Description

Technical Field

[0001] The present invention relates to the field of separation technology, and more particularly to a distillation tower cooling device. Background Art

[0002] A distillation tower is a chemical equipment used to separate liquid mixtures. During the distillation process, the mixture is heated to boiling, and the components with lower boiling points are first converted into steam and rise. The direct contact cooling device is the core equipment for condensation and recovery of distillation tower steam. Its separation efficiency directly affects the energy utilization rate and product recovery rate.

[0003] After being discharged from the top of the distillation tower, the steam enters the cooling device, and the coolant sprays down from above, directly contacts with the steam and performs heat exchange. The steam is cooled and condensed into liquid, which is discharged together with the coolant. Conventional spray systems have problems such as uneven droplet distribution and blind coverage areas, making it difficult to form a continuous and uniform liquid curtain. Part of the steam escapes the system without being fully condensed, and is impacted by the coolant sprayed above, causing laminar accumulation of the steam at the bottom, and a large fluctuation range of the flow velocity. This instability causes a significant difference in the contact time between the steam and the coolant, affecting the steam separation efficiency. Summary of the invention

[0041] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0042] See also Figure 1 , Figure 2 and Figure 3 The present invention discloses a distillation tower cooling device, which is applied to a distillation tower 100, and includes a tank body 200, a cooling liquid circulation member 300, a radial spoiler 400, a cooling liquid dispersion member 500 and a steam capture member 600; the bottom of the tank body 200 is connected to the top of the distillation tower 100 through a steam pipe 210; the cooling liquid circulation member 300 is arranged on one side of the tank body 200, and is used to circulate and transport the cooling liquid at the bottom of the tank body 200 to the top of the tank body 200; the radial spoiler 400 is arranged in the tank body 200, and is used to radially turbulent the steam rising from the bottom of the tank body 200; the cooling liquid dispersion member 500 is arranged at the top of the tank body 200 and is connected to the output end of the cooling liquid circulation member 300, and is used to circumferentially disperse the cooling liquid output by the cooling liquid circulation member 300 to the outside; the steam capture member 600 is arranged in the tank body 200 and is located below the radial spoiler 400, and is used to periodically capture the steam input by the steam pipe 210;

[0043] Specifically, the steam in the distillation tower 100 enters the tank body 200 through the steam pipe 210, and the coolant at the bottom of the tank body 200 is extracted by the coolant circulation part 300 and transported to the coolant dispersion part 500 at the top of the tank body 200. The coolant dispersion part 500 disperses the coolant circumferentially outward, so that the dispersed coolant covers the upper area inside the tank body 200. During the rising process of the steam, it contacts the dispersed and covered coolant steam and performs heat exchange. After being cooled, the steam is condensed into liquid, mixed with the coolant and falls to the bottom of the tank body 200 together, thereby realizing the recovery and separation of the steam in the distillation tower 100;

[0044] During the rising process of steam, the radial spoiler 400 is used to radially spoil the steam, so that the steam in the central area of ​​the tank body 200 is evenly diverted radially outward, so that the steam can more evenly contact and exchange heat with the coolant covering it, thereby increasing the heat exchange area and heat exchange efficiency; the steam capture member 600 arranged at the bottom of the tank body 200 can periodically capture the steam discharged from the steam pipe 210, and then periodically push the captured steam upward, so as to promote the steam to circulate upward more efficiently, so as to improve the fluidity of the steam in the tank body 200, thereby further improving the separation effect.

[0045] It should be noted that the coolant circulation member 300 in the present invention circulates the coolant at the bottom of the tank body 200 to the coolant dispersing member 500 at the top of the tank body 200, and the coolant dispersing member 500 disperses the coolant circumferentially to the outside to form a coolant curtain covering the upper area inside the tank body 200, so that the rising steam can fully contact the coolant to achieve efficient heat exchange. The steam is cooled and condensed into liquid, and then mixed with the coolant and falls to the bottom of the tank body 200, thereby achieving efficient cooling and separation and recovery of the steam;

