Description

폐가전제품의 부산물을 이용한 고형화 연료 제조방법{Methods for manufacturing of solid fuels using waste material of electric home appliances}Method for manufacturing solid fuels using waste material of electric home appliances

본 발명은 폐가전제품의 부산물을 재활용하기 위한 방법에 관한 것으로, 특히 거의 전량 폐기되어 소각처리되고 있는 폐가전제품의 부산물을 연료로 재활용하므로써 폐기자원을 고부가가치화하기 위한 폐가전제품의 부산물을 이용한 고형화 연료제조방법에 관한 것이다.The present invention relates to a method for recycling by-products of waste home appliances, and in particular, by using by-products of waste home appliances for high value-added waste resources by recycling by-products of waste home appliances that are almost completely discarded and incinerated as fuel. It relates to a solidified fuel production method.

최근 산업사회의 발전과 생활수준의 향상으로 인해 가전제품이 엄청난 양으로 증가하고 있으며, 이와 비례하여 폐기된 가전제품들로 부터 부산되는 폐기물의 양 또한 다량 발생하고 있다.Recently, due to the development of the industrial society and the improvement of living standards, the amount of household appliances has increased enormously, and in proportion, the amount of wastes from the discarded household appliances is also generated.

그러나 지금까지 폐가전제품의 일부 중 재활용가능한 부분만을 선별하여 재생원료로 사용하거나 기타 폐플라스틱제품들과 함께 용융시켜 성형가공하므로써 건축용 판재 및 바닥재로 사용하고 있긴하나, 폐가전제품만을 별도로 재활용하기 위한 방법은 창안된 바 없으며, 이는 폐가전제품을 구성하는 물질들이 ABS수지(acrylonitrile butadiene styrene copolymer) 및 금속, 폴리우레탄, 스티로폼, 인쇄회로기판(Printed Circuit Boards)등과 같이 재활용이 곤란한 서로 다른 재질들이 다양하게 혼재되고 있기 때문이다.However, until now, only recyclable parts of waste household products are selected and used as recycled materials or melted together with other waste plastic products to be molded and used as building plates and flooring materials. No method has been invented, which means that the materials constituting the waste home appliances are different from those that are difficult to recycle such as ABS resin (acrylonitrile butadiene styrene copolymer) and metals, polyurethane, styrofoam, printed circuit boards, etc. This is because they are mixed.

따라서 결국 현재까지도 폐가전제품 부산물은 거의 전량 소각처리하거나 매립할 수 밖에 없는 실정인 바, 이처럼 소각처리의 경우는 연료낭비와 악취·다이옥신류 발생 등으로 인해 대기 및 수질오염의 원인이 되는 폐단을 갖는 것은 물론, 우리나라와 같이 연료를 대량 수입하고 있는 상태에서 엄청난 열량을 갖는 가연성물질들을 단순히 태워 없앤다는 것은 매우 안타까운 일이 아닐 수 없다.Therefore, until now, almost all by-products of waste household products have to be incinerated or landfilled.In this case, incineration treatment is necessary to eliminate wastes that cause air and water pollution due to waste of fuel, odors and dioxins. Of course, it is a pity to simply burn off the combustible materials with huge calories while importing a large amount of fuel like Korea.

따라서 본 발명자는 연료자원이 유한성으로 인해 대체연료의 필요성이 어느때보다 절실한 실정이고, 이로인해 현재 소각 및 매립에 의해 폐기하고 있는 가전제품 부산물의 활용을 연구하던 중, 가전제품 부산물은 거의 모두가 가연성이며, 특히 고열량을 발생시킬 수 있는 재질이라는 점에 착안하여 이들을 연료화하므로써 환경오염방지 및 자원의 낭비를 획기적으로 절감시킬 수 있도록 하였다.Therefore, the inventors of the present invention are more urgent than ever due to the finite nature of fuel resources, and thus, while researching the utilization of home appliance by-products currently disposed of by incineration and landfill, almost all home appliance by-products are flammable. In particular, it is possible to significantly reduce the waste of resources and prevent environmental pollution by fueling them with the idea that they can generate high calorific value.

