Description

Technical Field

[0001] This application relates to the field of chemical production technology, and in particular to a separate-inlet reactor. Background Technology

[0002] In chemical production, especially in reactions involving flammable materials and oxidizers (such as oxygen), preventing explosions is a critical safety issue that urgently needs to be addressed. Many reactions are prone to explosion within specific concentration ranges, particularly when high concentrations of flammable materials are mixed with oxygen, where the explosion limits are easily exceeded, leading to safety accidents. Therefore, effectively controlling the concentration of reactants to prevent reaching the explosion limits while simultaneously improving reaction efficiency has long been a challenging technical problem for the chemical industry.

[0003] Currently, traditional safety measures typically involve introducing protective gases or adjusting material concentrations to reduce the risk of explosion. While the use of protective gases can effectively dilute reactant concentrations and reduce the likelihood of explosion, it also significantly reduces the reaction rate, decreases product yield, and may even prevent production output from meeting industrial-scale requirements. Furthermore, this method leads to additional energy consumption, as it requires large amounts of protective gas for dilution, increasing equipment operating costs and energy consumption.

[0004] In catalytic oxidation reactions, especially when processing organic materials, the concentration of combustible materials in the reactor must be strictly controlled below 25% of the lower explosive limit. While this control standard reduces the risk of explosion, it necessitates an increase in reactor volume, leading to higher equipment construction and maintenance costs. Furthermore, the increased reactor volume directly results in higher energy consumption, exacerbating energy consumption throughout the production process and consequently impacting economic efficiency.

[0005] Therefore, there is an urgent need for a new reactor design that can ensure safe reaction while avoiding explosions, effectively improve reaction yield, reduce energy consumption, and optimize equipment costs. Utility Model Content

[0006] In order to achieve a safe reaction while avoiding explosions, and to improve reaction yield and reduce energy consumption, this application provides a separate gas inlet reactor.

[0007] This application provides a separate air-inlet type reactor using the following technical solution:

[0008] A separate-inlet reactor includes a reactor body and a catalytic component. The catalytic component is disposed inside the reactor body. The reactor body has a first inlet channel, a second inlet channel, and an outlet channel communicating with its interior. The first inlet channel and the second inlet channel are used to introduce combustible materials and combustion aids, respectively. The first inlet channel and the second inlet channel are independent of each other and respectively lead to different regions of the catalytic component.

[0009] By adopting the above technical solution, this application designs two independent air inlet channels to ensure that the combustion accelerant and combustible materials do not mix directly before contacting the flame-retardant and explosion-proof metal mesh catalyst layer, thereby avoiding the limitations imposed by the explosion limits. Under the premise of safety, the chemical reaction can be carried out within the explosion limits, improving reactor efficiency, reaction conversion rate, and yield. At the same time, this design avoids excessive gas dilution and unnecessary use of protective gas, reducing additional energy consumption, and can also improve the reaction rate and product formation efficiency, achieving higher reaction efficiency with lower energy consumption, effectively reducing energy consumption in the production process. Furthermore, the separate air inlet design optimizes the reactor volume, eliminating the need to excessively increase the reactor size, which not only reduces the cost of equipment construction and maintenance, but also indirectly reduces production costs by improving reaction efficiency and reducing energy consumption.

[0010] In one specific implementation, the catalytic assembly includes a plurality of catalyst layers stacked at intervals.

[0011] By adopting the above technical solution, the stacked design of multiple catalyst layers can provide a larger reaction surface area in a smaller space, thereby improving the reaction rate. Each catalyst layer can participate in the catalytic reaction and is distributed in different catalytic regions to ensure the high efficiency of the reaction, improve reaction efficiency, optimize reaction conditions, enhance reaction safety, and reduce energy consumption and production costs.

[0012] In one specific implementation, the first air intake passage and the second air intake passage respectively enter the spacer region between adjacent catalyst layers from opposite directions.

