以烟台泰和新材料股份有限公司(原烟台氨纶)投资建造的舒适氨纶项目为背景,对其聚合工艺中采用的关键设备——第二反应器机械密封进行技术改进,分析其泄露产生的原因,提出了机封泄露问题解决方案,给出了改进前后机械密封结构图,对第二反应器检修和安装进行了技术规范。改造后的机械密封运转周期达到1年,大大降低了生产成本,延长了使用周期。
Based on the comfortable spandex project invested and constructed by Yantai Taihe New Material Co., Ltd. (formerly Yantai Spandex), the key equipment used in the polymerization process, the mechanical modification of the second reactor, was improved and the causes of leakage were analyzed. The solution to the problem of machine seal leakage was put forward. The mechanical seal before and after the improvement was given, and the technical specifications for the overhaul and installation of the second reactor were given. After the transformation of the mechanical seal operation cycle reached 1 year, greatly reducing production costs, extending the life cycle.