이를 위해 본 발명자는 폐기된 가전제품을 파쇄하는 단계와, 상기 파쇄된 가전제품 부산물 중에서 금속류(금속, 비철금속 포함)를 제외한 부산물만을 선별해내는 단계와, 상기 선별된 금속류를 제외한 부산물(이하 비금속 부산물이라 한다) 중에서 열가소성 플라스틱의 함량을 측정하는 단계와, 상기 비금속 부산물에 포함된 열가소성 플라스틱의 양이 전체 중량비의 20%이하이면 20%이상이 되도록 열가소성 플라스틱을 첨가하는 단계와, 상기 비금속부산물을 열풍기가 구비된 원통체 속으로 통과시켜 고온의 와류공기에 의해 함수율이 조절되도록 하는 단계와, 상기 함수율이 조절된 비금속부산물을 호퍼에 저장해두는 단계와, 상기 호퍼로 부터 계량된 일정량의 비금속부산물을 마찰식 용융혼합기에 넣고 분쇄함과 동시에 보다 균일하게혼합되도록 하는 단계와, 상기 비금속부산물이 상기 마찰식 용융혼합기 내에서 플라스틱성분들이 마찰열에 의해 용융되면서 폐가전제품 부산물 조각들과 서로 엉기도록 하는 단계와, 상기 용융된 플라스틱성분이 폐가전제품 부산물과 결합되어 덩어리를 형성하게 되면 물을 분사하여 냉각시키므로써 작은 입상의 펠렛을 형성할 수 있도록 하는 단계를 포함하는 폐가전제품의 부산물을 이용한 고형화 연료 제조방법을 제공하기 위한 것이다.To this end, the present invention is a step of shredding the discarded household appliances, the step of sorting only by-products except for the metals (including metals, non-ferrous metals) from the shredded household appliances by-products, and by-products (hereinafter referred to as non-metal by-products) Measuring the content of the thermoplastic plastic, adding the thermoplastic plastic so that the amount of the thermoplastic plastic included in the non-metal by-product is 20% or more when the amount of the thermoplastic plastic is less than 20% of the total weight ratio, and the non-metal by-product is hot air blower. Passing through the cylindrical body is provided to control the moisture content by the hot vortex air, and storing the non-metal by-products having the water content is controlled in the hopper, and friction of a certain amount of non-metal by-products measured from the hopper To be mixed in a mechanical melt mixer and mixed more uniformly. And the non-metal by-products are entangled with the scrap of waste appliance by-products as the plastic components are melted by frictional heat in the friction melt mixer, and the molten plastic component is combined with the waste appliances by-products to agglomerate. Forming the to provide a method for producing a solidified fuel using the by-products of the waste home appliances comprising the step of forming a small granular pellet by spraying water to cool.

By spraying water to cool it, it is a step to form pellets of small granules, which can be produced by the solid fuel by-products of waste home appliances.

이를 바람직한 실시예를 들어 각 단계별로 상세히 설명하기로 한다.This will be described in detail for each step for the preferred embodiment.

실시예Example

본 발명에 필요한 폐기 가전제품(이하 폐가전제품이라 한다)들은 동사무소 및 가전제품제조공장 등으로 부터 수거되어지는데, 이때 폐가전제품의 종류와 크기는 본 발명에 있어 아무런 상관관계가 없다.The waste household appliances required for the present invention (hereinafter referred to as waste household appliances) are collected from offices and home appliance manufacturing plants, etc., where the type and size of waste household appliances have no correlation in the present invention.

상기 수거된 폐가전제품(100)들은 크레인 또는 기타 장비에 의해 파쇄기(110)에 넣어져 파쇄되어지는데, 상기 파쇄기는 종축 햄머식이 주로 사용되어진다.The collected household appliances 100 are put into the shredder 110 by a crane or other equipment to be shredded, the shredder is a longitudinal hammer type is mainly used.

또한 상기 파쇄기(110)에 의해 파쇄된 가전제품 조각, 즉 폐가전제품 부산물(111)들은 풍력 또는 자력을 이용하는 선별장치(120)를 거치게 되는데, 상기 선별장치는 금속 및 비철금속성분과 같이 비가연성이고 쉽게 분쇄가 되지 않는 물질을 걸러내기 위한 것이다.In addition, the pieces of household appliances shredded by the shredder 110, that is, waste home appliance by-products 111 are subjected to a sorting device 120 using wind or magnetic force. The sorting device is non-flammable, such as metal and nonferrous metal components. This is to filter out materials that are not easily crushed.

