It relates to a heating torrefaction device.
세계에서 가장 많은 신재생에너지로서 바이오매스는 낮은 에너지와 질량 밀도, 고수분으로 증발에 열화적 변환 비용을 증대하고, 친수성 성질로서 장기저장이 어려우며, 종래의 열적처리 시에 심한 연기 및 다량의 오염물질 발생으로 에너지원으로서 이용의 한계가 있다.As the world's most renewable energy, biomass increases the cost of thermal conversion to evaporation due to its low energy, mass density, and high moisture, and is difficult to store for a long time due to its hydrophilic nature, and severe smoke and large amounts of pollution during conventional thermal treatment. There is a limit to its use as an energy source due to the generation of matter.
최근에 200-300℃의 조건에서 바이오매스를 처리하는 반타화에 대한 개발이 고조 되고 있다. 반탄화는 에너지 밀도, 소수성, 가연성, 반응성, 분쇄성, 연소, 가스화 특성 등의 바이오매스 성질을 현저하게 향상한다. Recently, the development of anti-aging for processing biomass under conditions of 200-300 ° C. is increasing. Torrefaction significantly improves biomass properties such as energy density, hydrophobicity, combustibility, reactivity, millability, combustion and gasification properties.
바이오매스 반타화 기술은 반응에 필요한 열원의 공급 방식에 따라 고온의 연소가스 혹은 반탄화 가스를 반탄화로 내에 공급하여 고온의 가스와 바이오매스가 열교환설비를 거치지 않고 직접 접촉하는 직접가열방식과 열교환설비에 고온의 가스를 통과시킨 후 바이오매스를 간접적으로 열처리하는 간접가열방식으로 나눌수 있다. 상기 직접가열방식은 별도의 열교환설비를 거치지 않기 대문에 바이오매스로의 열전달 효율은 높지만, 가열가스 내 산소가 존재할 경우 연소반응에 의한 반탄화물 수율 감소로 반탄화 공정의 효율이 저감되고, NOx, SOx 등과 같은 대기오염물질 발생량이 증가하는 문제점이 있다.Biomass bantanization technology supplies high-temperature combustion gas or torrefaction gas into the torrefaction furnace according to the heat source supply method required for the reaction, and the direct heating method and heat exchange in which the high-temperature gas and biomass come into direct contact without going through a heat exchange facility It can be divided into an indirect heating method in which biomass is indirectly heat-treated after passing high-temperature gas through the facility. The direct heating method has high heat transfer efficiency to biomass because it does not go through a separate heat exchange facility, but when oxygen is present in the heating gas, the efficiency of the torrefaction process is reduced due to a decrease in the torrefaction yield due to the combustion reaction, NOx, There is a problem in that the amount of air pollutants such as SOx increases.
따라서 최근에는 반탄화물 수율을 높일 수 있는 간접열교환방식의 반탄화 기술이 이슈화가 되고 있다. 그러나 바이오매스를 간접적으로 가열하는 구조의 경우는 반탄화로 내부에서 부분적으로 고온부가 형성되고, 반응온도 구배가 크게 형성되는 경우가 있으며 반탄화 제품의 수율이 감소된다. 또한, 간접열교환방식의 반탄화공정에서는 투입되는 원료의 성분에 따라 COS, VOCs, NH3, H2S 등 오염물질이 발생할 뿐만 아니라 악취가 발생하는 문제점이 있다.Therefore, in recent years, torrefaction technology of an indirect heat exchange method capable of increasing the yield of torrefaction has become an issue. However, in the case of a structure that indirectly heats biomass, a high-temperature zone is partially formed inside the torrefaction furnace, and a large reaction temperature gradient is sometimes formed, and the yield of the torrefaction product is reduced. In addition, in the torrefaction process of the indirect heat exchange method, there is a problem in that pollutants such as COS, VOCs, NH 3 , H 2 S and the like are generated depending on the components of the input raw material, as well as odor.