[0013] By adopting the above technical solution and utilizing the reverse airflow design, the combustion improver and combustible material enter the space between adjacent catalyst layers from opposite directions. They are effectively separated before entering the catalyst layer, and the path of the combustion improver and combustible material inside the reactor is extended, avoiding unnecessary preliminary reactions when the combustion improver and combustible material come into contact with the catalyst too early, thereby further improving the safety and reaction yield of the reaction process.

[0014] In one specific implementation, the catalytic assembly includes a single-layer catalyst layer wound into a hollow cylindrical shape.

[0015] By adopting the above technical solution, a larger reaction surface area can be provided in a limited space through the winding design of the hollow cylindrical structure, so that more reactants can come into contact with the catalyst surface, thereby improving the efficiency and rate of the catalytic reaction.

[0016] In one specific implementation, the first air intake channel opens into the internal cavity of the hollow cylindrical catalyst layer, and the second air intake channel opens into the outer edge region of the hollow cylindrical catalyst layer.

[0017] By adopting the above technical solution and utilizing two different inlet designs, the combustion improver is introduced into the internal cavity of the hollow cylindrical catalyst layer, while the combustible material enters the outer edge area. This ensures that the two gases do not mix before entering the catalyst layer, avoiding premature reaction and potential instability during the reaction process, and further improving the safety and yield of the reaction process.

[0018] In one specific implementation, the catalyst layer is a metal mesh catalyst layer.

[0019] By adopting the above technical solution, the metal mesh catalyst layer, due to its mesh structure, can provide a large surface area for the reactants to contact the catalyst, thereby improving the contact efficiency between the reactants and the catalyst, and thus increasing the acceleration and rate of the reaction.

[0020] In one specific implementation, a cooling pipe is also included, which is located in the catalytic component area and close to the area through which the combustible material is introduced.

[0021] By adopting the above technical solution, when combustible materials come into contact with the catalytic components and combustion aids, there may be a risk of spontaneous combustion due to excessively high reaction temperatures. The cooling pipe, located in the catalytic component area and close to the area where combustible materials are introduced, can cool the intake area, reduce the local temperature, reduce the risk of spontaneous combustion of combustible materials, prevent excessively high temperatures from causing unnecessary thermal reactions, and ensure that the temperature during the reaction process is always within a safe range, thereby further avoiding the risk of explosion and improving the safety and stability of the reaction process.

[0022] In one specific implementation, the second air intake passage is provided with a heating component for preheating the combustion aid.

[0023] By adopting the above technical solution and utilizing the design of the heating component, the temperature of the combustion improver can be increased, making it easier for it to react with combustible materials after entering the catalytic component. The heated combustion improver can provide higher thermal energy, promote the catalytic reaction, and thus improve the overall reaction efficiency.

[0024] In one specific implementation, the first intake passage and the second intake passage are provided with flow control valves.

[0025] By adopting the above technical solution and utilizing the design of the flow control valve, the gas flow rate entering the system can be adjusted, thereby achieving control of the mixed gas of the combustion accelerant and combustible material. By adjusting the flow rate, the gas supply can be adjusted according to the needs of different reaction stages to ensure that the gas ratio in the reaction process meets the optimal reaction conditions.

[0026] In one specific implementation, the system further includes a pressure sensor, a control unit, and a pressure relief valve. The control unit is used to receive the pressure signal detected by the pressure sensor and control the opening and closing state of the pressure relief valve according to a preset pressure threshold.

[0027] By adopting the above technical solution, when the internal pressure of the reactor exceeds the predetermined safety threshold, the pressure sensor will immediately detect it and transmit the signal to the control unit. The control unit will then control the pressure relief valve to open and release the excess gas, thereby preventing the reactor from exploding or other safety accidents caused by high pressure.

