효율적인 폐기물 선별방법{Efficient waste sorting method}Efficient waste sorting method

본 발명은 일차적으로 자력선별에 의해 철금속류가 분리된 후 파쇄기에서 분쇄되어 건조기에서 열풍에 의해 경량물(종이, 비닐 등)이 분리된 생활폐기물 및 산업폐기물 중에서 유기성분류, 폐합성 고분자 화합물류, 비철금속류, 초자기류를 종류별로 세밀하게 분리하는 효율적인 폐기물 선별방법에 관한 것이다.The present invention primarily relates to organic components, waste synthetic polymer compounds, from household and industrial wastes from which ferrous metals are separated by magnetic sorting, then crushed in a crusher, and light weights (paper, vinyl, etc.) are separated by hot air in a dryer; It relates to an efficient waste sorting method that finely separates non-ferrous metals and glazes by type.

종래의 폐기물 선별방법은 폐기물 수거차량에 의해 수거된, 봉지에 담긴 폐기물을, 저장실에 투입하여 저장실에 저장하였다가 크레인과 같은 투입기로 파봉하면서 선별장치에 투입되는 폐기물을 사람과 자력선별기에 의해 재활용될 수 있는 철금속류, 비철금속류, 초자기류, 비닐, 종이류, 폐합성 고분자 화합물류 및 유기성분류로 선별하였다.In the conventional waste sorting method, the waste in bags collected by the waste collection vehicle is put into a storage room, stored in the storage room, and then the waste input to the sorting device is recycled by a person and a magnetic sorter while breaking it with an inserter such as a crane. Possible ferrous metals, non-ferrous metals, porcelain, vinyl, paper, waste synthetic polymer compounds and organic components were selected.

상기와 같은 종래의 폐기물 선별방법은 사람이 육안으로 확인하여 수작업으로 분리하였기 때문에 작업능률이 낮으며, 특히 먼지와 악취가 많은 작업환경으로 인하여 장시간 작업이 곤란하게 되었다.In the conventional waste sorting method as described above, work efficiency is low because a person manually separates the waste with the naked eye, and in particular, it is difficult to work for a long time due to a work environment with a lot of dust and odors.

상기 종래의 폐기물 선별방법의 단점을 해결하기 위해, 폐기물 수거차량에 의해 수거된, 봉지에 담긴 폐기물을, 저장실에 저장하였다가 크레인과 같은 투입기로 파봉하면서 선별장치에 투입되는 폐기물을 자력선별기에 의해 철금속을 선별시킨 뒤에 탈수 또는 건조시킨 후 풍력 선별하여 비닐, 종이류를 선별하고, 그 다음 진동 선별하여 비철금속을 선별하고, 풍력에 의해 초자기류를 선별할 수 있는 선별방법이 개발되었다.In order to solve the disadvantages of the conventional waste sorting method, the waste in bags collected by the waste collection vehicle is stored in a storage room, and the waste that is put into the sorting device while breaking it with an inserter such as a crane is separated by a magnetic sorter. After sorting ferrous metals, dehydration or drying, wind sorting to sort vinyl and paper, then vibration sorting to sort non-ferrous metals, and a sorting method that can sort super magnetic fluxes by wind power has been developed.

하지만, 상기 개발된 종래의 선별방법은 전처리 공정에서 단지 파쇄처리 및 건조처리만 수행된 폐기물을 비중에 의하여 선별하는 것이어서, 파쇄된 형상크기에 따라 그 중량을 달리하는 비철금속류, 초자기류 및 폐합성 고분자 화합물류와 그리고 함수율에 따라 그 중량을 달리하는 유기성분류(음식물 등)을 세밀하게 선별할 수 없어서, 비철금속류, 초자기류 및 폐합성 고분자 화합물류는 재활용되기에 부적합하게 되었고, 유기성분류를 폐기물 고형연료나 건조사료로 만들 경우에 원하는 품질을 얻을 수 없었고, 유기성분류를 소각처리시 폐합성 고분자 화합물류가 상기 유기성분류에 함유되어 대기를 오염시켰다.However, the conventional sorting method developed above is to sort wastes that have only been subjected to crushing and drying in the pretreatment process by specific gravity, so that the weight of non-ferrous metals, glassware, and waste synthesis varies according to the size of the crushed shape. Because it was not possible to precisely select polymer compounds and organic components (foods, etc.) whose weight differs depending on the moisture content, non-ferrous metals, ultra-porcelain and waste synthetic polymer compounds became unsuitable for recycling, and organic components were disposed of as waste. In the case of solid fuel or dry feed, the desired quality could not be obtained, and when the organic components were incinerated, waste synthetic polymer compounds were contained in the organic components and polluted the air.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 전처리 공정에서 철금속과 가연성 폐기물인 폐비닐, 폐지류가 선별 제거되어 건조된 산업 및 생활 폐기물 중에서, 유기성분류, 비철금속류, 초자기류, 폐합성 고분자 화합물류 등을 세밀하게 선별할 수 있는 효율적인 폐기물 선별방법을 제공하는 것을 목적으로 하고 있다.Therefore, the present invention has been devised to solve the above problems, and among industrial and household wastes dried by selectively removing ferrous metals and combustible wastes such as waste vinyl and waste paper in the pretreatment process, organic components, non-ferrous metals, An object of the present invention is to provide an efficient waste sorting method that can finely select porcelain and waste synthetic polymer compounds.

