Description
본 발명은 도축시설에서 발생하는 유기성 폐기물을 이용한 바이오가스 및 이를 이용한 에너지 자립형 선진 축산 시스템에 관한 것이다.The present invention relates to biogas using organic wastes generated in slaughterhouses and an energy-independent advanced livestock farming system using the same.
근래에 들어 우리나라 국민들의 식생활 패턴이 서구화되면서 육류소비가 계속적으로 증가하고 있으며, 그에 발맞추어 전국의 도축시설에서 도살되는 가축의 두수 역시 매년 증가하고 있다. 현재 우리나라에는 소, 돼지, 닭 등의 식용가축들을 도살하는 도축시설이 약 100여 개 정도 운영되고 있는데, 이들 도축시설에서는 상당히 많은 량의 동물혈액, 체내 가축분뇨, 가축부산물, 슬러지 등을 포함한 유기성 폐기물이 발생하게 된다.In recent years, the consumption of meat has been steadily increasing with the westernization of the national diet patterns of Korean people, and the number of livestock slaughtered at national slaughter facilities is also increasing every year. Currently, there are about 100 slaughterhouses in Korea that slaughter cattle, pigs, chickens and other edible livestock, and these slaughterhouses have a considerable amount of animal blood, domestic livestock manure, livestock by-products, sludge, Waste will be generated.
한편 전 세계적으로도 도축시설에서 발생하는 유기성 폐기물의 처리문제는 점점 심각해지고 있는 형편이다. 현재 미국에는 약 6,200여 곳의 도축시설이 가동되고 있는데, 이 도축시설들에서 나오는 폐혈액의 거의 대부분 단순 폐기됨으로 인해 자원의 낭비 및 환경오염이 날로 심각해지고 있다. 그리고 동남아시아 각국들에서도 육류의 소비증가와 더불어 도축시설 및 도축 가축 수가 매년 증가하고 있기 때문에 도축과정에서 발생하는 이러한 유기성 폐기물의 처리문제가 더욱 심각한 문제로 대두되고 있다.On the other hand, the problem of disposal of organic wastes generated in slaughterhouses in the world is getting serious. Currently, there are about 6,200 slaughterhouses operating in the United States, and the waste of resources and environmental pollution are becoming serious due to the simple disposal of almost all of the blood from these slaughter facilities. In addition, in Southeast Asian countries, the problem of disposal of such organic wastes arising from the slaughter process is becoming more serious because of the increase in meat consumption and the increase of slaughter facilities and slaughtered cattle every year.
또한, 도축시설에서 발생하는 유기성 폐기물 중 폐혈액의 경우에는 감염성 폐기물로 분류되어 있어서 식약청의 관리 감독하에 폐기 처리되어야 하며, 정부로부터 정식으로 폐기물 처리업체로 허가받은 업체에서만 이러한 폐기물 처리 업무를 수행할 수 있도록 되어 있다. 이와 같이 엄격한 규제하에서 축산업자가 이러한 유기성 폐기물 처리를 위해 폐기물 처리업체에 지불해야 하는 비용이 만만치 않기 때문에 결과적으로 축산업의 원가구조에 상당한 부담으로 작용하고 있는 형편이다.Among the organic wastes generated from the slaughter facilities, the waste blood is classified as infectious waste and should be disposed of under the supervision of the KFDA. Only those companies which are authorized by the government as waste disposal companies shall perform such waste disposal duties . Under these strict regulations, the livestock industry has to pay the waste disposal company for the disposal of such organic wastes. As a result, it is a burden on the cost structure of the livestock industry.
그렇지만 도축시설에서 발생하는 동물혈액, 체내 가축분뇨, 가축부산물, 슬러지 등을 포함한 다량의 유기물을 함유한 폐기물은 혐기성 소화에 의해 바이오가스화 될 수 있다. 혐기성 소화공정을 통해 생성된 바이오가스는 대부분이 메탄(60~70%)과 이산화탄소(30~40%)로 이루어져 있다. 메탄은 보일러, 공조기, 또는 발전기를 통해 열 에너지, 냉각 에너지 및 전기 에너지로 전환하여 사용한다. 도축시설에서는 소모되는 전력 연료비가 총 경비의 대부분을 차지하고 있으며, 도축공정 중 탕박공정, 도체냉각공정이 대표적인 에너지 다소비 공정이다. 따라서 도축시설에서 발생하는 유기성 폐기물로부터 바이오가스를 생성하여 도축시설에 이용하면, 유기성 폐기물 처리 문제를 극복할 수 있을 뿐만 아니라 에너지 효율을 향상시킬 수 있다.However, wastes containing large amounts of organic matter, including animal blood, livestock manure, livestock by-products, and sludge, generated in slaughterhouses can be biogasized by anaerobic digestion. Most of the biogas produced by the anaerobic digestion process consists of methane (60 ~ 70%) and carbon dioxide (30 ~ 40%). Methane is converted to thermal energy, cooling energy and electrical energy through boilers, air conditioners, or generators. In the slaughterhouse, the electricity cost consumed is the most part of the total cost. In the slaughtering process, the boiling process and the conductor cooling process are typical energy consumption processes. Therefore, biogas generated from organic wastes generated from slaughterhouses can be used in slaughterhouses to overcome organic waste disposal problems and improve energy efficiency.