[0028] In summary, the beneficial technical effects of this application are as follows: By designing two independent air inlet channels, this application ensures that the combustion accelerant and combustible materials do not directly mix before contacting the flame-retardant and explosion-proof metal mesh catalyst layer, thereby circumventing the limitations imposed by the explosion limits. Under the premise of safety, the chemical reaction can proceed within the explosion limits, improving reactor efficiency, reaction conversion rate, and yield. Simultaneously, the layered design of multiple catalyst layers and the hollow cylindrical structure optimize the surface area and utilization rate of the catalyst, improving reaction efficiency, reducing energy consumption, and optimizing the reactor volume, thus reducing equipment construction and maintenance costs.

[0029] In addition, the solution effectively controls the reaction temperature and gas flow rate through the coordinated design of cooling pipes, heating components and flow control valves, further improving the stability and controllability of the reaction and avoiding safety accidents caused by high temperature and high pressure. The overall design improves the reaction rate and product generation efficiency, optimizes energy consumption and reduces production costs. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a separate-inlet reactor, including but not limited to catalytic oxidation reactions (including decomposition and synthesis reactions) of combustible materials and combustion accelerants. In this embodiment, both the combustible material and the combustion accelerant are gases. The decomposition reaction can be the decomposition reaction of ethylene oxide (combustible material) and air (combustible accelerant), which decomposes into water and carbon dioxide after the reaction. The synthesis reaction can be the synthesis reaction of ethylene (combustible material) and oxidant (combustible accelerant), which synthesizes ethylene oxide after the reaction.

[0037] Example 1

[0038] Reference Figure 1 The separate air intake reactor includes a reactor body 1 and a catalyst component 2. The catalyst component 2 is located inside the reactor body 1. The reactor body 1 is provided with a first air intake channel 3, a second air intake channel 4 and an air outlet channel 5 that communicate with its interior. In this embodiment, the first air intake channel 3 and the second air intake channel 4 are horizontally arranged on the side of the reactor body 1. The first air intake channel 3 and the second air intake channel 4 can be arranged on the same side or on different sides. The air outlet channel 5 is vertically arranged at the bottom of the reactor body 1.

[0039] The first air inlet channel 3 is used to introduce combustible materials into the reactor body 1, and the second air inlet channel 4 is used to introduce combustion aid into the reactor body 1. The first air inlet channel 3 and the second air inlet channel 4 are independent of each other and are respectively introduced into different areas of the catalyst component 2.

[0040] In this embodiment, the second air intake channel 4 is equipped with a heating component. The design of the heating component can increase the temperature of the combustion aid, making it easier for it to react with the combustible material after entering the catalytic component 2. The heated combustion aid can provide higher heat energy, promote the catalytic reaction, and thus improve the overall reaction efficiency.

[0041] During operation, the combustion aid and combustible material are introduced into the reactor body 1 through the first air inlet channel 3 and the second air inlet channel 4, respectively. The combustion aid is heated by the heating component and enters the reactor body 1 after the temperature is increased. The combustion aid and combustible material are introduced into different areas inside the catalytic component 2 and undergo catalytic oxidation reaction inside the catalytic component 2. The products after the reaction are completed are discharged through the gas outlet channel 5.

[0042] In this process, by designing two air intake channels to work independently, it is ensured that the combustion improver and combustible material will not mix directly when entering the reactor. Instead, they are guided to different catalytic zones of the catalytic component 2 through different channels, avoiding direct over-mixing of the combustion improver and combustible material. This controls the concentration range of the reaction, avoids the risk of explosion caused by direct over-mixing, and improves the safety of the reaction process.

[0043] In this embodiment, the catalytic component 2 includes a plurality of catalyst layers 6 stacked at intervals, with adjacent catalyst layers 6 forming a spacer region 8. The catalyst layers 6 are fixed on the inner wall of the reactor body 1. The catalyst layers 6 can be arranged horizontally or vertically. The plurality of catalyst layers 6 can be evenly distributed along the height direction, width direction or length direction of the reactor body 1. In this embodiment, the plurality of catalyst layers 6 are arranged horizontally and stacked at intervals along the height direction of the reactor body 1.

