Problems solved by technology

At present, there is a lack of research on fires in large-scale storage tank farms, and there are few relevant experimental data. The rationality of fire separation distances still needs to be further studied. Existing fire protection measures and capabilities are also difficult to play an effective role in fire prevention.

Embodiment 1

[0026] A fire simulation experiment platform in an oil storage tank area in this embodiment is used to simulate a fire situation in a fixed-roof oil storage tank. The schematic diagram of the simulation experiment platform is as follows: figure 1 As shown in the figure, it includes a dike, an oil storage tank 3 is arranged inside the dike, and the tank top of the oil storage tank 3 is composed of two semicircles of the same size, and the two semicircles are movably connected, wherein the first semicircle is fixed on the oil storage tank 3 At the top, the second semicircle rotates around the connecting shaft of the two semicircles. A through hole is set on the second semicircle. The through hole is used to install the first pressure relief valve 1 and the pressure gauge. The inner bottom of the oil storage tank 3 is provided with a heating rod. An ignition electrode is arranged on the inner wall of the oil tank 3 .

Embodiment 2

[0032] The fire simulation experiment platform of the oil storage tank area in this embodiment is used to simulate the fire cyclone of the oil storage tank. The simulation experiment platform in this embodiment, the structural device diagram is as follows figure 2 As shown, a rotating device 5 is installed below the oil storage tank 3, the oil storage tank 3 is set to be open, an ignition electrode is arranged on the inner wall of the oil storage tank 3, and the rotating device 5 is connected to the motor.

[0033] The rotating device 5 is a rotatable circular turntable. The rotation of the circular turntable is controlled by the motor, and then the oil storage tank 3 is driven to rotate. At the beginning of the experiment, the fuel is ignited. After the combustion is stable, the rotating device 5 is started to observe the experimental phenomenon.

[0034] After a fire occurs in the 3rd area of ​​the oil storage tank, it is easy to cause multi-tank combustion, the number of f...

Embodiment 3

[0036] The fire simulation experiment platform in an oil storage tank area described in this embodiment is used to simulate a flowing combustion fire in an oil storage tank. The simulation experiment platform in this embodiment has a schematic structural diagram such as image 3 shown. In this embodiment, the side wall of the oil storage tank 3 has a series of holes along the vertical direction, and an electric valve pipeline 6 is arranged outside each hole. The highest point of the oil pool is below the ground.

[0037] In this embodiment, a row of holes is opened along the vertical direction on one side of the oil storage tank 3, the number of which is 8, and the pipes are extended outward.

[0038] Before the simulation experiment, according to the fires that simulate different liquid level conditions, oil is injected into the oil storage tank 3 to the corresponding liquid level. During the experiment, a small oil pool was ignited, and a single or multiple electric valve...

Abstract

The invention discloses an oil storage tank area fire simulation experiment platform which comprises a causeway and a plurality of oil storage tanks arranged in the causeway, the tank top of at least one oil storage tank is composed of two semicircles with the same size, the two semicircles are movably connected, the first semicircle is fixed to the top of the oil storage tank, and the second semicircle rotates around a connecting shaft of the two semicircles. A through hole is formed in the second semicircle and used for installing a pressure release valve and a pressure gauge, and a heating rod is arranged at the bottom in the oil storage tank. The physical fire experiment platform is built, oil storage tank fire accident types generated by different pre-combustion time and different factors are simulated and analyzed, fire accident characteristics and fire extinguishing difficulties are summarized and analyzed according to simulation results of the experiment platform, the reproduced oil storage tank fire accidents are real and reliable, and the experiment platform has high practical value. Good practicability is realized in the aspect of fire-fighting research.

Description

technical field [0001] The invention relates to the field of oil storage tank fire safety, in particular to a fire simulation experiment platform in an oil storage tank area. Background technique [0002] The oil storage tank stores a large amount of flammable and explosive dangerous goods. Once the oil tank bursts and burns, it will bring huge damage to the surrounding environment and facilities. The oil storage tank will not only boil over, splash and explode, but also under the thermal radiation impact of the high temperature flame of the fire tank, the structure of the adjacent oil storage tank will be damaged, and the strong radiation effect of the flame may cause the tank to burst and combustible steam Leakage affects the safety of adjacent oil storage tanks. Once the adjacent tanks explode and catch fire, a chain reaction often occurs, causing more violent fires. [0003] According to the working conditions of the oil storage tank, build a physical fire test platform...
