Description
Technical field:
The present invention relates to a kind of vehicle-mounted extinguishing device, specifically a kind of vehicle mounted superfine spray fire extinguishing device.
Background technology:
Existing fire fighting vehicle generally adopts extinguishing chemicals such as water, foam solution, dry powder to be transported to spray gun or big gun by the single tube road, the extinguishing chemical that ejects becomes the nature physical state, that is: water becomes water column or spray water, foam solution becomes natural shaped regular-type foam by contacting with atmosphere, dry powder is directly injected to the scene of fire, thereby a large amount of extinguishing chemicals directly is scattering into ground and does not participate in fire extinguishing, its shortcoming is that fire-fighting efficiency is low, there is a large amount of residual water scene of fire, fire extinguishing back, water damage is serious, and a large amount of extinguishing chemicals does not participate in fire extinguishing and slatterned.Therefore, if extinguishing chemical is injected into the comburant surface with particle and small mist attitude thereof, can solve above-mentioned drawback.In view of narration of the present invention needs, set forth several nouns earlier, under the minimal design operating pressure, on the plane of one meter of spout, when recording water smoke the water mean particle dia of thick part is greater than 1000 μ, be referred to as spray water; The water mean particle dia is referred to as thin water smoke when 1000 μ to 200 μ, and the water mean particle dia is when being not more than 200 μ, be referred to as superfine spray, the fire-fighting efficiency of superfine spray is greater than thin water smoke, and the fire-fighting efficiency of thin water smoke is greater than spray water, and the fire-fighting efficiency of spray water is greater than common water droplet.Its extinguishing mechanism is: when adopting superfine spray as firing-fighting medium, the water droplet of its same relatively quality, spray water, thin water smoke, increased the surface area of unit volume particulate, carry out heat absorption easilier, the cooling combustion reaction, superfine spray is as the easier gasification of water particulate that absorbs heat, gasification back volume increases about 1700 times, because the generation of water vapour, both diluted near the oxygen concentration of flame, heat radiation has also been controlled in the combustion reaction that suffocated effectively, superfine spray is the extinguishing chemical of kind of cleaning, and has and cool off efficiently and the effect of suffocating.But the superfine spray fire extinguishing has technological difficulties, be exactly the problem that how superfine spray is ejected at a distance the scene of fire, because superfine spray water mean particle dia is little, himself sprays resistance in air big, can't satisfy the requirement of remote fire extinguishing, this technical barrier is successfully solved always.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of vehicle mounted superfine spray fire extinguishing device, with compressed air is carrier, water or water are become superfine spray or fine foam bubble with mixed liquor high-speed cutting in injection apparatus of foam, and be injected into the comburant surface at a high speed, at a distance through the spraying canister of science design, to reach the purpose of efficient, environmental protection, remote fire extinguishing.
Technical solution problem of the present invention adopts following technical scheme:
Vehicle mounted superfine spray fire extinguishing device, its feature is being to be carrier with the fire fighting truck, adopt " water-gas " dual circuit induction system, described air pipe comprises the tracheal pressure road of an air compressor and conveying gases at high pressure, described water lines comprises a water pump and the press water pipeline of the conveying water under high pressure that is communicated with exit of pump, described tracheal pressure road and press water pipeline converge in injection apparatus, and water under high pressure penetrates through spraying canister with the superfine spray shape after the high pressure gas cutting in injection apparatus.
The forced draft road of described injection apparatus and spraying canister junction is a tapered runner, the press water runner is the annular channel around described tapered runner, water under high pressure converges in the exit and the high pressure gas of tapered runner, and water under high pressure ejects through spraying canister with the superfine spray shape through the high pressure gas cutting.
Tracheal pressure road in the described injection apparatus and press water pipeline are opened and are closed by the ball valve control of synchronous working.
Described spraying canister from the porch to the interior shape in exit be first convergence back diffusion type.
Described press water pipeline is upper also to be communicated with the foam pipeline of controlling through valve in pump outlet, and this foam pipe head is communicated with foam tank.
On described tracheal pressure road and press water pipeline, be provided with flow and take into account check valve.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention adopts " water-gas " dual circuit induction system, tracheal pressure road and the press water pipeline tapered runner exit in injection apparatus is converged, water under high pressure penetrates through spraying canister with the superfine spray shape after the high pressure gas cutting, and its fire-fighting efficiency is much larger than spray water or thin water smoke.
2, the gases at high pressure runner of injection apparatus of the present invention and spraying canister junction is a tapered runner, gases at high pressure expulsion pressure is herein further strengthened, simultaneously, the water under high pressure runner is the annular channel around described tapered runner, be that water under high pressure converges with it around high pressure gas, water is slit into superfine spray by autogenous cutting to greatest extent, makes the water mean particle dia that ejects reduce to minimum, also is that atomizing effect reaches the best.
3, spraying canister of the present invention inside from the porch to the interior shape in exit be convergence back diffusion type earlier, more meet aeronautical dynamics and fluid machinery and learn principle, the range maximization of the superfine spray that ejects can be satisfied the demand of remote fire extinguishing.
Also being provided with the foam pipeline through valve control in the 4 press water pipelines of the present invention, therefore, is carrier with gases at high pressure, " water-foam " mixed liquor can be injected into the comburant surface with the superfine spray shape, has further improved fire-fighting efficiency.
5, because of the present invention adopts superfine spray fire extinguishing, in fire extinguishing procedure, most of water all evaporates or is dipped in the comburant and gone, and unburned thing (as the product in clothing, electrical equipment, warehouse etc.) is not had big soak and damage.
