Description

압축판을 이용한 슬러지 탈수 및 고형화 장치{SLUDGE DEWATERING AND SOLIDIFICATION DEVICE USING COMPRESSION PLATE}Sludge dewatering and solidifying device using compressed plate {SLUDGE DEWATERING AND SOLIDIFICATION DEVICE USING COMPRESSION PLATE}

본 발명은 압축판을 이용한 슬러지 탈수 및 고형화 장치에 관한 것으로, 보다 상세하게는, 슬러지의 탈수 및 고형화 공정을 연속적으로 진행할 수 있는 압축판을 이용한 슬러지 탈수 및 고형화 장치에 관한 것이다.The present invention relates to a sludge dewatering and solidifying apparatus using a compressed plate, and more particularly, to a sludge dewatering and solidifying apparatus using a compressed plate capable of continuously carrying out the sludge dewatering and solidifying process.

현재 하수 처리장에서 발생하는 하수 슬러지 또는 폐수 처리장에서 발생하는폐수 슬러지, 양돈 폐수 슬러지, 축분 슬러지, 공정 슬러지 등 기타 유기 물질이 포함된 슬러지의 배출량이 날로 증가하고 있는 실정이다.Currently, the amount of sludge containing sewage sludge generated from sewage treatment plants or wastewater sludge generated from wastewater treatment plants, swine wastewater sludge, condensed sludge, process sludge and other organic substances including sludge is increasing day by day.

이러한 상황에서, 상기 슬러지는 크게 육상 매립, 해양 투기, 소각 또는 연료화의 방식으로 처리되고 있으며, 특히 슬러지를 처리하여 고형연료로 재활용하려는 많은 기술이 발전해 오고 있다.In this situation, the sludge is largely treated by landfill, ocean dumping, incineration or fueling, and many technologies have been developed to treat sludge and recycle it into solid fuel.

즉, 최근에는 하수슬러지 등의 폐기물 자원화에 대한 시도와 연구가 다양한 형태로 진행되고 있고, 그 일환으로 하수슬러지를 토양으로 환원하거나 건축자재로 활용하거나 유효성분을 분해 환원시키거나 또는 고형연료로 재사용하는 등 다양한 방법이 강구되고 있으며, 그 중 폐기물고형연료(RDF: Refuse Derived Fuel)로 재사용하는 방법은 하수슬러지를 펠렛(pellet), 큐브(cube), 연탄(briquette) 상으로 압축 성형하여 석탄이나 가스 및 석유의 대체연료로 사용할 수 있도록 한 것으로 슬러지의 처리효과와 자원의 재활용 효과를 동시에 거둘 수 있는 장점이 있다.In other words, in recent years, attempts and researches on waste resources such as sewage sludge have been conducted in various forms, and as part of this, the sewage sludge is reduced to soil, used as building materials, active ingredients are decomposed, reduced or reused as solid fuel. Various methods have been devised, and among them, the method of reusing waste solid fuel (RDF) as refrigerated waste fuel (RDF) is compression-molded sewage sludge into pellets, cubes, briquettes, and the like. It can be used as an alternative fuel for gas and oil, and has the advantage of simultaneously treating sludge and recycling of resources.

한편, 하수슬러지는 발생원이나 지역적 특성에 따라 구성 성분도 매우 다양하지만 70~85wt%가 수분이고 나머지가 가연분 및 회분이며, 총량 중 가연분이 10~14wt% 정도를 차지한다. 또한, 건조 고형분 자체의 발열량이 3000~5000kcal/kg-waste이고, 완전연소시 CO, 황산화물(SOx), 질소산화물(NOx) 환경기준치를 초과하지 않은 것으로 보고되어 대체연료로서의 가치를 갖는다.On the other hand, sewage sludge is very diverse depending on the source or regional characteristics, but 70 ~ 85wt% is water, the remainder is combustible ash and ash, and the combustible ash occupies about 10 ~ 14wt% of the total amount. In addition, the calorific value of the dry solid itself is 3000 ~ 5000kcal / kg-waste, it is reported that does not exceed the CO, sulfur oxides (SOx), nitrogen oxides (NOx) environmental standard value when completely burned, it has a value as a substitute fuel.

