Description
본 발명은 종량제 및 분리수거가 활성화되면서 전체 쓰레기중 점차 차지하는 비중이 증가하고 있는 음식물 쓰레기를 발생단계에서 최대한 감량화하면서, 호기성 미생물에 의하여 작물 등의 경작 재배에 유효한 농지환원용 유기퇴비로 만드는 퇴비화 장치에 관한 것으로 특히 2차적 환경오염인 악취발생을 예방할 수 있으며 발생열을 재이용하는 에너지 효율이 우수한 음식물쓰레기의 퇴비화 장치에 관한 것이다.The present invention is a composting device that makes the organic compost for farmland reduction effective for cultivation of crops by aerobic microorganisms while reducing the amount of food waste, which is gradually increasing the proportion of the total waste as the total amount of waste and the separate collection is activated at the generation stage, In particular, the present invention relates to a composting device of food waste having excellent energy efficiency, which can prevent the occurrence of odor, which is a secondary environmental pollution, and reuse the generated heat.
최근 생활수준의 향상과 문화수준의 향상으로 인하여 각 방면에서 발생되는 폐기물에 많은 변화를 보이고 있다. 그 중에서 1991년도부터 활성화되기 시작한 쓰레기 분리수거제도에 의하여 재활용품과 재활용이 불가능한 쓰레기를 분리하기 시작하였으며, 1995년도부터 실시된 종량제는 쓰레기가 경제적 부담으로 연계되면서 배출되는 쓰레기 속에서 유기물을 분리 수거하는 제도가 더욱 더 촉진되었다.Recently, due to the improvement of living standards and cultural standards, there are many changes in the wastes generated in each area. Among them, the waste collection system, which has been activated since 1991, began to separate recyclables and non-recyclable wastes.In 1995, the pay-as-you-go system separates and collects organic matters from the wastes generated as waste is linked to economic burden. Was promoted even more.
이러한 움직임에 의하여 쓰레기의 양을 줄임과 동시에 자원의 재활용이라는 측면에서 일석이조의 효과를 보고 있다.By this movement, we are seeing the effect of trillion people in terms of reducing waste and recycling resources.
유용한 자원이 발생단계에서 분리 수거되어 재활용되면서 쓰레기의 질에 큰 영향을 주어 상대적으로 음식물 쓰레기가 차지하는 비율이 증가하는 현상이 나타나고 있다. 사업장 및 가정의 생활쓰레기가 전체 쓰레기 중에 차지하는 양이 환경부의 통계로는 약 26∼28% 수준이며, 실제 생활쓰레기중의 음식물쓰레기에 대한 조사에서는 50%선까지 나타나는 것으로 보고되고 있다. 이전에는 수분함량이 크게 문제되지 않았으나 최근에는 상대적으로 음식물 쓰레기에 의하여 전체 수분함량이 증가하는 현상이 관찰되고 있다. 쓰레기중의 높은 수분함량은 소각처리에 있어서 발열량을 저하시켜, 보조연료 사용량을 증가시키고 있으며, 매립시에는 악취 및 침출수의 발생 등의 많은 문제점을 야기시키고 있다.As useful resources are collected and recycled at the generation stage, the quality of garbage is greatly affected and the proportion of food waste is relatively increasing. According to the Ministry of Environment's statistics, the amount of household and household waste in the household waste is about 26 to 28%, and it is reported that up to 50% of the household waste is surveyed. Previously, the water content was not a big problem, but recently, a phenomenon in which the total water content is relatively increased due to food waste has been observed. The high moisture content in the waste lowers the calorific value in the incineration treatment, thereby increasing the amount of auxiliary fuel used, and causes many problems such as the generation of odor and leachate during landfilling.
