도 1을 참조하면, 일반적으로 석탄을 원료로 하여 코크스 오븐에서 코크스를 생산하게 될 때 코크스 오븐에서 건류가 완료된 적열코크스(C)는 압출기(10)에 의해 압출되어 이송카(20)로 옮겨지게 된다.Referring to FIG. 1, in general, when coke is produced in a coke oven using coal as a raw material, red coke C dried in the coke oven is extruded by an extruder 10 to be transferred to a transfer car 20. do.

적열코크스(C)의 압출 시 발생되는 미분의 코크스 등 각종 분진 및 가스는 집진설비에 의해 흡입되어 제거된다. 이하 각종 분진 및 가스를 약칭하여 ‘분진’이라 칭한다. Various dusts and gases such as fine coke generated during extrusion of the red coke C are sucked and removed by a dust collecting facility. Hereinafter, various dusts and gases are abbreviated as "dust".

이러한 집진설비는 분진 발생지역에 인접하게 배치되어 적열코크스(C)의 압출 시 발생되는 분진을 흡입하는 집진후드(31)와, 집진후드(31)와 연통되게 설치되는 집진덕트(100)와, 집진덕트(100)를 통해 이송되는 분진을 필터링하여 제거하는 백(Bag)필터가 내장되는 백(Bag)실(32)과, 집진후드(31)와 집진덕트(100)에 흡입력을 제공하는 집진메인팬(33) 등으로 구성된다. Such a dust collecting facility is disposed adjacent to the dust generating region and a dust collecting hood 31 for sucking dust generated during the extrusion of the red coke (C), and a dust collecting duct 100 installed in communication with the dust collecting hood 31; Bag chamber 32 in which a bag filter for filtering and removing dust transported through the dust collecting duct 100 is embedded, and a dust collecting material providing suction power to the dust collecting hood 31 and the dust collecting duct 100. And a main fan 33 or the like.

도 1 내지 도 4를 참조하면, 본 발명의 일 실시예에 따른 집진장치(1)는 집진덕트(100)와 냉각장치(200)를 포함하여 이루어진다.1 to 4, the dust collecting apparatus 1 according to the exemplary embodiment of the present invention includes a dust collecting duct 100 and a cooling apparatus 200.

집진덕트(100)는 일측이 집진후드(31)와 연통되고 타측이 백실(32)과 연통된다. 구체적으로, 집진덕트(100)는 적열코크스(C)의 압출 시 발생되는 분진을 흡입하기 위해 분진 발생지역에 인접하게 배치되는 집진후드(31)와 연통되어 흡입된 분진을 백실(32)로 안내한다. 백실(32)에는 백필터가 내장되어 있으므로 인입되는 분진을 필터링하게 된다. The dust collecting duct 100 has one side communicating with the dust collecting hood 31 and the other side communicating with the bag chamber 32. Specifically, the dust collecting duct 100 is in communication with the dust collecting hood 31 disposed adjacent to the dust generating area to suck the dust generated during the extrusion of the red coke (C) guides the sucked dust to the bag chamber (32). do. The bag chamber 32 has a built-in bag filter to filter the incoming dust.

집진덕트(100)는 전환부(110)와 몸체부(120)를 포함하여 이루어진다. 집진덕트(100)는 전환부(110)를 통해 유로의 방향이 전환되며, 몸체부(120)는 전환부(110)의 하측에 연통되어 전환부(110)를 통해 방향이 전환된 분진을 백실(32)로 안내한다. The dust collecting duct 100 includes a switching unit 110 and a body 120. The dust collecting duct 100 is switched in the direction of the flow path through the switching unit 110, the body portion 120 is communicated to the lower side of the switching unit 110, the dust through which the direction is switched through the switching unit 110 Guide to (32).

집진덕트(100)는 전환부(110)의 하측에 배치되는 몸체부(120)를 기준으로 이전(以前)보다 이후(以後)의 내부 단면적이 넓어진다. 따라서, 몸체부(120)를 통과하는 분진의 유속은 몸체부(120)의 이전보다 더 느려지게 된다. The dust collecting duct 100 has a wider internal cross-sectional area than the previous one with respect to the body part 120 disposed below the switching unit 110. Therefore, the flow rate of the dust passing through the body portion 120 is slower than before the body portion 120.

