Description

TECHNICAL FIELD

[0002] In organic synthesis processing, the material needs to be rectified and then introduced into the reboiler for further processing. Trace amounts of salt in the rectified material are enriched in the reboiler during continuous rectification and settle down. When the accumulation is large, it affects the heat transfer of the reboiler and is difficult to clean, which affects the use effect of the reboiler.

[0003] After searching, the patent document with the publication number CN219110833U discloses a reboiler. The reboiler is connected to a distribution pipe at the upper end of the heat exchange pipe. The distribution pipe is provided with overflow holes. The liquid medium first enters the upper pipe box. When the liquid medium level is higher than the overflow hole, the liquid medium enters the distribution pipe from the overflow hole and then enters the heat exchange pipe. This can reduce the flow rate of the liquid medium, improve the heat exchange efficiency, and improve the vaporization effect of the liquid medium. The upper pipe box is connected to a liquid blocking cylinder around all the distribution pipes to prevent the liquid medium entering the pipe inlet from directly entering the distribution pipe.

[0004] However, the above-mentioned reboiler is still the original heat natural circulation reboiler, and the salt in the rectification process cannot be effectively cleaned, which reduces the reboiling effect. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] In order to make the technical personnel in the art better understand the technical scheme of the present application, the drawings needed in the embodiments will be briefly introduced below, obviously, the drawings described below are only some embodiments described in the present application, and other drawings can also be obtained according to these drawings for those skilled in the art.

[0025] The embodiment of the present application discloses a device for reducing the influence of salt in a reboiler.

[0026] Embodiment 1

[0027] The present application provides a device for reducing the influence of salt in a reboiler as shown in Figures 1-3 The device for reducing the influence of salt in a reboiler comprises a reboiler 1, a first flow guide pipe 2 and a second flow guide pipe 3, characterized in that the first flow guide pipe 2 is in communication with the reboiler 1, the first flow guide pipe 2 and the second flow guide pipe 3 are fixedly provided with support plates 4 at one end close to each other, the side walls of the two support plates 4 are fixedly provided with positioning blocks 5, the two sides of the two positioning blocks 5 are jointly provided with two symmetrical reverse osmosis membrane filters 6, and the pipe wall of the first flow guide pipe 2 is fixedly provided with a forced circulation pump 20.

[0028] Both ends of the reverse osmosis membrane filter 6 are connected to connecting pipes 7, which are connected to positioning blocks 5. Both sides of the positioning blocks 5 are provided with connecting grooves 11. The pipe openings of the connecting pipes 7 are inserted into the connecting grooves 11. A second connecting flange 12 is provided between the connecting pipes 7 and the positioning blocks 5. A fixed pipe 8 is provided on the pipe wall of the connecting pipes 7. The pipe openings of the first guide pipe 2 and the second guide pipe 3 are rotatably connected to guide pipes 9. The pipe wall of the guide pipe 9 is rotatably engaged with the interior of the first guide pipe 2 through a sealed bearing. The end of the guide pipe 9 near the reverse osmosis membrane filter 6 is connected to the fixed pipe 8 through the first connecting flange 10.

[0029] When the reboiler 1 is in use, the two guide pipes 9 are connected to the lower fixed pipe 8, so that the lower reverse osmosis membrane filter 6 can be used. During reboiling, the material can be stably fed into the reboiler 1 for processing by the forced circulation pump 20. During the material flow, the internal filtration components of the reverse osmosis membrane filter 6 can effectively block the salt in the material, minimizing the impact of salt on the stable operation of the reboiler 1. After the lower reverse osmosis membrane filter 6 has been used for a long time, the guide pipes 9 can be connected to the upper fixed pipe 8, so that the upper reverse osmosis membrane filter 6 can be used. This facilitates the material flow at the top, while the lower filter can be disassembled and its internal filtration components can be cleaned, ensuring continuous and stable filtration.

[0030] Example 2

[0031] Example 2, based on Example 1, aims to precisely adjust the movement of the two guide tubes 9, such as... Figures 1-2 As shown, a mounting plate 13 is fixedly provided on the back side of the positioning block 5, and a mounting bracket 14 is fixedly provided on the surface of the mounting plate 13. An adjusting screw 15 is rotatably passed through the side of the mounting bracket 14. A push plate 16 is threaded on the rod wall of the adjusting screw 15. The cross-section of the push plate 16 is arranged in a "+" shape. Both sides of the inside of the push plate 16 are provided with strip holes. A push rod 17 slides through the strip holes. A limiting plate 19 is fixedly provided at the front end of each of the two push rods 17. The limiting plate 19 covers the outside of the strip holes. The push rod 17 is fixedly connected to the guide tube 9. A crank handle 18 is fixedly provided at the end of the adjusting screw 15.

[0032] Before switching between the two reverse osmosis membrane filters 6, the first connecting flange 10 can be disassembled and the crank handle 18 can be turned so that the adjusting screw 15 rotates and drives the push plate 16 to move. During this process, the strip hole pushes the push rod 17, so that the push rod 17 drives the guide tube 9 to rotate under the movement limit of the limiting plate 19, so that the opening of the guide tube 9 can be connected with the upper fixed tube 8, thereby completing the precise matching connection between the guide tube 9 and the reverse osmosis membrane filter 6.

[0033] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