따라서 상기 선별장치에 의해 비금속 부산물(121)만이 선별되어지고, 상기 선별된 비금속 부산물(121)에 대해서는 작업자가 열가소성 플라스틱(122)의 함량을측정하게 된다. 이때 열가소성 플라스틱의 함량을 측정하는 이유는 상기 열가소성 플라스틱(122)이 에이비에스(ABS)수지 및 발포우레탄, 스티로폼, 인쇄회로기판 등과 같이 용융성이 좋지 못하고 서로 쉽게 융착되지 못하는 비금속 부산물(121)을 용융시킬 때 서로 결합시키기 위한 바인더(binder)기능을 하게 되는데, 상기 비금속 부산물에 포함된 열가소성 플라스틱의 양이 전체 중량비의 20%이하가 되면 충분한 바인더기능을 할 수 없기 때문이다.Therefore, only the non-metal by-products 121 are selected by the sorting device, and the operator measures the content of the thermoplastic plastic 122 for the selected non-metal by-products 121. In this case, the reason for measuring the content of the thermoplastic is that the thermoplastic 122 is a non-metal by-product 121 that does not have good meltability, such as ABS (ABS) resin and foamed urethane, styrofoam, printed circuit board is not easily fused with each other. When melting, the binder (binder) function to bind to each other, because the amount of the thermoplastic plastic contained in the non-metal by-products can not function enough binder when less than 20% of the total weight ratio.

따라서 열가소성 플라스틱(122)의 함량을 측정해서 20%이하라면 비금속 부산물(121)에 포함된 프라스틱의 함유량을 포함하여 중량비로 최소 20%이상이 되도록 열가소성 플라스틱을 첨가해 주어야 한다.Therefore, if the content of the thermoplastic plastic 122 is 20% or less, the thermoplastic plastic should be added to be at least 20% by weight, including the content of the plastic contained in the non-metal by-product 121.

본 발명에 있어서 상기 열가소성 플라스틱은 융착성을 가지는 열가소성수지를 의미하고, 특히 폴리에틸렌, 폴리프로필렌, 폴리스틸렌, 폴리비닐 등이 주로 사용되어질 것이며, 그중에서도 폴리에틸렌을 사용하는 것이 가장 바람직한 결과를 얻을 수 있다.In the present invention, the thermoplastic resin means a thermoplastic resin having adhesion, and in particular, polyethylene, polypropylene, polystyrene, polyvinyl, and the like will be mainly used, and among them, the most preferable result is polyethylene.

이때 상기 비금속부산물(121)과 열가소성 플라스틱 조각들의 혼합은 혼합기(130)에 의해 이루어지며, 상기 균일하게 혼합된 비금속부산물(131)들을 컨베이어벨트(140)에 의해 이송되어져 열풍기(151)가 구비된 원통체(150) 속을 통과하게 되는데, 이때 상기 비금속부산물(131)들이 원통체 내부를 통과하는 순간 열풍기에서 품어져 나온 고온의 와류공기에 의해 수분이 증발되면서 함수율이 조절되어진다.At this time, the mixing of the non-metal by-products 121 and the thermoplastic plastic pieces is made by the mixer 130, and the uniformly mixed non-metal by-products 131 are transferred by the conveyor belt 140 to provide the hot air blower 151. Pass through the cylindrical body 150, the moisture content is controlled by the evaporation of moisture by the hot vortex air from the hot air at the moment when the non-metal by-products 131 pass through the inside of the cylindrical body.

이때 비금속부산물(131)들의 함수율 조절은 본 발명에 있어서 매우 중요한요소로, 펠렛(170)을 형성함에 있어 상기 비금속부산물(131)들의 함수율에 따라 펠렛 형성시간이 현저하게 달라지기 때문이다.At this time, the moisture content control of the non-metal by-products 131 is a very important factor in the present invention, because the formation time of the pellets is significantly changed depending on the moisture content of the non-metal by-products 131.

즉 펠렛(170) 형성이 늦어지면 그만큼 장치의 가동으로 인한 에너지의 소모가 커질 수 밖에 없고, 이로인해 생산성의 저하 및 제조가격의 상승이 불가피하기 때문이다.That is, when the formation of the pellets 170 is delayed, the energy consumption due to the operation of the device is inevitably increased, thereby lowering the productivity and increasing the manufacturing price.

이때 함수율의 따른 펠렛형성시간의 차이를 표 1에 나타내었다.The difference in pellet formation time according to the moisture content is shown in Table 1.

