본 고안은 화염 역화 방지장치에 관한 것으로 보다 상세히는 아연도금처리설비의 가열로 설비에서 가스공급라인의 일단부에 장착됨으로서, 화염역화로 인한 고압발생으로 가스공급라인이 파손되고, 인접한 타 버너장치가 소화되는 것을 방지할 수 있는 화염역화 방지장치에 관한 것이다The present invention relates to an apparatus for preventing flame backfire, and more particularly, it is installed at one end of a gas supply line in a furnace facility of a galvanizing treatment facility. To prevent flame backfire from being extinguished
일반적으로 제철소의 아연도금설비(200)는 제1도와 제2도에 도시한 바와갈이, 강판(9)을 가열하면서 통과시킬 수 있는 가열로(210)를 갖추며, 상기 가열로(210)을 통과한 강판(9)은 연속적으로 아연도금조(220)를 통과하도륵 구성된다. 그리고, 아연도금조(220)의 상부에 설치된 에어나이프 장치(230)의 에어압력에 의해서 강판(9) 표면에 부착된 아연도금량이 수요가의 요구부착량만큼 조절되며, 상기 공정을 거친 강판(9)은 냉각장치(240)에 의하여 냉각처리된 후에 다음공정으로 진헝되는 것이다.In general, the galvanizing equipment 200 of the steel mill is provided with a heating furnace 210 through which the steel sheet 9 can pass while heating the steel sheet 9 as shown in FIGS. 1 and 2. The steel sheet 9 passed is configured to pass through the galvanizing bath 220 continuously. In addition, the amount of zinc plating attached to the surface of the steel sheet 9 is adjusted by the required attachment amount of the demand by the air pressure of the air knife device 230 installed on the upper part of the galvanizing tank 220, and the steel sheet having undergone the above process (9). ) Is cooled to the next step after being cooled by the cooling device 240.
그리고, 상기 가열로(200)의 내부에는 진행되는 강판(9) 표면에 아연도금이 잘 부착할 수 있도록 적정온도, 대략 450 내지 470도 정도로 가열해주기 위해서, 다수개의 편향롤(211)과 약 150개 정도의 버너장치(100)를 설치하여 직, 간접적으로 상기 강판(9)을 가열하는 것이다. 이리한 상기 버너장치(100)는 가스공급라인(120)의 일단부에 장착되는 버너관(101)과 화염이 분사되는 슬랙(103) 사이에 믹서박스(102)를 갖추며, 상기 믹서박스(102)에는 에어공급관(110)이 연결되고, 점화장치를 갖추고 있다.In addition, a plurality of deflection rolls 211 and about 150 are heated in a temperature of about 450 to 470 degrees at an appropriate temperature so that zinc plating can be adhered to the surface of the steel sheet 9 that is advanced in the heating furnace 200. The burner apparatus 100 of about a degree is installed, and the said steel plate 9 is heated directly or indirectly. The burner device 100 is provided with a mixer box 102 between the burner tube 101 mounted at one end of the gas supply line 120 and the slag 103 to which the flame is injected, and the mixer box 102. ) Is connected to the air supply pipe 110, and is equipped with an ignition device.
한편, 상기 버너장치(100)가 장착되는 버너관(101)은 다수개의 가스공급라인(120)에 각각 연결되고, 상기 가스공급라인(120)은 C.O.G.(Coke Over Gas)가 공급되는 메인가스라인(130)의 일측에 다수개 갖추는 한편, 상기 가스공급라인(120)상에는 차단밸브(Shut-Off Valve)(121)와 유체제어밸브(Flow Control Valve)(122)를 갖춘다. 그리고, 상기 메인가스라인(130)과 가스공급라인(120)의 각 일단부에는 밀패용 플랜지(120a), (130a)로서 각각 막음질을 한다.On the other hand, the burner pipe (101) on which the burner device (100) is mounted is connected to a plurality of gas supply lines (120), respectively, and the gas supply line (120) is a main gas line supplied with COG (Coke Over Gas). On the one side of the 130 is provided with a plurality, on the gas supply line 120 is provided with a shut-off valve (Shut-Off Valve) 121 and the flow control valve (Flow Control Valve) (122). Then, one end of each of the main gas line 130 and the gas supply line 120 is blocked by the sealing flanges (120a, 130a), respectively.
따라서, 상기 버너장치(100)로 C.O.G.가스를 공급하기 위해서는 직접제어시스템(Direct Control System; 이하 D.C.S라 칭함)단말기(미도시)를 통하여 차단밸브(121)를 개방하여 가스유량을 설정한후에, 유체제어밸브(122)를 열도록 하여 상기 C.O.G.가스를 버너관(101)으로 공급하고, 에어공급관(110)과 연결된 믹서박스(102)에서 상기 C.O.G.가스와 에어가 혼합되어 슬랙(103)의 단부로 흐르게 한다.Therefore, in order to supply the COG gas to the burner device 100, after opening the shutoff valve 121 through a direct control system (hereinafter referred to as DCS) terminal (not shown) to set the gas flow rate, the fluid The control valve 122 is opened to supply the COG gas to the burner tube 101, and the COG gas and air are mixed in the mixer box 102 connected to the air supply pipe 110 to the end of the slag 103.

이하, 본 고안에 따른 화염역화 방지장치의 작용 및 효과에 대해서 상세히 설명한다.Hereinafter, the operation and effects of the flame arrest apparatus according to the present invention will be described in detail.
