The ABC powder extinguishing agent 3 that suspension type pulse dry powder automatic fire extinguisher of the present utility model is adopted comes from preferred to ABC dry powder constituent on the market and grain size proportion, the content of main composition ammonium dihydrogen phosphate (ADP) dry powder is 80% (± 3%), and its 90% particle diameter (being less than or equal to certain size particles mass percent is 90%) is 30 μ m.
Suspension type pulse dry powder automatic fire extinguisher of the present utility model has reached intended purposes by pattern testing identity device, pattern check 2006-3563, and the Interventions Requested name is called the total flooding extinguishing property, comprises category-A fire and category-B fire.
Be that example illustrates characteristics of the present utility model with the category-B fire fire-extinguishing test of being checked now, category-B fire standard-required is: should put out a fire at the extinguishing device AEI After End of Injection, and the fire in the food tray must not spill food tray.
Test one: dry powder quality is 1.1Kg, test space 2.0m * 2.0m * 2.5m, food tray size: 330mm * 330mm * 100mm, add 5L gasoline in the food tray, 4 diameters are the test tank of 75mm, high 120mm, bottom pad water, gasoline high 50mm in top is apart from a jar mouthful 10mm.Pre-burning 30s manually boots extinguishing device, and device starts the time of back to fray-out of flame: food tray fire: 7s, and oil tank fire: 11s, 7s, 12s, 9s open door and window and ventilate, and not resume combustion is not fired gasoline in food tray and the little oil tank.
Test two: dry powder quality is 4.5Kg, test space 2.0m * 2.0m * 2.5m, food tray size: 330mm * 330mm * 100mm, add 5L gasoline in the food tray, 4 diameters are the test tank of 75mm, high 120mm, bottom pad water, gasoline high 50mm in top is apart from a jar mouthful 10mm.Pre-burning 30s manually boots extinguishing device, and device starts the time of back to fray-out of flame: food tray fire: 7s, and oil tank fire: 11s, 7s, 12s, 9s open door and window and ventilate, and not resume combustion is not fired gasoline in food tray and the little oil tank.
The dry powder consumption that proves suspension type pulse dry powder automatic fire extinguisher of the present utility model by above-mentioned check test is 110g~130g/m 3, than the about 300g/m of it domestic colleague's product 3Dry powder consumption (pattern check 2003-2059,0.33m 3The used ultra-fine dry powder loadings in space is 108.3g) saved cost, fire-fighting efficiency significantly improves.
The course of work of suspension type pulse dry powder automatic fire extinguisher of the present utility model is as follows:
A. temperature-sensitive self-starting mode: the heat-sensitive line of spreading and branch and sleeve pipe 13, when the temperature of perception 〉=170 ℃, cause spontaneous combustion, and with the speed conduction of about 0.33m/s; Through the side circular hole of mounting bracket 12, through perforated bolt 8, be transmitted to gas generator propellant 6, the gas generating compositions 6 that ignites, moment produces flue gas, breaks through aluminium film 5, promotes powder extinguishing agent 3, breaks through sealed aluminum film 2 again, and dry powder 3 pulse high velocity jet are arrived protected district.
B. manual electric Starting mode: under some specific environment, the not perception of fire, heat-sensitive line having taken place, is not that heat-sensitive line is malfunctioning, but because the reason of environment, perhaps installation wiring (heat-sensitive line) is unreasonable, make the heat-sensitive line perception less than.At this moment will wait for automatic startup, the possible intensity of a fire is big.Fortunately device has manual electric Starting mode.During erecting device, with the two ends of electric initiator 10, by a commutator (or double-throw button), be connected on the DC24V power supply, when fire takes place, move commutator (or pressing the double-throw button), make the two ends of electric initiator 10 and DC24V power supply form the conducting loop.Gas generator propellant 6 is caused by the electric heating of electric initiator 10, and moment produces flue gas, breaks through aluminium film 5, promotes powder extinguishing agent 3, breaks through sealed aluminum film 2 again, and powder extinguishing agent 3 pulse high velocity jet are arrived protected district.
Above-described embodiment only is that the preferred implementation to suspension type pulse dry powder automatic fire extinguisher of the present utility model is described; be not that design of the present utility model and scope are limited; relate under the scheme prerequisite not breaking away from the utility model; various modification and improvement that those skilled in the art make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