[0044] By using a stacked design of multiple catalyst layers 6, a larger reaction surface area can be provided in a smaller space. Each catalyst layer 6 can participate in the catalytic reaction, ensuring the high efficiency of the reaction, thereby improving reaction efficiency, optimizing reaction conditions, enhancing reaction safety, reducing energy consumption and production costs, and effectively improving catalyst utilization, ensuring the controllability and economy of the reaction process.

[0045] In this embodiment, the first air inlet channel 3 and the second air inlet channel 4 are respectively introduced into the spacer region 8 between adjacent catalyst layers 6 from opposite directions. That is, the first air inlet channel 3 and the second air inlet channel 4 are respectively located on opposite sides of the reactor body 1. The combustible material and the combustion aid are introduced into the reactor body 1 from two opposite directions. In this embodiment, the first air inlet channel 3 and the second air inlet channel 4 can be set as one or more, and can be designed according to actual needs.

[0046] With the reverse airflow design, the combustion aid and combustible material enter the spacer region 8 between adjacent catalyst layers 6 from opposite directions. They are effectively separated before entering the catalyst layer 6. The path of the combustion aid and combustible material inside the reactor is extended, avoiding unnecessary initial reactions when the combustion aid and combustible material come into contact with the catalyst too early, thereby further improving the safety and reaction yield of the reaction process.

[0047] Catalyst layer 6 is a metal mesh catalyst layer. In this embodiment, the metal mesh catalyst layer includes a metal mesh substrate and a catalyst film disposed on the metal mesh substrate. Utilizing the mesh structure of the metal mesh substrate, it can provide a large surface area for the reactants to contact the catalyst layer, thereby improving the contact efficiency between the reactants and the catalyst, thus increasing the acceleration and reaction rate of the reaction. Furthermore, the mesh structure can provide better fluid channels, reduce fluid resistance, and enable the reactants to be uniformly distributed on the catalyst surface, further improving the reaction efficiency.

[0048] The implementation principle of Example 1 is as follows: During operation, the combustion aid enters the reactor through the first air inlet channel 3 and is heated by the heating component. After the temperature is increased, it enters a certain area of ​​the catalytic component 2. The combustible material enters the reactor through the second air inlet channel 4 and is introduced into another area of ​​the catalytic component 2. The two gases enter the interval area 8 between the catalyst layers 6 respectively. The catalyst layers 6, which are designed with stacking, provide a larger reaction surface area to ensure that the combustion aid and combustible material undergo a highly efficient catalytic oxidation reaction under the action of the catalyst. The products after the reaction are discharged through the gas outlet channel 5.

[0049] This application effectively separates the entry paths of the combustion accelerator and combustible materials through an independently designed air intake channel, ensuring that the combustion accelerator and combustible materials do not directly mix before contacting the flame-retardant and explosion-proof metal mesh catalyst layer 6, thereby controlling the reaction concentration range, reducing the risk of explosion, and improving reaction safety. At the same time, the reverse airflow design can extend the path of the reactants in the catalytic region, improve reaction efficiency and reduce energy consumption, and the heating component can increase the temperature of the combustion accelerator, promote the reaction rate, and further improve reaction efficiency.

[0050] Furthermore, the stacked catalyst layer 6 increases the reaction surface area, improves catalyst utilization, optimizes reaction conditions, and reduces production costs. The metal mesh catalyst layer 6 enhances the reaction rate and product formation efficiency by optimizing surface contact efficiency and fluid channels. This design not only improves the efficiency, safety, and controllability of the reaction process but also reduces energy consumption and production costs, resulting in significant economic and environmental benefits.

