Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of reactor-related technology, specifically to a reactor for direct chemical energy recovery and power generation in a medium- and high-pressure reaction system. Background Technology

[0002] In chemical production, many medium- and high-pressure reaction systems (such as syngas to methanol) involve intense exothermic reactions. During a chemical reaction, the energy difference generated by the breaking and recombination of chemical bonds is usually released as heat. If the heat of reaction is not removed in time, it will lead to an abnormal increase in system temperature, which will not only affect the reaction equilibrium and product selectivity, but may also cause safety hazards such as catalyst deactivation, equipment over-temperature and over-pressure, seriously restricting the stable operation of production.

[0003] Currently, traditional heat transfer methods mostly employ indirect heat exchange (such as jacketed cooling and coil heat exchange), which requires the transfer of heat through an intermediate medium, resulting in problems such as low heat transfer efficiency and large heat loss. At the same time, the large amount of waste heat generated by the reaction is usually directly discharged or used only for low-grade heating, failing to achieve efficient recovery and utilization, thus causing energy waste.

[0004] Given the unique characteristics of medium- and high-pressure reaction systems, existing equipment has significant shortcomings in terms of sealing performance, adaptability to high-pressure environments, and direct conversion of heat energy, making it difficult to simultaneously achieve stable temperature control of the reaction process and efficient recovery and power generation of chemical energy. Therefore, developing an integrated reactor capable of directly recovering reaction heat and converting it into electrical energy under medium- and high-pressure conditions is crucial to solving these problems. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a reactor for direct recovery of chemical energy for power generation in a medium- and high-pressure reaction system. This solves the technical problems of traditional heat transfer methods in the prior art, which mostly use indirect heat exchange (such as jacket cooling, coil heat exchange, etc.), which require heat transfer through an intermediate medium, resulting in low heat transfer efficiency and large heat loss.

[0006] According to one aspect, at least one embodiment of this disclosure provides a reactor for direct chemical energy recovery and power generation in a medium-high pressure reaction system, comprising: A pair of high-pressure reactor shells, a spliced ​​shell, and a pair of conductive rods, wherein the conductive rods are all disposed inside the high-pressure reactor shells and the spliced ​​shells, and the high-pressure reactor shells and the spliced ​​shells are fixedly connected by screws and bolts; A flow-blocking assembly is disposed at both ends of the high-pressure reactor shell; A filler support assembly is disposed between the conductive rods; The packing support assembly includes a pair of cylinders, both of which are disposed inside the shell of the high-pressure reactor. Each cylinder is fitted with a sealing component, and a sealing support block is inserted into both ends of the sealing component. The pair of sealing support blocks are respectively supported at both ends of the cylinder.

[0007] As a further technical solution, each of the sealing support blocks has an insertion hole on its surface, and the conductive rod is inserted into the insertion hole of one of the sealing support blocks. A conductive rod is inserted and connected between the insertion holes of a pair of sealing support blocks with opposite cylinders.

[0008] As a further technical solution, the blocking and flow assembly includes a high-pressure reactor inlet pipe and a high-pressure reactor outlet pipe, wherein the high-pressure reactor inlet pipe and the high-pressure reactor outlet pipe are respectively connected to both ends of the outer wall of the high-pressure reactor shell.

[0009] As a further technical solution, the outer walls at both ends of the high-pressure reactor shell are provided with protruding layers, and sealing sleeves are fitted at both ends of the high-pressure reactor shell, through which the conductive rod passes.

[0010] As a further technical solution, a connecting sleeve is fitted outside the sealing sleeve, and the connecting sleeve is connected to the outer wall of the outer convex layer by threaded connection. The sealing sleeve has a T-shaped cross-section, with one end passing through the connecting sleeve.

[0011] As a further technical solution, a sealing sleeve is installed at one end of the conductive rod, a fastening bolt is connected to one end of the conductive rod by threaded screwing, and a terminal block is provided at one end of the conductive rod.