[0046] The radial spoiler 400 radially spoils the steam rising from the bottom of the tank body 200, so that the steam in the central area of ​​the tank body 200 is evenly diverted radially outward, avoiding excessive concentration of steam in the central area of ​​the tank body 200, ensuring that the steam can more evenly contact and exchange heat with the coolant covered above, further improving the heat exchange area and heat exchange efficiency; through the action of the radial spoiler 400, the flow path of the steam is optimized, the resistance in the steam flow process is reduced, and the uniformity of steam distribution is improved;

[0047] The steam trap 600 can periodically capture the steam input from the steam pipe 210 and periodically push the captured steam upward, thereby promoting the steam to flow upward more efficiently, avoiding the accumulation of steam at the bottom of the tank body 200, and further improving the fluidity of the steam in the tank body 200, thereby improving the heat exchange effect and the utilization efficiency of the steam.

[0048] In one embodiment, see Figure 2The tank body 200 includes an outer shell 220 and an inner liner 230 disposed in the outer shell 220, and a liquid storage chamber 240 is formed between the inner liner 230 and the outer shell 220; a liquid inlet pipe 250 and a liquid outlet pipe 290 are respectively disposed at the bottom of the liquid storage chamber 240; the input end of the coolant circulation member 300 is connected to the liquid storage chamber 240;

[0049] Specifically, the external coolant is introduced into the liquid storage chamber 240 through the liquid inlet pipe 250, and then the coolant in the liquid storage chamber 240 is transported to the coolant dispersing member 500 through the coolant circulation member 300. Then, the coolant dispersed circumferentially through the coolant dispersing member 500 contacts the steam and falls down, and flows back to the liquid storage chamber 240 through the inner tank 230. The coolant that exchanges heat and recovers steam is discharged from the liquid storage chamber 240 through the liquid outlet pipe 290, so as to realize the circulation of the coolant and the separation and recovery of the steam.

[0050] It should be noted that, during the process of cooling and recovering steam, when a certain amount of coolant is stored in the liquid storage chamber 240, the liquid inlet pipe 250 and the liquid outlet pipe 290 can be closed, so that the coolant circulation member 300 can be used to realize the internal circulation of the coolant in the tank body 200 to improve the utilization efficiency of the coolant; when a certain amount of steam is recovered from the coolant in the liquid storage chamber 240 or the temperature of the coolant reaches a certain threshold, the liquid inlet pipe 250 and the liquid outlet pipe 290 can be opened to discharge the stored coolant from the liquid outlet pipe 290, and at the same time, new coolant can be injected into the liquid storage chamber 240 through the liquid inlet pipe 250 to realize the external circulation of the coolant and improve the heat exchange effect and the steam separation effect;

[0051] It is worth noting that by providing a liquid storage chamber 240 and a liquid inlet pipe 250 and a liquid outlet pipe 290, two modes of internal circulation and external circulation of the coolant are realized; when a certain amount of coolant is stored in the liquid storage chamber 240, the liquid inlet pipe 250 and the liquid outlet pipe 290 are closed, and the coolant circulation component 300 is used to realize internal circulation to improve the utilization efficiency of the coolant; when the coolant temperature or the amount of recovered steam reaches a certain threshold, the liquid inlet pipe 250 and the liquid outlet pipe 290 are opened to realize external circulation, discharge the high-temperature coolant and inject new coolant, thereby improving the heat exchange effect and the steam recovery effect; the coolant circulation mode can be adjusted according to the actual working conditions to ensure that the cooling device is always in the best operating state.

[0052] For further information, see Figure 2 The coolant circulation member 300 includes a circulation pump 310 installed outside the housing 220, one end of the circulation pump 310 is connected to the liquid storage chamber 240 through an input pipe 320, and the other end of the circulation pump 310 is connected to the coolant dispersion member 500 through an output pipe 330;

[0053] Specifically, when cooling and recovering steam, the circulation pump 310 is turned on, the coolant stored in the liquid storage chamber 240 is extracted through the input pipe 320, and the extracted coolant is output to the coolant dispersion member 500 through the output pipe 330 to realize the transportation of the coolant.

