Description

一种用于芳烃溶剂的板式精馏塔 技术领域
本实用新型涉及一种塔式汽液接触装置，更具体地说，它涉及一种用于芳烃溶剂的板式精馏塔。
背景技术

现有公开号为CN106902533A的中国专利提供了一种苯甲醛生产用精馏塔，其包括筒体状结构的精馏塔主体；精馏塔主体的中部设置有料液进口，以供芳烃溶剂等下降液进入；精馏塔主体的内部设置有多层分布器，以供芳烃溶剂等下降液不断向下流动；精馏塔主体下端的最低处设置有釜液出口，以供芳烃溶剂等下降液流出。精馏塔主体的底部设置有气相进口，以供芳烃溶剂等蒸汽进入；分布器上贯穿设置有通气孔，以供芳烃溶剂等蒸汽不断向上移动；精馏塔主体的上端设置有气相出口，以供芳烃溶剂等蒸汽排出。在使用的过程中，分布器处的蒸汽与下降液相接触；下降液中易挥发组分不断向蒸汽中转移，蒸汽中的难挥发组分不断向下降液中转移，从而实现芳烃溶剂等下降液组分分离的目的。
但是，由于芳烃溶剂等蒸汽向上移动的速度较快，所以芳烃溶剂 等下降液与蒸汽的接触时间较短，芳烃溶剂等下降液组分分离的不充分，故有待改善。

参照图1和图2，塔板2贯穿设置有贯穿孔22，贯穿孔22内侧壁通过轴承转动设置有旋转轴3。旋转轴3位于每一塔板2的上方均设置有旋转片4，以用于使蒸汽不断在相邻塔板2之间的空间内转动。旋转片4位于其转动方向的一侧向下延伸设置有抵液片41，以与液体相抵；从而使液体飞溅，增大与蒸汽的接触。抵液片41与塔板2 之间设置有流水间隙23，以保证一定量的下降液不断的在塔板2上流动。
参照图2，旋转片4背离其转动方向的一侧向上倾斜设置，以使旋转片4上的下降液向上喷洒的效果更好；旋转片4位于上方的一侧设置有若干个分离齿42，以用于使旋转片4上的下降液充分散开。
参照图1和图3，塔体1的上端设置有安装孔16，旋转轴3的上端向塔体1的上方延伸，并与安装孔16内侧壁转动连接。旋转轴3连接有电机，电机作为驱动件5，以用于驱动旋转轴3进行转动。电机位于塔体1的外部，且电机位于安装孔16的一侧，以防止蒸汽直接移动至电机的外侧壁；电机的转动轴与旋转轴3之间连接有传动带51，传动带51为橡胶带或同步带。
参照图3，安装孔16内侧壁嵌设有轴承161，轴承161的内侧壁与旋转轴3外侧壁相贴合，以提高旋转轴3的稳定性。安装孔16内侧壁通过焊接的方式固定设置有支撑环162，支撑环162位于轴承161的下方，以防止轴承161掉落至塔体1内。

蒸汽经进气管13进入塔体1内，并通过塔板2上的通气孔21，不断的塔体1的上方流动。蒸汽与下降液接触的过程中，实现组分分离的目的。
在此过程中，电机带动旋转轴3转动；同时，旋转片4不断的转动，使蒸汽在相邻塔板2之间的空间内不断的周向转动，以使蒸汽充分与下降液接触；抵液片41与塔板2上流动的下降液接触后，由于旋转片4处于转动的状态，从而使下降液延伸旋转片4的宽度方向向上流动，并被分离齿42分散开，使下降液与蒸汽充分接触；实现有效提高下降液与蒸汽充分接触的目的。