[0012] As a further technical solution, one end of the conductive rod and both ends of the conductive rod are tapered structures.

[0013] As a further technical solution, the cylinder is a cylindrical structure made of ceramic material, and the cylinder can be filled with material, which is a sintered material or a loosely packed granular material.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the packed support assembly solves the problem of low efficiency in traditional indirect heat exchange through integrated design. The ceramic cylinder is resistant to high pressure and high temperature, providing a stable space for the reaction; the sealing support block and the plugging component work together to achieve radial sealing, reducing heat loss; the conductive rod and the through rod form a conductive circuit, directly converting the reaction heat energy into electrical energy, eliminating the intermediate medium transfer link. This structure improves energy recovery efficiency, is suitable for medium and high pressure reaction systems, and enhances conductivity stability through tapered connections, ensuring efficient conversion of chemical energy and reducing energy waste.

[0023] like Figures 1-3 As shown, it illustrates a chemical energy direct recovery power generation heat-end reactor in a medium-high pressure reaction system according to an embodiment of this disclosure, comprising: A pair of high-pressure reactor shells 1, a spliced ​​shell 2, and a pair of conductive rods 3 are provided. The conductive rods 3 are all disposed inside the high-pressure reactor shells 1 and the spliced ​​shells 2. The high-pressure reactor shells 1 and the spliced ​​shells 2 are fixedly connected by screws and bolts. A flow-blocking assembly 5 is disposed at both ends of the high-pressure reactor shell 1; A filler support assembly 4 is disposed between the conductive rods 3; The packing support assembly 4 includes a pair of cylindrical bodies 4-1, each cylindrical body 4-1 being disposed inside the outer shell 1 of the high-pressure reactor. Each cylindrical body 4-1 is fitted with a sealing member 4-2. Both ends of the sealing member 4-2 are fitted with sealing support blocks 4-3. The pair of sealing support blocks 4-3 are respectively supported at both ends of the cylindrical bodies 4-1. Each sealing support block 4-3 has an insertion hole 4-4 on its surface. The conductive rod 3 is inserted into the insertion hole 4-4 of one of the sealing support blocks 4-3. A conductive rod 4-5 is inserted and connected between the insertion holes 4-4 of the opposite sealing support blocks 4-3 of the pair of cylindrical bodies 4-1.

[0024] In some examples, to provide a stable space for exothermic chemical reactions through sealed isolation and conductive connection, a packing support assembly 4 is designed. A pair of cylinders 4-1 are coaxially distributed within the high-pressure reactor shell 1. An externally fitted sealing element 4-2, made of high-temperature resistant elastic material, fits tightly against the outer wall of the cylinder 4-1, forming a radial seal to prevent leakage of the reaction medium. The sealing support blocks 4-3 at both ends of the sealing element 4-2 are annular structures made of heat-insulating material, inserted into the end grooves of the sealing element 4-2, supporting both ends of the cylinder 4-1, providing axial restraint for the sealing element 4-2, and reducing heat exchange between the cylinder 4-1 and the outside. The insertion holes 4-4 on the surface of the sealing support blocks 4-3 are axially oriented, and a conductive rod 3 is inserted into one of the insertion holes 4-4 of the sealing support block 4-3, serving a positioning and guiding function to ensure accurate installation of the cylinder 4-1. A conductive rod 4-5, made of conductive material, is inserted between the insertion holes 4-4 of the opposing sealing support blocks 4-3 of a pair of cylinders 4-1. Both ends of the rod are tightly fitted into the insertion holes 4-4, achieving electrical connection between the two cylinders 4-1 without affecting the flow of the reaction medium. The interior of the cylinder 4-1 is hollow, used to hold the packing material that generates an exothermic chemical reaction. The packing material contacts the conductive rod 3 and the conductive rod 4-5, converting the heat energy generated by the reaction into electrical energy.

