Description
Technical field
The present invention relates to a kind of mobile fire extinguisher with fine spray nozzle of the preamble corresponding to claim 1.
Background technology
The present invention can be applicable to and puts out red-hot liquid substance.It is particularly suitable for being applied in the place that liquid extinguisher causes bigger damage.In fire-fighting technique, consider the mobility of extinguishing device, the branch of mobile fire extinguisher and static fire extinguisher is arranged.Static fire extinguisher is such fire extinguisher, and it can be fixedly mounted in the building.It has foamite container and leads to the pipeline of the assembly of putting out a fire.Be usually directed to fighting nozzle at this, the wherein known jet angle that has until 60 °.This jet angle is regulated like this, and the feasible big as far as possible area that is positioned at the zone of nozzle below is crossed spray (overspray), so that spatially keep fewer purpose nozzle and only spray the extinguishing chemical that needs quantity.In order to spray the least possible extinguishing chemical, fire extinguisher with fine spray nozzle is common.
Wheeled apparatus generally includes a portability and movably foamite container and a fighting nozzle, and the pipeline of a flexible pipe shape is set on described foamite container.The purpose of wheeled apparatus is to put out a fire as far as possible apace, wherein is distributed on the zone of origin at short notice by means of a large amount of liquid-state extinguishing agent of pressed gas.The advantage of mobile fire extinguisher is, can target control the distribution of extinguishing chemical on zone of origin exactly.The extinguishing chemical volume of mobile fire extinguisher can reach 50 liters.
Be distributed on the zone of origin owing in the shortest time, will have the extinguishing chemical of big drop diameter, thereby can cause big extinguishing chemical to destroy.After utilizing the mobile fire extinguisher fire extinguishing, produce such problem, mobile fire extinguisher promptly not only all forms very big injury, and had such needs since considerable time, even also will be configured to cause as far as possible little water destruct to the user but also to insurance.Utilize mobile fire extinguisher of today still can not address this problem.
Come method for extinguishing fire and device by known a kind of the extinguishing device of DD299098 based on water and propellant by means of automatic movable type or state type, wherein water is stored in the water receptacle and propellant is stored in it in the pressure vessel discretely, and two kinds of liquid arrive after Open valve is opened fast in the spraying chamber according to the work of vaporization principle, put out a fire by heat absorption after forming aerosol and leaving the chamber of spraying in this spraying chamber.Propellant is with in water receptacle is arranged on different spaces, and the chamber of wherein spraying is connected with a hard-wired pipe-line system.For this device, do not relate to a kind of fire extinguisher, and relate to a kind of extinguishing device, it is according to the work of vaporization principle.The acting device that in this device, does not have direct aligning zone of origin.
Described a kind of mobile fire extinguisher in GB2320189A, it has a spray gun with jet blower, can produce spraying by means of this nozzle, and wherein nozzle is with one 130 ° angle eject drops.This spraying is not suitable for aiming at the injection on burning things which may cause a fire disaster ground.
By the known a kind of spray nozzle device that produces the mist field on plane of WO 2004/105957A1, utilize it spraying can be aimed at zone of origin, but this is a kind of hard-wired extinguishing device with pipeline.
Be not known that a kind of like this mobile fire extinguishing device as yet, its acting device target under less water consumption and higher fire extinguishing effect is used at zone of origin exactly.
Summary of the invention
The objective of the invention is to, develop a kind of mobile fire extinguisher with fine spray nozzle, can put out a fire as far as possible apace and the caused damage minimum of extinguishing fluid by this fire extinguisher.
This purpose realizes by the mobile fire extinguisher with fine spray nozzle according to claim 1 feature.
Dependent claims has provided favourable structure of the present invention.
The present invention is provided with the preferred portable fire extinguisher with fine spray nozzle of a kind of movable type, it comprises foamite container, valve, extinguishing chemical pipeline and the extinguishing chemical nozzle that contains watery extinguishing chemical, and wherein the extinguishing chemical nozzle is that the memory of a fine spray nozzle and pressed gas is arranged on the foamite container or in it.
The fine spray nozzle advantageously has a jet angle that is 30 ° to the maximum.It is hereby ensured that the fine spray that is produced is carried towards zone of origin with a narrower angle.The fine spray The Application of Technology is particularly suitable for mobile field.With different in the static applications of fine spray extinguishing device, wherein the water effect mainly is that plane earth acts on zone of origin from the top or from the below, and beam directly can be aimed at the conversion zone of fire when mobile extinguishing device expertly.Particularly when the fire of the quick upgrading of opening wide, utilize relatively little fire extinguishing water consumption to realize high efficiency fire extinguishing at first thus.The water of atomized spray has the heat absorption capacity of raising with its contact surface that significantly amplifies subtly, because violent vaporization interrelates by replacement of oxygen and temporary transient inertia effect.Can obtain short especially attack time thus.Between valve and fine spray nozzle, be advantageously provided the flexible pipe of a flexibility.Advantageously use and have the watery solution of foaming agent as extinguishing chemical.In addition advantageously, use CO
2, N
2, Ar or compressed air is as propulsive gas.Propellant can be kept at one and be arranged in inside or outside propulsive gas storage container.
Design injection nozzle like this makes the drop size of maximum of extinguishing chemical be 0.1mm.In addition advantageously, a filter screen is set in foamite container.Can propulsive gas be joined in the extinguishing fluid with different operating pressures.Operating pressure can consider 16 to 50bar down to 16bar in middle pressure device in low-voltage device, and wherein high-pressure installation can consider to be higher than 50bar.Advantageously, the initial pressure that has 30bar.
Description of drawings
By means of three accompanying drawings and an embodiment the present invention is set forth below.Wherein:
Fig. 1 has a fire extinguisher with fine spray nozzle that is arranged on the pressure vessel in the foamite container;
Fig. 2 has the schematic diagram of the fire extinguisher with fine spray nozzle of the pressure vessel that externally is provided with;
Fig. 3 does not have the fire extinguisher with fine spray nozzle of independent pressure vessel.
The specific embodiment
Fig. 1 shows a fire extinguisher with fine spray nozzle, comprises that one contains the pressure vessel 1 of watery extinguishing chemical, and the fire extinguisher pipeline with filter screen stretches in the described pressure vessel 1, wherein is provided with one in foamite container 1 and contains CO
2 Pressure gas container 2, thereby the pressure on the valve 5 exists along pipeline 9.Fighting nozzle 7 is an injection nozzle, and its jet angle 8 is 30 °.
Fig. 2 shows a fire extinguisher 1, a pressure gas container 2 externally is set on this fire extinguisher and the pipelines 6 of a flexibility are set in the middle of valve 5 and fine spray nozzle 7.The jet angle 8 that is similarly 30 ° is used for spraying is assigned to burning things which may cause a fire disaster ground apace and neatly.The pressure of extinguishing fluid is 16bar.Except quick extinguishing, fire extinguisher has such advantage, and promptly the point less water yield of dripping form is assigned to burning things which may cause a fire disaster ground, thereby it is bad to produce little damage by water.
Fig. 3 illustrates a fire extinguisher 1, and the pressed gas 2 that does not wherein have independent container is arranged on the top of extinguishing chemical 3 and extinguishing chemical is extruded fire extinguisher 1.