그러나, 하수슬러지는 70~85 wt%가 수분이기 때문에 연료로서 사용하기 위해서는 수분을 제거하기 위한 공정이 필수적으로 포함되고, 상기 수분제거공정은 전체 공정에 투입되는 에너지의 30~40%를 차지하여 하수슬러지 고형연료의 생산성과 생산비용에 결정적인 영향을 미침으로 수분제거공정의 효율화가 하수슬러지 고형연료 생산에 있어 매우 중요한 과제이다.However, since the sewage sludge is 70 to 85 wt% of water, a process for removing water is essential for use as a fuel, and the water removal process occupies 30 to 40% of the energy input to the entire process. As it has a decisive influence on the productivity and production cost of sewage sludge solid fuel, the efficiency of water removal process is a very important task in the production of sewage sludge solid fuel.

즉, 종래의 하수슬러지는 슬러지 탈수 장치에 의해 수분을 제거하는 탈수 공정을 거친 후 슬러지 고형화 장치의 고형화 공정을 통해 고형연료로 제조되어 재활용되는 것이다.That is, the conventional sewage sludge is manufactured and recycled through a solid fuel through a solidification process of the sludge solidification apparatus after the dehydration process of removing water by the sludge dewatering apparatus.

따라서, 종래에는 하수슬러지를 고형연료로 재활용 시 슬러지의 탈수 공정과 고형화 공정이 각각 별도의 장치에서 진행됨에 따라, 하수슬러지를 고형연료로 재활용하기 위한 효율성이 떨어질 수밖에 없고, 공정설비의 구축에 따른 경제적인 부담이 작용하게 되는 문제점이 있었다.Therefore, conventionally, when the sewage sludge is recycled as a solid fuel, the dewatering and solidification processes of the sludge are performed in separate apparatuses, so that the efficiency for recycling the sewage sludge to solid fuel is inevitably reduced, and according to the construction of the process equipment. There was a problem that the economic burden is working.

또한, 약품저장용기(42)는 슬러지가 이송스크류(20)에 의해 배출부(14)로 이송되고 압축판(30)에 의해 압축될 때, 슬러지에 일정량의 약품을 공급할 수 있도록 그 입구에 제어부(46)의 제어에 따라 작동되는 전자밸브(43)가 설치된다. 전자밸브(43)는 약품저장용기(42)의 입구를 개폐하는 역할을 담당한다.In addition, the chemical storage container 42 is a control unit at the inlet so that when the sludge is transported to the discharge portion 14 by the conveying screw 20 and compressed by the compression plate 30, a certain amount of chemicals can be supplied to the sludge. A solenoid valve 43 actuated under the control of 46 is provided. The solenoid valve 43 plays a role of opening and closing the inlet of the chemical storage container 42.

여기서, 약품저장용기(42)에 저장되는 약품은 고화제이며, 이러한 고화제가 압축된 슬러지에 첨가됨으로써, 슬러지는 최종적으로 고형화될 수 있게 되는 것이다.Here, the medicine stored in the chemical storage container 42 is a solidifying agent, and the solidifying agent is added to the compressed sludge so that the sludge can be finally solidified.

감지부(44)는 슬러지가 압축판(30)에 의해 압축되는 경우, 탄성수단(32)의 탄성 변형을 감지하여 일정 신호를 발생시키며, 압축판(30)의 후방에 배치되어 탄성수단(32)과 접촉되도록 하우징(10)에 설치된다. 이때, 감지부(44)는 로드센서로 마련된다.When the sludge is compressed by the compression plate 30, the detection unit 44 detects the elastic deformation of the elastic means 32 to generate a predetermined signal, and is disposed at the rear of the compression plate 30 so that the elastic means 32. It is installed in the housing 10 so as to contact with. At this time, the sensing unit 44 is provided as a load sensor.

이러한 감지부(44)는 탄성수단(32)의 탄성 변형시 발생하는 압력 변화를 감지하여 감지신호를 발생시키고 이를 제어부(46)로 전송하게 된다.The detector 44 detects a pressure change generated when the elastic member 32 elastically deforms, generates a detection signal, and transmits the detected signal to the controller 46.

