前言分离过程是化工生产工艺中的重要组成部分,塔设备是主要的化工分离设备。随着化工生产的发展,高效率、大通量、低能耗分离技术越来越受到人们的重视,高效导向筛板就是适应这种趋势而开发出来的新型塔板。我国从20世纪70年代开始对导向筛板进行系统研究,并将其推向全国[1]。目前,高效导向筛板已在化工、化纤、石化、轻工等行业广泛的应用。
Preface The separation process is an important part of chemical production process, tower equipment is the main chemical separation equipment. With the development of chemical production, more and more attention has been paid to high-efficiency, high-throughput and low-power separation technologies. Highly-oriented sieve trays are new trays developed to meet this trend. China started from the 1970s to conduct a systematic study of the guide plate, and push it to the whole country [1]. At present, the high efficiency of the guide plate has been in chemical, chemical fiber, petrochemical, light industry and other industries a wide range of applications.
