摘要:

水煤浆气化、粉煤气化的激冷流程均采用锁斗排渣工艺,都面临着一个共同的问题,锁斗排渣时振动非常大,各公司因为工艺配管的不同差别振动差别也比较大,近年设计院与运行厂家在测试各种方案来解决锁斗排渣振动的问题,例如:锁斗冲洗管线增加弹性支撑、增加波纹软管、改变冲洗水管配管等方式,虽然都有一定效果,但还没有根本的解决振动问题。该振动给高温高压系统管道、设备的安全运行带来极大的风险。本文通过从锁斗振动产生的根本原因入手,彻底解决锁斗排渣振动问题。

Coal water slurry gasification and chilling of pulverized coal gasification process adopt the lock hopper discharge process and are both facing a common problem that the vibration of lock hopper discharge is very obvious. The vibration changes as the process piping of each is different. In recent years, the design institute and coal gasification company have tested different kinds of solutions to solve the vibration of lock hopper, such as adding elastic support or corrugated hose, changing the way of flushing water pipe etc. All these solutions have some certain effects, but the problem still can’t be essentially solved. The vibration to high temperature and high pressure pipeline system, the equipment safe operation brings great risk. This article thoroughly solves this problem by analyzing the root cause of vibration.
