流筛板 meaning in English

flow screen

The test was made on the compound tray , dual flow tray , sieve tray and valve tray for mass transfer efficiency with in - diameter 300 mm column using ethanoi and water system
在直径300mm的精馏塔内，以乙醇-水为介质，进行了复合塔板、穿流筛板、筛板和浮阀塔板的传质效率的研究。
The experiment ' s results show that the total and plat efficiency of the compound tray is over 100 % , the highest efficiency can be up to 122 % within the range of f factor i ~ 2 . 5m / s ( kg / m3 ) i / 2 , it is far higher than the efficiency of dual flow tray , sieve tray and valve tray
实验表明，复合塔的全塔效率和单板效率在f因子1 2 . 5m s ( kg m3 ) ” ’范围内，可超过100 ，最高效率达122 ，远高于穿流筛板、筛板和浮阀塔板的效率。
The compound tray researched in this paper consists of dual - flow tray and 50 - 1 ^ omm high structural packing which is directly put under the dual - flow tray . it has three mass transfer sections that is the foam section on the tray , the film section in the packing layer and the shower section under the packing , so it has very high mass transfer efficiency
本文研究的复合塔板是在穿流筛板之下紧贴一层50 150mm的规整填料所构成，它有三个传质区，即塔板上的泡沫区、填料层内的液膜区以及填料层下的淋降区，因此，具有很高的传质效率。
