Moreover, replacing or modifying the distillation tower often involves the suspension and adjustment of the production line, which will undoubtedly have an adverse effect on the continuity and stability of production.

[0031] In view of the above problems, the embodiments of the present application provide an improved high-efficiency distillation tower, which can be flexibly connected to different steam sources, is easy to disassemble, and can also enhance the sealing of the connection, effectively preventing the leakage of steam or liquid.

[0032] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0033] Figure 1 It is a stereoscopic diagram of the overall structure of an improved high-efficiency fractionation tower shown in an embodiment of the present application;

[0034] See also Figure 1-Figure 5An improved high-efficiency fractionation tower comprises a tower body 1, wherein the tower body 1 comprises a tower top 2 and a tower bottom 3, wherein the tower top 2 and the tower bottom 3 are connected via a first connecting mechanism 4, wherein the first connecting mechanism 4 is provided to ensure the stability of the tower body 1, and also facilitate the installation and maintenance of the equipment, wherein a second connecting mechanism 5 is provided at the bottom of the tower bottom 3, wherein the second connecting mechanism 5 is provided to facilitate the user to connect the equipment to different steam sources, so that the user is no longer restricted to a specific steam source, wherein the second connecting mechanism 5 comprises a first flange 501, a block 502, a mounting groove 503 and a first sealing rubber ring 504, wherein the first flange 501 is fixedly installed at the middle position of the bottom of the tower bottom 3, wherein the first flange 501 and the block 502 are provided to make the installation process simple and quick, wherein the block 502 is fixedly installed at the bottom of the flange 501, the mounting groove 503 is provided on the outer side of the block 502, the first sealing rubber ring 504 is sleeved on the inner side of the mounting groove 503, and the first sealing rubber ring 504 enhances the sealing effect of the connection.

[0035] In one embodiment, a steam inlet 6 is provided at the bottom of the tower bottom 3, and the steam inlet 6 allows steam to enter the tower bottom 3. The block 502 is ring-shaped, and a partition 7 is fixedly installed in the inner cavity of the tower bottom 3. The surface of the partition 7 has pores 8 evenly distributed. The partition 7 is used to disperse the steam so that it can evenly enter the tower body 1 through the pores 8, which helps to improve the distillation efficiency and ensure the uniformity of the distillation process.

[0036] In one embodiment, a kettle liquid outlet 9 is provided on one side of the tower bottom 3, and the kettle liquid outlet 9 is located above the partition 7. A support plate 10 is fixedly installed on the outer side of the tower bottom 3, and a support rod 11 is fixedly installed on the bottom of the support plate 10. The support plate 10 and the support rod 11 can provide sufficient supporting force, thereby reducing the impact of external forces on the tower body 1.

[0037] In one embodiment, the first connecting mechanism 4 includes a second upper flange 401, a second lower flange 402, a slot 403, an insert 404, a fixing slot 405 and a second sealing rubber ring 406. The second upper flange 401 is fixedly installed at the bottom of the tower top 2, and the second lower flange 402 is fixedly installed at the top of the tower bottom 3. The second upper flange 401 cooperates with the second lower flange 402 to form a stable connection structure to ensure that the tower top 2 and the tower bottom 3 can be tightly docked to prevent loosening or dislocation caused by vibration or external force. The slot 403 is opened at the top of the second lower flange 402. The slot 403 is used to accommodate the insert 404 and form a tight fit with it, which can ensure that the tower top 2 and the tower bottom 3 have a precise docking position in the vertical direction and provide sufficient friction to prevent relative sliding.

[0038] In one embodiment, the plug block 404 is fixedly installed at the bottom of the second upper flange 401 and plugged into the inner side of the slot 403. The fixing slot 405 is opened on the outer side of the plug block 404. The second sealing rubber ring 406 is sleeved on the inner side of the fixing slot 405. When the plug block 404 is inserted into the slot 403, the second sealing rubber ring 406 is compressed, thereby forming a sealing barrier between the second upper flange 401 and the second lower flange 402, which can effectively prevent gas or liquid from leaking at the connection, thereby ensuring the closed environment of the tower body 1 and the stability of the fractionation process.