최근에는 발생단계에서 수분함량을 50%이하로 유지시키는 감량화조치가 발효되어 규제되고 있는 실정이다. 실제적으로 수분함량을 50%로 유지하기 위해서는 탈수로는 불가능하고 건조 및 발효를 시켜야 가능하다. 최근에 건조 및 건조발효라는 명목으로 많은 감량화장치가 보급되어 있으나, 대부분의 감량화 장치가 기계적인 결함으로 인하여 정상 운전이 되지 못하여 사회적으로 많은 논란의 대상이 되고 있다. 특히 건조발효장치에서는 발효라는 용어를 사용하고 있으나, 대부분이 건조에 치중하고 있는 것이 현실이다. 이들은 적당한 열과 산소의 공급이 골고루 이루어지지 않아 발효기간이 길고 분해율이 떨어지며 전체적으로 균일한 발효가 이루어지지 않는 단점이 있다. 생성된 물질을 퇴비나 사료로 사용할 수 있다고는 하나, 실제적으로는 어디에도 사용하지 못하는 상태로 배출되고 있는 실정이다.Recently, reduction measures to keep the water content below 50% at the development stage has been in effect and regulated. In practice, dehydration is not possible to maintain the water content at 50%, and drying and fermentation are possible. Recently, many reduction devices have been popularized in the name of drying and drying fermentation, but most of the reduction devices cannot be operated normally due to mechanical defects, and thus have been the subject of much controversy in society. In particular, the term "fermentation" is used in a dry fermentation apparatus, but most of them focus on drying. They have the disadvantage that the proper heat and oxygen supply is not evenly made, the fermentation period is long, the decomposition rate is lowered, and the uniform fermentation is not made overall. Although the produced material can be used as compost or feed, it is being discharged in a state where it is not actually used anywhere.
이러한 감량화장치들의 단점은 건조와 발효를 한 반응조에서 행하므로 미생물을 활성화시키는 것이 불가능하고, 미생물이 유기물을 분해 하는데 필요한 충분한 시간을 주지 않아 발효효율이 떨어져 건조에 머물고 만다. 대부분의 장치가 발효와 건조에 대한 기본적인 개념이 없이 제작되어 발효와 건조의 성격이 명확하지 않은 상태이다.The disadvantages of these reduction devices are that it is impossible to activate microorganisms because they are carried out in a reactor that has been dried and fermented, and the microorganisms do not give enough time to decompose organic matters so that the fermentation efficiency remains low. Most of the devices are manufactured without the basic concept of fermentation and drying, so the nature of fermentation and drying is not clear.
또한, 원통의 내부에 격판을 설치하여 건조단과 발효단을 분리 구성한 것도 있으나 이는 건조단과 발효단을 각각 구동시키기가 어려워 최적의 운전을 위해서는 다소 비효율적인 면이 있었다.In addition, there is a separate structure of the drying stage and the fermentation stage by installing a diaphragm inside the cylinder, which is difficult to drive the drying stage and fermentation stage, respectively, there was a somewhat inefficient side for optimal operation.
