一种用于分离C9-C11金属轧制液的精馏塔塔板结构

Abstract

一种用于分离C9‑C11金属轧制液的精馏塔塔板结构，涉及分离金属轧制液技术领域，在塔盘（1）的中心部位设有多个阀孔（102），在阀孔（102）和降液孔（101）之间的塔盘（1）顶部设有溢流堰（2），螺母（503）和外螺纹螺接将插管（502）固定在阀孔（102）内，降液筒（3）的筒腔和降液孔（101）贯通，在降液筒（3）的筒壁位于阀孔（102）的一侧间隔设有多个出液孔（301）；本实用新型上升的气相通过插管中间的圆孔上升经过阀片与插管之间的间隙进入塔盘的顶部，和塔盘顶部的液相气液进行接触，上升的气流推动阀片上升、阀片的自重带动阀片下降，阀片往复的进行上下运动，使得气液接触更充分。
