Description

슬러지 건조장치 및 건조방법{An apparatus and method for drying sludge}An apparatus and method for drying sludge

본 발명은 슬러지 건조장치 및 건조방법에 관한 것이다. 보다 구체적으로 스팀에 의해 가열되는 드럼 사이에 두 개의 벨트를 걸고 그 사이로 슬러지를 통과시켜 슬러지가 드럼의 표면에 접촉하면서 건조되도록 한 슬러지 건조장치 및 건조방법에 관한 것이다.The present invention relates to a sludge drying apparatus and a drying method. More specifically, the present invention relates to a sludge drying apparatus and a drying method in which two belts are sandwiched between drums heated by steam, and the sludge is passed therebetween so that the sludge is dried while contacting the surface of the drum.

슬러지는 활성오니법으로 폐수를 정화처리하는 과정에서 대량 발생되는 유기성 폐기물로써 그 자체는 높은 열량을 갖고 있으며, 일반적으로 산업체에서 배출되는 각종 산업폐기물 중 고형 폐기물은 재래식 소각설비로도 비교적 쉽게 연소가 가능하므로 대부분 자체 소각 처리하여 폐열 회수 등 에너지 자원으로 재활용하고 있으나, 많은 양의 수분을 포함하고 있는 슬러지의 경우는 수분 때문에 소각이 매우 어려운 실정이다.Sludge is an organic waste that is generated in a large amount in the process of purifying wastewater by the activated sludge method, and it has a high calorie value.In general, solid waste among various industrial wastes discharged from the industry is relatively easily burned by conventional incineration facilities. Most of them are incinerated and recycled as energy resources such as waste heat recovery. However, in case of sludge containing a large amount of water, incineration is very difficult due to moisture.

현재 대다수의 산업체에서는 농축된 슬러지에 탈수가 잘 되도록 고분자 응입제 등 화학약품을 첨가하여 벨트 프레스 등 기계식 탈수방식을 사용하여 함수율 70-80% 까지는 탈수가 가능하나 자체 연소가 가능한 30% 미만으로의 탈수는 불가능한 상태이다. 따라서 대부분의 산업체 또는 하수종말처리장에서 발생된 슬러지들은 아직 자체소각 처리하지 못하고 폐기물 처리 전문 업체에 용역을 주어 매립처리하고 있는 실정이다. 그러나, 이는 환경문제에 대한 사회 전반적인 인식과 매립처리시설의 한계로 인해 많은 처리비용을 부담하게 되었고 이러한 현상은 점점 더 심화되고 있다.Currently, most industries add chemicals such as polymer coagulants to dewater the concentrated sludge and use mechanical dehydration method such as belt press to dehydrate up to 70-80% of water content but to less than 30% of self-combustion. Dehydration is impossible. Therefore, the sludge generated in most industrial or sewage treatment plants has not been incinerated yet, but has been serviced by a waste disposal company for landfill treatment. However, due to the general social awareness of environmental problems and the limitations of landfill facilities, this has caused a lot of treatment costs, and this phenomenon is getting worse.

최근 일부 대기업에서는 소각로에서 소각시 발생된 배기가스를 이용한 로타리 킬른식 건조기로 슬러지를 열풍 건조후 소각시키는 시스템을 설치하고 있다. 그러나 이는 설비 규모가 대형이어서 설치 면적이 크고, 수입품으로 거액의 설비비가 소요되며, 비싼 고분자 응집제를 필수적으로 첨가해야 하는 등 유지관리비가 많이 드는 문제가 있다.Recently, some large corporations have installed a system to incinerate sludge after hot air drying by rotary kiln type dryer using exhaust gas generated in incinerator. However, this is a large installation size, the installation area is large, a large amount of equipment costs as imports, there is a problem that a lot of maintenance costs, such as the need to add expensive polymer flocculant essential.

본 발명의 목적은 건조 효율이 우수하고 스팀 폐열을 이용할 수 있어 에너지 절약에 유리한 슬러지 건조장치 및 건조방법을 제공하는 것이다.An object of the present invention is to provide a sludge drying apparatus and a drying method which is excellent in drying efficiency and can use steam waste heat, which is advantageous for energy saving.

본 발명의 다른 목적은 슬러지의 건조과정에서 발생하는 불쾌한 공기를 유출시키지 않고 내부에서 순환할 수 있도록 하여 쾌적한 환경을 유지할 수 있고, 슬러지의 건조를 위한 공기를 사전에 건조 및 가열시켜 건조 효율을 향상시킬 수 있는 슬러지 건조장치 및 건조방법을 제공하는 것이다.Another object of the present invention is to maintain a pleasant environment by allowing the inside of the sludge to circulate without the unpleasant air generated during the drying process of the sludge, to improve the drying efficiency by drying and heating the air for drying the sludge in advance It is to provide a sludge drying apparatus and a drying method that can be.
