Technical Field

The invention relates to the technical field of oil pool fire combustion and fire safety, in particular to a multi-scale circular oil pool fire array experimental device capable of maintaining stable combustion.

Background

oil pool fire array combustion is commonly found in urban and industrial fires, and extremely fire behaviors such as flame combination, fire whirlwind and the like are possibly caused, so that the fire hazard and the complexity are obviously increased. The experimental research of the oil pool fire array combustion is developed, and the method has important scientific and application values for preventing and dealing with the fire hazard.

Typical oil pool fire combustion includes four stages of ignition, development, stabilization and extinction, with the stabilization stage being the focus of much research attention. Whether the pool flame can reach a plateau without fuel replenishment is closely related to the burn rate. At different combustion stages, the change of the fuel liquid level can affect the heat feedback and the air flow to different degrees, and further affect the combustion characteristics such as the combustion rate. In particular, significant changes in the level often affect the stability of the combustion, increasing the difficulty and uncertainty of the measurement.

in order to solve the problems, a method for continuously supplying oil to maintain the liquid level height is widely adopted in the conventional oil pool fire experiment device. Specifically, a connecting device is usually used to connect the oil pan and the oil supply system, and the liquid level is determined by visual inspection, thermocouple measurement, or a liquid level sensor. The oil supply mode of the device is usually manual or semi-automatic, can maintain stable combustion of a single oil pool fire to a certain degree, but has certain limitation on the oil pool fire array.

On the one hand, the combustion process of an oil sump fire array depends on the oil pan size, oil pan spacing, and fuel type. These factors can cause complex changes in combustion characteristics under flame interaction. The existing device cannot accurately control the influence factors and carry out system experiments, and the experimental requirements under different scale working conditions are difficult to be considered. On the other hand, the interaction of flames can cause the complex nonlinear change of the instantaneous combustion rate, the existing oil supply device can not realize automatic oil supply according to the requirement, the too fast and too slow oil supply can influence the heat convection in the fuel of the oil pool, or cause larger local liquid level height fluctuation, and further increase the instability and the measurement error of combustion.

The oil supply pipeline is provided with a one-way valve.

wherein the burning rate is recorded by the electronic balance 303 of the liquid level stabilizing device; the temperature is measured by a thermocouple 109 array, and a hard thick metal wire can be inserted into the test platform chute 104 to assist in fixing and reduce the influence on the flame flow field; the heat flux can be measured using heat flow meter 108, whose wire wrapped aluminum foil can pass from chute 104 to avoid exposure to an open flame; the flame profile may be obtained by processing video images captured by the camera 107.

in the specific implementation:

as shown in fig. 1, the test platform 100 for the present experiment had dimensions of 5m long × 5m wide × 1m high, and 9 stainless steel circular oil pans 101 of identical size (20 cm in diameter, 3cm in height) were arranged in a two-turn array, with the eight oil pans 101 on the periphery constituting a regular octagon to be as close to a circle as possible. The threads on the bottom of the oil pan 101 are sealingly connected to a metal tube 102 at the bottom of the test platform, which is further connected to a rubber tube 103. The effect of the change in the oil pan 101 interval ranging from 20cm to 140cm was studied in this experiment, and for this purpose, the oil pan 101 was moved along the chute 104 and positioned to a preset oil pan interval in conjunction with the mesh plate 105, and the remaining space of the chute 104 was sealed with the chute block 106 in cooperation with aluminum foil, fire-proof mud, and the like, as shown in fig. 2. After that, an image pickup device, i.e., a camera 107 is set up to determine a good photographing angle, and a heat flow meter 108 and thermocouples 109 in an array are fixed. Thereafter, automatic injection of the liquid fuel 110 into the oil pan 101 may begin.

as shown in fig. 3, 4 and 5, the oil pan 101 may have various shapes, such as a circular oil pan, a square oil pan and a rectangular oil pan, in which the circular oil pan is selected as an example in the present experiment. For oil pans with other shapes, the oil pan can be replaced in the test platform 100 according to experimental needs, and only the bottom of the oil pan 101 and the threads of the metal pipe 102 need to be loosened in a rotating mode.

