Description
본 발명은 탄화가스 생성 보일러용 펠렛의 제조방법에 관한 것으로, 상세하게는 톱밥, 왕겨 및 폐지의 제1 폐기물과 폐타이어, 폐비닐 및 폐플라스틱의 제2 폐기물을 분쇄하여 혼합하면서 펠렛으로 제조함으로써 밀폐된 제1 연소실의 내부에서 1차 연소하는 중에 탄화가스를 생성한 후 다시 제2 연소실에서 2차 연소가 이루어져 휘발성 유기화합물과 공해물질의 발생을 줄이도록 한 탄화가스 생성 보일러용 펠렛의 제조방법에 관한 것이다.The present invention relates to a method for producing a pellet for a hydrocarbon gas-producing boiler, and more specifically, by preparing a pellet while grinding the first waste of sawdust, rice hull and waste paper, and the second waste of waste tire, waste vinyl and waste plastic. Method for producing carbonized gas pelletizing boiler pelletized to reduce the generation of volatile organic compounds and pollutants by generating carbonized gas during the first combustion in the closed first combustion chamber and then in the second combustion chamber. It is about.
일반적으로, 여러 가지의 재료가 혼재하는 상태로 존재하는 가연성 폐기물(음식물 쓰레기, 타이어, 유기 슬러지 등을 포함)은 주로 스토커식 소각로에서 소각하여 왔으나, 다이옥신이 발생하기 때문에 운용중지나 개선이 요구되는 상황이 발생하고 있다.In general, combustible wastes (including food waste, tires, organic sludge, etc.), which are present in a mixed state of various materials, have been mainly incinerated in stalker incinerators, but since dioxin is generated, inoperation or improvement is required. Things are happening.
따라서, 일단 산소가 없는 분위기에서 열분해 기화하고 나서, 이것을 연소하는 가스화 용융식의 유동상형이라든가 킬른형의 소각로가 출현하여 현재에 이르고 있다.Therefore, gas-fired fluidized-bed or kiln-type incinerators, which have been pyrolyzed and evaporated in an oxygen-free atmosphere, are then burned up to the present.
그러나, 이러한 현재의 소각로 역시도 설비비가 매우 높고, 러닝코스트가 높 으며, 대량의 탄산가스가 발생하고, 소각재의 매립이 필요하다는 등의 문제점을 안고 있다.However, these current incinerators also have problems such as high equipment cost, high running cost, large amount of carbon dioxide generated, and the need for landfilling of incinerators.
또한, 가연성 폐기물을 직접 연소하면 나머지는 재로 남게 되고, 이를 연소 용 에어의 취입방법을 개선하여 완전 연소화하는 소각로 및, 가연성 폐기물을 연소되지 않는 분위기에서 열분해 기화하고, 상기 가연가스를 고온 연소하여 나머지를 재로 하는 소각로가 사용되고 있다.In addition, when the combustible waste is directly burned, the remainder remains as ash, and an incinerator which completely improves the blowing method of combustion air, and pyrolyzes and vaporizes the combustible waste in an unburned atmosphere, and burns the combustible gas at a high temperature. Incinerators are used for the rest.
그러나, 이 역시 탄산가스의 배출량이 많고, 전자에서는 다이옥신 문제가, 후자에서는 고가의 설비비와 높은 러닝코스트 문제가 발생되었다.However, this also has a large amount of carbon dioxide emissions, the former dioxin problem, the latter expensive equipment costs and high running cost problems.
더하여, 연소배출가스중의 다이옥신을 저감하는 방법으로서, 에어취입방법의 개선, 고온연소, 다단계연소, 탈염제를 취입하여 연소, 연소배출가스의 급냉, 배출가스 중의 다이옥신을 흡착제거하는 방법 등이 사용되고 있다.In addition, as a method of reducing dioxins in the combustion exhaust gas, improvements in the air blowing method, high temperature combustion, multi-stage combustion, blowing in a desalting agent, combustion, quenching the combustion exhaust gas, and adsorption and removal of dioxins in the exhaust gas, etc. It is used.
그리고, 상기와 같이 연소로에 오존을 취입하는 방법이 일본 특허공개공보 2000-2406호에, 배출가스의 다이옥신을 수산화 마그네슘에 의하여 흡착 분해하는 방법이 일본 특허공개공보 1999-166710호에, 배출가스를 탈염제로 분해처리하는 방법이 일본 특허공개공보 1999-347359호에 각각 개시되어 있다.As described above, a method of blowing ozone into a combustion furnace is disclosed in Japanese Patent Application Laid-Open No. 2000-2406, and a method of adsorbing and decomposing dioxins of exhaust gas with magnesium hydroxide is disclosed in Japanese Patent Laid-Open Publication No. 1999-166710. Are disclosed in Japanese Patent Laid-Open No. 1999-347359, respectively.
그러나, 상기와 같은 배출가스의 처리방법 역시 탄산가스의 배출량이 많고, 전자에서는 다이옥신 문제가, 후자에서는 고가의 설비비 및 높은 러닝코스트 문제가 발생하였다.However, the treatment method of the exhaust gas as described above also has a large amount of carbon dioxide emissions, the former problem of dioxin, the latter expensive equipment cost and high running cost problems.
그리하여 2006년 12월 28일자 특허출원 제10-2006-0136379호(쓰레기 탄화 처리기의 유해물질 연소장치)를 제안하였으며,Thus, a patent application No. 10-2006-0136379 dated December 28, 2006 (Hazardous Substance Combustion System of Garbage Carbonization Processor) was proposed.
