Description

Technical Field

[0001] This utility model relates to the field of petrochemical teaching equipment technology, specifically a simulation teaching and training device for a petrochemical reactor. Background Technology

[0002] In the petrochemical industry, pressure vessels are widely used as key equipment in various production processes, such as reaction, storage, and separation. However, traditional petrochemical education faces many difficulties in imparting knowledge and practical skills related to pressure vessels:

[0003] High Risks of On-Site Learning: Real petrochemical pressure vessels are typically located in extremely dangerous environments such as high temperature, high pressure, and toxic and harmful media. Trainees directly entering these environments face significant safety risks, and accidents could have disastrous consequences. Furthermore, the complex production layout and continuous operation processes on-site make it difficult for trainees to focus on key operational points of the pressure vessels. Limited Practical Training: Purchasing and maintaining real petrochemical pressure vessels is costly, and schools and training institutions simply cannot afford to equip themselves with a sufficient number and variety of pressure vessels for trainees to operate. This results in trainees largely engaging in theoretical learning without practical application, making it difficult to cultivate highly skilled personnel who meet industry demands. 3. Poor Teaching Effectiveness: Traditional theoretical teaching methods, relying solely on books and pictures to explain the structure, principles, and processes of pressure vessels, are too abstract, making it difficult for trainees to understand and form a direct understanding. Even with some simple model demonstrations, they cannot simulate the dynamic operation under real working conditions, failing to stimulate trainees' interest and initiative. To address these issues, this invention designs a simulation teaching and training device for petrochemical reactors. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a simulation teaching and training device for petrochemical reactors, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simulation teaching and training device for a petrochemical reactor, comprising a ground, a reactor fixed to the top of the ground by a support rod, a reactor fragment fixed to the front end of the reactor, a simulated pressure gauge on the top of the reactor, a reactor temperature gauge fixed to the right end of the simulated pressure gauge, the reactor temperature gauge being fixedly connected to the reactor, a simulated stirring motor fixed to the right end of the reactor temperature gauge, a simulated safety valve fixed to the right end of the simulated stirring motor, and a safety valve fixedly connected to the reactor at its bottom via a safety valve connecting pipe. A safety valve relief head is slidably connected to the upper end of the valve. A safety valve relief pipe is fixed to the right end of the simulated safety valve via a relief pipe connecting flange. An overflow pipe is provided at the right end of the safety valve relief pipe. The overflow pipe is fixedly connected to the reactor. A sealing pipe is also fixed to the top of the reactor. A connecting pipe is provided at the right end of the reactor. A gate valve connector is fixed to the upper end of the connecting pipe. A simulated gate valve is fixed to the right end of the gate valve connector via a flange. A simulated pressure gauge is provided at the bottom of the simulated gate valve via a connecting pipe. A bottom temperature gauge is provided at the bottom of the simulated pressure gauge via the connecting pipe. A simulated drain pipe is also provided at the bottom of the reactor.

[0006] Preferably, the left end of the bottom thermometer is fixedly connected to the connecting pipe, the top of the bottom thermometer is fixed with a connecting pipe pressure measuring tube, the right end of the connecting pipe pressure measuring tube is fixed to the connecting pipe simulation pressure gauge, the front end of the connecting pipe pressure measuring tube is also fixed with a connecting pipe pressure valve, the top of the connecting pipe is fixedly connected to an output pipe through a flange, and the output pipe is fixedly connected to the reaction vessel.

[0007] Preferably, a drain connection pipe is fixed at the bottom of the reactor, and the bottom of the drain connection pipe is fixedly connected to the simulated drain pipe via a drain flange. A simulated drain valve is also fixed at the front end of the simulated drain pipe.

[0008] Preferably, a pressure measuring tube is fixed to the top of the reactor, and the pressure measuring tube is fixedly connected to the simulated pressure gauge on its top. A pressure valve is also fixed to the front end of the pressure measuring tube.

