An external storage pressure type perfluorinated hexanone fine water mist combined fire extinguishing and cooling system

Abstract

The present invention relates to an external storage pressure type perfluoromethylcyclohexanone fine water mist combined fire extinguishing and cooling system, which includes a nitrogen starting bottle group, a nitrogen driving bottle group, a perfluoromethylcyclohexanone tank, a water storage tank, a pipeline group, a nozzle and a control component. When thermal runaway occurs, the detector detects the fire information and feeds it back to the control component. The control component starts the nitrogen starting bottle group. The nitrogen starting bottle group releases pressurized nitrogen to start two nitrogen driving bottle groups. The nitrogen driving bottle groups release high-pressure nitrogen and deliver it to the perfluoromethylcyclohexanone tank. The perfluoromethylcyclohexanone is released into the third connecting pipe after being pressurized and is sprayed through the nozzle. After the perfluoromethylcyclohexanone agent is sprayed out, the control component closes the spraying port of the perfluoromethylcyclohexanone tank. After the perfluoromethylcyclohexanone in the protected area is impregnated and delayed, the control component controls the high-pressure nitrogen to pass through the water storage tank, and the water in the water storage tank flows from the third connecting pipe through the nozzle, so that the nozzle sprays at the fine water mist spraying hole to form micro water mist droplets, thereby cooling the protected area.

Description

Technical Field

[0001] The present invention belongs to the technical field of fire-fighting equipment, and particularly relates to an externally stored-pressure perfluoromethylcyclohexanone fine water mist combined fire extinguishing and cooling system. Background Art

[0002] Currently, the main problem to be solved in battery fires is the temperature reduction problem. Once the temperature drops, the battery will stop burning. Currently, perfluoromethylcyclohexanone has a good fire extinguishing effect, but the fire extinguishing and impregnation time are short, and it cannot prevent the continuous development of thermal runaway. Fine water mist has a good temperature reduction effect, but the effect of extinguishing battery fires is not good. In view of this, the present solution is thus developed. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an externally stored-pressure perfluoromethylcyclohexanone fine water mist combined fire extinguishing and cooling system, which can rapidly reduce the temperature after flame retardancy.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: an externally stored-pressure perfluoromethylcyclohexanone fine water mist combined fire extinguishing and cooling system, including a nitrogen starting bottle group, a nitrogen driving bottle group, a perfluoromethylcyclohexanone tank, a water storage tank, a pipeline group, a nozzle and a control component. The pipeline group includes a plurality of first connecting pipes, second connecting pipes and multiple third connecting pipes. The nitrogen starting bottle group and the nitrogen driving bottle group are connected through the first connecting pipe. The nitrogen driving bottle group is connected to the perfluoromethylcyclohexanone tank through the first connecting pipe. The output ends of the perfluoromethylcyclohexanone tank and the water storage tank are connected to the second connecting pipe. The second connecting pipe is connected to the third connecting pipe. The third connecting pipe is connected to the nozzle. The control component is used to drive the nitrogen starting bottle group, the nitrogen driving bottle group, the perfluoromethylcyclohexanone tank and the water storage tank to operate. The nozzle has fine water mist spraying holes.

[0005] Further, a pressure reducing and stabilizing valve is arranged between the nitrogen driving bottle group and the perfluoromethylcyclohexanone tank.

[0006] Further, the fire extinguishing and cooling system further includes a smoke detector and a temperature detector, and the smoke detector and the temperature detector are installed in the protection area and electrically connected to the control component.

[0007] Further, the pipeline group further includes a fourth connecting pipe, and the perfluoromethylcyclohexanone tank and the water storage pipe are connected through the fourth connecting pipe. A pilot-operated opening valve is arranged on the fourth connecting pipe.

[0008] Further, a filter is arranged between the second connecting pipe and the third connecting pipe.

[0009] Further, check valves are arranged at the output ends of the perfluoromethylcyclohexanone tank and the water storage tank and the second connecting pipe.

[0010] Further, the pipe group further includes an outer sleeve, the outer sleeve is sleeved on the third communication pipe, through holes are provided on the outer sleeve, the spray head extends out of the through holes, the outer sleeve is communicated with the water storage tank, and spray holes are provided on the outer sleeve.

[0011] Further, the spray holes are conical holes, and the side of the outer sleeve circumference where the spray holes are located is the small diameter.

[0012] Further, PVC fillers are provided in the spray holes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When thermal runaway occurs during the application of the present invention, the detector detects the fire information and feeds it back to the control component. The control component starts the nitrogen starting bottle group. The nitrogen starting bottle group releases pressurized nitrogen to start two nitrogen driving bottle groups. The nitrogen driving bottle groups release high-pressure nitrogen and transport it to the perfluoromethylcyclohexanone tank. After being pressurized, perfluoromethylcyclohexanone is released into the third communication pipe and sprayed through the spray head. After the perfluoromethylcyclohexanone agent is sprayed out, the control component closes the spray port of the perfluoromethylcyclohexanone tank. After the perfluoromethylcyclohexanone in the protected area is impregnated and delayed, the control component controls the high-pressure nitrogen to pass through the water storage tank, and the water in the water storage tank flows through the third communication pipe and the spray head, so that the spray head sprays at the fine water mist spray holes, forming micro water mist droplets to cool down the protected area.

