슬러지 건조용 열교환 나선구조를 갖는 2중 드럼{DOUBLE DRUM HAVING HEAT EXCHANGING SPIRAL STRUCTURE FOR DRYING SLUDGE}DOUBLE DRUM HAVING HEAT EXCHANGING SPIRAL STRUCTURE FOR DRYING SLUDGE}

본 고안은 슬러지 건조용 열교환 나선구조를 갖는 2중 드럼에 관한 것으로 상세하게는 각종의 하수처리장치나 정수장치 또는 산업폐수 정화장치 등에서 발생되는 수분을 포함한 반죽 상태의 슬러지를 건조시키는 장치에 있어서의 요부인 건조 드럼의 열교환 구조를 2중 통체에 의한 나선 구조에 의하여 열교환 면적을 극대화하여 건조 효율을 증대 시킬 수 있도록 한 것이다.The present invention relates to a double drum having a heat exchange spiral structure for drying sludge, and in particular, a main part of an apparatus for drying a sludge in a kneaded state containing water generated from various sewage treatment systems, water purifiers, or industrial wastewater purifiers. The heat exchange structure of the phosphorus drying drum is to increase the drying efficiency by maximizing the heat exchange area by the spiral structure by the double cylinder.

주지하는 바와 같이 산업화 과정에서 생활하수는 물론 각종 공장폐수 등 수질오염이 극심하여 환경 문제가 사회적 관심사로 부각되면서 오폐수 처리장치의 설치를 의무화 하고 있는 바, 폐수를 처리하게되는 과정에서 막대한 량의 슬러지가 발생하게 된다.As it is well known, due to the serious water pollution such as living sewage as well as various factory wastewater in the industrialization process, environmental problems are emerging as a social concern, and mandatory installation of wastewater treatment equipment, and a large amount of sludge in the process of treating wastewater. Will occur.

슬러지는 수분을 포함한 겔 상태이므로 이를 그대로 처리할 수 없기 때문에 통상은 건조장치를 통하여 건조시켜 분말 상태로 만들어 매립지 등의 매립재로 사용하게 된다.Since the sludge cannot be treated as it is a gel state containing water, it is usually dried through a drying apparatus to make a powder state to be used as a landfill material such as landfill.

통상의 슬러지 처리장치를 도 1 및 도 2에 의하여 개략 설명하면 다음과 같다.A general sludge treatment apparatus will be described below with reference to FIGS. 1 and 2.

폐수 처리장치에서 침전 발생되는 슬러지는 벨트 프레스 또는 필터 프레스에 의한 1차 수분 제거장치(1)에 의하여 수분을 어느정도 제거한 상태에서 건조 장치로 이송시켜 건조하게 되는 데, 흡입기(2)를 통하여 흡입시켜 드레인 파이프(3)를 통하여 대향 회전하는 한 쌍의 건조드럼(4a)(4b) 상부측으로 분리 공급된다.The sludge generated by sedimentation in the wastewater treatment device is dried by being transferred to a drying device in a state where water is removed to some extent by the primary water removal device 1 by a belt press or a filter press. It is separately supplied to the upper side of a pair of drying drums 4a and 4b which are opposed to rotate through the drain pipe 3.

건조드럼(4a)(4b)의 내부에는 스팀, 가온 액체, 열풍 등을 공급 통과 순환시키면서 드럼을 가열하게 되며, 상부 측에는 한쌍 씩의 롤러가 장착되는 데, 외측에 장착되는 롤러는 흘러내림 방지롤러(5a)로써, 드럼과 밀착 상태로 반대 회전하게 됨으로서 공급되는 슬러지가 외부로 흘러내리지 않도록 하는 역할을 하게 되며, 각 내측에 장착되는 롤러는 스페이스 롤러(5b)로써 드럼과 약간의 간격을 두고 반대 회전하게 됨으로서 설정된 간격만큼의 두께로 슬러지를 드럼의 표면에 부착 시켜 공급하게 되며, 드럼 둘레에 막으로 입혀져 공급되는 슬러지는 건조되면서 회전하다가 안쪽으로 대향 회전하는 한 쌍의 건조드럼(4a)(4b) 맞물림에 의하여 분쇄 되면서 낙하하게 되고, 건조되어 낙하된 슬러지 분말은 이송스크류 컨베이어(6a)(6b)에 의하여 외부로 배출되어 야적 상태로 쌓이게 된다.Inside the drying drums 4a and 4b, the drum is heated while supplying and circulating steam, heated liquid, hot air, etc., and a pair of rollers are mounted on the upper side, and the rollers mounted on the outside are anti-flow rollers. As 5a, the sludge supplied is rotated in close contact with the drum to prevent the sludge supplied from flowing to the outside, and the rollers mounted on each inner side are spaced apart from the drum by space rollers 5b. As it rotates, the sludge is attached to the surface of the drum at a thickness equal to a predetermined interval, and the sludge supplied as a film around the drum is dried and rotated while being rotated inward to face a pair of drying drums 4a and 4b. ) Sludge powder that falls while being crushed by engagement, and dried and dropped sludge powder is discharged to the outside by the transfer screw conveyor (6a) (6b) It is accumulated into enemy state.