[0054] For further information, see Figure 3 The radial spoiler 400 includes a rotating shaft 420 rotatably mounted in the tank body 200, and one end of the rotating shaft 420 extending into the inner tank 230 is circumferentially provided with a plurality of spoiler plates 430, and the spoiler plates 430 are located below the coolant dispersion member 500, and a motor 410 for driving the rotating shaft 420 is installed on the top of the housing 220;

[0055] Specifically, when steam cooling is performed, the motor 410 drives the rotating shaft 420 to rotate, thereby driving each group of spoiler plates 430 to rotate circumferentially to achieve radial turbulence of the steam in the inner liner 230, so that the steam in the central area of ​​the inner liner 230 escapes radially outward to drive the steam to flow toward the cooling liquid curtain above, thereby improving the fluidity of the steam and making the steam more evenly dispersed to increase the contact area between the steam and the cooling liquid curtain.

[0056] It can be understood that the motor 410 drives the shaft 420 to rotate, driving the spoiler 430 to rotate circumferentially, thereby achieving radial turbulence of the steam in the inner liner 230, allowing the steam in the central area of ​​the inner liner 230 to escape radially outward, driving the steam to flow toward the cooling liquid curtain above, thereby improving the fluidity of the steam. The rotation of the spoiler 430 makes the steam more evenly dispersed, increases the contact area between the steam and the cooling liquid curtain, and thus improves the heat exchange efficiency.

[0057] In yet another embodiment, see Figure 4 , Figure 5 and Figure 6 The coolant dispersing member 500 includes a turntable 510 fixedly sleeved on the rotating shaft 420 and an annular tube 520 fixed in the housing 220. A plurality of partitions 511 are circumferentially arranged inside the turntable 510, and a dispersion chamber 512 is formed between adjacent partitions 511. A drainage hole 513 is provided at the bottom of the dispersion chamber 512. The outer side of the annular tube 520 is connected to the output pipe 330, and a plurality of branch pipes 521 adapted to the dispersion chamber 512 are circumferentially arranged inside the annular tube 520. A conical dispersing table 530 is integrally connected to the bottom of the turntable 510, and a plurality of flow partitions 531 are circumferentially arranged on the upper end surface of the conical dispersing table 530.

[0058] Specifically, while the rotating shaft 420 drives the spoiler 430 to rotate, it can also drive the turntable 510 and the conical dispersion table 530 to rotate synchronously; the circulating pump 310 pumps the extracted coolant into the annular tube 520 through the output pipe 330, and then the coolant in the annular tube 520 is sprayed into the dispersion chambers 512 of the turntable 510 through the branch pipes 521, and then the coolant in the dispersion chamber 512 flows into the conical dispersion table 530 below through the drainage hole 513, and the circumferentially rotating conical dispersion table 530 evenly throws the received coolant to the outside, thereby forming a coolant curtain covering the upper opening of the inner tank 230, so as to increase the contact area between the coolant and the steam, and at the same time prevent the steam from escaping upward and affecting the steam recovery rate.

[0059] For further information, see Figure 4 , Figure 5 and Figure 8 The steam trap 600 includes a connection plate 620 that is escalably disposed in the inner liner 230, a first flexible sheet 610 is disposed on the outer side of the connection plate 620, and the first flexible sheet 610 is fixedly connected to the inner wall of the inner liner 230 through a plurality of elastic bands disposed circumferentially, a second flexible sheet 630 is disposed on the inner side of the connection plate 620, and a through hole 640 is opened at the center of the second flexible sheet 630;

[0060] Specifically, when the connection plate 620 moves downward, the second flexible sheet 630 is driven to move downward synchronously and pass through the steam pipe 210, so that the upper end opening of the steam pipe 210 passes through the through hole 640 to reach the top of the second flexible sheet 630, and at the same time, the first flexible sheet 610 is recessed downward to capture the steam discharged from the steam pipe 210;

[0061] Then the connecting plate 620 moves upward, driving the first flexible sheet 610 and the second flexible sheet 630 to move upward, so as to push the captured steam upward, thereby accelerating the flow of steam, so that the steam can quickly contact the cooling liquid curtain above for cooling recovery.

