They stretch out forefinger and middle finger (of one hand) to shape a "V", which means victory.

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
