본 발명은 폐기물 및 재활용가능자원 전처리시설(MBT, Mechanical Biological Treatment)과 가공연료(RDF, Refuse Derived Fuel) 제조시설의 사이클론(cyclone)식 기류건조장치에 관한 것으로, 사이클론식 기류건조장치에 전열선을 설치하여 가열함으로써 건조효과를 향상시킨 것이다.The present invention relates to a cyclone airflow drying apparatus for a waste and recyclable resource pretreatment facility (MBT) and a refuel derived fuel (RDF) manufacturing facility. By installing and heating, the drying effect is improved.

폐기물 및 재활용가능자원 전처리시설(MBT, Mechanical Biological Treatment)이란 각종 산업폐기물, 생활폐기물 및 재활용가능자원을 수집, 선별, 분쇄 및 건조 등의 공정을 통하여 처리함으로써 이후의 소각, 매립 및 재활용 공정의 용이한 실시가 가능하도록 하는 시설을 말하며, 폐기물 및 재활용가능자원 가공연료(RDF, Refuse Derived Fuel) 제조시설이란 전처리과정을 거친 폐기물 및 재활용가능자원을 건조, 탄화 및 고형화 등의 공정을 거쳐 연료화하는 시설로서 일종의 재활용시설이라 할 수 있다.Waste and Recyclable Resource Pretreatment Facility (MBT) is a collection, sorting, crushing and drying process of industrial wastes, household wastes, and recyclable resources, which facilitates subsequent incineration, landfill, and recycling processes. It refers to a facility that enables one implementation, and a facility that manufactures waste and Refuse Derived Fuel (RDF) is a facility that fuels waste and recyclable resources that have been pretreated through drying, carbonization, and solidification. It is a kind of recycling facility.

도 1은 전술한 전처리시설 또는 가공연료 제조시설 중 슬러지 건조설비를 발췌한 모식도로서, 도시된 예에는 건조장치로서 사이클론(cyclone)식 기류건조장치가 적용되어 있다.Figure 1 is a schematic diagram of the sludge drying equipment of the pre-treatment or processing fuel manufacturing facilities described above, the cyclone (cyclone) air flow drying device is applied to the illustrated example.

하, 폐수처리시설, 어패류 등의 함수율이 높은 식품공업 부산물 처리시설 및 음식물쓰레기 처리시설 등에서 발생되는 슬러지(sludge)는 도 1에서와 같은 건조설비가 포함된 전처리시설 또는 가공연료 제조시설을 통하여 건조되어 폐기되거나 고형연료로 제조된다.Sludge generated in food industry by-product processing facilities and food waste treatment facilities with high moisture content such as wastewater treatment facilities, fish and shellfish, etc. is dried through a pretreatment facility or a processing fuel manufacturing facility including a drying facility as shown in FIG. It is either disposed of or made of solid fuel.

도 1의 사이클론식 기류건조장치는 도 2 및 도 3과 같이 상광하협(上廣下狹)의 원추형 관체(管體)로서, 접선방향의 유입관(111)과 중심부의 배기관(112)이 설치된 원통부(110)와 하단에 배출관(121)이 형성된 원추부(120)가 결합되어 구성되며, 슬러지와 같은 고액혼합물이 기류와 혼합되어 일종의 분무(噴霧)상태로 유입관(111)을 통하여 유입되면 도 2에서와 같이, 하향 선회류를 형성하면서 건조된 고형물은 배출관(121)을 통하여 배출되고 증발된 수분은 배기관(112)을 통하여 배기되는 방식으로 작동된다.The cyclone-type airflow drying apparatus of FIG. 1 is a conical tube of an upper and lower strait as shown in FIGS. 2 and 3, and includes a tangential inlet pipe 111 and an exhaust pipe 112 in a central portion thereof. Cylindrical portion 110 and the conical portion 120 formed with the discharge pipe 121 formed at the bottom is coupled, and the solid-liquid mixture such as sludge is mixed with the airflow flows through the inlet pipe 111 in a kind of spray (噴霧) state 2, the solids dried while forming the downward swirl flow are discharged through the discharge pipe 121 and the evaporated water is discharged through the exhaust pipe 112.

