说 明 书 反应器底部整流器 技术领域
本发明涉及石化冶炼反应器中的整流器， 尤其是涉及一种用于反应器中原 料油整流器。
背景技术
众所周知， 石化反应器底部是一个收缩过程， 由于短路和湍流影响， 在反应 器底部的液油径向阻力有较大差异， 正是这种差异导致底部主剂上液油分布不 均匀， 形成液流阻力中心大外部小的分布状态， 低了主剂的使用效杲， 从而 会影响反应器的反应效率。
发明内容
针对上述现有技术中存在的问题， 本发明提供了一种适用于反应器底部使用 的、 可使液油在反应器底部形成均匀致密流动的反应器底部整流器。
本发明要解决的技术问题所采取的技术方案是： 所述反应器底部整流器包括 用鸟巢蜂窝陶瓷制成的中心层、 至少一个夹层和外层， 所述中心层、 夹层和外 层孔隙率依次增大， 所述中心层、 夹层和外层分别设置在同心布置的中心层圓 锥形体内、 夹层圓锥形体内和外层圆锥形体内， 所迷反应器底部整流器内形成 有不同孔隙率的网状蜂窝孔。
本发明由于釆用具有最小密度在 200 目以上的高密度蜂窝孔的鸟巢陶瓷制 成， 由于鸟巢具有巨大的孔隙率和繁密的网格， 且从中心到边缘鸟巢蜂窝孔孔 隙率依次增大的结构， 当液态原料进入反应器底部时， 能使液油在主剂层上形 成的水点剖析次数大大提高， 流动分布就更均勾， 使液油在主剂层能形成致密 的更均勾的分布， 可以最大限度消除湍流的影响， 从而可提高液油的反应效果， 说 明
提高反应器的反应效率。
