一、技术简介:导向筛板是在普通筛板的基础上进一部改进的一种塔板。随着市场需求量的增加,聚乙烯醇(PVA)生产厂需要扩大生产规模,增加产量。但设备,尤其是塔类设备处理量小、分离效果差、能耗高、物料损耗大、操作困难,经常出现中途被迫停车的现象,严重制约了生产的正常连续运转。若设计新塔,工期长、费用高、不切合企业现状。我校将导向筛板及计算机模拟优化技术成功的应用在聚乙烯醇的生产中,改造了乙炔综合洗涤塔、精馏一塔、精馏二塔、回收二塔、聚合一塔、聚合二塔、聚合三塔等七个塔。本技术在不
First, the technical profile: Guide Sieve is an ordinary plate based on an improved version of a plate. With the increase in market demand, polyvinyl alcohol (PVA) production plants need to expand the scale of production and increase production. However, the equipment, especially the tower equipment, has the advantages of small processing capacity, poor separation effect, high energy consumption, large material loss, difficult operation and frequent forced parking, which seriously hinders the normal continuous operation of production. If the design of a new tower, long duration, high cost, does not meet the business status quo. Our school will guide the sieve and computer simulation optimization technology successfully applied in the production of polyvinyl alcohol, modified acetylene integrated scrubber, distillation tower, distillation tower, recovery tower, polymerization tower, polymerization tower , Three towers and other seven towers. This technology is not
