본 발명은 소각장치에서 발생하는 폐열(스팀)을 이용하는 슬러지 건조장치에 관한 것으로서, 좀더 상세하게는 하수관로 및 하수 종말 처리장 등에서 발생하는 하수 슬러지 및 각종 함수성 슬러지와 음식물 쓰레기 등과 같은 대상물을 병합처리하기 위한 것으로 대상물을 건조함과 동시에 파쇄하여 건조율을 높일 수 있도록 함과 아울러 건조 대상물의 부피를 최소화시켜줄 수 있도록 한 슬러지 건조장치를 제공하기 위한 것이다.The present invention relates to a sludge drying apparatus using waste heat (steam) generated in an incinerator, and more specifically, to process sewage sludge generated in sewage pipes and sewage terminal treatment plants, and various objects such as water-containing sludge and food waste. The purpose is to provide a sludge drying apparatus to minimize the volume of the drying object while increasing the drying rate by drying and crushing the object at the same time.

하수 종말 처리장 등에서 발생하는 하수 슬러지 및 각종 함수성 슬러지와 같은 폐기물은 그 처리가 매우 고심스러운 것인바, 종래에는 해양투기나 소각 등의 방법을 이용하여 슬러지를 처리하여 왔다.Wastes such as sewage sludge and various functional sludges generated in the sewage terminal treatment plant, etc. are very difficult to treat, and conventionally, sludges have been treated using methods such as ocean dumping and incineration.

그러나, 하수 슬러지 및 각종 함수성 슬러지는 다량의 수분을 함유(평균 함수율 80%)하고 있을 뿐만 아니라 그 부피가 크기 때문에 소각에 상당한 비용이 발생하고 다량의 침출수에 대한 처리문제가 지적되고 있으며, 슬러지의 소각과정에서 환경에 치명적인 다량의 다이옥신이 발생하기 때문에 환경에 악영향을 끼치게 된다는 등의 폐단이 지적되고 있다.However, sewage sludge and various functional sludges contain a large amount of water (average moisture content of 80%), and because of their large volume, incineration has a considerable cost, and a problem of treating a large amount of leachate has been pointed out. It is pointed out that a large amount of dioxins, which are fatal to the environment, occur during the incineration process, which adversely affects the environment.

또한, 환경오염 문제로 인해 하수 슬러지의 해양투기는 제도적으로 금지될 것이어서 슬러지의 처리에 매립 등의 방안이 검토될 수 있으나 슬러지를 직접 매립할 경우에는 부피가 문제될 뿐만 아니라 다량의 침출수가 지하로 유입되어 상당한 환경오염의 문제를 야기할 수 있는 것인바, 슬러지에 대한 적절하고도 효율적인 처리방안이 절실하게 요구되고 있다.In addition, due to environmental pollution, sewage sludge's ocean dumping will be systematically prohibited. Therefore, landfilling can be considered for the treatment of sludge. Since it can be introduced to cause significant environmental pollution problems, there is an urgent need for proper and efficient treatment of sludge.

그에 따라서 슬러지를 건조하여 함수율을 떨어트리기 위한 장비가 안출되어 사용되고 있는데, 종래의 건조 장비는 유류나 가스 등의 연소원을 이용하여 하수 슬러지를 건조시키는 장비가 주류를 이루고 있다.Accordingly, the equipment for drying the sludge to reduce the moisture content is devised and used, the conventional drying equipment is a mainstream equipment for drying the sewage sludge using a combustion source such as oil or gas.

상기한 종래의 건조 장비는 슬러지를 단순건조하는 것으로, 덩어리진 상태의 슬러지에 대하여 균일하고 완전한 건조를 기대할 수 없을 뿐만 아니라 불완전 건조로 인해 슬러지의 부피를 줄일 수 없다는 등의 문제점이 지적되고 있다.The above-mentioned conventional drying equipment is a simple drying of the sludge, it is pointed out that problems such as not able to expect uniform and complete drying for the agglomerated sludge, and also can not reduce the volume of the sludge due to incomplete drying.

본 발명은 전술한 바와 같은 슬러지 처리체계에서 발생한 제반 문제점을 일소하기 위해 창출된 것으로서, 다량의 수분을 함유한 각종 슬러지는 물론 음식물 쓰레기 등에 대한 건조와 파쇄를 동시에 진행함으로써 슬러지 및 음식물 쓰레기 등에 대한 건조효율을 향상시킬 수 있도록 함과 아울러 슬러지 및 음식물 쓰레기의 함수율을 소망하는 수준으로 조절할 수 있도록 하고, 건조되는 슬러지 및 음식물 쓰레기의 부피를 최소화시켜 소각이나 매립에 따른 비용의 소요를 최소화시킬 수 있도록 하며, 또한, 기왕에 운용되고 있는 소각장치의 폐열(스팀)만으로 슬러지 및 음식물 쓰레기에 대한 건조작업을 진행할 수 있도록 하여 시스템의 운용에 따른 비 용을 최소화시킬 수 있도록 함에 기술적 과제의 주안점을 두고 완성하였다.The present invention was created in order to eliminate all the problems caused in the sludge treatment system as described above, by drying and crushing the various sludge containing a large amount of water as well as food waste and the like to dry the sludge and food waste, etc. In addition to improving efficiency, the water content of sludge and food waste can be adjusted to a desired level, and the volume of dry sludge and food waste can be minimized to minimize the cost of incineration or landfill. In addition, the construction of sludge and food waste can be carried out using only the waste heat (steam) of the incinerator, which has been operated in the past.

