Abstract
Description
Technical Field
[0001] The present application relates to the technical field of tubular reactors, and in particular to an integrated continuous tubular reactor and process. Background Art
[0002] The integrated continuous tubular reactor is a reaction equipment used in the chemical industry. It consists of one or more long tubular reaction tubes stacked in a spiral shape. It is used to continuously introduce chemicals and catalysts into the reaction tubes so that the chemicals and catalysts can be continuously operated in the reaction tubes. The reactor is characterized by a relatively large length-to-diameter ratio, which can achieve efficient heat transfer and material mixing. The outer wall of the reaction tube is cooled by a coolant so that the reaction can proceed continuously.
[0003] Referring to the Chinese patent document with announcement number CN214716640U and name of continuous flow tubular reactor, the device uses a stirring part to drive the stirring blades to cooperate with the ultrasonic wave emitted by the ultrasonic generator to fully mix the materials, thereby improving the mixing effect, and uses a gas-liquid separation part to separate the gas and liquid produced by the reaction. The separated liquid is returned to the reactor body to continue the reaction, thereby improving the reaction efficiency, solving the problem that the existing tubular reactor has poor reaction mixing effect and low reaction efficiency.
[0004] According to the above technical solution, when the water flow inside the reactor is circulated, a dead water zone exists in the area far away from the circulation port. The existence of the dead water zone causes the water flow in this area to be relatively stationary or flow at a slow rate. During the circulation of the tubular reactor, the liquid exchange efficiency at this position is reduced, resulting in a reduction in the reaction rate of the mixture of chemicals and catalysts passing through this position, which affects the normal progress of the reaction.

DETAILED DESCRIPTION
[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 8 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.
[0038] In the first aspect, the integrated continuous tubular reactor adopts the following technical solutions:
[0039] like Figure 1 and Figure 2 As shown, this embodiment provides an integrated continuous tubular reactor, including a reaction barrel 1, a reaction tube 11, a disturbance mechanism and a filtering system 5. The reaction barrel 1 is placed on a horizontal plane, the reaction tube 11 is fixedly connected inside the reaction barrel 1 and is arranged in a spiral shape, and a disturbance mechanism is arranged at the bottom position of the inner side of the reaction barrel 1. The disturbance mechanism is used to drive the water flow in the dead water area below the reaction barrel 1 away from the water outlet to move, and the filtering system 5 is used to filter impurities in the water flow. By utilizing the impact force of the water flow to drive the components in the disturbance mechanism to rotate, the components drive the water flow in the dead water area away from the water outlet to move, so that the water flow can further move to a place where liquid circulation can be performed.
[0040] like Figure 2As shown, a flow mechanism 2 is arranged at the side wall of the reaction barrel 1, and the flow mechanism 2 includes a reflux bin 21, and the reflux bin 21 is arranged at the side wall of the reaction barrel 1. A reflux port 22 connected to the reflux bin 21 is opened on the side wall of the reaction barrel 1, and the reflux port 22 is arranged at the bottom side wall of the reaction barrel 1, and an outlet port 23 connected to the reflux bin 21 is opened on the side wall of the reaction barrel 1, and the outlet port 23 is arranged at the top side wall of the reaction barrel 1. The liquid at the bottom of the reaction barrel 1 is driven by an external pump to move into the reflux bin 21, and is discharged from the reflux bin 21 into the outlet port 23, and returns to the reaction barrel 1 from the outlet port 23 to perform liquid circulation.
[0041] like Figure 3 As shown, a rotating motor 35 is fixedly connected to the upper position of the reaction barrel 1, and a stirring blade 36 for driving the liquid in the reaction barrel 1 to move downward is fixedly connected to the output shaft of the rotating motor 35. The stirring blade 36 is driven to rotate by the rotation of the rotating motor 35, so that the liquid located above the reaction barrel 1 has a certain impact force, and moves toward the inner bottom position of the reaction barrel 1 under the driving of the impact force.
[0042] like Figure 3 and Figure 4 As shown, a partition plate 4 is fixedly connected to the reaction barrel 1, and the partition plate 4 is arranged above the rotating shaft 3. A partition opening 41 is opened on the partition plate 4, and the partition opening 41 is used to separate the reaction tube 11 and the rotating shaft 3. A partition sleeve 42 is fixedly connected to the partition plate 4, and the partition sleeve 42 is arranged at the partition opening 41. A flow opening 43 for facilitating the flow of liquid is opened on the side wall of the partition sleeve 42.
