Description

하수 및 분뇨, 음식물 찌꺼기 건조장치{A drying equipment to dry the sewage and manure, food waste}A drying equipment to dry the sewage and manure, food waste}

본 발명은 하수 및 분뇨, 음식물 찌꺼기 건조장치에 관한 기술로써, 보다 상세하게 설명하면 하우징 외부에 하우징 외부 면을 일정한 간격으로 감는 히팅케이블을 특수절연재로 충진한 히팅패드를 구비하여 하우징 내벽으로 전열되는 효과를 높이고, 히팅패드 외부에 보온재 케이싱 처리를 한 보온재를 구비하여 히팅온도가 오랫동안 유지되게 하는 하수 및 분뇨, 음식물 찌꺼기 건조장치에 관한 것이다. The present invention relates to a sewage and manure, food waste drying apparatus, which will be described in more detail is heated to the inner wall of the housing having a heating pad filled with a special insulating material winding the outer surface of the housing at regular intervals on the outside of the housing The present invention relates to a sewage and manure, food waste drying apparatus for enhancing the effect and having a heat insulating material which is treated with a heat insulating material casing outside the heating pad to maintain a heating temperature for a long time.

또한, 회전축의 하우징 내부에 연결되어 하우징의 저면과 중앙에 횡방향의 2단으로 설치되는 임펠러를 회전축에서 멀어질수록 높이가 낮아지는 경사형 사각 사다리꼴 형태로 각각 3~4개씩 설치하고, 임펠러의 회전축과 결합되지 않은 타측 상부에는 위로갈수록 폭이 좁아지는 경사형 사각 사다리꼴 수직암을 상기 회전축과 수평을 이루게끔 설치하여, 구동모터 회전시 원심력에 의해 하우징 가열면적에 함수율이 높은 찌꺼기가 우선적으로 밀착 부착되며 하우징 내벽에 골고루 퍼져서 부착 및 건조, 이탈현상을 반복하여 찌꺼기의 함수율을 저감시키는 하수 및 분뇨, 음식물 찌꺼기 건조장치에 관한 것이다.
In addition, three to four impellers, which are connected to the inside of the housing of the rotating shaft and installed in the transverse two stages at the bottom and the center of the housing, are lowered as the distance from the rotating shaft. On the other side that is not combined with the rotating shaft, an inclined rectangular trapezoidal vertical arm, which becomes narrower upward, is installed to be horizontal with the rotating shaft, so that the residue having high moisture content adheres to the housing heating area preferentially by the centrifugal force when the drive motor rotates. The present invention relates to sewage, manure and food waste drying apparatus which is attached and spreads evenly on the inner wall of the housing to reduce the moisture content of the waste by repeatedly attaching, drying and leaving the phenomenon.

최근 하수 및 분뇨, 음식물 찌꺼기를 해양투기하여 처리하는 방식은 정부에서도 금지되고 있고, 매립 등은 심각한 환경오염을 유발하기 때문에 찌꺼기를 자원으로 재활용하는 방안이 개발되고 있다.Recently, the method of disposing of sewage, manure and food wastes by ocean dumping is prohibited by the government, and landfills are causing serious environmental pollution.

재활용 방안으로는 하수 및 분뇨, 음식물 찌꺼기를 건조 및 발효, 후숙 공정을 마친 후 부숙토 및 토양 개량재로 만들어 토양 오염을 방지하고, 탄화 등으로 재이용하는 방법들이 제시되고 있다. 이러한 재활용 공정 중 가장 핵심이 되는 부분은 하수 및 분뇨, 음식물 찌꺼기를 일정한 함수율 이하로 건조시켜서 후속공정인 발효공정이 원활하게 이루어지도록 함에 있다.As a recycling method, methods for drying and fermenting sewage and manure, food wastes, and ripening processes are used to improve soil soil and improve soil pollution, and reuse them as carbonization. The most important part of this recycling process is to dry the sewage, manure and food waste below a certain moisture content to facilitate the subsequent fermentation process.