[0051] Example 2

[0052] Reference Figure 2 Based on Embodiment 1, this embodiment also includes a cooling pipe 7. The cooling pipe 7 is located in the area of ​​the catalyst component 2 and is set close to the area where the combustible material is introduced. In this embodiment, there are multiple cooling pipes 7, which are set in the interval area 8 between adjacent catalyst layers. The cooling pipes 7 and the interval area 8 are set in a one-to-one correspondence. The cooling pipes 7 are all designed close to the first air intake channel 3, that is, the cooling pipes 7 are located on the side of the interval area 8 close to the side where the combustible material is introduced.

[0053] The implementation principle of Example 2 is as follows: a cooling pipe 7 is added to the catalytic component 2 region. The cooling pipe 7 is located in the interval region 8 between adjacent catalyst layers, especially in the region near the introduction of combustible material. The setting of the cooling pipe 7 can effectively reduce the local temperature in the combustible material inlet region, reduce the risk of spontaneous combustion of combustible material, and prevent unnecessary thermal reactions caused by excessive temperature. Through the function of the cooling pipe 7, the temperature during the reaction process is kept within a safe range, thereby improving the safety and stability of the reactor, further avoiding the risk of explosion, and ensuring that the catalytic reaction proceeds efficiently under optimized conditions.

[0054] Example 3

[0055] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the catalyst assembly 2 includes a single-layer catalyst layer 6 wound into a hollow cylindrical shape. In this embodiment, the catalyst layer 6 wound into a hollow cylindrical shape is horizontally arranged inside the reactor body 1 and fixed on the inner wall of the reactor body 1.

[0056] The catalyst layer 6 is formed into a hollow cylindrical structure through a winding design, which can provide a larger reaction surface area in a limited space, allowing more reactants to come into contact with the catalyst surface, thereby improving the efficiency and rate of the catalytic reaction. At the same time, the hollow cylindrical catalyst layer 6 can effectively utilize space, increasing the effective utilization rate of the catalyst within the same volume, thereby reducing catalyst consumption and achieving higher output with lower energy consumption, thus reducing energy consumption and catalyst usage costs in the production process.

[0057] In this embodiment, the first air intake channel 3 and the second air intake channel 4 are arranged on the same side. The first air intake channel 3 enters the internal cavity 9 of the hollow cylindrical catalyst layer 6, and the second air intake channel 4 enters the outer edge region 10 of the hollow cylindrical catalyst layer 6. The combustible material is introduced into the internal cavity 9 of the hollow cylindrical catalyst layer 6, and the combustion aid is introduced into the outer edge region 10 of the hollow cylindrical catalyst layer 6. The outer edge region 10 is an annular space between the outer surface of the hollow cylindrical catalyst layer 6 and the inner wall of the reactor body 1.

[0058] By employing two different inlet designs—one internal and one external—the combustion improver is introduced into the internal cavity 9 of the hollow cylindrical catalyst layer 6, while the combustible material enters the outer edge region 10. This ensures that the two gases do not mix before entering the catalyst layer 6, avoiding premature reaction and potential instability during the reaction process. Furthermore, the introduction of different gases into the internal cavity 9 and the outer edge region 10 facilitates gradual and uniform mixing within the catalyst layer 6, ensuring the continuous stability and efficiency of the reaction. This further enhances the safety and yield of the reaction process.

[0059] The implementation principle of Example 3 is as follows: During operation, the combustion aid enters the internal cavity 9 of the catalyst layer 6 through the first air inlet channel 3, while the combustible material enters the outer edge region 10 of the catalyst layer 6 through the second air inlet channel 4. The two do not mix directly before entering the catalyst layer 6, thereby avoiding premature reaction and instability. The hollow structure of the catalyst layer 6 provides a larger reaction surface area, ensuring that the reactants and catalyst are in full contact, improving reaction efficiency and catalyst utilization. After the catalytic reaction is completed, the product is discharged through the air outlet channel 5. This design not only improves the safety and efficiency of the reaction, but also reduces energy consumption and catalyst usage costs, and optimizes the reaction process.