본 발명은 상기와 같은 문제점을 해결하기 위하여 건조단 유입부에 파쇄기를 설치하여 갈비뼈등 이물질의 투입으로 인한 기기의 고장을 억제하고, 건조단과 발효단을 명확하게 분리하여 초기단계에서 발효에 적합한 수분함량까지 회수열을 이용하여 건조하고, 건조된 음식물쓰레기를 발효단으로 이송하여 미생물에 의하여 호기성상태에서 음식물 쓰레기를 분해하기 위한 것으로, 건조단은 교반자에 의한 중앙구동으로 하고 발효단은 드럼회전에 의한 주변구동형으로 하여 이를 모터에 의해 구동되게 하고 건조단 하부와 발효단 중앙부를 이송스크류에 의하여 음식물쓰레기를 건조단에서 발효단으로 이송시키며, 발효단에서 발효된 퇴비를 배출할 때 발효단 회전체 중앙의 배출스크류에 의해 배출구로 배출되게 하며, 이때 발생되는 가스를 미세분진제거 및 수분분리설비를 이용하여 미립자, 수분을 분리제거하고 악취물질은 탈취탑에서 제거한 다음 고온의 공기를 건조단으로 이송하여 건조열원으로 발생폐열을 재활용하므로서 에너지효율증대, 처리시간의 단축, 설치장소의 최소화와 설비비 및 유지관리비의 절감은 물론 배출가스 등에 의한 2차적 환경오염을 예방할 수 있는 음식물쓰레기의 퇴비화 장치를 제공하기 위한 것이다.In order to solve the problems described above, the present invention provides a crusher at the inlet of the drying stage to suppress the failure of the device due to the introduction of foreign substances such as ribs, and clearly separates the drying stage and the fermentation stage, so that moisture suitable for fermentation in the initial stage is provided. It is dried by using recovery heat to the contents, and the dried food waste is transferred to the fermentation stage to decompose food waste in aerobic state by microorganisms. The drying stage is a central drive by agitator and the fermentation stage is drum rotation. Peripheral drive type is driven by a motor, and the lower part of the drying stage and the center of the fermentation stage are transported food waste from the drying stage to the fermentation stage by a transfer screw, and the fermentation stage is discharged when the fermentation stage is discharged. By the discharge screw in the center of the rotating body The gas generated at this time is removed by fine dust removal and water separation equipment, and fine particles and water are separated and odorous substances are removed from the deodorization tower, and high temperature air is transferred to the drying stage to generate waste heat. The purpose of the present invention is to provide a composting device for food waste that can prevent secondary pollution due to emissions, as well as increase energy efficiency, shorten processing time, minimize installation sites, and reduce equipment and maintenance costs.

이렇게 건조단(1)으로 공급된 음식물 쓰레기는 자체 폐열 즉, 탈취 폐열에 의해 간조단(1) 내에서 온도가 60∼70℃정도로 유지되며 건조단(1) 내에서 교반자(4)에 의해 교반되면서 건조되어 함수율이 60∼70%로 되는 것이다.The food waste supplied to the drying stage 1 is maintained at a temperature of about 60 to 70 ° C. in the low tide stage 1 by its own waste heat, that is, deodorization waste heat, and is stirred by the agitator 4 in the drying stage 1. It is dried while stirring, and the water content will be 60 to 70%.
이와 같이 음식물쓰레기가 건조되면 건조단(1) 하부의 이송스크류부(12)가 모터(9)에 의해 구동되고, 건조된 음식물쓰레기는 이송스크류부(12)의 스크류에 의해 이송되어 투입구(16)를 통해 발효단(2)으로 투입되는 것이다.When the food waste is dried in this way, the transport screw 12 of the lower end of the drying stage 1 is driven by the motor 9, and the dried food waste is transported by the screw of the transport screw 12 to be inserted into the inlet 16. It is injected into the fermentation stage (2).
발효단(2)으로 투입된 건조된 음식물쓰레기는 발효단(2) 차체의 회전과 발효단(2) 내부벽면에 형성되어 있는 배플(26)에 의해 먼저 발효된 음식물쓰레기와 함께 교반되어 퇴비화가 진행되는 것이다.The dried food waste introduced into the fermentation stage 2 is stirred with the food waste fermented first by the rotation of the fermentation stage 2 and the baffle 26 formed on the inner wall of the fermentation stage 2 to compost. Will be.
여기서 발효단(2) 내부를 호기성상태를 유지시키기 위하여 공기공급브로워(25)를 이용 흡기관(14)을 통해 발효단(2) 내부로 깨끗한 공기를 공급하는 것이다. 이때 공급되는 공기의 량을 0.5ℓ/min.Kg-Solid 정도가 된다.In order to maintain the aerobic state inside the fermentation stage (2) is to supply clean air into the fermentation stage (2) through the intake pipe (14) using the air supply blower (25). At this time, the amount of air supplied is about 0.5ℓ / min.Kg-Solid.
