카본 제거 방법 및 그 장치{Apparatus and method for removing carbon}Apparatus and method for removing carbon}

본 발명은 카본 제거 방법 및 그 장치에 관한 것이다. 보다 상세하게는, 세라믹 히터를 이용하여 코크스 상승관 내 카본을 제거하는 방법 및 그 장치에 관한 것이다.The present invention relates to a method for removing carbon and a device thereof. More specifically, the present invention relates to a method and apparatus for removing carbon in a coke riser using a ceramic heater.

제철산업에서는 코크스를 산화철을 환원시키는 환원제로 사용하고 있다. 이러한, 코크스는 코크스 오븐(Coke Oven)에서 1100℃이상의 고온에서 석탄을 건류하여 제조한다.In the steel industry, coke is used as a reducing agent to reduce iron oxide. Such coke is produced by distilling coal at a high temperature of 1100 ° C. or higher in a coke oven.

코크스 오븐은 탄화실에 장입되는 석탄을 간접가열하여 코크스를 제조하는 설비이다. 석탄은 장입차에 의해 탄화실에 장입되며, 석탄의 장입과정에서 발생되는 다량의 가스와 분진은 상승관을 통하여 배출된다.The coke oven is a facility for manufacturing coke by indirectly heating coal charged in a carbonization chamber. Coal is charged to the carbonization chamber by a charging car, and a large amount of gas and dust generated during the charging process of the coal is discharged through the riser.

코크스 제조과정에서는 석탄 내 포함된 휘발성 탄소성분이 열분해 되어, 코크스 오븐의 노벽 및 상승관에 카본의 형태로 부착되게 된다. 여기서, 카본은 탄소 약83%와 수소 약2%로 구성되어 있다. 즉, 카본은 탄화수소의 연소현상에서 국소적인 산소부족으로 생성되는 그을음(soot)과 매우 유사한 성질을 가지고 있다.In the coke manufacturing process, volatile carbon components contained in coal are thermally decomposed and attached to the furnace wall and the riser of the coke oven in the form of carbon. Here, carbon is composed of about 83% carbon and about 2% hydrogen. In other words, carbon has properties very similar to soot produced by local oxygen deficiency in hydrocarbon combustion.

본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 여기서, 반복되는 설명, 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능, 및 구성에 대한 상세한 설명은 생략한다. 본 발명의 실시형태는 당 업계에서 평균적인 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위해서 제공되는 것이다. 따라서, 도면에서의 요소들의 형상 및 크기 등은 보다 명확한 설명을 위해 과장될 수 있다.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Here, the repeated description, well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention, and detailed description of the configuration will be omitted. Embodiments of the present invention are provided to more completely describe the present invention to those skilled in the art. Accordingly, the shape and size of elements in the drawings may be exaggerated for clarity.

이하에서는, 본 발명의 실시예에 따른 카본 제거 방법 및 그 장치에 대하여 첨부한 도면을 참고로 하여 상세히 설명한다.Hereinafter, a carbon removal method and an apparatus thereof according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 카본 제거 장치가 적용된 환경을 개략적으로 나타내는 도면이다. 또한, 도 2는 본 발명의 실시예에 따른 카본 제거 장치를 나타내는 구성도이다.1 is a view schematically showing an environment to which a carbon removal device according to an embodiment of the present invention is applied. 2 is a block diagram showing a carbon removal device according to an embodiment of the present invention.

도 1을 참고하면, 코코스 로는 탄화실(10), 탄화실 측면에 배치된 연소실(20) 및 탄화실(10)과 연소실(20)을 지지하는 축열실(21)을 포함한다. 각 연소실(20)은 복수개의 소연소실로 구분되며, 각 소연소실 내로 연료 가스 및 공기가 공급된다.Referring to FIG. 1, the cocos furnace includes acarbonization chamber 10, acombustion chamber 20 disposed on the side of the carbonization chamber, and aheat storage chamber 21 supporting thecarbonization chamber 10 and thecombustion chamber 20. Eachcombustion chamber 20 is divided into a plurality of small combustion chambers, and fuel gas and air are supplied into each small combustion chamber.

탄화실(10)에는 탄장입구(11)를 통해 석탄이 장입되며, 연소실(20)의 각 소연소실에는 열원인 열료 가스와 혼합물을 연소시키는 버너(도시되지 않음)가 장착되어 있으며, 이 버너의 작동에 따라 열이 발생된다. 이와 같이, 소연소실에서 발생된 열이 탄화실(10) 내로 공급되어 석탄을 건류시킴으로써 코크스가 제조된다.In thecarbonization chamber 10, coal is charged through thecoal inlet 11, and each combustion chamber of thecombustion chamber 20 is equipped with a burner (not shown) for burning a mixture of heat material gas as a heat source and a mixture of the burner (not shown). The heat is generated by the operation. Thus, the coke is manufactured by supplying heat generated in the small combustion chamber into thecarbonization chamber 10 and carbonizing the coal.

