본 발명은 다이옥신 제거장치에 관한 것으로서, 좀 더 상세하게는 폐기물 소각시에 발생되는 유해한 다이옥신을 열분해하여 제거하는 새로운 구조의 다이옥신 제거장치에 관한 것이다.The present invention relates to a dioxin removal device, and more particularly, to a dioxin removal device of a new structure that pyrolyzes and removes harmful dioxin generated during waste incineration.

종래에 생활쓰레기나 기타 각종 폐기물을 소각처리하는 과정에서 불완전연소로 인해 인체에 유해한 다이옥신이 발생되고 있다. 특히, 소각 후에 배기가스와 함께 배출되면서 집진기에서 포집되는 재(비회)에는 다량의 다이옥신이 포함되어 있다. 이러한 다이옥신은 암을 유발하는 등 인체에 치명적인 것으로 알려져 있다. 종래에 이러한 다이옥신의 배출량을 줄이는 방법으로는 소각로의 연소작용을 완전연소에 가깝도록 하는 방법이 주로 채택되었으나, 완전연소를 달성하는 것은 쉽지 않으며, 일단 발생된 다이옥신, 특히 소각후의 집진기에 포집된 재에 함유된 다이옥신을 효과적으로 제거하는 방법은 알려져 있지 않다.Conventionally, in the process of incineration of household waste or other wastes, dioxin that is harmful to the human body is generated due to incomplete combustion. In particular, the ash (fly ash) collected by the dust collector while being discharged together with the exhaust gas after incineration contains a large amount of dioxins. This dioxin is known to be fatal to the human body, causing cancer. Conventionally, the method of reducing the emission of dioxins has been mainly adopted to close the combustion operation of the incinerator to full combustion, but it is not easy to achieve the complete combustion, and the ash collected in the dioxins, especially the dust collector after incineration, is generated. There is no known method for effectively removing dioxins contained in.

본 발명은 전술한 바와같은 종래의 쓰레기 소각처리의 부산물인 다이옥신의 처리상의 문제점에 착안하여 제안된 것으로서, 소각장치의 집진기에서 포집되어 다이옥신이 다량 함유된 소각재로부터 다이옥신을 효율적으로 열분해 제거하는 새로운 구조의 다이옥신 제거장치를 제공하고자 하는 것이다.The present invention has been proposed in view of the problem of the treatment of dioxins, which are by-products of the conventional waste incineration process, as described above, and is a new structure for efficiently pyrolyzing and removing dioxins from incinerators containing a large amount of dioxins collected in a dust collector of an incinerator. To provide a dioxin removal device of.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 제1도와 제2도는 본 발명의 실시예에 따른 다이옥신 제거장치의 구성도로서, 도시된 바와같이, 먼저 집진기에 수집되며 다량의 다이옥신을 함유하는 비회가 수집되어 하단의 정량공급장치(12)를 통해 일정량씩 공급하는 호퍼(10)가 연결관(14)을 통해 열분해부(20)를 이루는 외부케이싱(21)의 유입공(23)에 접속된다. 이 열분해부(20)는 양단에 유입공(23)과 유출공(24)이 각각 형성되고, 그 사이에는 다수의 가열관(22)이 연결부재(28)에 의해 간격을 이루어 평행하게 배치된다. 그리고, 이 다수의 가열관(22)의 외부에는 히터(25)가 둘러싸여서 가열관(22)을 대략 400 내지 500℃로 가열시킨다. 이와같이 가열관(22)이 이격배치됨으로 인해, 히터(25)에 의해 균등하게 가열되게 된다. 한편, 가열관(22)과 외부케이싱(21)은 비회의 원활한 흘러내림을 위해 경사지게 배치된다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 1 and 2 is a block diagram of a dioxin removing device according to an embodiment of the present invention, as shown, first collected in the dust collector and fly ash containing a large amount of dioxin is collected to provide a fixed quantity feeder 12 at the bottom The hopper 10, which is supplied at a predetermined amount, is connected to the inlet 23 of the outer casing 21 forming the pyrolysis unit 20 through the connecting pipe 14. The pyrolysis unit 20 has inlet holes 23 and outlet holes 24 formed at both ends thereof, and a plurality of heating tubes 22 are disposed in parallel with each other by a connection member 28. . The heater 25 is surrounded by the outside of the plurality of heating tubes 22 to heat the heating tubes 22 to approximately 400 to 500 ° C. As the heating tube 22 is spaced apart in this way, it is heated evenly by the heater 25. On the other hand, the heating tube 22 and the outer casing 21 are inclined to smoothly flow down the fly.