이와 같이 새로운 공기 공급에 의해 발효단(2) 내부가 호기성상태로 유지되며 발효된 음식물쓰레기와 새로 투입된 건조된 음식물쓰레기가 발효단(2)의 자체 회전으로 배플(26)에 의해 교반되면서 미생물 자체 발열에 의해 발효 적정온도인 50∼60℃를 유지되며 이러한 과정을 통해 음식물쓰레기가 발효되어 최종적으로 퇴비화 되는 것으로 이때 퇴비화된 음식물쓰레기의 함수율은 35∼45% 정도가 된다.As such, the inside of the fermentation stage 2 is maintained in an aerobic state by the supply of new air, and the fermented food waste and the newly-dried dried food waste are stirred by the baffle 26 by the self-rotation of the fermentation stage 2 and the microorganisms themselves. The fermentation temperature is maintained at 50 ~ 60 ℃ by the exotherm and through this process, food waste is fermented and finally composted. At this time, the moisture content of the composted food waste is about 35 to 45%.
이와 같이 발효가 완료된 음식물쓰레기, 즉 퇴비를 배출할 때 발효단(2)의 회전이 정상적으로 연속 가동되면서,As the fermentation stage 2 is rotated normally when the food waste, which is fermentation is completed, that is, compost is discharged normally,
발효단(2)의 배출스크류부(13)가 모터(20)에 의해 구동되어 퇴비를 인입구(17)를 통해 배출스크류부(13)의 스크류에 의해 배출구(18)로 배출되는 것이다. 여기서 인입구(17)가 발효단(2)의 중심위쪽에 있어 항상 발효단(2) 내에는 발효된 음식물쓰레기가 남아 있게 되어 항상 호기성상태를 유지하게 되고 새로 투입되는 건조 음식물쓰레기의 발효를 촉진시켜 그 발효 효율을 높일 수가 있는 것이다.The discharge screw 13 of the fermentation stage 2 is driven by the motor 20 to discharge the compost to the discharge port 18 by the screw of the discharge screw 13 through the inlet 17. Here, the inlet 17 is located above the center of the fermentation stage 2 so that the fermented food waste remains in the fermentation stage 2 at all times to maintain the aerobic state and to promote the fermentation of newly introduced dry food waste. The fermentation efficiency can be improved.
이상과 같은 일년의 과정을 반복 시행하는 것이다.Repeat this year-long process.
본 발명 장치에 의해 건조 및 발효시 발생되는 수증기 및 가스는 배출브로워(22)에 의해 강제적으로 건조단(1)과 발효단(2)의 배기관(11)(15)을 통하여 배기되며, 배기 가스는 미세분진제거 및 수분제거설비(21)를 통과하면서 미세분진 및 수분이 제거되어 하부로 배출되며 공기는 미세분진 및 수분이 제거된 가스는 미세분진제거 및 수분제거설비(21) 상부로 배출되어 배출브로워(22)를 통하여 열교환기(23)에서 예열된후 탈취탑(24)에서 최종적으로 탈취된다. 본 발명의 미세분진제거 및 수분제거설비(21)는 물리적인 방법을 사용하였고 탈취탑(24)은 백금촉매 탈취탑(24)을 사용하였다.Water vapor and gas generated during drying and fermentation by the apparatus of the present invention are forcibly exhausted by the exhaust blower 22 through the exhaust pipes 11 and 15 of the drying stage 1 and the fermentation stage 2, and the exhaust gas. The fine dust and water is removed while passing through the fine dust removal and water removal equipment 21 is discharged to the bottom, the air is fine dust and water removed gas is discharged to the top of the fine dust removal and water removal equipment 21 After being preheated in the heat exchanger 23 through the discharge blower 22, it is finally deodorized in the deodorization tower 24. The fine dust removal and water removal equipment 21 of the present invention used a physical method and the deodorization tower 24 used a platinum catalyst deodorization tower 24.
