DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] This embodiment provides a rectification column, which is more conducive to realizing the continuous distillation and recovery treatment of a large amount of ethanol mixed solution. Specifically, as Figures 1-4 shown, it includes a tower body 1, a connecting cylinder 2, an electric push rod 3 and a ventilation pipe 4. The tower body 1 further includes a first distillation tower 11, a second distillation tower 12 and a condensation tower 13. The first distillation tower 11 is arranged between the second distillation tower 12 and the condensation tower 13. The surfaces of the first distillation tower 11 and the second distillation tower 12 are respectively provided with a mixed solution inlet and a mixed solution outlet. The surface of the condensation tower 13 is provided with an ethanol outlet and an exhaust gas outlet. A plurality of heating pipes 10 are arranged in the first distillation tower 11. Part of the surfaces of the plurality of heating pipes 10 penetrate through the bottom surface of the first distillation tower 11 and protrude into the second distillation tower 12. Openings 111 are respectively formed through the left and right sides of the bottom surface of the first distillation tower 11. Two empty slots 121 are formed through the surface of the second distillation tower 12. Two fixing plates 122 are arranged on the surface of the second distillation tower 12. The connecting cylinder 2 is located in the second distillation tower 12. A first convex plate 21 and a second convex plate 22 are arranged on the surface of the connecting cylinder 2. The first convex plate 21 protrudes out of the second distillation tower 12 through the empty slot 121. A convex rod 221 is arranged vertically on the top surface of the second convex plate 22. The top end of the convex rod 221 protrudes into the opening 111. The electric push rod 3 is installed on the surface of the fixing plate 122. The output end of the electric push rod 3 is in an extended state. The output end of the electric push rod 3 is fixedly connected to the bottom surface of the first convex plate 21. The ventilation pipe 4 is arranged between and communicated with the first distillation tower 11, the second distillation tower 12 and the condensation tower 13. An induced draft fan is installed on the ventilation pipe 4, so that the first distillation tower 11 and the second distillation tower 12 can realize the rotation heating and distillation treatment of the mixed solution, and the continuity of the distillation processing is stronger, which is more conducive to realizing the efficient treatment of the ethanol mixed solution.

[0025] As Figures 2-4 shown, in this embodiment, one end of the convex rod 221 protrudes into the first distillation tower 11 through the opening 111. The end of the convex rod 221 away from the second convex plate 22 is designed as a semicircle, so as to avoid the residue of part of the mixed solution when the mixed solution in the first distillation tower 11 flows into the second distillation tower 12 through the opening 111.

[0026] AsFigures 1-4 As shown, in this embodiment, the connecting cylinder 2, the second convex plate 22, and the convex rod 221 are all made of a heat-conducting metal. An insulating sponge 5 is provided in the empty slot 121 opened in the second distillation column 12. The diameter of the insulating sponge 5 is adapted to the diameter of the empty slot 121. Thus, the heat-conducting effect of heat can be effectively achieved by using the connecting cylinder 2, the second convex plate 22, and the convex rod 221, so that the first distillation column 11 or the second distillation column 12 can always maintain a high temperature state, which is more conducive to realizing the subsequent heating treatment of the mixed solution entering the first distillation column 11 or the second distillation column 12 respectively.

[0027] As Figure 3 shown, in this embodiment, the connecting cylinder 2 is designed with a hollow cylindrical structure. There is a space between the outer surface of the connecting cylinder 2 and the inner surface of the second distillation column 12, so that the connecting cylinder 2 can avoid direct contact and friction with the inner surface of the second distillation column 12 during the movement process, preventing wear and affecting the heat-conducting effect.

[0028] As Figures 1-3 shown, a third convex plate 6 is provided on the surface of the second distillation column 12. A maintenance window 123 is opened on the surface of the second distillation column 12. A sealing plate 7 is provided in the maintenance window 123. A fourth convex plate 71 is provided on the surface of the sealing plate 7. A fixing bolt 8 is provided between the third convex plate 6 and the fourth convex plate 71. Two handles 72 are provided on the surface of the sealing plate 7. The diameter of the maintenance window 123 is adapted to the diameter of the connecting cylinder 2, so that the sealing plate 7 can be separately disassembled from the second distillation column 12, which is more conducive for the staff to clean or replace and overhaul the internal structure of the second distillation column 12 through the maintenance window 123.

[0029] During the use of the above-mentioned rectifying column, the mixed solution is introduced into the first distillation column 11 through the mixed solution inlet, and the heating pipe 10 is used to heat the mixed solution, so that the ethanol contained in the mixed solution evaporates into gas after being heated. The induced draft fan is started, and it enters the condensation tower 13 through the ventilation pipe 4 for condensation. After the mixed solution in the first distillation column 11 is preliminarily treated, the electric push rod 3 is started, and the output end of the electric push rod 3 retracts, thereby driving the connecting cylinder 2, the second convex plate 22 and the convex rod 221 to move downward simultaneously, so that the distance between the convex rod 221 and the opening 111 increases. The mixed solution in the first distillation column 11 enters the second distillation column 12. Subsequently, another mixed solution is introduced into the first distillation column 11 again, and the heating pipes 10 are used to heat the mixed solutions in the first distillation column 11 and the second distillation column 12 respectively. The ethanol vapor evaporated from the heated mixed solution in the second distillation column 12 still enters the condensation tower 13 through the ventilation pipe 4. When the mixed solution in the second distillation column 12 is reheated, the mixed solution outlet can be opened to discharge it. Then, the staff can again pass the above operation to introduce the mixed solution in the first distillation column 11 into the second distillation column 12 and cycle according to the above operation steps, so as to realize the efficient treatment of the ethanol mixed solution.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
