PURPOSE: A sludge dryer is provided, which is characterized in that sludge is dried by hot air through hot air generator(28). Thereby, sludge does not burn, and smoke does not occur. CONSTITUTION: When hot air generated by a hot air generator(28) flows into upper part of a tank(10) through a hot air pipe(28), temperature of hot air is 250°C. Hot air flows from upper part of the tank(10) to lower part of the tank(10) through holes(16)(26) of a rotating disk(15) and a fixed disk(25), and gaps(17). Thereby, sludge is dried. Water vapor occurred during drying goes to cyclone through an outlet(33), and goes to a cleaner(35). So, dust in sludge is removed, and pure water vapor is discharged. Supplementary hot air generator(30) is installed at lower part of tank(10), and blows hot air of 90°C into the tank(10). A water collecting tank(31) collects condensated water droplet.

본 발명은 슬러지 건조장치에 관한 것으로서, 더욱 상세하게는 폐수,하수용슬러지 및 산업용 슬러지를 하부로 이동시키면서 열풍으로 이를 건조하여 슬러지에 포함된 수분이 증발되어 슬러지가 건조되도록 함으로써, 슬러지를 건조하는 과정에서 오염물질의 배출이 최소화되고 또한 슬러지의 건조성이 향상되는 슬러지 건조장치에 관한 것이다.The present invention relates to a sludge drying apparatus, and more particularly, by drying it with hot air while moving wastewater, sewage sludge and industrial sludge to a lower portion to dry the sludge by evaporating moisture contained in the sludge. The present invention relates to a sludge drying apparatus which minimizes the discharge of pollutants in the process and also improves the dryness of the sludge.

일반적으로 슬러지 건조장치는 폐수 또는 하수에서 발생되는 슬러지를 건조하여 이의 부피를 줄여주는 장치이다. 종래 슬러지 건조장치는 슬러지를 버너로 직접 가열하는 방식을 사용하였다. 슬러지를 원통형의 본체 내부로 투입시켜 하부로이동되도록 하면서 이동중인 술러지를 버너로 가열하였다.In general, the sludge drying apparatus is a device that reduces the volume of the sludge is dried in the waste water or sewage. Conventional sludge drying apparatus used a method of directly heating the sludge with a burner. The sludge in motion was heated with a burner while the sludge was introduced into the cylindrical body to be moved downward.

그러나 종래의 건조장치는 슬러지가 버너로 직접 가열되기 때문에 가열도중에 타버리는 현상이 발생되며 타는 과정에서 유독성 매연이 발생되어 환경오염의 문제점이 제기되었다. 또한 종래의 건조장치는 건조하는 과정에서 슬러지를 잘게 부수는 파쇄기가 없기 때문에 덩어리진 슬러지를 건조하는데 시간이 많이 소요되어 열효율이 저하되는 등의 단점이 있었다.However, in the conventional drying apparatus, because the sludge is directly heated by the burner, the burning phenomenon occurs during the heating process, and toxic fumes are generated during the burning process. In addition, the conventional drying apparatus has a disadvantage in that it takes a long time to dry the agglomerated sludge because there is no crusher to crush the sludge in the drying process, the thermal efficiency is lowered.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 슬러지를 하부로 이동시키면서 이를 열풍으로 건조시킴으로써, 슬러지가 타지 않아 매연이 발생되지 않고 또한 슬러지를 잘게 부서 건조가 신속하게 이루어지도록한 슬러지 건조장치를 제공함에 있다The present invention was developed in view of the conventional problems, the object of the present invention is to move the sludge to the bottom while drying it by hot air, so that the sludge is not burned so that the smoke does not occur and also the sludge finely dry the department is made quickly To provide a sludge drying device

And the washing | cleaning machine 35 which secondary-collects the water vapor | steam from the cyclone 34 is provided. The wet craper 35 removes dust contained in the water vapor discharged by using the water sprayed from the nozzle.

이처럼 구성된 본 발명은 다음과 같이 작동된다. 먼저 모터(12)가 작동되면이와 벨트(13)로 연결된 풀리(14)가 회전되면서 회전축(11)이 일방향으로 회전된다. 회전축(11)이 회전되면 이의 외주면에 다단으로 결합된 회전디스크(15)와 회전막대(23)가 함께 회전되며 이와 동시에 투입스크류(10a)를 통하여 투입되는 슬러지가 탱크(10)의 내측 상단에 마련된 회전디스크(15)쪽으로 떨어진다. 그리고 열풍발생기(28)로부터 발생된 열풍이 열풍파이프(29)를 통하여 탱크(10)의 상단으로 공급되면 슬러지의 건조가 시작된다.The present invention thus constructed operates as follows. First, when the motor 12 is operated, the rotating shaft 11 is rotated in one direction while the pulley 14 connected to the belt 13 is rotated. When the rotating shaft 11 is rotated, the rotating disk 15 and the rotating rod 23 coupled to the outer circumferential surface of the rotary shaft 11 are rotated together, and at the same time, the sludge introduced through the feeding screw 10a is placed on the inner top of the tank 10. It falls toward the provided rotating disk 15. When the hot air generated from the hot wind generator 28 is supplied to the upper end of the tank 10 through the hot air pipe 29, drying of the sludge is started.

