산업의 발전으로 필요한 에너지의 많은 부분을 화석연료에 의존하고 있으나 화석연료는 제한적이고 사용시에 각종 유해물질을 발생시키고 있으므로 화석연료를 대체할 수 있는 친환경적 에너지를 찾는데 많은 관심을 기울이고 있다.Although much of the energy required for industrial development depends on fossil fuels, since fossil fuels are limited and generate various harmful substances during use, much attention is paid to finding eco-friendly energy that can replace fossil fuels.
또한, 산업의 발전으로 각종 쓰레기 특히 산업폐기물이나 생활 폐기물의 발생량이 많아져 이를 처리하기 위해서 큰 비용을 소비하고 있다. 이에 폐기물을 이용하여 에너지를 생산할 수 있는 기술이 개발되고 있는 실정이다.In addition, with the development of industry, the amount of various wastes, especially industrial wastes and domestic wastes, increases, and large costs are consumed to treat them. Accordingly, a technology capable of producing energy using waste is being developed.
일반적으로, 유기물은 열분해(thermal decomposition)를 통해 숯과 같은 탄소고체, 오일 또는 가연성 가스 등의 열분해 생성물이 된다.In general, organic matter becomes thermal decomposition products such as carbon solids such as charcoal, oil or combustible gas through thermal decomposition.
예를 들어, 목재를 열분해하면 목초액, 나무 타르, 목탄 등을 제조할 수 있고, 석탄을 열분해 하여 석탄 가스, 타르, 코크스 등을 얻기도 한다.For example, wood vinegar, wood tar, charcoal, etc. can be produced by pyrolysis of wood, and coal gas, tar, coke, etc. can be obtained by pyrolysis of coal.
특히, 최근에는 석탄, 석유 등의 화석 에너지를 대체할 수 있는 대체 에너지로써 상기 유기물을 이용하는 고형연료로서, 바이오매스(bio mass)에 관한 연구 및 개발이 활발하게 진행되고 있다.In particular, recently, as a solid fuel using the organic matter as an alternative energy capable of replacing fossil energy such as coal and oil, research and development on biomass has been actively conducted.
한편, 커피박은 바이오매스의 한 종류로서 목재, 볏짚 등 일반적으로 고형 연료화 되고 있는 바이오매스와는 달리 셀룰로오스, 헤미셀룰로오스, 리그닌 이외에 유지성분이 16% 이상 함유되어 있고 회분함유량 1.75%로 10% 이상인 석탄에 비해 현저히 낮으며, 발열량 4,664kcal/kg으로 1급 목재브리켓 발열량 기준인 4,300kcal/kg을 상회하는 연료 특성이 우수한 바이오매스 자원이다.On the other hand, coffee waste is a type of biomass, and unlike biomass that is generally converted into solid fuels such as wood and rice straw, it contains more than 16% of oil and fat components in addition to cellulose, hemicellulose, and lignin, and has an ash content of 1.75%, which is equivalent to more than 10% of coal. It is a biomass resource with excellent fuel characteristics, with a calorific value of 4,664kcal/kg, exceeding the calorific value standard of 4,300kcal/kg for first-class wood briquettes.
이러한 중요한 에너지 자원임에도 불구하고 산업폐기물로 분류되어 현재까지 에너지 자원으로서의 이용가치를 인식하지 못한 점도 있었지만 에너지효율을 높일 수 있는 적절한 방법을 찾지 못하고 있는 실정이다.Although it is an important energy resource, it has been classified as industrial waste and has not been recognized for its usefulness as an energy resource until now, but there is no proper way to increase energy efficiency.
또한, 커피박은 석탄에 버금가는 발열량을 가지고 있지만 가루상태나 브리켓 상태의 커피박을 단일로 연소시키면 연소속도가 느리고 불꽃을 일으키지 못하며 연소속도의 지연으로 에너지 효율이 낮아지는 문제점이 있었다.In addition, coffee waste has a calorific value comparable to that of coal, but when the coffee waste in a powder or briquette state is burned alone, the combustion rate is slow, the flame cannot be generated, and the combustion rate is delayed, resulting in low energy efficiency.
