Description

슬러리 및 자원 재활용 여과 건조 장치{FILTERING AND DRYING APPARATUS FOR WASTES RECYCLING}FILTERING AND DRYING APPARATUS FOR WASTES RECYCLING}

본 발명은 오폐수를 여과 처리하면서 그 중에 포함되어 있는 재활용 가능한 슬러리 및 자원을 재활용할 수 있도록 슬러지를 건조 처리할 수 있도록 한, 슬러리 및 자원 재활용 여과 건조 장치에 관한 것이다.
The present invention relates to a slurry and resource recycling filtration drying apparatus, which allows the sludge to be dried to recycle waste slurry and resources contained therein while filtering waste water.

산업시설 등에서 배출되는 각종 오폐수에는 다량의 입자상 물질이 포함되어 있어 그대로 배출될 경우 하천을 오염시키게 되므로 오폐수를 배출하는 시설에는 입자상 물질의 제거를 위한 제거장치가 마련된다.Various wastewater discharged from industrial facilities contains a large amount of particulate matter, and if discharged as it is, it pollutes the river. Thus, a wastewater discharge facility is provided with a removal device for removing particulate matter.

과거 오폐수로부터 입자상 물질을 제거하기 위한 제거장치의 대부분은 여과포에 오폐수를 투입한 후 여과포를 압착하여 여과포 내에 걸러진 입자상 물질을 제거하는 방식이었다.In the past, most of the removal apparatuses for removing particulate matter from wastewater have been introduced into the filter cloth, and then the filter cloth is compressed to remove the particulate matter filtered in the filter cloth.

이러한 여과포 압착을 통한 입자상 물질 제거 장치는 여과포 내에 다량의 입자상 물질이 걸러진 상태에서 작업자가 수작업을 통해 걸러진 물질을 여과포 내부로부터 수거해야 하므로 연속작업이 불가능한 문제점이 있었다.The particulate matter removing apparatus through compression of the filter cloth has a problem in that continuous operation is impossible because the worker has to collect the filtered material from the inside of the filter cloth by a large amount of particulate matter in the filter cloth.

또한, 상기와 같은 여과포 압착을 통한 입자상 물질 제거 장치는 다량의 오폐수를 처리하기 위하여 다수 개의 여과포가 연속되게 설치되어야 하는 바, 설비 규모가 대형으로 커지며, 제조 단가가 상승하므로 소규모 시설이나 영세업자는 사용에 곤란함이 따르는 문제점이 있었다.In addition, the particulate matter removal apparatus through compression of the filter cloth as described above, in order to treat a large amount of waste water, a plurality of filter cloths must be continuously installed. There was a problem that is difficult to use.

최근에는 이러한 문제점을 해소하기 위하여 필터를 이용한 제거장치가 제안된 바 있다.Recently, a filter using a filter has been proposed to solve this problem.

그러나, 이러한 필터가 여과포와 마찬가지의 메쉬 구조로 이루어져 있어 필터 표면에 입자상 물질이 점착되어 시간이 경과하면서 점차로 여과 효율이 떨어져 여과 필터 표면을 세척하거나 교체해 주어야만 하는 문제점이 있었다.However, such a filter has a mesh structure similar to that of the filter cloth, so that particulate matter adheres to the filter surface, so that the filtration efficiency gradually decreases over time, and thus the filter filter surface has to be washed or replaced.

상기와 같은 종래 기술에서 발생되는 문제점을 해소하기 위한 것으로 "음식물쓰레기 처리장치의 탈수액 고액분리기"(한국 공개특허공보 제10-2010-0074613호) 및 "진공 여과장치"(한국 등록특허공보 제10-0324403호)와 같은 기술들이 공개된 바 있다.In order to solve the problems caused in the prior art as described above, "dehydration liquid solid separator of food waste treatment apparatus" (Korea Patent Publication No. 10-2010-0074613) and "vacuum filtration device" (Korea Patent Publication No. 10-0324403) have been published.

상기 기술은 원통형의 스크린 드럼의 표면에 규조토액을 공급하면서 회전시키거나 세라믹이 소결 성형된 드럼을 회전시키고, 이때 음식물 찌꺼기가 걸러지면서 여과 처리되도록 하는 한편, 스크린 드럼의 일측에 칼날을 설치하여 달라붙은 규조토와 음식물찌꺼기를 분리하도록 하였다.The technique rotates while supplying diatomaceous earth liquid to the surface of the cylindrical screen drum or rotates the ceramic-sintered drum, which filters and filters food waste, while installing a blade on one side of the screen drum. Separated diatomaceous earth and food waste were separated.

그런데, 상기와 같은 장치는 스크린드럼이 회전하도록 설치된 수조 상부가 개방된 상태로 형성되어 있어 스크린드럼의 회전 중에 표면에 묻은 음식물찌꺼기가 주변으로 비산하므로 주변 환경이 현저하게 오염되는 문제점이 있었다.However, such a device has a problem in that the top of the water tank installed to rotate the screen drum is formed in an open state, and thus, food waste deposited on the surface is scattered to the surroundings during the rotation of the screen drum.

또한, 칼날에 의해 걸러진 이물질은 항상 젖은 상태로 있게 되어 슬러지의 후처리를 위해서는 별도의 건조 공정을 거쳐야 하므로 재활용에 상당한 설비 투자가 필요한 문제점도 있었다.
In addition, the foreign matter filtered by the blade is always in a wet state, so the post-treatment of the sludge has to go through a separate drying process, there was also a problem that requires a significant investment in recycling.
