Abstract

This utility model discloses a distillation assembly for a distillation column, comprising several vertically arranged trays, each with rounded sides and parallel edges, and flat sections at their disjointed ends for overflow. The rounded sections of the trays are fixedly connected to the inner wall of the distillation column. Overflow plates and guide plates are respectively provided at the upper and lower ends of the flat sections of the trays. Several adjustment structures are included, each comprising several meshing grooves (first and second teeth). The height of the overflow plate is adjusted by the meshing of grooves (second and third teeth) with different grooves (first and third teeth). Several float valves are evenly distributed on the upper surface of the trays. This utility model allows adjustment simply by operating a lever to disengage groove (second and third teeth) from its meshing groove (first and third teeth), sliding the overflow plate to a suitable height, and then engaging groove (second and third teeth) with the corresponding groove (first tooth). This structure enables control of the overflow plate height according to different distillation conditions, thereby controlling the overflow rate and the liquid layer thickness on the trays.

Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a distillation component of a distillation column. Background Technology

[0002] A distillation column is a device used to separate different components in a liquid mixture, widely used in industries such as chemical engineering, petroleum refining, and food processing. Its basic principle is based on the different boiling points of the components in the liquid mixture. By heating one component to boiling, then evaporating and condensing it for recovery, separation is achieved. A distillation column typically consists of a column body, trays, a reboiler, and a condenser. The column body contains several trays, each with a contact area between liquid and vapor. Through special tray design, sufficient contact between vapor and liquid is ensured, thereby improving separation efficiency. As the core equipment in the distillation process, the performance of the internal distillation components directly affects the distillation effect and efficiency.

[0003] The existing technology still has some problems: the height of the overflow plate is usually fixed and it is difficult to adjust it flexibly according to actual production needs. This makes it impossible to control the overflow rate of the liquid and the thickness of the liquid layer on the plate under different distillation conditions, thus affecting flexibility and convenience.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a distillation component for a distillation column.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A distillation assembly for a distillation column includes several vertically arranged trays, the adjacent sides and side edges of which are rounded, and the distancing ends are cut into flat sections for overflow. The rounded portions of the trays are fixedly connected to the inner wall of the distillation column. Overflow plates and guide plates are respectively provided at the upper and lower ends of the flat sections of the trays. Several adjustment structures are provided, each including several meshing grooves 1 and 2, which engage with each other in different grooves 1 to adjust the height of the overflow plates. Several float valves are evenly arranged on the upper surface of the trays.

[0008] As an improvement, the adjustment structure also includes an adjustment plate, which is fixedly connected to the upper flat end of the tray, and the guide plate is fixedly connected to the lower end of the adjustment plate. The sides of the adjustment plate and the guide plate are both fixedly attached to the inner wall of the distillation column.

[0009] As an improvement, the adjusting plate has an adjusting groove inside, the overflow plate slides and fits inside the adjusting groove, the upper end and both sides of the adjusting groove are open, and the side of the overflow plate is provided with a sealing strip, which slides and fits against the inner wall of the distillation column to form a seal.

[0010] As an improvement, the first tooth groove is vertically and evenly opened on the opposite sides of the front and rear overflow plates. The opposite ends of the front and rear adjustment plates are each opened with a through groove communicating with the adjustment groove. An insert rod is provided in the through groove, and the front and rear ends of the insert rod pass through the through groove. The second tooth groove is opened at the end of the insert rod close to the first tooth groove.

[0011] As an improvement, the upper and lower ends of the insertion rod are provided with sliding grooves on the adjustment plate. The upper and lower ends of the insertion rod slide in the sliding grooves at the upper and lower ends, respectively. The insertion rod and the end of the sliding groove away from the second tooth groove are connected by a telescopic rod. A spring is sleeved on the outside of the telescopic rod. The two ends of the spring are fixedly connected to the insertion rod and the inner wall of the sliding groove, respectively.

[0012] As an improvement, the upper end of the tower plate has several through holes, the lower end of the float valve is fixedly connected to an internally hollow threaded pipe, the threaded pipe is threaded into the through holes, and the upper end of the float valve has several overflow holes communicating with the threaded pipe.

[0013] As an improvement, the surface of the float valve is coated with a composite photocatalytic coating.

