Abstract
본 발명은 선별분리 과정을 거치지 않고 무작정 투입하여 매립한 쓰레기를 성상별로 재구별하여 매립장을 재활용하기 위한 방안에 관한 것이다.The present invention relates to a method for recycling landfills by reclassifying wastes buried by randomly inputting them without going through a screening process.
과거에는 각종 쓰레기를 성상별로 구별하여 매립하지 않고 무조건 매립장에 투기하는 바람에 매립장에는 재활용품을 비롯한 각종 쓰레기의 방치장이 되고 있다. 따라서 재활용이 가능한 쓰레기들이 방치되어 자원낭비를 심화시키고, 침출수 등으로 인한 환경오염이 극대화되고 있으며, 아울러 매립장의 공간을 비효율적으로 활용하는 문제점 등이 있었다.In the past, various types of garbage are not classified by land and are dumped at landfills, so landfills have become a dumping place for various wastes including recycled products. Accordingly, wastes that can be recycled are left unattended, intensifying waste of resources, maximizing environmental pollution due to leachate, etc., and inefficient use of space in landfills.
본 발명에 따른 매립 쓰레기의 선별분리시스템은 무분별하게 투기된 쓰레기를 재선별하여 분리함으로써, 재활용이 가능한 쓰레기는 재활용하고, 소각처리가 가능한 쓰레기는 소각처리하도록 한다.In the landfill waste sorting and separating system according to the present invention, by re-selecting and separating the dumped garbage indiscriminately, the waste that can be recycled is recycled, and the waste that can be incinerated is incinerated.
이러한 공정을 거침으로써, 자원의 재활용이 가능하며, 선별분리후 발생하는 잔여공간을 활용하여 매립장 수명을 연장할 수 있으며, 환경오염을 방지하는 등의 장점을 기대할 수 있다.By going through these processes, resources can be recycled, and the life of the landfill can be extended by utilizing the remaining space generated after sorting and separation, and environmental pollution can be expected.
본 발명은 저렴한 가격으로 제작이 가능하며, 유지관리가 용이하고, 선별효율을 높인 매립장에 방치된 매립 쓰레기의 선별분리 시스템을 제공하는데 있다.The present invention is to provide a sorting and separation system of landfill waste, which can be manufactured at a low price, easy to maintain, and is left in a landfill site with improved sorting efficiency.
Description
[폐기물관리법]에 따르면, 산업폐기물(특정폐기물) 이외의 폐기물인 일반폐기물 중 분뇨를 제외한 것을 쓰레기라고 하고 있다. 여기서 산업폐기물이란 산업활동에 수반하여 발생하는 폐기물을 말하며, 일반 폐기물은 사람의 일상생활에 수반되어 발생하는 쓰레기·분뇨 등을 지칭한다(방사성 폐기물은 〈원자력법〉에 별도로 규정되었다) 쓰레기는 그 크기나 모양·성질에 따라 여러 가지로 분류할 수 있는데, 냉장고·텔레비전·세탁기 등의 폐가전제품과 책상·장롱 등의 폐가구류, 폐차·폐자전거 등과 같이 비정기적으로 배출되는 대형의 쓰레기가 있는 반면 일상적으로 배출되는 폐·휴지나 음식물 찌꺼기와 같은 쓰레기도 있다. 또 불연성 쓰레기·가연성 쓰레기로 분류할 수도 있으며, 소각시 유해가스를 발생하는 쓰레기나 토양·수질을 오염시키는 유해 쓰레기로도 나눌 수 있다. 이 중 가연성 쓰레기는 소각처리하는 것이 좋으며, 불연성 쓰레기와 유해가스를 발생하는 쓰레기는 매립 처리하고 수은전지나 형광등과 같이 중금속이 든 유해 쓰레기는 재활용하거나 안전매립하여야 한다.According to the Waste Management Act, general waste, which is waste other than industrial waste (specific waste), is excluded from manure. Herein, industrial waste refers to wastes generated by industrial activities, and general waste refers to wastes and manures generated by human daily life (radioactive wastes are separately defined in the Atomic Energy Act). It can be categorized into various types according to its shape and properties.In addition, there are large household wastes such as refrigerators, TVs and washing machines, and waste furniture such as desks and cabinets, and large-scale garbage that is discharged on a regular basis. There are also garbage, such as waste, waste paper and food waste, which are discharged on a daily basis. In addition, it can be classified as non-combustible waste or combustible waste, and it can be divided into garbage generating harmful gas when incinerated and hazardous waste polluting soil and water quality. Among them, combustible wastes should be incinerated, non-combustible wastes and wastes generating harmful gases should be landfilled, and hazardous wastes containing heavy metals such as mercury cells or fluorescent lamps should be recycled or safely landfilled.