이처럼, 코크스 제조과정에서는 석탄 내 포함된 휘발성 탄소성분이 열분해 되어, 코코스 로의 노벽 및 상승관(30)에 카본의 형태로 부착되게 된다. 이처럼, 부착된 카본은 건류가 지속될수록 발생 또는 성장하여 내벽에 손상을 가할 뿐만 아니라, 상승관(30)을 통하여 화성공장으로 이송되는 가스의 흐름을 방해되고, 이처럼 가스의 흐름이 방해받는 경우, 작은 폭발이 야기된다.As such, in the process of producing coke, volatile carbon components contained in coal are thermally decomposed to be attached to the furnace wall and theriser 30 of the cocos in the form of carbon. As such, the attached carbon is not only generated or grown as dry matter continues to damage the inner wall, but also hinders the flow of gas transferred to the Hwaseong factory through the risingpipe 30, and thus the flow of gas is hindered. A small explosion is caused.

본 발명의 실시예에 따른, 카본 제거 장치(100)는 탄화실(10) 상부의 상승관(20) 내에 위치하여, 세라믹 히터를 이용하여 부착된 카본을 제거한다. 여기서, 카본 제거 장치(100)는 상승관(20) 내 카본 부착이 많이 발생하는 구역에 위치한다.
According to an embodiment of the present invention, thecarbon removal device 100 is located in theriser 20 above thecarbonization chamber 10 to remove carbon adhered using a ceramic heater. Here, thecarbon removal device 100 is located in a region where a lot of carbon adhesion occurs in theriser 20.

도 2를 참고하면, 카본 제거 장치(100)는 블리더(bleeder)(110), 압전센서(120), 블리더 제어부(130), 산소센서(140), 농도 변화 검출부(150), 히터 제어부(160) 및 발열부(이하 "히터"라고 함)(170)를 포함한다.Referring to FIG. 2, thecarbon removal apparatus 100 may include ableeder 110, apiezoelectric sensor 120, ableeder control unit 130, anoxygen sensor 140, a concentrationchange detection unit 150, and a heater control unit. 160 and a heat generating unit (hereinafter referred to as a "heater") 170.

블리더(110)는 상승관(20) 윗 부분에 위치하며, 개방되어 있는 경우에 카본 제거 작업 중에 발생되는 비산분진을 방출하고, 닫혀있는 경우에 대기의 유입을 차단한다.Thebleeder 110 is positioned above theriser 20 and, when open, emits fugitive dust generated during the carbon removal operation and blocks the inflow of the atmosphere when thebleeder 110 is closed.

압전센서(120)는 블리더(110)의 개폐를 감지한다.Thepiezoelectric sensor 120 detects opening and closing of thebleeder 110.

블리더 제어부(130)는 압전센서(120)의 감지 결과를 이용하여 블리더(110)의 위치를 파악한다. 또한, 블리더 제어부(130)는 탄화실(10) 내에 석탄이 장입하는 경우에 탄화실(10)을 제어하는 특정 제어장치(도시하지 않음)로부터 장입 신호를 전달받아, 장입 신호에 대응하게 블리더(110)를 개방시킨다.Thebleeder controller 130 determines the position of thebleeder 110 by using the detection result of thepiezoelectric sensor 120. In addition, when the coal is charged into thecarbonization chamber 10, thebleeder control unit 130 receives a charging signal from a specific control device (not shown) that controls thecarbonization chamber 10 and responds to the charging signal. Open thereader 110.

산소센서(140)는 상승관(20) 내부의 산소 농도를 감지한다. 여기서, 산소센서(140)는 블리더(110)의 개폐를 압전센서(120)가 감지하지 못할 경우를 대비하여 장착한다.Theoxygen sensor 140 detects the oxygen concentration inside theriser 20. Here, theoxygen sensor 140 is mounted in case thepiezoelectric sensor 120 does not detect the opening and closing of thebleeder 110.

농도 변화 검출부(150)는 산소센서(140)의 감지 결과 즉, 산소 농도를 설정 시간 내지 실시간으로 전달받아, 산소 농도의 변화를 검출한다.The concentrationchange detection unit 150 receives the detection result of theoxygen sensor 140, that is, the oxygen concentration is delivered in a set time or in real time, and detects a change in the oxygen concentration.

일반적으로, 건류시에는 산소 농도가 3%이하이며, 블리더(110)가 개방되는 경우, 상승관(20)으로 대기가 유입되므로 산소 농도가 급격히 증가한다. 이때, 농도 변화 검출부(150)는 산소 농도가 기준치 이상으로 증가되는 것을 검출할 수 있다.In general, oxygen concentration is 3% or less during dry distillation, and when thebleeder 110 is opened, the oxygen concentration rapidly increases because the air flows into theriser 20. At this time, the concentrationchange detection unit 150 may detect that the oxygen concentration is increased above the reference value.

