Description

Technical Field

[0001] The invention relates to the technical field of isohexanediol preparation, in particular to a distillation device for isohexanediol preparation. Background Art

[0002] Isohexanediol, also known as 2-methyl-2,4-pentanediol, is a chemical substance that can be used in the fields of pesticides, biochemical engineering, photosensitive materials, synthetic fragrances, etc. Due to its low flammability, low evaporation rate, and low surface tension, isohexanediol is widely used in paints, coatings, textiles, organophosphorus pesticide stabilizers, hydraulic oils, metalworking fluids, drilling fluids, and other fields. With the continuous improvement of environmental awareness and the continuous development of chemical technology, isohexanediol, as an important chemical raw material and environmentally friendly plasticizer, has a growing market demand. Therefore, distillation equipment for the preparation of isohexanediol has broad application prospects in the chemical industry.

[0003] The preparation and distillation process of isohexanediol is generally carried out in a distillation tower, which is a gas-liquid contact device that can separate the mixture according to the different volatilities of the components. The distillation tower can be divided into a plate tower and a packed tower according to the basic method of gas-liquid two-phase. The plate tower consists of a usually cylindrical shell and a number of plates arranged horizontally at a certain interval. When the plate tower is working normally, the isohexanediol liquid passes through each layer of the plates from top to bottom under the action of gravity and is discharged from the bottom of the tower. The gas is driven by the pressure difference and passes through each layer of the plates from bottom to top through the openings evenly distributed on the plates and is discharged from the top of the tower. A certain amount of liquid is stored on each plate. When the gas passes through the liquid layer on the plate, the two phases contact for mass transfer.

[0004] However, the steam flowing from bottom to top inside the distillation tower body needs to be transmitted upward from the sieve holes on the tower plate during the circulation process, while the isohexanediol liquid on the tower plate will flow downward from the sieve holes. This hinders the upward flow speed of the steam to a certain extent, resulting in the distillation efficiency of isohexanediol being affected, making it difficult to meet the demand.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] See also Figure 1-7 The present invention provides a distillation device for preparing isohexanediol, comprising a distillation tower body 1, a steam pipe 8, a liquid pipe 9, and a support 10. A driving motor 2 is fixedly installed at the bottom of the distillation tower body 1, and a tower plate 3 is arranged inside the distillation tower body 1. An annular groove 4 is opened on the inner wall of the distillation tower body 1 corresponding to the tower plate 3.

[0031] A steam boosting component 5 is arranged inside the distillation tower body 1 .

[0032] Furthermore, the steam booster component 5 includes a driving rod 501, an output shaft at one end of the driving motor 2 passes through the interior of the distillation tower body 1 and is fixedly connected to the bottom of the driving rod 501, and a sleeve 502 is provided on the outer wall of the driving rod 501, an inner groove 503 is provided through the top of the sleeve 502, and the inner wall of the inner groove 503 is slidably fitted with the outer wall of the driving rod 501, and a ball 504 is fixedly connected to the inner wall of the sleeve 502, and the outer wall of the driving rod 501 corresponds to the ball 504. 04 is provided with a spiral groove 505, and the outer wall of the ball 504 fits and slides with the inner wall of the spiral groove 505, the outer wall of the sleeve 502 is fixedly connected with a push plate 506, and the outer wall of the push plate 506 fits and slides with the inner wall of the distillation tower body 1, the outer wall of the push plate 506 is symmetrically fixedly connected with a limiting block 507, the inner wall of the distillation tower body 1 corresponds to the limiting block 507 symmetrically provided with a limiting groove 7, and the outer wall of the limiting block 507 fits and slides with the inner wall of the limiting groove 7.

[0033] In this embodiment, when preparing distillation of isohexanediol, steam is first transported into the distillation tower body 1 through the steam pipe 8, so that the steam naturally flows from the bottom to the top of the distillation tower body 1, and then the isohexanediol liquid is sent into the distillation tower body 1 through the liquid pipe 9 and falls on the upper surface of the tower plate 3, so that when the steam passes through the liquid layer on the tower plate 3, the two phases contact and carry out mass transfer.