최근에는 매립장에 쓰레기를 매립할 때 '폐기물관리법'을 준수하여 이루어지지만, 과거에는 쓰레기를 그 크기나 모양·성질에 따라 여러 가지로 분류하지 않고, 무작정 매립을 한 바 있다. 이러한 까닭으로 인하여, 냉장고·텔레비전·세탁기 등의 폐가전제품과 책상·장롱 등의 폐가구류, 폐차·폐자전거, 폐·휴지, 음식물 쓰레기등이 혼합되어 매립되었다.In recent years, when landfills are disposed of in landfills, they are in compliance with the Waste Management Act, but in the past, landfills have been randomly landfilled without sorting them according to their size, shape and properties. For this reason, waste household appliances such as refrigerators, TVs, and washing machines, and waste furniture such as desks and chests, waste cars, bicycles, wastes, waste papers, and food wastes were mixed and embedded.
이로인한 토양오염이 삼각하며, 유해가스 발생으로 인한 환경피해가 극심하였다. 또한 재활용 가능한 자원들이 매립되어 자원화의 기회를 잃음으로 인한 물적 손실도 극심하였다. 무작정 쓰레기를 매립하다 보니 매립장 활용이 효율적이지 못하여 매립장 공간이 금방 쓰레기 더미로 가득차 새로운 매립장을 건설하여야 하는 문제점 등이 있었다.Due to this, soil pollution was triangulated, and environmental damage caused by harmful gas was severe. In addition, the material loss caused by the reclaiming of recyclable resources and the loss of opportunities for resourceization were severe. As the landfill was unintentionally buried, the utilization of the landfill site was not efficient, and there was a problem in that a landfill site was filled with a pile of garbage and a new landfill site had to be constructed.
기존에 이러한 매립장 쓰레기들을 선별분리하는 각종 기계 및 기구 들이 개발되어 사용되고 있지만, 효과적인 운용 시스템이 개발되지 못해, 매립장 쓰레기의 선별분리 효율이 극대화되지 못하고 있었다.Conventionally, various kinds of machines and apparatuses for sorting and sorting out such landfill waste have been developed and used, but an effective operation system has not been developed, and the efficiency of sorting and separating landfill waste has not been maximized.
기존의 개별 기계에 의존한 매립쓰레기의 선별분리 기술로는 선별효율이 극대화되지 못함으로, 선별효율을 높이기 위해서는 효과적인 운용시스템이 필요한 것이다.As the sorting separation technology of landfill waste that is dependent on the existing individual machines does not maximize the sorting efficiency, an effective operation system is required to increase the sorting efficiency.
따라서 본 발명이 이루고자 하는 기술적 과제는 상술한 바와 같은 다양한 문제점들을 극복하여 저렴한 가격으로 제작이 가능하며, 유지관리가 용이하고, 선별효율을 높인 극대화시킨 매립쓰레기의 선별분리 시스템을 제공하는데 있다.Therefore, the technical problem to be achieved by the present invention is to provide a sorting separation system of landfill waste that can be produced at a low price by overcoming the various problems as described above, easy to maintain, and improved sorting efficiency.
기존의 선별이 어려웠던 "금속류, 플라스틱류, 종이류, 유리류, 토사 및 골재류"도 효과적으로 선별분리할 수 있는 방안을 제공함으로써, 매립쓰레기를 효과적으로 선별 분리함은 물론, 분리한 쓰레기의 재활용이 가능하며, 매립공간을 추가로 확보할 수 있는 잇점을 아울러 지니고 있다.By providing a method to effectively sort and separate "metals, plastics, papers, glass, earth and aggregates", which were difficult to sort out previously, the landfill waste can be effectively separated and recycled. It also has the advantage of securing additional landfill space.
본 발명에 따른 매립장에 매립된 쓰레기의 효과적인 선별분리 시스템을 구체적으로 설명하면 다음과 같다.Referring to the effective screening and separation system of the landfill in accordance with the present invention in detail as follows.
먼저 본 발명에 따른 매립쓰레기의 선별분리 시스템은 매립된 쓰레기를 굴착하여 컨베어로 이송하여 1차적으로 자석선별기를 통하여 철류를 선별하고 남은 잔류물을 복합스크린선별기로 이송하는 컨베어와, 이송된 쓰레기중 토사를 선별분리할 수 있는 복합스크린선별기와, 토사 선별분리후 남은 잔류물을 이송하는 컨베어와 이를 통하여 이송되어 온 잔류물중 골재를 선별하는 비중선별기와 선별하고 남은 부분을 이송하는 콘베어와, 이송되어온 잔류물중 비닐 및 가연성물질을 선별분리하는 라인으로 연결된다.First, the sorting and separating system of landfill waste according to the present invention excavates the landfilled waste and transports it to the conveyor. The conveyor first sorts iron through a magnetic sorter and transfers the remaining residues to the composite screen sorter. Composite screen sorter for sorting and separating soil, Conveyor for transporting residues after sorting and sedimentation, Specific gravity sorter for sorting aggregate from residues transported through it, Conveyor for sorting and transporting remaining parts It is connected by a line for separating and separating the vinyl and combustibles from the residue.
