본 고안은 페타이어나 합성수지, FRP 등의 산업폐기물을원료로 하는 연소장치에 있어서 그 연소의 효과를 가일층 높일 수 있도록 한 건류식 개스화기의 2차공기공급장치에 관한 것이다. 종래에도 산업폐기물을 연소시키기 위한 여러 종류가 있었는 바, 그 일예로 표시한 제1도의 연소장치는 1차공기공급팬(5)에 의하여 약간의 공기가 연소실(1)의 하부에 형성된 공기공급노즐(3)을 통하여 공급되도록 하고, 공기공급노즐(3)의 상부에는 자갈과 모래로서 연소실 저면(2)을 이루게 하여 연소실(1)의 개폐문(1')으로 장입되는 산업폐기물의 연료를 점화구(4)의 열원에 의하여 서서히 연소되도록 한다음 연소실(1)에서 발생되는 열원을 연소관(6)을 통과할 때 연소관(6)의 점화버너(7)와 2차공기공급팬(5')에 의하여 완전연소시키므로서 연소관(6)의 선단에서 화염이 발생되도록 한 것이다.The present invention relates to a secondary air supply device of a dry gas type gasifier that can further enhance the effect of combustion in a combustion device using industrial waste materials such as tires, synthetic resins, and FRP. Conventionally, there have been various types for burning industrial waste. In the combustion apparatus shown in FIG. 1, an air supply nozzle in which some air is formed in the lower part of the combustion chamber 1 by the primary air supply fan 5 is shown. (3) and the fuel supply of the industrial waste charged into the opening and closing door (1 ') of the combustion chamber 1 to form the bottom of the combustion chamber (2) as gravel and sand on the upper portion of the air supply nozzle (3). 4) by the ignition burner 7 and the secondary air supply fan (5 ') of the combustion tube (6) when the heat source generated in the combustion chamber (1) passes through the combustion tube (6). By completely burning, the flame is generated at the tip of the combustion tube (6).
그런데 상기의 장치에 의하면 점화버너(7)로서 연소관(6)을 미리 약 600℃정도로 가열시켜서 사용하는데 2차공기공급팬(5')으로 2차공기를 연소관(6)에 공급할 때 2차공기에 의하여 연소관(6)의 내부온도가 점차적으로 낮아지게 되어 연소실(1)에서 발생되는 열원을 완전연소시키지 못하였을 뿐만 아니라 2차공기공급시에 2차공기가 연소실(1)측으로 역류되는 사례가 가끔 발생하여 연소실(1)의 열원을 소화시키게 되는 등의 문제점이 있었다.However, according to the above apparatus, the combustion tube 6 is used as the ignition burner 7 beforehand by heating to about 600 ° C. The secondary air is supplied to the combustion tube 6 by the secondary air supply fan 5 '. As a result, the internal temperature of the combustion tube 6 is gradually lowered, thereby not only completely burning the heat source generated in the combustion chamber 1 but also causing the secondary air to flow back to the combustion chamber 1 side when supplying the secondary air. Occasionally there was a problem such as to extinguish the heat source of the combustion chamber (1).
따라서 본 고안은 상기와 같은 종래의 문제점을 해소하기 위하여 2차공기공급시에 연소관(6)의 내부온도가 점차적으로 낮아지게 되는 것과 2차공기가 역류되지 못하도록 하므로서 연소관(6)의 선단에서 발생되는 화염이 항상 정상연소를 유지케하여 산업폐기물을 적합한 연료로 사용할 수 있게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention is generated at the tip of the combustion tube (6) by gradually reducing the internal temperature of the combustion tube (6) at the time of supplying secondary air and preventing the secondary air from flowing back in order to solve the conventional problems as described above. The flame is to always maintain the normal combustion to enable the use of industrial waste as a suitable fuel as described in detail by the accompanying drawings as follows.
연소관(6)을 내열성과 보온성이 양호한 내체(6a)와 외체(6b)로 구분형성하여 그 사이의 간격에 코일형으로 된 2차공기유도익(8)을 위치케 하고 2차공기공급팬(5')을 외체(6a)의 선단에 2차공기가 2차공기유도익(8)의 선단부에서 후단부를 통과하여 배출방향이 열원 진행방향으로 형성된 2차공기 배출관(9)으로 배출되도록 하여서 된 것으로 점화버너(7)의 선단부는 2차공기배출관(9)의 전방에 위치되도록 하였다.The combustion tube 6 is divided into an inner body 6a and an outer body 6b having good heat resistance and warmth, and the secondary air induction vanes 8, which are coiled, are positioned at intervals therebetween, and the secondary air supply fan 5 ') At the end of the outer body 6a so that the secondary air passes through the rear end from the end of the secondary air induction vane 8 and is discharged to the secondary air discharge pipe 9 formed with the discharge direction in the heat source traveling direction. The front end of the burner 7 is located in front of the secondary air discharge pipe (9).
도면중 미설명부호 10은 연소실내의 압력이 일정압력 이상으로 상승될 때 작동하는 안전변이다.In the figure, reference numeral 10 denotes a safety valve that operates when the pressure in the combustion chamber rises above a certain pressure.
이와같이 된 본 고안에 있어 연소실(1)내에서 페타이어나 합성수지 등의 산업폐기물을 연료로하여 연소되어 그 열원이 연소관(6)으로 배출되는 과정은 종래와 동일하다.In the present invention as described above, a process in which the industrial source such as tire or synthetic resin is combusted in the combustion chamber 1 and the heat source is discharged to the combustion tube 6 is the same as in the related art.
그러나 2차공기공급팬(5')에 의하여 공급되는 2차공기가 내체(6a)와 외체(6b) 사이에 형성된 2차공기유도익(8)을 따라 내체(6a)를 순환하여 2차공기배출구(9)로 배출되고 연소관(6)이 미리 약 600℃정도로 가열된 상태이기 때문에 2차공기배출구(9)로 배출되는 2차공기는 예열된 상태로 배출되어 2차공기에 의하여 내체(6a)내의 온도가 저하될 염려가 전혀 없을 뿐만 아니라 2차공기배출구(9)의 배출방향이 열원진행방향으로 되어 있으므로 2차공기가 역류될 염려도 전혀 없게 된다.However, the secondary air supplied by the secondary air supply fan 5 'circulates the inner body 6a along the secondary air induction blades 8 formed between the inner body 6a and the outer body 6b, thereby discharging the secondary air outlet. Since the discharge pipe (9) is discharged to the secondary air discharge port (9) because the combustion pipe (6) is heated to about 600 ° C in advance, the internal air (6a) is discharged in the preheated state. Not only does the internal temperature fall, but the discharge direction of the secondary air discharge port 9 is the heat source advancing direction, so there is no fear of the secondary air flowing back.
따라서 종래와 같이 연소관(6)내의 온도가 저하되거나 2차공기가 역류될 염려가 전혀 없어 항상 정상연소를 하게 되어 페타이어, 합성수지, FRP, 기름걸레 또는 밧데리케이스 등 폐기처리가 곤란한 산업폐기물을 효과적인 연료로 사용할 수 있는 유용한 고안인 것이다.Therefore, there is no fear that the temperature in the combustion pipe 6 will be lowered or the secondary air will not flow backward as in the prior art. It is a useful design that can be used as a fuel.
