Background technology
In air, froth fire extinguishing system, the abundant Degree of Accord Relation of gas-liquid mixed is to the coefficient of foaming of fire foam, coefficient of foaming is the important indicator of system fire extinguishing effectiveness, and the jet length of mixed liquor after foaming is the important performance indexes of system fire suppression applications ability.
Existing fire extinguishing system comprises fixed or portable fire extinguishing system, no matter fixed or portable fire extinguishing system is mainly spray power with liquor pump, its fire foam jet length formed is limited, and covering power is poor, is not suitable with the fire extinguishing needs in present multimode, the larger scene of a fire.
Summary of the invention
The utility model discloses a kind of wind-force froth fire extinguishing system according to the deficiencies in the prior art.Problem to be solved in the utility model is to provide one and water, fire foam, air three can be mixed by corresponding proportion, sprays high-expansion air foam extinguishing chemical, take wind-force as the multifunctional fire extinguishing system of major impetus.
The utility model is achieved through the following technical solutions:
Wind-force froth fire extinguishing system, is made up of spraying system, water system, air supply system and foam supply system, it is characterized in that:
Described spraying system is communicated with foam supply system with water system, air supply system, and wherein water system, air supply system are self-powered supply systems, foam supply system provides power by venturi negative voltage supply device provisioning foam mixing liquid by water system;
Spraying system is cylindrical hollow configuration, is independently arranged on backpack or dolly removable frame body, comprises: the fire extinguishing jet pipe of front end, the water at middle part, foam, air mixing device, each medium inlet of rear end.
Described spraying system comprises: the air foam mixed liquor fire extinguishing jet pipe being arranged at front end; Put out a fire jet pipe at same axis, the air intake arranging rear end with mixed liquor; Be arranged at extinguishing chemical entry to mixed solution and the extinguishing chemical mixture export of air intake axis centre; Be arranged at mixed liquor fire extinguishing jet pipe and air intake joint portion, uniform intervals and spray angle around the water arranged, water injection angle axis and mixed liquor sprayer for extinguishing fire pipe axis angle are 17 ~ 30 degree; Water sprays angle and mixed liquor jet pipe of putting out a fire and is communicated with the ring-shaped liquid chamber of air intake joint portion outer wall, the water inlet that ring-shaped liquid chamber has water system to be communicated with; Extinguishing chemical entry to mixed solution and venturi-type eductors outlet, venturi-type eductors suction inlet passing ratio control valve is communicated with foam supply system, arranges bypass waterway be communicated with venturi negative pressure injector at the water inlet in ring-shaped liquid chamber.
Described air supply system is arranged on backpack or dolly removable frame body, comprises two stroke gasoline engine and hair-dryer.
Described foam supply system is arranged on backpack or dolly removable frame body, comprise the fire foam container of sequential communication, check valve, ratio adjusting valve, venturi-type eductors suction inlet, venturi-type eductors entrance and water inlet arrange bypass waterway and are communicated with, and venturi-type eductors outlet is communicated with extinguishing chemical entry to mixed solution.
Described water system comprises fire fighting truck, post fire hydrant or/and hand lifts water supplying pump device.
Above-mentioned water sprays miter cut ring around layout 6.
Described extinguishing chemical entry to mixed solution and bypass waterway be arranged in parallel, and bypass waterway is positioned at extinguishing chemical entry to mixed solution and fire gun tube wall connecting portion.
The utility model can be set to a kind of portable wind-power spray froth fire extinguishing system.Comprise as backrest being born fire foam container, bypass venturi-type eductors, proportion adjustment valve, and connect the spraying system of hand-held control formula, by outer watering, as water tanker, post fire hydrant, hand lift water supplying pump, use rated pressure at 0.8mpa compressed air.Outer injection for wind-force water spray and wind-force air foam can be realized switch, be applicable to all kinds of fire.Comparing this equipment with pure water fire extinguishing can make blow-off velocity improve 3-5 doubly, reduces fireman's time at the scene and the loss of on-the-spot fire; Reduce the surface tension of water, add penetration, improve fire-fighting efficiency greatly.
Outer watering various ways, 0.4mpa-1.2mpa all can use, and namely fire hydrant, hand are lifted the pressure of supply water such as pump, fire fighting truck and can be run well.When outer watering supply, water inlet bypass waterway flows to venturi-type eductors, form the extinguishing chemical that negative pressure passing ratio control valve draws certainty ratio, be exported to extinguishing chemical entry to mixed solution, extinguishing chemical mixture export by venturi-type eductors again extinguishing chemical sprayed to spray to cross clash into outer watering inclined hole, form great negative pressure, spraying system end sucks a large amount of hair-dryer malleation blast air again, make water, fire foam, air three mixes by corresponding proportion, eject 7-20 air foam doubly.
The utility model system passing ratio control valve regulates foam humidity according to scene of a fire present situation, and system uses structure more succinct, easy to operate, reduces system equipment cost.
The utility model take wind-force as the injection power of fire extinguishing system, and devise spraying system according to wind-force feature of spraying, the utility model is not when opening liquid and fire foam path, can be used as air extinguishing device and be applied to the environment such as forest extinguishing, after unlatching liquid and/or fire foam path, can be applicable to multiple fire extinguishing environment; Spraying system structure is more excellent, what spraying system achieved extinguishing chemical and water is thoroughly mixed to form foam, foam and spray further under the driving of power wind, jet length extends greatly, more be conducive to the application of the large scene of a fire, under scene of a fire traffic relative difficulty condition, the system that can give full play to is light, conveniently moving, closely realize the object of large power fire extinguishing.The each system fading margin of the utility model is convenient, and application efficiency and function are greatly improved.
