Description

Technical Field

[0001] This invention relates to the field of organosilicon technology, and in particular to a highly efficient catalytic reaction device and catalytic process for organosilicon monomers. Background Technology

[0002] Organosilicon monomers are the core raw materials for synthesizing silicone oil, silicone rubber, silicone resin and other organosilicon materials. Among them, methylchlorosilane (especially dimethyldichlorosilane, abbreviated as M2) accounts for more than 90% of the production. In the industry, the Rochow reaction (direct method) is generally used to achieve efficient catalytic synthesis. Its core is to use chloromethane and silicon powder as raw materials to complete a solid-solid multiphase catalytic reaction under the action of copper-based catalyst.

[0003] The problems commonly encountered in the use of existing high-efficiency catalytic reaction devices for organosilicon monomers are as follows: 1. Insufficient mixing of raw gas with silicon powder and catalyst in the reaction system, resulting in obvious flow dead zones; 2. Inability to remove reaction heat in time, leading to high local temperature fluctuations in the bed and causing silicon powder to sinter and clump together. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art, such as insufficient mixing of raw material gas with silicon powder and catalyst in the reaction system, obvious flow dead zones, inability to remove reaction heat in time, high local temperature fluctuations in the bed, and silicon powder sintering and agglomeration. Therefore, this invention proposes a high-efficiency catalytic reaction device for organosilicon monomers.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency catalytic reaction device for organosilicon monomers includes: a catalytic reactor, a gas distribution structure, a tree-shaped reaction tube structure, an auger feeding structure, a connecting rod feeding structure, and a storage tank.

[0007] The gas distribution structure is set inside the catalytic reactor, which includes a bottom distributor, multiple regularly arranged gas distribution pipes and a gas outlet frame. The distributor is equipped with an inlet pipe extending out of the catalytic reactor, and the gas outlet frame is equipped with a outlet pipe extending out of the catalytic reactor.

[0008] The tree-shaped reaction tube structure includes multiple tree-shaped tubes with branches pointing downwards. The ends of the tree-shaped tubes are connected to the corresponding gas distribution tubes, and the tops of the tree-shaped tubes extend through the catalytic reactor to the outside to transport silicon powder to the gas distribution tubes.

[0009] The connecting rod feeding structure includes a feeding motor, a piston connecting rod mechanism, and multiple feeding cylinders, which are connected to the corresponding tree-shaped tubes.

[0010] The bottom of the storage box is equipped with multiple feeding pipes, which are connected to the upper feeding cylinder, and their connection points are matched with the piston connecting rod mechanism.

[0011] As a further embodiment of the present invention, a heating structure is provided on the catalytic reactor, and the catalytic reactor is filled with heat transfer oil for heating the gas distribution structure. A circulation pump can be provided in the catalytic reactor to accelerate the flow of the heat transfer oil in the catalytic reactor.

[0012] As a further embodiment of the present invention, the two ends of the gas distribution pipe are respectively connected to the distributor and the gas outlet frame. Heat dissipation fins are provided on the outer wall of the gas distribution pipe to accelerate the heat exchange efficiency of the gas distribution pipe. A ventilation pipe for interconnection is provided in the middle of multiple gas distribution pipes. The height of the ventilation pipe is higher than the amount of silicon powder stored in the gas distribution pipe. A support net is provided at the connection between the gas distribution pipe and the distributor to prevent silicon powder from falling into the distributor, so that the silicon powder is concentrated in the gas distribution pipe. Chloromethane enters the gas distribution pipe along the distributor and reacts catalyzed with the silicon powder in the gas distribution pipe.

[0013] As a further embodiment of the present invention, the auger feeding structure includes a feeding motor, a drive gear frame, and multiple auger structures. The feeding motor drives the multiple auger structures using the drive gear frame, and the auger structures are arranged inside the tree-shaped tube.

[0014] As a further embodiment of the present invention, the drive gear frame structure is composed of multiple different gears meshing with each other, including a drive gear set connected to the feeding motor and a passive gear set connected to the auger structure.

[0015] As a further embodiment of the present invention, the auger structure includes multiple auger bodies, which are distributed in different branches of the tree-shaped tube and are connected to each other by bevel gears. The bevel gears are isolated from the auger blades on the auger bodies to prevent unnecessary wear of the bevel gears caused by silicon powder passing through them when the auger bodies are feeding material.