히터 제어부(160)는 농도 변화 검출부(150)에서 검출한 농도 변화가 기준치 예를 들어, 5% 이상인 경우, 히터(170)를 550~600℃로 승온시킨다. 또한, 히터 제어부(160)는 농도 변화가 5% 이하가 되는 경우, 히터(170)의 동작을 종료시킨다.When the concentration change detected by the concentrationchange detection unit 150 is a reference value, for example, 5% or more, theheater controller 160 raises the temperature of theheater 170 to 550 to 600 ° C. In addition, theheater controller 160 terminates the operation of theheater 170 when the change in concentration becomes 5% or less.

히터(170)는 Ni-Cr열선과 세라믹으로 구성되어 있으며, 히터 제어부(160)의 제어에 대응하게 승온하여 카본을 제거한다. 여기서, 카본은 산소 농도가 5%이상, 온도 550℃이상에서 완전연소 즉, 제거된다.
Theheater 170 is composed of a Ni-Cr heating wire and a ceramic, and heats up to correspond to the control of theheater control unit 160 to remove carbon. Here, carbon is completely burned out, that is, removed at an oxygen concentration of 5% or more and a temperature of 550 ° C or more.

다음, 카본 제거 장치가 카본을 제거하는 방법을 도 3을 참조하여 상세하게 설명한다.Next, the method for removing the carbon by the carbon removal apparatus will be described in detail with reference to FIG. 3.

도 3은 본 발명의 실시예에 따른 카본 제거 방법을 나타내는 흐름도이다.3 is a flowchart illustrating a carbon removal method according to an embodiment of the present invention.

먼저, 본 발명의 실시예에 따른 카본 제거 장치(100)는 상승관(30) 내에 위치하며, 이에 한정되지 않는다. 또한, 상승관(30) 내 부착된 카본은 산소 농도가 5%이상, 온도 550℃이상에서 완전연소 즉, 제거된다.First, thecarbon removal device 100 according to the embodiment of the present invention is located in theriser 30, but is not limited thereto. In addition, the carbon adhered in theriser 30 is completely burned, that is, removed at an oxygen concentration of 5% or more and a temperature of 550 ° C or more.

도 3을 참고하면, 카본 제거 장치(100)는 상승관(20) 윗 부분에 위치하는 블리더(110)의 위치를 압전센서(120)를 이용하여 감지한다(S310).Referring to FIG. 3, thecarbon removal apparatus 100 detects the position of thebleeder 110 positioned at the upper portion of theriser 20 using the piezoelectric sensor 120 (S310).

카본 제거 장치(100)는 블리더(110)가 개방되어 있는지를 판단한다(S320).Thecarbon removal apparatus 100 determines whether thebleeder 110 is open (S320).

블리더(110)가가 개방되어 있는 경우, 카본 제거 장치(100)는 산소센서(140)를 이용하여 산소 농도를 감지하여, 산소 농도에 변화가 발생하는지 판단한다(S330).When thebleeder 110 is open, thecarbon removal device 100 detects the oxygen concentration using theoxygen sensor 140 to determine whether a change occurs in the oxygen concentration (S330).

산소 농도에 변화가 발생한 경우, 카본 제거 장치(100)는 히터(170)의 전원을 키고(S340), 550~600℃까지 승온시킨다(S350).When a change occurs in the oxygen concentration, thecarbon removal device 100 turns on the power of the heater 170 (S340) and increases the temperature to 550 to 600 ° C (S350).

카본 제거 장치(100)는 상승관(30) 내 산소 농도가 5%이상, 온도 550℃이상으로 제어하여 카본을 연소시킨다(S360).Thecarbon removal apparatus 100 controls the oxygen concentration in theriser 30 to 5% or more and the temperature of 550 ° C or more to burn carbon (S360).

카본을 모두 연소하여 제거한 경우, 카본 제거 장치(100)는 탄화실(10)을 제어하는 특정 제어장치(도시하지 않음)로부터 탄화실(10) 내에 석탄이 장입 완료되었다는 장입완료 신호를 전달받는다(S370).When all of the carbon is burned and removed, thecarbon removing device 100 receives a charging completion signal indicating that the coal is charged in thecarbonization chamber 10 from a specific control device (not shown) that controls the carbonization chamber 10 ( S370).

다음, 카본 제거 장치(100)는 장입완료 신호에 대응하게 히터(170)의 동작을 종료시키고(S380), 블리더(110)를 닫는다(S390).Next, thecarbon removal device 100 terminates the operation of theheater 170 in response to the charging completion signal (S380), and closes the bleeder 110 (S390).

이로써, 본 발명은 카본을 효율적으로 제거함으로써, 코크스 공정시 발생하는 부생가스를 이송시켜 부생가스의 안정적 생산 및 코크스 조업의 안정성을 확보할 수 있다.
As a result, the present invention can efficiently remove the carbon, thereby transporting the by-product gas generated during the coke process to ensure the stable production of the by-product gas and the stability of the coke operation.
