본 고안은 쓰레기를 연소시키기 위하여 쓰레기를 교반시키면서 이송되는 방향과 연소가스를 반대방향으로 향류시키므로서 쓰레기와 연소가스가 골고루 접촉하게 되어 건조가 촉진되는 동시에 건류가 촉진되어 효과적으로 연소시키게 되고 쓰레기와 향류하고 있는 연소가스는 재연소로에서 재연소시켜 미연소 및 휘발연소분을 완전연소시킨 후 복사전열부를 거쳐 모래를 이용한 폐열회수장치로 공급되어 폐열을 회수시킨 뒤 전기집진기 및 세정탑등을 통과시켜 공해물질을 완전제거시킨후 대기중에 배출되게 한 것이다.In order to burn the garbage, the present invention flows the waste gas in the opposite direction while stirring the waste, and the waste gas and the combustion gas are in uniform contact with each other, thereby promoting drying and at the same time promoting dry flow, effectively burning the garbage and countercurrent. The combustion gas is re-burned in the reburn furnace to completely burn the unburned and volatile combustion components, and is then supplied to the waste heat recovery system using sand through the radiant heat transfer unit to recover the waste heat, and then passed through an electrostatic precipitator and a washing tower. After the material is completely removed, it is released to the atmosphere.

종래에 본인이 선등록 받은 실용신안등록 제46412호는 쓰레기의 교반 장치가 없어 쓰레기의 건조 및 건류가 완전하게 이루어지지 못하여 불완전연소의 요인이 되었을 뿐 아니라, 폐열회수장치가 고체입자를 이용한 것이 아니어서 절탄기의 외주에 수트등이 쌓이게되면 이를 제거하기에 번거로움이 있는 문제점이 있었다.Utility Model Registration No.46412, which was previously registered in advance, has not become a source of incomplete combustion due to the lack of waste drying and drying, and the waste heat recovery system does not use solid particles. If the suit is piled up on the outer periphery of the cutter, there was a problem in that it is troublesome to remove it.

본 고안은 이와같은 문제점을 적게하기 위하여 고안한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to reduce such problems as described in detail by the accompanying drawings.

경사지게 설치한 로타리킬른(1)의 하부에 연소부(2)와 재처리부(3)를 형성하고 전방에는 상호 연통되게 재연소로(4)를 설치하여 내상부에서 연통로(5)와 일정간격이 유지되게 복사열판(4a)을 설치하고 재연소로(4)의 전방에는 쓰레기벙커(6a)를 설치하여 그 내부에 설치된 쓰레기 투입호퍼(6)에 유압푸셔(6b)를 롤 설치하여 로터리킬른(1)내로 쓰레기를 투입케하고 연통로(5)와 연결시킨 모래를 이용한 폐열회수장치의 상부동체(7)내에 급수가열 절단기(8)와 다단의 다공판으로된 모래가열장치(9)를 설치하고 배기가스는 전기집진기(10)와 세정탑(11)을 거쳐 대기중으로 배출되게하고 상부동체(7)의 하부에는 로터리밸브(12)를 설치하여 하부동체(7a)와 연관시키고 하부동체(7a)내에는 다단의 다공판으로된 공기예열장치(13)를 설치한 하부에는 공기공급관(14)의 다수설치된 모래배출호퍼(15)를 설치하여 바켓엘리베이터(16)와 연통되게하여서 된 것이다.Combustion part 2 and reprocessing part 3 are formed in the lower part of the rotary kiln 1 which is inclined, and a recombustion path 4 is installed in front of each other so that the communication path 5 and the predetermined distance are separated from the upper part. Install the radiant heat plate 4a so as to be maintained, and install the waste bunker 6a in front of the reburn furnace 4, and install the hydraulic pusher 6b in the waste injecting hopper 6 installed therein. In the upper fuselage (7) of the waste heat recovery device using the sand connected to the communication path (5), the feed water heating cutter (8) and the sand heater (9) made of multi-stage porous plates The exhaust gas is discharged into the atmosphere through the electrostatic precipitator 10 and the washing tower 11, and a rotary valve 12 is installed at the lower part of the upper body 7 to associate with the lower body 7a and lower body 7a. In the lower part where the air preheating device 13 made of a multi-stage perforated plate is installed, a plurality of air supply pipes 14 Deployed by installing a sand discharge hopper 15 will be in communication with the hayeoseo bucket elevator (16).

미설명부호 17은 모래탱크, 18은 크레인, 19은 버어너, 20은 교반돌기, 21은 송풍기이다.Reference numeral 17 is a sand tank, 18 is a crane, 19 is a burner, 20 is a stirring protrusion, 21 is a blower.