[0016] As a further embodiment of the present invention, the feeding motor is located at the top of the catalytic reactor, the input end of the piston connecting rod mechanism is fixedly connected to the output end of the feeding motor, the output end of the piston connecting rod mechanism is composed of multiple piston blocks, and the feeding cylinder is slidably inserted into the corresponding piston block.

[0017] As a further embodiment of the present invention, a feeding port is provided at the connection between the feeding pipe and the feeding cylinder. The feeding port is matched with the piston block. When the piston connecting rod mechanism moves, the piston block intermittently opens and closes the feeding port.

[0018] As a further embodiment of the present invention, a guide block is provided inside the storage box to guide the material to fall into the feeding pipe, and a storage cover is provided at the top of the storage box. After a specified unit of silicon powder is stored in the storage box, the storage cover is closed.

[0019] A catalytic process for a high-efficiency catalytic reaction device for organosilicon monomers includes the following steps:

[0020] Step 1: Store a specified unit of silicon powder and catalyst mixture (hereinafter referred to as silicon powder) in a storage tank;

[0021] Step 2: The heating structure on the catalytic reactor is activated, and the gas distribution structure is preheated and kept warm by heat transfer oil;

[0022] Step 3: The connecting rod feeding structure is activated, causing the piston block in the piston connecting rod mechanism to move periodically, sending the silicon powder that fell from the storage box into the feeding cylinder into the tree-shaped reaction tube structure;

[0023] Step 4: The auger feeding structure is activated, and the silicon powder is fed from the tree-shaped tube into the gas distribution tube through the auger structure;

[0024] Step 5: Preheated chloromethane is introduced into the distributor. After being distributed by the distributor, it enters the gas distribution pipe and comes into full contact with the silicon powder. The reaction generates a mixed vapor of methylchlorosilane, which is then discharged from the gas outlet frame to the external cyclone separator.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This application achieves quantitative and directional conveying of silicon powder through the coordinated design of the connecting rod feeding structure and the auger feeding structure. The piston block of the connecting rod feeding structure can accurately control the amount of feed per batch by intermittently opening and closing the feeding port, avoiding reaction fluctuations caused by excessive or insufficient silicon powder. The multiple auger bodies of the auger feeding structure operate under the synchronous drive of the drive gear frame. With the branch structure of the tree-shaped tube, the silicon powder can be evenly distributed to each gas distribution pipe, ensuring that the silicon powder concentration in each reaction zone is consistent. This precise and stable feeding method effectively avoids problems such as uneven silicon powder conveying, material interruption or accumulation in traditional devices, ensuring the continuous and stable progress of the catalytic reaction.

[0027] 2. The gas distribution structure in this application adopts a bottom distributor combined with multiple regularly arranged gas distribution pipes. This allows chloromethane to be evenly distributed into each gas distribution pipe through the bottom distributor. At the same time, the tree-shaped reaction tube structure accurately delivers silicon powder into the gas distribution pipes. The support mesh ensures that the silicon powder is concentrated in the gas distribution pipes and comes into contact with the chloromethane. The ventilation pipes (higher than the silicon powder storage) in the middle of the multiple gas distribution pipes allow unreacted chloromethane to circulate between the gas distribution pipes, avoiding the problem of excessively high or low chloromethane concentration in a single gas distribution pipe. This further optimizes the uniformity of gas-solid contact, allowing the two to fully mix and react, effectively improving the conversion rate of raw materials and the generation efficiency of the target product.

[0028] 3. In this application, the heat transfer oil filled in the catalytic reactor serves as the heating medium. Combined with the forced circulation of the circulating pump, the heat can be evenly distributed within the catalytic reactor. The heat dissipation fins on the outer wall of the gas distribution pipe increase the heat exchange area, enabling the gas distribution pipe and the reaction area inside the pipe to quickly and evenly reach the required reaction temperature. This avoids local overheating or underheating. The stable and uniform temperature environment not only ensures the efficient catalytic reaction but also effectively inhibits silicon powder sintering and agglomeration and by-product formation caused by local overheating, thereby improving the selectivity of the target product.

Detailed Implementation

[0038] 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.

