Description

Technical Field

[0001] The invention relates to the field of chemistry, in particular to a vertical dynamic tubular reactor and a vertical dynamic tubular reaction system having the vertical dynamic tubular reactor. Background Art

[0002] The purpose of the dynamic tubular reactor is to replace the existing CSTR in the laboratory. CSTR connects multiple reaction bottles in series through PFA tubes. The depth of the tube insertion is related to the retention time of the reaction. Nitrogen is used as the power source. When the liquid level reaches the depth of the tube insertion, the liquid is pushed to the next bottle under the action of nitrogen until the final product bottle. CSTR is mainly aimed at reactions involving or generating solids to solve the problem of easy clogging with coils. The CSTR solution itself has certain safety issues. When the reaction produces severe gas, the bottle stopper will pop open instantly, causing chemical reagents to splash and posing a risk of injury.

[0003] The dynamic tubular reactor with the same specifications as CSTR in the prior art is very large, occupying about 3 / 4 of the size of the fume hood, so it is difficult to connect multiple devices in series, or multiple fume hoods need to be occupied to achieve the work of connecting multiple devices in series, which leads to the problem of low space utilization of the fume hood. The dynamic tubular reactor is mainly used for reactions involving or generating solids, which requires the equipment to be easy to disassemble and assemble. However, the disassembly of equipment on the market has high requirements for experimental personnel. The maintenance of a device takes about half a day or more. It is easy to cause leakage of the equipment due to improper operation. Some equipment even needs to be returned to the factory for maintenance. In this way, urgent projects are often terminated due to equipment problems, which is particularly unfriendly to experimental personnel.

[0004] In addition, dynamic tubular reactors also have to perform some reactions with relatively serious gas production, so accurate retention time must be solved. In the prior art, dynamic tubular reactors are all arranged horizontally. Horizontal arrangement of dynamic tubular reactors is prone to the problem of unreacted materials being pushed out of the reactor due to sudden gas production, thus failing to solve the retention time problem.

[0005] With the advancement of technology, vertical dynamic tubular reaction system has emerged. Vertical dynamic tubular reaction system is a reaction jacket arranged vertically, and materials and heat exchange medium are in the bottom and out the top. However, the problem brought by the vertical reactor is that the back mixing is relatively serious. When some reactions are seriously back mixed, by-products will be produced, which is also the result that the experimenters do not want to get. The vertical structure of the vertical dynamic tubular reaction system also brings new technical problems, that is, the vertical dynamic tubular reaction system is prone to form a large temperature difference between the top and the bottom, and it is easy to form a dead zone, thus affecting the experimental results. Summary of the invention

[0006] A series of simplified concepts are introduced in the Summary of the Invention, which are all simplifications of the prior art in the field, and will be further described in detail in the Detailed Description of the Invention.

[0028] A control unit, which pre-stores control instructions, which selects control instructions according to input parameters to control the vertical support drive unit 20, and performs alarms and emergency shutdowns according to specified sensor feedback parameters;

[0029] A vertical support driving unit 20, which is used to support the vertical dynamic tubular reactor 19 and drive the reaction stirring shaft 9 of the vertical dynamic tubular reactor 19;

[0030] The vertical dynamic tubular reactor 19 is used to provide a reaction space and a reaction environment, and stirs the reaction materials through the reaction stirring shaft 9 to perform the reaction.

[0031] Preferably, the vertical dynamic tubular reaction system is further improved, further comprising:

[0039] And, a parameter input device formed on the control box.

[0040] Preferably, the vertical dynamic tubular reaction system is further improved, and the vertical support driving part 20 is formed as a support driving frame.

[0041] The working principle and technical effects of the vertical dynamic tubular reactor of the present invention are as follows:

[0042] Each structure of the vertical dynamic tubular reactor of the present invention can be set as a modular structure, so it is convenient to disassemble and assemble, and can be completed by ordinary experimenters. The vertical dynamic tubular reactor of the present invention is small in size, easy to operate, and has high-quality mass transfer and heat transfer effects, thereby greatly shortening the reaction time, and is very suitable for high-risk reactions with high mixing effect requirements, sensitivity to backmixing, large-scale gas production, and solid participation or generation.

[0043] The vertical dynamic tubular reactor of the present invention forms an annular reaction zone through structural design of the inner surface of the reaction chamber and the reaction stirring shaft. By arranging a thermal insulation layer and designing the heat exchange layer on the side close to the inner wall of the shell, since the radius on the side close to the inner wall of the shell is relatively large, the heat exchange area can be expanded to improve the heat exchange efficiency.

