도 1은 본 고안에 따른 검출 장치가 고로 냉각관에 설치된 상태의 개략도이고, 도 2는 본 고안에 따른 검출 장치의 사시도이며, 도 3은 본 고안에 따른 검출 장치의 단면도로서, 이를 참조하면 고로(10)의 풍구(12) 또는 노체를 냉각시키기 위한 냉각수가 이동하는 냉각관(20)의 끝단에 냉각관 파손을 검출하는 검출장치(A)가 설치되어 있고, 상기 검출 장치(A)는 냉각관(60)이 양측에 연결되는 케이스(20)의 전면에 압력계(22)와 온도계(24)가 설치되어 있고, 상기 케이스(20)의 상면에는 기체 포집통(30)이 설치되어 있으며, 이의 상단에는 수위 감지 센서(32)가 설치되어 있다.1 is a schematic view of a detection apparatus according to the present invention is installed in the blast furnace cooling tube, Figure 2 is a perspective view of the detection apparatus according to the present invention, Figure 3 is a cross-sectional view of the detection device according to the present invention, with reference to this A detection device (A) is provided at the end of the cooling tube (20) or the cooling tube (20) at which the coolant for cooling the furnace moves so as to detect damage to the cooling tube, and the detection device (A) is cooled. The pressure gauge 22 and the thermometer 24 are installed on the front surface of the case 20 to which the pipe 60 is connected to both sides, and the gas collecting vessel 30 is installed on the upper surface of the case 20. The water level sensor 32 is installed at the top.
그리고, 상기 수위 감지 센서(32)의 일측에는 가스 배출 밸브(34)가 설치되어 있고, 상기 케이스(20)의 내측에는 냉각수의 와류를 방지하기 위한 와류 방지판(40)이 설치되어 있으며, 상기 와류 방지판(40)에는 다수의 통공(42)이 형성되어 있다.In addition, a gas discharge valve 34 is installed at one side of the water level sensor 32, and a vortex preventing plate 40 is installed inside the case 20 to prevent vortex of the cooling water. The vortex breaker plate 40 is provided with a plurality of through holes 42.
한편, 상기 케이스(20)의 일측면 상부에는 전도도 센서(50)가 설치되어 있다.On the other hand, the conductivity sensor 50 is installed on the upper side of the side of the case 20.
상기와 같이 구성된 본 고안은 냉각수가 냉각관(60)으로 유입되어 풍구(12)와 노체를 순환하여 냉각시킨 후, 검출장치(A)를 통하여 배출된다.According to the present invention configured as described above, the cooling water flows into the cooling tube 60 to circulate the cooling holes 12 and the furnace body, and then is discharged through the detection device A.
이때 냉각관(60)이 파손되어 고로(10)내의 가스가 냉각관(60)으로 유입되면 상기 가스는 냉각수에 포함된 상태로 이동된다.At this time, when the cooling tube 60 is damaged and the gas in the blast furnace 10 flows into the cooling tube 60, the gas is moved to the state contained in the cooling water.
이때 상기 냉각수가 검출장치(A)의 케이스(10)내로 유입되면 상기 냉각수에 발생하는 와류는 와류 방지판(40)에 의해서 방지되며 상기 냉각수에 포함된 가스는 와류 방지판(40)의 통공(42)을 통해서 기체 포집통(30)의 상부로 이동하게 되므로 수위가 낮아지게 되어 수위 감지 센서(32)에서는 이를 감지하여 운전실의 작업자에게 알려 준다.At this time, if the cooling water is introduced into the case 10 of the detection device (A), the vortex generated in the cooling water is prevented by the vortex blocking plate 40 and the gas contained in the cooling water is formed through the opening of the vortex blocking plate 40 ( 42) is moved to the upper portion of the gas collecting container 30 through the water level is lowered so that the water level detection sensor 32 detects this and informs the operator of the cab.
이와 함께 케이스(20)의 전면에 설치된 압력계(22)의 압력과 온도계(24)의 온도가 낮아지게 되어 그 변화를 운전실의 작업자에게 경광등의 점등으로 알려주게 된다.Along with this, the pressure of the pressure gauge 22 installed on the front of the case 20 and the temperature of the thermometer 24 are lowered, thereby notifying the operator of the cab by turning on a warning light.
또한, 상기 냉각수에 포함되어 있는 가스는 케이스(20)의 일측면에 설치된 전도도 센서(50)에서 검출되며 기체 포집통(30)에 포집된 가스는 이의 상측에 설치된 가스 배출 밸브(34)를 개방 시키며 외부로 배출된다.In addition, the gas contained in the cooling water is detected by the conductivity sensor 50 installed on one side of the case 20, and the gas collected in the gas collecting container 30 opens the gas discharge valve 34 installed on the upper side thereof. It is discharged to the outside.
이상에서와 같이 본 고안은 냉각관의 파손시 상기 냉각관내 냉각수의 압력, 온도, 가스의 포함 정도를 검출하여 파손을 조기에 정확하게 검출하여 이로 인한 가스 누출을 방지하여 설비의 사용 수명을 연장시킬 수 있게 되는 효과가 있다.As described above, the present invention detects the pressure, temperature, and the degree of inclusion of the coolant in the cooling tube when the cooling tube is damaged, and accurately detects the damage early, thereby preventing the leakage of gas, thereby extending the service life of the facility. It is effective to be.