종래의 하수 및 분뇨, 음식물 찌꺼기의 건조장치는 외부 보일러에 의해 열이나 스팀을 하수 및 분뇨, 음식물 찌꺼기를 건조시키는 하우징 내부로 직접 투입하고 가열하여 건조시키거나 또는 찌꺼기의 유기물 세포에 전기를 투입하여 세포에서 수분을 분리하고 탈수하는 전기침투식 방법이 사용되었다.The conventional apparatus for drying sewage, manure and food waste is put heat or steam directly into a housing for drying sewage, manure and food waste by an external boiler and dried by heating or by putting electricity into organic cells of the waste. An electropenetrating method was used to separate and dehydrate the cells.

그러나, 종래의 기술은 보일러에서 발생하는 열이나 스팀을 직접 건조기의 하우징 내부로 투입하기 때문에 보일러의 동력 외에도 펌프 등 보조수단을 통해 열이나 스팀을 전달시켜야 해 추가적인 동력소모가 발생하여 연료비용이 과다하게 소요되며, 건조공정 때에 사용되는 스팀을 외부로 배출시킬때에 외부공기가 하우징내로 유입되어 증가된 악취가스의 처리비용이 증가하여 비경제적이며, 건조시 하우징 내부로 유입되는 공기와 악취가스의 이물질 등이 찌꺼기에 달라붙어 처리하는데 비효율적이다.However, in the conventional technology, since heat or steam generated from a boiler is directly injected into a housing of a dryer, heat or steam must be transferred through auxiliary means such as a pump in addition to the power of the boiler, resulting in additional power consumption and excessive fuel cost. When the steam used in the drying process is discharged to the outside, the outside air flows into the housing and the treatment cost of the increased malodorous gas increases, which is uneconomical. It is inefficient to treat foreign matter sticking to the residue.

상기와 같은 종래의 하수 및 분뇨, 음식물 찌꺼기의 처리방식을 개선하여 열매체를 이용한 간접 처리방식을 거치고 열매체가 순환하여 열소비를 줄이는 열매체 순환형 건조양생장치가 특허 제 10-1077495호, 제 10-0976378호에 개시되어 있으나, 상기의 특허는 내부의 스크류에 열을 전달 및 공급해야 하므로 공정이 복잡하고 건조시 외부로부터 유입되는 공기로 인한 악취가스의 발생량이 높을 뿐만아니라, 하우징 내부에 설치된 스크류와 스팀을 직접 하우징 내부에 투입하므로 찌꺼기가 수분과 완전히 분리가 되지 않고 들러붙는 경우가 많아 종래의 하수 및 분뇨, 음식물 찌꺼기의 처리방식을 완전하게 개선하였다고 보기는 어렵다.
The heat medium circulation drying curing device which improves the conventional method of treating sewage, manure and food waste as described above, undergoes an indirect treatment method using a heat medium, and heat medium is circulated to reduce heat consumption. Patent Nos. 10-1077495, No. 10- 0976378, but the above-mentioned patent is required to transfer and supply heat to the internal screw, the process is complicated, and the amount of odor gas generated by the air flowing from the outside during drying, as well as the screw installed inside the housing Since steam is directly injected into the housing, it is difficult to completely improve the treatment method of conventional sewage, manure and food waste because the residue is often stuck to the water without being completely separated from the water.

Equipped with a heating pad filled with a heating cable that is wound at regular intervals with a special insulating material to increase the effect of heat transfer to the inner wall of the housing, and a heating material with a thermal insulation casing treatment outside the heating pad to maintain the heating temperature for a long time, increasing efficiency Transverse to the bottom and center inside the housing of the rotating shaft Three to four impellers installed in two stages of incense are installed in inclined rectangular trapezoidal shape, the height of which decreases as it moves away from the rotating shaft, and the inclined type that becomes narrower upwards on the other side that is not combined with the rotating shaft of the impeller. By installing the rectangular trapezoidal vertical arm to be parallel to the rotation axis, the residue with high moisture content is attached to the housing heating area preferentially by centrifugal force when the drive motor rotates, and it spreads evenly on the inner wall of the housing to repeat the attachment, drying, and detachment phenomenon. The main purpose is to reduce the water content of the residue.
