Description

Technical Field

[0001] The present invention relates to the technical field of separation, and more specifically, it relates to a distillation column cooling device. Background Art

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

[0003] After the steam is discharged from the top of the distillation column, it enters the cooling device. The coolant is sprayed down from above, directly contacts the steam and conducts heat exchange. The steam is cooled and condensed into a liquid, and then discharged together with the coolant after mixing; the conventional spraying system has problems such as uneven droplet distribution and coverage blind spots, and it is difficult to form a continuous and uniform liquid curtain. Some steam escapes from the system without being fully condensed, and due to the impact of the coolant sprayed from above, the steam is prone to laminar flow accumulation at the bottom, and the flow velocity fluctuates within a large range. 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 discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and the functions and arrangements of the elements discussed can be changed without departing from the protection scope of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0042] Please refer to 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 coolant circulation component 300, a radial flow disturbing component 400, a coolant dispersion component 500, and a steam trapping component 600; the bottom of the tank body 200 is connected to the top of the distillation tower 100 through a steam pipe 210; the coolant circulation component 300 is arranged on one side of the tank body 200 and is used to circulate and transport the coolant at the bottom inside the tank body 200 to the top inside the tank body 200; the radial flow disturbing component 400 is arranged inside the tank body 200 and is used to radially disturb the steam rising from the bottom inside the tank body 200; the coolant dispersion component 500 is arranged at the top inside the tank body 200 and is connected to the output end of the coolant circulation component 300, and is used to circumferentially disperse the coolant output by the coolant circulation component 300 to the outside; the steam trapping component 600 is arranged inside the tank body 200 and is located below the radial flow disturbing component 400, and is used to periodically trap the steam input by the steam pipe 210;

[0043] Specifically, the steam in the distillation column 100 enters the tank body 200 through the steam pipe 210. The coolant circulation component 300 extracts the coolant at the bottom of the tank body 200 and transports it to the coolant dispersion component 500 at the top of the tank body 200. The coolant dispersion component 500 disperses the coolant circumferentially outward, so that the dispersed coolant covers the upper area inside the tank body 200. During the upward movement of the steam, it contacts the dispersed and covered coolant steam and undergoes heat exchange. The steam is cooled and condensed into a liquid, and then falls to the bottom of the tank body 200 after mixing with the coolant, thereby realizing the recovery and separation of the steam in the distillation column 100;

[0044] During the upward movement of the steam, the radial flow disturbing component 400 performs radial flow disturbance on the steam, so that the steam in the central area of the tank body 200 is evenly diverted radially outward, enabling the steam to more evenly contact and exchange heat with the coolant covered above, improving the heat exchange area and heat exchange efficiency; The steam trapping component 600 arranged at the bottom of the tank body 200 can periodically trap the steam discharged from the steam pipe 210, and then periodically push the trapped steam upward, prompting the steam to flow 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 in the present invention, the coolant circulation component 300 circulates and transports the coolant at the bottom of the tank body 200 to the coolant dispersion component 500 at the top of the tank body 200. The coolant dispersion component 500 disperses the coolant circumferentially to the outside to form a coolant curtain covering the upper area inside the tank body 200, enabling the rising steam to fully contact the coolant and realizing efficient heat exchange. The steam is cooled and condensed into a liquid, and then falls to the bottom of the tank body 200 after mixing with the coolant, thereby realizing the efficient cooling, separation and recovery of the steam;

[0046] The radial flow disturbing component 400 performs radial flow disturbance on the steam rising from the bottom inside the tank body 200, so that the steam in the central area of the tank body 200 is evenly diverted radially outward, avoiding the excessive concentration of the 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, and further improving the heat exchange area and heat exchange efficiency; Through the action of the radial flow disturbing component 400, the flow path of the steam is optimized, the resistance during the steam flow is reduced, and the distribution uniformity of the steam is improved;

[0047] The steam trapping component 600 can periodically trap the steam input by the steam pipe 210 and periodically push the trapped steam upward, prompting the steam to flow upward more efficiently, avoiding the accumulation of the steam at the bottom of the tank body 200, 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, please refer to Figure 2, the tank body 200 includes an outer shell 220 and an inner tank 230 disposed inside the outer shell 220. A liquid storage cavity 240 is formed between the inner tank 230 and the outer shell 220; an inlet pipe 250 and an outlet pipe 290 are respectively disposed at the bottom of the liquid storage cavity 240; the input end of the coolant circulation member 300 is communicated with the liquid storage cavity 240;

[0049] Specifically, external coolant is introduced into the liquid storage cavity 240 through the inlet pipe 250, and then the coolant in the liquid storage cavity 240 is transported to the coolant dispersion member 500 through the coolant circulation member 300. Subsequently, the coolant dispersed circumferentially by the coolant dispersion member 500 falls after contacting the steam, and then flows back to the liquid storage cavity 240 through the inner tank 230. The coolant that exchanges heat and recovers the steam is discharged from the liquid storage cavity 240 through the outlet pipe 290 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 the steam, when a certain amount of coolant is stored in the liquid storage cavity 240, the inlet pipe 250 and the outlet pipe 290 can be closed, so as to realize the internal circulation use of the coolant in the tank body 200 by using the coolant circulation member 300 to improve the utilization efficiency of the coolant; when a certain amount of steam is recovered in the coolant in the liquid storage cavity 240 or the temperature of the coolant reaches a certain threshold, the inlet pipe 250 and the outlet pipe 290 can be opened to discharge the stored coolant from the outlet pipe 290, and at the same time, new coolant is injected into the liquid storage cavity 240 through the 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 setting the liquid storage cavity 240 and the inlet pipe 250 and the 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 cavity 240, the inlet pipe 250 and the outlet pipe 290 are closed, and the internal circulation is realized by using the coolant circulation member 300 to improve the utilization efficiency of the coolant; when the coolant temperature or the recovered steam amount reaches a certain threshold, the inlet pipe 250 and the outlet pipe 290 are opened to realize the external circulation, discharge the high-temperature coolant and inject new coolant, so as to improve the heat exchange effect and the steam recovery effect; the circulation mode of the coolant can be adjusted according to the actual working conditions to ensure that the cooling device is always in the best operating state.

