Description

소방차용 압축공기 포 소화설비Compressed air fire extinguishing equipment for fire trucks
본 발명은 소방차용 압축공기 포 소화설비에 관한 것이다.The present invention relates to a compressed air fire extinguishing system for a fire engine.
일반적으로 화재를 막거나 억제시키기 위하여 소화설비가 사용된다. 이러한 소화설비는 화재의 초기단계에서 소화약제가 갖는 냉각 또는 공기차단 등의 효과를 이용해 소화를 한다.In general, fire extinguishing equipment is used to prevent or suppress fires. In the initial stage of a fire, these fire extinguishing facilities use the effect of cooling or air blocking of the extinguishing agent to extinguish the fire.
이때, 소화설비에는 포 소화설비, 분말소화설비, 할론소화설비, 이산화탄소소화설비 등의 종류로 되어있으며 각 상황에 맞게 사용된다.At this time, the fire extinguishing equipment consists of foam fire extinguishing equipment, powder fire extinguishing equipment, halon fire extinguishing equipment, carbon dioxide extinguishing equipment, etc., and is used according to each situation.
여기서 포 소화설비는, 물과 포소화약제가 일정한 비율로 혼합된 포(foam)가 공기에 의하여 발포되어 형성된 미세한 기포의 집합체가, 연소물의 표면을 덮어 공기를 차단함으로써 질식 및 냉각소화를 하게 된다.Here, in the foam fire extinguishing system, the aggregate of fine bubbles formed by foaming with air, in which water and foam extinguishing agent are mixed in a certain ratio, cover the surface of the combustible material to block the air, thereby suffocating and cooling fire extinguishing. .
또한, 포에 함유된 수분의 의한 냉각효과와 질식효과를 사용하여 소화가 필요한 곳은 압축공기 포 소화장치를 작동시켜서 압축공기 포(Compressed Air Foam)로 소화시킨다.In addition, using the cooling effect and suffocation effect of the moisture contained in the foam, the compressed air foam extinguishing device is operated to extinguish the fire with compressed air foam.
근래에 들어 소방 펌프차에 유류 및 특수가연물 화재 소화를 위해 압축공기포 소화장치를 설치하고 있다. 여기서 압축공기 포 소화장치를 소방 펌프차에 설치하는 경우, 소방호스 연결구와, 압축공기 포 연결구를 각각 설치함에 따라 복잡한 구성으로 인해 사용성이 낮아지고, 공간적 활용이 어려운 문제가 있다.In recent years, compressed air bubble extinguishing devices have been installed in fire pump vehicles to extinguish oil and special combustible fires. Here, when the compressed air fire extinguishing device is installed in a fire pump vehicle, as the fire hose connection part and the compressed air bubble connection part are installed respectively, the usability decreases due to the complicated configuration, and space utilization is difficult.
그리고 압축공기 포 소화장치는 소화수, 포 소화약제 및 압축공기를 최적의 비율로 혼합시켜 생성된 초 미세거품 형태의 압축공기포(Compressed Air Foam)를 화점에 방사한다.And the compressed air fire extinguishing device emits compressed air foam in the form of ultra-fine bubbles produced by mixing fire extinguishing water, fire extinguishing agent and compressed air in an optimal ratio to the fire point.
여기서 압축공기 포 소화장치에서 소화수는 소화수 펌프에서 공급을 받고, 압축공기는 공기 압축기에서 공급을 받으며, 포 소화약제는 포 소화약제 펌프에서 공급을 받는다.Here, in the compressed air fire extinguishing system, the fire extinguishing water is supplied from the fire extinguishing water pump, the compressed air is supplied from the air compressor, and the foam fire extinguishing agent is supplied from the fire extinguishing agent pump.
종래에는 소화수 펌프와, 공기 압축기는 소방차 엔진과 연결되는 동력 인출 장치로부터 구동력을 제공받고, 포 소화약제 펌프는 소방차에서 공급되는 전원으로부터 구동력을 제공 받는다.Conventionally, a fire extinguishing water pump and an air compressor receive driving force from a power take-off device connected to a fire engine engine, and a fire extinguishing agent pump receives driving force from a power supply from a fire engine.
