도 1은 본 발명의 일 실시예에 따른 코크스오븐용 배출가스 처리장치가 도시된 구성도이다.1 is a block diagram showing the exhaust gas treatment apparatus for coke oven according to an embodiment of the present invention.

도 1을 참조하면, 본 발명의 일 실시예에 따른 코크스오븐용 배출가스 처리장치는, 코크스오븐의 배출가스가 통과되도록 유입관(12) 및 배출관(14)이 구비되고, 배출가스 중에 포함되는 조경유를 포집하는 흡수유가 비산되는 스크러버(Scrubber : 10)와, 배출관(14)을 통해 유실되는 조경유를 포집하는 포집부(30)와, 포집부(30)로부터 공급되는 조경유 내에 포함되는 수분을 분리하는 유액분리기(50)를 포함한다.Referring to Figure 1, the coke oven exhaust gas treatment apparatus according to an embodiment of the present invention, the inlet pipe 12 and the discharge pipe 14 is provided so that the discharge gas of the coke oven is passed, the tank included in the exhaust gas Water contained in the scrubber (Scrubber: 10) that the absorption oil for collecting the diesel oil is scattered, the collecting unit 30 for collecting the landscape oil lost through the discharge pipe 14, and the landscape oil supplied from the collecting unit 30 It includes an emulsion separator for separating the.

코크스오븐 배출가스는 스크러버(10)의 하측으로부터 상측으로 이동된 후에 배출관(14)을 통해 스크러버(10) 외부로 배출된다.The coke oven exhaust gas is discharged to the outside of the scrubber 10 through the discharge pipe 14 after being moved from the lower side to the upper side of the scrubber 10.

이때, 스크러버(10) 내부에서는 상부로부터 하측으로 흡수유가 비산되므로 배출가스 중에 포함되는 조경유를 포집하여 하측으로 떨어지게 된다.At this time, in the scrubber 10, the absorbent oil is scattered from the upper side to the lower side, so that the landscape oil contained in the exhaust gas is collected and falls to the lower side.

이때, 코크스오븐 배출가스는 고압으로 유입관(12)을 통해 스크러버(10) 내부로 공급되므로 배출가스의 압력에 의해 스크러버(10) 내부에 비산되는 흡수유가 배출관(14) 측으로 유실될 수 있다.At this time, the coke oven exhaust gas is supplied into the scrubber 10 through the inlet pipe 12 at a high pressure, so that the absorbed oil scattered inside the scrubber 10 by the pressure of the exhaust gas may be lost to the discharge pipe 14 side.

포집부(30)는 배출관(14)의 일부분이 'U' 모양으로 돌출되어 이루어지는 공간부(32)와, 공간부(32)로부터 유액분리기(50)로 분기되는 분기관(34)을 포함한다.The collecting part 30 includes a space part 32 in which a part of the discharge pipe 14 protrudes in a 'U' shape, and a branch pipe 34 branched from the space part 32 to the oil separator 50. .

흡수유는 타르계의 오일이므로 흡수유는 공간부(32)의 하부에 담유되고, 배출가스는 배출관(14)을 따라 다음 공정으로 이동된다.Since the absorbent oil is a tar-based oil, the absorbent oil is immersed in the lower portion of the space 32, and the exhaust gas is moved to the next process along the discharge pipe 14.

공간부(32)에 담유되는 흡수유는 분기관(34)을 따라 유액분리기(50)에 공급되고, 유액분리에서 흡수유에 포함되는 수분이 제거된 후에 스크러버(10) 측으로 재공급된다.The absorbent oil contained in the space 32 is supplied to the oil separator 50 along the branch pipe 34, and is re-supplied to the scrubber 10 after the water contained in the absorbent oil is removed in the oil separation.

따라서 배출관(14)을 따라 유실되는 흡수유를 포집하여 재활용할 수 있으므로 코크스오븐 배출가스를 정화하는데 소요되는 비용을 줄일 수 있게 된다.Therefore, the absorbed oil lost along the discharge pipe 14 can be collected and recycled, thereby reducing the cost of purifying the coke oven exhaust gas.

또한, 본 실시예는, 스크러버(10)로부터 배출되는 흡수유를 가열시키는 가열부(70)와, 가열부(70)에 의해 설정온도로 가열되어 공급되는 흡수유가 통과되고, 스팀과 흡수유를 비산시켜 흡수유 중에 포함되는 조경유를 포집하는 디설버(Desorber : 80)와, 디설버(80)로부터 배출되는 조경유로부터 수분을 분리하여 조경유 및 수분을 배출하는 수분분리기(86)를 더 포함한다.In this embodiment, the heating unit 70 for heating the absorbent oil discharged from the scrubber 10 and the absorbing oil heated and supplied to the set temperature by the heating unit 70 pass through the steam unit and the absorbent oil. Dissolver (80) for scattering the landscaping oil contained in the absorbent by scattering, and a water separator (86) for separating the landscape oil and water by separating the water from the landscape oil discharged from the dissolver (80). Include.

