Description
본 발명은 수분을 다량 함유한 슬러지나 음식물쓰레기을 고주파와 적외선을 병용하여 제거하는 장치에 관한 것으로, 더욱 상세하게는 컨베이어 밸트를 통해 이송되는 슬러지나 음식물쓰레기에 초음파와 적외선을 조사하여 그 속에 포함된 수분을 증발/기화시켜 제거하는 방법 및 장치에 관한 것이다.일반적으로, 가정이나 식당 혹은 단체 급식장소에서는 식사후 혹은 배식 후 남는 음식물이 내량으로 배출되어지게 된다.이러한 음식물 쓰레기는 매립하거나 수거하여 가금의 사료로 재가공되기도 한다. 특히 재가공하는 과정에 음식물 쓰레기에 포함된 수분은 게거되어야 한다.이외에도 오폐수속에 포함된 슬러지등은 별도로 수거하여 폐기처리하고 있으나 그 속에 포함된 수분의 함량이 높아(함수율이 75%) 후처리과정에서 많은 비용이 소요되고 있다.이러한 문제를 해결하기 위하여 압축방법과 장치를 이용하여 대부분 처리하는 것이 대부분이나 최대 효율치도 함수율이 73%정도이기 때문에 크게 효과가 떨어진다.그리고, 함수율이 높은 슬러지의 처리과정중 소각 및 매립에 소요되는 비용이 많고 또 2차 공해발생 즉 매립장에서 발생하는 침출수로 인해 지하수가 오염되는 등 문제점이 있어 왔다.참고로, 년간 서울에서 발생되는 슬러지량과 그 처리비용을 아래의 표와 같다. The present invention relates to a device for removing sludge or food waste containing a large amount of water in combination with high frequency and infrared rays, and more particularly, to irradiate ultrasonic and infrared rays to sludge or food waste that is transported through a conveyor belt. The present invention relates to a method and apparatus for evaporating / vaporizing water to remove water. Generally, at home, in a restaurant, or in a group feeding place, food left after meals or after meals are discharged to the internal capacity. It can also be reprocessed into feed. In particular, during the reprocessing process, the water contained in the food waste should be collected.In addition, the sludge contained in the wastewater is collected and disposed of separately, but the water content in it is high (75% water content). In order to solve this problem, most of the processing using the compression method and the device is mostly effective, but the maximum efficiency is also very ineffective because the water content is about 73%. The cost of heavy incineration and landfill is high, and there have been problems such as secondary pollution, that is, groundwater contamination due to leachate from landfills. Same as the table.
본 발명은 전술한 바와 같이 슬러지나 음식물 쓰레기에 들어 있는 수분의 제거시 컨베이어벨트를 통해 이송되는 슬러지나 음식물 쓰레기를 고주파장치와 적외선을 이용하여 수분을 증발시켜 제거하는 제거방법 및 장치를 제공하는데 있다.The present invention is to provide a method and apparatus for removing the sludge or food waste transported through the conveyor belt to remove the water in the sludge or food waste by evaporating the water using a high frequency device and infrared rays as described above. .