이에 따라 종래에는 압축 공기 포 소화장치를 사용하는 경우, 소방차 전원 및 엔진에 연결된 동력인출장치를 사용하여 소화수 펌프, 공기 압축기 및 포 소화약제 혼합장치(FOAM PROPORTIONER)의 포 소화약제 펌프를 모두 구동시킨다.Accordingly, in the case of using a compressed air fire extinguishing system in the prior art, the fire engine power source and the power take-off connected to the engine are used to drive the fire extinguishing water pump, the air compressor, and the foam fire extinguishing agent pump of the foam fire extinguishing agent mixing device (FOAM PROPORTIONER). make it
종래에는 포 혼합비 및 소화수 유량의 변화에 따라 포 소화약제 펌프를 변속 운전시켜 해당되는 양의 포 소화약제를 토출시키고 이를 소화수와 혼합하여 정확한 포 혼합비의 포수용액을 만든다.Conventionally, according to the change of the foam mixing ratio and the flow rate of the fire extinguishing water, the foam extinguishing agent pump is operated in a variable speed operation to discharge the corresponding amount of the foam extinguishing agent, and it is mixed with the fire extinguishing water to make a catcher solution of the correct foam mixing ratio.
여기서 종래의 포 소화약제 혼합장치는 변속모터에 플런저 펌프 또는 기어펌프를 설치하여 변속 모터(Variable Speed Motor)의 회전수를 조정하여 필요한 양의 포 소화약제를 토출하는 방식을 갖는다.Here, the conventional foam extinguishing agent mixing device has a method of discharging the required amount of the foam extinguishing agent by installing a plunger pump or a gear pump in the variable speed motor to adjust the rotation speed of the variable speed motor.
그러나 소화수 유량이 클 때 또는 3% 또는 6% 포 혼합비에 필요한 포소화약제 유량이 클 경우, 이에 요구되는 변속 모터의 용량 역시 일정 이상으로 큰 변속 모터를 사용하여야 하나, 소방차에서 공급할 수 있는 전기 용량에 한계가 있기 때문에 현실적으로 적용이 어려운 문제가 있다.However, when the flow rate of fire extinguishing water is large, or when the amount of fire extinguishing agent required for the 3% or 6% foam mixing ratio is large, a variable speed motor with a capacity exceeding a certain size must also be used. There is a problem in that it is difficult to apply in reality because there is a limit in capacity.
또한 포 혼합비를 가변적으로 설정하는 경우, 종래에는 소화수 펌프, 공기 압축기의 구동 회전수의 회전수와, 자동차 엔진의 회전수를 개별적으로 조절해야 하는 구조적 문제가 있다.In addition, when the foam mixing ratio is set variably, there is a structural problem in that the number of rotations of the driving speed of the fire extinguishing water pump and the air compressor and the rotation speed of the automobile engine must be individually adjusted.
또한 포 혼합비를 조절함에 있어서, 종래에는 소화수 유량을 조절하여 공기 포비가 가변되기 때문에, 화재종류에 따라 공기포비를 조절함에 있어서 작동 상의 불편함이 있다.In addition, in adjusting the foam mixing ratio, since the air foam ratio is varied by adjusting the fire water flow rate in the prior art, there is an operational inconvenience in adjusting the air foam ratio according to the type of fire.
또한 요구되는 공기포비를 얻기 위해서 제어패널에서 소화수 유량 조절밸브의 개폐각을 조절하는 버턴을 수동으로 작업자가 눌러 요구된 공기포비를 얻을 때 까지 소요시간이 길고 사용상 불편함이 매우 많은 문제가 있다.In addition, in order to obtain the required air entrapment, the operator manually presses the button that adjusts the opening and closing angle of the fire extinguishing water flow control valve on the control panel, and the time it takes until the required air entrainment is obtained is long and there are many problems in use. .
또한 압축공기포 또는 소화수 방사 시 각각 별도의 라인을 사용하기 때문에 복수의 소방 호스 연결구(압축공기포 전용 소방호스연결구,소화수 전용 소방호스연결구)를 사용하고, 동일한 사유로 방수총은 소화수 전용으로만 사용이 가능한 문제도 있다.In addition, since separate lines are used when releasing compressed air bubbles or fire water, a plurality of fire hose connections (compressed air bubble fire hose connection port, fire hose connection port only for fire extinguishing water) are used, and for the same reason, the waterproof gun is used for fire extinguishing water. There is also the problem that it can only be used for exclusive use.
