Abstract
Description
Technical Field
[0001] This utility model relates to the field of simulation rescue model technology, and in particular to a simulation model for fire extinguishing and rescue in a fine chemical plant. Background Technology
[0002] Fine chemical plants are specialized chemical systems centered on the production of high-value-added chemicals. Their production units typically involve high-temperature and high-pressure reactors, precision separation towers, complex piping networks, and hazardous material storage facilities. These plants generally feature flammable and explosive raw materials, highly continuous processes, and high equipment density.
[0003] In existing technologies, the handling of chemical fires mainly relies on two-dimensional planar simulation and experience-based decision-making models: static risk assessment models built based on historical accident data are difficult to dynamically reflect complex coupled processes such as multiphase flow combustion and pressure vessel thermal explosion; conventional numerical simulations mostly use simplified geometric models, which fail to accurately characterize the fire spread path of key structures such as the packing layer and tube bundle heat exchanger inside the tower.
[0004] This method of demonstration has limitations. It cannot intuitively display various simulated fire paths or dynamic performances that are more in line with real-world scenarios. Furthermore, it cannot provide rescue experience from a two-dimensional perspective during drills. Utility Model Content

[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] Reference Figures 1 to 3 This application discloses a fire extinguishing and rescue model simulating a fine chemical plant.
[0029] The visualization isolation room is used to isolate and display the overall model, realizing the dual functions of physical isolation and teaching demonstration. It includes a transparent observation area and a combination of convenient operation and maintenance. The visualization isolation room includes a base plate 2 and a transparent model cover 1. The base plate 2 is made of wear-resistant material, and the transparent model cover 1 is made of acrylic sheet.
[0030] The simulated chemical plant model is fixed in a visualization isolation chamber, specifically on base plate 2. The piping is configured according to the installation and wiring requirements of chemical plants, and is built to scale according to API 520 / 521 specifications. The process is complete, including raw material pretreatment → reaction → separation → purification, and integrates a temperature / pressure / level over-limit early warning system. This is existing technology and not shown in the diagram. There are multiple chemical tank models 3, connected by connecting pipes 31. One end of each connecting pipe 31 has a transition pipe 7 connected to the reaction system 4, which in turn connects to the reagent replenishment device 8. The reaction system 4 has multiple branch pipes 14, each equipped with a chemical discharge valve 13.
[0031] It should be noted that multiple chemical tank models 3, connecting pipes 31, reaction system 4, and multiple branch pipes 14 are all equipped with thermal radiation simulation, flame morphology simulation, and smoke diffusion simulation. Among them, the thermal radiation simulation uses an 8×8 infrared array with an accuracy of ±2℃, combined with a quartz heating tube, to generate a gradient temperature field of 50-800℃. The flame morphology simulation uses a combination of propane fuel from a gas burner and holographic projection to achieve a three-dimensional flame effect. The smoke diffusion simulation uses a Rosin-Rammler model-based atomization system with a particle size distribution of 0.1-10μm, which can create a realistic chemical fire scenario, which is helpful for teaching demonstrations and can simulate rescue paths in various scenarios, helping firefighters with practical drills.
[0032] The inspection device is set up in the simulated chemical plant model area and includes a sensing route 9 and an inspection branch 10. The sensing route 9 and the inspection branch 10 constitute the inspection route, providing the inspection robot 11 with a predetermined route for inspection. The sensing route 9 and the inspection branch 10 are circuit sensing lines. An electromagnetic drive device is set at the bottom of the inspection robot 11, which enables the inspection robot 11 to move on the sensing route 9 and the inspection branch 10.
[0033] To further explain, the sensing route 9 and the patrol branch 10 adopt a dual-track circuit design. The sensing route 9 is the main route, with φ2mm copper wires laid and a 20kHz alternating current flowing through it to form a stable electromagnetic field. The patrol branch 10 is equipped with redundant induction coils, which activate a 10kHz backup frequency when the main route fails. The patrol robot 11 is equipped with a three-axis magnetic sensor array (HMC5883L) chipset at its bottom, which achieves sub-millimeter-level positioning by detecting changes in magnetic field gradient.
[0034] The first fire extinguishing section is located at the position of the chemical tank model 3 in the simulated chemical plant model section; the second fire extinguishing section is located in the reaction system 4 section of the simulated chemical plant model section; it also includes separate fire extinguishing devices 12 scattered in various corners of the simulated chemical plant model section.
[0035] The first fire extinguishing section includes a main fire extinguishing pipe 16, which is connected to a simulated fire extinguisher. One end of the main fire extinguishing pipe 16 is provided with a branch pipe 17 located on one side of multiple chemical tank models 3, and multiple surrounding fire extinguishing pipes 15 are provided on the branch pipe 17.
[0036] The second fire suppression system includes a fire suppression system 5, with a fire suppression pipeline 6 installed at its output end. The fire suppression pipeline 6 is positioned diagonally above the reaction system 4. Both the first and second fire suppression systems include, but are not limited to, high-pressure fine water mist, dry powder spray, foam mixing, and gaseous fire suppression. High-pressure fine water mist, dry powder spray, foam mixing, and gaseous fire suppression all utilize atomizing nozzles. The effectiveness of the spray varies depending on the specific type of fire suppression system used, and the primary control method involves adjusting the spray range and controlling the spray flow rate.
[0037] By setting the simulated fire extinguishing portion after a fire has occurred, where the level of danger is greatest, and by using a location close to the fire extinguishing site, the simulation feedback is highly timely, providing rapid feedback on the situation after the fire, resulting in a better and more realistic presentation.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
