Description

Technical Field

[0001] The invention relates to the technical field of experimental equipment, in particular to a flowing fire combustion spread simulation device under the existence of water surface flow and waves. Background Art

[0002] In the context of economic globalization, international oil and energy transportation often adopts sea transportation, and a large amount of oil is stored at sea. During transportation, liquid fuel leakage accidents occur from time to time. Once an oil leak occurs, the spilled oil will spread with the ocean currents and can be easily ignited, causing a flowing fire on the water. As the burning oil spreads, the burning area will expand over time, posing a huge threat to the life safety of personnel, ships and nearby equipment, causing the accident to expand. At the same time, during the diffusion and combustion of oil, there are ocean currents and environmental winds, which cause the water surface to flow and wave state, which makes the development of the flowing fire on the water unpredictable and increases the difficulty of extinguishing. Therefore, developing a flowing fire simulation device on the water to simulate the diffusion and combustion of oil in the presence of water surface flow and waves, and studying the diffusion law and combustion characteristics are of great theoretical and practical significance for effective planning of fire fighting and prevention of accident escalation.

[0003] The fluidity of flowing fire makes liquid fuel leak fire more dangerous than oil pool fire. Scholars have conducted relevant research on flowing fire simulation devices. Publication (Announcement) No.: CN205263045U provides a splicable inclination-adjustable land flowing fire experimental platform, which can adjust the slope to simulate the flowing and burning of leaked oil on slopes with different inclination angles. The data acquisition and control system collects and analyzes key parameters such as the mass loss rate of the oil, the combustion flame temperature, and the thermal radiation, but it cannot simulate the flow on water. Publication (Announcement) No.: CN210925183U provides a mesoscale tunnel flowing fire simulation device, which can be used to conduct flowing fire experiments with different wind speeds and different slopes using a variable slope system and a fan system, and obtain the changes in parameters such as the spread distance and burning rate of tunnel flowing fire, and study the spread and combustion laws of tunnel flowing fire, but does not consider the situation of flowing fire on water. Li et al. proposed a water flowing fire simulation device on a static water surface. A water cushion layer of a certain thickness was added to a concrete rectangular tank. A vane pump was used to adjust the speed to pass the oil into the rectangular tank. The flame temperature, flame external radiation and other parameters were measured to study the spread and combustion mechanism of continuous leakage water flowing fire under different leakage rates. However, only the static water surface conditions were considered, which was quite different from the actual leakage. Publication (Announcement) No.: CN216525629U, provides an on-water liquid fire spread experimental platform with adjustable width and wave-making intensity. Waves are made using a wave-making pump, and the initial temperature of the water is controlled by a water temperature heater. A certain amount of liquid fuel floating on the water is ignited to simulate the instantaneous leakage flowing fire spread under wave conditions. The temperature data is measured to study the influence of waves and water temperature on flame spread. However, the flow of water and continuous leakage are not considered, nor is the delayed ignition considered.

[0004] Through the investigation of existing related technologies, it can be found that the existing flowing fire simulation devices have certain limitations: the simulation devices for flowing fire are mostly for flowing fire on land, and there are fewer devices for flowing fire on water. Moreover, the only simulation devices for flowing fire on water do not take into account the flow of water bodies, which will affect the diffusion and combustion behavior of oil products. At the same time, the existing devices rarely pay attention to the delayed ignition time. Compared with instant ignition, the maximum diffusion and combustion area of ​​flowing fire under different delayed ignition times is quite different, which affects the danger of flowing fire. In the process of offshore oil transportation, leakage is very likely to occur under unexpected circumstances, forming a continuous leakage flowing fire that flows and burns at the same time. During the leakage and combustion process, the flowing fire will be affected by the flow and waves of the surrounding water bodies. Relying on the existing devices, it is difficult to accurately reflect the scene of oil leakage and flowing fire during water transportation. Therefore, it is urgent to develop a device to simulate the diffusion and combustion of continuous leakage flowing fire of oil products under the conditions of water surface flow and wave existence, and clarify the influence of waves and water flow on the diffusion behavior and combustion characteristics of flowing fire.

[0039] Please continue to refer to Figure 1 , the flow trough module 100 includes a flow trough 110, a rectangular flow trough 120, and an overflow trough 130. The water flows into the rectangular flow trough 120 through the flow trough 110, and finally the overflowed water flows into the overflow trough 130. The water flows from the flow trough 110 into the rectangular flow trough 120 through the filter screen 111, so that the water flow is stable and uniform. The rectangular flow trough 120 has a combustion chamber that is open upward and has a certain depth for accommodating a water cushion layer. The flow trough 110, the rectangular flow trough 120 and the overflow trough 130 are connected end to end in sequence, and the whole is made of stainless steel, and are all placed on the support table 140 to ensure that the flow trough module 100 is horizontal, reduce the impact on the experiment, and improve the experimental accuracy. The adjustable baffle 131 can adjust the thickness of the water cushion layer to simulate different water levels.

[0040] It should be noted that a liquid level meter 150 is attached to the outer side wall of the rectangular flow trough 120 for real-time monitoring of the water level inside the rectangular flow trough 120 .

[0041] Please refer to Figure 1 and Figure 3 , the circulating water supply module 200 includes a water storage barrel 210 and a water supply pump 220. The water storage barrel 210 is set on the ground to store the water required for circulation. One end of the thin water pipe 230 extends into the water storage barrel 210, and the other end is connected to the distribution flow trough 110. The end of the main pipe of the thin water pipe 230 connected to the distribution flow trough 110 is divided into three branches, so that the water flow entering the distribution flow trough 110 is uniform. The water supply pump 220 is set on the thin water pipe 230 to drive the water in the water storage barrel 210 to flow to the distribution flow trough 110.

