Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a heat-insulating reaction vessel. Background Technology

[0002] A reaction vessel is a closed pressure vessel widely used in industries such as petroleum, chemical, and food processing. It is primarily used to complete chemical processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. An insulated reaction vessel, on the other hand, refers to any reaction vessel equipped with an insulation layer or heat-resistant layer. It provides a safe and controllable environment for raw materials to undergo chemical reactions within it to produce the desired product.

[0003] Application No. 202120047323.1 discloses a compounding reaction vessel. This patent includes a reaction vessel body with a feeding port, a stirring motor, and an online pH detection device at the top. The stirring motor is driven by a stirring shaft, which has stirring blades. A U-shaped stirring paddle is located inside the reaction vessel body. The U-shaped stirring paddle includes a cylindrical side paddle. A first rotating bearing and a second rotating bearing are respectively located at the top and bottom of the cylindrical side paddle. The inner rings of the first and second rotating bearings are embedded in the cylindrical side paddle, and two sets of rotating plates are fixedly connected to the outer rings. Scrapers are provided along the outer edges of the rotating plates. This invention, when performing chemical compounding and neutralization reactions, not only ensures thorough stirring and uniform dispersion of raw materials, but also allows for online monitoring of the neutralization process, improving product quality stability. Furthermore, it effectively prevents solid raw materials from adhering to the inner wall and corners of the vessel. After use, the reaction vessel can be efficiently cleaned, greatly improving production efficiency.

[0004] While the above comparison documents can prevent solid raw materials from adhering to the inner wall and corners of the reactor, petroleum raw materials usually contain solid impurities and heavy colloids. If the petroleum raw materials are transported into the main reaction zone at the bottom of the reactor without removing impurities, it is easy to clog the pipes and valves, and coke will be deposited at the bottom of the equipment, affecting the heat transfer efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a heat-insulating reactor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating reactor, comprising a lower reactor body, an upper reactor body, a feed pipe, and a discharge pipe. The upper reactor body is bolted to the top of the outer wall of the lower reactor body, and a feed pipe is installed on the outer side of the top of the upper reactor body. A discharge pipe is connected to the middle of the bottom of the lower reactor body. A servo motor is installed at the middle of the top of the lower reactor body, and a rotating seat is fixedly connected to the bottom output end of the servo motor. An equal-angle discharge port is opened on the outer wall of the rotating seat. A filter cylinder is provided on the outer wall of the rotating seat, and the top of the filter cylinder is fixedly connected to the inner wall of the lower reactor body. The middle of the filter cylinder has an "O"-shaped structure, and the bottom of the filter cylinder has a conical structure that is larger at the top and smaller at the bottom.

[0007] The centrifugal force generated when the rotating seat rotates will throw the petroleum raw material inside through the outlet, so that the petroleum raw material comes into contact with the filter cylinder, and then the petroleum raw material is filtered through the filter cylinder, so that the solid impurities in the crude oil are separated by the filter cylinder.

[0008] Preferably, a diversion tube is fixedly connected to the top of the inner tank of the upper tank of the reactor, and the bottom of the diversion tube has a conical structure that is larger at the top and smaller at the bottom, and a feeding hole is opened in the middle of the bottom of the diversion tube. The outer wall of the lower tank of the reactor is connected to a heat insulation layer.

[0009] The crude oil separated by the filter cartridge will be blocked by the diversion tube.

[0010] Preferably, a support plate is fixedly connected to the middle of the inner wall of the upper tank of the reactor, and a drainage hole is opened in the middle of the support plate, and the drainage holes are distributed at equal angles.

[0011] Afterwards, the crude oil will flow through the drainage holes inside the support plate to the lower tank of the reactor.

[0012] Preferably, a drainage plate is fixedly connected to the inner wall of the support plate, and the drainage plate has a conical structure that is smaller at the top and larger at the bottom. A rotating column is fixedly connected to the middle of the bottom end of the rotating seat.

[0013] The crude oil flows along the guide plate, forming a thin liquid film on the outer wall of the guide plate as it flows downwards. This process increases the surface area of ​​the crude oil by several times.