[0039] In one embodiment, the inner wall of the tower top 2 is provided with a tower plate 12, which is composed of an overflow weir, a downcomer, a liquid receiving tank and a sieve plate, which work together to achieve uniform distribution of liquid and sufficient contact of steam, thereby improving the fractionation effect.

[0040] In one embodiment, there are several trays 12 equidistantly distributed in the inner cavity of the tower top 2 , which can better improve the flow diversion effect.

[0041] In one embodiment, a liquid inlet 13 is provided at the bottom of one side of the tower top 2, and a gas outlet 14 is provided at the top of the other side of the tower top 2. The liquid inlet 13 is used to introduce the liquid to be fractionated into the tower body 1, and the gas outlet 14 is used to discharge the gas generated after the fractionation.

[0042] Working principle:

[0043] When in use, firstly, the tower body 1 structure includes a tower top 2 and a tower bottom 3, which are firmly connected by a first connecting mechanism 4, and the second upper flange 401 and the second lower flange 402 in the first connecting mechanism 4 are tightly matched. The design of the card slot 403 and the plug block 404 ensures precise docking in the vertical direction and prevents relative sliding by friction. At the same time, the second sealing rubber ring 406 forms a sealing barrier between the second upper flange 401 and the second lower flange 402 to prevent gas or liquid from leaking at the connection. Secondly, a steam inlet 6 and a second connecting mechanism 5 are provided at the bottom of the tower bottom 3. The first flange 501 and the card block 502 in the second connecting mechanism 5 make it simple and quick to connect the equipment with different steam sources, and the first sealing rubber ring 504 enhances the sealing of the connection, and the steam Steam enters the tower bottom 3 through the steam inlet 6, is dispersed through the partition 7 and evenly enters the tower body 1 through the air holes 8, ensuring the uniformity and efficiency of the distillation process. Inside the tower top 2, a plurality of tower plates 12 are arranged, which are composed of an overflow weir, a downcomer, a liquid receiving tank and a sieve plate. These components work together to achieve uniform distribution of liquid and sufficient contact of steam, thereby improving the distillation effect. During the distillation process, the liquid to be distilled enters the tower body 1 through the feed liquid inlet 13. After the separation effect of the tower plate 12, the liquids of different components are gradually separated in the tower, the lighter components rise and are discharged through the gas outlet 14, and the heavier components are discharged through the kettle liquid outlet 9. During the whole process, the structure of the tower plate 12 can optimize the distribution and flow of the liquid, improve the distillation efficiency and product quality.

[0044] In summary, the improved high-efficiency distillation tower, through the setting of the second connecting mechanism, enables the distillation tower to be flexibly connected to different steam sources and is no longer restricted by specific equipment or conditions. The simple structure of the first flange and the card block makes the connection process quick and simple, and the addition of the first sealing rubber ring greatly enhances the sealing of the connection, effectively prevents the leakage of steam or liquid, and ensures the safety and efficiency of the distillation process; secondly, the second upper flange cooperates with the second lower flange to form a stable connection structure, ensuring that the top and bottom of the tower can be tightly connected to prevent loosening or dislocation caused by vibration or external force. When the plug is inserted into the card slot, the second sealing rubber ring is compressed, thereby forming a sealing barrier between the second upper flange and the second lower flange, which can effectively prevent gas or liquid from leaking at the connection, ensuring the closed environment inside the tower body and the stability of the distillation process.

[0045] The improved high-efficiency distillation tower of the present application includes a tower body, which includes a tower top and a tower bottom. The tower top and the tower bottom are connected by a first connecting mechanism, and a second connecting mechanism is arranged at the bottom of the tower bottom; the second connecting mechanism includes a first flange, a clamping block, a mounting groove and a first sealing rubber ring. The first flange is fixedly installed at the middle position of the bottom of the tower bottom, the clamping block is fixedly installed at the bottom of the first flange, the mounting groove is opened on the outside of the clamping block, and the first sealing rubber ring is sleeved on the inside of the mounting groove, so that the distillation tower can be flexibly connected to different steam sources, and disassembly is convenient, and the sealing of the connection can be enhanced, effectively preventing the leakage of steam or liquid.
