본 고안은 젖은 폐기물이 혼합되어 배출되고 있는 다습한 폐기물을 신속하게 탈수, 건조처리를 위한 증기침투 직접 가열식 다습 폐기물의 탈수장치에 관한 것이다.The present invention relates to a steam infiltration direct heating humidifying dewatering device for quickly dewatering and drying the humid waste discharged by mixing the wet waste.

현대사회의 생활 쓰레기는 산업발전에 따른 물질의 풍요함에 비례하여 엄청난 분량으로 배출되어진다.Household waste in modern society is produced in huge quantities in proportion to the abundance of materials in accordance with industrial development.

특히 대도시의 복잡한 생활속에서 발생하는 생활폐품, 쓰레기 등이 서로 분리되지 않은채 섞여 수거됨으로해서 처리에 문제점으로 대두되고 있다.In particular, household waste, garbage, etc., which occur in the complex life of a large city, are collected and mixed without being separated from each other.

종래에는 일정장소에 수거 매립하는 방법에 의하여 다량의 쓰레기를 매립 처리하여 왔으나, 심한 악취로 인한 주변환경 오염과, 지하수오염으로 생활용수 활용에 문제가 있으며 또한 매일같이 엄청난 양의 쓸레기가 배출됨으로써 매립처리의 한계에 이르고 있다.Conventionally, a large amount of garbage has been disposed of by landfilling in a certain place. However, there is a problem in using living water due to environmental pollution caused by severe odors and groundwater pollution. The limit of landfilling has been reached.

이와 같은 문제점이 있어 최근에는 소각방식에 의해 쓰레기를 처리하는 방식을 통하여 폐열을 이용한 난방등 산업상의 유용한 에너지원으로도 활용하며 매립처리방법의 여러가지 문제점들을 해결하고자 다양한 소각장치들이 제안되고 있다.Recently, various incinerators have been proposed to solve various problems of landfill methods by utilizing them as industrial useful energy sources such as heating using waste heat through the method of treating waste by incineration.

그러나 소각로에 의한 소각처리방식의 문제점으로는 젖은 쓰레기와 마른 쓰레기가 서로 섞여 수거 처리되는 관계로 연소시 완전연소를 시킬 수 없어 많은 공해 물질을 배출시킴으로서 새로운 공해요인으로 제기되고 있다.However, the problem of the incineration method by incinerators has been raised as a new pollutant by discharging a lot of pollutants because it can not be completely burned during combustion because the wet and dry waste is mixed with each other and collected.

이와 같은 문제점을 해소하기 위하여 종래에는 소각로 자체에서 젖은 쓰레기를 가열 건조시키면서 소각시키는 다양한 소각장치들이 개발되고 있으나 이는 처리능력 저하로 다량의 폐기물이 발생되는 현상황의 실정에서 부적합하며 젖은 폐기물의 강제연소시 불완전 연소로 인한 공해가스 물질 배출은 감소되지 않고 있다.In order to solve such a problem, various incinerators have been developed to incinerate while drying wet waste in the incinerator itself, but this is inappropriate in the situation where a large amount of waste is generated due to a decrease in processing capacity and forced combustion of wet waste. Pollutant gas emissions from incomplete combustion have not been reduced.

따라서 젖은 폐기물을 연소시키기 용이하도록 수분을 제거하기 위한 수단이 요구된다.There is therefore a need for means to remove moisture to facilitate combustion of wet waste.

특히 산업현장의 산업 부산물로 발생되는 다량의 슬러지의 경우 함수량이 매우 많아 이를 처리하는데 매우 커다란 난점으로 남아 있었다.In particular, a large amount of sludge generated as an industrial by-product of the industrial site has a very high water content, which remains a very difficult problem to deal with.

상기의 여러가지 문제점을 해소하기 위하여 본 출원인은 93. 3. 23 일자 선출원 실용신안등록출원 제4332호(명칭 : 다습폐기물의 가열탈수장치)를 출원한 바 있다.In order to solve the various problems described above, the present applicant has filed a Utility Model Registration Application No. 4332 (name: heating dehydration device of high humidity waste) dated March 23, 2011.