이상과 같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

쓰레기벙커(6a)내에 들어 있는 쓰레기를 투입크레인(18)으로 쓰레기투입호퍼(6)에 투입하면 유압푸셔(6b)에 의하여 회전하고 있는 로터리킬른(1)내로 투입시키면 로터리킬른(1)이 경사지게 설치되어 있어 서서히 내려가는데 이때 교반돌기(20)에 의하여 쓰레기가 상승하였다가 떨어지면서 교반이 이루어지므로 연소부(2)에서 연소된 연소가스 쓰레기의 이송방향과 반대방향으로 항류하게 되어 연소가스의 고열에 의하여 건조가 촉진되며 이와같이 건조된 쓰레기는 점차하강하면서 점차가열되어 휘발분은 건류가스화되어 일부가연분은 가스화가 된다. 쓰레기가 연소부(2)에 다다르면 공급된 공기와 혼합되어 연소가 이루어진다. 한편, 연소가스는 건류된 가스와 혼합되어 로터리킬른 전방에 설치한 재연소로(4)로 공급되어 재연소하게 되는데 이때 재연소로(4)의 온도가 낮은 경우에는 버어너(19)에 의하여 보조연료를 공급시켜 재연소를 촉진시킨다. 이와같이 재연소된 가스는 복사전열판(4a)에 열을 복사시킨 뒤 연통로(5)에 연결시킨 모래를 이용한 폐열회수장치의 상부동체(7)로 공급되어 수관으로된 절탄기(8)를 지나면서 가열하게 되고 계속상승하는 가스는 다단의 다공판으로된 모래가열장치(9)를 지나 낙하되는 모래를 상승하는 가스에 의하여 가열되어 낙하하면서 절탄기에 부딪치게 되므로 절탄기(8)의 전열을 촉진시키는 동시에 절탄기(8)에 부착된 수트를 청소해주게 된다.When the waste contained in the waste bunker 6a is introduced into the waste input hopper 6 by the input crane 18, the waste is introduced into the rotary kiln 1 rotated by the hydraulic pusher 6b so that the rotary kiln 1 is inclined. Since the waste is raised and dropped by the stirring protrusion 20, the stirring is performed, and the stirring is performed so that the waste flows in the opposite direction to the conveying direction of the combustion gas waste combusted in the combustion unit 2, and thus the high temperature of the combustion gas. Drying is promoted by this, and the dried waste is gradually heated while gradually falling down, and the volatiles are converted into dry gas, and some of the combustibles are gasified. When the rubbish reaches the combustion section 2, the waste is mixed with the supplied air and combustion occurs. On the other hand, the combustion gas is mixed with the carbonized gas and supplied to the reburn furnace 4 installed in front of the rotary kiln to be reburned. At this time, when the temperature of the reburn furnace 4 is low, the auxiliary fuel is burned by the burner 19. To promote reburning. The reburned gas is supplied to the upper fuselage (7) of the waste heat recovery apparatus using sand connected to the communication path (5) after radiating heat to the radiant heat transfer plate (4a) and passing through the water piper (8). As the gas is heated and continues to rise, the sand falling through the multi-layered porous plate sand heater 9 is heated and dropped by the rising gas so as to collide with the pelletizer while promoting the heat transfer of the pelletizer 8. At the same time, the soot attached to the cutter 8 is cleaned.

절탄기(8a)를 거친 가스는 상승하면서 내려오는 모래 절탄기(8a)를 거친 가스는 상승하면서 내려오는 모래와 접하여 모래를 가열하고 온도가 떨어진 가스는 전기집진기(10)와 세정탑(11)를 거쳐 대기중으로 배출되므로 가스에 의한 공해방지를 하게된다.The gas passing through the blower 8a rises and descends while the gas passing through the blower 8a rises in contact with the rising sand and heats the sand, and the gas whose temperature has fallen is the electrostatic precipitator 10 and the cleaning tower 11. It is discharged into the atmosphere through the to prevent pollution by gas.

이와같은 본 고안의 소각장치는 종래형식으로는 완전연소가 매우힘든 주방쓰레기등의 저질고수분 쓰레기도 완전하게 연소할 수 있을뿐 아니라 연소용 공급공기의 적당한 조절에 의하여 발열량이 매우 높은 고발열량 쓰레기도 노내과열없이 쉽게 연소시킬 수 있고 재연소로(4)에서 1000도 이상의 고열에 장시간 가스를 체류시킬 수 있으므로 다이옥신등 부수적인 공해물질 발생도 최대한 억제할 수 있으며 처리쓰레기의 종류도 스러지등의 고수분 쓰레기로부터 폐유폐가스등도 재연소실에 공급시켜 연소시킬 수 있으므로 가연성 물은 거의 소각시킬 수 있는 이점이 있는 것이다.The incineration device of the present invention can not only completely burn low quality and high moisture waste such as kitchen waste, which is very difficult to burn in the conventional type, but also generate high calorific value waste with high calorific value by proper control of combustion supply air. It can be burned easily without overheating in the furnace and gas can be kept for a long time at a high temperature of over 1000 degrees in the reburn furnace (4), so that it is possible to suppress the occurrence of additional pollutants such as dioxins as well as high moisture such as waste. Since waste waste gas and the like can be supplied from the waste to the reburn chamber, the combustible water is almost incinerated.