한편, 왕겨는 벼의 도정과정에서 대량으로 생성되는 부산물로서 국내에서 연간 약 백만 톤이 발생함은 물론 세계각국에서도 수천만 톤이 발생하여 그 물량이 충분함과 아울러 연중 도정으로 항상 일정량이 발생하므로 안정적인 공급이 가능할 뿐만 아니라, 저렴하며, 탄화왕겨가 최종 소비지 근처에서 생산되어 그 유통이 편리하다는 점에서 고형화 연료로 사용하기에 적합하다.On the other hand, rice hull is a by-product produced in large quantities during the milling process of rice. Approximately one million tons are generated annually in Korea, as well as tens of millions of tons in countries around the world. It is suitable for use as a solidified fuel in that it is not only possible to supply, inexpensive, and carbonized rice hull is produced near the final consumption place and its distribution is convenient.
그러나 왕겨는 상기와 같이 여러 가지 장점을 갖는 우수한 소재임에도 불구하고 유류 대체 연료인 연탄이나 화목 등의 고형연료에 비해 연료로서의 이용률이 매우 낮고, 대부분의 경우에 있어서는 농업용 퇴비재료로 이용되거나 축산업용으로 사용되었으며, 일부 탄화처리하여 토양개선제로 활용하고 있는 실정이다.However, although rice hull is an excellent material having various advantages as described above, its utilization rate as a fuel is very low compared to solid fuels such as briquettes and firewood, which are alternative fuels for oil. In most cases, it is used as a compost material for agriculture or for livestock It has been used, and some of them are carbonized and used as soil improvers.
이와 같이 왕겨가 대체 연료로서의 이용률이 낮은 이유는 성분조성이 탄소 35%, 수소 5%, 산소 39%, 회분 20%로 이루어져 연소온도가 화목이나 톱밥 등의 고형연료보다 상대적으로 높고, 규소를 다량 함유한 판상의 구조로 되어 있어 발열량이 부족하기 때문이었다.The reason for the low utilization rate of rice hull as an alternative fuel is that its composition is 35% carbon, 5% hydrogen, 39% oxygen, and 20% ash, so its combustion temperature is relatively higher than that of solid fuels such as firewood or sawdust, and it contains a large amount of silicon. This was because the calorific value was insufficient due to the plate-like structure containing
또한, 왕겨는 작은 입자의 형태로 이루어져 있기 때문에 고형화 연료로 제조하기 위해서는 응집제를 혼합하여야 하는데, 별도의 응집제를 사용함으로 인하여 결과적으로 고형화 연료의 원가가 상승하는 문제점이 있었기 때문이다.In addition, since the rice hull is in the form of small particles, a coagulant must be mixed in order to manufacture it as a solidified fuel, and as a result, the cost of the solidified fuel increases due to the use of a separate coagulant.
그러므로 커피박과 반탄화된 왕겨를 적용하여 고형연료로서의 효율이 극대화될 수 있도록 한 커피박과 반탄화된 왕겨를 재자원화하는 고효율 친환경 고형연료 및 그의 제조방법에 대한 연구 및 개발이 요구되는 실정이다.Therefore, research and development of high-efficiency eco-friendly solid fuel and its manufacturing method for recycling coffee waste and torrefied rice hull, which can maximize efficiency as a solid fuel by applying coffee waste and torrefied rice hull, are required. .
상기와 같은 문제점을 해결하기 위하여, 본 발명은 고형화처리 기술을 이용하되 폐기되어지는 커피박과 반탄화 왕겨를 친환경적이고 독성물질이 없는 접착제를 혼합시켜 고형화하여 커피박 및 반탄화 왕겨를 재자원화하는 브리켓성형된 고효율 고형연료를 제조함으로써 석탄발전소에서 신재생에너지공급의무화(RPS)를 달성하기 위해 확보해야 하는 신재생에너지로 적용할 수 있도록 한 커피박과 반탄화된 왕겨를 재자원화하는 고효율 친환경 고형연료 및 그의 제조방법을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention uses a solidification treatment technology, but the discarded coffee waste and torrefied rice husk are mixed with an environmentally friendly and non-toxic adhesive to solidify the coffee waste and torrefied rice husk for recycling. By manufacturing briquette-shaped high-efficiency solid fuel, it is a high-efficiency, eco-friendly solid material that recycles coffee waste and torrefied rice hulls so that they can be applied as renewable energy that must be secured to achieve the Renewable Energy Supply Mandatory (RPS) in coal power plants. Its object is to provide a fuel and its manufacturing method.

