[0026] The working principle of this utility model:

[0027] Refer to the instruction manual Figure 1-Figure 5The utility model is provided with a separation bottle 11, a circulation plug 13, a liquid delivery channel 15, an air outlet 16, an air outlet pipe 17 and a temperature control valve 19. The operator delivers the liquid to be treated to the liquid delivery channel 15 inside the separation bottle 11 through the liquid delivery pipe 14. At this time, the discharge port 2 is in a closed state, and the liquid to be treated stays in the liquid delivery channel 15. A medium (gas or liquid) of a certain temperature is delivered to the separation bottle 11. The medium and the liquid to be treated in the separation bottle 11 are heat exchanged, and the liquid to be treated can be effectively heated. The spiral liquid delivery channel 15 makes the liquid to be treated The heating is more uniform and stable.

The liquid to be treated is heated uniformly, and the structural design is relatively simple, the cost is low, and there are fewer structures in contact with the liquid to be treated and the gasified gas, which can effectively ensure the service life of the device. The injected medium can be temperature-controlled by the temperature control valve 19, and the type of evaporated gas can be determined according to the heating temperature to achieve the separation treatment of the low-boiling-point liquid to be treated. The liquid with a lower boiling point is vaporized from the liquid to be treated and then passes through the outlet hole 16 and is discharged from the outlet pipe 17. The spherical cavity 1301 The gasified gas in the liquid delivery channel 15 is buffered inside the air outlet 16 inside the circulation plug 13, and the gasified gas first enters the spherical cavity 1301, and then enters the air outlet pipe 17 from the air outlet 16; after the liquid delivery pipe 14 fills the liquid delivery channel 15 with the liquid to be treated, the liquid to be treated inside the liquid delivery channel 15 moves upward from the air outlet 16, and after the liquid to be treated enters the spherical cavity 1301, the liquid to be treated pushes the floating plate 1302 upward, the floating plate 1302 pushes the plunger 1303 upward, and the plunger 1303 seals the air outlet 16, which can It effectively prevents the liquid to be treated from overflowing and discharging from the air outlet 16 due to accidental filling, thereby ensuring the safety of the equipment during operation; after the gasified gas in the liquid to be treated enters the spherical cavity 1301 of the air outlet 16, the gas lifts the floating plate 1302, and the plunger 1303 moves upward along with the floating plate 1302, and the plunger 1303 located below is separated from the air outlet 16.

The operator can deliver the mixed solution to be separated into the separation bottle 11 through the liquid delivery pipe 14 to separate the mixed solution;

[0029] The liquid delivery channel 15 is spiral-shaped, and extends along the length direction of the separation bottle 11 from the top of the separation bottle 11 to the bottom of the separation bottle 11; an air outlet hole 16 is vertically penetrated on the top wall of the circulation plug 13, and an air outlet pipe 17 is provided on the inner wall of the air outlet hole 16. A temperature control port 18 is penetrated on the side wall of the separation bottle 11, and a temperature control valve 19 is fixedly installed on the inner wall of the temperature control port 18. The temperature control valve 19 is an airtight valve. The operator injects a solution of a certain temperature into the separation bottle 11 through the temperature control valve 19, so that the solution inside the separation bottle 11 and the mixed solution inside the liquid delivery channel 15 generate heat exchange, and then the mixed solution in the liquid delivery channel 15 is heated, so that the mixed solution with a lower boiling point in the mixed solution is vaporized and discharged from the air outlet pipe 17;

[0030] When in use, the operator first adds the mixed solution to be separated into the liquid delivery channel 15 from the feed port 12, then opens the temperature control valve 19, and injects a solution of a certain temperature into the separation bottle 11. At the same time, the temperature sensor 31 monitors the temperature in the separation bottle 11 in real time. At this time, the low-boiling-point liquid in the mixed solution will be vaporized and discharged from the air outlet pipe 17. After liquefaction and condensation on the bottom wall of the condensation tank 33, it falls from the condensation tank 33. The operator collects the fallen liquid, and the remaining liquid enters the collection bottle 22 based on the solution temperature in the separation bottle 11 for subsequent separation or reuse.
