立体连续传质塔板及其在精馏中的应用

Characteristics of spraying tridimensional successive mass transferring-tray and its application in distillation technology

在新型垂直筛板(New-VST)基础上进行帽罩结构的改进,开发了一种新的喷射型立体连续传质塔板——梯矩形立体连续传质塔板(LLCT),介绍了该塔板结构、操作工况、技术特性及其在聚氯乙烯、甲醇等行业精馏塔技术改造应用的实例。简要介绍了在梯矩形立体连续传质塔板基础上进一步发展起来的国家发明专利技术——超高通量、超高操作弹性的喷射型立体连续传质塔板。

Based on the new-vertical-sieve-tray, some reform on cap structure is made to develop a new spraying tridimensional successive mass transferring-tray（ LLC-Tray）. The structure,operating conditions and technical characteristics of LLC-Tray are introduced,and its application of LLC-Tray inthe production of PVC, methanol industry and so on is also shown in this paper. The new type of spraying tridimensional successive mass transferring-tray which is developed based on LLC-Tray, which is a piece of national inventive patent, has the advantages of super high flux and operating flexibility.