특허문헌 1은 원료물질을 열처리하는 내통, 상기 내통을 둘러싸면서 열풍의 이동경로를 형성하는 외통, 상기 외통은 구역판에 의해서 구역이 나뉘어지고, 상기 구역으로 공급되는 열풍의 공급량을 제어할 수 있는 열풍공급부를 포함하는, 주반응부인 내통의 외부에 열풍을 공급하는 간접식 로터리 킬른 반응기를 개시하였으나, 특히 반응기 지름이 큰 반응기 내부의 온도 구배 문제를 빠른 시간내에 완전히 해결하기에는 역부족이다.Patent Document 1 discloses an inner cylinder for heat treatment of raw materials, an outer cylinder for forming a movement path of hot air while surrounding the inner cylinder, and the outer cylinder is divided into zones by a zone plate and can control the supply amount of hot air supplied to the zone An indirect rotary kiln reactor including a hot air supply unit and supplying hot air to the outside of the inner cylinder, which is the main reaction unit, has been disclosed, but it is not enough to completely solve the temperature gradient problem inside the reactor with a large reactor diameter in a short time.
특허문헌 2는 석탄 건조를 위한 로터리 킬른 건조기에 관한 것이고, 구체적으로는 원통형 회전 반응기, 상기 내부를 관통하여 방사형으로 위치하고 내부에 스팀 혹은 고온 배가스가 흐르는 다수의 배관, 상기 반응기 내부벽면에는 석탄을 소정 높이까지 끌어올렸다 반응기 회전에 따라 아래로 떨어지게 하는 소정크기의 플레이트 시편을 포함하는 석탄 건조용 간접식 로터리 킬른 건조기를 개시하였다. 특허문헌 2는 반탄화보다 낮은 온도 조건을 요구하는 건조를 목적으로 하고 있고, 반응기 내부에 설치되는 배관이 많아 구조가 복잡하고 유지보수가 어려울뿐만 아니라, 바이오매스와 같이 석탄보다 성상이 복잡하고 밀도가 작은 물질들이 반응기의 회전 및 중력에 의해 반응기 후단으로 이동하는 과정에서 축적되어 반응기 내부 온도를 상승시키고, 제품의 품질을 저하시키는 문제에 대해 인식하지 못하고 있다.Patent Document 2 relates to a rotary kiln dryer for drying coal, and specifically, a cylindrical rotary reactor, a plurality of pipes located radially through the inside and flowing steam or high-temperature exhaust gas therein, and coal on the inner wall surface of the reactor. An indirect rotary kiln dryer for drying coal including a plate specimen of a predetermined size that is raised to a height and then dropped down according to the rotation of the reactor is disclosed. Patent Document 2 aims at drying that requires lower temperature conditions than torrefaction, and has many pipes installed inside the reactor, making the structure complicated and difficult to maintain, as well as having a more complex property and density than coal, such as biomass. There is no awareness of the problem that small substances accumulate in the process of moving to the rear end of the reactor by rotation and gravity of the reactor, thereby increasing the temperature inside the reactor and degrading the quality of the product.
또한, 특허문헌 1과 특허문헌 2는 반탄화 과정에서 생성되는 오염물질을 제거하기 위한 기술에 대해서도 인식하지 못하고 있다.In addition, Patent Document 1 and Patent Document 2 do not recognize the technology for removing contaminants generated in the torrefaction process.
이와 같이 본원발명에서 중요한 문제로 인식하고 있는 반탄화 장치에 있어서, 반응기 내부 온도구배를 효과적으로 해결하고, 오염물질의 외부 배출을 줄이면서, 균일한 품질의 반탄화 생성 고형연료을 안정적으로 외부로 배출시킬 수 있는 기술은 아직까지 제시되지 않았다.As such, in the torrefaction device recognized as an important problem in the present invention, it is possible to effectively solve the temperature gradient inside the reactor, reduce the external discharge of pollutants, and stably discharge the torrefaction produced solid fuel of uniform quality to the outside. A possible technique has not yet been presented.