즉, 상기와 같이 구성된 화염역화 방지장치(1)는 버너장치(100)의 작동중 역화현상이 발생하여 버너관(101)에 고압이 형성되면, 상기 버너관(101)의 일단에 장착된 스틸배관(11)에 압력을 가하게 됨으로서, 상기 스틸배관(11)의 연결플랜지(12) 사이에 장착된 스텐레스 가스켓(13)이 폭발됨과 동시에, 상기 스틸배관(11)의 상부에 장착된 원형뚜껑(19)이 상방으로 순간적으로 올려지게 되는 것이다. 이때, 상기 원형뚜껑(19)의 고정고리(17)에 연결되는 작동막대(23)가 힌지고리(21)를 회전축으로 상방으로 올려져, 상기 작동막대(23)의 타단부에 장착된 작동추(22)가 올려지는 것이다.That is, the flame backfire prevention device 1 configured as described above has a backfire phenomenon during operation of the burner device 100, and when the high pressure is formed in the burner pipe 101, the steel mounted on one end of the burner pipe 101 is provided. By applying pressure to the pipe 11, the stainless steel gasket 13 mounted between the connecting flange 12 of the steel pipe 11 is exploded, and at the same time, a circular lid mounted on the top of the steel pipe 11 ( 19) is instantaneously raised upwards. At this time, the operating rod 23 connected to the fixing ring 17 of the circular lid 19 is raised to the hinge ring 21 upward by the rotation axis, the operating weight mounted on the other end of the operating rod 23 (22) is raised.
이러한 상기 작동막대(23)의 힌지작동으로 인해서, 연결고리(32)의 힌지핀(32a)에 연결된 작동편(31)의 일단부를 누르고 있던 상기 작동추(22)가 올려져 그 외력이 해제됨으로서, 상기 작동편(31)의 타단부에 와이어로프(33)로 연결된 무게추(36)가 자중(自重)에 의해서 하향으로 낙하가 이루어지는 것이다. 이때, 하향되는 상기 무게추(34)가 원형스틸(37)에 장착된 터치센서(35)를 감지하고, 상기 터치센서(35)로서 감지한 신호를 D.C.S.단말기로 전송하여 가스공급라인(120)에 설치된 차단벨브(121)와 유체제어밸브(122)를 닫아줌으로서, 버너장치(100)로의 C.O.G 가스 공급을 차단하여 상기 버너장치(100)의 적절한 소화를 수행할 수 있는 것이다.Due to the hinge operation of the operating rod 23, the operating weight 22, which was holding down one end of the operating piece 31 connected to the hinge pin 32a of the connecting ring 32, is lifted and the external force is released. The weight 36 connected to the other end of the operation piece 31 by the wire rope 33 falls downward due to its own weight. At this time, the downward weight 34 detects the touch sensor 35 mounted on the circular steel 37, and transmits the signal detected as the touch sensor 35 to the DCS terminal to supply the gas supply line 120 By closing the shutoff valve 121 and the fluid control valve 122 installed in, it is possible to block the COG gas supply to the burner device 100 to perform the appropriate fire extinguishing of the burner device (100).
한편, 소화된 버너장치(100)의 재점화를 위해서는 연결플랜지(12)를 분해한 후에, 버너장치의 역화로 인하여 파손된 스텐레스 가스켓(13)을 교환하고, 상기 작동편(31)의 일단부에 작동추(22)를 올려놓음으로서, 상기 작동추(22)의 외력에 의하여 감지부(30)의 터치센서(35)로 부터 무게추(34)를 서로 이격시킴으로서, D.C.S.단말기로 부터 차단밸브(121)와 유체제어밸브(122)에 버너장치(100)에 C.O.G.가스를 공급하도록 신호를 보내어 상기 버너장치(100)의 재점화를 수행할 수 있는 것이다.Meanwhile, in order to re-ignite the burned burner device 100, after disassembling the connection flange 12, the stainless gasket 13, which is damaged due to the backfire of the burner device, is replaced, and one end of the operation piece 31 is replaced. By placing the actuating weight 22 on, by separating the weight 34 from the touch sensor 35 of the sensing unit 30 by the external force of the actuating weight 22, the shutoff valve from the DCS terminal The burner device 100 may be re-ignited by sending a signal to supply the COG gas to the burner device 100 at the 121 and the fluid control valve 122.
따라서, 본 고안에 따른 화염역화 방지장치(1)에 의하면, 버너관(101)에 고압이 걸리는 화염역화 현상이 발생할때, 힌지작동하는 작동부(20)의 동작을 감지하는 감지부(30)의 터치센서(35)에 의해서 D.C.S.단말기를 제어함으로서, 버너관(101)에 고압이 걸리는 것을 방지하여 설비파손 및 대형사고를 예방할 수 있으며, 인접한 타 버너장치(100)를 소화시키는 것을 방지할 수 있는 실용상의 효과가 있다.Therefore, according to the flame backfire prevention device 1 according to the present invention, when the flame backfire phenomenon occurs that the high pressure is applied to the burner tube 101, the sensing unit 30 for detecting the operation of the hinge operation unit 20 By controlling the DCS terminal by the touch sensor 35, it is possible to prevent the high pressure is applied to the burner tube 101 to prevent equipment damage and large accidents, and to prevent extinguishing of other adjacent burner device 100. It has a practical effect.
