Abstract

PURPOSE: A method for manufacturing a solid fuel using paper mill sludge is provided to increase industrial utilization rate of wastes by crushing the carbonized sludge into a sawdust shape after carbonizing the surface of sludge of the paper mill sorted and dried so that the sawdust shaped sludge can be industrially utilized as a solid fuel. CONSTITUTION: The method for manufacturing a solid fuel using paper mill sludge comprises raw material preparation step(1) of preparing raw material by pressing the sludge discharged from the paper mill to a certain size so that the sludge is formed in a lump having moisture content of 15 to 20%; sorting step(2) of sorting the dismantled sludge to remove foreign materials after transporting the lump to a works and dismantling the lump; drying step(3) of injecting the sorted sludge into a dryer to remove water content; carbonization step(4) of injecting the dried sludge into a rotary carbonizer which supplies hot air of 280 to 300 deg.C to a supply pipe so that the surface of the sludge is carbonized by rotating the carbonizer; crushing step(5) of crushing the carbonized sludge in a sawdust shape using a crusher; and packing step(6) of packing the crushed sludge as a solid fuel.

제지공장의 슬러지를 이용한 땔감의 제조방법{METHOD FOR MANUFACTURING FIREWOOD USING SLUDGE OF PAPER MILL}METHODS FOR MANUFACTURING FIREWOOD USING SLUDGE OF PAPER MILL}

본 발명은 제지공장의 슬러지를 땔감으로 제조하는 방법이다.The present invention is a method for producing sludge from a paper mill.

즉, 제지공장에는 대량의 제지슬러지가 발생하고 있고 지금까지는 이것을 산업폐기물로 버리고 있다.In other words, a large amount of paper sludge has been generated in the paper mill, and so far it has been discarded as industrial waste.

제지공장의 슬러지는 셀룰로오스 및 헤미셀룰로오스와 같은 탄수화물로 구성된 섬유질 세립물과 클레이(알미늄 실리케이트) 충전제 및 코팅제 등의 무기물질 및 소량의 화학약품을 함유하고 있다.Sludges in paper mills contain small amounts of chemicals and inorganic substances such as fibrous fines consisting of carbohydrates such as cellulose and hemicellulose, and clay (aluminum silicate) fillers and coatings.

따라서, 상기와 같은 이유로 폐기물을 매립하는 등으로 처리하고 있으나 환경을 해하는 문제가 있고 달리 이용방법이 개발되지 않아서 상당한 자원이 낭비되는 것이 현실이다.Therefore, although the waste is disposed of in landfills and the like for the above reasons, there is a problem that harms the environment, and in fact, a significant resource is wasted because no use method is developed.

본 발명은 상기와 같은 불편을 해소시키기 위해 개발된 것으로 슬러지를 땔감으로 제조하는 것이다.The present invention was developed to eliminate the inconvenience as described above is to manufacture the sludge as a firewood.

이를 보다 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

도 1은 본 발명의 처리장치 계통도.1 is a processing system diagram of the present invention.

도 2는 본 발명의 탄화장치 예시도이다.Figure 2 is an illustration of a carbonization device of the present invention.

본 발명의 제조방법은 다음과 같다.The production method of the present invention is as follows.

즉, 본 발명은 제지슬러지를 탈수하여 선별한 후 건조시켜서 표면을 탄화시키고 파쇄하여 톱밥형태의 땔감으로 제조된다.That is, in the present invention, the paper sludge is dehydrated, sorted, dried, carbonized and crushed to prepare a sawdust type firewood.

이를위해 본 발명은 배출되는 슬러지를 일정크기로 압착하여 수분함량이 15~20%되는 뭉치(1) 상태로 만들어서 작업장에 운반한 후 이를 해체하여 이물질을 제거하는 선별작업(2)을 하고 이를 건조기(3)에 넣어 수분을 건조시킨 다음 280~300℃ 되는 열기가 공급관(4a)으로 공급되는 회전형 탄화기(4)에 투입하고 탄화기를 회전시켜 통과시키므로서 슬러지 표면을 탄화시킨 다음 파쇄기(5)로 파쇄하여 톱밥형태의 땔감으로 만들어 포장한다.To this end, the present invention compresses the discharged sludge to a certain size to make a bundle (1) state of water content of 15 to 20% (1) and transport it to the workshop and then dismantle it to remove the foreign matter to remove the foreign matter and the dryer (3) to dry the water, and then the heat of 280 ~ 300 ℃ is put into the rotary carbonization machine (4) supplied to the supply pipe (4a) and carbonized the sludge surface by rotating and passing the carbonizer and then shredder (5) Shred in) and make it into sawdust type firewood.

이와같이된 본 발명은 슬러지를 톱밥형태의 땔감으로 제조하기 때문에 난방장치를 비롯하여 산업용 보일러 등의 땔감으로 사용하기 쉽고 열효율이 높으며 폐기되는 슬러지를 건조하여 약간 탄화시킨 다음 톱밥형태로 제조하였기 때문에 취급은 물론 사용이 편리하여 땔감으로 요긴하게 쓸 수 있는 이점을 얻는 것이다.Since the present invention is manufactured in the form of sawdust type of sludge, the present invention is easy to use as a firewood and other industrial boilers, and the thermal efficiency is high. It is easy to use and it is useful to use as a firewood.