After the oil pan array was secured, the preset fuel level was further determined and experiments were conducted. Siphon tube 300 is made of a transparent material, and siphon tube 300 is inserted into a fuel-filled tank 301, and at this time, tank 301 is sealed except for the top of siphon tube 300. As shown in fig. 6, the fuel supply device replenishes the liquid surface stabilizing device with fuel by an oil pump before and after the experiment as needed, and the hole plug at the top of the oil reservoir tank 301 is sealed during the experiment. The valve provided in the oil supply line is a stop valve 302, and when the stop valve 302 is opened, the oil storage tank 301 starts to deliver fuel to the oil pan 101 until the liquid levels of the oil pan 101 and the oil storage tank 301 reach a static pressure balance. When the electronic balance 303 is turned on, the liquid level heights of the oil tank 301 and the siphon tube 300 can be determined by the liquid level scale 304, and the liquid level of the oil tank 301 can be determined by observing the liquid level scale 304.

After the above preparation is completed and measuring instruments such as the thermocouple 109 and the heat flow meter 108 are laid out, the ignition is started. The fuel level in the oil pan 101 will drop due to combustion consumption, which will create a head with the fuel in the storage tank 301 and thus a static pressure difference. Since the reservoir 301 is sealed elsewhere, the pressure differential will draw ambient air in from the siphon tube. The incoming air will push the air above the tank fuel in the storage tank 301 and create air pressure that drives the fuel in the tank from the shut-off valve 302 to the oil pan 101 until the oil pan 101 level is again at a hydrostatic equilibrium with the storage tank 301. This process is automated and the static pressure difference is the driving force for the fuel flow. It is apparent that when the pipe diameter of the siphon tube 300 is appropriate, the burning rate (fuel consumption rate) and the oil supply (oil replenishment) rate are automatically matched, the pipe diameter depending on the capacity of the oil reservoir 301. In this example, the tank used was 15cm in diameter and 100cm in height, corresponding to a siphon 300 of 1cm in diameter.

after the combustion process and measurement are completed, the stop valve 302 of the oil storage tank 301 may be closed, the oil supply may be stopped, and the remaining fuel in the oil pan 101 may be burned out. After sufficient cooling, the next set of experiments can be set up. Before the experiment, the hole plug at the top of the oil storage tank 301 is opened, the insertion end of the oil delivery conduit 307 is inserted, the insertion section of the oil delivery conduit 307 is the rubber pipe 305, the oil delivery conduit 307 communicated with the liquid pump 306 is inserted into the fuel supply pool cavity 308 in the fuel supply pool 309, the switch of the liquid pump 306 is opened, fuel is pumped from the liquid fuel supply pool 309 to supplement the oil storage tank 301, then the rubber pipe 305 and the liquid pump 306 are removed, and the hole plug at the top of the oil storage tank 301 is closed. The foregoing experimental procedure may then be repeated.

As shown in fig. 7 and 8, the oil pan 101 is shown in an array of two and three circles in a circular array, wherein the two-circle array was selected as an example in this experiment. For an array of three or more oil pans, the oil pan can be added to the test platform 100 according to the needs of the experiment, and the corresponding oil storage tank 301 and oil supply pipeline can be replaced or added, and the experiment operation process is similar.

The multi-scale round oil pool fire array experimental device capable of maintaining stable combustion provided by the embodiment of the invention mainly comprises a test platform 100, an oil pan 101 array, a liquid level stabilizing device, a fuel supply device, an oil supply loop and a measuring device. The test platform 100 includes a fire resistant platform, a grid plate 105, a chute 104, and a chute block 106 that accurately controls the array position of the oil pan 101. The oil pan 101 is adjustable in size and shape, and the bottom opening is in threaded sealing connection with the oil supply pipe. The liquid level stabilizing device comprises an oil storage tank 301, a siphon tube 300, a stop valve 302, a liquid level scale 304 and an electronic balance 303, and can stably supply oil to the oil pan 101 and maintain the liquid level height. The fuel supply device can continuously supply oil to the liquid level stabilizing device. The oil supply loop can resist high temperature and chemical corrosion.
