Description
본 발명은 고구마 전분박을 압착 탈수하여 함수율 40 %의 고구마 전분박을 형성하는 과정과, 무연괴탄을 100 메쉬로 분쇄하여 함수율 30 %의 무연괴탄 분말을 형성하는 과정과, 상기 고구마 전분박 30 ∼ 50 중량%와 상기 무연괴탄 분말 50 ∼ 70 중량%를 혼합 교반하여 혼합물을 형성하는 과정과, 상기 혼합물을 일정한 크기의 괴상 형태로 성형하는 과정과, 상기 성형물을 함수율 20 %가 되도록 건조하는 과정으로 구성되어 고구마 전분의 제조 과정에서 발생하는 폐기물인 고구마 전분박을 에너지원으로 재활용하고 무연괴탄의 소비를 절감하는 고구마 전분박과 무연괴탄을 이용한 혼합성형탄의 제조 방법에 관한 것이다.The present invention is a process of forming a sweet potato starch meal of 40% moisture content by compressing and dehydrating sweet potato starch foil, the process of forming anthracite coal powder of 30% moisture content by grinding anthracite coal to 100 mesh, and the sweet potato starch foil 30 ~ Mixing and stirring 50% by weight and 50 to 70% by weight of the anthracite powder to form a mixture, forming the mixture into a block of a predetermined size, and drying the molding to a water content of 20%. The present invention relates to a method for producing mixed coal briquettes using sweet potato starch meal and anthracite coal, which recycles sweet potato starch meal, which is a waste generated in the manufacturing process of sweet potato starch, as an energy source and reduces the consumption of anthracite coal.
고구마 전분의 제조 과정에서 원료로 사용되는 고구마 중량의 약 30 %에 해당되는 고구마 전분박이 발생하는데, 국내에서는 연평균 약 20,000 톤의 고구마 전분박이 발생하며, 발생하는 고구마 전분박의 일부는 가축 사료로 재활용되지만 대부분은 지상 매립되어 폐기 처분되는 실정이다. 이러한 고구마 전분박은 98 중량% 이상이 섬유질로 구성되어 연소시 약 3,600 ∼ 4,000 ㎉/㎏의 열량을 발생할 수 있으나 가정용, 산업용으로 활용하기에는 열량이 부족하다는 문제점이 있다. 또한 각종 석탄류는 다른 종류의 화석에너지에 비하여 에너지 효율이 우수하여 산업용의 에너지원으로 널리 활용되고 있으나 국내의 채굴 가능한 석탄 매장량은 약 15 억톤에 불과하며 채굴되는 석탄의 열량도 6,000 ㎉/㎏ 이하로서 외국산 석탄보다 낮기 때문에 매년 다량의 석탄을 외국에서 수입하고 있는 실정이다.In the manufacturing process of sweet potato starch, sweet potato starch which is about 30% of the weight of sweet potato used as raw material is generated.In Korea, annually about 20,000 tons of sweet potato starch is generated, and some of the sweet potato starch produced is recycled as livestock feed. However, most of them are landfilled and disposed of. Such sweet potato starch foil is composed of more than 98% by weight of fiber may generate about 3,600 ~ 4,000 ㎉ / ㎏ calories when burned, but there is a problem that the calories are insufficient to use for home, industrial use. In addition, various coals are widely used as energy sources for industrial use because they are more energy efficient than other types of fossil energy, but domestic coal reserves are only about 1.5 billion tons, and the amount of coal mined is under 6,000 ㎉ / ㎏. As it is lower than foreign coal, a large amount of coal is imported from foreign countries every year.
본 발명의 목적은 고구마 전분박을 압착 탈수하여 형성되는 함수율 40 %의 고구마 전분박 30 ∼ 50 중량%와, 무연괴탄을 분쇄하고 100 메쉬로 분말화하여 형성되는 함수율 30 %의 무연괴탄 분말 50 ∼ 70 중량%를 혼합하고, 상기 혼합물을 일정한 크기의 괴상 형태로 성형하고 20 %의 함수율로 건조하여 구성되어 가정용, 산업용으로 활용 가능한 5,000 ∼ 6,000 ㎉/㎏의 열량을 지닌 혼합성형탄의 제조 방법을 제공하는데 있다.An object of the present invention is 30 to 50% by weight of sweet potato starch meal of 40% moisture content formed by compressive dehydration of sweet potato starch foil, and anhydrous anthracite powder 50 to 30% moisture content formed by pulverizing anthracite coal and powdering it into 100 mesh. 70 wt% is mixed, the mixture is molded into a block of a certain size and dried at a moisture content of 20% to provide a method for producing mixed coal having a calorific value of 5,000 ~ 6,000 ㎉ / ㎏ can be used for home and industrial use It is.
