Description

一种分馏塔塔顶温度调节控制装置 技术领域
本发明涉及化工设备技术领域，具体为一种分馏塔塔顶温度调节控制装置。
背景技术
化工设备是化工机械的一部分，化工机械包括两部分，其一是化工机器，主要是指诸如流体输送的风机、压缩机、各种泵等设备，其主要部件是运动的机械，一般称为化工机器。其二是化工设备主要是指部件是静止的机械，诸如塔器等分离设备，容器、反应器设备等，包括化工设备在内的所有化工机械都是化学工厂中实现化工生产所采用的工具。化工产品生产过程的正常运转，产品质量和产量的控制和保证，离不开各种化工设备的适应和正常运转。化工设备的选配必需通过对整个化工生产过程的祥细计算、设计、加工、制造和选配，要适应化工生产所需要，化工设备种类繁多，分类方法具有多种方式方法，例如按结构材质分，可分为碳钢设备、不锈钢设备、非金属设备。按承受压力可分为高压设备、中压设备和真空设备、常压设备等，化工容器类：有槽、罐、釜等；分离塔器类：有填料塔、浮阀塔、泡罩塔、转盘塔等；反应器：有管式反应器、流态化反应器、搅拌釜反应器等；换热器：有列管式、板式换热器、蛇管换热器等；加热炉：有电加热炉、管式裂解炉、废热锅炉等；结晶设备：溶液结晶器、熔融结晶器等；其他各种专用化工设备等。
分馏塔在有限的空间内，尽可能的增大液相混合物的热交换面积，一般用于分馏的混合物为有机共沸物，共沸物从反应釜内首先受热上升至分馏段，沸点低的继续上升，因为塔顶在受到低沸点物的传热后温度和低沸点物一致，所以低沸点物被分馏出来，而较高沸点物因为没有达到相应的沸点，故会受冷却后回流至反应釜内或分馏柱下半部分，待低沸点物被完全馏出后，较高 沸点物相继被分馏，然后是高沸点物的馏出，最后反应釜底部是残渣，目前用于石油分离装置采用分馏塔进行分离，就催化裂化装置的生产而言，在保证安全、产品质量和环保的前提下，适当调节分馏塔的塔顶温度，进而控制分馏塔的切割点，从而控制不同馏分的收率，现有技术中，通过冷却水的方式控制分馏塔的塔顶温度，但由于水的热容较大，温度不易控制，影响分馏效果，不能满足生产要求。
