Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] It should be noted that, in the embodiment of the present invention, the heating part 20 has a first preset temperature value A1, and the separating part 30 has a second preset temperature value A2, wherein A1>A2. That is to say, during the purification process, it is always ensured that the temperature of the heating part 20 is higher than the temperature of the separation part 30 .

[0025] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a vacuum purification device. The vacuum purification device includes a delivery pipeline 10 , a heating part 20 , a separation part 30 , a condensation part 40 and a vacuuming device 50 . Wherein, the con...

Abstract

The invention provides a vacuum purification device and a purification system. The vacuum purification device comprises a conveying pipeline which is used for conveying raw materials; a heating part which is communicated with the conveying pipeline, is used for heating the raw materials to form gas with liquid drops and liquid containing impurities, and is provided with an inlet and an outlet; a separation part which is communicated with the inlet of the heating part, and is used for treating the gas with liquid drops; a condensation part which is communicated with the separation part and is located at the end, away from the heating part, of the separation part; and a vacuumizing device which is communicated with the condensation part. Under the action of the vacuumizing device, the cavities of the conveying pipeline, the heating part, the separation part and the condensation part are all in a vacuum state. According to the technical scheme, the problem that raw materials are easily deteriorated due to long-time raw material heating by a vacuum purification device in the prior art is solved.

Description

technical field [0001] The invention relates to the field of medicine and chemical industry, in particular to a vacuum purification device and a purification system. Background technique [0002] Raw materials and products in the pharmaceutical and chemical industry usually have the characteristics of large molecular weight, complex structure, and high boiling point, while their crude products are often colored and contain various impurities with close boiling points. The method of rectification and purification has the advantages of simple operation, large processing capacity, and low equipment cost. However, most fine chemical products are heat-sensitive, and heating at high temperature for a long time will not only lead to product deterioration, but also pose potential safety hazards. [0003] In the prior art, the distillation device can remove the color of the raw material and has a certain purification effect. However, the distillation device will heat the material fo...
