In addition to the hassle of manually performing a series of processes of injecting air into the combustion chamber and igniting it, it is difficult to set the operation point, operation efficiency is lowered, and when the fire is turned off in the secondary combustion chamber due to uncertain gas emission, Is not burned and is discharged to the outside to contaminate the environment.

본 발명은 이러한 문제점을 해결하기 위하여 2차연소실의 예열부에 온도센서를 부착하여 예열부가 소정온도로 예열된 상태가 되면 1차연소실의 점화구로 전달하여 점화버너를 설정시간 동안 점화시키고 이어서 연소노즐에 의해 폐기물을 연소시키며 연소과정에서 발생한 건류가스는 2차연소실로 보내져서 연소가 이루어지도록 하며 2차연소실 내에 광센서를 부착하여 연소상태를 감지할 수 있도록한 것이다.In order to solve this problem, the present invention attaches a temperature sensor to the preheating part of the secondary combustion chamber so that when the preheating part is preheated to a predetermined temperature, it is delivered to the ignition port of the primary combustion chamber to ignite the ignition burner for a set time, and then the combustion nozzle. By burning wastes, dry gas generated in the combustion process is sent to the secondary combustion chamber for combustion, and an optical sensor is attached to the secondary combustion chamber to detect the combustion state.

상기의 제어수단은 중앙연산처리장치로 컨트롤되는 제어부(40)에 의해 행해진다.Said control means is performed by the control part 40 controlled by the central processing unit.

도면중 미설명 부호 21은 2차연소실의 온도를 감지하는 온도센서, 101은 연소실 개폐문, 102는 안전변, 103은 투입구이다.In the drawings, reference numeral 21 denotes a temperature sensor for sensing the temperature of the secondary combustion chamber, 101 a combustion chamber opening door, 102 a safety valve, and 103 an inlet.

이와같이 된 본 발명의 소각기에서는 폐타이어나 폐합성고무, 폐합성수지 등의 폐기물을 소각하기 위해서 1차연소실(10) 내에 투입시킨 다음 2차연소실(20)의 예열부(23)에 설치된 예열관(24)으로 점화용 공기유입관(27)을 통해 공기를 유입시킴과 동시에 점화노즐(26)을 예열점화버너(25)를 가동하여 점화시켜 예열부(23)를 약 300-500℃의 온도로 설정온도까지 가열시키고 예열온도센서(30)에 의해 설정온도가 감지되면 제어부(30)에서 1차연소실(10)의 점화구(11)에 전달하여 연소점화버너(12) 가동으로 점화노즐(13)에 의해 소정시간 동안 점화시킨후 타이머 설정시간이 지나면 연소점화버너(12)의 가동은 중단되고 차단판(14)으로 점화구(11)를 차단시킨다.In the incinerator according to the present invention, a preheating tube installed in the preheating unit 23 of the secondary combustion chamber 20 is introduced into the primary combustion chamber 10 to incinerate waste tires, waste synthetic rubber, waste synthetic resin, and the like. 24) the air is introduced through the ignition air inlet pipe 27, and at the same time, the ignition nozzle 26 is operated by ignition by operating the preheating burner 25 to ignite the preheater 23 to a temperature of about 300-500 ° C. When heated to a set temperature and the set temperature is detected by the preheating temperature sensor 30, the control unit 30 transmits the ignition port 11 of the primary combustion chamber 10 to operate the combustion ignition burner 12 to ignite the nozzle 13. After the ignition for a predetermined time by the timer set time elapses, the operation of the combustion ignition burner 12 is stopped and the ignition port 11 is blocked by the blocking plate 14.

상기와 같이 1차연소실(10)에 점화가 이루어지면 공기유입관(16)이 개방되면서 연소노즐(15)에 의한 1차연소실(10) 내의 폐기물을 연소시키게 되며 연소과정에서 발생한 건류가스는 가스토출구(17)를 통해 2차연소실(20)의 예열부(23)에 유입됨과 동시에 연소용 공기유입관(27′)이 개방되면서 유입되는 공기가 건류가스와 합류되어 2차연소실(20)에서 건류가스를 완전 연소시키게 된다.When the primary combustion chamber 10 is ignited as described above, the air inlet pipe 16 is opened to burn waste in the primary combustion chamber 10 by the combustion nozzle 15. Air flowing into the preheating unit 23 of the secondary combustion chamber 20 through the discharge port 17 and at the same time as the combustion air inlet pipe 27 'is opened, the air introduced therein joins the dry gas and is discharged from the secondary combustion chamber 20. Dry gas is completely burned.

