Description
Technical field
The utility model belongs to fire prevention field, relates in particular to a kind of suspension type water smoke extinguishing device.
Background technology
Micro-water smoke drips popular name and is again thin water smoke, in " micro-water smoke drips fire-extinguishing apparatus authentication techniques specification " CNCA/CTS0013-2010, specifies, micro-water smoke drips for diameter Dv0.50 is less than the water smoke that 200 μ m and DV0.99 be less than 400 μ m and drips.
Thin water smoke technology is a kind ofly to have that non-environmental-pollution, water consumption are low, technology to the destructive feature such as little of protection object, thereby has caused that people are to using thin water smoke to substitute the concern of alkyl halide series extinguishing chemical.Generally acknowledged Mechanism of Water Mist Fire Extinction is: because the total surface area of water after atomization greatly increases, water is vaporized rapidly, can suppress the generation of fire and spread from three aspects: first, and combustion reaction that the latent heat of vaporization of evaporation process absorption is cooling; Secondly the heat absorption barrier that, highdensity water smoke and evaporation process produce can interdict the radiant heat transmission in flame; Its three, the expansion of steam volume in evaporation process (for 1700 times of water) is to effective dilution of oxygen concentration combustion reaction that suffocated.Therefore, fine water mist fire-extinguishing system with respect to conventional water sprinkler system (cumulative integral average diameter Dv0.9 > 1000 μ m) have water consumption obviously reduce, act on rapidly, to advantages such as indoor equipment goods and materials pollution level are little.With respect to halo alkanes fire extinguishing system, there is environmental friendliness, the outstanding feature such as non ozone depleting and greenhouse effects, and when fire extinguishing, there is no the γ-ray emission of toxic and side effect, harmless, thin water smoke also has can suppress or absorb flue dust, reduces environment temperature, is escape and the benefit gaining time of putting out a fire.
At present, fine water mist fire-extinguishing system is mainly divided into two large classes: single current medium fine water mist fire-extinguishing system and double-current medium fine water mist fire-extinguishing system.Wherein single current medium fine water mist fire-extinguishing system is made up of high-pressure hydraulic pump, control valve, shower nozzle, pipeline and detection system, and its shortcoming is high, the difficult installation of equipment complexity, cost, will make whole system ineffective as long as there is a position to break down.Double fluid medium fine water mist fire-extinguishing system utilizes gases at high pressure in nozzle, to impact water smoke to reach the object of assisted atomization.The atomization quality of double fluid medium atomization system is generally better, but shortcoming is that driving gas energy input is larger, generally adopts gas-liquid to be separately stored in different steel cylinders, article two, Pipeline transport, control system is more complicated, and therefore system cost is high, use is inconvenient, and reliability is also poor.
Powder extinguishing agent is also increasingly extensive in the application in security against fire field, and it is the fine particle being mixed by fire extinguishing base-material and the appropriate raw material such as lubricant, anti-blushing agent.Suspension type reservoir pressure dry powder extinguishing installation comprises pressure vessel and automatic sprinkler, and powder extinguishing agent and nitrogen are housed in pressure vessel.Pressure vessel upper end outer surface is provided with suspension ring, can hang near of protected object.
When fire extinguishing, utilization is stored in the nitrogen with pressure of pressure vessel inside and extinguishing chemical is outwards sprayed, and the surface that covers comburant is to form the separation layer that hinders burning, absorb the free radical or the active group that in chemical reaction, produce simultaneously, thereby play the effect of Chemical Inhibition, so that the chemical chain reaction of burning is interrupted.The shortcoming of powder extinguishing agent is that cooling effect is poor, a therefore fire fire extinguishing successful less to scale, but be difficult to control spreading of fire, and cannot prevent the resume combustion of fire, so be difficult to meet the extinguishment requirement of large-scale industry fire or malignant fire.In addition, the phenomenons such as the finished product dry powder powder of refinement or fine easily occurs making moist in the process of storage, caking, will cause like this extinguishing property greatly to reduce, and after spurting, can cause secondary dust to pollute not environmental protection.