[0044] The vertical dynamic tubular reactor of the present invention is designed with two giving way structures, so that the temperature monitoring point is closer to the middle part of the shaft body and has a gap with the heat exchange interlayer, so that the temperature measurement is more accurate.

[0045] It should be noted that the present invention also carries out structural design for the stirring shaft of the vertical dynamic tubular reactor. The lower end of the shaft body of the reaction stirring shaft of the present invention is welded with spiral blades, comb teeth are welded in the radial direction of the upper end, and anti-fall baffles are welded between the comb teeth of the stage length. When there are solid particles or suspension in the reaction liquid, when the lower end of the reaction liquid enters the reaction chamber, the spiral blades of the rotating shaft rotate at high speed to generate an upward force to push the material to the comb tooth area. The rapid rotation of the comb teeth makes the mixing effect of the two streams of materials extremely good. Due to gravity, the liquid has a tendency to fall. At this time, the anti-fall baffle plays a role in preventing it from falling. The upward thrust of the external spiral effectively solves the reaction that is more sensitive to back mixing. At the same time, the temperature monitoring point directly measures the temperature of the reaction liquid through the heat exchange layer, and the temperature measuring point is arranged in the middle part of the reaction cavity. The middle part is the flow area of ​​the reaction liquid, so the measured temperature is more accurate.

[0046] The reaction stirring shaft of the present invention effectively solves a type of reaction that is sensitive to back-mixing through the design of the first stirring structure, the second stirring structure and the third stirring structure. The combination of the first stirring structure, the second stirring structure and the third stirring structure effectively solves the problem of shaft obstruction caused by material deposition without affecting the mixing effect. Each structure of the present invention can be set as a modular structure, so it is relatively convenient to disassemble and assemble, and can be completed by ordinary experimenters. The present invention is small in size, easy to operate, and has high-quality mass transfer and heat transfer effects, thereby greatly shortening the reaction time. It is very suitable for high-risk reactions with high mixing effect requirements, sensitivity to back-mixing, large-scale gas production, and solid participation or generation.

[0047] The first stirring structure, the second stirring structure and the third stirring structure of the reaction stirring shaft of the present invention are preferably used in combination, and can also be used separately, the difference only being that the technical effects are slightly different.

[0048] The working principle of the vertical dynamic tubular reaction system of the present invention is as follows:

[0049] For the input parameters of the control unit of the vertical dynamic tubular reaction system of the present invention, the controller queries the pre-stored instructions according to the input parameters, such as querying the calibration table according to the input parameters. The exemplary calibration table is a relationship table between the input parameters, the driving time of the vertical support driving unit, the driving mode of the vertical support driving unit, the reaction time and the control instructions of the vertical support driving unit. The vertical support driving unit can be controlled according to the input parameters, thereby realizing fully automatic completion of the reaction, avoiding possible misoperation caused by manual operation, and realizing standardized production to improve product uniformity.

[0050] Furthermore, by collecting designated sensor parameters, the present invention can monitor the entire reaction process according to preset designated thresholds, and output an alarm or perform an emergency shutdown if an uncontrollable condition occurs, thereby improving the safety of reaction production and reducing uncontrollable risks.

[0110] The control unit includes a controller arranged in a control box 21, which pre-stores control instructions, and selects control instructions according to input parameters to control the vertical support drive unit 20, and executes alarms and emergency shutdowns according to specified sensor feedback parameters; the controller can be a host computer, MCU, PC, etc.; the specified sensor can be a temperature sensor at a temperature monitoring point and a pressure sensor at a specified position. For example, when the temperature is greater than a first specified temperature threshold, an alarm is issued to notify the staff; if the temperature exceeds a second specified temperature threshold, the system executes an emergency shutdown (all equipment is powered off and stops working); the principle of alarming and emergency shutdown according to pressure is the same as that of temperature control, and will not be repeated. Accordingly, temperature and pressure can be used alone or in combination to execute control.

[0111] In addition, a parameter input device 22 is formed on the control box. The input device 22 can be a keyboard, a touch screen, etc., and there is a display part for displaying the currently executed instructions, reaction temperature, vertical dynamic tubular reactor speed and other parameters that need to be monitored; this embodiment uses a touch screen that can be used as a parameter input device and can also display parameters.