[0043] like Figure 4 and Figure 5As shown, the disturbance mechanism includes a rotating shaft 3, a receiving plate 31, a stirring sleeve 32 and a receiving blade 34. The rotating shaft 3 is rotatably connected to the inner bottom position of the reaction barrel 1. A plurality of receiving plates 31 are provided, and the plurality of receiving plates 31 are fixedly connected to the axial side wall of the rotating shaft 3. The receiving plate 31 is tilted, and the side of the receiving plate 31 can contact the water flow. The stirring sleeve 32 is rotatably connected to the inner bottom position of the reaction barrel 1. A connecting port 33 is provided at the side wall of the stirring sleeve 32. The connecting port 33 is used for passing the liquid pushed out by the receiving plate 31 when the receiving plate 31 rotates. The receiving blade 34 is fixedly connected to the outer side wall of the stirring sleeve 32. A plurality of receiving blades 34 are provided, and the plurality of receiving blades 34 are tilted on the side wall of the stirring sleeve 32, and the tilt direction of the receiving blade 34 is opposite to the tilt direction of the receiving plate 31. The receiving plate 31 rotates counterclockwise under the impact force of the liquid, and drives the liquid to move toward the connecting port 33 during the rotation. The liquid moves to the stirring sleeve 32 and the receiving blades 34 through the connecting port 33. Since the receiving blades 34 and the receiving plate 31 are inclined in opposite directions, the liquid pushes the receiving blades 34 to drive the stirring sleeve 32 to rotate clockwise, so that the liquid in the dead water area away from the return port 22 moves toward the return port 22 driven by the receiving blades 34.
[0044] like Figure 5 and Figure 6 As shown, the filter system 5 includes a filter screen 51, a collecting block 52 and a cleaning plate 54. The filter screen 51 is fixedly connected to the bottom position of the inner side of the reaction barrel 1. The filter screen 51 is set to be cylindrical and is set in the middle position of the receiving plate 31 and the stirring sleeve 32. The collecting block 52 is fixedly connected to the side wall of the filter screen 51, and a collecting groove 53 is opened in the middle position of the collecting block 52 and the filter screen 51. The collecting groove 53 is used to collect impurities on the filter screen 51. The cleaning plate 54 is rotatably connected to the receiving plate 31. The cleaning plate 54 can abut against the inner side wall of the filter screen 51 and can push the impurities on the inner side wall of the filter screen 51. The liquid impacts the filter screen 51 through the rotation of the receiving plate, and the filter screen 51 isolates the impurities in the liquid. The cleaning plate 54 on the receiving plate rotates with the rotation of the receiving plate, so that the cleaning plate 54 drives the impurities on the side wall of the filter screen 51 to move toward the collecting groove 53 to collect the impurities.
[0045] like Figure 7 and Figure 8As shown, a torsion spring is fixedly connected to the receiving plate 31, and the torsion spring is arranged at the connection between the cleaning plate 54 and the receiving plate 31, the torsion spring is used to drive the cleaning plate 54 to reset, the side wall of the collecting block 52 is rotatably connected to a rotating plate 55, the rotating plate 55 can move toward the inside of the collecting tank 53 under the impact of the water flow, and reset after the impact force of the water flow weakens, to prevent impurities in the collecting tank 53 from flowing out, the bottom position of the reaction barrel 1 is fixedly connected to a collecting bottom plate 6, and the collecting bottom plate 6 is fixedly connected to a cleaning scraper 61 for cleaning impurities in the bottom water flow.
[0046] When the present application is in use, the reaction barrel 1 needs to be filled with liquid first. After the liquid is filled, the chemical substances and catalysts that need to be reacted and cooled are introduced into the reaction tube 11. The chemical substances and catalysts react and release heat in the reaction tube 11. The liquid in the reaction barrel 1 cools the reaction tube 11. During the cooling process, the rotating motor 35 is started so that the output shaft of the rotating motor 35 drives the stirring blades 36 to rotate, and the external pump is started so that the external pump drives the liquid at the bottom of the reaction barrel 1 to move from the reflux port 22 to the outlet port 23.
[0047] The stirring blades 36 rotate to push the liquid to the bottom of the reaction barrel 1. The water flow at the outer wall of the separation sleeve 42 moves to the inner wall of the reaction sleeve through the flow port and continues to move downward. The impact force of the water flow pushes the receiving plate 31 to rotate counterclockwise. During the rotation of the receiving plate 31, the liquid moves toward the connecting port 33 and moves through the connecting port 33 to the cavity between the stirring sleeve 32 and the receiving blades 34. The impact force of the liquid pushes the receiving blades 34 to rotate. The rotation of the receiving blades 34 drives the liquid to move, so that the liquid in the dead water area moves toward the reflux port 22 driven by the receiving blades 34.
[0048] During the rotation of the receiving plate 31, the liquid will pass through the filter screen 51, and the impurities in the liquid will be blocked under the screening of the filter screen 51. The impurities will adhere to the filter screen 51, and the cleaning plate 54 will be driven to move by the rotation of the receiving plate 31, so that the cleaning plate 54 can clean and push the impurities on the side wall of the filter screen 51, and the impurities will move toward the collecting tank 53 driven by the water flow, and after passing through the collecting block 52, the cleaning plate 54 will rotate under the push of the collecting block 52, and the cleaning plate 54 will be reset under the push of the torsion spring, and after passing through the collecting block 52, the rotating plate 55 will move toward the inside of the collecting tank 53 under the impact of the water flow, and reset after the impact force of the water flow weakens.
