Distilling equipment for organic solvent recovery

Abstract

The invention belongs to the field of screening equipment and specifically relates to distilling equipment for organic solvent recovery. The distilling equipment comprises a hollow metal ball for accommodating a solvent to be distilled, wherein a vertical tube is communicated to the top of the metal ball, two groups of hollow spherical cavities communicated with the vertical tube are cut in a lateral wall of the vertical tube, through tubes are arranged on inner walls of the spherical cavities, electrodes connected with a power supply are loaded to the tops and the bottoms of the through tubes, flat thin magnets are hinged to the upper ends and the lower ends of connection openings between the spherical cavities and the vertical tube, the flat thin magnets are used for sealing the connection openings and have different magnetic poles, wires communicated with the electrodes are wound to the ends of the flat thin magnets, the metal ball is sleeved by a semicircular heating ball, an ejector pin capable of clamping the metal ball is arranged on the heating ball, a plurality of groups of annular heating wires are arranged on an inner wall of the heating ball, a lead block is arranged atthe bottom of the metal ball, and a base for supporting is fixedly connected to the bottom of the heating ball. According to the distilling equipment disclosed by the invention, a plurality of loopsare utilized to heat the solvent of the distilling equipment; furthermore, a filtering measure is arranged in midway, so that the distilling efficiency and distilling quality are improved.

Description

technical field [0001] The invention belongs to the field of solvent treatment, and in particular relates to a distillation device for recovering organic solvents. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. [0003] When the current distillation equipment is working, a single heat source is used to heat the solvent, and the solvent will be heated unevenly, which makes the temperature of the solvent in the distillation ...

AI Technical Summary

Problems solved by technology

[0003] When the current distillation equipment is working, a single heat source is used to heat the solvent, and the solvent will be heated unevenly, which makes the temperature of the solvent in the distillation equipment inconsistent, and it is easy to cause the distillation equipment to burst due to uneven heating. Potential safety hazard; and The uneven heating of the solvent will also make the distillation efficiency low; and in the existing distillation equipment, some solvents in the solvent that are not needed or are not the target components are also distilled together, which reduces the purity of the target solvent and increases the post processing difficulty
