量后冷凝成液体排出。

逆流加料流程中，因随浓缩液浓度增大而温度逐效升高，所以各效的黏度相差较小，传热系数大致相同；完成液排出温度较高，可在减压下进一步闪蒸浓缩。其缺点是：辅助设备多，需用泵输送原料液；因各效在低于沸点下进料，故必须设置预热器。能量消耗大也是其缺点。逆流加料流程主要应用于黏度较大的液体的浓缩。

3. 平流加料流程

在平流蒸发流程中，原料液分别加入到各效蒸发器中，完成液分别从各效引出，蒸汽流向是从第一效进生蒸汽，产生的二次蒸汽进入第二效并释放热量后冷凝成液体，第二效产生的二次蒸汽进入第三效，在第三效释放热量后冷凝成液体而排出。此法主要用于黏度大、易结晶的场合，也可以用于两种或两种以上不同液体的同时蒸发过程。

多效蒸发流程只在第一效使用了生蒸汽，故节约了生蒸汽的需要量，有效地利用了二次蒸气中的热量，降低了生产成本，提高了经济效益。在实际生产中，还可根据具体情况，将以上基本流程进行组合，设计出更适应生产需要的多效流程。

三效蒸发的原理是：从一效进入的蒸汽被利用了三次，这样提高了蒸汽的加热效率也就是热经济，多效蒸发的实质就是减少蒸汽的消耗