상기 외부케이싱(21)의 둘레에는 체인기어(29)가 장착되어 도시안된 구동기구에 의해 저속회전하도록 구성된다. 따라서, 이 외부케이싱(21)과 가열관(22)이 함께 회전된다. 또한 이 체인기어(29)의 일측에는 외부케이싱(21)과 일체로 캠부재(41)가 장착되고, 이 캠부재(41)의 둘레에는 단차부(42)가 형성된다. 이 캠부재(41)의 외주면에는 타격부재(43)가 이 캠부재(41)에 탄성적으로 접촉되며 슬라이드 가능하게 구성된다. 이 타격부재(43)는 캠부재(41)를 타고 이동하다가 단차부(42)에서 가열관(22)에 충돌하여 가열관(22)을 타격하게 된다. 따라서, 이 가열관(22) 속으로 흐르는 미세분말인 비회가 가열관(22)의 내벽에 부착되지 않고 원활하게 이송되도록 한다. 또한, 상기 가열관(22)의 각각의 선단부에는 주걱형태의 블레이드(46)가 부착되어 가열관(22)의 회전시에 피처리물인 분말상의 비회를 퍼서 가열관(22)의 유입공으로 투입시킨다.A chain gear 29 is mounted around the outer casing 21 so as to rotate at low speed by a driving mechanism not shown. Thus, the outer casing 21 and the heating tube 22 rotate together. In addition, one side of the chain gear 29, the cam member 41 is mounted integrally with the outer casing 21, the step portion 42 is formed around the cam member 41. On the outer circumferential surface of the cam member 41, the striking member 43 is elastically contacted with the cam member 41 and configured to be slidable. The striking member 43 moves on the cam member 41 and collides with the heating tube 22 at the step 42 to strike the heating tube 22. Therefore, fly ash, which is fine powder flowing into the heating tube 22, is smoothly transported without being attached to the inner wall of the heating tube 22. In addition, a spatula-shaped blade 46 is attached to each tip portion of the heating tube 22 to inject powder fly ash, which is an object to be processed, into the inlet hole of the heating tube 22 when the heating tube 22 is rotated. .

상기 열분해부(20)의 외부케이싱(21)의 후단에는 유출공(24)을 통해 배출덕트(26)가 접속되고, 이 배출덕트(26)는 또 다른 보조덕트(27)를 거쳐 냉각부(30)로 연통된다. 상기 배출덕트(26)의 상단에는 배기가스를 배출하는 배기구(44)가 형성된다. 냉각부(30)의 둘레에는 냉각수가 순환되는 냉각수자켓(34)이 부설되어 이 속을 흐르는 비회를 급속하게 냉각시킨다.A discharge duct 26 is connected to the rear end of the outer casing 21 of the pyrolysis unit 20 through an outlet hole 24, and the discharge duct 26 passes through another auxiliary duct 27 to provide a cooling unit ( 30). An exhaust port 44 for discharging the exhaust gas is formed at an upper end of the discharge duct 26. A cooling water jacket 34 in which cooling water is circulated is installed around the cooling unit 30 to rapidly cool the fly ash flowing therein.