[0009] Preferably, a stirring shaft is rotatably connected to the top of the reactor, the stirring shaft is rotatably connected to the simulated stirring motor on its top, the simulated stirring motor is fixedly connected to the reactor, and a stirring motor noise simulator is fixed to the front end of the simulated stirring motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention can realistically simulate subtle changes in pressure data in reactors, dynamic changes in pipeline pressure data, and even extreme situations such as overflow, fire, and explosion, as well as abnormal operating conditions of feed pumps. It allows trainees to directly confront various possible situations in a virtual environment, accumulating rich experience in handling such situations. This device can simulate various physical faults that may occur in a reactor, including overflow, fire, explosion, tank rupture, and safety valve activation. For overflow faults, it can simulate scenarios where material overflows due to improper liquid level control or excessive feed, teaching operators how to promptly detect overflow signs and take corrective measures. In terms of fire simulation, it can simulate fires caused by leaked flammable materials encountering open flames or high temperatures. Furthermore, the training program enhances operators' fire emergency response capabilities, including how to correctly use fire extinguishing equipment and organize personnel evacuation. Regarding the crucial safety valve tripping mechanism, the device accurately simulates its tripping action when the pressure reaches a set value, as well as the pressure changes and material discharge after tripping. This allows operators to clearly understand the working principle of the safety valve and its operational status in actual situations, mastering the subsequent handling procedures after the safety valve trips. This ensures correct response in real-world scenarios, protecting the safety of the reactor and personnel. Through the simulation of these physical faults, operators can practice repeatedly in a safe training environment, improving their ability to handle sudden malfunctions and providing strong support for the safe operation of petrochemical production.

[0012] When the pressure inside the reactor rises sharply due to uncontrolled chemical reaction, excessive external heat input, or material blockage, exceeding the pressure limit that the reactor can withstand, the reactor fragments will rupture rapidly, releasing the pressure inside the reactor and preventing serious accidents such as explosions due to overpressure, thus protecting the equipment and personnel safety.

[0013] This invention can accurately simulate the changes in internal temperature and pressure data of a reactor under normal operating conditions. By accurately setting and simulating various process parameters, operators can gain a deeper understanding of the reactor's operating patterns during stable production, and become familiar with the fluctuation range of temperature and pressure under normal operating conditions and their interrelationships. This helps operators accurately judge the reactor's operating status in actual work, promptly identify potential problems, and ensure stable production. It also has the ability to simulate changes in internal temperature and pressure data of the reactor under abnormal operating conditions, simulating various situations that lead to abnormal temperature and pressure changes, such as abnormal feeding, discharge blockage, and cooling system failure. By dealing with these abnormal operating conditions in a simulated environment, operators can accumulate rich experience, improve their emergency response capabilities when facing sudden anomalies in actual production, and effectively reduce the risk of accidents.

[0024] Before using this device, operators should select an indoor space based on the teaching scale, considering area, ceiling height, ventilation, and lighting conditions to ensure sufficient space for training equipment and student activities. The student operation area and teacher guidance area should be divided according to teaching logic. The student operation area should ensure reasonable spacing between equipment to facilitate student interaction; the teacher guidance area should facilitate observation of student operations and be equipped with teaching equipment such as a projector. A reasonable plan for passageways should be implemented to ensure emergency evacuation. Simultaneously, the site should undergo safety renovations including anti-slip and fireproofing measures. Furthermore, a skid-mounted integrated structure design should be adopted, with assembly and debugging completed in the factory. Construction should strictly adhere to the drawings, checking the connection and fixation of components. Based on the site layout, the device should be quickly positioned, its level and verticality calibrated, and connections tightened again to ensure stability and reliability. The simulation training then begins.

Simulated scenarios such as overflow, spillage, and fire are triggered, with students informed of the background and requirements beforehand. Students handle emergencies according to the emergency plan, such as stopping the feed and activating the simulated drain valve 501 in case of overflow, allowing the material inside the reactor 2 to be discharged through the drain connection pipe 503 to the simulated drain pipe 5.

An evaluation and summary are conducted afterward, with suggestions for improvement. Simultaneously, during use, instructors can control the simulated stirring motor 4 to drive the stirring motor noise simulator 402, thereby stirring the material inside the reactor 2. To ensure the accuracy of the simulation, if it is necessary to simulate abnormal noise from the simulated stirring motor 4, the teacher can control the abnormal noise simulator 402 to emit abnormal noise to simulate the abnormality of the simulated stirring motor 4. At the same time, when adding materials, after the reactor 2 is full, the excess material is discharged through the overflow pipe 204. Furthermore, the teacher can control the simulated gate valve 7 to allow the material inside the reactor 2 to flow into the connecting pipe 6. By rotating the connecting pipe pressure valve 603, the simulated pressure gauge 602 can monitor the internal pressure of the connecting pipe 6. At the same time, the internal temperature of the connecting pipe 6 can be monitored through the bottom temperature gauge 601, thereby simulating the changes in internal pressure and temperature of the connecting pipe 6.Simultaneously, this device can simulate the pressure relief state of the reactor 2. When the internal pressure of the reactor 2 is too high, the material reaches the simulated safety valve 8 along the safety valve connecting pipe 803, thereby pushing the safety valve relief head 802 upward, allowing the material to flow out along the safety valve relief pipe 801. It can also simulate the failure state of the safety valve relief head 802. When the safety valve relief head 802 fails, the reactor fragment 201 deforms due to the excessive internal pressure of the reactor 2, making it convenient for trainees to observe.

