Description

포소화액 혼합분사장치{Mixing and scattering apparatus for fire control foam liquid}[0002] Mixing and scattering apparatus for fire control foam liquid [

본 발명은 포소화액 혼합분사장치에 관한 것으로서, 포소화액을 물과 혼합하는 과정에서 물의 유량을 손쉽게 조절하여 포소화액과 적절하게 혼합될 수 있으면서 분사시 포소화혼합액의 토출속도 및 거품의 발생을 원활하도록 하는 포소화액 혼합분사장치에 관한 것이다.
The present invention relates to a mixed liquid spraying apparatus of a foam liquid, which can easily adjust the flow rate of water during the mixing of the foam liquid with water, so that it can be mixed with the foam liquid appropriately, To the mixed liquid spraying device.

일반적으로 화재 발생시 포소화액과 물을 혼합하여 소화작업을 하게 된다. 이때 사용되는 기존의 소화장치는 특별한 장치 없이 포소화액과 물을 단순 혼합하여 구비한 혼합액 탱크에 배관 및 펌프를 연결하여 펌프의 압으로 배관을 통해 포소화혼합액을 분사하도록 하고 있다.Generally, in case of fire, digestion works by mixing water and water. In the existing fire extinguishing system used, the piping and the pump are connected to the mixed liquid tank by simply mixing the foamed liquid and the water without any special device, and the foamed mixture is sprayed through the piping by the pressure of the pump.

이러한 종래의 포소화액의 혼합 방식은 화재발생 조건에 따라 포소화액과 물의 혼합비를 조절하기 곤란하며, 상황에 따라 그 혼합비를 즉시 조절하기 힘든 문제점이 있었다. 또한 이러한 종래의 포소화액 분사 방식은 물과 혼합된 포소화액을 그대로 토출시켜 사용하는 것으로서 위와 마찬가지로 화재발생 조건에 관계 없이 정해진 조건으로만 분사할 수 밖에 없게 된다.It is difficult to control the mixing ratio of the water to be floated with water according to the fire generation condition and it is difficult to control the mixture ratio immediately according to the situation. In addition, the conventional spraying method of the liquid fuels is used to discharge the foamed liquid mixed with water as it is, and it is forced to spray only under predetermined conditions regardless of the fire occurrence condition.

이로 인해 포소화액의 불필요한 과낭비 및 소화작업시간을 증가시키게 될 수 있다.This may lead to unnecessary waste of the filler fluid and increase the duration of the extinguishing operation.

뿐만 아니라, 포소화액에 의해 탱크 및 펌프의 부식이 단시간에 초래되어 유지비 및 교체비가 많이 드는 문제점이 있었다.
In addition, the corrosion of the tank and the pump is caused in a short time by the foamed liquid, which causes a problem of a large maintenance cost and replacement cost.

도 1 내지 도 9를 참조하여 보면 본 발명에 의한 포소화액 혼합분사장치는 물탱크(2)에 연결설치된 펌프(3)에 연결되는 직관 형태의 메인관(10)과, 메인관(10) 상을 우회하여 합류하는 서브관(20)으로 구성되어 이루어진다.1 to 9, the mixed liquid spraying apparatus according to the present invention includes a main pipe 10 in the form of an inturn pipe connected to a pump 3 connected to a water tank 2, And a sub-tube 20 for bypassing and merging.

상기 메인관(10)은 도 3에서와 같이 일측단부에 상기 펌프(3)로부터의 물이 공급이동되는 물유입부(11)가 형성되고, 중간부에 포소화액유입부(13)가 형성되며, 타측단부에 물과 포소화액의 혼합액토출부(15)가 형성되고, 포소화액유입부(13)와 혼합액토출부(15)의 사이에 역류방지체크밸브(17)가 형성된다.3, the main pipe 10 is provided at one end thereof with a water inlet 11 through which the water from the pump 3 is supplied and moved, and a filler inlet 13 is formed at the middle thereof And a check valve 17 is provided between the fluid inlet 13 and the mixed liquid outlet 15. The check valve 17 is provided at the other end.

상기 메인관(10)의 물유입부(11)를 통해 소화를 위해 펌프(3)로부터 공급되는 물이 유입되고, 포소화액유입부(13)를 통해 소화를 위한 포소화액이 유입되며, 물과 포소화액이 부딪혀 혼합되는 메인관(10)의 내부에는 물과 포소화액이 혼합된 혼합액의 유속을 증대시키면서 압을 높여주는 벤츄리부(31)를 형성한다.Water supplied from the pump 3 flows through the water inlet 11 of the main pipe 10 to enter the digester 10 through the funnel inlet 13, A venturi portion 31 is formed in the main pipe 10 in which the foamed liquid is mixed and mixed to increase the pressure of the mixed liquid in which water and the foamed liquid are mixed.

본 발명은 포소화액을 물과 미리 혼합하여 탱크에 저장해 두는 것이 아니라, 상술된 바와 같이 포소화액과 물이 혼합되는 포소화액 혼합분사장치를 물탱크(2)에 연결설치된 펌프(3)의 토출라인에 설치함으로써 포소화액이 물탱크(2) 및 펌프(3)에 부식에 대한 영향을 끼치지 않도록 한 것이다.The present invention is not limited to a method in which the flocculant liquid is mixed with water and stored in the tank but the flocculant liquid mixing apparatus in which the flocculant liquid and the water are mixed as described above is discharged from the discharge line of the pump 3 connected to the water tank 2 So that the flooding liquid does not affect the water tank 2 and the pump 3 against corrosion.

