急用啊 谢谢各位！
(5)板式塔对于液体冷却更容易，更适于处理有固体渣和高粘度的料液及高压情况
下的蒸馏。规整填料造价较高，也是应该考虑的。
由以上分析，可以清楚地看到两种塔各有其优缺点，在应用的时候，要认真考虑。板
式塔的设计已形成了一套比较成熟的方法，并广为应用，而规整填料塔，还没有一种为大家公认的设计方法，这也正是本文在这方面希望进行的工作。
从所周知，设计塔设备最关键的是设计出满足生产要求的塔径、塔高、压降，同时在设计过程中亦考虑其中的流体力学性能，液体泄流量，流体分布等等。本文通过大量
的文献调研，针对填料塔的性能，对塔内压降、传质及液泛点等找出一种优化设计的方法。

是：(5) the plate tower is easier regarding the liquid cooling, issuitable for to process has the solid dregs and the high viscositymaterial fluid and the high-pressured situation
Next distillation. The neat padding construction cost ishigher, also is should consider.
Analyzes by above, may clearly see respectively has its good and badpoints to two kind of towers, is applying, must earnestly consider.Board
The type tower design has formed set of quite mature methods,and widely applies, but neat absorption chamber, but also does nothave one kind for everybody recognition design method, this also isprecisely this article in this aspect hoped carries on work.
From knowns by everybody, the design tower equipment most essential isdesigns satisfies the production request the tower diameter, the toweris high, the pressure drop, simultaneously in the design process alsoconsidered hydromechanics performance, the liquid releases the currentcapacity, fluid distribution and so on. This article passes massively
The literature investigation and study, in view of theabsorption chamber performance, to the tower 内压降, the masstransfer and the fluid flooding point and so on discovers one kind ofoptimized design the method.
应该没错了
