본 발명은 하수고도처리장의 슬러지 건조장치에 관한 것으로서, 보다 상세하게는 슬러리 덩어리가 인입되더라도 적당하게 파쇄하여 작은 입자로 만들면서, 폐수는 별도로 배출시키고, 동시에 슬러지는 건조시킴으로써 슬러지의 수분제거와 파쇄가 거의 동시에 이루어져 시간당 처리량이 크게 향상되고 장치의 운용효율이 보다 크게 향상되는 하수고도처리장의 슬러지 건조장치에 관한 것이다.The present invention relates to a sludge drying apparatus of an advanced sewage treatment plant, and more particularly, even if a slurry lump is introduced, it is properly crushed to make small particles, and the waste water is discharged separately, and at the same time, the sludge is dried to remove water and crush the sludge. The sludge drying apparatus of the sewage treatment plant is substantially improved at the same time so that the throughput per hour is greatly improved and the operation efficiency of the apparatus is further improved.

일반적으로, 슬러지(sludge)란, 진흙상태의 산업폐기물 또는 폐수처리 침전물 등에 대한 일반적인 호칭을 일컫는 것으로, 오니(汚泥)라고도 한다. 금속표면을 산(酸) 처리하는 공정에서나, 물과 접하는 보일러·선박·탱크류 등의 금속표면이 박리·퇴적하여 진흙상태로 된 것을 말하는데, 이때 슬러지의 주성분은 금속 또는 그 화합물이다.In general, sludge refers to a general name for industrial wastes or wastewater treatment sediments in the form of mud, and is also referred to as sludge. In the process of acid-treating the metal surface or the metal surface such as boilers, ships, tanks, etc., which are in contact with water, the metal surface is peeled and deposited to form a mud. The main component of the sludge is metal or a compound thereof.

슬러지 처리과정은 환경 규제가 강화되면서 점차 규제가 심해지고 있으며, 현재 사용중인 매립법에 의한 슬러지 처리는 한계에 달하고 있다. 이는 매립된 슬러지에서 발생하는 침출수에 의한 지하수 등의 환경오염이 심각함이 이미 검증되었고, 매립 공간의 확보 측면에서도 한계에 도달하였기 때문이다.The sludge treatment process is becoming more severe as environmental regulations are strengthened, and sludge treatment by the landfill law currently in use is reaching its limit. This is because environmental pollution such as groundwater caused by leachate from landfilled sludge has been seriously verified and the limit has been reached in terms of securing landfill space.

이러한 슬러지의 처리과정을 최적화하기 위하여 다양한 방법이 시도되고 있는데, 슬러지의 수분을 제거하기 위하여 가열건조방법, 기계적 압착방법, 진공건조 방법 등이 사용되고 있다.Various methods have been tried to optimize the treatment of such sludge, and a heat drying method, a mechanical compression method, and a vacuum drying method are used to remove water from the sludge.

그러나, 상기와 같은 종래의 방법은, 수분을 건조하는 시간 및 건조에 따르는 효율에 문제가 발생한다. 특히, 건조 과정에서 표면이 먼저 건조가 되어 수분의 증발을 막게 되므로, 내부의 수분이 증발하는 것을 방해하게 되고 결과적으로 건조효율이 떨어지는 직접적인 원인이 되는 문제점이 있다. However, the conventional method as described above has problems in terms of drying time and efficiency in drying. In particular, since the surface is first dried in the drying process to prevent evaporation of moisture, there is a problem that the internal moisture is prevented from evaporating, and as a result, the drying efficiency is directly reduced.

따라서, 이러한 건조 방법은 결국 슬러지 내부의 수분을 완전하게 제거하는 데에 많은 시간을 요하게 되므로, 시간당 처리량이 저하하게 되고 장치의 운용 효율이 감소하는 주요한 원인이 되는 문제점이 있다.Therefore, this drying method requires a lot of time to completely remove the water inside the sludge, there is a problem that the throughput per hour is lowered and the main cause of the operation efficiency of the device is reduced.

종래의 세라믹 발열부를 이용한 슬러지 건조 장치는 슬러지 인입부, 세라믹 발열부, 이송부 및 건조물 인출부로 구성되는바, 슬러지 인입부를 통하여 인입되는 슬러지는, 미리 설정된 온도 및 속도로 건조장치를 통과하게 되며 건조 장치를 통과한 후에는 상기 건조물 인출부에 건조물(dry cake) 상태로 수집되어 매립이 가능한 상태가 된다. The sludge drying apparatus using a conventional ceramic heating unit is composed of a sludge inlet, a ceramic heating unit, a conveying unit and a drying unit extracting bar. The sludge introduced through the sludge inlet unit passes through the drying apparatus at a predetermined temperature and speed. After passing through, the dry matter extraction portion is collected in a dry cake state and becomes a state in which the landfill is possible.

이때, 그물망(mesh) 형태의 이송 컨베이어 벨트인 상기 이송부 아래로 슬러지에서 발생하는 폐수가 떨어지게 되며, 이는 장치의 아래로 고여 회수에 문제가 발생한다. 실제로 이러한 폐수는 장치 아래에 있는 폐수 집수 장치(도시되지 않음)에서 모이게 되지만, 건조 장치, 특히 이송용 컨베이어 시스템에는 폐수에 의한 악영향이 발생하게 되는 문제점이 있다.At this time, the wastewater generated in the sludge falls below the conveying unit, which is a mesh conveying belt, which causes a problem in collecting the waste down the apparatus. In practice, such wastewater is collected in a wastewater collection device (not shown) beneath the device, but there is a problem that adverse effects due to the wastewater occur in the drying device, in particular the conveyor system for transport.

