Abstract
The present invention relates to a fire-fighting vehicle mounted water mist fire-suppressing and smoke-removing equipment. It is characterized by that it uses the fire-fighting vehicle as carrier, on the fire-fighting vehicle an air barrel is set, in the air barrel interior an axial-flow blower is set; in the barrel mouth position of said air barrel, along the periphery of said air barrel a ring-shaped conduit is set, along said ring-shaped conduit uniformly distributed are water mist nozzles. Said invention integrates vehicle mounting, fire-fighting, ventilation, smoke-removing and dust-removing functions into one body, and can quickly eliminate smoke, lower temperature and remove dust.
Description
Technical field:
The present invention relates to the fire-fighting fire extinguishing fume extractor, the fire-fighting vehicle-mounted fire extinguishing fume extractor of more specifically saying so.
Background technology:
Use the air-supply fume extractor to have following effect at fire-extinguishing location:
1, powerful scene of a fire forced draft can change the flame combustion direction, helps protecting inflammable and explosive and emphasis place and zone.
2, the fire that takes place at industries such as oil, chemical industry can effectively dilute toxic and harmful, also can change the direction of filling the air of toxic and harmful according to different positions.
3, in the scene of fire in subway, tunnel, can be divided into zones of different to the intensity of a fire, be convenient to organize fire fighter's attack and cover retreat.
4, put out front and back in the scene of a fire, suitable air-supply can be avoided personnel's death by suffocation, rescue life.
About fine mist fire-fighting: the related definition of thin water smoke is under the minimal design operating pressure, on the plane of one meter in shower nozzle, record water smoke the water mean particle dia Dv0.99 of thick part be not more than 1000 μ.The extinguishing mechanism of thin water smoke is: when thin water smoke during as firing-fighting medium, the water droplet of its same relatively quality, increased the surface area of unit volume particulate, carried out heat absorption, cooling combustion reaction easilier.Thin water smoke is as the easier gasification of water particulate of absorption heat, and gasification back volume increases about 1700 times, because near the oxygen concentration of flame had both been diluted in the generation of water vapour, heat radiation has also been controlled in the combustion reaction that suffocated effectively.Thin water smoke is a kind of extinguishing chemical of cleaning, and has and cool off efficiently and the effect of suffocating, and as one of substitute products of halon fire agent, is widely used abroad from the nineties.In recent years, domestic units concerned were studied thin water smoke, but just limited to the fire extinguishing system that is installed in fixed-site, provided water for fire extinguishing by pipe network.
Obviously, air-supply smoke evacuation and fine mist fire-fighting are the two big important measures of suing and labouring that are applied in the scene of fire.But up to now, air-supply smoke evacuation and fine mist fire-fighting all are to bring into play function separately as independent equipment, and the subject matter that this mode exists comprises:
1, implementing smoke evacuation with air-supply merely can not make the visibility of scene of fire effectively be improved.
2, be installed in fixed field, utilize ductwork pressure that the fine spray extinguisher of water for fire extinguishing is provided, its active position is fixed, sphere of action is limited, can not bring into play its due effect.
Summary of the invention:
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of fire-fighting vehicle-mounted thin water mist fume extractor that integrates vehicle-mounted, puts out a fire, ventilates, discharges fume dedusting is provided, so that can eliminate smoke rapidly, cooling and dedusting, be convenient to personnel and enter the scene of a fire and carry out rescue.
The technical scheme that technical solution problem of the present invention is adopted is:
Design feature of the present invention is to be carrier with the fire fighting truck, vehicle-mounted air duct is set, in described air duct, axial flow blower is set, nozzle position at described air duct, along the air duct periphery ring-type water channel is set, along the ring-type water channel fine mist spray head that evenly distributes, each shower nozzle is obliquely installed, and the jet axis of each shower nozzle that is obliquely installed forms taper in air duct the place ahead.
It is one that the present invention collects fire extinguishing, illumination, ventilation and smoke evacuation dedusting, in the scene of a fire is rescued, also can close the water smoke valve as required, carries out the air feed of big discharge capacity separately, can eliminate smoke rapidly, lower the temperature, and dedusting is convenient to personnel and is entered scene of a fire implementation rescue.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is an onboard system, utilizes the powerful forced draft of axial flow blower, thin water smoke can be delivered to 60 meters with the interior scene of a fire, all can implement fire extinguishing to the naked light in this scope, has greatly widened the fire extinguishing scope of thin water smoke.
2, the present invention is applied in petrochemical industry fire and the toxic and harmful scene of fire, can fast and effeciently dilute toxic and harmful, avoids spreading.
3, the present invention is owing to adopt fine mist fire-fighting, and same scope fire fine mist fire-fighting is with 1/20 of clear water fire extinguishing institute water requirement, thus a large amount of water resource of saving.
4, the present invention is in conjunction with thin water smoke smoke evacuation, owing to the combination of the carbon particle in water mist particle and the flue gas precipitates, make the smog energy rapid precipitation in the scene of a fire, increase the visibility of scene of fire fast and effectively, be convenient to set up a play and cover retreat, the life that also can make the scene of fire is deposited because of the instant improvement of environment obtains prolonging.

Fig. 1 is an onboard system schematic diagram of the present invention.
Fig. 2 is an air duct profile schematic diagram of the present invention.
Fig. 3 is an air duct nozzle of the present invention position schematic diagram.
Fig. 4 is a fine mist spray head distributed architecture schematic diagram of the present invention.
Number in the figure: 1 fire fighting truck, 2 air ducts, 3 axial flow blowers, 4 ring-type water channels, 5 fine mist spray heads, the 6 entry mouths of pipe, 7 jet axis.
Below pass through the specific embodiment, and in conjunction with the accompanying drawings the present invention be further described:
The specific embodiment:
Referring to Fig. 1, present embodiment is to be carrier with fire fighting truck 1.
Referring to Fig. 1, Fig. 2 and Fig. 3,, vehicle-mounted air duct 2 is set at the afterbody of fire fighting truck 1, axial flow blower 3 is set in the air duct 2, at the nozzle position of air duct 2, along the periphery of air duct 2 ring-type water channel 4 is set, the entry mouth of pipe 6 of ring-type water channel 4 is positioned on the air duct lateral wall at place, ring-type water channel 4 positions.
Fig. 2, Fig. 3 and shown in Figure 4, along ring-type water channel 4 even distribution fine mist spray heads 5, each fine mist spray head 5 is obliquely installed, and the jet axis 7 of each fine mist spray head 5 that is obliquely installed forms taper in the place ahead of air duct 2.
In concrete the enforcement:
As calculated and test, the pressure of supply water that is provided for fine mist spray head 5 when the entry mouth of pipe 6 is during at 1.0-1.2Mpa, and the effect of thin water smoke atomizing be the best.The fire extinguishing effect also is best.