By manufacturing high-efficiency solid fuel, it is possible to stably deal with environmental problems as a coffee accessory of coffee grounds generated by local governments and at the same time significantly reduce the processing cost of coffee accessories.

도 1은 본 발명에 따른 커피박과 반탄화된 왕겨를 재자원화하는 고효율 친환경 고형연료의 제조방법을 단계별로 나타낸 블록도이다.1 is a block diagram showing a step-by-step method for producing a high-efficiency eco-friendly solid fuel for recycling coffee waste and torrefied rice hulls according to the present invention.
먼저, 본 발명의 바람직한 실시예에 따른 커피박과 반탄화된 왕겨를 재자원화하는 고효율 친환경 고형연료는 커피박과 반탄화된 왕겨를 재자원화하는 고효율 고형연료로서, 반탄화 왕겨 70~95중량%, 커피박 5~30중량%를 포함하며, 반탄화 왕겨와 커피박이 혼합된 혼합원료 100중량부에 대하여 접착제 10~50중량부가 혼합된다.First, the highly efficient eco-friendly solid fuel for recycling coffee waste and torrefied rice hulls according to a preferred embodiment of the present invention is a high-efficiency solid fuel for recycling coffee waste and torrefied rice hulls, and contains 70 to 95% by weight of torrefied rice hulls. , 5 to 30% by weight of coffee waste, and 10 to 50 parts by weight of an adhesive is mixed with respect to 100 parts by weight of a mixed raw material in which torrefied rice hulls and coffee waste are mixed.
이러한 커피박과 반탄화된 왕겨를 재자원화하는 고효율 고형연료는 브리켓성형기를 통해 브리켓 타입으로 성형됨이 바람직한 것이다.It is preferable that the high-efficiency solid fuel for recycling such coffee waste and torrefied rice husk is molded into a briquette type through a briquette molding machine.
여기서, 반탄화 왕겨와 커피박이 혼합된 혼합원료 100중량부에 대하여 접착제 10~50중량부가 혼합되는 이유는 접착제의 함량이 10중량부 이하가 되면 접착력이 낮아서 브리켓 타입으로 성형이 되지 않는 문제가 있으며, 50중량부 이상이 되면 과도한 접착력으로 성형 후 탈착에 문제가 있음에 기인한 것이다.Here, the reason why 10 to 50 parts by weight of the adhesive is mixed with respect to 100 parts by weight of the mixed raw material mixed with torrefied rice husk and coffee waste is that when the content of the adhesive is less than 10 parts by weight, the adhesive strength is low, so there is a problem that it cannot be molded into a briquette type. , If it is more than 50 parts by weight, it is due to a problem in detachment after molding due to excessive adhesive strength.
또한, 상기와 같은 본 발명에 따른 커피박과 반탄화된 왕겨를 재자원화하는 고효율 고형연료에서의, 상기 접착제는 10~60%의 농도인 수성 접착제로 제공되되, 폴리비닐알콜, 폴리비닐아세테이트, 폴리아크릴레이트, 전분, 변성전분 중 선택된 1종 또는 2종 이상이 혼합된 것으로 제공되는 것이 바람직하다.In addition, in the high-efficiency solid fuel for recycling coffee waste and torrefied rice husk according to the present invention as described above, the adhesive is provided as a water-based adhesive having a concentration of 10 to 60%, polyvinyl alcohol, polyvinyl acetate, It is preferable to provide one or a mixture of two or more selected from polyacrylate, starch, and modified starch.
