Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, and in particular to a continuous reaction device and reaction system for fine chemical production. Background Technology

[0002] Fine chemical products refer to chemical products with specific applications, high technology intensity, strong commercial value, and high added value, and are gradually being widely used in daily production activities. Some fine chemical product production processes require mixing and chemical reactions.

[0003] In existing technologies, vertical containers are often used as reaction vessels for fine chemical products. By installing a heating base at the bottom of the vertical container, the reaction vessel is equipped with a heating function to promote the chemical reaction. However, the internal temperature field distribution of this type of vertical reaction vessel is uneven, resulting in a low reactant synthesis rate; its internal material flow is poor, resulting in a long reaction time. Summary of the Invention

[0004] In response to the shortcomings of the existing production technologies, the applicant provides a reasonably structured continuous reaction device and reaction system for fine chemical production. This system can provide a stable and uniform temperature field environment for the mixture within the continuous reaction device, thereby improving the reactant synthesis rate. At the same time, it can promote the fluidity of the mixture inside, greatly shortening the reaction time.

[0005] The technical solution adopted in this invention is as follows:

[0006] A continuous reaction apparatus for fine chemical production includes a vibrator supported by a mounting platform. The working end of the vibrator is fitted with a mounting frame, and several independent reaction tubes are mounted on the mounting frame. The reaction tubes contain a mixture of materials.

[0007] The structure of a single reaction tube is as follows: it includes an inner hollow outer tube, several first interfaces are provided on the side wall of the outer tube, end caps are respectively installed at both ends of the outer tube, a second interface is provided on a single end cap, and a dynamic tube is installed inside the outer tube;

[0008] The vibrator generates vibration, which drives the reaction tube to vibrate through the mounting frame, thereby causing the dynamic tube to agitate the mixture inside the reaction tube.

[0009] As a further improvement to the above technical solution:

[0010] The inner wall of a single outer tube has a cavity.

[0011] The single dynamic tube is hollow inside, and several through holes are provided on the wall surface.

[0012] The vibrator is an ultrasonic vibrator.

[0013] The mounting frame has the following structure: it includes a fixed frame connected to the working end of the vibrator, and an array of support components is fixed to the top of the fixed frame. Each set of support components includes several support base assemblies stacked vertically.

[0014] The structure of a single support assembly is as follows: it includes an upper support and a lower support that are fitted together. The bottom of the upper support has a first concave surface, and the top of the lower support has a second concave surface corresponding to the first concave surface.

[0015] The top of the mounting frame is equipped with a protective railing.

[0016] A reaction system based on the above-mentioned continuous reaction device for fine chemical production includes a temperature control device, which is connected to a first heat preservation device and a second heat preservation device respectively. The temperature control device adjusts the output temperature of the first heat preservation device and the second heat preservation device according to the temperature requirements of the reaction system.

[0017] The first heat preservation device evenly wraps the outer wall of each reaction tube. One of the first ports of a reaction tube is used for feeding material A, and one of the second ports is used for feeding material B.

[0018] One of the second ports of the other reaction tube is connected to an external gas source through a delivery pipe assembly, and a second heat insulation device is evenly wrapped on the outer wall of the delivery pipe assembly.

[0019] The reaction tubes in the continuous reaction device are connected by a connecting pipe assembly, so that the mixture in one reaction tube flows into another reaction tube;

[0020] When multiple reaction tubes are connected by a connecting pipe assembly, the gas source provides positive pressure, thereby driving the flow of the mixture inside the reaction tubes.

[0021] As a further improvement to the above technical solution:

[0022] Both the first insulation device and the second insulation material use electric heat tracing tape.

[0023] The temperature control device includes a PLC.

[0024] The beneficial effects of this invention are as follows:

[0025] The continuous reaction apparatus of the present invention, by setting up a reaction tube and a vibrator, can enhance the fluidity of the mixture inside the reaction tube, promote the full mixing and reaction of the mixture, thereby effectively improving the reactant synthesis rate and greatly shortening the reaction time.

[0026] The continuous reaction apparatus of the present invention allows the reaction tubes to be used independently, thereby enabling multiple chemical reactions to occur simultaneously in different reaction tubes; it also allows multiple reaction tubes to be connected together for use, thus enabling it to handle situations with large quantities of materials.

[0027] The reaction system of the present invention, by setting up a temperature control device, a first heat preservation device and a second heat preservation device, stabilizes the temperature inside the reaction tube, thereby enabling the mixture to react in a stable temperature environment, thus effectively improving the reactant synthesis rate.

