종래에는 가정이나 공장에서 발생하는 각종 폐기물을 처리하기 위한 방법으로 소각시키거나 매립하게 되는데 소각처리방식은 좁은 장소에서 폐기물을 처리할 수 있는 잇점이 있는 반면 폐기물을 완전연소시키기가 어렵기 때문에 유해가스가 발생되어 대기오염을 일으키게 되고, 매립처리방식은 대규모의 매립지가 필요할 뿐 아니라 매립지에서 발생하는 악취 및 대기오염이 심각한 문제로 대두되고 있는 실정이다.Conventionally, it is incinerated or landfilled as a method for treating various wastes generated in homes or factories.Incineration has the advantage of treating wastes in a narrow place, while it is difficult to completely burn wastes. Is generated and causes air pollution, and the landfill treatment method requires a large amount of landfills, and odors and air pollution generated from landfills are a serious problem.

그런데, 최근 여러 연구기관에서 발표한 실험결과 인체에 해로운 유해물질(유해가스)은 700∼1200℃ 온도범위안에서 0.5초 이상 체류시킬 경우, 유해물질은 완전연소와 열분해 과정을 거쳐 인체에 미치는 유해성을 완전제거할 수 있다고 알려져 있으며, 이 결과에 따라 환경청에서도 이를 폐기물 처리에 따른 규정으로 정하고 있다.However, as a result of recent experiments published by various research institutes, if harmful substances (harmful gases) that are harmful to the human body are kept in the temperature range of 700 to 1200 ° C for more than 0.5 seconds, the hazardous substances are harmful to the human body through complete combustion and pyrolysis. It is known that it can be completely removed, and according to the result, the EPA has set this as a regulation for waste disposal.

본 발명의 목적은 모터에 의해 회전하는 로타리관의 내측에 이송날개를 형성하여 승강기로부터 파쇄기를 거쳐 투입되는 폐기물을 투입구를 통해 1차 연소실에 투입하고 고온의 배기가스가 상기 로타리관을 관통하는 배기관을 거쳐 집진기로 송풍되게 하여 로타리관내에서 이송되는 폐기물을 건조시킴으로써 건조된 폐기물에 1차, 2차 연소실에 완전연소될 수 있게 하기 위한 것이다.An object of the present invention is to form a feed vane inside the rotary tube rotated by a motor to inject waste introduced from the elevator through the crusher into the primary combustion chamber through the inlet and exhaust pipe through which the hot exhaust gas passes through the rotary tube. It is intended to be completely burned in the primary and secondary combustion chambers in the dried waste by drying the waste transported in the rotary tube by the air blower to the dust collector through.

이와 같이 된 본 발명의 소각로(1)의 1차 연소실(2)은 내화벽돌(23)로 형성되고 하부에는 버너(24)가 설치되어 있으며, 완전연소되고 남은 재를 처리할 수 있는 청소문(22)이 설치되어 있고, 송풍기(4)에 연결설치된 송풍관(20)의 송풍관(21)은 2차 연소실(3) 방향으로 천공되어 있다.As described above, the primary combustion chamber 2 of the incinerator 1 of the present invention is formed of a refractory brick 23, and a burner 24 is installed at a lower portion thereof, and a cleaning door capable of treating the remaining ashes after being completely burned ( 22 is provided, and the blower tube 21 of the blower tube 20 connected to the blower 4 is drilled in the direction of the secondary combustion chamber 3.

또한, 투입구(30)가 형성된 2차 연소실(3)은 1차 연소실(2)의 상부에 형성되고, 투입구(30)에는 모타(8)에 의해 회전하는 로타리관(6)이 연결설치되어 배기관(61)을 통해 배기되는 배기가스의 열에 의해 이송날개(60)로 이송되는 폐기물을 건조시키게 된다.In addition, the secondary combustion chamber 3, in which the inlet 30 is formed, is formed in the upper part of the primary combustion chamber 2, and the inlet 30 is connected with a rotary pipe 6 which is rotated by a motor 8. The waste conveyed to the transfer blade 60 is dried by the heat of the exhaust gas exhausted through the 61.

