Description

Technical Field

[0001] This utility model relates to the field of reactor jacket technology, and in particular to a reactor jacket based on an inorganic heat-conducting medium. Background Technology

[0002] The reactor is equipped with an outer jacket because many chemical reactions are highly sensitive to temperature. Rapid heat conduction means that the reactor can respond to temperature changes more quickly. When the reaction is exothermic or endothermic, it can be rapidly cooled through the jacket / coil to stabilize the temperature at the set value, thereby ensuring product quality and reaction safety.

[0003] Existing jackets generally use coils, and heat exchange takes place directly in the water pipes. As the water flows, it continuously exchanges and carries away heat. However, the heat exchange efficiency decreases as the water heats up in the later stages, and water resources are wasted significantly during cooling. Summary of the Invention

[0004] To address the aforementioned problems, this utility model aims to solve the problems described above. One objective of this utility model is to provide a reactor jacket based on an inorganic heat-conducting medium, which centrally arranges the heat exchange areas to quickly remove heat from the reactor, resulting in higher heat exchange efficiency.

[0005] The present invention adopts the following solution: a reactor jacket based on an inorganic heat-conducting medium, comprising a plurality of heat-conducting plates, wherein the plurality of heat-conducting plates are arranged in series around the outer wall of the reactor, the heat-conducting plates are provided with an inorganic heat-conducting medium, and a heat exchange section is provided at the top of the heat-conducting plates. When the heat-conducting plates are heated, the inorganic heat-conducting medium vaporizes and carries the heat to the heat exchange section at the top; the heat is uniformly conducted to the top, resulting in a large temperature difference in the heat exchange section and higher heat exchange efficiency.

[0006] The heat-conducting plates are arranged vertically, and a heat exchange shell is provided on the outside of the heat exchange section. The heat exchange sections of several heat-conducting plates are inserted into the heat exchange shell, and a cooling device is provided in the heat exchange shell to remove the heat from the heat exchange section. This centralized heat exchange with the heat-conducting plates avoids repeated heat exchange by the water flow, thus reducing efficiency and improving water resource utilization.

[0007] To adapt to different reactors and achieve quick and convenient installation, the heat-conducting plate is designed to conform to the outer contour of the reactor wall. A connector is located on the outer side of the heat-conducting plate, with a connecting ball at one end and a ball groove at the other. During installation, the connecting ball is inserted into the ball groove of another heat-conducting plate. Both the connecting ball and the ball groove have through holes on their sides, which are secured by inserting pins into the through holes during installation.

[0008] Furthermore, a slot is provided on the side of the heat exchange shell near the reactor. During installation, the heat-conducting plate passes through the slot and is inserted into the heat exchange shell. The heat exchange shell has a heat exchange cavity inside, and a spray pipe is provided at the top of the heat exchange cavity. The spray pipe has several spray holes to spray water onto the heat-conducting plate.

[0009] A preferred technical solution for heat exchange is that a reflux trough is provided at the bottom of the heat exchange cavity, a water inlet pipe is provided at the top of the heat exchange shell and the water inlet pipe is connected to the spray pipe, and a reflux pipe is provided at the bottom of the heat exchange shell and the reflux pipe is connected to the reflux trough.

[0010] A preferred technical solution for installing the heat exchange shell is that a mounting bracket is provided on the outside of the heat exchange shell, one end of the mounting bracket is fixedly connected to the heat exchange shell, and the other end is fixedly connected to the outer wall of the reactor.

[0011] To better adapt to different reactors, an obstacle avoidance connecting rod is also included. When there is an obstacle on the outer wall of the reactor, the heat conduction plate is not installed at that position. The two adjacent heat conduction plates are fixed together by the obstacle avoidance connecting rod. The two ends of the obstacle avoidance connecting rod are respectively provided with a connecting ball head and a ball head groove.

[0012] A preferred technical solution is that the outer wall of the heat exchange section is provided with a number of heat dissipation fins.

