Description

전기 투입식 필터프레스 탈수장치{Electro-dewatering system of filter press}Electro-dewatering system of filter press

본 발명은 전기 투입식 필터프레스 탈수장치(Electro-dewatering system of filter press)에 관한 것으로서, 보다 구체적으로는 도시 하수처리장과 공단 및 농공단지 폐수처리장 등에서 발생하는 슬러지를 처리하는 기존의 Filter Press 장치에 전기식 삼투압 원리를 이용한 슬러지 전기 침투 장치를 결합 함으로써, 가압탈수와 전기탈수가 동시에 발생되도록 하여 슬러지에 포함되어 있는 수분을 효과적으로 제거하고자 한 것이다.The present invention relates to an electro-dewatering system of filter press, and more particularly, to an existing filter press apparatus for treating sludge generated in urban sewage treatment plants, industrial complexes, and agricultural industrial wastewater treatment plants. By combining the sludge electro-osmotic apparatus using the electric osmotic principle, it is intended to effectively remove the water contained in the sludge so that pressurized dehydration and electrical dehydration occurs at the same time.

산업의 고도화와 인구 도심화에 따라 도시 하수처리장과 공단 및 농공단지 폐수처리장에서 처리하고 있으며, 이들 처리장 등에서는 오폐수 처리과정에서 다량의 슬러지가 발생한다. 현재까지는 발생되는 대부분의 슬러지를 해양투기, 매립 그리고 소각 등의 방법으로 처리하고 있으나, 해양투기 및 매립과 같은 슬러지 처분 방법은 지가의 상승, 침출수 발생, 환경오염 유발, 지역주민과의 갈등뿐만 아니라 런던 협약의 "슬러지 해양 투기 및 매립금지" 규약에도 위배되는 문제점을 안고 있다.In accordance with the advancement of the industry and the urbanization of the population, the city sewage treatment plants, industrial complexes and agricultural industrial wastewater treatment plants are treated, and large amounts of sludge are generated in the wastewater treatment processes. Until now, most of the sludge generated is treated by ocean dumping, landfilling and incineration.However, sludge disposal methods such as dumping and landfilling are not only rising land prices, leachate generation, environmental pollution, and conflict with local residents. There is also a violation of the London Convention on "Sludge Offshore Dumping and Reclamation".

그래서 최근 들어 퇴비, 아스팔트 충진재, 경량골재, 시멘트 원료 등과 같은 자원화로 이용하는 방법을 통해 슬러지를 재활용하여 최종 발생 슬러지량을 최소화하는 연구들이 활발히 진행되고 있다. 하지만 슬러지 자원화 및 최적의 매립효과를 얻기 위한 필수조건인 슬러지의 함수율 저하 기술의 둔화로 슬러지의 효율적인 처리가 어려운 실정이다.Therefore, recently, studies are being actively conducted to minimize the amount of sludge produced by recycling sludge through the use of resources such as compost, asphalt filler, lightweight aggregate, and cement raw materials. However, it is difficult to efficiently treat sludge due to the sluggishness of sludge water content reduction technology, which is an essential condition for sludge resourceization and optimum landfill effect.

현재 하수종말처리장 및 상수처리장에서 사용하고 있는 슬러지의 감량기술 88%가 Belt Press, Filter Press 그리고 Screw Press와 같은 기계식 탈수 시스템을 채용하고 있으며, 탈수 슬러지의 함수율은 약 80wt% 가량으로 저조한 상태이다. 슬러지를 효율적으로 처리하기 위해서는 함수율이 약 60 wt%정도의 탈수 슬러지를 생산하여야 하는데 기존의 기계식 탈수 처리 기술로는 이와 같은 슬러지 생산이 어려운 것으로 분석되고 있다.Currently, 88% of the sludge reduction technologies used in sewage treatment plants and water treatment plants employ mechanical dehydration systems such as belt presses, filter presses, and screw presses, and the water content of dewatered sludge is low at about 80wt%. In order to efficiently treat sludge, it is necessary to produce dewatered sludge having a water content of about 60 wt%, and it is analyzed that such sludge production is difficult with conventional mechanical dewatering treatment technology.

