Description

Oil continuous leakage and fire flowing device capable of simulating water surface flow and wave existence

Technical Field

The invention relates to the technical field of experimental equipment, in particular to a drooling fire combustion spreading simulation device in the presence of water surface flow and waves.

Background

Under the background of economic globalization, oil energy transportation in the world usually adopts marine transportation, and a large amount of oil is stored at sea. During transportation, accidents of liquid fuel leakage sometimes occur. Once oil leaks, the overflowed oil diffuses with ocean current and is easily ignited, so that water flows and fires are caused. Along with the diffusion of burning oil, the burning area can enlarge along with the time, constitutes huge threat to personnel's life safety and ship and nearby equipment, causes the accident to enlarge. Meanwhile, in the oil diffusion combustion process, ocean currents and environmental wind exist, so that the water surface is in flowing and wave states, the development of water flowing fire is difficult to predict, and the extinguishing difficulty is increased. Therefore, the overwater fire running simulation device is developed, diffusion and combustion conditions of oil products under the conditions of water surface flow and wave existence are simulated, the diffusion rule and the combustion characteristic are researched, and the device has important theoretical and practical significance for effectively planning fire extinguishment and preventing accident upgrade.

The mobility of a drooling fire makes a liquid fuel leak more dangerous than an oil pool fire. The students have conducted related studies with respect to the sagging fire simulation apparatus. Publication (bulletin) No.: CN205263045U provides a splicing type inclination angle adjustable land flowing fire experiment platform, can adjust the slope, simulates the flowing combustion of leaked oil on the slope surface with different inclination angles, and collects and analyzes the key parameters of the oil such as the mass loss rate, the combustion flame temperature and the heat radiation through a data acquisition control system, but can not simulate the flowing condition on water. Publication (bulletin) no: CN210925183U provides a mesoscale tunnel fire-dripping simulation device, which can be used for carrying out fire-dripping experiments at different wind speeds and different gradients by utilizing a variable gradient system and a fan system, so as to obtain the changes of parameters such as tunnel fire-dripping spread distance and burning rate, and study the tunnel fire-dripping spread and burning rules without considering the water fire-dripping situation. Li et al have provided a static surface water flowing fire simulator, which adds a certain thickness of water cushion layer in a concrete rectangular groove, uses a sliding vane pump to adjust the rotation speed, introduces the oil into the rectangular groove, measures the flame temperature, flame external radiation and other parameters, to study the spreading combustion mechanism of the continuous leakage water flowing fire at different leakage rates, but only considers the surface static condition, and has a larger deviation from the actual leakage. Publication (bulletin) no: CN 216525629U provides a width and wave-making intensity adjustable overwater liquid fire spreading experiment platform, waves are made by using a wave-making pump, a water temperature heater controls the initial temperature of water, instantaneous leakage flowing fire spreading under the condition of waves is simulated by igniting a certain amount of liquid fuel floating on the water, temperature data is measured, the influence of the waves and the temperature of a water body on flame spreading is researched, but the conditions of water body flowing and continuous leakage are not considered, and the condition of delayed ignition is also not considered.

The existing related art is investigated, and the existing flowing fire simulation device has certain limitations: the simulation device for the flowing fire aims at the flowing fire on the land mostly, the device for the flowing fire on the water is few, and the flowing condition of the water body is not considered by the only simulation device for the flowing fire on the water, so that the flowing of the water body can influence the diffusion and combustion behaviors of the oil product. Meanwhile, the existing device rarely pays attention to the delayed ignition time, and compared with the instant ignition, the maximum diffusion combustion area difference of the flowing fire at different delayed ignition times is large, so that the flowing fire hazard is influenced. In the marine oil product transportation process, leakage is easy to occur under unexpected conditions, and continuous leakage flowing fire which flows and burns at the same time is formed. The drooling fire can be influenced by the flow of the surrounding water body and waves in the leakage combustion process. Depending on the existing device, it is difficult to accurately react the leakage flow fire dripping scene of the oil product in the water transportation process. Therefore, it is necessary to develop a device for simulating the diffusion and combustion of the oil product continuous leakage flowing fire under the conditions of water surface flow and wave existence, and to determine the influence of the wave and water flow on the diffusion behavior and combustion characteristic of the flowing fire.
