Abstract

The invention discloses a diethyltoluenediamine hydrolysis solvent distillation recovery device, which relates to the technical field of solvent distillation recovery, including a reaction kettle, a partition plate is fixedly installed in the reaction kettle, and a reaction kettle above the partition plate The space is set as the first processing bin, the space of the reaction kettle below the partition plate is set as the second processing bin, and the first processing bin and the second processing bin are connected and arranged through a drainage tube, and a control device is fixedly installed in the drainage tube. A liquid valve, a processing mechanism is provided in the first processing chamber, and an automatic sealing mechanism is provided in the inner wall of the upper end of the reaction kettle. Through the setting of the processing mechanism, the mass transfer separation mechanism, the automatic sealing mechanism and the heat circulation mechanism, the present invention not only automatically cuts off the material, but also performs electrolytic preliminary treatment and distillation recovery treatment on the solution, making full use of the steam energy while passing mass transfer The separation method improves the efficiency of distillation recovery.

Description

technical field [0001] The invention relates to the technical field of solvent distillation recovery, in particular to a diethyltoluenediamine hydrolysis solvent distillation recovery device. Background technique [0002] In the production process of diethyltoluenediamine, arylamine aluminum / zinc is used as an alkylation catalyst, and arylamine aluminum / zinc is a metal compound. The compound is a solid substance, and the reaction liquid is a liquid phase, which contains diethyltoluene diamine. Diethyltoluenediamine, ethyltoluenediamine and the arylamine aluminum / zinc formed with aluminum are metal compounds, and this part of the metal compound can be dissolved in diethyltoluenediamine to form a mixed phase state. [0003] Although the existing diethyltoluenediamine hydrolysis solvent distillation recovery device can complete the distillation recovery of diethyltoluenediamine hydrolysis solvent, the efficiency of recovery and the utilization efficiency of heat are not high, s...