첨부도면 제3도에 도시된 바와 같이 구동모터(12)에 의해 구동되는 스크류(11)와 다수의 탈수공(21)이 천공 설치된 폐기물처리관(20)에 의한 압착부로 구성되며, 상기 스크류(11)의 중심축인 이송축(10)은 파이프형상으로서 외부로부터 고열의 증기가 투입되어 압착되는 폐기물의 내부를 가열시키며, 또한 폐기물처리관(20)의 외측을 둘러 싸고 있는 외부가열장치부(30)에 의하여 폐기물에 열을 가함으로써 다습한 폐기물을 가열 압착 탈수시키도록 한 것이다.As shown in FIG. 3, the screw 11 driven by the drive motor 12 and the plurality of dehydration holes 21 are formed by a crimping portion by a waste treatment pipe 20 in which the screw is drilled. 11, the feed shaft 10, which is the central axis of the pipe, has a pipe shape, and heats the inside of the waste to which the high-heat steam is injected from the outside and is compressed, and also surrounds the outside of the waste treatment pipe 20. By heating the wastes in accordance with 30), the wet wastes are heated, compressed and dehydrated.

즉 상기의 선출원은 이송축(10)과 외부가열장치부(30)에 의하여 폐기물에 열을 공급하는 것으로서 일단 이송축(10)과 외부가열장치부(30)의 외부표면이 가열된 상태에서 그 사이를 통하는 폐기물을 가열하는 간접가열 방식이다.That is, the above-mentioned source is to supply heat to the waste by the feed shaft 10 and the external heating unit 30, once the external surface of the feed shaft 10 and the external heating unit 30 is heated. It is an indirect heating method that heats waste through.

상기의 선출원은 다습한 폐기물을 연속적으로 골고루 가열시키면서 압착하여 수분을 제거시킬 수 있도록한 다습폐기물의 가열탈수장치로서 상당한 효과를 나타내고는 있으나 특히 산업폐기물의 다습 슬러지의 처리시에는 가열 효과가 약간 미흡함이 있었다.The above-mentioned application shows a significant effect as a dehydration device for the high-density waste, which can be compressed to remove moisture by uniformly heating the humid waste continuously, but the heating effect is slightly inferior in the treatment of the humidified sludge of industrial waste. There was this.

즉 처리장치내에 투입된 폐기물의 양이 많을 경우 슬러지 층이 두꺼워 상기와 같은 표면 복사열에 의한 간접가열방식은 열전달 효율이 낮고 시간이 많이 걸려 이에 따른 고율의 탈수율은 얻는데 한계가 있었고 슬러지배출부의 구조상 압착 탈수된 슬러지가 용이하게 배출되지 못하는 문제점이 있었다.That is, when the amount of waste put into the treatment device is large, the sludge layer is thick, so the indirect heating method by surface radiant heat as described above has a low heat transfer efficiency and takes a lot of time, so it is difficult to obtain a high rate of dehydration rate. There was a problem that the dewatered sludge is not easily discharged.

이와 같은 문제점을 개선하기 위하여 본 고안에서는 탈수장치내에 투입되는 슬러지와 고열의 증기가 직접적으로 열교환이 이루어지도록 하기 위하여 슬러지 투입부와 압착장치부의 스크류우 중심축을 통하여 슬러지 자체에 직접적으로 고열의 증기가 직접 접촉되어 가열기능을 배가시키고 탈수된 슬러지의 배출이 용이하도록 개량된 증기투입 직접 가열식 폐기물 탈수장치를 제공하는데 그 목적이 있다.In order to improve such a problem, in the present invention, high-temperature steam is directly applied to the sludge through the screw shaft central axis of the sludge inlet and the pressurizing unit in order to directly exchange heat with the sludge and the high-heat steam. It is an object of the present invention to provide an improved steam injection direct heating waste dewatering device that is capable of directly contacting to double the heating function and to facilitate the discharge of dewatered sludge.

상기의 목적을 달성하기 위하여 본 고안에서는 고온·고압의 증기를 슬러지 투입부에 별도의 증기 공급장치를 구비하고 탈수 장치내의 투입된 슬러지의 이송 및 압착탈수 기능을 하는 스크류우의 파이프형 이송축상에도 다수의 증기분출공을 천공 설치하여 투입된 슬러지에 직접적으로 뜨거운 증기가 접촉되도록 함으로써 직접가열에 의한 열효율을 향상 및 탈수율을 배가시키도록 하며 슬러지배출부의 압축조절판을 조절레버에 의해 간격조절이 용이하도록 한 것을 특징으로 한다.In order to achieve the above object, in the present invention, a high temperature and high pressure steam has a separate steam supply unit at a sludge inlet unit, and a plurality of screw-type feed shafts are also provided on the pipe-type feed shaft of the screw for transporting and compressing dewatering of sludge introduced into the dewatering unit. Hot steam is directly contacted with the sludge injected by installing the steam ejection hole to improve the thermal efficiency by direct heating and to increase the dehydration rate, and the compression control plate of the sludge discharge part is easily adjusted by the control lever.