[0062] It should be noted that the steam collecting member 600 realizes the periodic capture and promotion of steam through the lifting and lowering movement of the connecting plate 620; when the connecting plate 620 moves downward, the first flexible sheet 610 is recessed downward to form a capture space to capture the steam discharged from the steam pipe 210; then the connecting plate 620 moves upward to push the captured steam upward to accelerate the flow of steam; this periodic capture and promotion mechanism enables the steam to quickly contact the cooling liquid curtain above for cooling recovery, effectively improving the separation and recovery efficiency of the steam.

[0063] See also Figure 5 and Figure 8Considering that the coolant after heat exchange is prone to splashing during the falling process, which may easily cause the coolant to enter the steam pipe 210, a spherical shell 260 is provided at the upper end of the steam pipe 210, and a plurality of steam outlets 261 are opened in the circumferential direction at the bottom of the spherical shell 260;

[0064] In this way, since the steam outlet 261 is arranged at the bottom of the spherical shell 260, the spherical part at the upper end of the spherical shell 260 can shield the falling splashing coolant, thereby effectively preventing the coolant from entering the steam pipe 210 from the steam outlet 261 at the bottom;

[0065] In addition, due to the spherical structure of the spherical shell 260, when the connecting plate 620 is raised or lowered, the second flexible sheet 630 can undergo adaptive telescopic deformation when passing through the spherical shell 260, so that the spherical shell 260 as a whole can smoothly pass through the through hole 640 to ensure smooth steam capture.

[0066] It is worth noting that the spherical shell 260 arranged at the upper end of the steam pipe 210 and the steam outlet 261 at the bottom can effectively prevent the coolant from entering the steam pipe 210 from the bottom; the spherical structure of the spherical shell 260 can adaptively expand and contract during the lifting and lowering process of the connecting plate 620 to ensure smooth steam capture.

[0067] For further information, see Figure 3 , Figure 4 , Figure 5 and Figure 7 , for the lifting movement of the connecting plate 620, it also includes a reciprocating driving member 700, the reciprocating driving member 700 includes a plurality of guide rods 710 vertically fixed on the inner wall of the inner tank 230 and a mounting ring 720 fixedly connected to the connecting plate 620 through a connecting frame 650, and a sliding frame 730 slidably matched with the corresponding guide rod 710 is fixed on the mounting ring 720; a sliding pin 740 is arranged on the inner side of the mounting ring 720, and a closed-loop spiral groove 421 matched with the sliding pin 740 is opened on the rotating shaft 420;

[0068] Specifically, when the rotating shaft 420 rotates, the closed-loop spiral groove 421 and the sliding pin 740 are transmitted, thereby driving the mounting ring 720 and the sliding frame 730 to slide back and forth relative to the guide rod 710, thereby driving the connecting plate 620 to move up and down to achieve the periodic capture and upward push of steam.

[0069] Also, see Figure 4 A plurality of drainage grooves 270 are provided on the bottom of the inner tank 230 in a circumferential direction, and a plurality of sealing plates 280 are rotatably installed above the drainage grooves 270;

[0070] When the sealing plate 280 is opened, the drain groove 270 is connected, and the coolant falling from the top can flow back to the liquid storage chamber 240 through the drain groove 270, thereby realizing the circulation of the coolant; when the sealing plate 280 closes the drain groove 270, the falling coolant will be retained at the bottom of the inner tank 230, thereby preventing the coolant after heat exchange from flowing back to the liquid storage chamber 240 and causing mixing with the unused coolant, which can ensure the subsequent cooling effect of the unused coolant on the one hand, and ensure the consistency of the content of the steam condensation component in the coolant after heat exchange on the other hand;

[0071] The drain groove 270 and the sealing plate 280 can be opened or closed as needed to prevent the coolant after heat exchange from flowing back into the liquid storage chamber 240, avoid mixing of the coolant, and ensure the cooling effect of the unused coolant and the consistency of the content of the steam condensation component in the coolant after heat exchange.

[0072] The specific implementation modes of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present invention, those skilled in the art may also make many forms, all of which are within the protection of the present invention.
