The device comprises a distillation structure used for heating and condensing an object to remove impurities of the object, and the distillation structure is connected with a settling structure used for settling the impurities of the object; the distillation structure comprises a feeding body for controlling an object to enter and exit, the bottom of the feeding body is connected with a storage body for temporarily storing the object, the storage body is internally connected with a connecting pipe, the connecting pipe is connected with a distillation body for distillation, and the distillation body is connected with a condensation body for condensing a gas object and a sedimentation pipe; the settling structure comprises a pretreatment body for pretreating the solid-liquid mixture, and the pretreatment body is connected with a sedimentation treatment body for carrying out sedimentation treatment on the solid-liquid mixture. The invention mainly provides the distillation device for removing impurities in a sedimentation mode.

Description

technical field [0001] The invention relates to the technical field of purification and distillation equipment, in particular to a distillation device based on a sedimentation and impurity removal mechanism. 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. Compared with other separation methods, such as extraction, filtration and crystallization, the combination of unit operations has the advantage 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.

Problems solved by technology

[0003] Existing chemical companies and pharmaceutical companies need to separate substances with different boiling points through distillation in the production process. Distillation devices are needed in the process of distillation separation. The structure design of traditional distillation devices is not reasonable enough. During the distillation process, when When the reflux material flows into the distillation column from the condenser, part of the material will flow into the inner wall of the distillation column along the pipe wall, resulting in less heat exchange of the material reflux, rapid temperature rise of the column item, less heat exchange, high energy consumption, and slow distillation efficiency.
