Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to an aerosol fire extinguishing and rapid cooling device. Background Art

[0002] Aerosol fire extinguishing devices can be divided into hot aerosol and cold aerosol according to the way aerosol is generated. Aerosol fire extinguishing devices used in domestic projects are all hot types. Cold aerosol fire extinguishing technology is still in the development stage and there are no formal products. Hot aerosol extinguishes fires based on the principles of negative catalysis and destruction of the combustion reaction chain. The cooling effect of hot aerosol fire extinguishing agents mainly relies on the endothermic decomposition of metal oxides and carbonates. The heat released by any fire in a short period of time is limited. If the solid particles in the aerosol can absorb part of the heat released by the fire source in a short period of time, the temperature of the flame will decrease, and the heat radiated to the combustion surface and used to crack the already vaporized combustible molecules into free radicals will be reduced, and the combustion reaction will be suppressed to a certain extent.

[0003] Traditional aerosol fire extinguishing devices are generally pressure storage type fire extinguishing devices. The fire extinguishing agent and driving gas in the bottle are mixed, which easily causes fire extinguishing agent deposition and leads to uneven spraying. In addition, the raw materials for making the bottles of pressure storage type fire extinguishing devices are all metals or metal alloys. This type of fire extinguishing device is generally bulky and not suitable for automotive or home use. In addition, the released fire extinguishing particles remain at the fire site, making it inconvenient to clean up. Utility Model Content

[0022] Working principle: When the temperature of the external ignition point is higher than the temperature set on the main board 33, the main board 33 sends a start signal to the controller 4, and the controller 4 controls the ejector 5 and the hot aerosol generator 6 to work. The hot aerosol generator 6 emits a large amount of gas when it is started. The gas enters the pipe 8 along the through hole 81, and is pushed upward by the ejector 5. Then, the gas passes through the through hole 81 and reacts with the fire extinguishing storage in the fire extinguishing composition storage tank 7 to produce effective fire extinguishing substances. The effective fire extinguishing substances are ejected upward along the pipe 8 from the ejection hole 21 corresponding to the position of the nozzle 9. The fire extinguishing composition sublimates, decomposes under heat, or absorbs heat from each other. Under the action of heat, the gasified metal ions such as Sr, K, Mg or cations that have lost electrons decomposed by the hot aerosol fire extinguishing agent exist in the form of steam and react with the active groups H in the combustion. + , - OH and O 2- Multiple chain reactions occur, and at the same time they are catalyzed to recompose stable molecules, thereby interrupting the branch chain reaction of the combustion process. This process is repeated, and the active groups in the combustion are consumed in large quantities, the concentration continues to decrease, and the combustion is suppressed to achieve the effect of extinguishing the fire.