투입스크류(10a)를 통하여 투입된 슬러지는 회전디스크(15)에 떨어진 다음 회전디스크(15)를 따라 회전된다. 이때 탱크(10)의 내주면에 고정된 고정막대(18)의 고정날개(19)에 의해 회전중인 슬러지 들이 탱크(10)와 회전디스크(15) 사이의 틈새(17) 쪽으로 이동된 뒤 틈새(17)를 통하여 하부 쪽으로 떨어진다. 하부 쪽으로 떨어진 슬러지는 고정디스크(25)의 상부에 놓이게 되며 이후 회전축(11)과 연결된 회전막대(23)의 회전날개(24)에 의해 회전축(11)의 중앙으로 모이게 된다. 이 과정에서 회전축(11) 근방의 고정디스크(25)에 형성된 배출구멍(27)을 통하여 다른 회전디스크(15) 쪽으로 떨어지는 과정이 다단계로 이루어 진다.The sludge introduced through the feeding screw 10a falls on the rotating disk 15 and then rotates along the rotating disk 15. At this time, the sludge being rotated by the fixed blade 19 of the fixed rod 18 fixed to the inner circumferential surface of the tank 10 is moved toward the gap 17 between the tank 10 and the rotating disk 15 and then the gap 17 Drop down). The sludge dropped toward the lower side is placed on the top of the fixed disk 25 and then collected by the rotary blades 24 of the rotary rod 23 connected to the rotary shaft 11 to the center of the rotary shaft 11. In this process, a process of falling toward the other rotating disk 15 through the discharge hole 27 formed in the fixed disk 25 near the rotating shaft 11 is performed in a multi-step.

위의 과정을 거치면서 슬러지는 잘게 부서지고 또한 열풍에 의해 건조된다.열풍발생기(28)로부터 발생된 열풍은 열풍파이프(28)를 타고 탱크(10)의 상측으로 공급되면 대략 250℃가 된다. 이러한 열풍이 회전디스크(15)와 고정디스크(25)에 형성된 각 구멍(16)(26)과 틈새(17) 및 배출구멍(27)을 타고 탱크(10)의 하부 쪽으로 이동되면서 슬러지를 건조시키게 되며 건조과정에서 발생되는 수증기는 배출구(33)를 따라 사이클론(34)으로 이동된다. 그리고 사이클론(34)과 세정기(35)를 거치면서 슬러지에 포함된 먼지 등의 분진이 제거된 상태로 순수한 수증기만 배출된다.Through the above process, the sludge is crushed and dried by hot air. The hot air generated from the hot air generator 28 becomes approximately 250 ° C. when supplied to the upper side of the tank 10 by the hot air pipe 28. The hot air is moved to the lower portion of the tank 10 through each of the holes 16 and 26 and the gaps 17 and the discharge holes 27 formed in the rotating disk 15 and the fixed disk 25 to dry the sludge. And the water vapor generated in the drying process is moved to the cyclone 34 along the outlet 33. Then, only the pure water vapor is discharged while the dust such as dust included in the sludge is removed while passing through the cyclone 34 and the scrubber 35.

또한 탱크(10)의 하단에는 보조열풍파이프(30)가 연결되어 탱크의 내부로 90℃ 정도의 열풍을 불어 넣기 때문에 슬러지가 수분에 의해 건조성이 저하되지 않는다. 그리고 건조과정에서 결로 현상으로 발생되는 수분을 집수하는 집수조(31)가 마련되어 있음으로 건조가 끝난 슬러지에 수분이 포함되지 않는다. 그리고 최종적으로 건조된 슬러지 들은 배출스크류(1Ob)를 타고 운반통(1Oc)으로 배출된다. 또한 본 발명의 건조장치는 건조하는 과정에서 회전디스크(15)의 일측에 슬러지를 잘게 부수는 파쇄기(20)가 구비됨으로 슬러지가 덩어리지지 않고 쉽게 건조된다.In addition, since the auxiliary hot air pipe 30 is connected to the lower end of the tank 10 and blows hot air at about 90 ° C. into the inside of the tank, the sludge does not degrade the dryness due to moisture. And since the water collecting tank 31 for collecting moisture generated by the condensation phenomenon in the drying process is not included in the dried sludge. Finally, the dried sludge is discharged to the transport container (10c) by the discharge screw (10b). In addition, the drying apparatus of the present invention is provided with a crusher 20 for crushing sludge finely on one side of the rotating disk 15 in the drying process, the sludge does not lump easily dry.

상기한 바와 같이 본 발명에 따르면 탱크의 내부에 다단으로 회전디스크와 고정디스크가 구비되고 또한 고정날개와 회전날개가 각각 구비된 상태에서 이들의조합에 의해 슬러지가 탱크의 상측으로부터 하측으로 이동된다. 그리고 슬러지가 이동되는 동안 열풍을 지속적으로 불어넣기 때문에 슬러지가 신속하게 건조된다. 또한 열풍에 의한 건조방식을 사용하기 때문에 슬러지가 타지 않아 유독성 가스가 발생되지 않으며 또한 건조과정에서 발생되는 수증기는 사이클론과 세정기를 거치면서 분진이 제거됨으로 대기오염이 감소되는 등의 효과가 있다.As described above, according to the present invention, the sludge is moved from the upper side to the lower side of the tank by a combination thereof in the state in which the rotating disk and the fixed disk are provided in multiple stages and the fixed blade and the rotating blade are provided, respectively. The sludge dries quickly because hot air is continuously blown while the sludge is being moved. In addition, since the sludge is not burned due to the drying method by hot air, no toxic gas is generated, and the steam generated during the drying process has the effect of reducing air pollution by removing dust through cyclones and scrubbers.