2차 연소기를 통하여 열원이 1차 연소기로 공급되어지는 연소기의 열원을 열풍관로를 통해 탄화로를 거쳐 건조로에 공급하고, 상기 건조로에 유입된 열원을 열풍관로를 통해 열교환기를 거쳐 1차 연소기로 리사이클링 하는 유해물질 연소장치에 있어서,The heat source of the combustor in which the heat source is supplied to the primary combustor through the secondary combustor is supplied to the drying furnace through the carbonization furnace through the hot air duct, and the heat source introduced into the drying furnace is recycled to the primary combustor through the heat exchanger through the hot air duct. In the combustion apparatus for hazardous substances,
상기 건조로와 연결된 제1 배출관과 연결되며,Is connected to the first discharge pipe connected to the drying furnace,
일측으로 악취가스 이동관로와 응축수 배출구를 형성한 응축기와 상기 탄화로와 연결된 제2 배출관과 연결되며,It is connected to the condenser and the second discharge pipe connected to the carbonization furnace formed a odor gas flow passage and the condensate outlet to one side,
일측으로 VOC 이동관로와 분진 배출구를 형성한 분진여과장치와 상기 악취가스 이동관로와 VOC 이동관로와 연결되며,It is connected to the dust filtration device and the odor gas flow passage and the VOC flow passage formed a VOC movement pipeline and a dust outlet to one side,
일측으로 인버터팬과 오염물 이동관로를 형성한 챔버와 상기 열교환기에 연결된 열풍관로와 챔버를 연결하는 챔버 열풍관로가 상기 1차 연소기에 연결하여 구성하였다.A chamber formed with an inverter fan and a contaminant moving conduit on one side, and a hot air conduit connected to the heat exchanger and a chamber hot duct connected to the chamber were connected to the primary combustor.
그러나 상기와 같은 쓰레기 탄화 처리기의 유해물질 연소장치에 의하여서는 탄화 및 연소를 위한 구성이 복잡함은 물론, 각종 폐기물을 성형하지 않은 상태로 투입하므로 완전한 탄화가 용이하지 않음은 물론, 불완전 연소 상태의 유해물질을 완전히 연소하지 못하고 분리하여 배출시키게 되므로 또 다른 생활쓰레기를 발생하게 되는 단점이 있었다.However, the toxic material combustion apparatus of the waste carbonization treatment machine is complicated in configuration for carbonization and combustion, and it is not easy to complete carbonization because it does not form various wastes. There was a drawback of generating another household waste because the material is not completely burned and is discharged separately.
또한 2001년 11월 17일자 특허출원 제10-2001-0071660호(탄화연료용 폐기물 재활용 방법)이 제안되었으며,In addition, Patent Application No. 10-2001-0071660 dated November 17, 2001 (Waste recycling method for carbon fuel) was proposed.

상기 탄화공정에서 열분해 기화된 가스는 가스연료실에서 포집·연소하여 이때 발생하는 1000℃이상의 폐열을 열교환기를 통해 대체에너지화하도록 함으로써 탄화공정에서 발생하는 가스를 완전히 연소시켜 무해한 상태로 배기하므로 소각로와 같은 불완전연소에 의해 발생하는 다이옥신 등의 유해가스가 배출되지 않으며, 자연 친화적인 폐기물처리공법임은 물론 탄화물을 생산하여 재활용 자원화하도록 하였다.The pyrolysis-vaporized gas in the carbonization process is collected and burned in the gas fuel chamber so that waste heat of 1000 ° C. or more generated at this time is replaced by a heat exchanger, thereby completely burning the gas generated in the carbonization process and exhausting it in a harmless state. Hazardous gases such as dioxins generated by incomplete combustion are not emitted, and natural waste treatment methods are used to produce carbides for recycling.
그러나 상기와 같은 종래의 탄화연료용 폐기물 재활용 방법에 의하여서는 연소 가능한 폐기물을 단순하게 압축,성형한 후 탄화하여 분쇄하면서 활성탄 등으로 이용하도록 하였으므로 재료를 선별하는 과정이 적어도 3차례 이상 진행되므로 공정이 복잡하여 짐은 물론, 탄화장치를 별도로 구비하여야 하는 번거로움이 있었다. However, according to the conventional waste recycling method for carbonized fuel, since the combustible waste is simply compressed, molded, carbonized and pulverized to be used as activated carbon, the process of selecting materials is performed at least three times. As well as being complicated, there was a hassle to separately provide a carbonization device.

제1 연소실(1)의 내부에 뚜껑(7)을 열고 본 발명의 제조과정을 통하여 제조한 펠렛(100)을 충진시킨 다음 뚜껑(7)을 닫아 밀폐되도록 한다.The lid 7 is opened inside the first combustion chamber 1 to fill the pellet 100 prepared through the manufacturing process of the present invention, and then the lid 7 is closed to be closed.
상기 제1 연소실(1)의 하단에 설치한 망(2)을 통하여 하단에 떨어지는 재를 모아서 처리하는 재처리구(3)에는 송풍기(4)에서 제1 공기 공급관(5)을 통한 공기가 공급되어 망(2)을 통해 공급되도록 한다.Air through the first air supply pipe 5 is supplied from the blower 4 to the reprocessing port 3 for collecting and processing ash falling on the lower end through the net 2 installed at the lower end of the first combustion chamber 1.
