Description

A component and method for preventing clogging in the bottom of a dimethyl carbonate deweighting tower. Technical Field

[0001] This invention belongs to the field of reaction tower technology, specifically a dimethyl carbonate deweighting tower reboiler anti-clogging component and anti-clogging method. Background Technology

[0002] The anti-clogging component of the dimethyl carbonate deweighting tower is an important piece of equipment used in the deweighting tower reboiler during the dimethyl carbonate production process. It prevents clogging within the reboiler, ensuring the smooth operation of the production process. Its main function is to prevent equipment blockage caused by deposits, scale, and impurities during production through the design and application of specific anti-clogging devices, thus guaranteeing the normal operation of the system.

[0003] A prior art document, CN213913682U, discloses a carbonation reactor for nano-calcium carbonate, comprising a reaction tower, a feeding mechanism, an air inlet mechanism, and a stirring mechanism. The reaction tower has a feed inlet and an air inlet at its top, and a discharge outlet and a circulating outlet at its bottom. The feeding mechanism includes a feed coil fixed inside the reactor and connected to the feed inlet, and a feed pump located outside the reactor and connected to the feed inlet. The feed coil has several nozzles at its bottom, and the feed pump is also connected to the circulating outlet. The air inlet mechanism includes an air inlet coil fixed inside the reactor, corresponding to the area below the feed coil, and connected to the air inlet.

[0004] While the aforementioned application can improve the equipment's reaction efficiency, during operation inside the reaction tower, the liquid and gas mix through multiple trays. Particulate matter generated during this mixing process can clog or even become stuck inside the tray's orifices. When these orifices are blocked, the flow of liquid and gas is hindered, reducing gas-liquid contact efficiency. This leads to uneven heat and mass transfer during the reaction, affecting the reaction rate and the quality of the final product. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dimethyl carbonate de-clogging tower reboiler anti-clogging component, comprising a reaction tower body, a support base fixedly connected to the bottom outer wall of the reaction tower body, a feed pipe connected to one side of the top inner wall of the reaction tower body, a gas injection pipe connected to one side of the bottom inner wall of the reaction tower body, a discharge pipe connected to the bottom of the reaction tower body, and exhaust pipes connected to both sides of the top of the reaction tower body; further comprising a separation anti-clogging mechanism, the separation anti-clogging mechanism comprising a motor fixedly connected to the center of the top of the reaction tower body, a rotating shaft fixedly connected to the output end of the motor, two cross sleeves fixedly connected to both ends of the outer wall of the rotating shaft, and a separation component provided on the outer wall of the cross sleeve for separating dimethyl carbonate from the material.

[0007] Preferably, the separation assembly includes a tray slidably connected to the outer wall of the bottom end of the cross sleeve, the top of the tray having multiple through holes, a square cylinder fixedly connected to one side of the outer wall of the tray, and one side of the outer wall of the square cylinder slidably connected to the inner wall of the reaction tower body.

[0008] Preferably, one end of the discharge pipe passes through and extends to the outside of the support base, an arc-shaped ring plate is fixedly connected to the top of the inner wall of the reaction tower body, a reflux pipe is connected to the inner wall of the reaction tower body near the top of the arc-shaped ring plate, and the bottom end of the reflux pipe is connected to the bottom end of the inner wall of the reaction tower body.

[0009] Preferably, the bottom end of the rotating shaft is provided with an anti-blocking component, the anti-blocking component including a reciprocating lead screw fixedly connected to the outer wall of the bottom end of the rotating shaft, and a lifting frame is threadedly connected to the outer wall of the bottom end of the reciprocating lead screw.

[0010] Preferably, two limiting plates are slidably connected to both sides of the outer wall of the lifting frame, one side of the limiting plate is fixedly connected to the inner wall of the reaction tower body, and an annular groove is provided on the top of the lifting frame.

[0011] Preferably, two sliders are slidably connected to both ends of the inner wall of the annular groove, a vertical rod is fixedly connected to the top of the slider, two fixing rings are fixedly connected to both ends of the outer wall of the vertical rod, multiple horizontal plates are fixedly connected to the outer wall of the fixing rings, and a sliding frame rod is slidably connected through the top of the horizontal plate.

[0012] Preferably, a compression plate is fixedly connected to the top of the sliding frame rod, a compression spring is fixedly connected to the bottom of the compression plate, and the bottom of the compression spring is fixedly connected to the top of the cross plate.

[0013] Preferably, the top of the horizontal plate is provided with an auxiliary component, which includes four tapered rods fixedly connected to the top of the horizontal plate, and the top of the extrusion plate is provided with four circular holes.

