본 발명은 축산 오물을 이용한 고체연료의 제조방법에 관한 것으로, 특히 동물기름과 인화성이 높은 석유계 기름의 혼합물에 환경오염물인 가축의 배설물 분말을 혼합하여 일정한 크기로 성형한 축산 오물을 이용한 고체연료의 제조방법에 관한 것이다.The present invention relates to a method for producing solid fuel using livestock waste, and in particular, a solid fuel using livestock waste molded into a certain size by mixing animal waste and animal waste powder of environmental pollutants with a mixture of animal oil and highly flammable petroleum oil. It relates to a manufacturing method of.

일반적으로 화력의 에너지원으로 이용되는 연료는 크게 나누어 목탄, 코오크스, 석탄과 같은 고체연료와, 알콜, 벤졸, 가솔린과 같은 액체연료와, LPG, LNG와 같은 기체연료로 구분된다.In general, fuels used as energy sources of thermal power are divided into solid fuels such as charcoal, coke and coal, liquid fuels such as alcohol, benzol and gasoline, and gaseous fuels such as LPG and LNG.

상기한 고체연료, 액체연료 및 기체연료는 매장량이 제한되어 있거나 제조비용이 높기 때문에 값싸고 매장량이 풍부한 새로운 에너지원을 개발하기 위한 많은 연구가 진행되고 있다.Since the solid fuel, liquid fuel and gaseous fuel have limited reserves or high manufacturing costs, many studies are being conducted to develop new energy sources which are inexpensive and rich in reserves.

한편, 축산업의 발달에 따라 이로부터 배출되는 축산 오물은 생활하수 및 공장폐수와 함께 상수원 등을 오염시키는 주범으로 대두되고 있어, 축산업의 발전을 저해하는 큰 요인이 되고 있다.On the other hand, livestock waste discharged from the development of livestock industry has emerged as a major contaminant for polluting water supply, along with domestic sewage and factory wastewater, and has become a major factor that hinders the development of livestock industry.

따라서, 소규모 축산농가에서는 축산 오물을 완전하게 처리하지 못하고 있고, 대규모 축산기업은 축산 오물을 톱밥 등을 이용하여 비료화하거나 기타 다른 정화방법으로 처리하고 있으나, 처리비용과 시설비가 높은 문제점이 있었다.Therefore, small livestock farms do not completely handle livestock waste, and large livestock companies have processed the livestock waste using fertilizer or other purification methods using sawdust, etc., but the processing cost and facility cost are high.

일부 축산 오물을 고체연료로서 제조한 예가 제안되고 있으나 이들은 모두 연소시에 화력이 낮거나 다소 냄새가 나기 때문에 실용화가 어려운 문제점을 안고 있다.Some examples of producing livestock waste as a solid fuel have been proposed, but all of them have a problem of difficulty in practical use because they have a low thermal power or a slight odor during combustion.

본 발명자는 이러한 문제를 해결하기 위하여 값싼 동물성 기름과 인화성과 휘발성이 높은 기름을 부원료로 하여 혼합비율과 혼합방법 등에 대한 많은 연구를 거듭한 결과 상기한 문제를 저렴한 제조비용으로 모두 해결할 수 있는 고체연료를 발견하게 되었다.In order to solve this problem, the inventors have conducted many studies on mixing ratio and mixing method using inexpensive animal oil and highly flammable and highly volatile oil as a subsidiary material, and can solve all the above problems with low manufacturing cost. Was found.

따라서 본 발명은 이러한 종래기술의 문제점을 감안하여 안출된 것으로, 그 목적은 동물성 기름과 인화성이 높은 석유계 기름의 혼합물에 환경오염물인 가축의 배설물 분말을 혼합하여 일정한 크기로 성형함에 의해 축산 오물을 환경 친화적이며 저비용 높은 인화성을 갖는 새로운 에너지원으로 처리할 수 있는 축산 오물을 이용한 고체연료의 제조방법을 제공하는데 있다.Accordingly, the present invention has been made in view of the problems of the prior art, and its object is to produce livestock wastes by mixing animal fecal powders of animal pollutants, which are environmental pollutants, into a mixture of animal oil and highly flammable petroleum oil. The present invention provides a method for producing solid fuel using livestock waste that can be treated as a new energy source that is environmentally friendly and has low cost and high flammability.

도 1은 본 발명에 따른 축산 오물을 이용한 고체연료의 제조방법을 설명하기 위한 제조 공정도이다.1 is a manufacturing process chart for explaining a method for producing a solid fuel using livestock waste according to the present invention.

