본 고안은 로내에 설치형의 흡열형 가스발생장치에 관한 것이다.The present invention relates to an endothermic gas generator of a type installed in a furnace.
종래에 흡열형 가스를 로내의 분위기 가스로서 사용하는 경우에는 별도로 설치하게 되는 변성로내에 니켈계열등의 촉매를 충전한 가스변성레톨르트를 배치하고, 메탄, 부탄, 프로판등의 탄화수소가스와 일정한 비율의 공기와의 원료가스를 상기한 레톨르트내에 공급하여 일정한 온도로 간직한 촉매에 상기한 원료가스를 접촉하게 함에 따라 변성가스로 하였으며, 이것을 냉각장치에 냉각한 다음 열처리로에 공급하고 있다.Conventionally, when endothermic gas is used as an atmosphere gas in a furnace, a gas-modified retort filled with a catalyst such as nickel series is disposed in a modified furnace that is separately installed, and has a constant ratio with hydrocarbon gas such as methane, butane and propane. The feed gas with air was supplied into the retort described above, and the modified feed gas was brought into contact with the catalyst kept at a constant temperature to form a modified gas, which was cooled in a cooling apparatus and then supplied to a heat treatment furnace.
이와 같이 흡열형 가스를 변성하여 로내 분위기로서 사용하기 위하여서는 변성로뿐 아니라 냉각장치가 필요하게 되므로 비싸지게 된다고 하는 결점을 지니고 있다.As described above, in order to modify the endothermic gas and use it as an in-furnace atmosphere, there is a drawback that it becomes expensive because not only the denatured furnace but also the cooling device is required.
본 고안은 흡열형 가스를 열처리로에서 사용함에 있어서는 상기한 냉각장치가 불필요하다는 사실 및 로내의 고온분위기를 가스레톨로트의 열원으로서 사용할 수 없는 지를 여러가지로 검토한 결과 성취한 것으로 흡열형 가스발생장치를 입상내화물층(粒狀耐火物層)사이에 촉매가 충전되고, 일단에 원료가스공급구를 타단에 변성가스출구를 지닌 변성레톨르트와, 이 레톨르트를 보열부재로 포위함과 동시에 변성레톨르트와 보열부재와의 사이에 변성레톨르트를 포위할 수 있게 전기발열체를 근접 배치한 구성으로 로에 직접장치할 수 있도록 한 것이다. 즉 로내 분위기온도 및 전기발열체에 의하여 촉매를 항상 일정한 온도로 유지하여 원료가스를 일정한 조성의 변성가스로하고, 이 변성가스를 직접 로내에 분출하도록 하여 종래의 것에 비하여 에너지절약을 꾀함과 동시에 냉각장치를 불필요로한 로내에 설치형의 흡열형 가스발생장치를 제공하려하는 것이다. 다음에 본 고안을 한 실시예로서의 첨부도면에 따라서 설명한다.The present invention has been accomplished by examining the fact that the above-mentioned cooling device is unnecessary when the endothermic gas is used in the heat treatment furnace and whether or not the high temperature atmosphere in the furnace can be used as the heat source of the gas relot lot. The catalyst is filled between the granular refractory layers, the modified retort having a raw gas supply port at one end and a modified gas outlet at the other end, and the retort is surrounded by a heat retaining member and at the same time the modified retort is And a heating element disposed close to each other so as to surround the modified retort with the heat retaining member. In other words, the catalyst is always maintained at a constant temperature by the furnace atmosphere temperature and the electric heating element, so that the raw material gas is a modified gas having a constant composition, and the modified gas is directly discharged into the furnace to save energy and to provide a cooling device. It is an object of the present invention to provide an endothermic type gas generating device installed in a furnace. Next, the present invention will be described according to the accompanying drawings as an embodiment.
