3)opening ratio of tower plate塔板开孔率
1.The quality of scrubbed gas accords with requirements after the develop- ment of the design of water scrubber for use in the syntheis of oxalic acid now in our coun- try,the methods are;increasing the water quantity to 50m~3/h,enlarging the opening ratio of tower plate to 19.对目前国内合成法生产草酸所用水洗塔,采用加大水量到50m~3/h,提高塔板开孔率到19。
4)open annulus distributed holes开环分布孔
1.A new process method,using open annulus distributed holes in place of ring trench as the lateral oxidation windows,is reported to fabricate vertical-cavity surface emitting laser(VCSEL).采用一种新工艺制作了垂直腔面发射激光器(VCSEL),即用开环分布孔取代以往的环形沟道作为氧化物限制技术的注入窗口。
5)wide bore distribution plate大孔分布板
1.The short abrasive resistant tube on the wide bore distribution plate in regenerator of 1000kt/a heavy oil FCC unit of the refinery of Daqing Petrochemical Branch is synthesized by 0Cr18Ni9 sleeve with a short ceramic tube as an abrasive-resistant internal lining.中国石油大庆石化分公司炼油厂1000kt/a重油催化裂化装置再生器大孔分布板上的耐磨短管,由0Cr18Ni9套管内衬陶瓷耐磨短管复合而成。
6)tilted-hole distributor斜孔分布板
1.The experimental results show that tilted-hole distributor can help to finish fluidization of inert particles, because it produces air rotation.实验结果表明 :气体分布板为斜孔时所造成的旋转气流有助于惰性粒子正常流化状态的产生 ;与直孔分布板干燥器相比 ,斜孔分布板干燥器更有利于传质性能的提高 ,但孔板压降较