한편, 드럼에서의 슬러지 건조 과정과 컨베이어 이송과정에서의 잔류 수분 증발에 따른 증기를 제거하기 위하여 드럼의 상부측과 컨베이어의 상부측에는 각각 증기 배출 갓(7a)(7b)이 설치되어 있으며, 포집된 증기는 증기 배출 파이프(8)를 통하여 외부로 유도 배출 할 수 있도록 되어 있다.On the other hand, in order to remove the steam due to evaporation of residual water in the drum drying process and the conveying process of the drum, steam discharge caps 7a and 7b are respectively installed on the upper side of the drum and the upper side of the conveyor. The steam can be induced and discharged to the outside through the steam discharge pipe (8).

이와 같은 슬러지 건조 장치에 있어서의 종래 건조드럼의 구조는 도 5에서 도시한 바와 같이 건조드럼(4a)(4b)의 내면에 4각 또는 파이프 형의 가열관(9a)(9b)을 스크류 형으로 둘러 가열 매체를 통과 시킴으로써 드럼을 가열할 수 있도록 하였던바, 이와 같은 종래 구조는 드럼의 내부 면에 용접 설치하여야 하므로 제작이 매우 까다롭고 어려운 문제점과 열매체가 통과하는 가열관(9a)(9b) 부위는 고온으로 되나 가열관이 없는 공간부는 열이 미약하여 고른 열전달이 불가능 하므로 드럼 전체적으로 피복되어 건조되는 슬러지를 골고루 건조시키에 미흡한 결점이 있었던 것이다.The structure of the conventional drying drum in such a sludge drying apparatus has a quadrangular or pipe-type heating tube 9a, 9b screwed on the inner surface of the drying drum 4a, 4b as shown in FIG. The drum was heated to be heated by passing a heating medium, and this conventional structure has to be welded to the inner surface of the drum, which is very difficult and difficult to manufacture, and the heating tubes 9a and 9b through which the heat medium passes. The high temperature, but the space without the heating tube is not enough heat transfer because the heat is weak, there was a deficiency in evenly drying the sludge covered and dried throughout the drum.

본 고안은 이와 같은 제결점을 감안 해결하기 위하여 안출한 것으로서, 드럼의 둘레 통체 구조를 2중 통체 구조로 하고 그 공간부에 스크류 형의 열매체 가이드라인을 형성하게 됨으로서 드럼의 외부를 전체적으로 고르게 가열하여 건조 효율을 극대화 시킬 수 있도록 한 것이다.The present invention has been devised to solve the above-mentioned drawbacks, and the drum's circumferential cylinder structure is made into a double cylinder structure and a screw-type heat medium guideline is formed in the space to uniformly heat the outside of the drum. It is to maximize the drying efficiency.

The heat medium guide line 12 is vertically formed to be a partition wall, and a heat medium injection hole 14a and a discharge hole 14b are formed on the centers of the mounting shafts 13a and 13b, which are protrudingly installed at each center of both sides. In addition, the upper and lower portions of the liver are connected to the inner side, and the injection connection pipe 15a and the discharge connection pipe 15b are installed to connect the space 11 around the drum.

이와 같이 구성된 본 고안은 슬러지 건조장치에 대향 회전되게 하여 한 쌍이 설치되며, 일측의 열매체 주입공(14a)과 주입 연결 파이프(15a)를 통하여 스팀, 가온 액체, 열풍 등의 열매체가 주입되어 건조드럼(4c)의 둘레를 나선형으로 공간없이 전체적으로 회류하면서 가열하게 되고, 배출 연결 파이프(15b)와 배출공(14b)을 통하여 빠져나가 가열기에 의하여 재가열되어 순환을 반복하게 됨으로써 드럼 둘레에 얇게 피막되는 슬러지를 건조시켜 분말화 하게 되는 것이다.The present invention constituted as described above has a pair installed so as to be opposed to the sludge drying apparatus, and heat medium such as steam, heated liquid and hot air is injected through a heat medium injection hole 14a and an injection connection pipe 15a on one side to dry the drum. Sludge which is heated around the circumference (4c) in a spiral shape without the space as a whole, exits through the discharge connection pipe 15b and the discharge hole 14b, is reheated by the heater, and is repeatedly cycled to form a thin film around the drum. It will be dried to powder.

상기한 바와 같은 본 고안은 드럼의 구조가 2중 통체 구조로 되고 그 공간부에는 나선형으로 열매체 가이드라인이 설치되어 전체적으로 열매체를 회류 유도하게 됨으로서 드럼의 외면 전체적으로 공간없이 일정한 가열상태가 유지되어 열 손실없이 건조 효율을 극대화 시킬 수 있게 되며, 슬러지의 완전 건조를 실현할 수 있게되는 우수한 효과가 있는 것이다.The present invention as described above, the drum structure is a double-cylindrical structure and the heat medium is installed spirally in the space portion to guide the heat medium through the entire heat flow to maintain a constant heating state without space on the entire outer surface of the drum heat loss Without being able to maximize the drying efficiency, there is an excellent effect that can realize the complete drying of the sludge.