제1도는 본 고안에 관한 흡열형 가스발생장치를 설비한 열처리로(T)의 단면도로서, 로내에는 라디안트튜브(1)가 천정벽(2)에는 분위기 순환선풍기(3)와 흡열형 가스발생장치(이하 가스발생장치라고 한다)(5)가 종으로 설치되어, 로내에 장착하여 넣은 지지구조(4)상의 처리재(W)는 흡열형 가스를 함유하는 분위기속에서 가열되어 탄소첨가 어니일링등의 열처리를 실시하게 되는 것이다.1 is a cross-sectional view of a heat treatment furnace (T) equipped with an endothermic gas generator according to the present invention, in which a radiant tube (1) is provided in the furnace, and an atmospheric circulation fan (3) and an endothermic gas are provided in the ceiling wall (2). A generator (hereinafter referred to as a gas generator) 5 is provided longitudinally, and the treatment material W on the support structure 4 mounted in the furnace is heated in an atmosphere containing an endothermic gas and carbon-added. It is to perform heat treatment such as e-ling.
상기한 가스발생장치(5)는 제2도, 제3도에서 보는 바와 같이 단열재(7)를 안에 바른 내열합금제 또는 내열 세라믹제의 보열부재(6)와, 이 보열부재(6)에 일정한 간극을 개재하여 관통해서 설치된 내열합금제 또는 내열세라믹제의 변성레톨르트(8)등으로 이루어져 있다. 그리고, 상기한 변성레톨르트(8)의 일단에는 변성가스토출구(9)를 타단에는 원료가스공급구(11)를 지닌 내화재(10)가 마련되어 있으며, 내부에는 알갱이 모양의 니켈계, 백금계, 루테늄계, 로듐계등의 촉매층(12)이 마련되어 있다.The gas generator 5 has a heat-resistant alloy 6 made of heat-resistant alloy or heat-resistant ceramic with a heat insulating material 7 therein as shown in FIGS. 2 and 3, and fixed to the heat-retaining member 6. It consists of a modified alloy 8 made of a heat-resistant alloy or a heat-resistant ceramic provided through the gap. Then, one end of the modified retort (8) is provided with a refractory material (10) having a modified gaseous outlet (9) at the other end and a source gas supply (11), inside the granular nickel-based, platinum-based, A catalyst layer 12 such as ruthenium-based or rhodium-based is provided.
더우기(13)는 촉매지지용 입상내화물, (14)는 지지대, (15)는 원료가스예열용 입상내화제이다. 또 상기한 보열부재(6)와 변성레톨르트(8)와의 간극에는 전기발열체(16)와 열전대(17)가 설치되어 있다. 한편, 전기발열체(16)는 변성레톨르트(8)를 포위할 수 있게 근접 배치되어 있다.Moreover, 13 is a granular refractory material for catalyst support, 14 is a support stand, and 15 is a granular refractory agent for raw material gas preheating. In addition, an electric heating element 16 and a thermocouple 17 are provided in the gap between the heat retaining member 6 and the modified retort 8. On the other hand, the electric heating elements 16 are arranged close to each other so as to surround the modified retort 8.
그리고, 상기한 가스발생장치(5)는 천정벽(2)에 장치되어 변성레톨르트(8)의 로 외부분에 위치하는 원료가스 공급구(11)에서 탄화수소가스 (프로판, 메탄, 부탄등)과 공기와를 일정한 비율로 되도록 혼합기(18)로 혼합한 원료가스를 공급하고 촉매층(12)으로 흡열형 가스로 변성되어서 토출구(9)에서 로내에 부출하여 로내분위기 가스로 된다.In addition, the gas generator 5 is installed on the ceiling wall 2 and the hydrocarbon gas (propane, methane, butane, etc.) at the source gas supply port 11 located outside the furnace of the modified retort 8. The raw material gas mixed with the air and the air in a constant ratio is supplied to the mixer 18, and is converted into an endothermic gas into the catalyst layer 12, and is discharged into the furnace from the discharge port 9 to become an atmosphere in the furnace gas.
