Description

Technical Field

[0001] This application relates to the field of reactor technology, and in particular to a novel high-temperature and high-pressure internal combustion heating reactor device. Background Technology

[0002] A reaction vessel, also known as a reaction tank or pressure vessel, is a closed container that can achieve heating, evaporation, cooling, and mixing functions through structural design and parameter configuration, and complete multiphase reactions such as gas-liquid, liquid-liquid, and gas-liquid-solid reactions. It is mainly used in processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation, and is widely used in petroleum, chemical, rubber, pesticide, pharmaceutical, food, coating, and biomedical fields. Common materials include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and composite materials.

[0003] Especially in the chemical industry, when processing mineral powders, it is necessary to first mix powders and granules, then add them into a reactor for reaction processing. After the reaction is completed, extraction, separation, and transportation are performed. During this process, the reactor generates high temperature and high pressure during use, which means that after the reaction is completed, the material inside the reactor must be allowed to cool down to room temperature before the next reaction can begin. This reduces the efficiency of the reactor and makes continuous reaction impossible. Furthermore, for some high-pressure reactions, conventional reactors cannot meet the requirements for long-term operation and are prone to damage due to the inability to withstand high pressure, thus reducing the service life of the reactor. Therefore, a new type of high-temperature and high-pressure internal combustion heating reactor device is proposed. Summary of the Invention

[0004] This application proposes a novel high-temperature and high-pressure internal combustion heating reactor device, which has the advantages of enabling continuous reaction in the reactor, ensuring thorough reaction and extraction of reactants, and being resistant to high temperature and high pressure, thereby solving technical problems such as the inability of reactors to conduct continuous reactions.

[0005] To achieve the above objectives, this application adopts the following technical solution: a novel high-temperature and high-pressure internal combustion heating reactor device, comprising a support leg, a bracket, and a reactor, characterized in that: a bracket for support is fixedly connected to the top of the support leg; a reactor for reaction processing is fixedly installed on the inner side wall of the bracket; a sealing cover for sealing is fixedly installed on the top of the reactor by bolts; an outlet pipe for discharging high-temperature gas is fixedly installed in the middle of the sealing cover; a high-pressure pump inlet pipe for filling materials is fixedly connected to the bottom surface of the reactor; a cooling device is provided at the end of the outlet pipe away from the sealing cover; an extraction and separation device is provided at the bottom of the reactor; a filtration device is provided inside the reactor and the extraction and separation device; and a heat-insulating and high-pressure resistant device is provided inside the reactor.

[0006] Furthermore, the cooling device includes a liquid nitrogen cooler, which is fixedly connected to the end of the outlet pipe away from the sealing cover via a connecting pipe. The output end of the liquid nitrogen cooler is fixedly connected to a water cooler for cooling via a connecting pipe, and the output end of the water cooler is fixedly connected to a back pressure valve for adjusting pressure via a connecting pipe.

[0007] Furthermore, the output end of the back pressure valve is fixedly connected to a collection box, and the output end of the collection box is fixedly connected to a cold liquid outlet for discharging liquid.

[0008] Furthermore, the extraction and separation device includes a drain pipe for discharging liquid, which is fixedly connected to the center of the bottom surface of the reactor. Inside the reactor, at a location on the drain pipe, a filter sleeve for solid-liquid separation is fixedly connected. At the bottom of the reactor, on the side of the drain pipe, a solid material discharge pipe for discharging solid material is fixedly connected. An electric valve for controlling the discharge is fixedly installed on the solid material discharge pipe.

[0009] Furthermore, the extraction and separation device also includes a collection tank for collecting solid materials. A water inlet pipe for adding water is fixedly connected to the bottom of the collection tank, and a liquid discharge pipe for discharging liquid is fixedly connected to the middle of the bottom surface of the collection tank. A filter sleeve for solid-liquid separation is fixedly connected inside the collection tank at the location of the liquid discharge pipe.

