皆様親愛なる海の友: 德士古加hydror气化下降管刮渣是否会引起锁斗超温?为什么?
Reply #22017-06-03
上升,因为下降管内壁挂渣嚴重会使通道变窄,粗煤气通过后气速变快,进入激冷室水域更深,锁斗变泵一回,温度自然就涨了

看起来锁斗温度升高与下降管挂渣之间没有证据能证明有直接联系吧?二楼的观点还不足以说服我,请高手求解

个人分析如下: 一. 根据热交换平衡的原理,在没有挂渣的情况下,合成气携带的热量、渣水循环量以及渣锁斗表面向空气中散发的热量是保持平衡的;这个时候的渣锁斗表面温度和渣水温度应该都是稳定的; 二. 假设下降管挂渣,在挂渣的初期,下来的渣带来的温度在流动的过程中会扩散引起渣锁斗壁温的上升;但是因为热量不大都通过外壁扩散出去了,渣水温度应该不变; 三. 进一步挂渣,大量的渣会在下降管内壁凝固;这个凝固的渣不是热的良导体;当凝固到一定厚度时,大量的热就往渣水侧扩散了;这个时候,循环渣水的温度应该会上升;有可能下降管外壁的温度会下降

降管挂渣与急冷室底部架桥类似,锁斗在收渣阶段上部温度上涨较快,异于正常曲线?