[0014] Preferably, two fixing frames are fixedly connected to both ends of the inner wall of the reaction tower body, and a circular cylinder is fixedly connected to the inner wall of the fixing frame. Multiple cleaning plates are fixedly connected to the outer wall of the bottom end of the circular cylinder.

[0015] A method for preventing clogging in the bottom of a dimethyl carbonate de-clogging tower; S1, when the mixture flows into the reaction tower body through the feed pipe, the mixture first falls to the top of the tray and mixes with the upward-moving carbon dioxide. Simultaneously, the motor is started, driving the rotating shaft and the cross sleeve to rotate. The cross sleeve drives the tray to rotate, and then the mixture moves downward along the square cylinder. The heavier substances produced during the reaction fall to the bottom of the inner wall of the reaction tower body and are discharged outward through the discharge pipe; S2, when the rotating shaft rotates, it drives the reciprocating screw to rotate. The reciprocating screw drives the lifting frame to move vertically up and down along the outer wall of the limiting plate. When the lifting frame rises, the lifting frame... The sliding block and vertical rod rise together, which in turn drives the fixed ring and horizontal plate to rise. The horizontal plate then drives the sliding support rod and extrusion plate to rise. When the extrusion plate rises, it contacts and collides with the bottom of the tray, causing the tray to vibrate slightly and preventing particles generated during the reaction from clogging the tray's through holes. S3. As the extrusion plate continues to push the tray upwards, the weight of the tray causes the extrusion plate to drive the sliding support rod to descend vertically along the inner wall of the horizontal plate. As the extrusion plate gradually approaches the horizontal plate, the conical rod at the top of the horizontal plate gradually enters the through hole through the inner wall of the round hole, pushing the particles stuck inside the through hole and moving them to the top of the tray. This effectively clears the particles clogging the through holes.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting up a separation and anti-clogging mechanism, a portion of the condensed liquid at the top of the inner wall of the reaction tower drips onto the top of the arc-shaped ring plate and slides into the reflux pipe, subsequently flowing back into the interior of the reaction tower, thereby achieving a higher purity separation effect. When the mixture flows into the interior of the reaction tower through the feed pipe, it first falls to the top of the tray, mixing and contacting with the upward-moving carbon dioxide. Simultaneously, the motor is activated, driving the rotating shaft and the cross sleeve to rotate. The cross sleeve drives the tray to rotate, ensuring that the mixture at the top of the tray is evenly distributed. This even distribution allows the mixture to fully contact the upward-moving carbon dioxide, increasing the surface area for reaction and facilitating a full reaction between reactants. Subsequently, the mixture moves downward along the square cylinder, and the heavier substances produced during the reaction fall to the bottom of the inner wall of the reaction tower, being discharged outward through the discharge pipe.

[0017] This invention employs a separation and anti-clogging mechanism. When the rotating shaft rotates, it drives a reciprocating screw to rotate, which in turn drives a lifting frame to move vertically up and down along the outer wall of the limiting plate. As the lifting frame rises, it causes the slider and vertical rod to rise, which in turn causes the fixing ring and horizontal plate to rise. The horizontal plate then causes the sliding frame rod and extrusion plate to rise. When the extrusion plate rises, it contacts and collides with the bottom of the tray, causing the tray to vibrate slightly. This effectively prevents particulate matter generated during the reaction from clogging the tray's orifices. It also ensures good contact and mixing between the reactant gas and the liquid mixture, which promotes the conversion rate of the reactants. As the extrusion plate continues to push the tray upwards, the weight of the tray causes the extrusion plate to drive the sliding support rod vertically downwards along the inner wall of the horizontal plate. As the extrusion plate approaches the horizontal plate, the conical rod at the top of the horizontal plate gradually enters the through-hole through the inner wall of the circular hole, pushing out particles stuck inside and moving them to the top of the tray. This effectively clears particles clogging the through-hole, preventing blockages from affecting the smooth operation of gas-liquid reactions or other separation processes. Simultaneously, the lifting frame continuously reciprocates, intermittently cleaning particles from the through-hole, ensuring that even during long-term operation, particle accumulation does not affect the tray's efficiency.

