The specific embodiment
See also shown in Figure 1ly, it is the schematic diagram of long channel water fire extinguishing system one preferred embodiment of the present invention.Long channel water fire extinguishing system 100 is to be applied in the long-channel 110, as the Shopping Arcade, or as the gallery in office block, hospital, hotel etc.Long-channel 110 has an air intake vent 112 and an air outlet 114.Long channel water fire extinguishing system 100 comprises the one first water smoke proscenia 120 that is disposed at air intake vent 112 tops, be disposed at the one second water smoke proscenia 130 at air outlet 114 tops, and at least one the 3rd water smoke proscenia 140 that is disposed at the top between air intake vent 112 and the air outlet 114.
As fire-fighting is unexpected when taking place, start this long channel water fire extinguishing system 100, be arranged at the vertical water veil that vertical shower nozzle 142 of the 3rd water smoke proscenia 140 in the long-channel 110 is sprayed by fixed point, long-channel 110 can be divided into a plurality of fire-fightings interval 150.The vertical water veil that is produced by vertical shower nozzle 142 of the 3rd water smoke curtain 140, the effect of washing cigarette can be provided, obstruct by the vertical water veil, can reduce the diffusion rate of dense smoke effectively, avoid the harmful smog in the single fire-fighting interval 150 at disaster scene, diffuse in other the fire-fighting interval 150.Thus, can prolong escape time, reduce disaster Field Force's injures and deaths.Vertically the jet angle of shower nozzle 142 is between 55 degree are spent to 85.
Because in the disaster scene; the air of burning things which may cause a fire disaster 160 tops can rise because of expanded by heating; can comprise horizontal shower nozzle 146 in the 3rd water smoke proscenia 140; because the high hot dense smoke that produces during fire can accumulate in the top of long-channel 110; therefore; adsorbable by the horizontal water smoke that horizontal shower nozzle 146 is sprayed in dense smoke, to reduce the temperature of dense smoke, can delay or reduce flash burn (flash over) crisis.In addition, because dense smoke is wetting by the aqueous vapor of horizontal water smoke institute, therefore, the weight of dense smoke also increases thereupon, has reduced the diffusion rate of dense smoke widely, can prevent effectively that the intensity of a fire from enlarging.Laterally the jet angle of shower nozzle 146 is spent between 35 degree about 5.
Owing to dense smoke can be because of the thermal expansion accumulation that makes progress, thereby make between burning things which may cause a fire disaster 160 and surrounding air and produce negative pressure, cause near the air the burning things which may cause a fire disaster 160 can flow to burning things which may cause a fire disaster 160 to replenish.Based on this kind phenomenon, the small water smoke that vertical shower nozzle 142 of the 3rd water smoke proscenia 140 or horizontal shower nozzle 146 are sprayed can flow to burning things which may cause a fire disaster 160 along with the traction of air-flow.The wettable dense smoke of this small water smoke improves the humidity in the fire-fighting interval 150 at disaster scene, and the particle in the absorption dense smoke and unburned intermediate product completely.And, therefore, can reduce the temperature arround the burning things which may cause a fire disaster 160 effectively because water smoke can be taken away a large amount of heats when being evaporated to steam.Thus, can reduce airborne oxygen concentration, improve the reaction condition of burning, prevent flash burn, and reduce the scope of burn rate, restriction burning, prolong the possibility of burning with reduction.
Be disposed at the water smoke curtain that the first water smoke proscenia 120 of air intake vent 112 is sprayed, the air current flow direction that can cooperate existing exhaust equipment, the wetting air that flows in the long-channel 110, increase the content of water in air gas, be rich in aqueous vapor air can along with the drag flow of air to the zone of burning things which may cause a fire disaster 160, can reach the effect that reduces flame temperature, reduces the control intensity of a fire such as flash burn equally.Learn that according to experiment the water smoke diameter of water smoke curtain is preferably between 100-1000 μ m can reach the desired effect that moves along with air-flow.Diameter as water smoke is too small, and then cooling effect is not good, and is excessive as the diameter of water smoke, then can't be along with the air drift.
Be disposed at the water smoke curtain that the second water smoke proscenia 130 of air outlet 114 is sprayed; the defence line of washing cigarette together can be provided; in time wash and wetting dense smoke; to reduce its temperature and diffusion rate; make dense smoke be difficult for blowing out outside the long-channel 110; the influence of avoiding smoke exhaust pipe Yin Gaore dense smoke reduces avalanche because of structural strength, protects the smoke exhaust pipe of exhaust equipment effectively, and prevents that dense smoke from scurrying burning.
Long channel water fire extinguishing system 100 comprises a water system, is disposed in the long-channel 110, and so that the first water smoke proscenia 120, the second water smoke proscenia 130 to be provided, the water source required with the 3rd water smoke proscenia 140.Also comprise a plurality of control modules in the long channel water fire extinguishing system 100, with the first water smoke proscenia 120, the second water smoke proscenia 130, and the 3rd water smoke proscenia 140 links to each other.Control module comprises a sensing element and a driving element at least, with when sensing the generation of fire-fighting disaster, can drive the first water smoke proscenia 120, the second water smoke proscenia 130 and the 3rd water smoke proscenia 140.Long-channel fire plant 100 can more comprise an exhaust equipment, is disposed at air outlet 114 places of long-channel 110.
Water smoke proscenia 120,130 and 140 formed water smoke curtains in the long channel water fire extinguishing system 100, its main purpose is non-in order to direct strike or encirclement burning things which may cause a fire disaster 160, but in order to wash cigarette, cooling, and the content of aqueous vapor in the increase atmosphere, with with the disaster field control in single fire-fighting interval 150, reduce the dense smoke diffusion rate and prolong the possibility of burning.Yet, the 3rd water smoke proscenia 140 of long channel water fire extinguishing system 100 also can more include oblique shower nozzle 148, horizontal water smoke than vertical water veil of washing cigarette and cooling, the water smoke that oblique shower nozzle 148 is sprayed can more directly contact with burning things which may cause a fire disaster, to increase water smoke density, can assist fire extinguishing further.
See also shown in Figure 2ly, it is the schematic diagram of another preferred embodiment of long channel water fire extinguishing system of the present invention.The long-channel of present embodiment is to be an iron vcehicular tunnel 200.And in iron vcehicular tunnel 200, the burning things which may cause a fire disaster of fire (as fuel tank or pipeline leak, gasoline drippage etc.), multidigit belongs to covering property fire (hidden fire), therefore in automobile chassis or below, compartment, be difficult to directly hit the mode of burning things which may cause a fire disaster, reach the purpose of fire extinguishing.
In the present embodiment, the first water smoke proscenia 220, the second water smoke proscenia 230 of long channel water fire extinguishing system deironing vcehicular tunnel top, outside the 3rd water smoke proscenia 240, comprise that more fixed point is disposed at a plurality of sprayer units 250 on iron vcehicular tunnel 200 sidewalls.The distance h on sprayer unit 250 and ground, being preferably is between 20 centimeters to 50 centimeters, the smoke sensing sprayer unit that this distance h is more general is more pressed close to burning things which may cause a fire disaster, therefore, can increase water smoke density above the ground, and more direct effective fire-fighting efficiency is provided.