[0025] During operation, the packing material is loaded into the cylinder 4-1. The sealing support block 4-3 and the plugging component 4-2 work together to achieve a sealed installation of the cylinder 4-1, ensuring the reaction takes place within a closed space. The heat generated by the reaction raises the temperature of the packing material, forming a conductive circuit through the conductive rod 3 and the connecting rod 4-5, thus converting chemical energy into electrical energy. The combination of the plugging component 4-2 and the sealing support block 4-3 prevents leakage of the high-temperature, high-pressure reaction medium, ensuring the safe and stable progress of the reaction. The elastic seal of the plugging component 4-2 adapts to the deformation of the cylinder 4-1 under high-pressure conditions, ensuring reliable sealing. The heat-insulating sealing support block 4-3 reduces heat loss and improves energy recovery efficiency. The connecting rod 4-5 provides electrical connection without obstructing the flow of the medium, ensuring smooth reaction. The positioning function of the conductive rod 3 ensures the coaxiality of the cylinder 4-1 installation, avoiding seal failure or poor conductivity due to misalignment. This assembly provides a sealed and stable space for exothermic chemical reactions while simultaneously achieving conductive connections for energy conversion, meeting the needs of medium- and high-pressure reaction systems.

[0026] like Figures 1-3As shown in the figure, the sealing and flow assembly 5 proposed in this embodiment includes a high-pressure reactor inlet pipe 5-1 and a high-pressure reactor outlet pipe 5-2. The high-pressure reactor inlet pipe 5-1 and the high-pressure reactor outlet pipe 5-2 are respectively connected to both ends of the outer wall of the high-pressure reactor shell 1. Both ends of the outer wall of the high-pressure reactor shell 1 are provided with an outwardly protruding layer 5-3. Both ends of the high-pressure reactor shell 1 are fitted with sealing sleeves 5-4. The conductive rod 3 passes through the sealing sleeve 5-4. A connecting sleeve 5-5 is fitted outside the sealing sleeve 5-4. The connecting sleeve 5-5 is connected to the outer wall of the outwardly protruding layer 5-3 by threaded connection. The sealing sleeve 5-4 has a T-shaped cross-section and one end passes through the connecting sleeve 5-5. One end of the conductive rod 3 is equipped with a sealing sleeve 5-4 nozzle. One end of the conductive rod 3 is connected to a fastening bolt 5-7 by threaded screwing. One end of the conductive rod 3 is provided with a terminal post 5-8.

[0027] In some examples, to achieve sealing and media flow of the high-pressure reactor shell 1, the inlet and outlet pipes at both ends of the outer wall of the high-pressure reactor shell 1 are connected by welding to form media inlet and outlet channels. Valves are installed on both the inlet and outlet pipes to control the media flow rate. The outer convex layer 5-3 on both ends of the outer wall of the high-pressure reactor shell 1 is integrally formed with the cylinder 4-1, and the outer wall is threaded. The sealing sleeve 5-4 is made of high-temperature and high-pressure resistant composite material with a T-shaped cross-section, and is fitted onto the end of the cylinder 4-1. One end passes through the connecting sleeve 5-5 and fits tightly against the end face of the cylinder 4-1, forming the first seal. The connecting sleeve 5-5 is threadedly connected to the outer wall of the outer convex layer 5-3. When tightened, it compresses the sealing sleeve 5-4, causing it to deform and enhancing the sealing effect. The conductive rod 3 passes through the through hole in the center of the sealing sleeve 5-4 and is sealed with the sealing sleeve 5-4 by an O-ring. The nozzle of the sealing sleeve 5-4 at one end has a conical structure and fits tightly against the surface of the conductive rod 3, forming the second seal to prevent media leakage along the surface of the conductive rod 3. One end of the conductive rod 3 is tightened with a threaded fastening bolt 5-7 to press the sealing sleeve 5-4 to ensure a reliable seal. The terminal 5-8 at the end is used to connect to an external circuit to conduct the generated electrical energy.