[0052] Further, please refer to Figure 2 , the coolant circulation member 300 includes a circulation pump 310 installed outside the outer shell 220. One end of the circulation pump 310 is communicated with the liquid storage cavity 240 through an input pipe 320, and the other end of the circulation pump 310 is communicated with 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 drive the turntable 510 and the conical dispersion table 530 to rotate synchronously; the circulation pump 310 pumps the extracted coolant into the annular pipe 520 through the output pipe 330, and then the coolant in the annular pipe 520 is sprayed out through each branch pipe 521 into each dispersion cavity 512 of the turntable 510. Subsequently, the coolant in the dispersion cavity 512 flows into the lower conical dispersion table 530 through the drain holes 513, and the circumferentially rotating conical dispersion table 530 evenly throws the received coolant outward, thereby forming a coolant curtain covering the upper opening of the inner tank 230 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] Further, please refer to Figure 4 , Figure 5 and Figure 8 , the steam trapping member 600 includes a connection disk 620 that is liftably arranged in the inner tank 230. A first flexible sheet 610 is arranged outside the connection disk 620, and the first flexible sheet 610 is fixedly connected to the inner wall of the inner tank 230 through a plurality of elastic bands arranged circumferentially. A second flexible sheet 630 is arranged inside the connection disk 620, and a through hole 640 is opened at the center of the second flexible sheet 630;

[0060] Specifically, when the connection disk 620 moves downward, it drives the second flexible sheet 630 to move downward synchronously and pass through the steam pipe 210, so that the upper opening of the steam pipe 210 passes through the through hole 640 and reaches above the second flexible sheet 630. At the same time, the first flexible sheet 610 depresses downward to trap the steam discharged from the steam pipe 210;

[0061] Subsequently, the connection disk 620 moves upward, driving the first flexible sheet 610 and the second flexible sheet 630 to move upward to push the trapped steam upward, thereby accelerating the steam flow and enabling the steam to quickly contact the coolant curtain above for cooling and recovery.

[0062] It should be noted that the steam trapping member 600 realizes the periodic trapping and pushing of steam through the lifting movement of the connection disk 620; when the connection disk 620 moves downward, the first flexible sheet 610 depresses downward to form a trapping space to trap the steam discharged from the steam pipe 210; subsequently, the connection disk 620 moves upward to push the trapped steam upward to accelerate the steam flow; this periodic trapping and pushing mechanism enables the steam to quickly contact the coolant curtain above for cooling and recovery, effectively improving the separation and recovery efficiency of the steam.

[0063] Please refer to Figure 5 and Figure 8, considering 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. Therefore, a spherical shell 260 is provided at the upper end of the steam pipe 210, and a plurality of steam outlets 261 are circumferentially formed at the bottom of the spherical shell 260;

[0064] In this way, since the steam outlets 261 are provided at the bottom of the spherical shell 260, the spherical part at the upper end of the spherical shell 260 can block the splashing coolant during the falling process, thereby effectively preventing the coolant from entering the steam pipe 210 through the steam outlets 261 at the bottom;

[0065] In addition, due to the spherical structure of the spherical shell 260, when the connecting disc 620 moves up and down, the second flexible sheet 630 can undergo adaptive telescopic deformation when passing through the spherical shell 260, so that the whole spherical shell 260 can smoothly pass through the through hole 640 to ensure the smooth progress of steam capture.

[0066] It should be noted that the spherical shell 260 provided at the upper end of the steam pipe 210, and the steam outlets 261 at its bottom can effectively prevent the coolant from entering the steam pipe 210 from the bottom; the spherical structure of the spherical shell 260 can undergo adaptive telescopic deformation during the up and down movement of the connecting disc 620 to ensure the smooth progress of steam capture.

[0067] Furthermore, please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 , for the up and down movement of the connecting disc 620, a reciprocating driving member 700 is further included. The reciprocating driving member 700 includes a plurality of groups of guide rods 710 vertically fixed on the inner wall of the inner tank 230 and an installation ring 720 fixedly connected to the connecting disc 620 through a connecting frame 650. A sliding frame 730 slidably adapted to the corresponding guide rod 710 is fixed on the installation ring 720; a sliding pin 740 is provided inside the installation ring 720, and a closed-loop spiral groove 421 adapted to the sliding pin 740 is formed on the rotating shaft 420;

[0068] Specifically, when the rotating shaft 420 rotates, through the transmission of the closed-loop spiral groove 421 and the sliding pin 740, the installation ring 720 and the sliding frame 730 are driven to slide up and down relative to the guide rod 710, and then the connecting disc 620 is driven to reciprocate up and down, so as to realize the periodic capture and upward pushing out of the steam.

[0069] In addition, please refer to Figure 4 , a plurality of drain grooves 270 are circumferentially formed at the bottom of the inner tank 230, and a plurality of sealing plates 280 are rotatably installed above the drain 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.