상기 로타리관(6)은 모터(8)에 연결된 구동장치(80)에 의해 회전하고 로타리관(6)으로 투입되는 폐기물을 파쇄기(70)에서 잘게 파쇄되는 것이다.The rotary tube 6 is to be crushed finely in the crusher 70 waste rotated by the drive device 80 connected to the motor (8) and introduced into the rotary tube (6).

이렇게 구성된 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way as follows.

제3도에 도시된 바와 같이 공지의 승강기(7)를 구동시켜 파쇄기(70)로 각종 폐기물을 공급하게 되면 파쇄기(70)에서 폐기물이 잘게 파쇄되어 폐기물 공급로(71)를 통해, 제4도에 도시된 바와 같이 로타리관(6)에 투입된다.As shown in FIG. 3, when various kinds of wastes are supplied to the crusher 70 by driving a known elevator 7, the wastes are finely crushed in the crusher 70, and through the waste supply passage 71, FIG. 4. As shown in the rotary tube 6 is injected.

로타리관(6)에 투입된 폐기물을 모터(8)가 구동하여 로타리관(6)이 회전하면 나선형 이송날개(60)에 의해 투입구(30)측으로 이송되는데, 버너(24)의 연소열에 의해 가열된 1차, 2차 연소실(2)(3)의 공기가 배기관(61)을 통해 송풍기(5)를 배기되는 과정에서 이송날개(60)에 의해 이송되는 폐기물을 건조시켜주게 된다.When the rotary tube 6 is rotated by the motor 8 driving the waste introduced into the rotary tube 6, the rotary tube 6 is transferred to the inlet 30 by the spiral feed vane 60, which is heated by the combustion heat of the burner 24. In the process of evacuating the blower 5 through the exhaust pipe 61 through the air in the primary and secondary combustion chambers 2 and 3, the waste transported by the transfer blades 60 is dried.

로타리관(6)을 통과하면서 건조된 폐기물은 제5도에 도시된 바와 같이, 투입구(30)로 투입되어 1차 연소실(2)에서 버너(24)에 의해 1차 연소되고, 1차연소된 폐기물은 송풍관(20)의 송풍공(21)을 통해 2차 연소실(3)쪽으로 송풍되는 공기에 의해 2차 연소실(3)로 올라가게 되며, 2차 연소실(3)쪽으로 송풍되는 공기에 의해 2차 연소실(3)로 올라가게 되며, 2차 연소실(3)에서는 폐기물 1차 연소에 따른 2차 연소실(3) 자체의 온도와 폐기물 연소시 생성된 가연성 물질 및 송풍공(21)을 통한 연소공기의 송풍으로 버너(24)에 의하지 않고도 연소과정이 계속적으로 유지되는 것이다. 이때, 2차 연소실(3)의 온도는 700∼1500℃의 온도를 유지하게 되면 1차 연소시 불완전 연소된 유해물질은 2차 연소실(3)에서 열분해에 의해 2차적인 완전연소과정을 거치게 되고, 이 과정에서 필요한 연소공기는 송풍기(4)에 의해 송풍공(21)으로 공급되는 것으로 상기 버너(24)는 2차 연소실(3)의 온도가 700∼1500℃의 온도를 유지할 수 있도록 가동과 중지가 반복되는 것이다.The waste dried while passing through the rotary tube 6 is introduced into the inlet 30, and first burned by the burner 24 in the primary combustion chamber 2, and the primary burned waste, as shown in FIG. 5. Is raised to the secondary combustion chamber (3) by the air blown toward the secondary combustion chamber (3) through the blowing hole (21) of the blower tube (20), secondary by air blown toward the secondary combustion chamber (3) Ascending to the combustion chamber (3), in the secondary combustion chamber (3) of the combustion air through the temperature of the secondary combustion chamber (3) itself in accordance with the waste primary combustion and the combustible material and blow holes (21) generated during waste combustion. The combustion process is continuously maintained without blowing the burner 24 by the blowing. At this time, if the temperature of the secondary combustion chamber (3) is maintained at a temperature of 700 ~ 1500 ℃ the incomplete combustion of harmful substances during the first combustion is subjected to the second complete combustion process by pyrolysis in the secondary combustion chamber (3) The combustion air required in this process is supplied to the blower 21 by the blower 4, and the burner 24 is operated so that the temperature of the secondary combustion chamber 3 can be maintained at a temperature of 700 to 1500 ° C. The pause is repeated.

