TECHNICAL FIELD

[0001] The utility model relates to solvent separation technical field, concretely is a kind of industrial grade solvent separation treatment device. BACKGROUND

[0002] Industrial grade solvent is widely used in industrial production, and common types include organic solvents and inorganic solvents. Among organic solvents, aromatic hydrocarbon solvents such as toluene and xylene are widely used in the paint and ink industry to dissolve resins and pigments. Ketone solvents such as acetone and butanone are commonly used in plastic and rubber processing due to their strong solubility and moderate volatility. Water, as the most common inorganic solvent, is an ideal medium for many chemical reactions.

[0003] However, the distillation unit of the traditional solvent separation treatment device needs precise temperature control when separating the partially vaporized mixed solvent by heating with a reboiler. This requires the reboiler to continuously consume a large amount of heat energy to maintain the gas-liquid balance and mass and heat transfer processes in the tower. For solvents with similar boiling points, higher temperatures and longer times may be required for effective separation, further increasing energy consumption. In the current energy cost environment, this undoubtedly increases the cost of industrial production. Therefore, we propose an industrial grade solvent separation treatment device. SUMMARY