[0014] The advantages of this invention compared to the prior art are as follows: when it is necessary to adjust the height of the overflow plate, simply operate the insert rod to disengage the second tooth from the currently engaged first tooth, slide the overflow plate to the appropriate height, and then engage the second tooth with the corresponding first tooth to complete the adjustment. This structure can control the height of the overflow plate according to different distillation conditions, thereby controlling the overflow rate of the liquid and the thickness of the liquid layer on the tray, improving flexibility and convenience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Combined with appendix Figures 1-4 As shown, this utility model discloses a distillation assembly for a distillation column, including several vertically arranged trays 1. The adjacent sides and side edges of the trays 1 are round, and the distancing ends are cut into flat sections for overflow. The round parts of the trays 1 are fixedly connected to the inner wall of the distillation column. Overflow plates 2 and guide plates 3 are respectively provided at the upper and lower ends of the flat sections of the trays 1. Several adjustment structures are provided, including several meshing grooves 1 4 and grooves 2 5. The height of the overflow plates 2 is adjusted by the meshing of grooves 2 5 with different grooves 1 4. Several float valves 6 are evenly arranged on the upper end of the trays 1.

[0023] Next, the adjustment structure also includes an adjustment plate 7, which is fixedly connected to the upper flat end of the tray 1. The guide plate 3 is fixedly connected to the lower end of the adjustment plate 7. The sides of the adjustment plate 7 and the guide plate 3 are both fixedly connected to the inner wall of the distillation column. An adjustment groove 8 is opened inside the adjustment plate 7. The overflow plate 2 slides in the adjustment groove 8. The upper end and both sides of the adjustment groove 8 are open. The side of the overflow plate 2 is provided with a sealing strip and slides in the inner wall of the distillation column to form a seal and prevent liquid leakage.

[0024] Furthermore, the first tooth groove 4 is vertically and evenly opened on the opposite sides of the front and rear overflow plates 2. The opposite ends of the front and rear adjustment plates 7 are each opened with a through groove 9 that communicates with the adjustment groove 8. An insert rod 10 is installed in the through groove 9. The front and rear ends of the insert rod 10 pass through the through groove 9. The second tooth groove 5 is opened at the end of the insert rod 10 near the first tooth groove 4. The upper and lower ends of the insert rod 10 are each provided with a sliding groove 11 opened on the adjustment plate 7. The upper and lower ends of the insert rod 10 slide in the sliding groove 11 at the upper and lower ends, respectively. The end of the insert rod 10 away from the second tooth groove 5 is connected by a telescopic rod 12. A spring 13 is sleeved on the outside of the telescopic rod 12. The two ends of the spring 13 are respectively fixedly connected to the inner wall of the insert rod 10 and the sliding groove 11.

[0025] Therefore, in practice, when it is necessary to adjust the height of the overflow plate 2, pull the insert rod 10 outward to make the insert rod 10 slide in the slide groove 11 and compress the spring 13. At this time, the second tooth groove 5 disengages from the meshing with the first tooth groove 4. Then, slide the overflow plate 2 up and down along the adjustment groove 8 to the required height, release the insert rod 10, and under the elastic force of the spring 13, the insert rod 10 moves towards the first tooth groove 4, so that the second tooth groove 5 meshes with the first tooth groove 4 of the corresponding height, thereby fixing the position of the overflow plate 2 and completing the height adjustment. It is simple, quick and highly flexible.

[0026] Finally, the upper end of the tray 1 has several through holes 14, and the lower end of the float valve 6 is fixedly connected to an internally hollow threaded tube 15. The threaded tube 15 is threaded into the through holes 14. The upper end of the float valve 6 has several overflow holes 16 that communicate with the threaded tube 15. When installing the float valve 6, align the threaded tube 15 with the through holes 14, rotate the float valve 6, and make the threaded tube 15 threadedly connected to the through holes 14 to complete the installation. When disassembling, rotate the float valve 6 in the opposite direction to unscrew the threaded tube 15 out of the through holes 14, so as to facilitate individual replacement and maintenance.

[0027] The surface of the float valve 6 is coated with a composite photocatalytic coating. This coating can decompose organic matter and contaminants adhering to the surface of the float valve 6 into harmless substances such as carbon dioxide and water, thereby preventing scale and blockage of the float valve 6, maintaining the ventilation and overflow performance of the float valve 6, extending the service life of the float valve 6, and also helping to improve the mass and heat transfer effect of the gas and liquid phases at the float valve 6, thereby improving the distillation efficiency.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
