본 고안은 하, 폐수 슬러지의 자원 재활용 장치에 관한 것으로, 더욱 상세하게는 하수(폐)종말 처리장에서 발생하는 함수율이 높은 슬러지를 1차로 고압 탈수하고, 2차로 열매체 건조기를 통해 건조한 후 3차로 완전건조 부분반송 혼합방식에 의해 함수율 10 내지 20 중량%로 만들어 시멘트 원료, 소각용 연료, 탄화를 위한 원료, 퇴비 또는 복토용 원료로 자원화할 수 있는 하, 폐수 슬러지의 자원 재활용 장치에 관한 것이다.The present invention relates to a resource recycling apparatus for sewage and wastewater sludge, and more specifically, high-pressure dewatering of sludge having high moisture content generated in sewage (waste) end treatment plant is firstly depressurized, secondly dried through a heat medium dryer, and then completely thirdly. The present invention relates to a resource recycling apparatus for wastewater sludge, which can be recycled into a cement raw material, an incineration fuel, a carbonization raw material, a compost or a cover raw material by making a water content of 10 to 20% by weight by a dry partial conveying mixing method.

함수율이 높은 하수 슬러지는 현재까지 대부분 해양 투기와 매립에 의존하여 처리하였으나, 해양 오염, 악취, 침출수 발생 등의 2차 환경오염을 유발하는 문제점이 있다.Most sewage sludge with high water content has been treated so far depending on ocean dumping and landfill, but there is a problem of causing secondary environmental pollution such as marine pollution, odor, and leachate generation.

특히, 이와 같은 슬러지는 시멘트 원료, 소각용 연료, 탄화 원료, 퇴비 또는 복토용 원료로 활용됨에 있어 효율적인 저장 장치나 고효율 저에너지의 건조 시스템이 개발이 시급한 실정에 있다.In particular, such sludge is urgently needed to develop an efficient storage device or a high-efficiency low-energy drying system for use as cement raw material, incineration fuel, carbonization raw material, compost or cover material.

이와 같은 문제점을 해소하기 위해 제안된 종래 기술에 의한 슬러지 건조 장치를 간단히 설명하면, 건조 장치는 천정 크레인 → 슬러지 투입호파 → 이송스크류 컨베이어 → 1차 회전식 직접 열풍 건조기 → 배출기 → 2차 다공성 망체 회전식 건조기 → 배출기로 구성되어 있으며 부대 설비로는 열풍 제공수단, 집진등 배가스 정화설비로 구성되어 있다.The sludge drying apparatus according to the related art proposed to solve the above problems is briefly described, and the drying apparatus includes a ceiling crane → a sludge feeding filter → a conveying screw conveyor → a primary rotary direct hot air dryer → an ejector → a secondary porous mesh rotary dryer. → It is composed of discharger, and additional equipment consists of flue gas purification equipment such as hot air supply means and dust collection.

It is obvious that it belongs to the technical idea of the.

이상의 구성을 갖는 본 고안은 함수율이 높은 하폐수 슬러지를 건조하고, 첨가 부수재를 혼합하여 팰릿화하여 소결시켜 나노급 기공이 다수 있는 초경량 골재로 자원화함은 물론, 소성후 고온 폐열을 회수하여 건조기에 공급함으로써, 연료의 절감하고 슬러지의 처리시 발생하는 유해물질을 정화하여 배출함으로써 2차 환경오염을 완전히 제거할 수 있는 효과가 있다.The present invention having the above-described constitution is to dry sewage sludge with high water content, and to mix and pellet the added ancillary materials to pelletize and sinter them, to recycle them into ultra-light aggregates having many nano-grade pores, as well as to recover high-temperature waste heat after firing. By supplying fuel, it is possible to completely eliminate secondary environmental pollution by reducing fuel and purifying and discharging harmful substances generated during the treatment of sludge.