즉, 기존의 슬러지 탈수장치는 기계적인 탈수 방법(가압, 진공 등과 같은 방법으로 탈수)에 의존하였는데, 이 방법의 의한 탈수는 슬러지에 함유되어 있는 액체중 물리적으로 결합한 액체만 제거할 뿐 화학적으로 결합한 액체는 제거하지 못한다.In other words, the conventional sludge dehydrator relies on mechanical dehydration (dehydration by pressurization, vacuum, etc.), and dehydration by this method removes only the physically bound liquid from the liquid contained in the sludge, The liquid cannot be removed.

따라서 기계적인 탈수 방법은 함수율 저감에 있어 한계가 있다. 현재 상용화되어 있는 기계적 탈수 장치의 경우 최종 슬러지의 함수율은 약 75 wt%에 달하여 수송, 매립, 재활용의 어려울 뿐만 아니라, 탈수 소요시간이 증대되는 등의 여러 문제점이 있었다.Therefore, the mechanical dehydration method has a limitation in reducing the moisture content. In the currently commercialized mechanical dehydration apparatus, the final sludge water content is about 75 wt%, which is difficult to transport, landfill, and recycle, as well as increase in dehydration time.

이에 본 발명자는 상기한 바와 같은 기계적 탈수장치의 문제점을 개선하고자 연구 개발하는데 기술적 과제를 두고 본 발명을 완성한 것이다.The present inventors have completed the present invention with a technical problem in the research and development to improve the problems of the mechanical dehydration device as described above.

본 발명은 기술적 과제를 완성하기 위하여 기존의 Filter Press 장치에 전기식 삼투압 원리를 이용한 슬러지 전기 침투 장치를 결합한 것으로 가압탈수와 전기탈수가 동시에 발생함에 따라 저함수율 케이크를 생산할 수 있도록 한 것으로, 슬러지의 함수율을 최소화하기 위하여 기존의 탈수에 사용되어 오던 기계적인 방법에서 탈피하여 슬러지 양극단에 (+)극판과 (-)극판을 설치하여 전기장을 형성시킴으로서 슬러지에 함유되어 있는 물을 효과적으로 제거하고 하는 것이다.The present invention is to combine the sludge electro-osmotic device using the electrical osmotic principle to the existing filter press device to complete the technical problem to produce a low water content cake as the pressurized dehydration and electrical dehydration at the same time, the water content of the sludge In order to minimize the problem, the mechanical method that has been used in conventional dehydration is removed from the sludge anode and the positive electrode plate and the negative electrode plate (+) to form an electric field to effectively remove the water contained in the sludge.

즉, 양 극판 사이에 형성된 강한 전기장의 영향을 받아 (-)전하를 띠는 슬러지의 고체입자들이 (+)방향으로 이동하고 물은 (-)극판쪽으로 이동하게 되어 탈수가 이루어지는 것이다.That is, under the influence of the strong electric field formed between the anode plates, the solid particles of the sludge carrying negative (-) charges move in the (+) direction, and the water moves toward the (-) pole plates to dehydrate.

본 발명은 고정판(2)과 실린더 등의 가압수단(3)에 의해 슬라이드 이동하는 가압판(4) 상간에 다수개의 필터판(5)을 위치시켜 지지대(6)에 횡방향으로 설치된 안내대(6a)를 따라서 가압판(4)의 작동에 따라서 가압될 수 있도록 하고, 각 필터판(5)에는 슬러지 공급공(5a)을 형성하여 상호 연결시킨다.According to the present invention, a plurality of filter plates 5 are positioned between the fixing plate 2 and the pressing plate 4 which is slid by the pressing means 3 such as a cylinder. In order to be pressurized in accordance with the operation of the pressure plate 4 along the), each filter plate 5 is formed by the sludge supply hole (5a) to be interconnected.