[0112] A vertical support drive unit 20, which is formed as a support drive frame, is used to support the vertical dynamic tubular reactor 19 and drive the reaction stirring shaft 9 of the vertical dynamic tubular reactor 19; for example, the transmission structure 3 of the reaction stirring shaft 9 is driven by the motor gearing;

[0113] A vertical dynamic tubular reactor 19 is used to provide a reaction space and a reaction environment, and stirs the reaction materials through a reaction stirring shaft 9 to perform a reaction;

[0114] Preferably, the input parameters include: at least one of: reaction environment temperature, reaction time, reaction inert atmosphere, reaction pressure, reaction liquid type, reaction liquid amount and reaction type;

[0115] The input parameters are the basis for the control unit to query the control instructions, that is, the input parameters trigger the selection of the control instructions of the control unit, and the control instructions are obtained by querying the calibration table according to the input parameters.

[0116] Exemplarily, the input parameters include: reaction environment temperature, reaction time, reaction inert atmosphere, reaction pressure, reaction liquid type, reaction liquid volume and reaction type; it should be noted that the above parameters are only examples of commonly used parameters considered by the applicant, and these parameters can be combined as input parameters or used as input parameters separately.

[0117] More specifically, the following are some examples:

[0118] 1. Input parameter reaction type A, then query control instruction B according to reaction type A. Control instruction B is to drive the vertical dynamic tubular reactor to stir clockwise for C seconds.

[0119] 2. Input parameters of reaction type A and reaction time D, then query control instruction B according to reaction type A and reaction time D. Control instruction F is to drive the vertical dynamic tubular reactor to stir clockwise for C seconds and counterclockwise for C seconds.

[0120] 3. Input parameters of reaction type A, reaction time D, and reaction liquid type E. Then query control instruction G according to reaction type A, reaction time D, and reaction liquid type E. Control instruction G is to drive the vertical dynamic tubular reactor to stir for C seconds and counterclockwise for H seconds. Similarly, the relationship table between input parameters and control instructions is established through calibration, and then fully automatic reaction control is realized after inputting parameters.

[0121] It should be noted that electric control valves can also be set at the heat exchange medium inlet 17, the heat exchange medium outlet 18, the reaction liquid inlet 10, and the product outlet 11, and integratedly controlled by the controller, so that manual operation can be completely eliminated not only during the reaction process, but also in the feeding and output stages.

[0122] For example, if the reaction environment temperature is found to be low, the electric control valve of the heat exchange medium inlet 17 is opened to raise the temperature. After the reaction is completed, the electric control valve of the product outlet 15 is opened, and the product pump is started by the control unit to extract the product.

[0125] The reaction liquid supply module 24 is formed with at least one reaction liquid supply path with a driving device, which is connected to the reaction liquid inlet 14; for example, the reaction liquid in the raw material bottle 24.1 is extracted and input into the reaction liquid inlet 14 through the peristaltic pump 24.2 as a driving device, and the pressure at the outlet of the peristaltic pump is monitored and fed back to the controller to determine whether there is a blockage in the system pipeline. If blockage occurs, the outlet pressure of the peristaltic pump is greater than the first specified pressure threshold, and an alarm is issued to notify the staff; if the outlet pressure of the peristaltic pump is greater than the second specified pressure threshold, the system performs an emergency shutdown (all equipment is powered off and stops working), and a bypass pipeline can be considered to be set for pressure relief accordingly;

[0126] The temperature control module 25 has an outlet connected to the heat exchange medium inlet 17 of the heat exchange interlayer 12, and an inlet connected to the heat exchange medium outlet 18, and is used to provide a heat exchange medium at the temperature required for the reaction; for example, the heat exchange medium is circulated and temperature-controlled and inputted into the heat exchange medium inlet 17 through a circulating bath device, and then inputted back into the circulating bath device through the heat exchange medium outlet 18 for cyclic heating; and the temperature of the temperature monitoring point is monitored and fed back to the controller to determine whether the system is overheated and thus an uncontrollable reaction condition may occur. If overheating occurs, the temperature of the temperature monitoring point is greater than the first specified temperature threshold, and an alarm is issued to notify the staff; if the temperature of the temperature monitoring point is greater than the second specified temperature threshold, the system executes an emergency shutdown (all equipment is powered off and stops working), and accordingly, a cooling device can be considered to be set to cool the reactor;

[0127] The product module 26 is connected to the product outlet 15 and is used to collect the reaction products.
