Background technology
As everyone knows, in daily life, fire is recurrent.In recent years, along with the modern industry rapid economy development, the various places fire incident takes place frequently, and has brought great spirit and material damage for the local government and the common people.Development is efficient, environmental protection, simple and direct, reliable extinguishing device, and the portable extinguishing device that puts out the small-sized initial fire disaster of common pilosity has become the market in urgent need of fire-fighting equipment with particularly being convenient to maneuverability.
Backpack fire extinguisher with atomization device is just at the market demand, utilizes the plurality of advantages such as efficient, environmental protection, low cost, wide adaptation, high reliability of thin water smoke, and its development is become drive of high-pressure gas, manually bears the backpack extinguishing device of operation.Having given full play to the advance of thin water smoke and the maneuverability of backpack extinguishing device, is the jinx's equipment that puts out common multiple small-sized initial fire disaster.Just because of the plurality of advantages of this device, Backpack fire extinguisher with atomization device becomes the main flow equipment that current public security fire-fighting puts out common multiple small-sized initial fire disaster just day by day.
At present, known Backpack fire extinguisher with atomization device is representative with the two phase flow Backpack fire extinguisher with atomization device of German AFT company, it is power source that this device adopts high pressure air reducing to the pressure below the 1MPa, after foam solution pressurization to premix, in the lump post-decompression low-pressure gas is inserted the two phase flow spray gun, mix forming thin water smoke then by the gas-liquid internal mix chamber in the spray gun continuously, realize the function conversion of thin water smoke and foam by the shower nozzle of conversion two phase flow gun head.The maximum of this device is sorry to be that air respiratorresuscitator commonly used is not set, and makes its practical scope dwindle greatly.As leave no choice but use, operating personnel need to wear the air respiratorresuscitator of a tool necessity again when entering the scene of a fire, to ensure its normal safety work.Certainly will increase the weight of operating personnel's burden like this, have a strong impact on its operating efficiency, the fire-fighting fire extinguishing practicality is not strong.
For this reason, many manufacturers and knowledgeable people develop and study, but do not have ideal method to solve the problem of above-mentioned existence so far as yet.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing Backpack fire extinguisher with atomization device exists, the purpose of the invention just provides the single-phase flow Backpack fire extinguisher with atomization device of a kind of simple and reasonable, safe and reliable, simple and direct practicality, high-efficiency environment friendly.
The invention solves the technical scheme that its technical problem adopts, it comprises backboard, fluid reservoir, spray gun, fluid reservoir is fixedly installed on the backboard, backboard is provided with braces, spray gun is connected with the fluid reservoir bottom by the high pressure tube connector, one side of described fluid reservoir is provided with gas cylinder, on the backboard of fluid reservoir opposite side, be provided with the gun barrel that inserts spray gun, gas cylinder connects the pressure-reducing valve with an intake interface and two interfaces of giving vent to anger, the check valve of leading up to of pressure-reducing valve is connected with fluid reservoir top, and another road of pressure-reducing valve is connected with the positive-pressure type air respiratorresuscitator.
The further preferred version of the invention, described positive-pressure type air respiratorresuscitator comprises respirator pressure-reducing valve, Pressure gauge and the breathing mask with an intake interface and two interfaces of giving vent to anger, and Pressure gauge is connected with two interfaces of giving vent to anger of respirator pressure-reducing valve with breathing mask is corresponding.
The further preferred version of the invention, described fluid reservoir is provided with spring loaded safety valve, and the closed container of fluid reservoir covers and is provided with pressure-relief valve.
The further preferred version of the invention, described fluid reservoir is provided with the diaphragm type safety valve.
The further preferred version of the invention, the high pressure tube connector that is connected with spray gun is provided with snap joint.
The further preferred version of the invention, described spray gun can produce foam or thin water smoke by mode conversion switch.
After adopting said structure, the invention utilizes the source of the gas of the interior gases at high pressure of gas cylinder as the positive-pressure type air respiratorresuscitator, to the operating pressure of the foam mixing liquid application system in the fluid reservoir, the foam mixing liquid in the fluid reservoir is gone out thin water smoke by the special-purpose lance ejection that can produce foam put out a fire simultaneously.Under driving, the middle low pressure about 1.5MPa makes the water microatomization by special-purpose spray gun, according to U.S. NFPA750 standard, on the plane at 1 meter of nozzle, can record water smoke the thin water smoke diameter of the water mean particle dia Dvf0.99 of thick part can reach the 85-120 micron, range can be above 7 meters.Can realize the dual-use function of efficient thin water mist spray of single-phase flow or foam fire-fighting by the mode conversion switch of special-purpose spray gun.This device can effectively put out A, B, E class fire, and is particularly evident to the initial stage and the small-sized fire effect thereof of A, B, E class fire especially.Contrast conventional apparatus structure is science, reasonable more, uses simpler and more direct, efficient.