즉, 감지부(44)는 슬러지가 이송스크류(20)에 의해 이송되면서 압축판(30)의 전방으로 모여 압축되는 경우, 압축판(30)에 작용하는 슬러지의 압력으로 인한 탄성수단(32)의 수축 시 발생하는 압력 변화를 감지하여 제어부(46)로 전송하게 되는 것이다.That is, the sensing unit 44 is the elastic means 32 due to the pressure of the sludge acting on the compression plate 30, when the sludge is collected by the conveying screw 20 to the front of the compression plate 30 is compressed. The change in pressure generated when the contraction of the will be transmitted to the control unit 46.

여기서 감지부(44)는 탄성수단(32)의 탄성 변형이 발생하지 않는 경우, 압력 변화가 없는 것으로 판단하여 감지신호를 발생시키지 않게 된다.In this case, when the elastic deformation of the elastic means 32 does not occur, the sensing unit 44 determines that there is no pressure change and does not generate a detection signal.

제어부(46)는 약품저장용기(42)의 입구에 설치된 전자밸브(43)의 작동을 제어한다.The controller 46 controls the operation of the solenoid valve 43 installed at the inlet of the chemical storage container 42.

이러한 제어부(46)는 감지부(44)로부터 감지신호가 전송되면, 기 설정된 정보에 따라 전자밸브(43)에 제어신호를 발생시키고, 전자밸브(43)는 제어부(46)의 제어신호에 따라 자동 개방되도록 작동된다.When the detection signal is transmitted from the detection unit 44, the control unit 46 generates a control signal to the solenoid valve 43 according to preset information, and the solenoid valve 43 according to the control signal of the control unit 46. It is operated to open automatically.

즉, 제어부(46)는 감지부(44)로부터 감지신호가 전송되는 경우에 제어신호를 발생시켜 전자밸브(43)를 개방하고, 감지부(44)로부터 제어신호가 전송되지 않는 경우에 전자밸브(43)를 폐쇄하게 된다. 이에 따라, 제어부(46)는 슬러지의 압축 시에만 슬러지에 고형화를 위한 약품이 공급되도록 전자밸브(43)를 개방할 수 있게 되는 것이다.That is, the control unit 46 generates a control signal when the detection signal is transmitted from the detection unit 44 to open the solenoid valve 43, and the solenoid valve when the control signal is not transmitted from the detection unit 44. (43) will be closed. Accordingly, the controller 46 may open the solenoid valve 43 so that the chemicals for solidification are supplied to the sludge only when the sludge is compressed.

이하, 도 5를 참조하여, 본 발명에 따른 압축판을 이용한 슬러지 탈수 및 고형화 장치의 작동 상태를 설명한다.Hereinafter, with reference to Figure 5, the operating state of the sludge dewatering and solidifying apparatus using a compression plate according to the present invention.

먼저, 슬러지의 탈수 및 고형화를 위해 외부의 동력전달수단에 의해 이송스크류(20)를 회전시키는 과정이 선행된다.First, the process of rotating the feed screw 20 by an external power transmission means for the dewatering and solidification of the sludge is preceded.

도 5에 도시된 바와 같이, 수분이 포함된 슬러지(S)는 하우징(10)의 투입부(12)로 투입된 후, 이송스크류(20)에 의해 배출부(14)로 서서히 이송되게 된다. 이러한 슬러지(S)는 하우징(10)을 따라 이송되는 과정에서 배수공(16)을 통해 수분이 배출되므로, 슬러지(S)의 탈수가 진행될 수 있게 되는 것이다.As shown in FIG. 5, the sludge S containing water is introduced into the inlet 12 of the housing 10, and then gradually transferred to the discharge unit 14 by the transfer screw 20. Since the sludge S is discharged through the drain hole 16 in the process of being transported along the housing 10, the sludge S may be dehydrated.