상기 벤츄리부(31)는 도 4의 (a)에서와 같이 통상의 것으로 형성할 수 있고, 그 변형예로서 도 4의 (b)에서와 같이 유입측에는 유입되는 물이 부딪혀 물분자가 파쇄되면서 포소화액과의 혼합이 원활하게 이루어지도록 수직 단턱지게 형성하고, 배출측은 유속이 증대되면서 고압분사되도록 확장형으로 형성되게 할 수 있다.As shown in Fig. 4 (b), the venturi portion 31 may be formed as a normal one as shown in Fig. 4 (a). In this variation, as the water molecules collide with the inflowing water, And the discharge side can be formed in an expanded shape so as to be injected at a high pressure while the flow velocity is increased.

한편, 상기 서브관(20)은 도 3에서와 같이 상기 메인관(10) 상에서 물유입부(11)와 포소화액유입부(13)의 사이에서 연결되어 물이 우회하고, 포소화액유입부(13)와 역류방지체크밸브(17) 사이에서 연결되어 물이 합류하며, 중간부에 물의 유량을 조절하는 유수량조절밸브(22)가 구비되도록 구성된다.3, the sub tube 20 is connected between the water inlet 11 and the encapsulation fluid inlet 13 on the main tube 10 to bypass the water, 13) and a check valve (17) for collecting water, and a flow rate control valve (22) for controlling the flow rate of water in the middle part.

상기 서브관(20)을 통해서는 메인관(10)의 유입부(11)를 통해 유입되는 물만 유동되며, 서브관(20) 상에 구비되는 유수량조절밸브(22)를 통해 물의 유입량이 조절된다.Only the water flowing through the inlet 11 of the main pipe 10 flows through the sub pipe 20 and the inflow amount of water is regulated through the flow amount control valve 22 provided on the sub pipe 20 .

이때 유수량조절밸브(22)를 구비하는 것은, 상기 메인관(10)의 벤츄리부(31)를 통해 배출되는 물 및 포소화액의 혼합액의 량은 배출압을 높이기 위해 공간을 좁혀 구성하게되므로 그 만큼 배출량이 적을 수 밖에 없게 된다. 그 적은 배출량을 보충하기 위해 메인관(10)을 우회하여 합류하는 서브관(20)을 구비한 것이며, 유수량조절밸브(22)를 통해 보충수를 공급함으로써 물량조절 및 혼합액의 양을 조절하도록 한 것이다.At this time, since the amount of the mixture of water and the foamed liquid discharged through the venturi portion 31 of the main pipe 10 is narrowed in order to increase the discharge pressure, the flow control valve 22 is provided. The amount of emissions is inevitably low. And a sub-pipe 20 which bypasses the main pipe 10 to compensate for the small amount of emission, and the amount of water to be adjusted and the amount of the mixed liquid are adjusted by supplying supplemental water through the flow-rate control valve 22 will be.

상기한 구성의 메인관(10) 및 서브관(20)은 도 1 및 도 2에서와 같이 이동 및 사용이 용이하도록 뚜껑(2)을 갖는 박스 형태의 수용체(3) 내에 구비되도록 함이 바람직하다.The main pipe 10 and the sub pipe 20 having the above-described configuration are preferably provided in a box-shaped receptacle 3 having a lid 2 so as to be easily moved and used as shown in Figs. 1 and 2 .

이의 사용을 위해서 상기 메인관(10)의 혼합액토출부(15)에는 호스(50)의 일측이 연결되고, 호스(50)의 타측에 분사노즐(40)이 연결 구성된다. 이때 분사노즐(40)은 도 6 및 도 7에서와 같이 내측에 형성된 관통로(41) 상의 중간부에 이동되는 혼합액이 충돌되어 파쇄되는 수직단턱부(43)가 형성되고, 관통로(41) 상의 수직단턱부(43) 전방측 또는 후방측에 외부와 연통되어 공기가 유입되게 함으로써 혼합액 거품이 발생하도록 다수의 공기유입공(45)이 형성되어 구성된다.One end of the hose 50 is connected to the mixed liquid discharge portion 15 of the main pipe 10 and the injection nozzle 40 is connected to the other side of the hose 50 for use. 6 and 7, the injection nozzle 40 is formed with a vertical step portion 43 in which the mixed liquid moving in the intermediate portion on the inner side of the through path 41 is collided to collapse, A plurality of air inflow holes 45 are formed in the front side or rear side of the vertical step portion 43 on the upper surface of the vertical step portion 43 so as to communicate with the outside to allow air to flow therein,

상기한 분사노즐(40)의 구조는 거품이 많이 발생되지 않고 고압직진성을 가지므로 원거리 사용에 적합하며, 도 8 및 도 9에서와 같이 분사노즐(40)의 배출측 단부에 혼합액확산부재(49)를 구비하되, 분사노즐(40)의 통로(41) 내측에 위치되는 후방측부는 꼭지점이 후방을 향하는 원뿔 형태로 형성되게하여 토출되는 혼합액이 꼭지점을 갖는 혼합액확산부재(49)에 의해 확산되면서 거품발생량을 증대시킴으로써 근거리 사용에 적합하도록 할 수 있다.
The structure of the injection nozzle 40 described above is suitable for long-distance use because it does not generate much bubbles and has high-pressure straightness. The structure of the injection nozzle 40 is similar to that of the mixed liquid diffusion member 49 And the rear side portion located inside the passage 41 of the injection nozzle 40 is formed into a conical shape with the vertex pointed backward while being diffused by the mixed liquid diffusion member 49 having the vertexes By increasing the amount of bubble generation, it can be made suitable for short-distance use.