또한, 종래에는 바이오가스에 포함된 30~40%의 이산화탄소는 자원화가 가능함에도 불구하고 불순물로 인식하여 전량 배출하였다. 이산화탄소는 산업용 또는 농업용으로 사용될 수 있으며, 예를 들면 조선소 등에서 용접 목적으로 또는 하우스 시설 등에서 농작물의 품질 및 생산량 증대 목적으로 사용될 수 있다. 본 기술에서는 바이오가스로부터 이산화탄소를 분리하여 이산화탄소 실신시스템에 사용하고자 한다.In the past, 30-40% of the carbon dioxide contained in the biogas was recognized as an impurity although it was able to be recycled, and the entire amount was discharged. Carbon dioxide can be used for industrial or agricultural use, for example, in a shipyard or the like, for welding purposes, or in a house facility, for the purpose of increasing the quality and production of crops. In this technology, carbon dioxide is separated from biogas to be used in carbon dioxide syncope system.
종래 사용되던 전기실신 방법은 스트레스가 많이 발생해서 고기 품질이 저하되는 반면, 이산화탄소 실신시스템은 일정수준의 이산화탄소 농도를 유지하고 있는 밀폐된 방에 일정 시간동안 통과시킴으로써 스트레스 없이 자연스럽게 실신시킴으로써 인도적이며, 골격의 파손, 고기조직내 출혈 방지, 물퇘지고기(pale, soft, exudative, PSE육)의 출현율을 감소하는 효과가 있어 고기품질이 향상되어 보다 육질이 좋다.The conventional electrophysiological method used is humanistic because it causes a lot of stress and deteriorates meat quality, while the carbon dioxide syncope system passes through a closed room maintaining a certain level of carbon dioxide concentration for a certain time, (Pale, soft, exudative, PSE meat), and meat quality is improved and meat quality is better.
따라서 도축시설에서 발생하는 유기성 폐기물을 처리하고 자원화하여 도축시설의 선진화와 에너지 자립화를 위한 시스템의 개발이 시급한 실정이다.Therefore, it is urgent to develop a system for advanced slaughtering facilities and energy independence by treating and recycling organic wastes generated from slaughter facilities.
종래 기술로서, 한국공개특허 제10-2010-0028413호에는 음식물쓰레기, 도축폐수, 하수슬러지, 매립지 침출수와 같은 고농도 유기성 폐수를 혐기성 소화설비에 유입하여 폐수에 포함된 유기물을 분해하고, 상기 혐기성 소화설비를 거친 소화여액을 고도처리설비로 유입하여 질소 및 인을 제거하며, 상기 혐기성 소화설비에서 발생한 메탄가스는 가스저장설비로 회수하여 에너지화함에 있어서, 상기 혐기성 소화설비 및 고도처리설비에서 발생한 슬러지를 슬러지 저장조로 회수하여 가용화장치로 가용화한 후, 상기 가용화한 슬러지를 혐기성 소화설비로 유입함과 아울러 상기 가용화한 슬러지를 고도처리설비의 반응조에 선택적으로 공급함으로써, 혐기성 소화설비의 메탄가스 발생량을 증진하여 폐수의 에너지화를 극대화할 수 있도록 한 고농도 유기성 폐수의 처리방법을 개시하고 있다. 그러나, 상기 문헌의 경우에는 혈액을 포함한 도축폐수를 이용한다는 점만 동일할 뿐, 본 발명의 에너지 자립형 도축 시스템에는 이르지 못하고 있다.Korean Patent Laid-Open No. 10-2010-0028413 discloses that organic wastewater of high concentration such as food waste, slaughter wastewater, sewage sludge and landfill leachate is introduced into the anaerobic digestion plant to decompose the organic matter contained in the wastewater and the anaerobic digestion And the methane gas generated in the anaerobic digestion facility is recovered to the gas storage facility to be energized. In the anaerobic digestion facility and the sludge generated in the advanced treatment facility, The solubilized sludge is introduced into the anaerobic digestion facility and the solubilized sludge is selectively supplied to the reaction tank of the advanced treatment facility so that the amount of methane gas generated in the anaerobic digestion facility is reduced To maximize the energization of wastewater. It discloses a method of treatment. However, in the case of the above document, only the use of slaughter waste waters including blood is used, but the energy-independent slaughter system of the present invention is not achieved.
