Abstract
The invention provides a new froth fire extinguishing system, which solves the technical problem that the foam concentrate used in the exiting froth fire extinguishing system is non-alcohol type foam concentrate, and the foam concentrate fails to put out the fire caused by water-soluble flammable liquid. The invention comprises a case and a foam concentrate tank (1) arranged in the case, a foam concentrate sucker (2), a foam concentrate control valve (3), a check valve (4), a foam concentrate proportioner (5), a flow pipe (8), a flow pipe control valve (6) and a coupling hose (9); the foam concentrate in the foam concentrate tank (1) is gel-type alcohol-type fire foam. The new froth fire extinguishing system has the advantages of effectively putting out the fire caused by both alcohol-type flammable liquid and non-alcohol type flammable liquid.
Description
Technical field
The present invention relates to a kind of fire-fighting equipment, particularly a kind of froth fire extinguishing system.
Background technology
Froth fire extinguishing system has integrated system and distributed system, integrated system is convenient to management, but for the highway long tunnel because fire fighting supply pipeline and foam pipeline are long, when breaking out of fire, existence is long to the required time of ejection foam fire-fighting from starting fire extinguishing system, can cause effective attack time to incur loss through delay, thereby and understand the wasting problem of residual a large amount of foam mixing liquid in the back pipeline of fire extinguishing; Distributed system is at each fire hydrant place in tunnel foam extinguishing box to be set, and foam fire-fighting water supply network and fire hydrant water supply pipe net system share, and during fire extinguishing, foam solution does not enter the fire hydrant water supply pipe net system.Open water supply control valve, utilize the hydraulic pressure water outlet of fire hydrant water system,, suck foam solution and spray foam fire-fighting through foam gun through foam proportioner.But vcehicular tunnel might pass through the vehicle of the various hazardous chemicals of transportation, and the foam solution that uses in the existing froth fire extinguishing system is non-anti-capacitive foam solution, and this foam solution can not put out water-soluble inflammable, flammable liquid fire.Simultaneously, it is 0 ℃ one 40 ℃ that the storing temperature of foam solution requires, and it is 4 ℃ one 35 ℃ that the water temperature that is used to prepare the foam mixing liquid of fire extinguishing requires, and the temperature in some northern area tunnels is at subzero tens degree in the winter time, make the existing foam extinguishing box can't operate as normal, have influence on the fire extinguishing effect.Simultaneously under low temperature environment, foam extinguishing box is after closing water system after the fire extinguishing, remain in the mixed liquor of foam in water supply line and the proportioner and water and can Yin Wendu descend and freeze, thereby bursting by freezing proportioner and associated conduit and parts make the fire extinguishing system can't operate as normal.
Summary of the invention
The invention solves the foam solution that uses in the existing froth fire extinguishing system and be non-anti-capacitive foam solution, and this foam solution can not put out the technical problem of water-soluble inflammable, flammable liquid fire, and a kind of novel foam extinguishing system is provided.
The present invention overcomes the above problems by following scheme:
Novel foam extinguishing system, comprise concentrated tank 1, foam solution suction pipe 2, foam solution control valve 3, check-valves 4, foam solution proportioner 5, feed pipe 8, the feed pipe control valve 6 that is provided with in casing 16 and the casing 16 and be connected flexible pipe 9 that the foam solution in the described concentrated tank 1 is the anti-fire foam that holds of gel-type.
The tank body of described concentrated tank 1 is provided with heating cable 14, and the tank body of concentrated tank 1 is outside equipped with heat-insulation layer 15, and feed pipe 8 is provided with residual liquid escapo valve 17, the bayonet joint that is connected to of proportioner 5 and reel central tube 13.
The heating cable 14 that is provided with on the tank body of described concentrated tank 1 is permanent power ribbon heater.
The thickness of described heat-insulation layer 15 is 20mm, and the material of heat-insulation layer 15 is rubber and plastic sponges.
The invention has the beneficial effects as follows can put out effectively that aqueous fusion is inflammable, fire that flammable liquid and water-insoluble inflammable, flammable liquid etc. cause.For cold district provides a kind of high-effect fire-extinguishing device that not influenced by temperature, be specially adapted to the distributed foam extinguishing box in the tunnel.

The specific embodiment
The present invention will be described below in conjunction with accompanying drawing:
Novel foam extinguishing system, comprise the concentrated tank 1 that is provided with in casing 16 and the casing 16, foam solution suction pipe 2, foam solution control valve 3, check-valves 4, foam solution proportioner 5, feed pipe 8, feed pipe control valve 6 be connected flexible pipe 9, foam solution proportioner 5 is by the be connected to bayonet joint of flexible pipe 9 with reel central tube 13, reel central tube 13 links together with flexible pipe 7, flexible pipe 7 dishes are on pipe crimping dish 12, the end of flexible pipe 7 is connected with foam and robs control valve 10 and foam generation rifle 11, and the foam solution in the described concentrated tank 1 is the anti-fire foam that holds of gel-type.
The tank body of described concentrated tank 1 is provided with heating cable 14, and the tank body of concentrated tank 1 is outside equipped with heat-insulation layer 15, and feed pipe 8 is provided with residual liquid escapo valve 17, the bayonet joint that is connected to of proportioner 5 and reel central tube 13.
The heating cable 14 that is provided with on the tank body of described concentrated tank 1 is permanent power ribbon heater.
The thickness of described heat-insulation layer 15 is 20mm, and the material of heat-insulation layer 15 is rubber and plastic sponges.