[0010] Furthermore, a solid material discharge pipe for discharging solid material is fixedly connected to the bottom surface of the collection tank on the side of the discharge pipe two. An electric valve for controlling the discharge is fixedly installed on the solid material discharge pipe two. An exhaust pipe for discharging gas is fixedly connected to the top surface of the collection tank.

[0011] Furthermore, the heat-insulating and high-pressure-resistant device includes an inner tank, which is fixedly connected to the inner wall of the reactor.

[0012] This application provides a novel high-temperature and high-pressure internal combustion heating reactor device. Through the design of a liquid nitrogen cooler, a water cooler, a back pressure valve, and a water jacket, during normal operation, the high-temperature gas generated inside the reactor rises to the top. At this point, the water jacket cools any unreacted substances, causing them to fall back into the reaction area, ensuring complete reaction. After the reaction is complete, the high-temperature gas generated inside the reactor enters the liquid nitrogen cooler through an outlet pipe to form a cold liquid. This cold liquid is then discharged from the outlet after pressure control by the back pressure valve. This structure allows for rapid cooling after the reaction is complete, enabling continuous reaction and significantly improving the reactor's efficiency.

[0013] By designing a drain pipe, a filter sleeve, and a solid material drain pipe, after the reaction inside the reactor is completed, the filter sleeve can be used to separate the solid and liquid. The separated liquid will be discharged and collected through the drain pipe, while the separated solid will enter the collection tank through the solid material drain pipe for secondary solid-liquid separation, so that the reaction products can be fully extracted, thus making the extraction of reaction products more thorough.

[0014] By designing an inner tank and a cavity jacket, a cavity jacket is formed between the inner tank and the side wall of the reactor during use. This cavity jacket can be filled with heat-insulating and high-pressure resistant material, thereby improving the reactor's high-temperature and high-pressure resistance and extending its service life. After the reaction is completed, the reactor and the collection tank can be rinsed through water inlet pipe one and water inlet pipe two respectively to prevent reactant residues from remaining inside the reactor and collection tank, facilitating their next use.

[0019] Please see Figures 1-5 A novel high-temperature and high-pressure internal combustion heating reactor device includes a support leg 1, a support frame 2, and a reactor 3. The support frame 2 is fixedly connected to the top of the support leg 1 for support. The reactor 3 for reaction processing is fixedly installed on the inner side wall of the support frame 2.

A high-pressure pump inlet pipe 9 for filling materials is fixedly connected to the bottom surface of the reactor 3. The output end of the high-pressure pump inlet pipe 9 is connected to the interior of the reactor 3 for convenient... The material enters the interior of the reactor via the high-pressure pump inlet pipe 9. A gas inlet pipe 10 for adding natural gas and a gas inlet pipe 2 for adding oxygen are fixedly connected to the bottom surface of the reactor 3. The output ends of both gas inlet pipes 10 and 21 are connected to the interior of the reactor 3, facilitating the entry of natural gas and oxygen. A heating rod 12 for ignition is fixedly connected to the ground of the reactor 3 between gas inlet pipes 10 and 21. The heating rod 12 ignites and burns the natural gas and oxygen inside the reactor 3, promoting the heating reaction inside the reactor 3 and accelerating the reaction. A cooling device is installed at the end of the outlet pipe 8 away from the sealing cover 4. An extraction and separation device is installed at the bottom of the reactor 3. Filter devices are installed inside the reactor 3 and the extraction and separation device. A heat-insulating and high-pressure resistant device is installed inside the reactor 3.

[0020] Please see Figures 1-2The cooling device includes a liquid nitrogen cooler 13, which is fixedly connected to the end of the gas outlet pipe 8 away from the sealing cover 4 via a connecting pipe.

Secondly, the hot water discharged from the hot water outlet 20 can be used to heat the materials coming out of the high-pressure pump inlet pipe 9, achieving heat exchange. After the heat exchange, the cooled hot water will continue to enter the water jacket 18 through the cold water inlet 19, achieving water recycling.