The oil supply barrel 310 stores the oil required for a single experiment, and the oil supply barrel 310 can effectively block silence to improve the safety of the oil supply barrel 310. One end of the hose 330 extends into the bottom of the oil supply barrel 310, and the other end extends into the combustion chamber of the rectangular flow groove 120. The peristaltic pump 320 is arranged on the hose 330 to transport the oil to the combustion chamber of the rectangular flow groove 120 at a stable flow rate. After reaching the water cushion layer, the oil fuel is evenly diffused to the surroundings, thereby simulating the diffusion of oil leakage under flowing water surface conditions. At the same time, the ignition device 160 will automatically ignite the oil after the preset delayed ignition time, which can be used to simulate the combustion of oil on the flowing water surface after leakage. Among them, the preset delayed ignition time is usually selected according to the experimental objectives.

[0043] It should be noted that the hose 330 is wrapped with a heat insulation layer to prevent it from being damaged by flames and affecting the oil supply. The distance between the oil supply barrel 310 and the combustion chamber of the rectangular flow trough 120 is not less than 3m, and a fireproof partition is provided to prevent the oil supply barrel 310 from being ignited during the experiment, thereby ensuring the safety of the experimental process.

[0044] Please continue to refer to Figure 1 The dyeing module 400 is used for dyeing oil products. The dyeing module 400 can directly dye the oil products in the oil supply barrel 310. Dyeing in the barrel can provide a stable dyeing environment, ensuring that the oil products entering the rectangular flow groove 120 are effectively dyed, thereby ensuring that the diffusion of the oil products on the water surface can be clearly observed without ignition.

[0045] Specifically, in this embodiment, the dyeing module 400 further includes a dye supply and a mixer. The dye supply contains dye and is continuously released into the oil supply barrel 310 to ensure that the oil in the oil supply barrel can be dyed. At the same time, the mixer continuously stirs the oil in the oil supply barrel 310 so that the dye and the oil can be fully mixed, thereby improving the experimental accuracy.

[0046] Please refer to Figure 1 and Figure 2 The wave-making module 500 includes a rectangular movable baffle 510, a slide rail 520 and a stepper motor 530. The slide rail 520 is arranged at the bottom of the rectangular flow trough 120 and is parallel to the side of the rectangular flow trough 120. It is used to fix the rectangular movable baffle 510 and provide a motion track. The specific structure of the slide rail 520 is as follows: Figure 2 As shown, the slide rail 520 includes a slider 521 and a track 522. The slider 521 carries a rectangular movable baffle 510 and can move on the track 522. The stepper motor 530 is used to drive the rectangular movable baffle 510 to reciprocate on the slide rail 520 to form waves, simulating the water surface state where waves exist.

[0047] Specifically, in this embodiment, the stepper motor 530 can adjust the speed to control the movement speed of the rectangular movable baffle 510, simulating waves of different strengths, and is used to study the diffusion and combustion characteristics of oil leakage flow fire under different wave strengths. The height of the rectangular movable baffle 510 is lower than the water cushion layer, and the width is smaller than the width of the narrow side of the rectangular flow groove 120.

[0048] Please continue to refer to Figure 1 In some embodiments of the present invention, the acquisition module 600 includes a first camera 610 and a second camera 620.

The second camera 620 is placed at a position 3 meters away from the long side of the rectangular flow trough 120, and is set at a higher height and captures the water surface of the rectangular flow trough 120 at a certain depression angle, which can clearly capture the diffusion and combustion process of the oil on the water surface, and prevent the equipment from being damaged by the flame.

[0051] Optionally, the precision of the electronic balance 630 is 0.1 g, which can record the change of oil quality more accurately, make the processed combustion rate more accurate, and reduce the experimental error.

[0052] Please continue to refer to Figure 1 The acquisition module 600 also includes a radiation measuring device 640, which includes a calorimeter 641 and a calorimeter support rod 642. The calorimeter 641 is fixed on the calorimeter support rod 642 and placed outside the long side of the rectangular flow groove 120 to measure the intensity of the external radiation heat flux of the flowing flame.

[0053] Optionally, the heat flow meter 640 is a water-cooled radiation heat flow meter, thereby facilitating the acquisition of radiation heat flow data.

[0054] Please continue to refer to Figure 1The acquisition module 600 also includes a point temperature measuring device 650, which includes a thermocouple 651 and a thermocouple support rod 652. There are multiple thermocouples 650, which are fixed on the thermocouple support rod 652 at fixed intervals in the vertical direction to form a thermocouple array to measure the temperature of the flowing fire flame at different heights and obtain the longitudinal temperature distribution of the flowing fire flame. In addition, the thermocouples 650 are arranged horizontally along the long side of the rectangular flow groove 120, and the spacing can be adjusted according to the actual needs of the experiment to measure the flame temperature parameters in the horizontal direction, thereby monitoring the spreading combustion position of the flowing fire.

[0055] Specifically, in this embodiment, the measurement accuracy of the thermocouple 651 can be selected according to the flame temperature of the experimental oil product, and the ends of the thermocouple 651 should be placed on the vertical plane where the central axis of the rectangular flow trough 120 is located to improve the accuracy of the measurement.