본 발명의 고구마 전분박과 무연괴탄을 이용한 혼합성형탄의 제조 방법은 고구마 전분의 제조 과정에서 부산물로 발생하는 고구마 전분박을 압착 탈수하여 함수율 40 %의 고구마 전분박을 형성하는 과정과, 무연괴탄을 100 메쉬로 분쇄하여 함수율 30 %의 무연괴탄 분말을 형성하는 과정과, 상기 고구마 전분박 30 ∼ 50 중량%와 상기 무연괴탄 분말 50 ∼ 70 중량%를 혼합 교반하여 혼합물을 형성하는 과정과, 상기 혼합물을 일정한 크기의 괴상 형태로 성형하는 과정과, 상기 성형물을 함수율 20 %가 되도록 건조하는 과정으로 구성되는 특징이 있다.The method for producing mixed coal using sweet potato starch meal and anthracite coal of the present invention is a process of forming sweet potato starch foil having a water content of 40% by compressing and dehydrating sweet potato starch meal generated as a by-product during the production of sweet potato starch. Pulverizing to 100 mesh to form anthracite coal powder having a water content of 30%, mixing and stirring 30 to 50% by weight of the sweet potato starch meal and 50 to 70% by weight of the anthracite coal powder to form a mixture, and the mixture It is characterized by consisting of the process of molding to form a block of a constant size, and the process of drying the molding to a water content of 20%.
고구마 전분박과 무연괴탄 분말을 일정한 중량비로 혼합 교반하고 성형하는 과정을 거쳐서 혼합성형탄을 구성하는데, 고구마 전분박의 열량은 3,600 ∼ 4,000 ㎉/㎏이며 무연괴탄의 열량은 6,000 ∼ 8,000 ㎉/㎏이므로 고구마 전분박 30 ∼ 50 중량%와 무연괴탄 분말 50 ∼ 70 중량%를 혼합 교반하고 성형하여 가정용, 산업용으로 활용 가능한 열량인 5,000 ∼ 6,000 ㎉/㎏의 혼합성형탄을 구성하는데, 혼합성형탄의 연소 효율이나 경제성을 고려하여 고구마 전분박 40 중량%와 무연괴탄 분말 60 중량%를 혼합 교반하고 성형하여 무연갈탄과 비슷한 열량을 지닌 혼합성형탄을 구성하는 것이 바람직하다.Sweet potato starch meal and anthracite coal powder are mixed and stirred to form a certain weight ratio to form mixed coal. 30 to 50% by weight of sweet potato starch meal and 50 to 70% by weight of anthracite coal powder are mixed and agitated to form 5,000 to 6,000 kW / kg of mixed coal which can be used for home and industrial purposes. In consideration of economics, it is preferable to mix and stir 40% by weight of sweet potato starch meal and 60% by weight of anthracite coal powder to form mixed coal having a calorie content similar to that of anthracite lignite.
고구마 전분의 제조 과정에서 부산물로 발생하는 고구마 전분박은 함수율이 60 ∼ 70 %이며, 이러한 고함수율의 고구마 전분박을 압착 탈수하여 함수율이 40 %인 고구마 전분박을 형성한다. 고구마 전분박의 함수율이 40 %를 초과하면 상기 고구마 전분박이 부패되기 쉽고, 고구마 전분박의 함수율이 40 % 미만이면 상기 고구마 전분박의 덩어리가 형성되어 무연괴탄 분말과 혼합하고 압착 성형하는 것이 곤란해진다.Sweet potato starch meal produced as a by-product during the production of sweet potato starch has a water content of 60 to 70%, and decompresses and dehydrates the high water content sweet potato starch to form a sweet potato starch meal having a water content of 40%. When the water content of sweet potato starch is more than 40%, the sweet potato starch is easily rotted, and when the water content of sweet potato starch is less than 40%, agglomerates of sweet potato starch are formed, making it difficult to mix with anthracite powder and press molding. .
무연괴탄을 100 메쉬로 분쇄하여 함수율 30 %의 무연괴탄 분말을 형성한다. 무연괴탄 분말이 미세할수록 상기 무연괴탄 분말과 고구마 전분박이 용이하고 균일하게 혼합되므로, 무연괴탄을 분쇄하고 분쇄된 무연괴탄 분말을 100 메쉬로 체질하여 미세한 무연괴탄 분말을 형성한다.Anthracite coal is pulverized to 100 mesh to form anthracite coal powder having a water content of 30%. As the anthracite powder is finer, the anthracite powder and sweet potato starch meal are easily and uniformly mixed, so that the anthracite coal is pulverized and the pulverized anthracite powder is sieved to 100 mesh to form fine anthracite powder.
상기와 같이 형성된 고구마 전분박 30 ∼ 50 중량%와 무연괴탄 분말 50 ∼ 70 중량%를 혼합하고 교반하여 상기 고구마 전분박과 무연괴탄 분말의 혼합물을 형성한다.30 to 50% by weight of sweet potato starch foil formed as described above and 50 to 70% by weight of anthracite coal powder are mixed and stirred to form a mixture of the sweet potato starch foil and anthracite powder.
상기와 같이 형성된 혼합물의 보관 및 취급이 용이하도록 상기 혼합물을 일정한 크기의 괴상 형태로 성형하여 성형물을 형성한다.In order to facilitate storage and handling of the mixture formed as described above, the mixture is molded into a block of a certain size to form a molding.
상기 성형물을 함수율 20 %가 되도록 건조하여 혼합성형탄을 완성한다. 혼합성형탄의 함수율이 20 %를 초과하면 상기 혼합성형탄이 불완전 연소되기 쉽고, 혼합성형탄의 함수율이 20 % 미만이면 상기 혼합성형탄의 보관 및 취급시 상기 혼합성형탄이 부스러지기 쉽다.The molding is dried to a water content of 20% to complete the mixed coal. When the water content of the mixed coal exceeds 20%, the mixed coal tends to be incompletely burned, and when the water content of the mixed coal is less than 20%, the mixed coal is brittle when the mixed coal is stored and handled.
