Material liquid concentration device and material liquid evaporator thereof

Abstract

The invention provides a material liquid concentration device and a material liquid evaporator thereof. The material liquid concentration device comprises a heater for heating a material liquid, an evaporation chamber, and a vacuum pump for enabling a negative pressure environment to be generated in the evaporation chamber, wherein a first pipeline by which the material liquid is conveyed into the evaporation chamber from the heater and a second pipeline by which the material liquid returns to the heater from the evaporation chamber are arranged between the heater and the evaporation chamber; the first pipeline is connected with one end of the evaporation chamber, so that the material liquid can form eddies at the inner side of the side wall of the evaporator by a spiral section. The spiral section is arranged on the first pipeline, so that the material liquid passing through the spiral section and entering the evaporation chamber can form the eddies moving in a downwards spiral manner at the side wall of the evaporation chamber, the evaporation specific surface area of the material liquid entering the evaporation chamber is enlarged, and the evaporation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medicinal liquid concentration, in particular to a feed liquid concentration device and a feed liquid evaporator thereof. Background technique [0002] In the technical fields of pharmacy and chemical industry, in order to realize the purification and concentration of effective substances, it is generally necessary to use a material-liquid concentration device for concentration and purification. The liquid medicine concentration device generally uses a heater to heat the low-concentration feed liquid, and uses the film-forming technology to generate a foam mixture in the heater and transport the foam mixture to the evaporation chamber through a pipeline, so that the liquid medicine can be rapidly evaporated under negative pressure conditions. evaporation. [0003] In the existing production equipment, the heater and the evaporation chamber are connected through a short straight-through pipeline, and the ...

AI Technical Summary

Problems solved by technology

[0003] In the existing production equipment, the heater and the evaporation chamber are connected through a short straight-through pipeline, and the foam mixture generated by the film directly enters the evaporator and quickly falls to the bottom of the evaporator and returns to the heat exchanger. Effectively increase the evaporation area, reduce the evaporation efficiency and increase energy consumption