상기와 같이, 슬러지(S)는 탈수가 진행된 후, 이송스크류(20)에 의해 하우징의 배출부(14)로 이송되면서 압축판(30)에 의해 압축되게 된다. 즉, 슬러지(S)는 이송스크류(20)에 의해 이송되어 압축판(30)의 전방으로 모이게 되는데, 압축판(30)은 탄성수단(32)을 매개로 하우징(10)에 지지되는 구조에 따라 이송스크류(20)에 의해 강제 이송되는 슬러지(S)를 자연스럽게 압축할 수 있게 되는 것이다.As described above, the sludge S is compressed by the compression plate 30 while being transferred to the discharge portion 14 of the housing by the transfer screw 20 after dehydration proceeds. That is, the sludge (S) is conveyed by the transfer screw 20 is collected in the front of the compression plate 30, the compression plate 30 is in a structure that is supported by the housing 10 via the elastic means 32 As a result, the sludge S forced by the conveying screw 20 can be naturally compressed.

상기와 같이, 슬러지(S)가 압축판(30)에 의해 압축되는 경우, 탄성수단(32)은 압축판(30)에 작용하는 슬러지(S)의 압력으로 인하여 수축되도록 탄성 변형되고, 감지부(44)는 탄성수단(32)의 수축 시 발생하는 압력 변화를 감지하여 이를 제어부(46)로 전송하게 되며, 제어부(46)는 감지부(44)의 감지신호에 따라 약품저장용기(42)의 입구에 설치된 전자밸브(43)를 개방하게 된다.As described above, when the sludge S is compressed by the compression plate 30, the elastic means 32 is elastically deformed to contract due to the pressure of the sludge S acting on the compression plate 30, the sensing unit 44 detects a pressure change generated when the elastic means 32 contracts and transmits the pressure change to the controller 46, and the controller 46 stores the chemical storage container 42 according to a detection signal of the detector 44. The solenoid valve 43 installed at the inlet is opened.

즉, 제어부(46)는 슬러지(S)의 압축 시 감지부(44)의 신호에 따라 약품저장용기(42)에 설치된 전자밸브(43)를 개방하게 되고, 약품저장용기(42)는 전자밸브(43)의 개방에 따라 압축된 슬러지(S)에 약품을 공급하게 된다. 그 결과, 슬러지(S)는 약품의 첨가에 따라 고형화되어 하우징(10)의 배출부(14)를 통해 배출될 수 있게 되는 것이다.That is, the controller 46 opens the solenoid valve 43 installed in the chemical storage container 42 according to the signal of the detection unit 44 when the sludge S is compressed, and the chemical storage container 42 is the solenoid valve. The chemicals are supplied to the compressed sludge S along the opening of the 43. As a result, the sludge S is solidified in accordance with the addition of the chemical to be discharged through the discharge portion 14 of the housing 10.

상기와 같은 일련의 과정을 통해, 슬러지(S)는 하우징(10)의 투입부(12)를 통해 투입된 후, 탈수 및 고형화되어 배출부(14)로 배출되는 것이다.Through the series of processes as described above, the sludge S is introduced through the inlet 12 of the housing 10, and then dewatered and solidified to be discharged to the outlet 14.

이상 설명한 바와 같이, 본 발명에 따른 압착판을 이용한 슬러지 탈수 및 고형화 장치는, 슬러지의 탈수 및 고형화 공정이 각각 다른 장치에서 진행되는 종래 기술과 달리, 하나의 장치에서 슬러지의 탈수 및 고형화 공정이 동시에 진행됨으로써 작업의 효율성을 향상시킬 수 있고, 공정설비의 구축에 따른 경제적인 부담을 줄일 수 있다.As described above, in the sludge dewatering and solidifying apparatus using the press plate according to the present invention, unlike the prior art in which the sludge dewatering and solidifying process is carried out in a different device, the sludge dewatering and solidifying process in one device at the same time By doing so, the efficiency of the work can be improved and the economic burden of the construction of the process equipment can be reduced.

또한, 본 발명에 따른 압착판을 이용한 슬러지 탈수 및 고형화 장치는, 슬러지의 탈수 및 고형화가 동시에 이루어지는 공정의 개선을 통해 슬러지를 재활용하는 고체연료의 대량생산에 기여할 수 있다.In addition, the sludge dewatering and solidifying apparatus using the press plate according to the present invention can contribute to the mass production of solid fuel to recycle the sludge through the improvement of the process in which the sludge is dewatered and solidified at the same time.
