Description

一种油水连续分离系统
技术领域
本实用新型属于有机化工装置领域,具体涉及一种不互溶液体的分离系统。
背景技术
3,5-二甲基苯酚是重要的化工中间体,主要用于制备抗氧化剂、抗生素、树脂粘合剂和维生素E等的生产。现有的3,5-二甲基苯酚制备方法包括间二甲苯磺化碱熔法和异佛尔酮的芳构化反应。间二甲苯磺化碱熔法合成方法工艺过程复杂,腐蚀设备,此外,由于磺化过程中,生成的产物中不仅是3,5-二甲基苯磺酸,还会有2,4一二甲基苯磺酸,这样最终的产物将会含有2。4一二甲基苯酚。从3,5一二甲基苯酚中分离出2,4一二甲基苯酚是十分困难的。异佛尔酮催化芳构化一步合成3,5一二甲基苯酚,是更环保经济的方法。
异佛尔酮在高温下进行反应,异佛尔酮的酚酮重排,生成3,5一二甲基苯酚和甲烷外还涉及异佛尔酮的分解,生成了一定量的低沸点的芳香族副产物。在3,5-二甲基苯酚精馏提纯工艺中,一般需要采用多级深冷的办法回收这些副产物。但是采用多级深冷,能耗太大,而且仍有部分有机物进入真空水池,处理不善则造成环境污染。
实用新型内容
针对本领域的不足之处,本实用新型的目的是提出一种油水连续分离系统,对异佛尔酮的芳构化反应的产物进行分离回收。本实用新型主要保护该装置在异佛尔酮芳构化生成的3,5-二甲基苯酚精馏精制过程中对低沸点有机物的回收利用。
实现本实用新型上述目的技术方案为:
一种油水连续分离系统,其包括密闭真空水池、油水分离罐、存水罐、循环泵;
所述密闭真空水池设有溢流口,所述油水分离罐通过管道与所述密闭真空水池的溢流口连接;所述油水分离罐顶部设置有排水阀,所述排水阀通过管道连接所述存水罐;所述存水罐上部设置有排油阀,排油阀连接有油水界面仪,所述排油阀通过管道连接有油桶;
所述存水罐上设置有液位显示控制装置,所述存水罐还连接有循环水泵,所述液位显示控制装置电连接所述循环水泵。
存水罐上安装液位显示控制装置,实现存水罐液位联锁控制循环泵。当液位达到上限时,启动循环水泵,进行排水操作;当液位达到下限时,关闭循环水泵,开始下一周期运行。
其中,所述循环水泵还与所述密闭真空水池连接。存水罐里的水通过循环水泵打入真空水池回用。
本实用新型的有益效果在于:
本实用新型提出的系统实现了更完全的油水分离,使得分离出的油中含水量低,可以直接销售;而水则通过循环泵打回密闭的真空水池套用。减小精馏过程中,低沸点有机物对环境得污染;减轻了工人的劳动强度,只要定时开启排油阀,将油进行装桶。整个过程操作简单,高效。