[0014] Preferably, a stirring rod is installed at the bottom of the outer wall of the rotating column, and the stirring rod has a "U" shaped structure. The middle part of the diversion plate has an movable hole corresponding to the rotating column.

[0015] Petroleum feedstock enters the lower tank of the reactor, where the rotating column drives the stirring rod to rotate, thereby agitating the petroleum feedstock and chemical solvent at high temperature, causing the petroleum feedstock to undergo a chemical reaction inside the reactor.

[0016] Preferably, a protective plate is installed in the middle of the outer wall of the upper tank of the reactor, and a conveying pipe is connected inside the protective plate. An air inlet pipe is installed on one side of the outer wall of the conveying pipe.

[0017] Hydrogen is introduced into the delivery pipeline through the inlet pipe. At this time, the delivery pipeline is protected by a protective plate. Then, the delivery pipeline introduces the hydrogen into the gas supply pipeline.

[0018] Preferably, the inner wall of the air intake pipe is connected to an air delivery pipe, and the air delivery pipe is distributed at equal angles and has an "L" shaped structure.

[0019] Hydrogen is delivered to the priming plate through a gas delivery pipeline. At this point, the hydrogen comes into contact with the crude oil, which forms a liquid film on the outer wall of the priming plate, and reacts. Subsequently, the hydrogen reacts with harmful impurities in the petroleum, hydrogenating unstable olefins into more stable alkanes and improving the quality of the oil.

[0020] Preferably, the bottom output end of the air supply pipe is located at the diversion plate, and an air vent is provided on the outer side of the top of the diversion cylinder, with the air vents distributed at equal angles.

[0021] Hydrogen rises and enters the venting tube through the ventilation channel, where it reacts with the crude oil inside the venting tube.

[0022] As can be seen from the above, the heat-insulating reactor provided by this utility model has the following beneficial effects.

[0023] 1. The rotation of the rotating seat and the filter cartridge work together to generate centrifugal force at high speed, which quickly and efficiently separates solid impurities in the petroleum feedstock through the filter cartridge, preventing solid impurities in the crude oil from entering the lower tank of the reactor, which could lead to blockage of pipes and valves and increase maintenance costs.

[0024] 2. By allowing hydrogen to react with crude oil in a liquid film on the outer wall of the guide plate, the surface area of ​​the liquid film increases the gas-liquid contact area, enabling hydrogen to dissolve and diffuse into the petroleum more quickly and evenly, thus accelerating the reaction rate. This prevents heavy components in the petroleum from undergoing condensation reactions at high temperatures, forming coke deposits inside the equipment, thereby inhibiting coking and protecting the equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-8 This utility model provides a technical solution: a heat-insulating reactor, including a lower reactor body 1, an upper reactor body 2, a feed pipe 3, and a discharge pipe 4. The upper reactor body 2 is bolted to the top of the outer wall of the lower reactor body 1, and the feed pipe 3 is installed on the outer side of the top of the upper reactor body 2. The discharge pipe 4 is connected to the middle of the bottom of the lower reactor body 1. A servo motor 5 is installed at the middle of the top of the lower reactor body 1, and a rotating seat 6 is fixedly connected to the bottom output end of the servo motor 5. The outer wall of the rotating seat 6 has a discharge port 7 with an equal included angle. There is a filter cylinder 8, and the top of the filter cylinder 8 is fixedly connected to the inner wall of the lower tank 1 of the reactor. The middle of the filter cylinder 8 has an "O" shaped structure, and the bottom of the filter cylinder 8 has a conical structure that is larger at the top and smaller at the bottom. The top of the upper tank 2 of the reactor is fixedly connected to a flow guide cylinder 9, and the bottom of the flow guide cylinder 9 has a conical structure that is larger at the top and smaller at the bottom. A feeding hole is opened in the middle of the bottom of the flow guide cylinder 9. The outer wall of the lower tank 1 of the reactor is connected to a heat insulation layer. The middle of the inner wall of the upper tank 2 of the reactor is fixedly connected to a support plate 10, and a flow guide hole 11 is opened in the middle of the support plate 10. The flow guide holes 11 are distributed at equal angles.