[0025] The workflow of this utility model is as follows: Before using this device, the operator selects an indoor venue based on the teaching scale, considering the area, ceiling height, ventilation, and lighting conditions to ensure sufficient space for training equipment and student activities; the student operation area and the teacher guidance area are divided according to the teaching logic. The student operation area ensures reasonable spacing between equipment to facilitate student operation and communication; the teacher guidance area facilitates observation of student operation and is equipped with teaching equipment such as a projector; the passageway is rationally planned to ensure emergency evacuation; simultaneously, the venue undergoes safety renovations such as anti-slip and fireproofing, and a skid-mounted overall structure design is adopted. Assembly and debugging of each part are completed in the factory, construction is strictly carried out according to the drawings, and the connection and fixing of components are checked. Furthermore, the device is quickly positioned according to the venue layout, and the horizontal and vertical alignment is calibrated. Secure the connection points to ensure the device's stability and reliability before commencing simulation training. The instructor first provides theoretical explanations, using multimedia presentations to demonstrate the commissioning process, procedures, and precautions, helping students gain a direct understanding. Under the instructor's guidance, students operate the simulation device according to specifications, from equipment checks and parameter settings to starting the pressure vessel. The instructor corrects errors in real time. After the operation, students summarize and discuss their findings. Further simulations of abnormal data such as pressure increases and temperature fluctuations are performed on this device. Students can monitor the internal pressure and temperature of the reactor 2 using the simulated pressure gauge 3 and the reactor temperature gauge 303. Simultaneously, the reactor pressure valve 301 facilitates monitoring. The instructor then guides students to determine whether the problem is an equipment malfunction or a parameter setting issue. Based on this, solutions are developed, such as adjusting parameters, inspecting components, and activating backup equipment. Teachers supervise the operation process, triggering simulated scenarios such as overflow, spillage, and fire. Students are informed of the background and requirements in advance. When faced with emergencies, students handle them according to the emergency plan, such as stopping the feed and activating the simulated drain valve 501 in case of overflow, allowing the material inside the reactor 2 to be discharged through the drain connection pipe 503 to the simulated drain pipe 5. In case of fire, students activate the fire extinguishing system and organize evacuation. Teachers observe and record students' reaction speed, decision-making, and operational abilities. After the operation, an evaluation and summary are conducted, and improvement suggestions are made. Simultaneously, during use, teachers can control the simulated stirring motor 4 to simulate abnormal noises. The device 402 rotates, thereby stirring the materials inside the reactor 2 to ensure the accuracy of the simulation. If it is necessary to simulate abnormal noise from the simulated stirring motor 4, the teacher can control the simulation motor noise simulator 402 to emit abnormal noise to simulate the abnormality of the simulated stirring motor 4. At the same time, when adding materials, after the reactor 2 is full, the excess material is discharged through the overflow pipe 204. Furthermore, the teacher can control the simulated gate valve 7 to allow the materials inside the reactor 2 to flow into the connecting pipe 6. By rotating the connecting pipe pressure valve 603, the simulated pressure gauge 602 can monitor the internal pressure of the connecting pipe 6. At the same time, the internal temperature of the connecting pipe 6 can be monitored through the bottom temperature gauge 601.This device simulates the pressure and temperature changes inside the connecting pipe 6. Simultaneously, it can simulate the pressure relief state of the reactor 2. When the internal pressure of the reactor 2 is too high, the material travels along the safety valve connecting pipe 803 to the simulated safety valve 8, pushing the safety valve relief head 802 upwards. This allows the material to flow out along the safety valve relief pipe 801. It can also simulate the failure state of the safety valve relief head 802. When the safety valve relief head 802 fails, the reactor fragment 201 deforms due to the excessive internal pressure of the reactor 2, facilitating observation by trainees.