종래에는 압축공기포소화설비를 구동함에 있어서 소방차에 보관하고 있는 포소화약제를 모두 소진했을 경우에는 소화수만 공급하여 방사를 하도록 되어 있다.In the prior art, when all the fire extinguishing agents stored in the fire truck are exhausted in driving the compressed air fire extinguishing system, only fire extinguishing water is supplied to emit the fire.
그러나 종래에는 소화수로만 방사하는 경우 소화수의 공급 압력을 올려 방사거리를 확장하도돌 가고 있으나, 압력을 올려서 방사거리를 확장하려면 소화수 유량을 증가 시키지 않고는 거리를 확보 할수 없는 문제가 있었다.However, in the prior art, when only fire extinguishing water is radiated, the distance can not be secured without increasing the fire water flow rate in order to extend the radiation distance by increasing the supply pressure of fire water.
상기의 문제를 해결하기 위해, 본 발명의 목적은 하나의 소방호스 연결구를 사용하여 소화수 및 압축공기 포를 동시에 또는 선택적으로 사용함과 아울러 방수총을 통해 소화수 및 압축공기 포를 선택적으로 방사하도록 할 수 있는 압축공기 포 소화설비를 제공하는 것이다.In order to solve the above problem, an object of the present invention is to use a single fire hose connector to simultaneously or selectively use fire extinguishing water and compressed air bubbles, and to selectively radiate fire extinguishing water and compressed air bubbles through a waterproof gun. It is to provide a compressed air fire extinguishing system that can do this.
또한, 본 발명은 소화수 펌프, 공기 압축기 및 포 소화약제 공급펌프를 하나의 구동부를 통해 구동시킴과 아울러, 소화수 펌프 만을 선택적으로 구동시키도록 할 수 있는 압축공기 포 소화설비를 제공하는 것이다.In addition, the present invention is to provide a compressed air fire extinguishing system capable of driving a fire extinguishing water pump, an air compressor, and a fire extinguishing agent supply pump through one driving unit, and selectively driving only the fire extinguishing water pump.
또한, 본 발명은 서로 다른 공기포비 중 어느 하나를 선택하여, 포 수용액의 유량을 설정하고, 이 설정된 포 수용액의 유량을 이루기 위해 소화수의 유량 및 포 소화약제의 공급 유량을 제어하도록 할 수 있는 압축공기 포 소화설비를 제공하는 것이다.In addition, the present invention can select any one of the different air foam ratios, set the flow rate of the foam solution, and control the flow rate of the fire extinguishing water and the supply flow rate of the foam fire extinguishing agent to achieve the set flow rate of the foam solution It is to provide compressed air fire extinguishing equipment.
여기서 "포 수용액"이라 함은 포 소화약제와 소화수(물)을 혼합한 수용액이고, "공기포비"는 포 수용액과 압축공기를 혼합한 경우의 비율, 포 수용액에 대한 공급된 압축 공기량을 배수로 표시한 것이다.Here, "aqueous foam solution" refers to an aqueous solution in which a foam extinguishing agent and fire extinguishing water (water) are mixed, and "air foam ratio" refers to the ratio of the foam solution and compressed air mixed, and the amount of compressed air supplied to the foam solution as a multiple. it will be indicated
또한 본 발명은 소화수만을 방사하는 경우 공급되는 소화수에 압축공기를 공급하여 방사 거리를 일정 이상으로 확장할 수 있는 압축공기 포 소화설비를 제공하는 것이다.In addition, the present invention is to provide a compressed air fire extinguishing facility capable of expanding the radiation distance to a certain level or more by supplying compressed air to the supplied fire extinguishing water when only fire fighting water is radiated.
본 발명의 목적들은 이상에서 언급한 목적으로 제한되지 않으며, 언급되지 않은 본 발명의 다른 목적 및 장점들은 하기의 설명에 의해서 이해될 수 있고, 본 발명의 실시예에 의해 보다 분명하게 이해될 것이다. 또한, 본 발명의 목적 및 장점들은 특허 청구 범위에 나타낸 수단 및 그 조합에 의해 실현될 수 있음을 쉽게 알 수 있을 것이다.The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention not mentioned may be understood by the following description, and will be more clearly understood by the examples of the present invention. It will also be readily apparent that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the appended claims.