이에, 본 발명자들은 상기 문제점들을 극복하기 위해 연구하던 중, 도축시설에서 발생하는 유기성 폐기물을 혐기성 소화방법으로 분해 처리하여 바이오가스를 생성하고, 생성된 바이오가스를 에너지로 활용하여 다시 도축 시스템에 활용함으로써 에너지 자립형 축산 시스템을 구축할 수 있으며, 상기 에너지 자립형 축산 시스템은 유기성 폐기물을 이용하여 에너지 효율을 향상시킬 수 있음을 밝힘으로써 본 발명을 완성하였다.Accordingly, the inventors of the present invention, while studying to overcome the above problems, have proposed a method of decomposing organic wastes generated in a slaughterhouse by an anaerobic digestion method to generate biogas, utilizing the generated biogas as energy, The present invention has been accomplished by making it clear that the energy-independent type livestock system can be constructed and that the energy-independent type livestock system can improve the energy efficiency by using the organic waste.
본 발명의 목적은 도축시설에서는 다량의 유기성 폐기물이 발생하는데, 이를 처리하는데 많은 비용이 필요하며, 이는 자원화 가능함으로 축산업자뿐만 아니라 국가적으로 낭비이고, 현재 도축시설에서는 도축공정에 소모되는 전력연료비가 총 경비의 대부분을 차지하고 있으며, 도축공정 중 탕박공정, 도체냉각공정이 대표적인 에너지 다소비 공정이므로, 도축시설에서 발생하는 유기성 폐기물을 이용하여 바이오가스를 생산함으로써 에너지 자립형의 선진화된 도축시설을 구축하고 유기성 폐기물의 처리를 동시에 하고자 한다.It is an object of the present invention to provide a method of sowing a large amount of organic waste in an animal slaughterhouse, which requires a large amount of cost to process the slaughterhouse, which is a wasted country as well as a livestock industry, Since most of the total expenses are spent and the boiling process and the conduction cooling process are the typical energy consuming processes during the slaughtering process, an advanced energy-based slaughtering facility is constructed by producing biogas using organic waste generated from the slaughterhouse The organic wastes should be treated simultaneously.

바이오가스 플랜트는 정화 처리 공정을 포함하여, 유기성 폐기물이 박테리아에 의해 분해되어 액화, 산 생성 단계를 거친 뒤 바이오가스를 생산한다. 바이오가스는 혐기성 상태에서 생산되며, 이렇게 생산된 바이오가스는 메탄이 60~70%, 이산화탄소가 30~40%, 그리고 수분, 황 및 황화수소를 포함한 미량의 불순물을 포함하고 있다.Biogas plants, including the purification process, produce biogas after organic wastes are decomposed by bacteria and subjected to liquefaction and acid production. Biogas is produced in anaerobic conditions, and the biogas produced contains 60-70% methane, 30-40% carbon dioxide, and trace impurities including water, sulfur and hydrogen sulphide.
정제설비는 바이오가스 플랜트로부터 생산된 바이오가스로부터 이산화탄소 및 메탄가스를 제외한 수분, 황 및 황화수소를 포함하는 미량의 불순물을 제거하기 위한 설비이다. 정제설비에서 불순물이 제거된 바이오가스는 분리설비로 보내져 이산화탄소와 메탄가스를 분리하거나, 이산화탄소 실신시스템의 이산화탄소 수요가 없을시 또는 수요량을 초과할 시에는 일부 또는 전부가 열병합 발전기 또는 열흡수식 냉온수시스템으로 직접 공급될 수 있다.The purification facility is a facility for removing trace impurities including moisture, sulfur and hydrogen sulfide from biogas produced from a biogas plant except for carbon dioxide and methane gas.

By allowing the water to evaporate at 4 ° Celsius, the water evaporates and acts as a coolant that absorbs the surrounding heat (cooling energy) to produce cold water at about 7 ° Celsius. The evaporated water is absorbed by the absorbent, and the absorbed liquid, which is absorbed by the water, is heated by the heat source and separated again into the vapor refrigerant and absorbent. The separated refrigerant condenses and enters the cycle again. The heat absorption cold / hot water system can produce both cold water and hot water, and is switched to cold water production mode or hot water production mode depending on the production mode. In the production of hot water, hot water is supplied by heating the water by burning the gas supplied as a heat source (thermal energy). The process efficiency of the heat absorption cold / hot water system is 85 ~ 95% in the production of thermal energy and 90 ~ 110% in the production of cooling energy. The heat energy thus produced is used for the boiling process, and the cooling energy is used for the conductor cooling process.