이러한 사이클론식 기류건조장치는 건조대상 혼합물을 가열된 기류와 혼합하여 투입함으로써, 건조효과를 배가하게 되는데, 기류의 유입 관로에 별도의 가열수단을 설치하거나, 외기를 흡기하여 관로에 인가하는 펌프의 작동열을 통하여 기류를 가열하는 등의 방식으로 가열된 상태의 기류를 생성하게 된다.The cyclone-type airflow drying apparatus doubles the drying effect by mixing the drying target mixture with the heated airflow, and installs a separate heating means in the inflow pipe of the airflow or intakes outside air to apply it to the pipe. The heat of the air is generated in such a manner as to heat the air flow through the operating heat.

이렇듯, 종래의 사이클론식 기류건조장치는 건조효과를 확보하기 위한 가열수단으로서, 유입되는 기류를 가열하는 방식을 취하고 있으며, 일단 유입된 기류 및 건조대상 혼합물은 하향 선회류를 형성하며 건조되는 과정에서 냉각될 수 밖에 없는 문제점이 있었다.As such, the conventional cyclone-type airflow drying device is a heating means for securing a drying effect, and takes a method of heating the incoming airflow, and once the introduced airflow and the mixture to be dried form a downward swirl flow in the process of drying. There was a problem that can not be cooled.

한편, 페이스트(paste) 상태의 건조대상물을 적재한 상태에서 내부 교반 및 가열을 통하여 건조하는 가열식 건조장치의 경우, 건조장치를 격리된 챔버(chamber)에 수납하고, 챔버에 증기를 투입하는 방식으로 가열하고 있으나, 유지관리가 어렵고, 가열효율이 낮을 뿐 아니라, 고온을 얻을 수 없으며, 균일한 가열효과를 기대할 수도 없는 문제점이 있었다.On the other hand, in the case of a heated drying apparatus which is dried by internal stirring and heating in a state where a dry object to be pasted is loaded, the drying apparatus is stored in an isolated chamber and steam is introduced into the chamber. Although heating, it is difficult to maintain, low heating efficiency, high temperature can not be obtained, there was a problem that can not expect a uniform heating effect.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 상부에 유입관(111) 및 배기관(112)이 구성된 원통부(110)와, 하단에 배출관(121)이 구성된 원추부(120)로 이루어진 사이클론(cyclone)식 기류건조장치에 있어서, 원추부(120)를 감싸는 전열선(130)이 설치되어, 전원(139)이 인가됨에 따라 기류건조장치를 가열하며, 전열선(130)이 설치된 원추부(120)의 위주면에는 원추부(120) 및 전열선(130)을 감싸는 단열층(131)이 설치되어 외부로의 열손실을 최소화할 수 있도록 한 것이다.The present invention was devised in view of the above-described problems, and includes a cyclone portion 110 having an inlet pipe 111 and an exhaust pipe 112 formed at an upper portion thereof, and a cone portion 120 having a discharge pipe 121 formed at a lower portion thereof. In the cyclone type airflow drying apparatus, a heating wire 130 surrounding the cone portion 120 is installed, and heats the airflow drying apparatus as the power source 139 is applied, and the cone portion 120 in which the heating wire 130 is installed. On the circumferential surface of the) is a heat insulating layer 131 surrounding the cone portion 120 and the heating wire 130 is installed to minimize the heat loss to the outside.

본 발명을 통하여, 사이클론식 기류건조장치의 건조효율을 향상시킬 수 있으며, 시설규모대비 처리용량을 확보할 수 있어 전체 시설의 소형화가 가능하고, 이로써 전처리시설 및 가공연료 제조시설의 건설비용을 절감하는 효과를 얻을 수 있다.Through the present invention, it is possible to improve the drying efficiency of the cyclone-type airflow drying apparatus, to secure the processing capacity compared to the size of the facility, and to miniaturize the entire facility, thereby reducing the construction cost of the pretreatment facility and the processing fuel manufacturing facility. You can get the effect.
