상기 가연성폐기물의 펠릿 성형단계에서는 분쇄기에 의해 분쇄됨과 아울러 건조되고, 가연성폐기물을 용융시켜 성분을 균일하게 하고, 이후 급냉시켜 가연성폐기물의 펠릿을 얻게 되는 것이며, 예를들어, 가연성폐기물이 고속용융믹서(400)에 투입되어 고속용융믹서(400)의 밀폐된 내부에서 회전날개(412)와 고정날개(414) 사이에서 분쇄되고, 상기 회전날개(412)의 고속 회전에 의해 발생하는 마찰열로 용융되며, 이후 고속용융믹서(400) 내부에 분사되는 냉각수에 의해 급냉되어 다시 회전날개(412)와 고정날개(414)에 의해 입체형(粒體形)으로 파열됨으로써 가연성폐기물 펠릿이 만들어진다.In the pellet forming step of the combustible wastes, the combustible wastes are pulverized and dried, the combustible wastes are melted to homogenize the components, and then quenched to obtain pellets of the combustible wastes. Is injected into the 400 is crushed between the rotary blade 412 and the fixed blade 414 in the sealed interior of the high-speed melting mixer 400, and is melted by the frictional heat generated by the high-speed rotation of the rotary blade 412 Then, it is quenched by the cooling water sprayed into the high-speed melting mixer 400, and then ruptured in three-dimensional shape by the rotary blade 412 and the fixed blade 414 again to create a flammable waste pellets.
상기 고속용융믹서(400)에서 성형되는 가연성폐기물 펠릿은 설정된 입도 범위를 만족하게 되면 배출용 에어실린더(424)에 의해 배출구가 열리고, 배출구로부터 배출된 펠릿은 배출슈트(420)를 통해 저장소(500)로 이송하여 저장됨으로써 항상 균일한 입도의 폐플라스틱 펠릿을 얻을 수 있게 된다.When the flammable waste pellets formed in the high speed melting mixer 400 satisfy the set particle size range, the discharge port is opened by the discharge air cylinder 424, and the pellet discharged from the discharge port is stored in the reservoir 500 through the discharge chute 420. By transporting and storing), waste plastic pellets of uniform particle size can be obtained at all times.
이와 같이 하여, 고속용융믹서(400)에서 배출되어 저장소(500)에 저장된 가연성폐기물 펠릿, 즉 가연성폐기물 고형연료는 포장기(600)에서 포장 후 반출기(700)에 의해 반출(搬出)시켜 사용처로 출하한다.In this way, the combustible waste pellets, ie, combustible waste solid fuel, discharged from the high-speed melting mixer 400 and stored in the storage 500 are taken out by the ejector 700 after being packed in the packing machine 600 to be used. Ship it.
가연성폐기물을 재활용하여 고형연료로 생산함으로서 폐기물 처리에 따른 비용, 노력, 부대시설의 소비를 절약하고, 환경오염, 국토보존에 미치는 여러 가지 문제점을 감소시키는 효과가 있다.By recycling flammable waste as solid fuel, it saves cost, effort, and consumption of auxiliary facilities, and reduces various problems on environmental pollution and land conservation.
또한 지역특성에 맞는 시설 및 규모로 제작이 가능하고, 전 공정이 완전 밀폐형으로 제작되므로 공정운전 중 발생되는 2차오염을 최소화할 수 있으며, 중앙제어 시스템에 의한 자동운전가능-인건비 등의 유지관리비 절감할 수 있는 효과가 있다.In addition, it is possible to manufacture in facilities and scale suitable for local characteristics, and because the whole process is manufactured in a completely sealed type, it can minimize secondary pollution generated during process operation, and it can be operated automatically by a central control system. There is a saving effect.