[0034] Then, the driving motor 2 is started, and the output shaft at one end of the driving motor 2 passes through the interior of the distillation tower body 1 and is fixedly connected to the bottom of the driving rod 501, so that the driving motor 2 can drive the driving rod 501 to rotate, and then a sleeve 502 is provided on the outer wall of the driving rod 501, and an inner groove 503 is provided through the top of the sleeve 502, and the inner wall of the inner groove 503 fits and slides with the outer wall of the driving rod 501, and at the same time, a ball 504 is fixedly connected to the inner wall of the sleeve 502, and a spiral groove 505 is provided on the outer wall of the driving rod 501 corresponding to the ball 504, and the outer wall of the ball 504 fits and slides with the inner wall of the spiral groove 505, and at the same time, a pushing plate 506 is fixedly connected to the outer wall of the sleeve 502, and the outer wall of the pushing plate 506 fits and slides with the distillation tower body 1. The inner walls of the distillation tower body 1 fit and slide together, and the outer wall of the push plate 506 is symmetrically fixedly connected to the limiting block 507. At the same time, the inner wall of the distillation tower body 1 corresponds to the limiting block 507 and symmetrically opens the limiting groove 7, and the outer wall of the limiting block 507 fits and slides with the inner wall of the limiting groove 7, so that the movement of the push plate 506 is restricted under the cooperation of the limiting block 507 and the limiting groove 7, so that it can only slide up and down and cannot rotate, so as to limit the ball 504 in the sleeve 502, so that when the driving rod 501 rotates, it can drive the push plate 506 to rise rapidly through the cooperation of the spiral groove 505 and the ball 504, so that the push plate 506 can push the steam located at the lower part of the distillation tower body 1 upward, thereby ensuring the upward circulation speed of the steam.

[0035] Then, in order to enable the circulation and avoid the push disk 506 from directly moving downward to squeeze the steam in the distillation tower body 1, the upper surface of the blocking disk 508 is fitted with the lower surface of the pushing disk 506, and the outer wall of one side of the blocking disk 508 is fixedly connected with a cylinder 510, and the end of the cylinder 510 away from the driving rod 501 is provided with a groove, and the inner wall of the groove is fixedly connected with a spring 511, and the other end of the spring 511 is fixedly connected with a sliding column 512, and the inner wall of one side of the distillation tower body 1 is provided with a conversion groove 513 corresponding to the sliding column 512, and the inner wall of the conversion groove 513 is fixedly connected with a partition plate 514, and The two side walls of the partition plate 514 are fixedly connected with lifting blocks 515, and the lifting blocks 515 are inclined on the side facing the sliding column 512. At the same time, the two ends of the partition plate 514 are fixedly connected with conversion blocks 516, and the side wall of the conversion blocks 516 facing the sliding column 512 is inclined, and through holes 517 are evenly spaced through the insides of the push plate 506 and the blocking plate 508. Therefore, when they are not pushed, the through holes 517 between the blocking plate 508 and the push plate 506 are not aligned, so that steam cannot pass between the push plate 506 and the blocking plate 508, so that the push plate 506 can push the steam when it rises.

[0036] Then, when the push plate 506 rises, the slide post 512 will be driven to move synchronously. At this time, one end of the slide post 512 is against the inclined surface of one of the lifting blocks 515 driven by the spring 1 511, and as the push plate 506 rises, the slide post 512 is gradually retracted into the groove under the guidance of the inclined surface. When the push plate 506 rises to the highest point, the slide post 512 will slide from the inclined surface of one of the lifting blocks 515 into the surface of the conversion block 516 located at the upper part of the conversion groove 513, and is located at the highest point of the inclined surface of the conversion block 516, and at this time the slide post 512 is no longer affected by the division The partition 514 is blocked. At this time, under the elastic force of spring 1 511, the sliding column 512 will slide from the highest point of the inclined surface of the conversion block 516 to the lowest point driven by the elastic force of spring 1 511. At this time, the rotation of the sealing disk 508 is completed. At this time, the through holes 517 between the pushing disk 506 and the sealing disk 508 will correspond one to one. At this time, when the pushing disk 506 moves downward, the steam will be able to pass normally between the pushing disk 506 and the sealing disk 508, thereby avoiding squeezing the steam, resulting in an increase in the pressure drop in the tower, reducing the need for additional power due to the increase in pressure drop, and thus reducing energy consumption.