[0028] The reaction system of the present invention ensures the uniformity of the internal temperature of each reaction tube by uniformly wrapping the outer wall of each reaction tube with the first heat preservation device, thereby preventing the problem of inconsistent synthesis rate caused by uneven temperature of the mixture inside the reaction tube.

[0029] The reaction system of the present invention has a compact and reasonable structure, is easy to operate, and its internal reaction tubes are independent of each other. The temperature inside the reaction tubes can be independently controlled by the temperature control system. Furthermore, by setting up connecting pipe groups, multiple reaction tubes can be used in combination. It has flexible usage, low requirements for the installation environment, low manufacturing cost, and strong applicability. Attached Figure Description

[0040] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0041] Example 1:

[0042] like Figures 2-7 As shown, the continuous reaction apparatus for fine chemical production in this embodiment includes a vibrator 3, which is supported by a mounting platform 4. A mounting frame 2 is installed at the working end of the vibrator 3, and several independent reaction tubes 1 are installed on the mounting frame 2. The reaction tubes 1 contain a mixture. The structure of a single reaction tube 1 is as follows: it includes an inner hollow outer tube 101, several first interfaces 106 are provided on the side wall of the outer tube 101, and end caps 103 are respectively installed at both ends of the outer tube 101. A second interface 107 is provided on each end cap 103. A dynamic tube 102 is installed inside the outer tube 101. The vibrator 3 generates vibration, which drives the reaction tube 1 to vibrate through the mounting frame 2, thereby causing the dynamic tube 102 to stir the mixture in the reaction tube 1.

[0043] The continuous reaction apparatus of this embodiment includes a reaction tube 1, a mounting frame 2, a vibrator 3, and a mounting platform 4;

[0044] Mounting platform 4 is used to provide a horizontal installation environment for the continuous reaction unit. The top of the mounting platform 4 is fixed with vibrator 3, the working end of vibrator 3 facing upward, and connected to mounting frame 2. Mounting frame 2 is equipped with several reaction tubes 1 through support base assembly.

[0045] The vibrator 3 is an ultrasonic vibrator used to drive the reaction tube 1 to vibrate, thereby causing the mixture in the reaction tube 1 to vibrate and accelerate the reaction. At the same time, the dynamic tube 102 in the reaction tube 1 shakes, thereby agitating the mixture in the outer tube 101 and further promoting the reaction of the mixture.

[0046] A cavity 104 is provided inside the wall of the single outer tube 101. The cavity 104 is used for heat insulation, which can keep the internal temperature of the outer tube 101 stable, thereby ensuring that the mixture reacts evenly and completely.

[0047] The single dynamic tube 102 is hollow inside, and several through holes 105 are provided on the wall surface. The through holes 105 can further enhance the flowability of the mixture inside the outer tube 101, thereby accelerating the reaction and shortening the reaction time.

[0048] The structure of the mounting frame 2 is as follows: it includes a fixed frame 201 connected to the working end of the vibrator 3. An array of support components is fixed to the top of the fixed frame 201. Each support component includes several support base assemblies stacked vertically. A single support base assembly consists of an upper support base 202 and a lower support base 203 that are fitted together. The bottom of the upper support base 202 has a first concave surface 204, and the top of the lower support base 203 has a second concave surface 205 corresponding to the first concave surface 204. A protective railing is installed on the top of the fixed frame 201. In this embodiment, both the outer tube 101 and the dynamic tube 102 are cylindrical. The first concave surface 204 and the second concave surface 205 correspond to the shape of the outer wall surface of the outer tube 101, thereby enabling the support base assembly to fit well against the outer wall surface of the outer tube 101 to support and fix the reaction tube 1.

[0049] To ensure the stability of the reaction tube 1 during vibration, the inner diameter of the circular through hole formed by the combination of the first concave surface 204 and the second concave surface 205 is equal to or slightly larger than the outer diameter of the outer tube 101, so that the support assembly can clamp and fix the reaction tube 1, and the length of the support assembly should not be less than one-third of the length of the side wall of the outer tube 101.

[0050] The number of support assemblies is determined by the number of reaction tubes. By stacking the support assemblies, the structure of the continuous reaction device can be made more compact, reducing its footprint.

[0051] In this embodiment, the first interface 106 and the second interface 107 on the end cap 103 are used for the inlet and outlet of the mixture and the connection between different reaction tubes 1; they can also be used to connect to an external gas source 5.