본 발명을 가동시킨 상태에서 투입호퍼(40)를 통해 슬러지나 음식물 쓰레기를 투입하면 파쇄실(20)로 낙하되고, 투입된 슬러지나 음식물 쓰레기는 서로 맞물리며 회전하는 파쇄 임팰러(21)의 패들(210) 사이에 개재되어 파쇄가 이루어지면서 이송되는데, 이때, 파쇄 임팰러(21)의 회전축(22)과 패들(210)이 고온의 스팀에 의해 가열된 상태이므로 슬러지나 음식물 쓰레기에 대한 파쇄와 건조가 동시에 이루어지는 것이며, 또한, 건조연통(31)을 통해 공급된 고온의 열풍이 파쇄실(20)을 가열시키므로 건조효율이 우수하게 유지되는 것이다.When the sludge or food waste is introduced through the input hopper 40 in the state of operating the present invention, the sludge or food waste is dropped into the shredding chamber 20, and the introduced sludge or food waste is interlocked with each other to rotate the paddle 210 of the shredding impeller 21. ) Is interposed between the crushed and conveyed, the rotational shaft 22 and the paddle 210 of the crushing impeller 21 is heated by high temperature steam, so the crushing and drying of the sludge or food waste It is made at the same time, and the high temperature hot air supplied through the drying barrel 31 heats the crushing chamber 20 so that the drying efficiency is excellently maintained.

그리고, 본 발명은 파쇄실(20)을 감싸고 있는 가열탱크(35)에도 고온의 스팀이 공급되고 있는 상태이므로, 파쇄실(20) 내부의 온도를 용이하게 상승시킬 수 있을 뿐만 아니라 파쇄실(20) 내부의 온도를 일정하게 유지할 수 있어 건조효율을 배가시킬 수 있는 것이다.In addition, since the present invention is a hot steam is also supplied to the heating tank 35 surrounding the crushing chamber 20, not only can the temperature inside the crushing chamber 20 be easily increased, but also the crushing chamber 20 The internal temperature can be kept constant, which can double the drying efficiency.

건조장치(10)에 의한 건조가 이루어지는 과정에서 슬러지 및 잔반의 건조물 은 맞물리며 회전하는 패들(210)의 작용에 의해 파쇄실(20)의 후방으로 점진적인 이송이 이루어져 배출관(25)을 통해 배출되는데, 이때, 배출되는 슬러지 및 잔반 건조물에 대한 함수율이 10% 이하로 유지되고 슬러지 및 잔반의 감량율은 80~90%에 이르게 된다.In the process of drying by the drying device 10, the sludge and the dry matter of the residue is interlocked and gradually transferred to the rear of the crushing chamber 20 by the action of the rotating paddle 210 is discharged through the discharge pipe 25, At this time, the water content of the discharged sludge and the residue dry matter is maintained at 10% or less, and the reduction ratio of the sludge and the residue reaches 80-90%.

한편, 본 발명은 파쇄실(20)로 공급된 열풍이 배기덕트(50)를 통해 배출되도록 한 것으로, 배기덕트(50)를 통해 배출되는 공기는 비중이 가벼운 부유물과 상당한 악취를 포함하고 있는바, 위 배출공기는 사이클론과 집진설비를 경유시켜 부유물을 걸러낸 다음 소각장치로 송출하여 악취를 제거할 수 있도록 함이 바람직하다.On the other hand, the present invention is to allow the hot air supplied to the crushing chamber 20 to be discharged through the exhaust duct 50, the air discharged through the exhaust duct 50 includes a light weight of the specific gravity and a significant odor bar In addition, it is preferable that the above exhaust air is filtered through the cyclone and the dust collector, and then sent to the incinerator to remove odors.

본 발명에서 제시하는 슬러지 건조장치는 각종 함수성 슬러지와 음식물 쓰레기를 병합처리할 수 있도록 한 것으로, 건조과정에서 덩어리 상태의 슬러지나 음식물 쓰레기를 파쇄하면서 건조하므로 균일하고 완전한 건조가 이루어질 수 있고, 건조물에 대한 함수율의 조절을 매우 용이하게 할 수 있을 뿐만 아니라 건조되는 슬러지나 음식물 쓰레기의 부피를 최소화시켜 소각이나 매립에 따른 비용을 획기적으로 절감할 수 있으며, 또한, 본 발명은 기왕에 운용되는 소각장치에서 발생한 폐열(스팀)만으로 슬러지 또는 음식물 쓰레기에 대한 건조작업이 가능하도록 함으로써 건조장치의 운용에 따른 비용을 최소화시켜 줄 수 있는 등 본 발명은 그 기대되는 효과가 매우 유익한 발명이다.The sludge drying apparatus proposed in the present invention is to be able to merge and process various kinds of functional sludge and food waste, and can be uniformly and completely dried because it is dried while crushing the sludge or food waste in the lump state during the drying process, dried Not only makes it very easy to control the water content, but also minimizes the volume of dried sludge or food waste, which can drastically reduce the cost of incineration or landfill. By allowing the drying operation for the sludge or food waste only by the generated waste heat (steam), the present invention can minimize the cost according to the operation of the drying apparatus.