이때, 연소용 공기유입관(27′)으로 유입되는 공기는 예열된 상태의 예열부(23) 벽체 외주면을 따라 거치면서 데워지므로 연소효율을 한층 높여주게 되며 아울러 연소시에는 제어부(40)에 의해 예열점화버너(25)의 가동은 중단되는 것이다.At this time, the air flowing into the combustion air inlet pipe (27 ') is heated along the outer circumferential surface of the wall of the preheater (23) in the preheated state to increase the combustion efficiency further and at the time of combustion by the control unit 40 The operation of the preheating ignition burner 25 is stopped.

이렇게 폐기물을 1차연소실(10)에서 연소하는 과정에서 발생한 건류가스는 2차연소실(20)에서 완전연소시키게 되며 건류가스연소과정에서 불확실한 연소로 인하여 연소불꽃의 밝기가 설정치 보다 낮아지면 광센서(22)에 의해 이를 감지하여 예열점화버너(25) 가동으로 점화시키는 방법으로 예열부(23)를 가열하여 완전연소를 이룰수 있도록 한다.The dry gas generated in the process of burning waste in the primary combustion chamber 10 is completely burned in the secondary combustion chamber 20. When the brightness of the combustion flame is lower than the set value due to the uncertain combustion in the dry gas combustion process, the optical sensor ( 22) to detect this and to ignite the preheating ignition burner (25) operation to heat the preheater (23) to achieve complete combustion.

한편, 건류가스가 2차연소실(20)에서 연소되지 않는 상태가 되면 광센서(22)에 의해 감지된 신호가 제어부(40)에 전달되어 1차연소실(10)의 연소노즐(15)에 유입되는 공기를 차단함과 아울러 건류가스토출구(17)를 개폐밸브(19)로 차단하여 건류가스가 연소되지 않은 상태에서 배출되지 않도록 하고 예열점화버너(25)를 가동하여 예열부(23) 온도를 설정치로 만든다음 재차 1차연소실(10)에서 폐기물을 연소시키는 과정에서 발생한 건류가스를 2차연소실(20)에서 완전연소시켜 배출시키게 된다.On the other hand, when dry gas is not burned in the secondary combustion chamber 20, a signal sensed by the optical sensor 22 is transmitted to the control unit 40 to flow into the combustion nozzle 15 of the primary combustion chamber 10. In addition to blocking the air, the dry gas stream outlet 17 is blocked by the on-off valve 19 to prevent the dry gas from being discharged in a non-combusted state, and the preheating ignition burner 25 is operated to maintain the preheating part 23 temperature. After making the set value, the dry gas generated in the process of burning waste in the primary combustion chamber 10 is completely burned and discharged in the secondary combustion chamber 20.

또, 1차연소실(10)의 폐기물연소작업이 완료되어 건류가스가 2차연소실(20)에 유입되지 않게되면 소정시간 내에 광센서(22)에 의해 예열점화버너(25)의 가동이 3차례정도 반복되는 것을 제어부(40)에 전달하여 소각기 전체의 작동을 자동으로 중단시키게 된다.In addition, when the waste combustion operation of the primary combustion chamber 10 is completed and dry gas is not introduced into the secondary combustion chamber 20, the operation of the preheating burner 25 is performed three times by the optical sensor 22 within a predetermined time. By repeating the repeating degree to the control unit 40 will automatically stop the operation of the entire incinerator.

이와같이 본 발명은 1차연소실에서 폐기물을 연소시키고 연소과정에서 발생한 건류가스는 2차연소실에서 완전연소시켜 배출시키는 일련의 과정이 완전자동으로 이루어지고 불완전연소가스의 배출은 완전차단함으로서 환경오염을 방지할 수 있는 효과가 있는 것이다.As described above, the present invention burns waste in the primary combustion chamber and dry gas generated in the combustion process is completely burned in the secondary combustion chamber, and a series of processes are completely performed and discharge of incomplete combustion gas is completely blocked to prevent environmental pollution. There is an effect that can be done.
