Abstract

The invention discloses a plate-type feed liquid evaporator. The evaporator includes a first-level heater and a first-level evaporating chamber which are communicated with each other and used for heating, evaporating and separating feed liquid; the evaporator further comprises a second-level heater and a second-level evaporating chamber which are communicated with each other, wherein a feed liquid pipeline and a steam passage which are communicated with each other are arranged on the communicated part between the second-level heater and the first-level evaporating chamber; steam produced by the first-level evaporating chamber serves as a heating source, the second-level evaporating chamber is connected with a vacuum pump for decreasing the air pressure inside the second-level evaporating chamber. Through arrangement of the second-level heater and the evaporating chambers, the feed liquid can be separated more thoroughly; since the second-level heater is communicated with the first-level evaporating chamber and the steam produced by the first-level evaporating chamber serves as the heat source for the second-level heater, the energy is saved; by connecting the second-level evaporating chamber, used for secondary evaporation and separation of the feed liquid, with the vacuum pump, an indoor low-pressure working environment is provided for the second-level evaporating chamber, so that the indoor boiling point of the second-level evaporating chamber is decreased, and it is ensured that the evaporation and separation of the feed liquid can still be conducted efficiently through the second-level heater and the evaporating chambers.

Description

technical field [0001] The invention relates to the technical field of raw material liquid concentration, and more specifically relates to a plate-type material liquid evaporation device. Background technique [0002] At present, 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 feed-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 rising film technology to generate the droplet companions in the heater and transport the droplet companions to the evaporation chamber through the pipeline, so that the medicine The liquid evaporates rapidly. [0003] In the existing production equipment, most of the shell-and-tube heaters or plate heaters are connected to the evaporation chamber through a short straight-through pipeline, a...
