Solvent distillation recovery device

Abstract

The invention belongs to the field of solvent recovery and in particular discloses a solvent distillation recovery device. A vertical tube penetrates through a distillation tube; an upright post for supporting is arranged at the bottom of the vertical tube; an inlet door is installed at the left side of the distillation tube; an outlet door is installed at the right side of the distillation tube;two concentric sliding chutes positioned outside the distillation tube are symmetrically arranged on the side walls of the vertical tube; balls are sequentially connected into the sliding chutes in asliding manner; spiral heating wires are connected onto the balls; v-shaped covers are arranged outside the inlet door and the outlet door; edges at larger ends of the v-shaped covers are connected with the heating wires; a rotating motor is arranged at smaller ends of the v-shaped covers; supporting rods are arranged at the bottom of the motor; a pressure block is connected into the vertical tubein a sliding manner; a curved tube through which a solvent circulates is arranged inside the pressure block; and an outlet tube matched with the curved tube is arranged on the side wall of the vertical tube. With the adoption of an annular heating manner, the problem of non-uniform heating of distillation equipment is solved; and with the adoption of a unique structural design, rapid distillationis realized, and heat loss is reduced.

Description

technical field [0001] The invention belongs to the field of solvent recovery, and specifically discloses a solvent distillation recovery device. Background technique [0002] Distillation is a thermodynamic separation process, which utilizes the different boiling points of each component in a mixed liquid or liquid-solid system to evaporate the low-boiling component and then condense to separate the entire component. Union of unit operations. Compared with other separation methods, such as extraction, filtration crystallization, etc., its advantage is that it does not need to use other solvents other than system components, thus ensuring that no new impurities are 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, so that the temperature of the solvent in the distillation equipment is inconsistent, and it is easy to cause the distillation equipment to explode du...

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 prone to safety hazards of the distillation equipment bursting due to uneven heating; Moreover, the uneven heating of the solvent will also lead to low distillation efficiency; and in the existing distillation equipment, the solvent will begin to evaporate gradually when heated, and the distillation temperature of most of the solvents in the solvent is under the action of this evaporation effect. will be taken away, so that the temperature of the entire solvent rises very slowly, so that the distillation takes a long time, which is not conducive to the use of heat and wastes a lot of energy