상기한 목적을 달성하기 위하여, 본 발명은 석유계 기름과 동물성 기름을 중량비로 1 : 5.66-19의 비율로 혼합된 일차 혼합물을 균일하게 혼합하여 1-2일 정도 정치시키는 단계와, 숙성된 일차 혼합물과 가축의 배설물 분말을 중량비로 1 : 2.5-3의 비율로 반죽하여 일정한 크기로 성형하여 건조시키는 단계로 구성되는 것을 특징으로 하는 축산 오물을 이용한 고체연료의 제조방법을 제공한다.In order to achieve the above object, the present invention comprises the step of uniformly mixing the primary mixture mixed with petroleum oil and animal oil in a weight ratio of 1: 5.66-19 by standing 1-2 days, and aged primary It provides a method for producing a solid fuel using livestock waste, characterized in that the step of mixing the mixture and livestock feces powder in a weight ratio of 1: 2.5-3 by molding to a certain size and dried.

상기한 바와같이 본 발명에서는 값싼 동물성 기름과 인화성이 높은 석유계 기름을 혼합시킴에 의해 발화시의 인화성을 높이며, 여기에 매우 값싼 가축의 배설물을 건조시켜 분쇄한 분말을 혼합하여 일정한 크기로 성형함에 의해 축산 오물을 환경 친화적으로 처리가 가능하며 이로부터 얻어지는 고체연료는 저비용 높은 인화성을 갖는 새로운 에너지원으로 사용이 가능하다.As described above, in the present invention, by mixing a cheap animal oil and a highly flammable petroleum-based oil to increase the flammability at the time of ignition, to dry the excrement of very cheap livestock to form a predetermined size by mixing the pulverized powder This makes it possible to treat livestock wastes in an environmentally friendly way, and the solid fuel obtained therefrom can be used as a new energy source with low cost and high flammability.

이하에 상기한 본 발명을 바람직한 실시예가 도시된 첨부도면을 참고하여 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

첨부된 도 1은 본 발명에 따른 축산 오물을 이용한 고체연료의 제조방법을 설명하기 위한 제조 공정도로서, 본 발명에 따른 고체연료의 제조방법은 먼저 석유계 기름과 동물성 기름을 1 : 5.66-19 중량비율로 혼합된 일차 혼합물을 균일하게 혼합하여 1-2일 정도 정치시킨다(S1).1 is a manufacturing process chart for explaining a method for producing a solid fuel using livestock waste according to the present invention, the method for producing a solid fuel according to the present invention is first petroleum-based oil and animal oil 1: 5.66-19 weight The primary mixture mixed in proportion is uniformly mixed and left to stand for 1-2 days (S1).

상기한 동물성 기름은 예를들어, 우지나 돈지 등을 가열하여 추출된 원액을 사용하며, 비용이 저렴한 어떤 동물성 기름도 사용 가능하다.The above-mentioned animal oil is, for example, using the stock solution extracted by heating the tallow or pork, etc., any animal oil of low cost can be used.

석유계 기름은 적정의 휘발성과 인화성을 보유하며 가급적 비용이 저렴한 기름으로서 등유나 벙커씨유, 경유 등이 사용 가능하다.Petroleum-based oils have moderate volatility and flammability, and are inexpensive oils. Kerosene, bunker seed oil and diesel oil can be used.

석유계 기름과 동물성 기름의 혼합비율은 중량비로 1 : 5.66 이하로 되는 경우 고체연료의 인화성과 화력이 좋아지나 제조원가의 지나친 상승을 초래하며, 1 : 19 이상으로 되는 경우는 높을수록 일차 혼합물이 조기에 경화되는 현상이 나타나기 때문에 중량비로 1 : 5.66-19 사이로 정한다.When the ratio of petroleum oil and animal oil is less than 1: 5.66 in weight ratio, the flammability and thermal power of solid fuel may be improved, but the production cost may be excessively increased. The hardening phenomenon appears in the weight ratio of 1: 5.66-19.

석유계 기름과 동물성 기름의 혼합은 먼저 반고체 상태의 돈지나 우지와 같은 동물성 기름을 가열하여 액체상태로 만든 다음 이를 교반하면서 석유계 기름을 투입하여 3-10분 정도 가동시켜 균일하게 혼합시킨다. 이렇게 혼합된 일차 혼합물은 1-2일간 상온에서 정치시킨다.To mix petroleum oil and animal oil, first, animal oil such as pork or tallow in semi-solid state is heated and made into liquid state, and then mixed with petroleum oil while stirring for 3-10 minutes. The primary mixture thus mixed is allowed to stand at room temperature for 1-2 days.