[0013] Compared with the prior art, the reactor jacket based on inorganic heat-conducting medium of this utility model has the following technical effects: 1. This application relates to a reactor jacket based on an inorganic heat-conducting medium, comprising a plurality of heat-conducting plates arranged in series around the outer wall of the reactor. Each heat-conducting plate contains an inorganic heat-conducting medium, and a heat exchange section is located at the top of each plate. When heated, the inorganic heat-conducting medium vaporizes, carrying the heat to the top heat exchange section. This unified heat transfer to the top results in a large temperature difference in the heat exchange section and higher heat exchange efficiency. The inorganic heat-conducting medium enables rapid heat removal and higher heat dissipation efficiency.

[0014] The heat-conducting plates are arranged vertically, and a heat exchange shell is provided on the outside of the heat exchange section. The heat exchange sections of several heat-conducting plates are inserted into the heat exchange shell, and a cooling device is provided in the heat exchange shell to remove the heat from the heat exchange section. Centralized heat exchange on the heat-conducting plates avoids repeated heat exchange by the water flow, thus reducing efficiency and improving water resource utilization. Unified heat exchange in the heat exchange section results in a smaller heat exchange space but a larger temperature difference, which facilitates rapid heat exchange and removal, allowing for rapid heat exchange with a small amount of water.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0019] The jacket of the reactor 1 based on the inorganic heat-conducting medium will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3As shown, a reactor jacket based on an inorganic heat-conducting medium includes several heat-conducting plates 2, which are arranged in series around the outer wall of the reactor 1. The heat-conducting plates 2 contain an inorganic heat-conducting medium, and a heat exchange section 21 is located at the top of each heat-conducting plate 2. When heated, the inorganic heat-conducting medium vaporizes, carrying heat to the heat exchange section 21 at the top. This unified heat transfer to the top results in a large temperature difference in the heat exchange section 21, leading to higher heat exchange efficiency. The heat-conducting plates 2 are made of a metal material with high thermal conductivity, such as aluminum alloy, to ensure rapid heat conduction. Each heat-conducting plate 2 has a sealed cavity filled with an inorganic heat-conducting medium, such as distilled water or liquid metal. These media undergo vaporization phase change upon heating, absorbing a large amount of latent heat. Preferred heat transfer medium: The heat transfer medium is a FUD inorganic superconducting medium, composed of a ternary eutectic salt of Li₂CO₃-K₂CO₃-Cs₂CO₃, with the addition of 0.6 wt% graphene and 0.4 wt% CeO₂. This medium exhibits high thermal conductivity, high stability, and low start-up temperature. Graphene, as a nanofiller, constructs a highly efficient heat conduction network; CeO₂, as a stabilizer, effectively inhibits the decomposition of carbonates at high temperatures, extending the medium's lifespan. The filling volume of 12% of the heat pipe's inner cavity volume is a key parameter verified through precise calculations and experiments. This ratio ensures sufficient liquid film formation for efficient evaporation in the evaporation section, while preventing liquid blockage in the condensation section, which would affect vapor flow and condensation reflux, thus achieving optimal heat transfer power and start-up characteristics. Utilizing phase change heat transfer, it achieves millisecond to second-level instantaneous response and extremely high heat transfer efficiency, far exceeding traditional heat conduction.

[0021] When the outer wall of the reactor 1 is heated, the heat-conducting plate 2 absorbs heat, and the internal inorganic heat-conducting medium rapidly vaporizes, generating steam or high-temperature gas. Due to the density difference, this gas naturally rises to the heat exchange section 21 at the top. The outer wall of the heat exchange section 21 is equipped with several heat dissipation fins 211. The heat exchange section 21 is designed with an enlarged surface area to enhance heat exchange. Multiple heat-conducting plates 2 are connected in series and arranged around each other, ensuring that heat is evenly collected from the outer wall of the reactor 1 and concentrated and directed to the top, avoiding heat dispersion. According to thermodynamic principles, the greater the temperature difference between the heat exchange section 21 and the cooling medium, the higher the heat exchange rate. This design maximizes the temperature difference between the top heat exchange section 21 and the cooling system, thereby significantly improving heat exchange efficiency, reducing energy loss, and making the temperature control of the reactor 1 more precise and stable.