이렇게 2차 연소실(3)에서 열분해에 의해 완전연소과정을 거친 배기가스중 일부는 배기관(61)에 연결설치된 송풍기(5)에 의해 강제 송풍되어 집진기(50)(51)를 차례로 거치고 이에 따라 배기가스에 포함된 분진이 여과처리되어 대기오염을 일으킬 염려가 없는 배기가스가 대기중에 방출되는 것으로 나머지 배기가스는 2차 연소실(3) 상부의 배기구(31)를 통해 집진기(52)에서 배기가스에 포함된 분진이 제거되어 대기중으로 방출되기 때문에 소각된 폐기물의 유해가스가 대기중으로 방출되어 대기오염을 일으킬 염려가 없는 것이다.Some of the exhaust gas that has undergone complete combustion by pyrolysis in the secondary combustion chamber 3 is forcibly blown by the blower 5 connected to the exhaust pipe 61 to pass through the dust collectors 50 and 51 in turn and thus exhaust. The dust contained in the gas is filtered to exhaust the exhaust gas into the atmosphere without causing air pollution. The remaining exhaust gas is discharged from the dust collector 52 to the exhaust gas through the exhaust port 31 above the secondary combustion chamber 3. Since the contained dust is removed and released into the atmosphere, there is no risk of the harmful gases of the incinerated waste being released into the atmosphere and causing air pollution.

배기관(6)을 통해 집진기(50)(51)에서 처리되는 상기 배기가스는 배기관(61)을 통과하는 과정에서 로타리관(6)의 이송날개(60)에 의해 연소실(2)(3)으로 투입되는 폐기물을 건조시키게 됨으로써 연소실(2)(3)의 폐기물에는 수분이 포함되지 않아 버너를 끄더라도 폐기물이 연속해서 원활히 연소되어 연료가 절약되고 유해연기가 감소되게 된다.The exhaust gas treated in the dust collectors 50 and 51 through the exhaust pipe 6 is transferred to the combustion chamber 2 and 3 by the transfer blades 60 of the rotary pipe 6 in the course of passing through the exhaust pipe 61. By drying the input waste, the waste in the combustion chamber (2) (3) does not contain moisture, so even if the burner is turned off, the waste is continuously burned smoothly, saving fuel and reducing harmful smoke.

이와 같이 본 발명은 로타리관(6)의 내부에 폐기물을 소각기(1)로 이송시키는 이송날개(60)를 형성하고, 소각기(1)의 연소실(3)과 집진기(51)(52)를 연결하는 배기관(61)이 상기 로타리관(6)을 통과하도록 설치하여 로타리관(6)의 이송날개(60)에 의해 소각기(1)로 투입되는 폐기물이 배기가스 열에 의해 건조될 수 있게 함으로써 폐기물이 원활히 연소될 수 있게 한 것이다.As such, the present invention forms a transfer blade 60 for transferring waste to the incinerator 1 in the interior of the rotary tube 6, and connects the combustion chamber 3 and the dust collector 51, 52 of the incinerator 1. The exhaust pipe 61 is installed so as to pass through the rotary pipe 6 so that the waste introduced into the incinerator 1 by the transfer blades 60 of the rotary pipe 6 can be dried by the exhaust gas heat. It can be burned smoothly.
