It is characterized in that the top layer of the storage tank 1 is a water tank, and the bottom layer is empty; the tank top burner 2 is installed in the tank top water tank, immersed in water, and a short tank top burner nozzle 25 is arranged above it; the tank wall burner 7 is a standpipe vertically installed along the tank wall, the top is a semicircle across the top wall of the tank, and its back is opened at the position of the tank wall; the tank bottom burner 23 is installed in the tank bottom combustion groove 8; the igniter 22 is installed On the top wall of the storage tank 1 and above the combustion tank 8 at the bottom of the tank.

The inlet end of the manifold 13 is connected to the gas pipeline 15 and the gas-supporting pipeline 16, and the gas outlet is connected to the tank top burner pipeline 21, the tank wall burner pipeline 10, and the tank bottom burner pipeline 9. mixed at the place, and enter the respective burners for combustion through different burner pipelines; the control valves 14 and 17 on the gas pipeline 15 and the assisted gas pipeline 16 are adjusted by the control system to the ratio of gas and assisted gas, and the color of the flame is changed. When the ratio of propane and air is When the gas mixture is 4:1, a red-yellow flame of organic combustion can be obtained.

The combustion tank 8 at the bottom of the tank can be a water tank whose upper part is a solid support grid, or a tank for placing stones, and the bottom of the tank is provided with a drain port 23 .

The shape of the tank top burner 2 is a semicircle, a circle and arcs with different arc lengths.

The pipeline 21 of the tank top burner is in an inverted U shape, and the highest position is higher than the height of the storage tank, which can prevent the water in the storage tank from flowing back into the pipeline 21 .

The storage tank 1 can be constructed according to the proportion of the actual size of the storage tank. The material of the fire site is made of refractory materials, such as Corten steel, or materials processed by special processes. The height of the top layer of the storage tank is 1 meter. The storage tank can also be equipped with The spiral ladder, the maintenance platform and the cooling sprayer 6, build fire embankments and drainage ditches around the storage tank; the cooling sprayer is provided with nozzles connected to the cooling water pipeline, and the cooling water spraying is started when the device is running.

When the continuous immersion time of the fire extinguishing agent reaches the requirements of the control system, the fire is extinguished, otherwise the fire will re-ignite . The quantity and the position of fire extinguishing agent detector 3 can be set according to storage tank size and burner shape and size.

When the continuous immersion time of the fire extinguisher is sufficient, the flame detector detects that there is no flame, or the temperature sensor 5 detects that the fire site has been cooled to a certain temperature, the control system automatically closes the control valve of the burner in the corresponding area.

The working process of the utility model is: open the water inlet valve 19, water enters the top of the storage tank 1 until the burner 2 is submerged, and closes the water inlet valve 19. The control system opens the gas control valve 15 and the assisted gas control valve 16 to adjust the ratio and quantity of combustible gas and air. The gas and assisted gas are mixed at the manifold 13 to form a mixed gas, and the mixed gas passes through the tank top burner pipeline 21 and enters the tank top The burner 2, sprayed from the nozzle 25, passes through the water layer to reach the water surface. The control system activates the tank top fire device 24 to ignite the mixed gas on the water surface to form a tank top fire.

According to the fire data in the fire database, after a period of time, the control system opens the control valves 11 and 12, the gas mixture reaches the tank wall burner 7 and the tank bottom burner 22 through the pipeline, and the control system starts the tank bottom igniter 24 to ignite the tank wall burner. The gas of device 7 and tank bottom burner 22 forms the fire that simulation liquid flows to ground along tank wall from top to bottom.

During the fire extinguishing training process, the control system simulates the different development stages of the boiling over fire of the storage tank according to the fire data in the storage tank fire database. Adjust the fire intensity, and display the combustible gas concentration, flame state, temperature, and fire extinguishing agent usage in real time.

When the continuous immersion time of the fire extinguishing agent is sufficient, the flame detector detects that the flame does not exist, or the temperature sensor 4 detects that the fire scene is cooled to a certain temperature, the control system automatically closes the control valve of the burner in the corresponding area, and the fire is completely extinguished. If the parameters detected by each detector do not meet the preset requirements of the control system, the fire will re-ignite.
