1976年5月网孔塔板在抚顺石油二厂φ4,500减压塔上应用,同年11月上海化工学院与石油二厂协作着手试验室冷模试验,1978年10月石油二厂又在催化裂化装置φ3,800常压分馏塔上应用,都显示出网孔塔板处理量大、压降小、效率高和重量轻的优点。根据两年多冷模及工业性试验所取得的数据,关联出了一套设计计算所需的基本公式。为便于广泛应用,今初步提出如 In May 1976, the mesh tray was applied to the φ4,500 vacuum tower of Fushun Petrochemical Plant No.2. In November of the same year, Shanghai Institute of Chemical Technology and Petroleum Plant No.2 cooperated with the laboratory cold mold test. In October 1978, Cracking unit φ3,800 atmospheric distillation tower applications, have shown that the mesh tray handling capacity, pressure drop, high efficiency and light weight advantages. Based on the data obtained from more than two years of cold molds and industrial tests, a set of basic formulas for calculating the design requirements are associated. For the convenience of wide application, this preliminary proposal is as follows