[0028] During operation, the reaction medium enters the high-pressure reactor shell 1 through the feed pipe, participates in the reaction, and is discharged from the discharge pipe. The threaded engagement between the connecting sleeve 5-5 and the outer protruding layer 5-3 ensures that the sealing sleeve 5-4 tightly fits the end of the cylinder 4-1, achieving sealing of the cylinder 4-1. The multi-layer sealing structure of the sealing sleeve 5-4 and its nozzle prevents leakage of the high-pressure medium. The conductive rod 3 conducts electrical energy while maintaining the sealing of the cylinder 4-1 through the sealing structure. The multi-layer sealing structure adapts to the high-pressure environment, ensuring reliable sealing and preventing safety hazards caused by medium leakage. The directional flow guidance of the feed pipe and discharge pipe ensures that the medium flows along a preset path, guaranteeing a complete reaction. The threaded connection of the connecting sleeve 5-5 facilitates disassembly and maintenance, and the sealing pressure can be adjusted by tightening. The terminal block 5-8 facilitates electrical energy output and chemical energy recovery. This component, through the combination of multi-layer sealing and directional flow guidance, achieves reliable sealing of the high-pressure reactor shell 1 and medium flow, ensuring the stable operation of the reaction system.

[0029] For example, such as Figure 3 As shown, one end of the conductive rod 3 and both ends of the conductive rods 4-5 are tapered structures.

[0030] In some examples, both ends of the conductive rod 3 and the conductive rods 4-5 are tapered, which enhances the tightness of the connection. The tapered structure automatically aligns the conductive rod 3 and conductive rods 4-5 during insertion, reducing contact gaps, improving conductivity, and ensuring the smooth transfer of electrical energy converted from chemical energy. Simultaneously, this structure enhances connection stability under high-pressure environments through the compression of the contact surfaces, preventing poor contact due to vibration or pressure changes and ensuring the continuous reliability of the conductive circuit.

[0031] For example, such as Figure 2 As shown, the cylinder 4-1 is a cylindrical structure made of ceramic material. The cylinder 4-1 can be filled with material, which can be a sintered material or a loosely packed granular material.

[0032] In some examples, the cylindrical ceramic cylinder 4-1 exhibits high-temperature and corrosion resistance, making it suitable for medium- and high-pressure reaction environments. The shaped sintered material or loosely packed particulate material filling the cylinder 4-1 provides sufficient reaction contact area, promoting the full conduct of exothermic chemical reactions. The ceramic cylinder 4-1 does not participate in the reaction and is insulating, isolating the reaction medium from the external structure while protecting the internal packing, ensuring reaction stability, and improving energy recovery efficiency.

[0033] In practical use: The ceramic cylinder 4-1 is installed inside the high-pressure reactor shell 1. The sealing component 4-2 is fitted onto the outside of the cylinder 4-1, and both ends are inserted into the sealing support blocks 4-3 to form a seal. The conductive rod 3 is inserted into the insertion hole 4-4 of one side of the sealing support block 4-3, and the conductive rod 4-5 connects the insertion holes 4-4 of the sealing support blocks 4-3 on both sides to form a conductive circuit. The high-pressure reactor shell 1 and the spliced ​​shell 2 are fixed by screws and bolts. Tightening the connecting sleeve 5-5 compresses the T-shaped sealing sleeve 5-4, and the high-pressure seal is achieved by cooperating with the nozzle of the sealing sleeve 5-4. The reaction medium enters the cylinder 4-1 through the feed pipe, reacts with the internal filling material to release heat energy, and converts the chemical energy into electrical energy through the circuit formed by the conductive rod 3 and the conductive rod 4-5. The electrical energy is discharged through the terminal 5-8, and the reacted medium is discharged from the discharge pipe. The medium and high pressure environment is maintained throughout the process by the multi-layer sealing structure.