[0018] This invention employs a separation and anti-clogging mechanism. As the tray rotates with the rotating shaft, it drives the vertical rod and slider to rotate within the annular groove. Because the slider continuously rotates within the annular groove in the lifting frame, it prevents jamming during operation. Furthermore, since the vertical rod, fixing ring, horizontal plate, and conical rod rotate with the tray, the conical rod precisely cleans the inner wall of the through-hole. As particles move above the tray, the extrusion plate pushes the tray to the top of the cross sleeve, where the top of the tray contacts the bottom of the cleaning plate. At this point, multiple stationary cleaning plates scrape away the particles on the top of the rotating tray, causing them to fall downwards along the square cylinder, preventing them from falling back into the through-hole. This avoids the need for repeated cleaning, ensuring the continuity and efficiency of the reaction. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As shown in Figures 1 to 10, the present invention provides a dimethyl carbonate de-clogging tower reboiler anti-blocking component, including a reaction tower body 1, a support base 2 fixedly connected to the bottom outer wall of the reaction tower body 1, a feed pipe 3 connected to one side of the top inner wall of the reaction tower body 1, a gas injection pipe 4 connected to one side of the bottom inner wall of the reaction tower body 1, a discharge pipe 5 connected to the bottom of the reaction tower body 1, and exhaust pipes 6 connected to both sides of the top of the reaction tower body 1. The invention also includes: using the above scheme, injecting a mixture into the interior of the reaction tower body 1 through the feed pipe 3 while simultaneously injecting carbon dioxide into the interior of the reaction tower body 1 through the gas injection pipe 4; heating the falling mixture and rising carbon dioxide by the reaction tower body 1; and when the mixture and carbon dioxide in the reaction tower body 1 are heated to a certain temperature during the mixing process, light components will evaporate.

[0023] The separation and anti-blocking mechanism 7 includes a motor 71 fixedly connected to the center of the top of the reaction tower body 1. The output end of the motor 71 is fixedly connected to a rotating shaft 72. Two cross sleeves 73 are fixedly connected to both ends of the outer wall of the rotating shaft 72. The outer wall of the cross sleeves 73 is provided with a separation component 74 for separating the material from dimethyl carbonate.

[0024] Using the above scheme: when the mixture flows into the interior of the reaction tower body 1 through the feed pipe 3, the mixture will first fall to the top of the tray 741 and mix with the upward-moving carbon dioxide. At the same time, the motor 71 is started, and the motor 71 drives the rotating shaft 72 and the cross sleeve 73 to rotate. The cross sleeve 73 drives the tray 741 to rotate, ensuring that the mixture at the top of the tray 741 is evenly spread.

[0025] The separation assembly 74 includes a tray 741 that is slidably connected to the outer wall of the bottom end of the cross sleeve 73. The top of the tray 741 has multiple through holes 742. A square cylinder 743 is fixedly connected to one side of the outer wall of the tray 741. The outer wall of the square cylinder 743 is slidably connected to the inner wall of the reaction tower body 1.

[0026] One end of the discharge pipe 5 passes through and extends to the outside of the support base 2. An arc-shaped ring plate 744 is fixedly connected to the top of the inner wall of the reaction tower body 1. A reflux pipe 745 is connected to the inner wall of the reaction tower body 1 near the top of the arc-shaped ring plate 744. The bottom end of the reflux pipe 745 is connected to the bottom end of the inner wall of the reaction tower body 1.

[0027] Using the above scheme: a portion of the condensed liquid at the top of the inner wall of the reaction tower body 1 will drip onto the top of the arc-shaped ring plate 744 and slide into the interior of the reflux pipe 745, and then flow back into the interior of the reaction tower body 1, thereby achieving a higher purity separation effect.

[0028] An anti-blocking component 75 is provided at the bottom end of the rotating shaft 72. The anti-blocking component 75 includes a reciprocating screw 751 fixedly connected to the outer wall of the bottom end of the rotating shaft 72. A lifting frame 752 is threadedly connected to the outer wall of the bottom end of the reciprocating screw 751.

[0029] Two limiting plates 753 are slidably connected to both sides of the outer wall of the lifting frame 752. One side of the limiting plate 753 is fixedly connected to the inner wall of the reaction tower body 1. An annular groove 754 is provided on the top of the lifting frame 752.

[0030] Two sliders 755 are slidably connected to both ends of the inner wall of the annular groove 754. A vertical rod 756 is fixedly connected to the top of the sliders 755. Two fixing rings 757 are fixedly connected to both ends of the outer wall of the vertical rod 756. Multiple horizontal plates 758 are fixedly connected to the outer wall of the fixing rings 757. A sliding bracket rod 759 is slidably connected through the top of the horizontal plate 758.

[0031] A compression plate 7510 is fixedly connected to the top of the sliding frame rod 759, and a compression spring 7511 is fixedly connected to the bottom of the compression plate 7510. The bottom of the compression spring 7511 is fixedly connected to the top of the horizontal plate 758.

