The urban turbojet fire vehicle plays an important role in extinguishing high-rise building fire disasters, unattended dangerous chemical warehouse fire disasters, underground garage fire disasters, cable trench fire disasters, tunnel fire disasters, historic building fire disasters and steamship cabin fire disasters.
Description
Technical field
The invention belongs to fire-fighting domain, is a kind ofly to take turbojet engine as spraying power, the compound fire fighting truck of multiple extinguishing chemical capable of simultaneous injection specifically.
Background technology
Fire fighting truck is current for putting out the high maneuverability of all kinds of fire fire-fighting equipment of advocating war.In fire fighting, expose following shortcoming: the one, can only spray single extinguishing chemical, can not bring into play the fire extinguishing strong point of heterogeneity extinguishing chemical, two or more extinguishing chemicals are combined in to composite injection, for putting out fast combustible material fire simultaneously; The 2nd, the extinguishing chemical ejecting lacks dispersivity, for maintaining extinguishing chemical, in fire three dimensions, has a rate, the spray fire extinguishing agent continuously of having to, so that cause serious water damage and the chemical contamination to environment; The 3rd, while putting out the fire in confined space, must open up fire extinguishing passage, so that find burning things which may cause a fire disaster, put out, cause thus fresh air to enter indoor, increase fire extinguishing difficulty, increase attack time.As everyone knows, water jet has the ability of fabulous impacting flame and radiating and cooling, but it stops the ability of oily fiery resume combustion to can not show a candle to fire foam; Fire foam has the ability of the fabulous fiery resume combustion of prevention oil, but its blow-off velocity can not show a candle to ultra-fine dry powder extinguishing agent; Ultra-fine dry powder extinguishing agent has high fire extinguishing effectiveness, but a little less than penetrating flame ability and stop oily fiery resume combustion ability all when putting out outdoor big fire.Therefore, the extinguishing chemical of different qualities is combined and ejected from same injection apparatus, bring into play the chief separately of different extinguishing chemicals, formation has the compound fire-extinguishing agent of Combined extinguishing advantage, can significantly shorten attack time, realize and control fast the intensity of a fire and put out all kinds of fire, reduce the pollution to environment, to the future development of realizing fire fighting " making short work of ".
Summary of the invention
In order to address the above problem, the invention provides that a kind of various extinguishing chemical can be controlled separately and the large flow of good airproof performance, large area, and the strong turbojet fire engine of dispersivity.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of city turbojet fire engine, comprise automobile chassis, on automobile chassis, be provided with ultra-fine dry powder tank, ultra-fine dry powder tank is connected with nitrogen cylinder pressure vessel, nitrogen cylinder pressure vessel is connected with water pump system, and water pump system is connected with a flow container assembly, and flow container assembly connects turbojet engine jet assembly, turbojet engine jet assembly includes injection apparatus, and injection apparatus connects center steering body by tube connector.
Center steering body of the present invention comprises center steering body case, center steering body inner casing and multilayer inner sleeve, wherein ground floor inner sleeve is hydraulic oil oil duct and diesel oil oil duct, second layer inner sleeve is aquaporin, aquaporin is ring-type, the 3rd layer of inner sleeve is powder extinguishing agent passage, bottom at center steering body is also provided with multi-line electric slip ring, and diesel oil oil duct, aquaporin, powder extinguishing agent passage and hydraulic oil oil duct be isolated sealing mutually.
Injection apparatus of the present invention includes playpipe, is disposed with from right to left water and foam collecting ring, thin water smoke collecting ring on playpipe, in the inside of playpipe, is provided with ultra-fine dry powder jet pipe.
Injection apparatus of the present invention, by special structural design, various extinguishing chemicals can be inputted respectively and ejection simultaneously, various extinguishing chemicals can be distinguished control separately, non-interference, at desired location, mix in proportion, various dissimilar and extinguishing chemicals performance are organically combined, play performance compatibility, the effect of mutual supplement with each other's advantages.
Center steering body whirligig of the present invention, is divided into shell and multilayer inner sleeve, and outermost layer is housing parts, and inner ground floor inner sleeve is divided into several runners, respectively by multipath hydraulic oil and diesel oil; Second layer inner sleeve is water route, is a ring-type; The 3rd layer of inner sleeve is dry powder pipeline; Bottom is electric slip ring structure; It is independent each other that this slewing equipment can be realized medium, the effect of rotatory sealing simultaneously.
Fire fighting truck of the present invention is cut into thin water smoke by turbojet engine tail gas by water, use compressed gas-driven ultra-fine dry powder extinguishing agent, ultra-fine dry powder extinguishing agent passes through converging portion, flow is constant, flow velocity is accelerated, enter afterwards atomising device diffuser, be present in the ultra-fine dry powder rapid expanding in the nebulization channel of diffuser in Compressed Gas, fluid volume is expanded, under the parcel of thin water smoke and turbojet engine tail gas, accelerated fully, spouting from injection channel with very high speed and very little angle of flare, form large flow, large area, the cold aerosol fire extinguishing agent that dispersivity is strong.
The present invention compared with prior art, its remarkable advantage has: (1) has huge injection capacity, can eject at short notice large flow " tail gas-water smoke-ultra-fine dry powder " three-phase jet extinguishing chemical, have and fabulous from three dimensions, control the intensity of a fire, put out big fire and be the aeration-cooling ability in the scene of a fire.Conventional fire fighting truck makes to put out a big fire, and will to transfer tens of to up to a hundred fire fighting trucks belligerent because injection capacity is not enough, has the turbojet fire engine of huge injection capacity can alleviate this difficult problem, is a kind ofly for putting out " trump card " of oil gas big fire, to equip.(2) proportion of the cold aerosol fire extinguishing agent ejecting and air approach, can replace supplemental air flow to enter the combustion zone in tunnel, also can enter with the flue gas rising the overhead of ancient building, put out fast the big fire in the enclosure space that other extinguishing chemical is difficult to inject and put out, in putting out high-rise building fire, unattended Hazardous Chemical Substances Warehouse Fire, underground garage fire, cable duct fire, tunnel fire hazard, ancient building fire, steamer cabin fire, play a significant role.