[0052] In this embodiment, depending on the requirements of the mixture in the reaction tube 1, the reaction tube 1 can be used independently, that is, only one reaction tube 1 is used to complete the reaction of the mixture; or multiple reaction tubes 1 can be connected by a connecting pipe group, and one of the reaction tubes 1 can be connected to the gas source 5, so that the mixture circulates in multiple reaction tubes 1 until the reaction is completed, and then the mixture is discharged through the first interface 106 or the second interface 107 on one of the reaction tubes 1 to the external pipeline.

[0053] In this embodiment, during the use of the continuous reaction device, the unused first interface 106 and second interface 107 are sealed with plugs.

[0054] The mixture in this embodiment includes material A7 and material B8.

[0055] Example 2:

[0056] like Figure 1 As shown, based on the continuous reaction apparatus for fine chemical production provided in Embodiment 1, this embodiment provides a reaction system;

[0057] The reaction system of this embodiment includes a temperature control device 6, which is connected to a first insulation device and a second insulation device. The temperature control device 6 adjusts the output temperature of the first insulation device and the second insulation device according to the temperature requirements of the reaction system. The first insulation device evenly wraps the outer wall of each reaction tube 1. One of the first ports 106 of one reaction tube 1 is used for feeding material A7, and one of the second ports 107 is used for feeding material B8. One of the second ports 107 of another reaction tube 1 is connected to an external air source 5 through a conveying pipe group 9. The outer wall of the conveying pipe group 9 is evenly wrapped with a second insulation device. The reaction tubes 1 in the continuous reaction device are connected by a connecting pipe group, so that the mixture in one reaction tube 1 can flow into another reaction tube 1. When multiple reaction tubes 1 are connected by the connecting pipe group, the air source 5 provides positive pressure, thereby promoting the flow of the mixture in the reaction tube 1.

[0058] In this embodiment, by setting up a temperature control system, the temperature inside the reaction tube 1 is adjustable and can be kept stable, thereby improving the reactant synthesis rate of the mixture inside the reaction tube 1.

[0059] The temperature control system includes a temperature control device 6, a first insulation device, and a second insulation device. The temperature control device 6 includes a PLC. Both the first insulation device and the second insulation device are made of electric heating tape. The electric heating tape is equipped with a temperature sensor, which can detect the wall temperature of the reaction tube 1 and the wall temperature of the delivery tube group 9, respectively. The PLC controls the output temperature of the electric heating tape according to the temperature parameters detected by the temperature sensor, thereby ensuring the temperature inside the reaction tube 1 is stable.

[0060] In this embodiment, the gas pressure provided by the gas source 5 needs to be separated by water and liquid to ensure dryness, and can only be delivered to the corresponding reaction tube 1 after reaching the set temperature.

[0061] The reaction system in this embodiment operates as follows:

[0062] Start the temperature control device 6, and control the output temperature of the first and second heat preservation devices through the temperature control device 6, so as to preheat the reaction tube 1 and the delivery tube group 9 respectively.

[0063] After preheating, feed the material.

[0064] Material A7 enters the interior of the outer tube 101 through the first interface 106, while material B8 enters the interior of the outer tube 101 through the second interface 107.

[0065] Inside the outer tube 101, materials A7 and B8 are mixed and reacted to form a mixture.

[0066] During the mixing and reaction of materials A7 and B8, the PLC adjusts the output temperature of the first and second heat preservation devices according to the reaction requirements, so that the temperature inside the reaction tube 1 reaches the required temperature.

[0067] Subsequently, the temperature control device 6 dynamically adjusts the output temperature of the first and second insulation devices according to the temperature parameters collected by the temperature sensor, so that the temperature inside the reaction tube 1 remains stable.

[0068] When the amount of material to be processed in the reaction system is large, multiple reaction tubes 1 are connected by connecting pipe groups, and one of the second ports 107 of one of the reaction tubes 1 is connected to an external air source 5 through a conveying pipe group 9. The external air source 5 provides positive pressure to the mixture in the reaction tube 1, pushing it to circulate in multiple reaction tubes 1.

[0069] Once the temperature inside the reaction tube 1 reaches the required temperature, the vibrator 3 is turned on to make the reaction tube 1 vibrate. At the same time, the dynamic tube 102 moves inside the outer tube 101, thereby agitating the mixture inside the reaction tube 1 and promoting the reaction process.

[0070] Once the preset reaction time is reached, the material is discharged by connecting the first interface 106 or the second interface 107 on one of the reaction tubes 1 through an external pipeline.

[0071] Figure 1 The arrows in the diagram indicate the feeding and discharging directions of the mixture inside the reaction tube 1 in this embodiment.