[0023] Please see Figures 2-4 The extraction and separation device includes a drain pipe 21 for discharging liquid, which is fixedly connected to the middle of the bottom surface of the reactor 3. Inside the reactor 3, at the drain pipe 21, a filter sleeve 22 for solid-liquid separation is fixedly connected to ensure that the filter sleeve 22 can separate the liquid and solid material inside the reactor 3. At the bottom of the reactor 3, at the side of the drain pipe 21, a solid material discharge pipe 23 for discharging solid material is fixedly connected to ensure that the solid material discharge pipe 23 can discharge the solid material inside the reactor 3. An electric valve 24 for controlling the discharge is fixedly installed on the solid material discharge pipe 23, and the discharge of the solid material discharge pipe 23 can be controlled by the electric valve 24.

A water inlet pipe 26 for adding water is fixedly connected to the bottom of the collection tank 25. A liquid discharge pipe 27 for discharging liquid is fixedly connected to the middle of the bottom surface of the collection tank 25.

An electric valve 20 for controlling the discharge is fixedly installed on the solid material discharge pipe 29. The discharge volume of the solid material discharge pipe 29 can be controlled by the electric valve 20. An exhaust pipe 31 for discharging gas is fixedly connected to the top surface of the collection tank 25.

[0026] Please see Figures 2-4 The heat-insulating and high-pressure resistant device includes an inner tank 32, which is fixedly connected to the inner wall of the reactor 3.

[0027] Please see Figures 2-4 A cavity jacket 33 is formed between the inner tank 32 and the inner wall of the reactor 3.

[0028] Working principle: When reactor 3 is running, reactants are filled into reactor 3 through high-pressure pump inlet pipe 9. Then, inlet pipe 10, inlet pipe 2, and heating rod 12 are opened. Natural gas is added into reactor 3 through inlet pipe 10, and oxygen is added through inlet pipe 2. Heating rod 12 ignites and combusts the natural gas and oxygen inside reactor 3, promoting the heating reaction inside reactor 3. Next, liquid nitrogen cooler 13 and water cooler 14 are opened, and cold water is added into water jacket 18 through cold water inlet 19. The cold water in water jacket 18 cools the high-temperature gas at the top of reactor 3, causing some unreacted reactants to fall back and react again. The cold water in water jacket 18, after heat exchange, is discharged through hot water outlet 20. The hot water discharged from hot water outlet 20 can then be used to heat the material coming out of high-pressure pump inlet pipe 9, achieving heat exchange. After the heat exchange, the cooled hot water continues to enter water jacket 18 through cold water inlet 19, achieving water recycling. The high-temperature gas generated after the reaction inside reactor 3 enters the liquid nitrogen cooler 13 through a connecting pipe for cooling, completing gas-liquid separation. The liquid separated by the liquid nitrogen cooler 13 continues to enter the water cooler 14. After being cooled by the water cooler 14, the liquid enters the collection tank 15 through the back pressure valve 17. Finally, the cooled liquid is discharged and collected through the cold liquid outlet 16. The reaction products inside reactor 3 are filtered by the filter sleeve 22. The filtered liquid is discharged through the drain pipe 21, and the filtered solids are processed through the solidification pipe 22. The material discharge pipe 23 discharges into the collection tank 25 for secondary separation. After entering the collection tank 25, the solid material is filtered by the filter sleeve 28. The filtered liquid is discharged through the drain pipe 27. The solid material after secondary separation is discharged through the solid material discharge pipe 29 and collected. After the reaction is completed, water can be added to the inside of the reactor 3 through the water inlet pipe 5 to rinse the reactor 3. Then, water can be added to the collection tank 25 through the water inlet pipe 26 to rinse the collection tank 25, which facilitates the reuse of the reactor 3.