더욱이, 상기와 같은 본 발명에 따른 커피박과 반탄화된 왕겨를 재자원화하는 고효율 고형연료에서의, 상기 반탄화 왕겨 및 커피박의 입자 크기는 10~400 mesh의 것으로 적용되는 것이 바람직한 것이다.Moreover, in the high-efficiency solid fuel for recycling coffee waste and torrefied rice husk according to the present invention as described above, it is preferable that the torrefied rice hull and coffee waste have a particle size of 10 to 400 mesh.
이때, 반탄화 왕겨 및 커피박의 입자 크기에 대하여 10~400 mesh의 것으로 적용되는 이유는 반탄화 왕겨 및 커피박의 입자 크기가 10 mesh 이하이면 겉보기 비중이 낮아져서 성형시 공극이 발생하며, 밀도가 낮아져 열량을 올릴 수가 없고, 400 mesh 이상이면 미세한 입자로 인하여 접착제와의 혼합 등에 문제가 있어서 성형에 문제가 있음에 기인한 것이다.At this time, the reason why 10 to 400 mesh is applied to the particle size of torrefied rice husk and coffee waste is that if the particle size of torrefied rice hull and coffee waste is 10 mesh or less, the apparent specific gravity is lowered, and voids are generated during molding, and the density is It is due to the fact that it is not possible to increase the amount of heat because it is lowered, and if it is 400 mesh or more, there is a problem in molding due to problems such as mixing with adhesives due to fine particles.
또한, 반탄화 왕겨 및 커피박의 입자 크기는 동일하게 10~400 mesh의 것으로 적용되는 것으로, 이러한 이유는 입자 크기가 서로 상이할 경우, 혼합시 균일한 혼합을 이룰 수가 없기 때문이다.In addition, the particle size of the torrefied rice hull and the coffee waste is equally applied to those of 10 to 400 mesh, and this is because when the particle sizes are different from each other, uniform mixing cannot be achieved during mixing.
한편, 상기와 같은 본 발명에 따른 커피박과 반탄화된 왕겨를 재자원화하는 고효율 고형연료에서의, 상기 반탄화 왕겨 및 커피박은 수분 함량이 0.1%가 되도록 건조하여 사용되는 것이 바람직하다.On the other hand, in the high-efficiency solid fuel for recycling coffee waste and torrefied rice husk according to the present invention as described above, it is preferable that the torrefied rice hull and coffee waste are dried to a moisture content of 0.1% before use.
상기와 같이, 반탄화 왕겨 및 커피박의 수분 함량이 0.1%가 되도록 건조하여 사용하는 이유는 수분 함량이 높을 경우에는 브리켓 타입으로 성형하기 위한 접착제의 함량을 일정하게 유지할 수 없는 문제가 있기 때문이다.As described above, the reason why the moisture content of the torrefied rice husk and coffee waste is dried to be 0.1% is because when the moisture content is high, there is a problem in that the content of the adhesive for molding into a briquette type cannot be maintained constant. .
전술한 바와 같은 본 발명에 따른 커피박과 반탄화된 왕겨를 재자원화하는 고효율 고형연료는 반탄화 왕겨를 주성분으로 하여 열량을 보조하는 개념으로 커피박을 사용하며, 이때 커피박도 왕겨와 마찬가지로 반탄화된 것으로 제공됨이 바람직하다.As described above, the high-efficiency solid fuel for recycling coffee waste and torrefied rice husk according to the present invention uses coffee waste as a concept of supplementing heat by using torrefied rice hull as a main component.

여기서, 커피박은 원료 수급의 문제가 있고, 흡습니아 스웰링(swelling) 등의 문제로 주원료로 사용하기에 어려움이 있으므로, 본 발명에서는 부 성분으로 사용된 것이다.Here, coffee grounds are used as a sub-component in the present invention because there is a problem of raw material supply and demand, and it is difficult to use it as a main raw material due to problems such as absorption and swelling.
아울러, 일반적인 왕겨는 열량이 낮아 연료로 효능이 없으므로, 본 발명에서는 반탄화된 반탄화 왕겨를 적용한 것이다.In addition, since general rice hulls are low in heat and are ineffective as a fuel, in the present invention, torrefied torrefied rice hulls are applied.