이러한 구성을 가진 본 발명에 따른 장치의 작동을 설명하면, 집진기에서 수집되며 다량의 다이옥신을 함유한 소각재인 비회가 호퍼(10)를 통해 일정량씩 열분해부(20)로 공급된다. 외부케이싱(21)과 가열관(22)은 체인기어(29)에 의해 저속회전함으로써 그 속을 흐르는 비회가 균등하게 가열되면서 원활하게 이송될 수 있다. 또한, 캠부재(41)에 접촉되는 타격부재(43)는 주기적으로 외부케이싱(21) 및 가열관(22)을 타격하여 비회가 원활하게 흐르도록 한다. 그리고, 가열관(22)의 입구에는 블레이드(46)가 설치되어 함께 회전함으로써 외부케이싱(21)의 유입공(23)으로 들어온 비회를 퍼서 가열관(22)의 입구로 투입한다.Referring to the operation of the apparatus according to the present invention having such a configuration, the fly ash, which is collected in the dust collector and contains a large amount of dioxins, is supplied to the pyrolysis unit 20 by a predetermined amount through the hopper 10. The outer casing 21 and the heating tube 22 are rotated at low speed by the chain gear 29 so that the fly ash flowing therein can be smoothly transferred while being heated evenly. In addition, the striking member 43 in contact with the cam member 41 periodically strikes the outer casing 21 and the heating tube 22 so that the fly ash flows smoothly. In addition, the blade 46 is installed at the inlet of the heating tube 22 and rotates together, thereby dispersing fly ash entering the inlet 23 of the outer casing 21 and introducing it into the inlet of the heating tube 22.

이와같이, 가열관(22)으로 투입된 비회는 대략 400 내지 500℃ 정도로 가열되면서 열분해된다. 이때, 다이옥신류를 단독으로 열분해하는 데는 600℃ 이상의 온도를 필요로 하지만, 비회 속에 함유된 다이옥신은 재에 포함되어 있는 금속류의 촉매작용으로 이보다 낮은 450℃ 정도에서 다이옥신의 염소가 제거되는 탈염소화반응이나 산소가교를 차단하는 등의 반응을 하여 다이옥신을 소멸시키게 된다. 한편, 가열탈염소화반응에 의해 생성된 배기가스는 배출덕트(26)에 형성된 배기구(44)를 통해 소각로로 보내진다. 이어서 다이옥신이 열분해된 비회는 냉각부(30)로 도입되어 급랭됨으로써 다이옥신의 재활성화, 즉 다이옥신 재생성반응이 억제된다.In this way, the fly ash injected into the heating tube 22 is pyrolyzed while being heated to about 400 to 500 ° C. At this time, the pyrolysis of dioxins alone requires a temperature of 600 ° C. or higher, but the dioxins contained in ash are catalyzed by the metals contained in the ash, and the dechlorination reaction of dioxins is removed at about 450 ° C. Or dioxins by the reaction of blocking oxygen crosslinking. On the other hand, the exhaust gas generated by the heat dechlorination reaction is sent to the incinerator through the exhaust port 44 formed in the exhaust duct 26. Then, fly ash pyrolyzed by dioxin is introduced into the cooling unit 30 to be quenched to suppress reactivation of dioxin, that is, dioxin regeneration.

이와같이 다이옥신이 열분해된 비회는 시멘트로 고형화처리되어 매립 등의 방법으로 최종처리되게 된다.As such, fly ash pyrolyzed by dioxin is solidified with cement and finally treated by landfilling or the like.

이상에서 설명한 본 발명에 따르면, 다량의 다이옥신을 함유하는 비회 등의 소각재를 열분해하고 냉각처리하고, 재활성화를 막음으로써 다이옥신을 제거할 수 있어서 다이옥신으로 인한 환경오염이나 인체에 미치는 유해한 영향을 줄일 수 있게 된다.According to the present invention described above, dioxins can be removed by pyrolyzing and cooling incineration ash such as ash containing a large amount of dioxins, and preventing reactivation, thereby reducing environmental pollution or harmful effects on the human body. Will be.