[0037] Then, at this time, the slide column 512 will move and shrink on the inclined surface of another lifting block 515, and when the pushing plate 506 drops to the lowest point, the slide column 512 will slide from the highest point of the lifting block 515 to the surface of the conversion block 516 located at the lower part of the conversion groove 513, and is located at the highest point of the inclined surface of the conversion block 516. At this time, the slide column 512 is no longer blocked by the partition plate 514. At this time, under the elastic force of spring 1 511, the slide column 512 will slide from the highest point of the inclined surface of the conversion block 516 to the lowest point under the elastic force of spring 1 511. At this time, the resetting of the blocking plate 508 is completed, and the pushing plate 506 is re-blocked, thereby realizing the cyclic step of steam pushing.

[0038] As described above, when isohexanediol is distilled, the drive motor 2 can be used to drive the drive rod 501 to rotate, so that with the cooperation of the spiral groove 505 and the ball 504, the push plate 506 can push the steam located at the lower part of the distillation tower body 1 upward, thereby ensuring the upward circulation speed of the steam, which is beneficial to improving the distillation efficiency of isohexanediol of the present equipment. At the same time, through the cooperation of the lifting block 515 and the conversion block 516, the push plate 506 is in an open state when it descends, avoiding squeezing the steam, resulting in an increase in the pressure drop in the tower, reducing the additional power required due to the increase in the pressure drop, thereby reducing energy consumption and improving the reliability of the entire distillation system.

[0039] Embodiment 2

[0040] On the basis of the above-mentioned embodiment 1, a vibration mixing component 6 is provided on the inner wall of the annular groove 4 .

[0041] Furthermore, the vibration mixing component 6 includes a sliding rod 601, and the two ends of the sliding rod 601 are fixedly connected to the inner wall of the annular groove 4, and a sliding groove 602 is symmetrically opened inside the tower plate 3 corresponding to the sliding rod 601, and the inner wall of the sliding groove 602 slides in contact with the outer wall of the sliding rod 601, and a spring 2 603 is equidistantly provided on the outer wall of the sliding rod 601, and one end of the spring 2 603 is fixedly connected to the outer wall of the tower plate 3, and the other end of the spring 2 603 is fixedly connected to the inner wall of the annular groove 4.

[0042] In this embodiment, when distilling isohexanediol, first, the two ends of the slide bar 601 are fixedly connected to the inner wall of the annular groove 4, and the inner part of the tower plate 3 is symmetrically penetrated by the corresponding slide bar 601, and the inner wall of the slide groove 602 is fitted and slid with the outer wall of the slide bar 601, and the outer wall of the slide bar 601 is equidistantly fitted with springs 603, and one end of the spring 603 is fixedly connected to the outer wall of the tower plate 3, and the other end of the spring 603 is fixedly connected to the inner wall of the annular groove 4, so that the tower plate 3 can be supported by the two springs 603 located on the upper and lower surfaces of the tower plate 3, so that the tower plate 3 is located in the middle of the slide bar 601;

[0043] When the driving rod 501 rotates, a fixed disk 604 is fixedly connected through the inner center of the tower plate 3 through the top of the driving rod 501, and a protrusion 1 605 is fixedly connected to the bottom of the fixed disk 604 at an equal distance, and a protrusion 2 606 is fixedly connected to the upper surface of the tower plate 3 at an equal distance corresponding to the protrusion 1 605, and at the same time, the outer walls of both sides of the protrusion 1 605 and the protrusion 2 606 are both inclined, so that the driving rod 501 can drive the fixed disk 604 to rotate, so that the fixed disk 604 can contact and collide with the multiple protrusions 1 605 on the multiple protrusions 2 606, and under the guidance of the inclined surface, the tower plate 3 will be squeezed downward for a certain distance, and can be returned to the original position by using the two springs 2 603, so that the tower plate 3 can be continuously vibrated, which is conducive to breaking the static state of the liquid on the tower plate 3, promoting the mixing and renewal of the liquid, reducing the retention time of the liquid on the tower plate 3, and avoiding the occurrence of local overheating or blockage;

