[0021] Figure 1 The shown liquid medicine concentration treatment device includes a heat pump unit 1, a one-effect heating chamber 2, a one-effect evaporation chamber 3, a two-effect heating chamber 4, a two-effect evaporation chamber 5, a condensing device 6, a liquid receiving tank 7 and an ultrasonic descaling device 8. The input port of the one-effect heating chamber 2 is connected with the output end of the heat pump unit 1 through a connecting pipeline. The one-effect heating chamber and the two-effect heating chamber are of the same height. The output port of the one-effect heating chamber 2 is connected with the input port of the one-effect evaporation chamber 3 through a connecting pipeline. The output port of the one-effect evaporation chamber 3 is connected with the input port of the two-effect heating chamber 4 through a connecting pipeline. The output port of the two-effect heating chamber 4 is connected with the input port of the two-effect evaporation chamber 5 through a connecting pipeline. The output port of the two-effect evaporation chamber 5 is connected with the input port of the condensing device 6. The one-effect evaporation chamber 3 and the two-effect evaporation chamber 5 are both provided with an observation window 10. The inner side of the observation window 10 is provided with a water vapor-proof coating. The condensing device 6 is connected with the input end of the heat pump unit 1. The bottom of the condensing device 6 is provided with the liquid receiving tank 7. Each of the connecting pipelines is provided with a clamp 9. Each of the clamps 9 is provided with the ultrasonic descaling device 8. The ultrasonic descaling device 8 includes an ultrasonic generator, a transducer, a detection module and a control module. The ultrasonic generator is fixedly connected with the clamp 9. The transducer is fixedly connected with the connecting pipeline. The ultrasonic generator and the transducer are electrically connected through wires. The detection module is used for detecting the output voltage, the output current and the working frequency of the ultrasonic generator and generating real-time working logs. The control module is used for controlling the running state of the ultrasonic generator. The ultrasonic generator, the detection module and the control module are all electrically connected through wires. Through the one-effect heating chamber 2, the two-effect heating chamber 4 and the heat pump unit 1, the two-effect heating chamber 4 can utilize the waste heat in the one-effect heating chamber 2. The heat pump unit 1 can re-deliver the heat released by the condensing device 6 back to the evaporation chamber of the one-effect heating chamber 2, so as to make the heat recycling further improved, reduce the consumption of high-temperature steam and greatly reduce the annual energy cost. The ultrasonic generator can output descaling ultrasonic waves. The ultrasonic waves will not affect the concentration of the liquid medicine during the operation of the concentrator. Therefore, the ultrasonic generator does not need to be maintained when the machine stops working, but can continuously descale. The ultrasonic generator has the effects of descaling and scale prevention. The descaling of the pipeline has great benefits. The most important one is that it can keep the vacuum degree of the concentrator at a high initial level. In this way, the boiling point of the liquid medicine is reduced, the consumption of high-temperature steam is less, and the energy is further saved.
[0022] As Figure 1As shown, the heat pump unit 1 comprises an evaporator 11, a condenser 12 and a compressor 13, the evaporator 11 is arranged at the inner top end of the condensing device 6, the output port of the evaporator 11 is connected with one end of a first expansion valve through a circulating pipeline, the other end of the first expansion valve is connected with the input port of the compressor 13 through a circulating pipeline, the output port of the compressor 13 is communicated with the input port of the condenser 12 through a circulating pipeline, the condenser 12 is provided with a heat collecting device, the heat collecting device is used for providing high-temperature steam for the first heating chamber 2, the output port at the bottom of the condenser 12 is provided with a liquid storage tank 14, the output port of the liquid storage tank 14 is communicated with one end of a second expansion valve through a circulating pipeline, the other end of the second expansion valve is communicated with the input port of the evaporator 11, through the heat pump unit 1, the evaporator 11 can deliver the heat emitted by the condensing device 6 in the concentrator to the condenser 12 through a circulating pipeline, and the condenser 12 can release heat in the first heating chamber 2, so that the heat utilization rate is further increased outside the first heating chamber 2 and the second heating chamber 4, and the energy consumption is greatly reduced.
[0023] Specific implementation process: the high-temperature steam in the first heating chamber 2 enters the first evaporation chamber 3, the drug liquid is affected by the high-temperature steam in the evaporation chamber, so that the drug liquid starts to boil in the vacuum environment, and the excess liquid is converted into gas and enters the second heating chamber 4 from the pipeline along with the high-temperature steam. Although the second heating chamber 4 is also connected with the high-temperature steam supply pipeline, the required high-temperature steam consumption of the second heating chamber 4 is lower with the help of the first heating chamber 2. The high-temperature steam of the two chambers is combined into one, enters the second evaporation chamber 5, and heats the drug liquid to the predetermined concentration. Then the drug liquid enters the condensing device 6, the waste heat is absorbed by the evaporator 11 in the heat pump unit 1 and delivered to the condenser 12 through a circulating pipeline, and the heat is provided for the first heating chamber 2 again, so that the energy is further circulated. The ultrasonic descaling device 8 always keeps running and does not need to work after the concentrator stops working. It can play a dual effect of descaling and anti-scaling. It always releases ultrasonic waves through the transducer to descale the inside of the pipeline and each chamber, ensures the vacuum degree, so that the boiling point of the drug liquid is lowered and the high-temperature steam consumption is lower.