조경유를 포집하여 스크러버(10)로부터 배출되는 흡수유는 가열부(70)를 통과하면서 설정온도가 가열된 후에 디설버(80)에 공급되고, 디설버(80)의 하부로부터 스팀이 분사되므로 상승되는 스팀과 흡수유가 접촉되면서 조경유가 흡수유로부터 분리된다.Absorbed oil collected from the scrubber 10 by collecting the landscape oil is supplied to the dissolver 80 after the set temperature is heated while passing through the heating unit 70, and steam is injected from the lower portion of the dissolver 80. As the rising steam comes into contact with the absorbent oil, the landscape oil separates from the absorbent oil.

디설버(80) 내부에서 조경유와 분리되는 흡수유는 순환관(82)을 따라 배출되어 냉각기(84)를 통과하면서 냉각된 후에 수분분리기(86)를 통과하면서 수분이 제거되어 순도가 높은 흡수유로 변환되고, 순환관(82)을 따라 디설버(80) 내부로 재공급된다.Absorbent oil separated from the landscape oil in the dissolver 80 is discharged along the circulation pipe 82 and cooled while passing through the cooler 84, and then the water is removed while passing through the water separator 86 to absorb high purity. The flow path is converted and resupplied into the dissolver 80 along the circulation pipe 82.

디설버(80) 내부에서 고온의 스팀에 의해 흡수유로부터 분리되는 조경유는 스팀과 함께 배출되고, 수분분리기(86)를 통과하면서 조경유와 수분이 분리되어 각각 별도의 유로로 배출된다.The landscape oil separated from the absorbent oil by the high temperature steam in the dissolver 80 is discharged together with the steam, and the landscape oil and water are separated while passing through the water separator 86 and discharged into separate flow paths, respectively.

가열부(70)는, 스크러버(10)로부터 흡수유가 배출되는 제1배유관(16)과 디설버(80)로부터 흡수유가 배출되는 제2배유관(88)이 서로 교차되는 열교환기(72)와, 열교환기(72)를 통과한 흡수유를 가열하여 디설버(80)로 공급하는 히터(74)를 포함한다.The heating unit 70 includes a heat exchanger 72 in which a first oil pipe 16 through which absorbed oil is discharged from the scrubber 10 and a second oil pipe 88 through which absorbed oil is discharged from the dissolver 80 cross each other.

디설버(80) 내부의 온도가 스크러버(10) 내부의 온도와 비교하여 높기 때문에 열교환기(72) 내부에서 스크러버(10)로부터 배출되는 흡수유와 디설버(80)로부터 배출되는 흡수유가 교차되도록 하여 폐열을 활용한 가열작동을 행할 수 있게 된다.Since the temperature inside the dissolver 80 is higher than the temperature inside the scrubber 10, the absorbed oil discharged from the scrubber 10 and the absorbed oil discharged from the dissolver 80 cross each other in the heat exchanger 72. Thus, the heating operation utilizing the waste heat can be performed.

스크러버(10)와 열교환기(72) 사이에는 오일탱크(76)가 설치되고, 유액분리기(50)에서 분리되는 흡수유는 오일탱크(76)에 공급된다.An oil tank 76 is installed between the scrubber 10 and the heat exchanger 72, and the absorbent oil separated from the oil separator 50 is supplied to the oil tank 76.

따라서 배출관(14)을 따라 유실되는 흡수유는 공간부(32)와 분기관(34)을 통해 오일탱크(76)로 모아진 후에 열교환기(72), 히터(74) 및 디설버(80)를 지나 다시 스크러버(10) 내부로 재공급된다.

디설버(80)의 하부로부터 공급되는 스팀은 흡수유에 포함되는 조경유를 포집하여 수분분리기(86)를 지나 배출되고, 디설버(80)에서 순환관(82)을 따라 순환되는 흡수유는 냉각기(84)를 통과하면서 냉각된 후에 수분분리기(86)를 지나 다시 디설버(80)로 재공급된다.Steam supplied from the lower portion of the dissolver 80 captures the landscape oil contained in the absorbent oil and is discharged through the water separator 86, and the absorbent oil circulated along the circulation pipe 82 in the dissolver 80 is a cooler. After cooling through 84, it is fed back to the dissolver 80 through the water separator 86.

디설버(80)로 공급되는 순도 높은 흡수유는 스크러버(10)로부터 공급되는 흡수유를 포집하여 디설버(80) 하부로 배출되고, 열교환기(72)를 지나 다시 스크러버(10)로 공급된다.The high-purity absorbent oil supplied to the dissolver 80 collects the absorbed oil supplied from the scrubber 10, is discharged to the lower portion of the dissolver 80, and passes through the heat exchanger 72 to the scrubber 10 again. .

이로써, 코크스오븐 배출가스 중에 포함되는 이물질을 제거할 때에 배출관을 따라 유실되는 흡수유를 회수할 수 있는 코크스오븐용 배출가스 처리장치를 제공할 수 있게 된다.
