Description

물안개분사 소화용 노즐{water mist spray nozzle}Water mist spray nozzle

본 발명은 노즐에 관한 것으로, 더욱 상세하게는 소화용 약재로 물을 사용하되, 분사되는 물입자를 최소화 시키고 저압하에서도 안개형상으로 물을 분사시켜 안개의 침투력 및 공기차단력을 이용하여 일반화재 및 유류화재도 진압시키는 물안개분사 소화용 노즐에 관한 것이다.The present invention relates to a nozzle, and more specifically, to use water as a fire extinguishing agent, to minimize the water particles to be sprayed and to spray water in the form of fog even under low pressure by using the fire penetration force and air blocking force of the fog and general fire and The present invention relates to a nozzle for extinguishing water fog, which also suppresses an oil fire.

일반적으로 화재가 발생되는 경우 소방차가 출동하든지 소화기를 이용하여 화재를 진압하게 된다.In general, when a fire occurs, a fire truck or a fire extinguisher is used to extinguish a fire.

통상의 화재진압을 위해서는 소화용 약재로 물을 사용하게 되며 소화용 약재로 물을 사용하는 방식에는 스프링쿨러를 이용하는 방법과 물분무설비를 이용하는 방법 등이 있다.For fire extinguishing, water is used as a fire extinguishing agent, and water is used as a fire extinguishing agent using a sprinkler and a water spraying facility.

종래기술에 따른 스프링 쿨러를 이용하는 방법에는 스프링 쿨러헤드를 설치하여 스프링 쿨러헤드를 통하여 소정의 물이 분사되는 방식으로 크게 건식형과 습식형으로 구분된다.The method using a sprinkler according to the prior art is largely divided into a dry type and a wet type by installing a sprinkler head and spraying predetermined water through the sprinkler head.

건식형은 스프링쿨러 헤드의 공급배관과 헤드에는 물이비워져 있으며 화재감시기의 작동으로 수신반에 경보가 발생한 후에 소방 급수펌프가 자동 또는 수동동작에 의해 소방차의 송수구에 연결되고 소방차의 급수에 의한 살수로 화재를 소화하게 된다. 여기서 통상 1개의 스프링쿨러의 헤드에서는 분당 80리터의 물이 살수된다.In the dry type, water is emptied in the supply pipe and head of the sprinkler head, and after the alarm on the receiving panel is triggered by the fire monitor, the fire water supply pump is connected to the fire truck's water inlet by automatic or manual operation, Extinguish fire. Here, typically, 80 liters of water per minute are sprinkled from the head of one sprinkler.

습식형은 스프링쿨러 헤드에 열팽창 유리관 퓨즈나 열을감지한 후 녹아내리는납퓨즈가 헤드분사구를 막고 있으며, 공급배관에는 물이 채워져서 일정압력을 유지하고 있다. 화재시에는 스프링쿨러 헤드의 퓨즈가 열을받은 후에 떨어져나가면서 헤드를 통하여 물이 살수된다. 여기서 통상 스프링 쿨러의 헤드에 분당 80리터의 물이 살수된다.In the wet type, the thermal expansion glass tube fuse or heat fuse melted after detecting heat in the sprinkler head blocks the head injection port, and the supply pipe is filled with water to maintain a constant pressure. In a fire, water is sprayed through the head as the sprinkler head fuses off after it receives heat. Here, 80 liters of water are sprinkled onto the head of a sprinkler.

그러나 상기의 종래기술은 후술하는 문제점이 있다.However, the above prior art has a problem described below.

첫째, 상기 스프링쿨러 헤드를 통해 물입자가 분사되므로 유류화재 등에는 사용이 불가능하다.First, since water particles are injected through the sprinkler head, it is impossible to use the oil fire.

둘째, 소화시 사용되는 물의 양이 과다하며, 다량의 물분사로 인한 2차적 피해 즉, 침수, 전기사고 등의 문제점이 있다.Second, the amount of water used for extinguishing is excessive, there are problems such as secondary damage due to a large amount of water spray, that is, flooding, electrical accidents.

셋째, 자동화설비의 고압방식 즉, 많은 물을 소모하는 기존의 노즐을 이용하여 물을 장거리로 보내려면 별도의 물탱크와 고압펌프가 필요하다는 문제점이 있다.Third, there is a problem that a separate water tank and a high pressure pump are required to send water over a long distance by using a high pressure method of the automation equipment, that is, a conventional nozzle that consumes a lot of water.

따라서, 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로, 소화용 약재로 물을 사용하되, 분사되는 물입자를 최소화 시키고 저압하에서도 안개형상으로 물을 분산 분사시켜 안개의 침투력 및 공기차단력을 이용하여 일반화재 및 유류화재도 진압시키는 물안개분사 소화용 노즐을 제공하는 것을 목적으로 한다.Therefore, the present invention has been devised to solve the above problems, using water as a fire extinguishing agent, to minimize the water particles to be injected and to spray the dispersion of water in the form of fog even under low pressure to improve the penetration and air blocking force of the fog It is an object of the present invention to provide a nozzle for extinguishing water fog spraying to extinguish general fire and oil fire.

Then, the external water supply pipe is coupled to the coupling portion 102 of the water inflow member 110.

