The heat exchanger 3 is connected between the evaporation tank 1 and the condensation tank 2; a heating pipeline 41 is arranged in the evaporation tank 1, and a refrigerant circuit pipeline 5 is connected between the heating pipeline 41 and the heat exchanger 3. The refrigerant circuit pipeline 5 is connected to the refrigerant inlet 31, the refrigerant outlet 32 of the heat exchanger 3, and the heating pipeline 41. A first vacuum pumping assembly 14 is arranged on the evaporation tank 1, and a second vacuum pumping assembly 23 is arranged on the condensation tank 2. The first vacuum pumping assembly 14 and the second vacuum pumping assembly 23 respectively evacuate the evaporation tank 1 and the condensation tank 2.

[0043] The first vacuum pumping assembly 14 evacuates the evaporation tank 1, and the second vacuum pumping assembly 23 evacuates the condensation tank 2; the stock solution can boil and evaporate when it reaches 35 - 50 degrees under a vacuum state, and the refrigerant enters the heating pipeline 41 to heat the stock solution to generate steam; and the first vacuum pumping assembly 14 and the second vacuum pumping assembly 23 alternately evacuate the evaporation tank 1 and the condenser tube, and use the pressure difference to drive the steam to pass through the steam pipeline 4 and enter the condensation tank 2 for cooling and condensation; avoiding high-temperature heating, effectively saving energy.

[0044] Please refer to the appendix Figure 1 , appendix Figure 1It is a structural schematic diagram of a conventional waste reduction device for emulsion, which includes a condenser dish d, a heater b, a kerosene tank c, a condenser dish d, an ice water machine e, and a circulation pump system f for pumping waste emulsion. During the waste reduction process, the waste emulsion enters the condenser dish d, the heater b heats the kerosene in the kerosene tank c, the heated kerosene is pumped into the condenser dish d by the circulation pump system f to heat the waste emulsion. After the emulsion is heated, steam is generated and goes upward through the pipeline into the condenser dish d, and the ice water machine e cools the steam in the condenser dish d. The waste slurry after heating and evaporation is discharged from the condenser dish d for collection. In this embodiment, structures such as the kerosene tank c and the ice water machine e are avoided, making the overall structure compact and effectively reducing the size of the overall system layout space.

[0045] In this embodiment, the refrigerant circuit pipeline 5 includes a front pipeline 51 and a rear pipeline 52. The first end of the front pipeline 51 is connected to the refrigerant outlet 32, and the other end of the front pipeline 51 is connected to one end of the heating pipeline 41.

The compressor 511 and the expansion valve 512 on the front pipeline 51 control the refrigerant to enter the heating pipeline 41. After heating is completed, the refrigerant enters the air condenser 522 located on the rear pipeline 52. The air condenser 522 cools the refrigerant, and the cooled refrigerant is driven by the compressor 511 and the expansion valve 512 again to enter the heating pipeline 41 for heating. This cycle repeats to recycle the refrigerant and reduce costs.

[0046] In this embodiment, a condensate water circuit pipeline 6 is connected between the condensate tank 2 and the heat exchanger 3. A circulation pump 61 is provided on the condensate water circuit pipeline 6. The condensate water circuit pipeline 6 is connected between the condensate water inlet 33 and the condensate water outlet 34 of the condensate tank 2 and the condensate water inlet 33 and the condensate water outlet 34 of the heat exchanger 3. The condensate water exchanges heat with the steam in the condensate tank 2, causing the steam to liquefy and the temperature of the condensate water to rise. The circulation pump 61 drives the heated condensate water into the heat exchanger 3. The condensate water passage in the heat exchanger 3 is located on one side of the refrigerant passage. The refrigerant is used to cool the heated condensate water. The circulation pump 61 drives the cooled condensate water to enter the condensate tank 2 again to exchange heat with the steam, recycling the condensate water and further reducing costs.

[0047] The steam outlet 13 is arranged at the top of the evaporation tank 1, facilitating the smooth entry of steam into the steam pipeline 4 after rising. A foam sensor 20 and an antifoaming agent inlet 15 are also provided at the top of the evaporation tank 1. The antifoaming agent inlet 15 is communicated with an external antifoaming agent container 9. In this embodiment, the antifoaming agent inlet 15 is communicated with the external antifoaming agent container 9 through a pipeline, and an antifoaming agent inlet liquid valve 19 is arranged on the pipeline to control the opening and closing of the antifoaming agent inlet 15. The stock solution boils to generate foam, and as the heating time increases, the amount of generated foam rises. The accumulated foam moves towards the steam outlet 13. The foam sensor 20 detects the foam. When the foam accumulates to the steam outlet 13, it controls the antifoaming agent to enter the evaporation tank 1 through the antifoaming agent inlet 15 to defoam the foam, preventing the stock solution from entering the condensation tank 2 and improving the waste reduction effect of the stock solution.

The second channel of the three-way valve 17 is communicated with an external concentrated liquid container 8. The diaphragm pump 16 is connected between the evaporation tank 1 and the third channel of the three-way valve 17. The diaphragm pump 16 pumps out the stock solution into the external concentrated liquid container 8 for recovery.

[0050] Specifically, a water outlet 35 and a water replenishment port 22 are respectively opened on the heat exchanger 3 and the condensation tank 2. When the use is completed, the heat exchanger 3 discharges the condensed water inside through the water outlet 35; the condensation pipe replenishes the condensed water inside through the water replenishment port 22.
