Problems solved by technology
The reason why the device is difficult to use is that the fire extinguishing effect is insufficient, also only 45 g / m 3 , the temperature of the aerosol jet at 0.3 m from the nozzle of the device is too high and plaster is also used

Embodiment Construction
[0024] The present invention will be further explained below in conjunction with the accompanying drawings. The structure and principle of this device are very clear to those in the field. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0025] The aerosol fire extinguishing device includes: a shell 11, which is connected to each other by two disk-shaped half shells 1 by curling edges 2. There is an intermittent gap between the curling edge 2, and the gap shape is a radial tube nozzle, which can ensure the spraying of aerosol mixture; one of the radial tube nozzles is equipped with an activation component 4, and each half shell 1 is equipped with There is a pyrotechnic charge 5, which is fixed on the wall of the half shell 1 and fixed by a load-bearing insulation layer 6, and there is a free space 7 between the two ends of the pyrotechnic charge 5. At this time, the di...

The invention belongs to a fire protection technology, and particularly belongs to aerosol mixture generation equipment for inhibiting combustion and a fabrication method of the aerosol mixture generation equipment for carrying out total flooding extinguishing on fixed devices in a burning place or a sealed field. Gaps between turned edges of aerosol extinguishing equipment are radial tubular nozzles which are evenly arranged and 5-8mm in diameter. The ratio of the total burning area of a grain end face to the total area of the sections of the tubular nozzles is within an interval of 65-90; the attached turned edges are arranged among the nozzles, and the turned edges and the nozzles are for fastened by fixing elements. The radial tubular nozzles evenly distributed between the turned edges of the equipment, the total burning area of the grain surface and the total area of the sections of the tubular nozzles form a certain relationship, so that the fire extinguishing performance of the equipment does not exceed 28g / cm<3>, and meanwhile, the temperature of an aerosol jet flow region at the place of which the nozzle is greater than 0.3m is reduced by adopting the comprehensive characteristics due to the fixed diameters of holes of the nozzles.
Description
[Technical Field] [0001] The invention belongs to fire fighting technology, in particular to a generating device that produces a combustion-inhibited aerosol mixture. [Background technique] [0002] In the field of fire fighting technology, the well-known fire extinguishing equipment mainly includes the patented technology of the aerosol fire extinguishing device that is thrown to the burning place or is fixedly installed in the protective field. For example, the Russian patent: No. 2403930, No. 2256474, No. .2237503 and so on. [0003] Some well-known aerosol fire extinguishing devices have thrown or fixed functions. [0004] Known aerosol fire extinguishing devices, such as the Russian patent number №34383, кл.А62С3 / 00 published in 2003, are composed of two relatively connected disc-shaped containers with crimped edges. The gap is the outlet spout, equipped with foamed plastic pads, the pyrotechnic charge is fixed in two containers through the building gypsum insulation layer, an...