[0022] The heat-conducting plates 2 are arranged vertically, and a heat exchange shell 3 is provided on the outside of the heat exchange section 21. The heat exchange sections 21 of several heat-conducting plates 2 are inserted into the heat exchange shell 3, and a cooling device is provided in the heat exchange shell 3 to remove the heat from the heat exchange sections 21. This centralized heat exchange with the heat-conducting plates 2 avoids repeated heat exchange by water flow, thus reducing efficiency and improving water resource utilization. The vertical installation of the heat-conducting plates 2 facilitates the natural circulation of the inorganic heat-conducting medium: after vaporization, it rises to the heat exchange section 21, and after condensation, it flows back to the bottom by gravity, forming a continuous phase change cycle. The heat exchange shell 3 is made of corrosion-resistant materials such as stainless steel, and forms a closed heat exchange cavity 34 inside. After all the heat exchange sections 21 of the heat-conducting plates 2 are inserted into the heat exchange shell 3, the cooling device centrally cools the heat exchange sections 21. Cooling water is evenly sprayed onto the surface of the heat exchange sections 21 through spray pipes 4, absorbs heat, and then flows out, avoiding the temperature rise and efficiency reduction caused by repeated flow of cooling water on the outer wall of the reactor 1 in traditional jacketed systems. This centralized heat exchange design reduces the amount of cooling water used and the number of circulations. According to the principle of energy conservation, centralized heat processing can maximize the utilization rate of the cooling medium, thereby reducing water consumption and operating costs, while improving heat exchange speed and system responsiveness.

[0023] To adapt to different reactors 1 and achieve quick and convenient installation, the heat-conducting plate 2 is designed to conform to the outer contour of the reactor 1. A connector 22 is provided on the outer side of the heat-conducting plate 2. One end of the connector 22 has a connecting ball head 221, and the other end has a ball head groove 222. During installation, the connecting ball head 221 is inserted into the ball head groove 222 of another heat-conducting plate 2. Both the connecting ball head 221 and the ball head groove 222 have through holes 223 on their sides, which are used for fixing during installation by inserting pins into the through holes 223. The heat-conducting plate 2 adopts a flexible design, allowing it to be bent and adjusted according to the curved shape of the outer wall of the reactor 1, ensuring a tight fit and avoiding thermal resistance. The connector 22 is made of high-strength, high-temperature resistant materials such as stainless steel or titanium alloy. The connecting ball head 221 and the ball head groove 222 form a spherical hinge structure, allowing for angle adjustment in multiple directions to accommodate reactors 1 of different diameters and shapes. During installation, the connecting ball joint 221 of the adjacent heat-conducting plate 2 is inserted into the ball joint groove 222, and then locked by a pin through the through hole 223, forming a stable mechanical connection. This ball joint connection mechanism is similar to a universal joint, providing installation flexibility and fault tolerance. It can be quickly assembled without precision tools, reducing installation time and labor costs. At the same time, the tight fit improves heat conduction efficiency, and the pin fixation prevents loosening and displacement during use, ensuring long-term operational reliability.

