The upper end and the lower extreme of tubulation 3 are provided with shrouding I4 and shrouding II 5 respectively, and the top of shrouding I4 is provided with the below that stops chamber I7, shrouding II 5 and is provided with and stops chamber II 8. The upper end and the lower end of the tube array 3 are respectively opened in a staying cavity I7 and a staying cavity II 8.

A circulating pipe I9 is arranged between the staying cavity I7 and the evaporation chamber 2, and two ends of the circulating pipe I9 are respectively communicated with the staying cavity I7 and the evaporation chamber 2. A circulating pipe II 10 is arranged between the staying cavity II 8 and the evaporation chamber 2, and two ends of the circulating pipe II 10 are respectively communicated with the staying cavity II 8 and the evaporation chamber 2.

Sealed heating cavities 6 are formed between the sealing plates I4 and II 5 and between the tubes 3. A steam inlet pipe 11 is connected into the heating cavity 6, and high-temperature steam is introduced into the heating cavity 6 through the steam inlet pipe 11. The liquid medicine to be heated is loaded in the tube array 3, flows into the lower end of the tube array 3 from the staying cavity II 8, and flows out from the upper end of the tube array 3 to enter the staying cavity I7. The liquid medicine is heated by the high-temperature steam in the heating cavity 6 in the process of flowing through the tube array 3 and boils in the staying cavity I7, and is sprayed out to the evaporation chamber 2 through the circulating tube I9, and the liquid medicine is evaporated and concentrated in the evaporation chamber 2. The cooled liquid medicine in the evaporation chamber 2 enters the retention chamber II 8 through the circulating pipe II 10 and further enters the tube nest 3 to be heated, and the process is repeated.

As shown in fig. 1, the bottom of the heating chamber 1 is provided with a discharge pipe 22, and the discharge pipe 22 is connected to the heating chamber 6 for discharging steam and condensed water. A condensate trap bypass pneumatic valve 23 is provided on the discharge pipe 22. As shown in fig. 2, the condensate trap bypass pneumatic valve 23 is connected to the output of the controller 15 and controlled.

The heating chamber 1 and the evaporation chamber 2 are in a vacuum state to boil the chemical liquid at a low boiling point.

In order to monitor and adjust the pressure of the heating steam in real time, a steam pressure detector 13 and a steam pneumatic adjusting valve 12 are arranged on the steam inlet pipe 11. Referring to fig. 2, the steam pressure detector 13 is connected to an input end of a controller 15, an output end of the controller 15 is connected to the steam pneumatic regulating valve 12, and when the pressure value exceeds or is lower than a set value, the steam pneumatic regulating valve 12 is automatically regulated.

As shown in fig. 1, a vacuum pneumatic control valve 14 is further provided in the evaporation chamber 2, and the degree of vacuum is controlled by the vacuum pneumatic control valve 14. An online pressure detector 18 is also arranged in the evaporation chamber 2 and used for monitoring the pressure in the evaporation chamber 2.