상기한 바와 같은 본 발명은 전처리 공정에서 철금속과 가연성 폐기물인 폐비닐, 폐지류가 선별 제거되어 건조된 산업 및 생활 폐기물중에서, 유기성분류, 비철금속, 초자기류, 폐합성 고분자 화합물류 등을 세밀하게 선별할 수 있는 선별방법을 제공하여, 비철금속, 초자기류 및 폐합성 고분자 화합물류를 재활용되기에 적합하게 할 수 있고, 유기성분류를 폐기물 고형연료나 건조사료로 만들 경우에 이물질이 거의 함유되지 않은 양질의 원료가 되게 하였으며, 유기성분류를 소각처리시 폐합성 고분자 화합물류가 상기 유기성분류에 거의 함유되지 않아 대기 오염을 방지할 수 있었다.As described above, in the present invention as described above, organic components, non-ferrous metals, glassware, waste synthetic polymer compounds, etc. are carefully separated from industrial and household wastes that are dried by selectively removing ferrous metals and combustible wastes such as waste vinyl and waste papers in the pretreatment process.

도 1은 본 발명에 따라 효율적인 폐기물 선별방법을 설명하는 도면.1 is a view for explaining an efficient waste sorting method according to the present invention.

이하, 도 1을 참조하여, 본 발명에 따른 일실시예를 상세히 설명한다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to FIG. 1 .

본 실시예의 효율적인 폐기물 선별방법에 의해 선별 처리될 원료는 폐기물 하치장에 수거된 생활 폐기물을 파봉하여 일차적으로 자력선별기에 의하여 철금속을 분리한 후 파쇄기로 파쇄된 상태로 일차건조를 거쳐 종이류, 비닐류 등의 경량물이 제거된 폐기물이거나, 또는 폐기물 하치장에 수거된 산업 폐기물을 일차적으로 자력선별에 의하여 철금속을 분리한 후 파쇄기로 파쇄된 상태로 건조를 거쳐 종이류, 비닐류 등의 경량물이 제거된 폐기물이다.The raw materials to be sorted and treated by the efficient waste sorting method of this embodiment are first dried by shredding with a shredder after breaking up household waste collected in a waste dump, separating ferrous metals by a magnetic separator, and then drying paper, vinyl, etc. Wastes from which the light weight of the industrial waste has been removed, or the industrial waste collected in the waste dump is primarily separated from ferrous metals by magnetic sorting and then shredded with a shredder and dried to remove lightweight materials such as papers and vinyls. am.

전처리 공정에서 종이류, 비닐류가 제거되어 건조된 원료인 폐기물이 생활 폐기물인 경우에는 상기 생활 폐기물이 유기성분류인 음식물을 대다수 포함하고 있는 관계로 함수율이 높아 전처리 공정에서 한 번의 건조공정으로 원하는 함수율까지 건조시킬 수 없어 한 번더 2차 건조기(10)에서 건조 처리되어 분쇄기(20)에 투입되지만, 산업 폐기물인 경우에는 상기 산업 폐기물이 유기성분류인 음식물을 거의 포함하고 있지 않은 관계로 함수율이 높지 않아 전처리 공정에서의 한 번의 건조공정만으로 원하는 함수율까지 건조시킬 수 있어 또 다시 건조 처리되지 않고 그대로 분쇄기(20)에 투입된다.If the waste, which is a raw material that has been dried by removing papers and vinyls in the pre-treatment process, is household waste, the moisture content is high because the household waste contains most of the food, which is an organic component. It is impossible to do so, so it is dried in the secondary dryer 10 once more and put into the grinder 20, but in the case of industrial waste, the water content is not high because the industrial waste hardly contains food as an organic component, so the pretreatment process It can be dried to a desired moisture content with only one drying process in

여기에서, 상기 생활 폐기물이 선별 처리되기 전에 한 번더 2차 건조기(10)에서 원하는 함수율로 건조 처리되는 이유는 함수율에 따라 그 중량을 달리하는 유기성분류인 음식물을 10% 이하로 건조시키지 않으면, 음식물을 비철금속류, 초자기류 및 폐합성 고분자 화합물류로 부터 선별할 수 없기 때문이다.Here, the reason why the household waste is dried to a desired moisture content in the secondary dryer 10 once more before being sorted is that the food, which is an organic component, which has a different weight depending on the moisture content, is not dried to 10% or less. This is because it cannot be selected from non-ferrous metals, super porcelain, and waste synthetic high molecular compounds.

상기 분쇄기(20)에서 상기 원료를 진동 및 풍력을 이용하여 초자기류, 비철금속류, 폐합성 고분자 화합물류, 유기성분류 등을 선별하기 전에 미세하게 분쇄하는 이유는 상기 원료에 함유된 초자기류, 비철금속류, 폐합성 고분자 화합물류가 전처리 공정에서 파쇄된 형상의 크기에 따라 그 중량을 달리하기 때문이다.The reason for finely pulverizing the raw material in the grinder 20 before sorting the super-magnetic flow, non-ferrous metal, waste synthetic polymer compound, organic component, etc. by using vibration and wind power is the ultra-porcelain flow and non-ferrous metals contained in the raw material. , because the weight of the waste synthetic polymer compounds varies according to the size of the crushed shape in the pretreatment process.
