[0029] Embodiment 3:
[0030] Please refer to Figures 1 - 3, which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. Before the utility model is used, 120°C heat-conducting oil is introduced into the outer jacket 11, 90°C hot water is introduced into the coil 13, and 70°C hot water is introduced into the inner jacket 12. When separation is carried out, a vacuum is pumped at the vacuum pipe orifice 114, and the material is fed from the feed port 26 and enters the primary separation chamber 16.

The vaporized material with a boiling point below 90°C enters the tertiary separation chamber 18 through the second air hole 19 of the inner jacket 12 under the action of vacuum pumping. The material with a boiling point above 70°C liquefies and flows out through the intermediate material outlet 117. The remaining gas enters the inner side of the lower cylinder 25 through the third air hole 210 and is discharged to the tail gas treatment system of the factory area through the vacuum pipe orifice 114. The extremely small amount of remaining material is collected at the drain port 118. The present invention is provided with three separation chambers. The temperature of the primary separation chamber 16 is affected by the outer jacket 11, the temperature of the secondary separation chamber 17 is affected by the coil 13, and the temperature of the tertiary separation chamber 18 is affected by the inner jacket 12. In this way, the temperatures of the three separation chambers are different, and the material can be heated three times, so that materials with different boiling points vaporize to achieve separation. Only one feeding is required to separate the intermediate, optimizing the process flow. Moreover, the material does not need to enter multiple devices and pipelines, improving the purity of the product.