냉각장치(200)는 집진덕트(100)에 설치되어 집진덕트(100)를 통과하는 분진을 냉각시켜 백실(32)에 인입되는 분진의 온도를 낮춘다. 냉각효율을 향상시키기 위해서는 냉각장치(200)를 흐르는 냉각수와 집진덕트(100)를 통과하는 분진의 접촉 면적을 증가시켜야 하므로, 냉각장치(200)는 분진의 유속이 다른 곳보다 상대적으 로 느린 몸체부(120)에 설치된다. 물론, 이는 냉각효율을 극대화하기 위한 수단의 하나이므로, 냉각장치(200)가 몸체부(120)가 아닌 집진덕트(100)의 어느 부분에라도 설치될 수 있음은 물론이다. The cooling apparatus 200 is installed in the dust collecting duct 100 to cool the dust passing through the dust collecting duct 100 to lower the temperature of the dust introduced into the bag chamber 32. In order to improve the cooling efficiency, the contact area between the coolant flowing through the cooling device 200 and the dust passing through the dust collecting duct 100 must be increased, and thus the cooling device 200 has a relatively slow body velocity of dust. It is installed in the unit 120. Of course, since this is one of means for maximizing the cooling efficiency, the cooling device 200 may be installed in any part of the dust collecting duct 100, not the body portion 120.

냉각장치(200)는 냉각수 유입부(210), 냉각수 배출부(220), 연결부(230)를 포함하여 이루어진다. The cooling device 200 includes a coolant inlet 210, a coolant outlet 220, and a connection 230.

냉각수 유입부(210)는 일측에서 공급관(211)과 연통되고, 타측에서 연결부(230)와 연통된다. 공급관(211)은 외부의 냉각수 공급원과 연결되어 이로부터 공급받은 냉각수를 냉각수 유입부(210)에 제공하며, 냉각수 유입부(210)는 제공받은 냉각수를 연결부(230)에 전달한다. Cooling water inlet 210 is in communication with the supply pipe 211 on one side, it is in communication with the connecting portion 230 on the other side. The supply pipe 211 is connected to an external coolant supply source to provide the coolant supplied from the coolant inlet 210 to the coolant inlet 210, and the coolant inlet 210 delivers the provided coolant to the connection unit 230.

냉각수 유입부(210)는 집진덕트(100)의 외부에 배치될 수 있다. 이로써, 공급관(211)과 냉각수 유입부(210)의 연결을 원활히 이룰 수 있게 된다. 이와 동일하게 냉각수 배출부(220) 또한 집진덕트(100)의 외부에 배치될 수 있다.Cooling water inlet 210 may be disposed outside the dust collecting duct (100). As a result, the supply pipe 211 and the coolant inlet 210 may be smoothly connected. In the same manner, the coolant discharge part 220 may also be disposed outside the dust collecting duct 100.

냉각수 배출부(220)는 일측에서 연결부(230)와 연통되고, 타측에서 배출관(221)과 연통된다. 이로써, 연결부(230)에서 집진덕트(100)를 통과하는 분진과 열교환되어 유입 시보다 뜨거워진 냉각수는 냉각수 배출부(220)와 배출관(221)을 통해 외부로 배출된다. The coolant discharge part 220 is in communication with the connection part 230 at one side, and in communication with the discharge pipe 221 at the other side. As a result, the heat exchanged with the dust passing through the dust collecting duct 100 in the connecting portion 230, the cooling water that is hotter than the inlet is discharged to the outside through the cooling water discharge unit 220 and the discharge pipe 221.

연결부(230)는 일측이 냉각수 유입부(210)와 연통되고, 타측이 냉각수 배출부(220)와 연통되어 냉각수가 집진덕트(100)를 통과하는 분진과 열교환되도록 냉각수의 유동을 안내한다. The connection part 230 guides the flow of the cooling water so that one side is in communication with the cooling water inlet 210 and the other side is in communication with the cooling water discharge part 220 so that the cooling water exchanges with the dust passing through the dust collecting duct 100.

연결부(230)는 수평 방향으로 일정 간격으로 복수개가 배열되며, 내부를 흐 르는 냉각수의 유동 마찰을 줄이기 위해 내측 단면이 원형을 이루는 원기둥 형상으로 형성된다. The connecting portion 230 is arranged in a plurality at regular intervals in the horizontal direction, in order to reduce the flow friction of the cooling water flowing inside is formed in a cylindrical shape of the inner cross-section is circular.

