三管反应器的头部调整与运转稳定性

Adjustment of Head Design and Performance Stability of a Multitube Sulfonator

对引进设备的三管磺化器在冷膜调试时取得了满意的液体均等分配结果，但在负载试车时表现异常。通过对试验现象的分析，认识到分配器设计欠妥。列管式磺化器是由一组彼此平行、内壁光滑的具有一定直径和长度的不锈钢管子组成。反应器头部有一有机物分配腔。每根管子的头部装有加工精密的分布头以保证有机反应物均等分配于每根管。气相反应物三氧化硫的均等分配是借助各单管相同的流动阻力降来实现的。解决该问题的过程中发现，分配器缝隙液体流动阻力必须大于某一极限值才能保证实际运转的稳定性。该结论通过α－烯烃（ＡＯ）的磺化得到验证。

Multitube sulfonator consists of a group of stainless steel tubes arranged in parallel.It has an organic raw material chamber at the head of the reactor and each tube has a carefully designed distributor equipped at the top,which ensure the equivalent distribution of organic material in each tube.The concerned sulfonator gave satisfactory result in cold film calibration,but worked inormally in loaded test running.Through resolving this problem,it is found that a minimum organic feeding pressure drop at the distributor is required for the stable running of multitube sulfonator.