[0039] like Figure 1 and Figure 2 As shown, a high-efficiency catalytic reaction device for organosilicon monomers includes: a catalytic reactor 100, a gas distribution structure 200, a tree-shaped reaction tube structure 300, an auger feeding structure 400, a connecting rod feeding structure 500, and a storage tank 600.

[0040] The gas distribution structure 200 is installed inside the catalytic reactor 100, and includes a bottom distributor 210, multiple regularly arranged gas distribution pipes 220 and a gas outlet frame 230. The distributor 210 is provided with an inlet pipe extending out of the catalytic reactor 100, and the gas outlet frame 230 is provided with a discharge pipe extending out of the catalytic reactor 100.

[0041] The tree-shaped reaction tube structure 300 includes multiple tree-shaped tubes 310 with branches pointing downwards. The ends of the tree-shaped tubes 310 are connected to the corresponding gas distribution tubes 220. The tops of the tree-shaped tubes 310 are inserted through the catalytic reactor 100 and extend to the outside for conveying silicon powder to the gas distribution tubes 220.

[0042] The connecting rod feeding structure 500 includes a feeding motor 510, a piston connecting rod mechanism 520 and multiple feeding cylinders 530, with the feeding cylinders 530 connected to the corresponding tree-shaped tubes 310;

[0043] The bottom of the storage bin 600 is provided with multiple feeding pipes 610, which are connected to the upper feeding cylinder 530 and their connection points are matched with the piston connecting rod mechanism 520.

[0044] like Figure 2 As shown, a heating structure is provided on the catalytic reactor 100, and the catalytic reactor 100 is filled with heat transfer oil for heating the gas distribution structure 200. A circulation pump can be installed in the catalytic reactor 100 to accelerate the flow of the heat transfer oil in the catalytic reactor 100.

[0045] like Figure 2 and Figure 3As shown, the two ends of the gas distribution pipe 220 are connected to the distributor 210 and the gas outlet frame 230, respectively. The outer wall of the gas distribution pipe 220 is provided with heat dissipation fins to accelerate the heat exchange efficiency of the gas distribution pipe 220. A vent pipe for interconnection is provided in the middle of multiple gas distribution pipes 220. The height of the vent pipe is higher than the amount of silicon powder stored in the gas distribution pipe 220. A support net is provided at the connection between the gas distribution pipe 220 and the distributor 210 to prevent silicon powder from falling into the distributor 210, so that the silicon powder is concentrated in the gas distribution pipe 220. Chloromethane enters the gas distribution pipe 220 along the distributor 210 and reacts with the silicon powder in the gas distribution pipe 220 to carry out a catalytic reaction.

[0046] like Figure 4 and Figure 5 As shown, the auger feeding structure 400 includes a feeding motor 410, a drive gear frame 420, and multiple auger structures 430. The feeding motor 410 drives the multiple auger structures 430 using the drive gear frame 420. The auger structures 430 are arranged inside the tree-shaped tube 310.

[0047] like Figure 4 and Figure 5 As shown, the drive gear frame 420 structure is composed of multiple different gears meshing with each other, including a drive gear set connected to the feeding motor 410 and a driven gear set connected to the auger structure 430.

[0048] like Figure 4 As shown, the auger structure 430 includes multiple auger bodies 431, which are distributed in different branches of the tree tube 310 and are connected to each other by bevel gears 432. The bevel gears 432 are isolated from the auger blades on the auger bodies 431 to prevent unnecessary wear of the bevel gears 432 when the auger bodies 431 are feeding silicon powder.

[0049] like Figure 6 and Figure 7 As shown, the feeding motor 510 is located at the top of the catalytic reactor 100. The input end of the piston connecting rod mechanism 520 is fixedly connected to the output end of the feeding motor 510. The output end of the piston connecting rod mechanism 520 is composed of multiple piston blocks 521. The feeding cylinder 530 is slidably inserted into the corresponding piston block 521.

[0050] like Figure 6 and Figure 7 As shown, a feeding port 531 is provided at the connection between the feeding pipe 610 and the feeding cylinder 530. The feeding port 531 is matched with the piston block 521. When the piston connecting rod mechanism 520 moves, the piston block 521 intermittently opens and closes the feeding port 531.

[0051] like Figure 1 and Figure 8As shown, the storage bin 600 is equipped with a guide block inside to guide the material into the feeding pipe 610. The top of the storage bin 600 is equipped with a storage cover 620. After a specified unit of silicon powder is stored in the storage bin 600, the storage cover 620 is closed.

