It is.
한편 슬러지는 정수나 폐수처리과정에서 수중의 부유물이 액체로부터 분리되어 침전된 찌꺼기를 말하는 데 90% 이상의 많은 수분을 함유하고 있으며 이러한 슬러지를 고형연료로 제조하기 위해서는 낮은 함수율과 높은 칼로리, 균일한 배합율, 고체연료 사용로에서 사용이 가능할 것 등의 여러 조건이 요구되는 데 이중에서 함수율을 낮추는 데 가장 곤란을 겪고 있다.     On the other hand, sludge means more than 90% of water, which refers to the sediment that is separated from the liquid and precipitated from the liquid during the purification or wastewater treatment process. To produce such sludge as a solid fuel, it has a low water content, high calories, and a uniform mixing ratio. However, many conditions such as being able to be used in a solid fuel furnace are the most difficult to lower the moisture content.
상기에서 살펴본 바와 같이 많은 수분을 함유하고 있는 슬러지를 고형연료의 원료로 사용하기 위해서는 수분을 제거하기 위한 공정이 필수적으로 요구되며 이러한 수분제거공정은 전체 공정에서 상당한 부분을 차지하여 슬러지를 이용한 고형연료의 제조에 비경제적인 요인이 되었다.As described above, in order to use the sludge containing a lot of water as a raw material of the solid fuel, a process for removing water is essential, and this water removal process takes a substantial part of the overall process and uses sludge solid fuel. Has become an uneconomical factor in the manufacture of
또한 슬러지의 수분제거는 대부분 원심분리에 의한 탈수방법으로 이루어지는 데 이러한 슬러지의 탈수방법은 슬러지에 포함된 미세입자가 폐수와 함께 유출되어 칼로리 저하, 발열량 감소로 슬러지의 재활용 효율성이 저조하게 되고 폐수정화처리시설이 요구되는 등이 문제가 있었다.In addition, most of the water removal of sludge consists of dehydration method by centrifugation.In this sludge dewatering method, sludge fine particles contained in the sludge flow out together with the waste water, resulting in low sludge recycling efficiency due to reduced calories and reduced calorific value. There was a problem such as the need for a treatment facility.
또한 폐플라스틱을 고형원료로 사용하기 위해 파쇄후 분쇄과정을 거쳐 탈수하여 건조된 슬러지와 혼합과정을 다시 별도로 수행하게 되어 고형원료의 제조공정이 복잡하게 되고 많은 시간이 소요되어 고형연료의 효율성과 생산성을 떨어뜨리는 요인이 되었다.In addition, in order to use waste plastic as a solid raw material, it is dehydrated after crushing and then dehydrated and mixed with the dried sludge again, which makes the manufacturing process of the solid raw material complicated and takes a lot of time. It became a factor to drop.
이에 본 발명에서는 폐플라스틱 분쇄와 슬러지 건조과정을 이들을 혼합하는 과정에서 함께 수행하여 폐플라스틱과 슬러지를 합성한 고형연료의 제조에 있어서 고형연료의 제조효율성을 높여 생산성 향상 등으로 고형연료의 경제성을 높이고자 하는 것이다.Therefore, in the present invention, waste plastic pulverization and sludge drying process are performed together in the process of mixing them to increase the production efficiency of solid fuel in the production of solid fuel synthesized from waste plastic and sludge, thereby increasing the economic efficiency of solid fuel by improving productivity. I will.
즉, 본 발명은 폐플라스틱을 분쇄하고 슬러지와 혼합하는 과정에서 슬러지의 건조가 이루어지게 하여 폐플라스틱 분쇄작업과 슬러지의 건조작업을 별도로 수행함이 없이 이들을 혼합과정에서 분쇄 및 건조가 이루어지게 함으로써 고형연료의 제조공정과 시간을 단축하여 고형연료의 제조효율성을 높여 생산성 향상 등에 기여하고 이로부터 고형연료의 경제성을 더욱 충족시키고자 하는 것이다.That is, the present invention is to dry the sludge in the process of pulverizing the waste plastic and mixing with the sludge, so that the solid fuel by pulverizing and drying in the mixing process without separately performing the waste plastic grinding operation and drying of the sludge It is to shorten the manufacturing process and time, thereby increasing the production efficiency of solid fuels, thereby contributing to productivity improvement, and further satisfying the economics of solid fuels.