[0032] The above scheme is adopted as follows: When the rotating shaft 72 rotates, the rotating shaft 72 drives the reciprocating screw 751 to rotate. The reciprocating screw 751 drives the lifting frame 752 to move vertically up and down along the outer wall of the limiting plate 753. When the lifting frame 752 rises, the lifting frame 752 drives the slider 755 and the vertical rod 756 to rise. The vertical rod 756 drives the fixing ring 757 and the horizontal plate 758 to rise. The horizontal plate 758 drives the sliding frame rod 759 and the extrusion plate 7510 to rise. When the extrusion plate 7510 rises, it will contact and collide with the bottom of the tray 741, causing the tray 741 to vibrate slightly. This can effectively prevent the particles generated during the reaction process from clogging the through hole 742 of the tray 741.

[0033] As shown in Figures 1 to 10, an auxiliary component 76 is provided on the top of the horizontal plate 758. The auxiliary component 76 includes four tapered rods 761 fixedly connected to the top of the horizontal plate 758, and four round holes 762 are respectively opened on the top of the extrusion plate 7510.

[0034] Using the above scheme: When the extrusion plate 7510 continues to extrude upwards onto the tray 741, the weight of the tray 741 causes the extrusion plate 7510 to drive the sliding support rod 759 to descend vertically along the inner wall of the horizontal plate 758. As the extrusion plate 7510 gradually approaches the horizontal plate 758, the tapered rod 761 at the top of the horizontal plate 758 will gradually enter the interior of the through hole 742 through the inner wall of the round hole 762, pushing the particles stuck inside the through hole 742 and moving the particles to the top of the tray 741, which can effectively clear the particles clogging the through hole 742.

[0035] Two fixed brackets 763 are fixedly connected to both ends of the inner wall of the reaction tower body 1. A circular ring cylinder 764 is fixedly connected to the inner wall of the fixed bracket 763. Multiple cleaning plates 765 are fixedly connected to the outer wall of the bottom end of the circular ring cylinder 764.

[0036] The above-described scheme works as follows: when the particles move above tray 741, the squeezing plate 7510 pushes tray 741 towards the top of the cross sleeve 73, causing the top of tray 741 to contact the bottom of cleaning plate 765. During this process, multiple stationary cleaning plates 765 effectively scrape off the particles from the top of the rotating tray 741, guiding them to the square cylinder 743 and allowing them to fall smoothly. This ensures that the particles do not fall back into the through-hole 742, thus preventing material blockage and ensuring efficient operation of the equipment.

[0037] The working principle and usage process of this invention are as follows: A mixture is injected into the reaction tower body 1 through the feed pipe 3, while carbon dioxide is injected into the reaction tower body 1 through the gas injection pipe 4. The reaction tower body 1 heats the falling mixture and the rising carbon dioxide. During the mixing process, the mixture and carbon dioxide in the reaction tower body 1 are heated to a certain temperature, causing the release of lighter components. Dimethyl carbonate, being a lighter component in the reaction mixture, will evaporate first. The vapor rises in the reaction tower body 1, and as the height increases, the dimethyl carbonate floats to the top of the inner wall of the reaction tower body 1 and condenses into liquid, thus separating the dimethyl carbonate. To improve the separation effect, a portion of the condensed liquid at the top of the inner wall of the reaction tower body 1 drips onto the top of the arc-shaped ring plate 744 and slides into the reflux pipe 745, subsequently flowing back into the reaction tower body 1, thereby achieving a higher purity separation effect. When the mixture flows into the reaction tower body 1 through the feed pipe 3, it first falls to the top of the tray 741, where it mixes and comes into contact with the upward-moving carbon dioxide. Simultaneously, the motor 71 is activated, driving the rotating shaft 72 and the cross sleeve 73 to rotate. The cross sleeve 73 then rotates the tray 741, ensuring the mixture at the top of the tray 741 is evenly distributed. This even distribution allows for sufficient contact between the mixture and the upward-moving carbon dioxide, increasing the surface area for reaction and facilitating a full reaction between the reactants. Subsequently, the mixture moves downwards along the square cylinder 743. Heavier substances produced during the reaction fall to the bottom of the inner wall of the reaction tower body 1 and are discharged outwards through the discharge pipe 5.

