제2도는 가스 채취구 정단면도.2 is a front cross-sectional view of the gas collecting port.

제3도는 가스 채취구의 평면도.3 is a plan view of the gas collection port.

본 고안은 고로의 연소대의 가스 채취장치에 관한 것으로 특히, 가스 유도로와 냉각수 유입로, 냉가수 배출로로서 3중관으로 구성되고 이 3중관의 전단 일측에 유입방판 및 가스누출공을 형성한 가스 채취구가 나사로 맞춤되어서 되는 고로 연소대의 가스 채취장치에 관한 것이다. 고로의 연소대는 로정에서 장입된 코크스(Coke)가 풍구로 송입된 열풍중의 산소와 반응하여 열원을 공급하고 철광석의 환원반응에 필요한 환원성 가스를 공급하며 장입물 제어분포에 영향을 주는 중요한 영역이다. 또한 고로의 연소대는 온도와 압력이 높고 용융상태의 철과 슬래그 및 고온의 코크스가 고속의 열풍에 의해 심한 운동에너지(Energy)를 받아 맹열히 움직이고 있는 곳이다.The present invention relates to a gas collecting device of a blast furnace combustion gas, in particular, a gas induction furnace, a cooling water inlet passage, a cold water discharge passage consisting of a triple pipe, the gas formed inlet valve and gas leak hole on the front end of the triple pipe The present invention relates to a gas collection device of a blast furnace combustion table in which a collecting port is screwed. The blast furnace's combustion zone is an important area in which coke charged from the furnace is reacted with oxygen in the hot air fed into the vents to supply heat sources, supply reducible gases for iron ore reduction reactions, and affect the load control distribution. . In addition, the combustion zone of the blast furnace is a place where high temperature and pressure, molten iron and slag, and high temperature coke are moved violently by severe kinetic energy by high-speed hot air.

이러한 악조건에서 가스를 채취하는 장치는 용손 및 막힘이 빈번하여 채취에 어려움이 있었다.Gas collecting device under such bad condition has difficulty in collecting because of frequent melting and clogging.

본 고안은 이러한 문제점을 해결한 고안으로 첨부도면에 의해 설명하면 다음과 같다.The present invention is described by the accompanying drawings as a design that solves these problems are as follows.

본 장치의 프레임(1)은 3중관으로 되어 있다. 즉, 제일중앙에 가스유도로(2), 다음에는 냉각수 유입관(4), 맨가장자리에 냉각수 배출관(5)으로 되어 있다.The frame 1 of this apparatus is a triple tube. That is, the gas flow path 2 at the first center, the cooling water inlet pipe 4, and the cooling water discharge pipe 5 at the edge thereof.

또한 가스유도로 (2)에는 유도로보호관(3)을 삽입할 수 있게 하였으며 프레임(1)의 전단부에는 하방으로 교환이 가능하도록 가스채취구(6)를 나착하되, 가스채취구 내벽에 용융물 유입방지판(7)을 서로 어긋나게 부착하였으며 상단에는 가스흡입공(8)을 천공하여, 가스채취구(6)를 프레임(1)에 나착시키면, 가스흡입공(8)이 뚫린 부분이 가스유도로(2)와 직교되도록 하였다. 미설명 부호 8'는 유도로 보호관(3)에 천공된 가스흡입공이며, 9는 냉각수, 10는 가스를 표시하였다.In addition, the induction furnace protection tube (3) can be inserted into the gas flow path (2), and the gas collecting port (6) is attached to the front end of the frame (1) so that it can be exchanged downward, but the melt is formed on the inner wall of the gas collecting port. When the inflow prevention plate 7 is attached to each other and the gas suction hole 8 is drilled on the upper end, and the gas collecting hole 6 is attached to the frame 1, the portion where the gas suction hole 8 is drilled is induced to gas. Orthogonal to the furnace (2). Reference numeral 8 'denotes a gas suction hole drilled in the induction furnace protection tube 3, 9 denotes a cooling water, and 10 denotes a gas.

이상과 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

고로의 연소대에 본 장치의 프레임(1)을 수평으로 삽입하되 가스채취구(6)가 하방을 향하게 하고, 냉각수 유입관(4)을 통해 냉각수(9)를 5∼6㎏/초 정도로 윱입시킨다. 유입된 냉각수는 프레임(1)의 전단부를 통하여 냉각수 배출관(5)으로 배출되며 연소대에서 받은 열을 흡수하여 배출하므로 프레임(1)의 용손을 방지한다.Insert the frame (1) of the device horizontally into the furnace of the blast furnace, with the gas collection port (6) facing downward, and the cooling water (9) through the cooling water inlet pipe (4) about 5 to 6 kg / second Let's do it. The introduced cooling water is discharged to the cooling water discharge pipe 5 through the front end of the frame 1 and absorbs and discharges the heat received from the combustion zone, thereby preventing the melting of the frame 1.

연소대에서 발생한 가스(10)는 철 및 슬래그의 비산물과 같이 가스채취구(6)를 통하여 유입되며, 이때 비산물은 용융물 유입방지판(7)에 부착되어 유입이 방지되며 가스(10)는 가스흡입공(8)을 통하여 가스유도로 (2)로 유입된다. 이때 유도로 보호관(3)사이로 유출된 일부 가스(10)는 가스흡입공(8')을 통해 가스유도로(2)로 유입된다.Gas (10) generated in the combustion zone is introduced through the gas collection port 6, such as the iron and slag fly-by, the fly-by is attached to the melt inlet prevention plate (7) to prevent the inflow and gas (10) Is introduced into the gas induction path (2) through the gas suction hole (8). In this case, some of the gas 10 leaked out between the induction furnace protection pipes 3 flows into the gas flow path 2 through the gas suction hole 8 '.

이때 유도로 보호관(3) 및 가스채취구(6)는 사용상태에 따라 교환하여 사용하며, 그 외부분은 계속하여 사용할 수 있다.At this time, the induction furnace protective pipe (3) and the gas collecting port (6) is used according to the use state, the outside can be used continuously.

이와같이 프레임(1)의 용손 및 막힘이 완전 방지되어 종래의 문제점을 완전 해결한 실용적인 고안이다.Thus, the loss and clogging of the frame 1 is completely prevented, a practical design that completely solves the conventional problems.
