Abstract

The present invention relates to a composite rotary dehydrator for dehydrating sludge. More specifically, the present invention relates to the composite rotary dehydrator for dehydrating sludge, wherein only concentrated sludge whose moisture has been mostly removed by a drum screen is introduced into a rotary dehydrator, thereby reducing a volume of the rotary dehydrator, and the concentrated sludge with the moisture removed is compressed and dehydrated to increase dehydration efficiency. For the purpose, the present invention provides the composite rotary dehydrator for dehydrating sludge, which comprises: a drum screen having a fine perforated net; a sludge transfer conveyer transferring concentrated sludge discharged by the drum screen; and a rotary dehydrator compressing and dehydrating the concentrated sludge transferred by the sludge transfer conveyer by rotation of a rotor simultaneously revolving and spinning by means of an eccentric shaft and a gear.

Description

슬러지 탈수용 복합 로터리 탈수장치 {Composite rotary device for dewatering sludge dewatering}{Composite rotary device for dewatering sludge dewatering for sludge dewatering}

본 발명은 슬러지 탈수용 복합 로터리 탈수장치에 관한 것이다. 보다 상세하게는, 드럼스크린으로 대부분의 수분을 제거한 후 농축된 슬러지만을 로터리탈수기로 투입함으로써 로터리탈수기의 용량을 줄일 수 있고, 수분이 제거된 농축 슬러지를 압착탈수함으로써 탈수효율을 향상시킬 수 있는 슬러지 탈수용 복합 로터리 탈수장치에 관한 것이다.The present invention relates to a complex rotary dewatering device for sludge dewatering. More specifically, it is possible to reduce the capacity of the rotary dehydrator by removing most of the moisture by the drum screen and then to introduce only the concentrated sludge into the rotary dehydrator, and the sludge capable of improving the dehydration efficiency by squeezing and dewatering the concentrated sludge, To a complex rotary dewatering device for dewatering.

하수처리장에서 발생하는 슬러지는 약 99%~97%의 수분과 고형물(슬러지)로 이루어져 있으며, 이러한 슬러지를 농축 및 탈수하여 한다.The sludge generated in the sewage treatment plant is composed of about 99% to 97% of water and solid matter (sludge), and this sludge is concentrated and dehydrated.

그러나 종래에는 하수처리장, 하천 및 해양바닥에 쌓인 퇴적물을 준설하는 과정에 발생하는 준설슬러지를 드럼 스크린 등의 장치를 이용하여 수분과 고형물로 분리하여 폐기처리하고 수분은 다시 하수 등의 저류조로 배출하여 왔다. However, conventionally, the dredging sludge generated in the process of dredging sediments accumulated in sewage treatment plants, rivers and marine floors is separated into water and solid materials by using a device such as a drum screen, and the water is discharged to a storage tank such as sewage again come.

이러한 문제점을 해결하기 위한 이러한 탈수처리 방법은 난탈수성의 슬러지로 인하여 슬러지에 포함된 수분을 효과적으로 분리하지 못하여 폐기하여야 하는 고형 슬러지의 양이 증가하고 이에 따른 처리비용이 증가할 뿐만 아니라 침전물들이 많이 혼합된 상태로 다시 탈수처리된 물이 저류조 등으로 배출되기 때문에 준설 슬러지의 탈수 효율성이 떨어진다는 문제가 있다.In order to solve this problem, the dehydration treatment method can not effectively separate the moisture contained in the sludge owing to the dewatering sludge, thereby increasing the amount of the solid sludge to be disposed of and increasing the treatment cost, There is a problem that the dewatering efficiency of the dredging sludge deteriorates because the water dehydrated again in the state of being discharged into the storage tank or the like.

또한, 종래의 로터리탈수기의 경우 슬러지의 탈수를 위하여 로터리탈수기에 슬러지를 투입 시, 슬러지에 포함된 많은 양의 수분(99%~97%)으로 인하여 압착탈수효율이 떨어질 뿐만 아니라 수분까지 함께 로터리탈수기에 투입되어야 하므로 로터리탈수기의 용량(크기)도 커져야 되며, 로터리탈수기의 용량이 커짐에 따라 과도한 비용과 동력 증가 등에 따른 유지관리비용이 증가하는 문제점이 있다.In addition, in the conventional rotary dehydrator, when the sludge is introduced into the rotary dehydrator for dewatering the sludge, the squeezing dewatering efficiency is lowered due to a large amount of water (99% to 97%) contained in the sludge, The size (capacity) of the rotary dehydrator must be increased. As the capacity of the rotary dehydrator increases, the maintenance cost increases due to excessive cost and power increase.