[0038] When the rotating shaft 72 rotates, it drives the reciprocating screw 751 to rotate. The reciprocating screw 751 drives the lifting frame 752 to move vertically up and down along the outer wall of the limiting plate 753. When the lifting frame 752 rises, it drives the slider 755 and the vertical rod 756 to rise. The vertical rod 756 drives the fixing ring 757 and the horizontal plate 758 to rise. The horizontal plate 758 drives the sliding frame rod 759 and the extrusion plate 7510 to rise. When the extrusion plate 7510 rises, it will contact and collide with the bottom of the tray 741, causing the tray 741 to vibrate slightly. This effectively prevents particulate matter generated during the reaction from clogging the through holes 742 of the tray 741. This ensures good contact and mixing between the reaction gas and the liquid mixture, which can promote the conversion rate of the reactants. As the extrusion plate 7510 continues to push upwards onto the tray 741, the weight of the tray 741 causes the extrusion plate 7510 to drive the sliding support rod 759 to descend vertically along the inner wall of the horizontal plate 758. As the extrusion plate 7510 gradually approaches the horizontal plate 758, the tapered rod 761 at the top of the horizontal plate 758 gradually enters the through-hole 742 through the inner wall of the circular hole 762, pushing the particles stuck inside the through-hole 742 and moving them to the top of the tray 741. This effectively clears the particles clogging the through-hole 742, preventing blockages from affecting the smooth operation of gas-liquid reactions or other separation processes. Simultaneously, the lifting frame 752 continuously reciprocates, intermittently cleaning the particles inside the through-hole 742, ensuring that the tray 741's efficiency is not affected by particle accumulation over time during long-term operation.

[0039] When the tray 741 rotates with the rotating shaft 72, the tray 741 drives the vertical rod 756 and the slider 755 to rotate within the annular groove 754. Because the slider 755 can continuously rotate within the annular groove 754 in the lifting frame 752, jamming during equipment operation is prevented. Furthermore, since the vertical rod 756, the fixing ring 757, the horizontal plate 758, and the tapered rod 761 rotate with the tray 741, the tapered rod 761 can be precisely aligned with the through hole 7. The inner wall of tray 741 is cleaned. As the particles move above tray 741, the extrusion plate 7510 pushes tray 741 to the top of cross sleeve 73. The top of tray 741 contacts the bottom of cleaning plate 765. At this time, multiple stationary cleaning plates 765 scrape off the particles on the top of the rotating tray 741, causing the particles to fall down the square cylinder 743, ensuring that these particles do not fall back into the through hole 742. This avoids the need for repeated cleaning and ensures the continuity and efficiency of the reaction.

The outer walls of the bottom end of the circular ring cylinder (764) are fixedly connected to multiple cleaning plates (765).

10. A method for preventing clogging in the bottom of a dimethyl carbonate deweighting tower, using the anti-clogging component for the bottom of a dimethyl carbonate deweighting tower as described in claim 8, characterized in that: S1. When the mixture flows into the reaction tower body (1) through the feed pipe (3), the mixture will first fall to the top of the tray (741) and mix with the upward-moving carbon dioxide. At the same time, the motor (71) is started. The motor (71) drives the rotating shaft (72) and the cross sleeve (73) to rotate. The cross sleeve (73) drives the tray (741) to rotate. Then the mixture moves downward along the square cylinder (743). The heavier substances produced during the reaction will fall into the reaction tank. At the bottom of the inner wall of the tower body (1), heavier materials are discharged outward through the discharge pipe (5); S2, when the rotating shaft (72) rotates, the rotating shaft (72) drives the reciprocating screw (751) to rotate, and the reciprocating screw (751) drives the lifting frame (752) to move vertically up and down along the outer wall of the limiting plate (753). When the lifting frame (752) rises, the lifting frame (752) drives the slider (755) and the vertical rod (756) to rise, and the vertical rod (756) drives the fixing ring (755) to rise. 7) The horizontal plate (758) rises, and the horizontal plate (758) drives the sliding frame rod (759) and the extrusion plate (7510) to rise. When the extrusion plate (7510) rises, it will contact and collide with the bottom of the tray (741), causing the tray (741) to vibrate slightly, preventing the particles generated during the reaction from clogging the through hole (742) of the tray (741); S3, when the extrusion plate (7510) continues to squeeze the tray (741) upward, it is subjected to the pressure of the tray (741). The pressure of gravity causes the extrusion plate (7510) to drive the sliding frame rod (759) to descend vertically on the inner wall of the horizontal plate (758). As the extrusion plate (7510) gradually approaches the horizontal plate (758), the conical rod (761) at the top of the horizontal plate (758) will gradually enter the interior of the through hole (742) through the inner wall of the round hole (762), pushing the particles stuck inside the through hole (742) and moving the particles to the top of the tray (741), clearing the particles blocking the through hole (742).