[0060] Example 4

[0061] Reference Figure 4 Based on Example 3, this embodiment also includes a cooling pipe 7. The cooling pipe 7 is located in the area of ​​the catalyst component 2 and is set close to the area where combustible materials are introduced. In this embodiment, the cooling pipe 7 is a single pipe, located in the internal cavity 9 of the hollow cylindrical catalyst layer 6. The cooling pipe 7 is located at the center of the hollow cylindrical catalyst layer 6 and is arranged along the axial direction of the hollow cylindrical catalyst layer 6.

[0062] During operation, combustible materials enter the internal cavity 9 of the hollow cylindrical catalyst layer 6 through the first air inlet channel 3. At this time, the cooling pipe 7 inside the internal cavity 9 of the hollow cylindrical catalyst layer 6 can cool down the incoming combustible materials, preventing unnecessary thermal reactions caused by excessive temperature during the reaction process. By effectively reducing the local temperature, the cooling pipe 7 ensures that the temperature during the reaction process is maintained within a safe range, thereby improving the safety and stability of the reactor and further avoiding the risk of explosion. After the catalytic reaction is completed, the reaction products are discharged through the air outlet channel 5. The entire design helps to improve reaction efficiency, reduce energy consumption, and ensure the safety and controllability of the reaction process.

[0063] Example 5

[0064] Based on any one of embodiments 1-4, the second air intake channel 4 is provided with a heating component (not shown in the figure) for preheating the combustion aid. In this embodiment, the heating component can be, but is not limited to, an electric heater (such as an electric heating tube or an electric heating strip). The electric heater is usually composed of an electric heating tube or an electric heating wire, which can be directly installed in the second air intake channel 4 to form thermal radiation or convection heating. The electric heating strip can be wrapped around the outside of the air intake pipe to quickly heat the airflow.

[0065] During operation, the heating component heats the combustion aid, raising its temperature before it enters the reactor body 1, thereby increasing the reaction rate and catalytic efficiency. After entering the catalytic component 2, the heated combustion aid reacts with the combustible material in different catalytic zones. Heating the combustion aid provides higher thermal energy, promotes the catalytic reaction, improves overall reaction efficiency, optimizes reaction conditions, ensures the stability and safety of the reaction process, and reduces energy consumption while increasing reaction yield.

[0066] Example 6

[0067] Based on any one of embodiments 1-4, this embodiment is provided with a flow control valve in the first air intake channel 3 and the second air intake channel 4.

[0068] By designing a flow control valve, the gas flow rate entering the system can be adjusted to control the mixed gas of the combustion accelerant and combustible material. This allows for adjustments to the gas supply based on the needs of different reaction stages, ensuring that the gas ratio meets the optimal reaction conditions. Furthermore, dynamic adjustments can be made according to the actual needs of the reaction to prevent the reaction from becoming unstable due to excessive or insufficient gas flow, thus maintaining stable temperature and pressure within the reactor and improving the controllability and safety of the reaction.

[0069] Example 7

[0070] Based on any one of embodiments 1-4, this embodiment further includes a pressure sensor, a control unit, and a pressure relief valve (not shown in the figure). In this embodiment, the pressure sensor is located inside the reactor body 1, and the pressure relief valve can be located on the gas outlet channel 5 or at other locations on the reactor body 1. The pressure sensor, control unit, and pressure relief valve are electrically connected. The control unit is used to receive the pressure signal detected by the pressure sensor and control the opening and closing state of the pressure relief valve according to a preset pressure threshold.

[0071] During operation, when the internal pressure of the reactor exceeds the predetermined safety threshold, the pressure sensor will immediately detect it and transmit the signal to the control unit. The control unit will then control the pressure relief valve to open and release the excess gas, thereby preventing the reactor from exploding or causing other safety accidents due to high pressure. This improves the safety, stability, and reliability of the reactor and reduces the risk of manual operation.

[0072] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