[0049] In this embodiment, by setting the stirring blades 36 and the partition opening 41 on the partition sleeve 42, the water flow located on the outer wall of the partition barrel is moved toward the inside of the flow receiving plate 31, which can improve the heat exchange efficiency and make the temperature of the material inside the reaction tube 11 more evenly reduced. At the same time, the damage to the connection sealing of the reaction tube 11 caused by excessive impact force of the water flow is reduced.
[0050] In this embodiment, the flow plate 31 and the receiving fan blades 34 are driven to rotate by the water flow. By moving the liquid in the dead water zone, the cooling water can be continuously renewed, thereby improving the cooling efficiency, and the liquid with a higher temperature on the outer wall of the reaction tube 11 can be moved more quickly. In this process, by driving the liquid in the dead water zone to flow, the occurrence of local over-temperature can be prevented, and the temperature of the water flow on the outer wall of the reaction tube 11 can be made uniform by moving the water flow.
[0051] In this embodiment, the rotation speed of the flow receiving plate 31 and the receiving fan blades 34 is controlled by water flow, so that the rotation speed can be adjusted according to the liquid flow rate, avoiding unnecessary energy consumption and improving the overall energy consumption. At the same time, more precise flow control can be performed to meet the needs of different working conditions.
[0052] In this embodiment, since the temperature inside the reaction tube 11 is relatively high, a certain amount of impurities will appear in the liquid when the outside of the reaction tube 11 is cooled. The impurities will affect the heat exchange efficiency during the long-term accumulation. By setting a filter 51 to clean the impurities in the liquid, the normal heat transfer performance of the reaction tube 11 can be ensured to a certain extent, and the cooling effect can be ensured. At the same time, the liquid no longer needs to overcome the heat transfer resistance caused by scale, thereby improving the heat exchange efficiency.
[0053] The implementation principle of the integrated continuous tubular reactor in the embodiment of the present application is as follows: the reaction barrel 1 needs to be filled with liquid first, and after the liquid is filled, the chemical substances and catalysts that need to be reacted and cooled are introduced into the reaction tube 11, and the chemical substances and catalysts react and release heat in the reaction tube 11, and the liquid in the reaction barrel 1 cools the reaction tube 11. During the cooling process, the rotating motor 35 is started so that the output shaft of the rotating motor 35 drives the stirring blades 36 to rotate, and the external pump is started so that the external pump drives the liquid at the bottom of the reaction barrel 1 to move from the reflux port 22 to the outlet port 23.
[0054] The stirring blades 36 rotate to push the liquid to the bottom of the reaction barrel 1. The water flow at the outer wall of the separation sleeve 42 moves to the inner wall of the reaction sleeve through the flow port and continues to move downward. The impact force of the water flow pushes the receiving plate 31 to rotate counterclockwise. During the rotation of the receiving plate 31, the liquid moves toward the connecting port 33 and moves through the connecting port 33 to the cavity between the stirring sleeve 32 and the receiving blades 34. The impact force of the liquid pushes the receiving blades 34 to rotate. The rotation of the receiving blades 34 drives the liquid to move, so that the liquid in the dead water area moves toward the reflux port 22 driven by the receiving blades 34.
[0055] During the rotation of the receiving plate 31, the liquid will pass through the filter screen 51, and the impurities in the liquid will be blocked under the screening of the filter screen 51. The impurities will adhere to the filter screen 51, and the cleaning plate 54 will be driven to move by the rotation of the receiving plate 31, so that the cleaning plate 54 can clean and push the impurities on the side wall of the filter screen 51, and the impurities will move toward the collecting tank 53 driven by the water flow, and after passing through the collecting block 52, the cleaning plate 54 will rotate under the push of the collecting block 52, and the cleaning plate 54 will be reset under the push of the torsion spring, and after passing through the collecting block 52, the rotating plate 55 will move toward the inside of the collecting tank 53 under the impact of the water flow, and reset after the impact force of the water flow weakens.
[0056] In a second aspect, the present application provides an integrated continuous tubular reaction process, wherein the reaction process is:
[0057] S1, filling the reaction barrel 1 with liquid, and introducing the chemical substances and catalysts that need to be cooled by reaction into the reaction tube 11, the reaction between the chemical substances and the catalyst releases heat, introducing liquid into the reaction barrel 1 for cooling, starting the rotary motor 35 and the external pump, and circulating the liquid in the reaction barrel 1;
[0058] S2, the liquid pushes the receiving plate 31 to rotate counterclockwise. During the rotation of the receiving plate 31, the liquid moves toward the connecting port 33. The impact force of the liquid pushes the receiving blade 34 to rotate. Due to the rotation of the receiving blade 34, the water away from the return port 22 is driven to move toward the return port 22;
[0059] S3, during the rotation of the receiving plate 31, the liquid passes through the filter screen 51, and the impurities in the liquid are blocked under the screening of the filter screen 51. The rotation of the receiving plate 31 drives the cleaning plate 54 to move, so that the cleaning plate 54 cleans and pushes the impurities on the side wall of the filter screen 51, and collects the impurities when passing through the collecting groove 53.
[0060] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