한편, 도 5를 참조하면, 본 발명의 다른 실시예에 따른 냉각장치(200)는 연결부(230)가 외측 단면이 사각형을 이루는 기둥 형상으로 형성되며, 수평 방향으로 일정 간격으로 복수개가 배열된다. 이러한 연결부(230)는 일종의 충돌판 역할을 하여 집진덕트(100)의 내부를 통과하는 분진과 충돌을 유발하여 분진의 유속을 낮춘다. 연결부(230)에 의해 충돌된 분진은 속도가 저감되면서 자유 낙하하게 되며, 집진덕트(100)의 하부에 설치되는 분진포집부(미도시)에 의해 제거된다. 이로써, 연결부(230)의 외측면에 충돌할 수 있는 정도로 입자가 상대적으로 큰 분진은 백실(32)까지 안내하지 않고도 제거할 수 있게 된다. On the other hand, referring to Figure 5, the cooling device 200 according to another embodiment of the present invention, the connection portion 230 is formed in a columnar shape of the outer cross-section is a square, a plurality are arranged at a predetermined interval in the horizontal direction. The connection portion 230 serves as a kind of collision plate to cause a collision with the dust passing through the interior of the dust collecting duct 100 to lower the flow rate of the dust. The dust impinged by the connecting portion 230 is free fall while the speed is reduced, is removed by a dust collector (not shown) installed in the lower portion of the dust collecting duct (100). As a result, dust having a relatively large particle size that may collide with the outer surface of the connecting portion 230 may be removed without guiding the bag chamber 32.

이하, 도 1 내지 도 5를 참조하여 본 발명의 실시예에 따른 집진장치의 작동원리를 설명하기로 한다.Hereinafter, the operation principle of the dust collecting apparatus according to the embodiment of the present invention will be described with reference to FIGS. 1 to 5.

적열코크스(C)의 압출 시 발생되는 분진은 집진후드(31)에 의해 흡입되어 집진덕트(100)를 통해 백실(32)로 안내되며, 단면적이 이전보다 상대적으로 더 넓은 집진덕트(100)의 일측, 본 실시예에서는 몸체부(120),에 설치되는 냉각장치(200)에 의해 냉각된다. Dust generated during the extrusion of the red coke C is sucked by the dust collecting hood 31 and guided to the bag chamber 32 through the dust collecting duct 100, and the cross-section of the dust collecting duct 100 having a relatively larger cross section than before. One side, in this embodiment is cooled by the cooling unit 200 is installed in the body portion 120 ,.

분진의 유동 통로인 집진덕트(100)의 내부에는 냉각수 유입부(210) 및 냉각수 배출부(220)와 연통되는 연결부(230)가 수평 방향으로 복수개가 배열되어 있어 고온의 분진은 연결부(230)와의 접촉에 의해 냉각된다. 즉, 냉각수 유입부(210)에 서 냉각수 배출부(220)로 흐르는 냉각수는 연결부(230)에서 고온의 분진과 접촉하여 분진의 열을 회수하게 되므로 분진은 연결부(230)를 통과하면서 그 온도가 낮아지게 된다. Inside the dust collecting duct 100, which is a flow path of dust, a plurality of connection parts 230 communicating with the cooling water inlet 210 and the cooling water discharge part 220 are arranged in a horizontal direction, so that high-temperature dust is connected to the connection part 230. Cooled by contact with That is, since the coolant flowing from the coolant inlet 210 to the coolant outlet 220 recovers the heat of the dust by contacting the high temperature dust at the connector 230, the dust passes through the connector 230 and the temperature thereof is increased. Will be lowered.

한편, 열교환된 냉각수는 냉각수 배출부(220)와 배출관(221)을 통해 외부로 계속적으로 배출되고, 이와 동시에 새로운 냉각수가 공급관(211)과 냉각수 유입부(210)를 통해 연결부(230)에 계속적으로 공급되므로, 집진덕트(100)를 통과하는 분진의 온도를 계속적으로 낮출 수 있게 된다. Meanwhile, the heat exchanged coolant is continuously discharged to the outside through the coolant discharge unit 220 and the discharge pipe 221, and at the same time, the new coolant is continuously connected to the connection unit 230 through the supply pipe 211 and the coolant inlet unit 210. Since it is supplied to, it is possible to continuously lower the temperature of the dust passing through the dust collecting duct (100).