이런 종래의 문제점을 해결하기 위해서, 슬러지가 인입되는 슬러지 인입부, 인입된 슬러지를 건조물 인출부로 이송하기 위한 이송부(그물망 컨베이어 벨트를 포함함), 및 상기 이송부에서 건조된 건조물을 수집하기 위한 상기 건조물 인출부 를 포함하여 구성되는, 하수의 고도처리장의 슬러지 건조 장치에 있어서, 상기 이송부의 하단에 배치되며, 인가되는 전원에 의해 가열되어, 상기 이송부에 의해 이송되는 슬러지를 가열하기 위한 상기 발열용 금속판; 상기 이송부에서 배출되는 폐수를 수집하기 위한 폐수처리부; 상기 이송부의 상단에 배치되며, 이송되는 슬러지의 수분을 측정하기 위한 수분계; 및 상기 수분계로부터 수신한 슬러지의 수분양에 따라, 상기 이송부의 이송속도를 제어하기 위한 제어부를 포함하는 하수의 고도처리장의 슬러지 건조장치가 2005년 4월 20일자 실용신안등록 제20-0382513호로 등록공고된바 있었다.In order to solve this conventional problem, a sludge inlet into which sludge is introduced, a conveying unit (including a net mesh conveyor belt) for conveying the introduced sludge to a dry material extracting unit, and the dried material for collecting the dried matter dried at the conveying unit In the sludge drying apparatus of the advanced sewage treatment plant comprising a withdrawal portion, the heat generating metal plate for heating the sludge disposed at the lower end of the transfer portion, heated by an applied power source, and conveyed by the transfer portion ; A wastewater treatment unit for collecting wastewater discharged from the transfer unit; A moisture meter disposed at an upper end of the transfer unit and configured to measure moisture of the sludge to be transferred; And a sludge drying apparatus of an advanced sewage treatment plant including a control unit for controlling the conveying speed of the conveying unit according to the water content of the sludge received from the water meter as a Utility Model Registration No. 20-0382513 dated April 20, 2005. It was announced.

그러나, 이런 종래의 하수의 고도처리장의 슬러지 건조장치는 슬러지가 일정두께의 덩어리로 인입되면 슬러지 덩어리의 겉부위만 발열용 금속판에 의해서 건조될 뿐 내부는 건조되지 못하게 되어 슬러지 내부의 수분을 완전하게 제거하는 데에 많은 시간이 요구되어 시간당 처리량이 저하되며, 장치의 운용 효율이 저하되는 문제점이 있었다.However, in the sludge drying apparatus of the conventional sewage treatment plant, when the sludge is introduced into a mass of a certain thickness, only the outer portion of the sludge mass is dried by the heat generating metal plate, and the inside is not dried, so that the water inside the sludge is completely dried. It takes a lot of time to remove, the throughput per hour is lowered, there was a problem that the operating efficiency of the device is lowered.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 슬러리 덩어리가 인입되더라도 적당하게 파쇄하여 작은 입자로 만들면서, 폐수는 별도로 배출시키고, 동시에 슬러지는 건조시킴으로써 슬러지의 수분제거와 파쇄가 거의 동시에 이루어져 시간당 처리량이 크게 향상되고 장치의 운용효율이 보다 크게 향상되는 하수고도처리장의 슬러지 건조장치를 제공함에 그 목적이 있다.The present invention is to solve the above problems, even when the slurry lumps are introduced into a small particle, while properly crushed into the waste water, the waste water is discharged separately, at the same time the sludge is dried at the same time the water removal and crushing of the sludge is made almost simultaneously It is an object of the present invention to provide a sludge drying apparatus of an advanced sewage treatment plant in which the throughput is greatly improved and the operation efficiency of the apparatus is further improved.

토출공(15)에서 낙하된 뜨거운 건조된 슬러지(50)는 배풍기(18)에 의해서 식혀지면서 슬러지 이송부(30)에 의해서 인출공(33)을 통해 하부로 낙하된다.The hot dried sludge 50 dropped from the discharge hole 15 cools down by the air blower 18 and falls down through the outlet hole 33 by the sludge transfer part 30.

하부로 낙하된 슬러지(50)는 건조물 인출부(40) 내부로 유입된다.The sludge 50 dropped to the lower side is introduced into the building take-out part 40.

이와 같이, 본 발명은 슬러리 덩어리가 인입되더라도 적당하게 파쇄하여 작은 입자로 만들면서, 폐수는 별도로 배출시키고, 동시에 슬러지는 건조시킴으로써 슬러지의 수분제거와 파쇄가 거의 동시에 이루어져 시간당 처리량이 크게 향상되고 장치의 운용효율이 보다 크게 향상되는 효과가 있다.As described above, the present invention makes it possible to properly disintegrate the slurry mass into small particles, discharge the wastewater separately, and dry the sludge at the same time, thereby substantially eliminating the water and crushing the sludge, thereby greatly improving the throughput per hour. Operational efficiency is greatly improved.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