한편, 가축의 배설물은 축사바닥으로부터 자동적으로 오줌이 제거되도록 경사지게 설계하여 얻어진 고형 배설물을 가능한한 최대로 건조시켜 냄새가 발생하는 인자를 제거하고, 분쇄기를 사용하여 분말로 가공한다.On the other hand, animal wastes are designed to be inclined so that urine is automatically removed from the bottom of the barn, and the solid wastes obtained by drying them as much as possible to remove the odor-producing factor and processed into powder using a grinder.

그후 기름 혼합물과 가축의 배설물 분말을 중량비로 1 : 2.5-3의 비율로 반죽하여(S2), 가압 스크류를 이용하여 일정한 직경의 봉형상으로 압출하면서 일정한 크기로 컷팅하여 건조시키면 본 발명의 고체연료가 얻어진다(S3,S4).Thereafter, the oil mixture and the animal waste powder are kneaded at a weight ratio of 1: 2.5-3 (S2), and are cut and dried to a constant size while extruding into a rod of a constant diameter using a pressure screw to dry the solid fuel of the present invention. Is obtained (S3, S4).

이 경우 일차 혼합물과 가축의 배설물 분말을 중량비로 1 : 2.5 이하의 비율로 반죽하면 반죽된 이차 혼합물이 너무 묽어서 가압 스크류에서 봉형상으로 성형이 안되며, 1 : 3 이상의 비율로 반죽하면 이차 혼합물이 반죽이 잘되지 않거나 너무 딱딱하여 압출 성형성과 컷팅 작업성이 나빠진다.In this case, if the primary mixture and animal waste powder are kneaded at a weight ratio of less than 1: 2.5, the kneaded secondary mixture is too thin to form into rods with a pressure screw. The dough is not good or too hard, which leads to poor extrusion and cutting workability.

(실시예)(Example)

우지 10Kg을 가열하여 액체상태로 만든 다음 이를 교반하면서 경유 1Kg을 투입하여 3-10분 정도 가동시켜 균일하게 혼합한후, 혼합된 일차 혼합물을 2일간 상온에서 정치시키고, 숙성된 일차 혼합물에 미리 준비한 가축의 배설물 분말 30Kg을 혼합하여 반죽하였다. 그후 반죽된 이차 혼합물을 가압 스크류에서 봉형상으로 압출하면서 일정한 크기로 컷팅하여 얻어진 펠렛을 건조시켜 고체연료를 얻는다.10 kg of tallow is heated to a liquid state, and 1 kg of light oil is added thereto while stirring to operate for about 3 to 10 minutes to uniformly mix, and then the mixed primary mixture is allowed to stand at room temperature for 2 days and prepared in advance in the mature primary mixture. 30 Kg of livestock manure powder was mixed and kneaded. The pellet obtained is then cut to a constant size while extruding the kneaded secondary mixture in a rod form from a pressure screw to dry the pellets to obtain a solid fuel.

상기한 고체연료는 불꽃 테스트 결과 파란 불꽃이 나타나면서 연소되어 화력이 우수한 것으로 나타났고, 연소시에 가축 배설물에서 나는 냄새는 전혀 나지 않았다.The solid fuel was burned with a blue flame as a result of a flame test, and showed excellent thermal power, and there was no smell from animal waste during combustion.

상기한 바와같이 본 발명에서는 값싼 동물성 기름과 인화성이 높은 석유계 기름을 혼합시킴에 의해 발화시의 인화성을 높이며, 여기에 매우 값싼 가축의 배설물을 건조시켜 분쇄한 분말을 혼합하여 일정한 크기로 성형함에 의해 축산 오물을 환경 친화적으로 처리가 가능하며 이로부터 얻어지는 고체연료는 저비용 높은 인화성을 갖는 새로운 에너지원으로 사용이 가능하다.As described above, in the present invention, by mixing a cheap animal oil and a highly flammable petroleum-based oil to increase the flammability at the time of ignition, to dry the excrement of very cheap livestock to form a predetermined size by mixing the pulverized powder This makes it possible to treat livestock wastes in an environmentally friendly way, and the solid fuel obtained therefrom can be used as a new energy source with low cost and high flammability.

이상에서는 본 발명을 특정의 바람직한 실시예를 예를들어 도시하고 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 가능할 것이다.In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