[0015] 2. The pipe group further includes an outer sleeve, the outer sleeve is sleeved on the third communication pipe, and the outer sleeve is communicated with the water storage tank. When thermal runaway occurs and the water storage tank is started, water will fill the third communication pipe and spray out from the spray head, and fill the space between the outer sleeve and the third communication pipe. When the protected area is only in the initial stage of thermal runaway and the temperature has not risen sharply, the PVC fillers on the outer sleeve will not be melted, and only perfluoromethylcyclohexane and fine water mist are needed for fire extinguishing and cooling. When the temperature rises above 150 degrees Celsius, at this time, it is necessary to cool down the protected area. In addition to the fine water mist cooling, the PVC fillers will be melted, and high-pressure water will be sprayed out from the spray holes for auxiliary cooling. Description of the Drawings

[0021] As Figures 1-3 shown, this embodiment provides an externally stored pressure type perfluorohexanone fine water mist combined fire extinguishing and cooling system, including a nitrogen starting bottle group 1, a nitrogen driving bottle group 2, a perfluorohexanone tank 3, a water storage tank 4, a pipeline group 5, a sprinkler head 6, a smoke detector 7, a temperature detector 8, a detection component and a control component.

[0022] The smoke detector 7 and the temperature detector 8 are installed in the protected area and electrically connected to the control component. A fire alarm and a manual control button are also installed in the protected area. The pipeline group 5 includes a plurality of first connecting pipes 51, second connecting pipes 52, a plurality of third connecting pipes 53, a fourth connecting pipe 54 and an outer sleeve 55.

[0023] The nitrogen starting bottle group 1 and the nitrogen driving bottle group 2 are connected through the first connecting pipe 51. The nitrogen driving bottle group 2 is connected with the perfluorocyclohexanone tank 3 through the first connecting pipe 51. Two pressure reducing and stabilizing valves 21 are arranged between the nitrogen driving bottle group 2 and the perfluorocyclohexanone tank 3. The output ends of the perfluorocyclohexanone tank 3 and the water storage tank 4 are connected with the second connecting pipe 52. Check valves are arranged between the output ends of the perfluorocyclohexanone tank 3 and the water storage tank 4 and the second connecting pipe 52. The perfluorocyclohexanone tank 3 and the water storage pipe are connected through the fourth connecting pipe 54. A pilot-operated opening valve 31 is arranged on the fourth connecting pipe 54. The second connecting pipe 52 is connected with multiple third connecting pipes 53. A filter 521 is arranged between the second connecting pipe 52 and the third connecting pipes 53. Selection valves 531 are respectively arranged on the multiple third connecting pipes 53. The selection valve 531 on the third connecting pipe 53 corresponding to the protected area where a fire occurs is opened. The third connecting pipe 53 is connected with the spray head 6. The spray head 6 has a fine water mist spraying hole and a through hole. The fine water mist spraying hole and the through hole are switched by an inner guide valve core. An outer sleeve 55 is sleeved on the third connecting pipe 53. The outer sleeve 55 and the third connecting pipe 53 form a sealed chamber. Through holes are arranged on the outer sleeve 55. The spray head 6 extends out of the through hole. The outer sleeve 55 is connected with the water storage tank 4. Specifically, the outer sleeve 55 and the third connecting pipe 53 are connected through a fifth connecting pipe 56. An electromagnetic valve is arranged on the fifth connecting pipe 56. When the pilot-operated opening valve 31 is started to be connected, the electromagnetic valve is also started. Spraying holes are arranged on the outer sleeve 55. The spraying holes face the protected area. The spraying holes are conical holes. The side of the outer peripheral surface of the outer sleeve 55 where the spraying holes are located is the small diameter. PVC fillers 551 are arranged in the spraying holes.

[0024] The detection component includes a pressure display meter and a liquid level measurement component. The pressure display meter is installed on the nitrogen driving bottle group 2 and is electrically connected with the control component. The liquid level measurement component is installed on the pipes of the perfluorocyclohexanone tank 3 and the water storage tank 4 and is electrically connected with the control component to ensure the stable operation of each component.

[0025] The control component is used to drive the nitrogen starting bottle group 1, the nitrogen driving bottle group 2, the perfluorocyclohexanone tank 3 and the water storage tank 4 to operate. The spray head 6 has a fine water mist spraying hole.

[0026] When thermal runaway occurs, the smoke detector 7 and the temperature detector 8 detect the fire information and feedback it to the control component. The control component activates the nitrogen starting bottle group 1. The nitrogen starting bottle group 1 releases pressurized nitrogen to start two nitrogen driving bottle groups 2. The nitrogen driving bottle groups 2 release high-pressure nitrogen, which is delivered to the perfluorocyclohexanone tank 3 after being depressurized and stabilized in two stages by two pressure reducing and regulating valves. The perfluorocyclohexanone is released into the third connecting pipe 53 after being pressurized and is sprayed through the nozzle 6. After the perfluorocyclohexanone agent is sprayed out, the control component closes the spraying port of the perfluorocyclohexanone tank 3. After the perfluorocyclohexanone in the protected area is impregnated and delayed, the control component controls the pilot-operated opening valve 31 to open. The high-pressure nitrogen passes through the pilot-operated opening valve 31 and the water storage tank 4. The water in the water storage tank 4 flows through the third connecting pipe 53 and the nozzle 6. When the water storage tank 4 is activated, the water will fill the third connecting pipe 53 and spray out from the nozzle 6. At the same time, the water in the water storage tank 4 will also flow into the fifth connecting pipe 56 to fill the space between the outer sleeve 55 and the third connecting pipe 53. When the protected area is only in the initial stage of thermal runaway and the temperature has not risen sharply, the PVC filler 551 on the outer sleeve 55 will not be melted, and only perfluorocyclohexanone and fine water mist are needed to extinguish the fire and reduce the temperature. When the temperature rises above 150 degrees Celsius, at this time, it is necessary to cool down the protected area. In addition to cooling with fine water mist, the PVC filler 551 will be melted, and high-pressure water will spray out from the water spraying holes for auxiliary cooling.