[0029] For specific implementation, please refer to Figures 1-4First, the petroleum feedstock is introduced into the upper tank 2 of the reactor through the feed pipe 3. At this time, the petroleum feedstock will fall into the rotating seat 6. The servo motor 5 is started in advance to drive the rotating seat 6 to rotate at high speed. Then, the centrifugal force generated by the rotation of the rotating seat 6 will throw the petroleum feedstock inside through the discharge port 7, so that the petroleum feedstock comes into contact with the filter cylinder 8. Then, the petroleum feedstock is filtered through the filter cylinder 8, so that solid impurities in the crude oil, such as mud, rust and heavy colloids, are separated by the filter cylinder 8. Then, the crude oil separated by the filter cylinder 8 is blocked by the diversion cylinder 9, thereby preventing solid impurities in the crude oil from entering the lower tank 1 of the reactor, causing pipe and valve blockage and increasing maintenance costs.

[0030] See Figure 5 and Figure 6 After filtration, the crude oil will fall along the guide tube 9 to the guide plate 12. Then the crude oil will flow along the guide plate 12. At this time, the crude oil forms a thin liquid film on the outer wall of the guide plate 12 and flows downward. Afterward, the crude oil will flow through the guide hole 11 inside the support plate 10 to the lower tank 1 of the reactor. Thus, the crude oil forms a liquid film through the guide plate 12, which multiplies its surface area.

[0031] See Figure 7 and Figure 8 A flow guide plate 12 is fixedly connected to the inner wall of the support plate 10, and the flow guide plate 12 has a conical structure with a smaller upper part and a larger lower part. A rotating column 13 is fixedly connected to the middle of the bottom of the rotating seat 6. A stirring rod 14 is installed at the bottom of the outer wall of the rotating column 13, and the stirring rod 14 has a "U" shaped structure. A movable hole corresponding to the rotating column 13 is opened in the middle of the flow guide plate 12. A protective plate 15 is installed in the middle of the outer wall of the upper tank 2 of the reactor, and a conveying pipe 16 is connected inside the protective plate 15. An air inlet pipe 17 is installed on one side of the outer wall of the conveying pipe 16. An air supply pipe 18 is connected to the inner wall of the air inlet pipe 17, and the air supply pipe 18 is distributed at equal angles and has an "L" shaped structure. The bottom output end of the air supply pipe 18 is located at the flow guide plate 12. A ventilation groove 19 is opened on the outer side of the top of the flow guide cylinder 9, and the ventilation groove 19 is distributed at equal angles.

[0032] In practice, hydrogen is introduced into the delivery pipe 16 through the inlet pipe 17. At this time, the delivery pipe 16 is protected by the protective plate 15. Then, the delivery pipe 16 introduces the hydrogen into the gas delivery pipe 18, and then the gas delivery pipe 18 delivers the hydrogen to the diversion plate 12. At this time, the hydrogen comes into contact with the crude oil, which is in liquid film on the outer wall of the diversion plate 12, and reacts. Then, the hydrogen reacts with the harmful impurities in the petroleum, hydrogenating the unstable olefins into more stable alkanes, improving the quality of the oil, and allowing the hydrogen to fully dissolve and mix into the petroleum. At the same time, the hydrogen rises and enters the diversion cylinder 9 through the ventilation groove 19, thereby reacting with the crude oil inside the diversion cylinder 9.

[0033] Furthermore, the increased surface area of ​​the liquid film increases the gas-liquid contact area, allowing hydrogen to dissolve and diffuse into the petroleum more quickly and evenly, accelerating the reaction rate and preparing for subsequent deep reactions. This also prevents heavy components in the petroleum from undergoing condensation reactions at high temperatures, forming coke that deposits inside the equipment, thereby inhibiting coking and protecting the equipment.

[0034] Finally, the filtered and hydrogenated petroleum feedstock enters the lower tank 1 of the reactor. At this time, the rotating column 13 drives the stirring rod 14 to rotate, thereby stirring the petroleum feedstock and chemical solvent at high temperature, so that the petroleum feedstock undergoes a chemical reaction inside the reactor. Afterwards, the reacted petroleum feedstock is discharged from the reactor through the discharge pipe 4.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