탈취탑(24)을 통과한 깨끗한 고온의 공기는 건조단(1)의 흡기관(10)으로 반송되어 건조단(1)의 건조열원으로 재활용되며 잉여 가스는 열교환기(23)를 거쳐 냉각되어 대기중으로 배출된다.The clean hot air passing through the deodorization tower 24 is returned to the intake pipe 10 of the drying stage 1 and recycled to the drying heat source of the drying stage 1, and the surplus gas is cooled through the heat exchanger 23. Emissions to the atmosphere.
여기서 흡기관(10)으로 보내지는 공기와 배출되는 공기비는 6:4 정도이다.Here, the ratio of the air sent to the intake pipe 10 and the discharged air is about 6: 4.
한편 건조단(1) 및 발효단(2)에서 배출되는 수증기를 포함한 배기가스중 미세분진질제거 및 수분제거설비(21)를 통해 제거된 수분은 플로트트랩에 모아져 일정량이 되면 자동으로 배출된다.Meanwhile, the moisture removed through the fine dust removal and water removal facilities 21 in the exhaust gas including the steam discharged from the drying stage 1 and the fermentation stage 2 is collected in a float trap and automatically discharged when a predetermined amount.
이와 같이 건조단(1)에서 발생되는 배기가스는 수분을 제거 및 탈취탑(24)에서의 악취제거후 고온상태로 건조단(1)으로 이송되므로 음식물쓰레기의 건조를 위하여 별도의 열풍설비가 필요 없으며 배기가스중 악취를 유발하는 가스상물질을 제거하여 대기중으로 배출하므로 건조시 발생되는 악취 등의 가스로 인한 2차적인 환경오염을 예방할 수 있는 것이다.As such, the exhaust gas generated in the drying stage 1 is transferred to the drying stage 1 at a high temperature after removing moisture and removing odor from the deodorizing tower 24, so that a separate hot air facility is required for drying food waste. In addition, it removes gaseous substances causing odor from exhaust gas and releases them to the atmosphere, thereby preventing secondary environmental pollution caused by odorous gases generated during drying.
이와 같이 음식물쓰레기는 연속적으로 진행되면서 건조에 의하여 수분이 제거되며 미생물에 의하여 발효 분해되어 80∼90%정도의 높은 감량화율이 얻어지며 생성된 물질은 퇴비로서 사용이 가능하게 되는 것이다.As such, the food waste is continuously removed, and the moisture is removed by drying. The food waste is fermented and decomposed by microorganisms to obtain a high reduction ratio of about 80 to 90%, and the produced material is used as compost.
이상과 같이 본 발명의 음식물 쓰레기 퇴비화 장치는 음식물 쓰레기의 처리단계를 건조와 발효단계로 명확하게 분리하여 건조물을 호기성 미생물에 의하여 발효 분해시킴으로서 감량화율을 높였으며, 또한 생성물을 유용한 퇴비로 활용하므로서 음식물 쓰레기로 인한 환경오염을 예방할 수 있음은 물론 처리시간의 단축, 설치장소의 최소화, 설비비 및 유지관리비의 절감등 경제성이 높아 저비용 고효율로 퇴비화 시킬 수 있으며 배출가스를 완전하게 처리하므로 그로 인한 2차적인 환경오염을 예방할 수 있는 효과가 있는 것이다.As described above, the food waste composting device of the present invention clearly separates the processing step of the food waste into drying and fermentation stages, thereby increasing the reduction rate by fermenting and decomposing the dry matter by aerobic microorganisms, and by using the product as a useful compost. It is not only able to prevent environmental pollution due to waste, but also to reduce the processing time, minimize the installation place, and reduce the cost of equipment and maintenance, so it can be composted with low cost and high efficiency. It is effective to prevent environmental pollution.