[0024] Furthermore, a slot 33 is provided on the side of the heat exchange shell 3 near the reactor 1. During installation, the heat-conducting plate 2 passes through the slot 33 and is inserted into the heat exchange shell 3. The heat exchange shell 3 has a heat exchange cavity 34 inside, and a spray pipe 4 is provided at the top of the heat exchange cavity 34. The spray pipe 4 is provided with several spray holes 41 to spray water onto the heat-conducting plate 2. The cooling device can be a spray system or an air-cooled fan; this example uses a spray system. The size of the slot 33 of the heat exchange shell 3 matches the cross-section of the heat exchange part 21 of the heat-conducting plate 2. It is usually sealed with a rubber sealing ring or a flexible gasket to prevent cooling water leakage. During installation, the heat exchange part 21 of the heat-conducting plate 2 is easily inserted into the heat exchange cavity 34 through the slot 33, realizing modular assembly. The heat exchange cavity 34 is a closed space, with a top spray pipe 4 connected to an external water source. The spray pipe 4 has multiple spray holes 41, on which atomizing nozzles can be installed to evenly spray water onto the surface of the heat exchange section 21, forming a water film to maximize the contact area. After absorbing heat, the cooling water's temperature rises and then falls. This design is based on the principle of convection heat transfer; the water film flow enhances the heat exchange rate, while the slotted structure 33 simplifies maintenance and replacement processes, avoids complex disassembly, and improves the system's maintainability and applicability.

[0025] A preferred heat exchange solution involves a return trough 341 at the bottom of the heat exchange cavity 34, a water inlet pipe 31 at the top of the heat exchange shell 3 connected to the spray pipe 4, and a return pipe 32 at the bottom of the heat exchange shell 3 connected to the return trough 341. The return trough 341, located at the bottom of the heat exchange cavity 34, facilitates the collection of used cooling water. The water inlet pipe 31 connects to an external water pump or water supply system, distributing cooling water through the spray pipe 4. The return pipe 32 guides hot water from the return trough 341, which can be connected to a cooling tower or a circulation system for water reuse. This circulation system, based on a closed-loop cooling principle, reduces the amount of fresh water needed, while the design of the return trough 341 prevents corrosion or impurity accumulation caused by water accumulation. Through water circulation, the system maintains stable cooling efficiency, reduces operating costs and environmental impact, and extends equipment lifespan.

[0026] A preferred technical solution for installing the heat exchange shell 3 is that a mounting bracket 35 is provided on the outer side of the heat exchange shell 3. One end of the mounting bracket 35 is fixedly connected to the heat exchange shell 3, and the other end is fixedly connected to the outer wall of the reactor 1. The mounting bracket 35 is made of a rigid material such as carbon steel or aluminum alloy and is fixed to the heat exchange shell 3 and the outer wall of the reactor 1 by welding or bolts. The mounting bracket 35 is designed as an adjustable structure, such as with a sliding groove or hinge, to adapt to different heights and diameters of the reactor 1. When fixing, the matching of thermal expansion coefficients must be considered to avoid stress caused by temperature changes. This installation method ensures the stability of the heat exchange shell 3, prevents displacement caused by vibration or external forces, and maintains the alignment of the heat-conducting plate 2 with the heat exchange shell 3, thereby ensuring the continuity and safety of heat exchange. The rigid support of the mounting bracket 35 also simplifies the overall structure and reduces the frequency of maintenance.

[0027] To better adapt to different reactor vessels 1, a clearance connecting rod is also included. When there is an obstacle on the outer wall of the reactor vessel 1, the heat-conducting plate 2 is not installed at that location, and two adjacent heat-conducting plates 2 are fixed together by the clearance connecting rod. The clearance connecting rod has a connecting ball head 221 and a ball head groove 222 at both ends. The clearance connecting rod uses the same connection mechanism as the heat-conducting plate 2, and its length can be customized according to the size of the obstacle. It is made of lightweight, high-strength metal. When there is a protrusion on the outer wall of the reactor vessel 1, the clearance connecting rod is installed at that location instead of the heat-conducting plate 2. It is connected to the adjacent heat-conducting plate 2 through the connecting ball head 221 and the ball head groove 222, and fixed with a pin. This design maintains the overall structural integrity of the jacket, avoids interruption of heat collection, and ensures installation flexibility. The use of the clearance connecting rod expands the applicability of the jacket, enabling it to adapt to various complex industrial environments and improving the system's versatility and reliability.
