[0002] Both the kettle and the tower are equipment in a chemical plant. The kettle is like a cooking pot and the tower is like an ordinary tower. The tower kettle is a combination of the two. It is a high tower with basically the same structure at each level. It has the dual functions of a tower and a kettle. The short tower kettle is a type of tower kettle, and the distillation unit is one of the main structures of the short tower kettle. The distillation unit has the advantages of simple operation, stable structure and good use effect in actual use.

[0003] The prior art discloses a tower-bottom composite distillation device with announcement number: CN206980140U, which includes a still, a heater, a liquid level gauge, a vaporization chamber, a superheater, a first heating steam inlet, a first condensed water outlet, a temperature measuring hole, a feed port, a sewage outlet, a manhole, a second heating steam inlet, a secondary steam outlet, and a second condensed water outlet. The mother liquor enters the still through the feed port, is vaporized into secondary steam by the heater, and then enters the packing section. The packing captures the entrained liquid droplets and enters the superheating section. After being heated again into superheated secondary steam by the superheating section, it is discharged from the tower top outlet. The heat source for vaporization and superheating comes from the primary steam, which is divided into two parts. One part enters from the heater inlet in the still, and condensed water is discharged from after heat exchange; the other part enters from the superheater inlet, and condensed water is discharged from after heat exchange.

[0004] In the above utility model, the mother liquor enters the interior of the distillation kettle through the feed pipe and needs to be heated by a heater. The heating pipe of the heater is fixed in position, and the position where the mother liquor contacts the heating pipe can be quickly heated up, but the mother liquor at other positions with normal temperature needs to wait for heat transfer. This waiting process takes a long time, which reduces the working efficiency of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