[0052] A catalytic process for a high-efficiency catalytic reaction device for organosilicon monomers:

[0053] Step 1: Material preparation and equipment inspection before reaction. The operator opens the storage cover 620 at the top of the storage tank 600 and pours the pre-prepared mixture of silicon powder and catalyst (hereinafter referred to as silicon powder) into the storage tank 600 until the specified storage volume is reached. Then, the storage cover 620 is closed to ensure the airtightness of the storage environment and prevent the silicon powder from getting damp or mixed with impurities. At this time, the guide block inside the storage tank 600 will guide the silicon powder to slide naturally into the multiple feeding pipes 610 at the bottom of the storage tank 600. The end of the feeding pipe 610 is connected to the feeding cylinder 530 of the connecting rod feeding structure 500 one by one to ensure that the silicon powder can accurately enter the feeding area of ​​the feeding cylinder 530. At the same time, the airtightness of each connection part (such as the connection between the air inlet pipe, the discharge pipe and the catalyst vessel 100) is checked to avoid leakage during the subsequent reaction process.

[0054] Step 2: Start the heating system for preheating. Turn on the heating structure on the catalytic reactor 100 to heat the heat transfer oil filled inside the catalytic reactor 100. If the catalytic reactor 100 is equipped with a circulation pump, start the circulation pump simultaneously to accelerate the flow of the heat transfer oil inside the catalytic reactor 100, so as to achieve uniform heating of the heat transfer oil throughout the entire area. During the flow, the heat transfer oil will come into full contact with the gas distribution structure 200 and transfer heat to the bottom distributor 210, gas distribution pipe 220 and gas outlet frame 230 of the gas distribution structure 200 through heat conduction. The heat dissipation fins on the outer wall of the gas distribution pipe 220 can increase the heat exchange area and accelerate the heating rate of the gas distribution pipe 220, so that the entire gas distribution structure 200 gradually reaches the temperature conditions required for the reaction. This process continues to preheat and maintain a stable temperature, providing a suitable thermodynamic environment for the subsequent catalytic reaction.

[0055] Step 3: Start the feeding system to achieve precise delivery of silicon powder. First, turn on the feeding motor 510 of the connecting rod feeding structure 500. The output end of the feeding motor 510 drives the piston connecting rod mechanism 520 to start moving. The output end of the piston connecting rod mechanism 520 consists of multiple piston blocks 521, and each piston block 521 is slidably inserted into the corresponding feeding cylinder 530. When the piston connecting rod mechanism 520 moves, the piston block 521 will slide back and forth in the feeding cylinder 530, thereby intermittently opening and closing the feeding pipe and feeding. When the piston block 521 slides to a position away from the feed port 531 at the connection of the cylinder 530, the feed port 531 opens, and the silicon powder transported from the storage box 600 to the feed cylinder 530 through the feed pipe 610 is unobstructed and falls into the feed chamber of the feed cylinder 530. When the piston block 521 slides in the opposite direction to a position covering the feed port 531, the feed port 531 closes, and the piston block 521 pushes the silicon powder in the feed chamber into the tree-shaped reaction tube structure 300 connected to the feed cylinder 530.

[0056] Step 4: The auger feeding structure 400 is activated to transport silicon powder to the reaction area. The feeding motor 410 of the auger feeding structure 400 is turned on, and the feeding motor 410 drives the drive gear frame 420 to rotate. The rotation of the active gear set eventually drives the passive gear set to rotate synchronously, thereby driving multiple auger structures 430 to start working. The multiple auger bodies 431 of the auger structure 430 are distributed in different branches of the tree-shaped tube 310, and the auger bodies 431 are connected by bevel gears 432. Under the drive of the passive gear set, the auger bodies 431 rotate synchronously, pushing the tree-shaped tube 310 to start working. The silicon powder inside the tube is conveyed downwards along the tube body and finally conveyed to the corresponding gas distribution tube 220 through the downward-facing branch end of the tree-shaped tube 310. During this process, the bevel gear 432 is isolated from the auger blades on the auger body 431. The silicon powder is only conveyed along the tube body under the action of the auger blades and will not come into contact with the bevel gear 432, thus avoiding the scouring and wear of the bevel gear 432 by the silicon powder. At the same time, a support net is provided at the connection between the gas distribution tube 220 and the bottom distributor 210 to prevent the silicon powder from falling into the bottom distributor 210, so that the silicon powder is concentrated and accumulated inside the gas distribution tube 220, creating conditions for the subsequent full reaction with chloromethane.