함수율Water content 펠렛형성시간Pellet Forming Time 7%7% 14분14 minutes 17%17% 19분19 minutes 27%27% 24분24 minutes

즉 함수율 10% 추가시마다 펠렛형성시간은 5분씩 추가소요되었다.In other words, for every 10% of moisture content, pelleting time was additionally 5 minutes.

다음 상기 함수율이 조절된 비금속부산물(131)들을 일단 호퍼(160)에 저장하게 되는데 이는 마찰식 용융혼합기(170)가 일정량의 비금속부산물(131)만을 소화할 수 있기 때문이다.Next, the non-metal by-products 131 of which the moisture content is controlled are stored in the hopper 160 because the friction type melt mixer 170 can digest only a certain amount of the non-metal by-products 131.

따라서 상기 호퍼로 부터 일정량을 비금속부산물(131)을 계량하여 공지의 마찰식 용융혼합기(170)로 투입하게 되는데 상기 마찰식 용융혼합기(170)에 의해 비금속부산물(131)들이 분쇄와 동시에 다시 균일하게 섞이게 된다.Therefore, a certain amount of the non-metal by-product 131 is measured from the hopper and introduced into a known friction melt mixer 170. The non-metal by-product 131 is crushed and uniformly again by the friction melt mixer 170. It is mixed.

또한 상기 마찰식 용융혼합기(170)에 투입된 비금속부산물(131)들은 마찰식 용융혼합기(170)의 바닥에 형성된 회전칼날(172)에 의해 회전하면서 발생하는 마찰열에 의해 상기 비금속부산물(131) 중에 함유된 플라스틱성분이 먼저 용융되면서역시 비금속부산물(131) 중에 함유되어있는 비금속 부산물(121) 조각들과 서로 엉기게 된다.In addition, the non-metal by-products 131 introduced into the friction melt mixer 170 are contained in the non-metal by-product 131 by frictional heat generated while rotating by the rotary blade 172 formed on the bottom of the friction melt mixer 170. As the plastic component is melted first, it is also entangled with the nonmetal by-products 121 contained in the non-metal by-product 131.

이때 상기 비금속부산물(131)의 온도가 160℃정도에 이르게 되면 용융된 플라스틱성분은 비금속 부산물(121) 조각들과 결합되어 덩어리를 형성하게 되는데 이때 분사기(171)로 물을 분사하여 냉각시키므로써 직경이 1cm이내인 작은 입상의 펠렛(180)이 형성되어지는 것이다.In this case, when the temperature of the non-metal by-product 131 reaches about 160 ° C., the molten plastic component is combined with pieces of the non-metal by-product 121 to form a lump. In this case, water is injected into the injector 171 to cool the diameter. Small granular pellets 180 within this 1 cm are formed.

이처럼 본 발명은 매우 작은 입상을 가지며, 열량이 높은 폐가전제품 부산물 조각들이 점화온도가 낮은 가연성 플라스틱에 의해 균일하게 혼합되어 융착된 상태이므로 점화가 용이해지며, 연소력이 좋아지는 것은 물론, 화력이 균일하게 형성되므로 고체연료로 대체함에 있어 부족함이 없게 되는 것이다.As described above, the present invention has a very small granular shape, and since the by-product pieces of high-calorie waste home appliances are uniformly mixed and fused by flammable plastics having a low ignition temperature, ignition is facilitated, and combustion power is improved, as well as fire power. Since it is formed uniformly, there is no shortage of replacing the solid fuel.

본 발명은 다양한 성분으로 이루어지는 폐가전제품 부산물을 입상(粒狀)의 작은 펠렛형상으로 제조하게 되므로써 점화가 용이하게 되고, 연소력이 좋게 되며, 화력이 균일하여 비닐하우스나 발전소, 기타 여러 고체연료를 사용하는 곳에 무료로 또는 저렴한 금액으로 제공하므로써 종래 매립이나 단순한 소각을 통해 폐기하는 것보다는 경제적 효용가치를 향상시킬 수 있도록 하였고, 이로인한 폐자원의 고부가가치화 및 환경보호에 크게 이바지할 수 있도록 하였다.According to the present invention, since the by-products of various household waste products composed of various components are manufactured in the form of small pellets of granules, the ignition is easy, the combustion power is good, and the thermal power is uniform, so that the greenhouse, power plant, and other solid fuels By providing free or inexpensive place to use, it is possible to improve economic utility value rather than disposing through conventional landfill or simple incineration, and contribute greatly to high value added and environmental protection of waste resources. .