그런 다음 상기 외부 물공급관에서 물이 공급된다. 여기서 상기 물의 공급압력은 10∼15kgf/cm2정도를 유지한다. 공급된 물은 상기 물유입부재(100)의 내부에형성된 안내유로(101)를 따라 물수용부재(110) 내부로 유입된다. 상기 물수용부재(110)로 유입된 물은 상기 물수용부재(110)의 내부에 형성된 수용부(113)로 유입되어 상기 수용부(113)측으로 돌출된 압력발생부재(120)의 외주면을 따라 회전 즉, 와류되면서 소정의 회전력 및 가속도가 생성된다. 상기 수용부(113)에서 와류되는 물은 각지점마다 동일한 흐름상태를 유지하고 압력도 각지점마다 동일한 상태를 유지한다. 수용부(113)에서 와류되던 물은 소정의 출입구로 배출되어야 하는 바, 상기 압력발생부재(120)에 형성된 물유입공(122)을 통하여 상기 압력발생부재(120) 내부로 유입된다.Then water is supplied from the external water supply pipe. Wherein the water supply pressure is maintained about 10 to 15kgf / cm 2 . The supplied water is introduced into the water receiving member 110 along the guide passage 101 formed in the water inflow member 100. Water introduced into the water receiving member 110 flows into the receiving portion 113 formed inside the water receiving member 110 and along the outer circumferential surface of the pressure generating member 120 protruding toward the receiving portion 113 side. Rotation, i.e., vortexing, generates the desired rotational force and acceleration. The water vortexed in the receiving portion 113 maintains the same flow state at each point and the pressure also maintains the same state at each point. Water vortexed in the receiving part 113 should be discharged to a predetermined entrance and exit, and is introduced into the pressure generating member 120 through a water inlet hole 122 formed in the pressure generating member 120.

이 과정에서 압력발생부재(120) 내부로 유입되는 물에는 소정의 압력이 형성된다. 그리고 상기 압력발생부재(120) 내부로 유입된 물은 상기 압력발생부재(120)의 내주면을 따라 와류형상으로 회전하게 되며, 상기 와류에 의해 상기 압력발생부재(120)에 내부의 물은 위치에 관계없이 동일한 압력을 유지하게 되고, 물분자간의 결합력이 줄어들게된다. 즉, 물분자의 응집력이 줄어들게 된다. 상기 압력발생부재(120)의 내부에서 와류되던 물은 상기 압력발생부재(120)의 하부에 형성된 분사구(133)를 통하여 외부로 유출분사되며 상기 분사구(133)의 하부에 형성된 확장부(134)를 거치면서 방사상의 안개형상으로 퍼져나간다.In this process, a predetermined pressure is formed in the water flowing into the pressure generating member 120. And the water introduced into the pressure generating member 120 is rotated in a vortex shape along the inner peripheral surface of the pressure generating member 120, the water inside the pressure generating member 120 by the vortex in the position. Irrespective of the same pressure, the binding force between the water molecules is reduced. That is, the cohesion of water molecules is reduced. Water that was vortexed inside the pressure generating member 120 is sprayed to the outside through the injection hole 133 formed in the lower portion of the pressure generating member 120, and the expansion part 134 formed in the lower portion of the injection hole 133. As it passes through, it spreads in a radial fog shape.

이때 상기 분사구(133)를 통하여 분사되는 분사압력은 상기 압력발생부재(120)의 내부에서 이루어진 물의 와류에 의해 항상 일정한 값을 유지하게 되며, 압력은 대략 10∼15kgf/cm2정도이다. 그리고 상기 압력발생부재(120) 내부에서의 와류에 의해 물이 응집력이 약화되어 안개형상으로 분사되며 상기 안개입자크기는 레이저 분광기로의 입자크기 측정결과 80∼250 micron 정도되며, 분사량은 6∼8ℓ/min 이고, 분사각은 80°∼120°정도이며, 분사거리는 약 4m정도를 유지한다.At this time, the injection pressure injected through the injection port 133 is always maintained a constant value by the vortex of water made in the pressure generating member 120, the pressure is about 10 ~ 15kgf / cm 2 or so. Water is weakened by the vortex inside the pressure generating member 120, and the water is weakened and sprayed in a fog shape. / min, the injection angle is about 80 ° ~ 120 °, and the injection distance is about 4m.

상기의 구성에 의한 본 발명은, 첫째 소화약재로 물을 이용하면서도 일반화재 및 유류화재도 소화할 수 있다는 효과가 있다.The present invention by the above configuration, the first fire extinguishing agent has the effect of being able to extinguish general fires and oil fires while using water.

둘째, 노즐을 통하여 안개입자로 분사되므로 화원에 접근하여 안개상태엣 증기로 변화는 과정이 순간적으로 이루어지므로 최소한 538kcal의 열량을 순간적으로 뺏어가므로 물보다는 훨씬 많은 열량을뺏어가게 되어 화재진압능력이 탁월한 효과가 있다.Second, since it is sprayed into the mist particles through the nozzle, the process changes to the steam at the fog state, and the process takes place instantaneously, so it takes at least 538 kcal of heat momentarily and takes much more heat than water, so the fire suppression ability Excellent effect

셋째, 화재진압시 화재부분은 산소의 결핍으로 인해 기압이 낮아지는 바, 안개입자 형태로 분사된 분사물이 기압이 낮은쪽으로 자연스럽게 이동되어 화재의 측면진압이 가능하다는 효과가 있다.Third, when the fire is extinguished, the pressure of the fire is lowered due to the lack of oxygen, so that the spray injected in the form of mist particles is naturally moved toward the lower air pressure, thereby making it possible to extinguish the side of the fire.

넷째, 안개입자가 유동성 매연 및 분진등을 포집하여 바닥으로 가라앉히므로 매연 및 분진등에 의한 피해를 최소화시킨다.Fourth, since the mist particles trap the fluid soot and dust to sink to the floor to minimize the damage caused by soot and dust.

다섯째, 사용되는 물의 양을 최소화시킴에 의해 2차적인 침수피해 및 전기누수에 의한 감전사고 등을 방지 할 수 있다는 효과가 또한 있다.Fifthly, by minimizing the amount of water used, there is also an effect that can prevent secondary flooding damage and electric shock due to electrical leakage.