(19),(20)은 유량개, (21)은 탄화수소가스 압력조정기이다. 상기한 촉매층(12)에서 원료가스를 흡열형 가스로 변성함에 필요한 열량은 주로 전기발열체(16)에 의하는 것이나, 로내 온도가 고온일때면 보열부재(6)를 개재하여 이용한다. 또, 레톨르트(8)내의 온도는 상기한 열전대(17)로 부터의 신호를 온도조절계(22)에 의하여 설정치와 비교하여 개폐기(23)를 개폐하여 전기발열체(16)의 발열량을 제어하여 상기한 촉매층(12)의 온도를 원료가스의 반응을 충분히 함에 충분한 800-1050℃로 유지할 수 있도록 되어 있다.(19) and (20) are flow rate openings, and (21) is a hydrocarbon gas pressure regulator. The amount of heat required for modifying the source gas into the endothermic gas in the catalyst layer 12 is mainly based on the electric heating element 16, but is used via the heat retaining member 6 when the furnace temperature is high. The temperature in the retort 8 compares the signal from the thermocouple 17 with the set value by the temperature controller 22 to open and close the switch 23 to control the amount of heat generated by the electric heating element 16. The temperature of one catalyst layer 12 can be maintained at 800-1050 ° C. sufficient to sufficiently react the source gas.
이상의 설명에서 명백한 바와같이 본 고안에 관한 흡열형 가스발생장치는 로에 설치하여 사용하는 것이므로 종래에 있어서는 냉각장치로 일단 냉각한 흡열형 가스를 온도상승을 하고 있는 승온공정이 불필요하다.As apparent from the above description, since the endothermic gas generator according to the present invention is installed in a furnace and used, in the related art, a temperature raising step of raising the temperature of the endothermic gas once cooled by the cooling apparatus is unnecessary.
따라서 종래에 변성로가열에 약 800kcal/㎥, 재 가열에 약 250kcal/㎥로 충분하므로 대폭적인 에너지절약을 도모할수 있다.Therefore, about 800 kcal / m 3 for heating the modified furnace and 250 kcal / m 3 for reheating are sufficient in the related art, and thus, a significant energy saving can be achieved.
또, 종래에 있어서는 열처리로의 이외에도 변성로를 설치하지 않으면 안되었으나 본 고안에 관한 흡열형 가스발생장치는 직접 로에 장치하는 것이기 때문에 변성로의 설치 스페이스가 불필요하게 되며, 스페이스의 효과적인 이용도 가능하다할 것이다.In addition, in the related art, in addition to the heat treatment furnace, a denatured furnace had to be installed, but the endothermic gas generator according to the present invention is installed directly in the furnace, so that a space for installing the denatured furnace is unnecessary, and the space can be effectively used. something to do.
나아가서 레톨르트내의 촉매는 레톨르트외주에 설치한 전기발열체에의하여 가열되는 것이므로, 로 온도가 강하하여도 일정한 온도로 유지하고 항상 일정한 성분의 흡열형 가스를 얻을 수 있다.Furthermore, since the catalyst in the retort is heated by an electric heating element provided on the periphery of the retort, it is possible to maintain the constant temperature even when the furnace temperature drops and always obtain an endothermic gas having a constant component.
특히 촉매를 입상내화물층 사이에 위치되어 있으므로, 원료가스는 예열되는 한편, 촉매층의 극부적(특히 하부)인 과열 혹은 온도저하없이 또는 변성레톨르트 본체를 보열부재에서 포위됨과 동시에 전기발열체를 변성레톨르트 주위에 배치되어있으므로 로내의 온도가 일시적으로 강하(배치식 로의 재료장입시)하여도 촉매층의 온도가 일정하게 유지되고, 특히 종으로 놓아두기 때문에 원료가스가 촉매층내에 완전히, 한편 균일하게 관류하게 되며, 성분의 안정한 흡열형 가스를 로내에 직접 공급할 수 있다.In particular, since the catalyst is located between the granular refractory layers, the raw material gas is preheated, while the overheating or temperature decrease of the catalyst layer is overheated or the modified retort body is surrounded by the heat retaining member and the heating element is modified. Since it is disposed around the furnace, the temperature of the catalyst bed is kept constant even when the temperature in the furnace drops temporarily (when the material is loaded into the batch type furnace), and in particular, it is placed as a bell so that the source gas flows completely and uniformly in the catalyst bed. The stable endothermic gas of the component can be directly supplied into the furnace.