복합스크린 선별기를 통하여 토사류를 선별하고, 비중선별기를 통하여 골재류를 선별하여, 정밀하게 선별된 토사와 골재류는 복토재로 재활용하도록 한다.Soils are sorted through the composite screen sorter, and aggregates are sorted by the specific gravity sorter, and the precisely selected soils and aggregates are recycled as cover soil.
비닐 및 가연성 선별분리 라인을 통하여 선별분리된 비닐류와 가연성 물질들은 소각을 하거나, 재활용이 가능한 부분은 재활용을 하도록 한다.Vinyls and combustibles sorted through vinyl and combustible sorting lines are incinerated or recycled for recycling.
본 발명에 따른 내용을 보다 구체적으로 살펴 보면 다음과 같다.Looking at the content according to the invention in more detail as follows.
상기한 자석선별기는 자석의 자력을 활용하여 철류를 선별기에 부착시키는 방식으로, 철류를 선별하는 장치이다.The magnet sorter is a device for sorting the iron, by attaching the iron to the sorter by utilizing the magnetic force of the magnet.
상기한 복합스크린 선별기는 트롬멜스크린과 디스크스크린을 복합적으로 사용하는 것을 의미한다.The composite screen selector means using a trommel screen and a disk screen in combination.
트롬멜 스크린(Trommel Screen)이란 유입구를 통해 header로 유입된 쓰레기중 토사 및 골재는 head box 좌우의 둑을 넘어 드럼(DRUM) 내부면의 스크린(screen) 간극에 직교하게 흘러내려 하부로 빠져 나가며, 부피가 큰 물질들은 그 내부에 설치된 나선식배출판을 따라 유입구 반대편으로 서서히 배출함으로써, 유입된 쓰레기를 연속적으로 처리할 수 있는 설비를 의미한다.Trommel Screen (Trommel Screen) of the wastes and aggregates flowing into the header through the inlet flows over the banks on the left and right of the head box flows perpendicularly to the screen gap on the inner surface of the drum (DRUM) and exits to the bottom, Bulky material refers to a facility that can continuously dispose of incoming waste by slowly discharging it to the opposite side of the inlet along a spiral discharge plate installed therein.
디스크 스크린(Disk Screen)은 스크린을 지나는 유입물을 풍력에 의해 선별하는 장치를 의미한다.Disk Screen refers to a device that sorts by wind the inflow through the screen.
상기 비중 선별기는 물질의 비중을 활용하여 선별하는 장치로 골재류를 선별하는데 사용된다. 비중(比重, specific gravity)이란 각 물질의 질량이 그것과 같은 부피를 가진 표준물질의 질량의 몇 배인가를 나타낸 수치를 의미한다. 엄밀하게 질량은 일정 압력에서의 관성을 측정함으로써 결정되는데, 보통은 같은 장소에서의 무게비로 결정되므로 비중이라고 한다. 일반적으로 액체나 고체는 4℃의 물 1㎤ 1g으로 하고 이것을 표준으로 한다. 기체의 경우는 0℃, 1기압에서의 공기를 표준으로 취할 때가 많다. The specific gravity sorter is used to sort the aggregates as a device for selecting using the specific gravity of the material. Specific gravity is a measure of how many times the mass of each substance is the mass of a standard substance with the same volume. Strictly, mass is determined by measuring the inertia at constant pressure, which is usually called specific gravity because it is determined by the weight ratio in the same place. Generally, liquid or solid is 1 g of 1 cm 3 of 4 ° C water, and this is the standard. In the case of gas, air at 0 ° C and 1 atmosphere is often taken as a standard.
선별분리 공정이 끝난 잔류 쓰레기는 소각하고 재활용이 가능한 부분은 다시 재활용을 하도록 한다. 이러한 절차를 거칠 경우, 많은 양의 쓰레기가 재활용 및 소각 처리되므로 매립장 용적이 많이 넓어진다. 이공간 만큼을 매립용적이 증가되는 잇점을 지니고 있다.After the screening process, the remaining waste is incinerated and the parts that can be recycled are recycled again. This procedure results in a large amount of landfill volume, since a large amount of waste is recycled and incinerated. This space has the advantage of increasing landfill volume.
상술한 바와 같은 방법으로 매립쓰레기를 선별분리할 경우, 저렴한 가격으로 제조가 가능하며, 환경친화적이며 높은 경제성을 지닌 매립쓰레기의 선별분리 시스템을 구현할 수 있다.When the landfill waste is separated and sorted by the above-described method, the landfill waste can be manufactured at a low price, and an environment-friendly and high economical efficiency can be implemented.
본 발명에 따른 매립쓰레기의 선별 분리 시스템은 "금속류, 플라스틱류, 종이류, 토사 및 골재류"등의 선별분리를 통한 재활용이 가능하다.Separation and separation system of landfill waste according to the present invention can be recycled through the separation and separation, such as "metals, plastics, paper, earth and aggregate".
또한 선별분리를 통한 매립공간의 신규확보를 통하여 매립장 수명을 연장할 수 있는 장점을 아울러 지니고 있다.In addition, it has the advantage of extending the life of the landfill site by securing a new landfill space through screening separation.
