[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] During specific implementation: As Figures 1-5 shown, a rectifying tower capable of flexibly adjusting the side stream oil components includes a rectifying tower body 1, a support frame 5 and a preheater 3: A preheater 3 is arranged on the side of the rectifying tower body 1, a support frame 5 is arranged at the lower end of the rectifying tower body 1, and a temperature adjustment structure 20 is arranged on the side of the preheater 3;

[0024] The temperature adjustment structure 20 includes a heating shell 9, a heating pipe 11 and an operation panel 10. A heating shell 9 is arranged on the surface of the preheater 3, a heating pipe 11 is arranged inside the heating shell 9, and an operation panel 10 is arranged on the side of the heating shell 9;

[0025] When the device is in use, when side stream oil with different components is required, the temperature of the feed needs to be adjusted at this time. First, the heating pipe 11 is turned on through the operation panel 10, and the operation panel 10 adjusts the temperature to the required temperature. Subsequently, the heating pipe 11 heats the material inside the liquid inlet pipe 2 inside the preheater 3, so as to change the temperature of the material entering the rectifying tower body 1, thereby changing the separation effect of each component in the tower, and obtaining side stream oil with different components.

[0026] A liquid inlet pipe 2 is arranged on the side of the rectifying tower body 1. The liquid inlet pipe 2 penetrates through the preheater 3, and a first electric valve 4 is arranged on the surface of the liquid inlet pipe 2;

[0027] When the device is in use, when side stream oil with different components is required, while adjusting the temperature, the flow rate of the material entering can also be changed to change the components of the side stream oil. At this time, the operation panel 10 is used to adjust the opening and closing of the first electric valve 4 to change the flow rate entering the liquid inlet pipe 2.

[0028] At the lower end of the rectification column body 1, there is a liquid outlet 6, and a second electric valve 7 is arranged on the surface of the liquid outlet 6. The liquid outlet 6 penetrates through the second electric valve 7;

[0029] When the device is in use, after separating the materials, the second electric valve 7 is opened through the operation panel 10 to discharge the rectified materials from the liquid outlet 6.

[0030] A connecting pipe 8 is arranged on the side of the rectification column body 1, and a ventilation pipe 12 is arranged at the upper end of the rectification column body 1;

[0031] A support plate 19 is arranged on the side of the rectification column body 1. A condenser 13 is arranged at the upper end of the support plate 19, and a vacuum pump 14 is arranged at the upper end of the condenser 13. One end of the ventilation pipe 12 is connected to the condenser 13;

[0032] A drain pipe 21 is arranged on the side of the condenser 13, and a reflux pipe 15 is arranged at the lower end of the condenser 13. One end of the reflux pipe 15 is connected to the rectification column body 1;

[0033] When the device is in use, the bottom of the tower is heated through a reboiler connected externally by the connecting pipe 8 to make the liquid with a lower boiling point in the materials form gas and move upward. At this time, the vacuum pump 14 is turned on, and the vacuum pump 14 creates suction in the ventilation pipe 12 to suck the vaporized liquid inside the rectification column body 1 into the condenser 13. At this time, the vaporized liquid is cooled by the condenser 13 to turn the vaporized liquid back into a liquid state. Subsequently, the liquid is discharged through the drain pipe 21. At this time, the condensed water generated by the condensation of the condenser 13 enters the reflux pipe 15 and then re-enters the rectification column body 1 to provide cold reflux on the tray 16, remove the excess heat in the tower, maintain the heat balance in the tower, and further increase the separation accuracy of the product through repeated condensation and vaporization.

[0034] Trays 16 are arranged inside the rectification column body 1. Overflow plates 17 are arranged on the sides of the trays 16, and bubble caps 18 are arranged at the upper ends of the trays 16;

[0035] The drain pipe 21 penetrates through the condenser 13;

[0036] When the device is in use, first, the materials enter the rectification column body 1 through the inlet pipe 2 and fall onto the surface of the tray 16. At this time, water is continuously injected, and a certain liquid level is formed through the overflow plate 17 to make the gas and liquid come into close contact through the bubble cap 18 to promote the mass transfer between them. Subsequently, when the liquid level is higher than the overflow plate 17, the liquid enters the next tray 16. By arranging multiple trays 16, the liquid can be separated sufficiently.

[0037] When the utility model is in use, first, the opening amount of the first electric valve 4 and the heating temperature of the heating pipe 11 are regulated through the operation panel 10. Subsequently, through the liquid inlet pipe 2, the material passes through the inside of the first electric valve 4 and the preheater 3 to regulate the flow rate and temperature. Then, the material enters the inside of the rectification tower body 1 and falls onto the surface of the tray 16. Subsequently, the reboiler is externally connected through the connecting pipe 8 to heat the bottom of the tower to promote the separation of the material. Then, for the rectified material, the second electric valve 7 is opened to discharge the material through the liquid outlet 6.

[0038] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
