Description
技术领域 technical field
本实用新型涉及乙基酯生产领域，具体涉及一种基酯生产用碳乙醇回收装置。 The utility model relates to the field of ethyl ester production, in particular to a carbon ethanol recovery device for ethyl ester production.
背景技术 Background technique
乙基酯生产中回收乙醇及碳酯的回收装置通常包括蒸馏釜、蒸馏塔和冷凝器，液体陷阱蒸馏釜蒸馏后送入蒸馏塔分离吸收，最后经冷凝器冷凝回收。现有技术中的蒸馏釜都为立式蒸馏釜，在釜体的外壁上安装夹套或者釜体内壁设置夹层，在夹套或夹层内通入热水或热蒸汽经行加热，也有在釜体内部上安装电加热的技术方案，这些方案的缺陷在于，当釜体内的液位降低时，液位以上的加热部分所产生的热量利用率就较低，浪费能源和成本；而填料塔内的蒸汽上升的过程中通常会有部门蒸汽在塔节的内壁上凝结并顺着塔节内壁向下流，这样带来的问题是，顺壁下流的液体不能够与填料接触吸收，且液体易从塔节连接处渗漏，带来污染和腐蚀；回收装置通常只使用一个冷凝器冷凝，不能冷凝完全，冷凝器中未冷凝的气体排出后易浪费原料且污染环境。 The recovery device for recovering ethanol and carbon esters in the production of ethyl ester usually includes a still, a distillation tower and a condenser. The liquid trap is distilled in the still and sent to the distillation tower for separation and absorption, and finally condensed and recovered by the condenser. The stills in the prior art are all vertical stills. A jacket is installed on the outer wall of the still body or an interlayer is installed on the inner wall of the still body, and hot water or hot steam is passed into the jacket or interlayer for heating. The technical scheme of installing electric heating on the inside of the kettle body, the defect of these schemes is that when the liquid level in the kettle body is lowered, the utilization rate of heat generated by the heating part above the liquid level is low, which wastes energy and cost; During the rising process of steam, part of the steam usually condenses on the inner wall of the tower section and flows downward along the inner wall of the tower section. The problem brought about by this is that the liquid flowing down the wall cannot be contacted and absorbed by the packing, and the liquid is easy to flow from Leakage at the connection of the tower joints brings pollution and corrosion; the recovery unit usually only uses one condenser to condense, which cannot be completely condensed, and the uncondensed gas in the condenser is easy to waste raw materials and pollute the environment after being discharged.