[0044] As described above, when isohexanediol is distilled, the rotation of the driving rod 501 can drive the plurality of protrusions 605 to move in a circle, so that the cooperation between the spring 2 603 and the slide bar 601 can enable the tower plate 3 to vibrate continuously, which is beneficial to breaking the static state of the liquid on the tower plate 3, promoting the mixing and renewal of the liquid, reducing the residence time of the liquid on the tower plate 3, avoiding the occurrence of local overheating or blockage, and helping to maintain smooth flow of the liquid on the tower plate 3, thereby improving the distillation efficiency of the device.

[0045] Working principle: When preparing distillation of isohexanediol, firstly, steam is transported into the distillation tower body 1 through the steam pipe 8, so that the steam naturally flows from the bottom to the top of the distillation tower body 1, and then the isohexanediol liquid is transported into the distillation tower body 1 through the liquid pipe 9 and falls on the upper surface of the tower plate 3, so that when the steam passes through the liquid layer on the tower plate 3, the two phases contact and transfer mass;

[0046] Then, the movement of the push plate 506 is restricted under the cooperation of the limit block 507 and the limit groove 7, so that it can only slide up and down but cannot rotate, so as to restrict the ball 504 in the sleeve 502, so that when the driving rod 501 rotates, the push plate 506 can be driven to rise quickly through the cooperation of the spiral groove 505 and the ball 504, so that the push plate 506 can push the steam located at the lower part of the distillation tower body 1 upward, thereby ensuring the upward circulation speed of the steam;

[0047] Then, in the non-pushing state, the through holes 517 between the blocking plate 508 and the pushing plate 506 are not aligned, so that the steam cannot pass between the pushing plate 506 and the blocking plate 508, so that the pushing plate 506 can push the steam when it rises. When the pushing plate 506 rises, it will synchronously drive the sliding column 512 to move. At this time, one end of the sliding column 512 is against the inclined surface of one of the lifting blocks 515 driven by the spring 1 511, and as the pushing plate 506 rises, the sliding column 512 is gradually retracted into the groove under the guidance of the inclined surface;

[0048] When the push plate 506 rises to the highest point, the slide post 512 will slide from the inclined surface of one of the lifting blocks 515 into the surface of the conversion block 516 located at the upper part of the conversion groove 513, and is located at the highest point of the inclined surface of the conversion block 516, and the slide post 512 is no longer blocked by the partition plate 514. At this time, under the elastic force of the spring 1 511, the slide post 512 will slide from the highest point of the inclined surface of the conversion block 516 to the lowest point driven by the elastic force of the spring 1 511, and the rotation of the blocking plate 508 is completed. At this time, the through holes 517 between the push plate 506 and the blocking plate 508 will correspond to each other one by one. At this time, when the push plate 506 moves downward, the steam can pass normally between the push plate 506 and the blocking plate 508, thereby avoiding squeezing of the steam;

[0049] Then, when the driving rod 501 rotates, the fixed plate 604 is driven to rotate through the driving rod 501, so that the fixed plate 604 can contact and collide with the multiple protrusions 606 through the multiple protrusions 1 605, and under the guidance of the inclined surface, the tower plate 3 will be squeezed downward for a certain distance, and can return to its original position by using the two springs 2 603, so that the tower plate 3 can vibrate continuously, which is beneficial to break the static state of the liquid on the tower plate 3, promote the mixing and renewal of the liquid, reduce the residence time of the liquid on the tower plate 3, and avoid the occurrence of local overheating or blockage.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