[0057] Step 5: Introduce the reaction raw materials and carry out the catalytic reaction and product output. Preheated chloromethane to a suitable temperature is introduced into the bottom distributor 210 through the gas inlet pipe extending out of the catalytic reactor 100. The bottom distributor 210 will evenly distribute the chloromethane into multiple regularly arranged gas distribution pipes 220. The chloromethane entering the gas distribution pipe 220 comes into full contact with the silicon powder concentrated inside the pipe under a suitable temperature environment, and a catalytic reaction occurs to generate a mixed vapor of methylchlorosilane. Since the middle of multiple gas distribution pipes 220 are interconnected by a vent pipe, and the height of the vent pipe is higher than the amount of silicon powder stored in the gas distribution pipe 220, the chloromethane that has not fully reacted with the silicon powder can flow between different gas distribution pipes 220 through the vent pipe, so as to achieve a dynamic balance of chloromethane concentration in each gas distribution pipe 220 and ensure that the reaction in each gas distribution pipe 220 can proceed efficiently. As the reaction continues, the mixed vapor of methylchlorosilane gradually accumulates in the gas distribution pipe 220 and flows along the gas distribution pipe 220 to the gas outlet frame 230. Finally, it is discharged through the discharge pipe of the catalytic reactor 100 extending from the gas outlet frame 230 and directly transported to the external cyclone separator for subsequent separation and purification. Throughout the process, all structures work together continuously to achieve continuous feeding of silicon powder and chloromethane, catalytic reaction and continuous output of products, forming a stable continuous production process.

[0058] The beneficial effects of this application are:

[0059] This application achieves quantitative and directional conveying of silicon powder through the coordinated design of the connecting rod feeding structure 500 and the auger feeding structure 400. The piston block 521 of the connecting rod feeding structure 500 can precisely control the amount of feed per batch by intermittently opening and closing the feeding port 531, avoiding reaction fluctuations caused by excessive or insufficient silicon powder. The multiple auger bodies 431 of the auger feeding structure 400 operate under the synchronous drive of the drive gear frame 420. With the branching structure of the tree tube 310, the silicon powder can be evenly distributed into each gas distribution pipe 220, ensuring that the silicon powder concentration in each reaction zone is consistent. This precise and stable feeding method effectively avoids problems such as uneven silicon powder conveying, material interruption or accumulation in traditional devices, ensuring the continuous and stable progress of the catalytic reaction.

[0060] The gas distribution structure 200 in this application employs a bottom distributor 210 combined with multiple regularly arranged gas distribution pipes 220. This design allows chloromethane to be evenly distributed into each gas distribution pipe 220 through the bottom distributor 210. Simultaneously, the tree-shaped reaction tube structure 300 precisely delivers silicon powder into the gas distribution pipes 220. Furthermore, the support mesh ensures that the silicon powder is concentrated within the gas distribution pipes 220 and comes into contact with the chloromethane. The ventilation pipes (higher than the silicon powder storage) located in the middle of the multiple gas distribution pipes 220 allow unreacted chloromethane to circulate between the gas distribution pipes 220, avoiding the problem of excessively high or low chloromethane concentrations in a single gas distribution pipe 220. This further optimizes the uniformity of gas-solid contact, enabling the two to fully mix and react, effectively improving the conversion rate of raw materials and the generation efficiency of the target product.

[0061] In this application, the heat transfer oil filled in the catalytic reactor 100 serves as the heating medium. Combined with the forced circulation of the circulating pump, heat can be evenly distributed within the catalytic reactor 100. The heat dissipation fins on the outer wall of the gas distribution pipe 220 increase the heat exchange area, enabling the gas distribution pipe 220 and the reaction area inside the pipe to quickly and evenly reach the temperature required for the reaction. This avoids the phenomenon of excessively high or low local temperatures. The stable and uniform temperature environment not only ensures the efficient progress of the catalytic reaction but also effectively inhibits the sintering and agglomeration of silicon powder and the generation of by-products caused by local overheating, thereby improving the selectivity of the target product.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