그리고 각 필터판(5) 상간에는 공급되는 슬러지(10)가 내입되는 천으로 된 필터(7)를 위치시켜 내입되는 슬러지(10)에 포함되어 있는 수분을 제거할 수 있도록 하는 것으로서, 이는 기계적인 탈수장치의 필터프레스 탈수장치와 동일한 구성이다.And between each filter plate (5) is to place a filter (7) made of cloth in which the sludge 10 to be supplied is inserted to remove the water contained in the sludge (10), which is mechanical It is the same configuration as the filter press dewatering device of the dewatering device.

본 발명에서는 상기한 바와 같은 필터프레스 탈수장치에 전기장치를 부가하여 슬러지(10)에 화학적으로 결합되어 있는 수분을 분리하여 수분제거의 효율을 향상시키고자 한 것이다.In the present invention, by adding an electric device to the filter press dewatering device as described above to separate the water chemically bonded to the sludge 10 to improve the efficiency of water removal.

The device facing each other is pressurized by the pressurizing means (3) and then applied power to form an electric field in the sludge 10 so as to minimize the moisture contained in the sludge 10.

도 3은 본 발명의 다른 실시예를 보인 요부 발췌 단면도를 도시한 것으로서, 이는 상기한 바와 같은 본 발명의 구성에서 각 필터판(5) 표면에 고압의 압축공기에 의해 팽창하는 팽창플레이트(Membrane)(11)를 위치시켜 가압력을 더욱 향상시키도록 한 것이다.Figure 3 is a cross-sectional view showing the main portion of the excerpt showing another embodiment of the present invention, which is an expansion plate (Membrane) inflated by the high-pressure compressed air on the surface of each filter plate 5 in the configuration of the present invention as described above (11) is placed to further improve the pressing force.

도 4a, 4b, 4c는 본 발명에 적용될 수 있는 극판(8)(9)을 도시한 정면도로서, 이는 Stainless Steel, Chrome(Cr), Carbon-graphite, Platinum(Pt), Lead(Pb), Copper(Cu), Titanium(Ti)과 같은 비철금속제로 제작될 수 있으며, 도면에서와 같이 홀형, 기공형, 격자형 등으로 다양하게 제조될 수 있으며, 극판(8)(9)에 형성되는 구멍(12)은 슬러지(10)에 포함되어 있는 수분의 배출이 양호하게 이루어 질 수 있도록 하는 기능을 한다.4A, 4B, and 4C are front views illustrating pole plates 8 and 9 that may be applied to the present invention, which are stainless steel, chrome (Cr), carbon-graphite, platinum (Pt), lead (Pb), and copper. (Cu), Titanium (Ti) can be made of non-ferrous metals, and as shown in the drawings can be manufactured in a variety of holes, pores, lattice, etc., holes 12 formed in the pole plates (8) (9) ) Serves to ensure good discharge of the water contained in the sludge 10.

도면중 미설명 부호 15는 극판에 전원을 공급하는 배터리를 도시한 것이고, 16은 물받이를 도시한 것이다. 그리고 부호 17은 압축공기를 공급하기 위한 공기압축기를 표시한 것이고 18은 배수관을 도시한 것이다.In the figure, reference numeral 15 shows a battery for supplying power to the pole plate, and 16 shows a drip tray. And reference numeral 17 denotes an air compressor for supplying compressed air and 18 denotes a drain pipe.

이상과 같이 구성될 수 있는 본 발명은 오폐수를 처리하는 정수장치 등에서 발생되는 슬리지(10)에서 수분을 분리하는 장치로 사용될 수 있는 것으로써,The present invention that can be configured as described above can be used as a device for separating the water from the sludge 10 generated in the water purification device for treating waste water,

즉, 본 발명은 도 1에 도시된 바와 같이 슬러리 탱크(slurry tank)(13)와 관체 연결된 펌프(14)를 가동하게 되면 각 필터판(5)에 형성되어 있는 슬러지 공급공 (5a)을 따라서 필터판(5) 상간에 위치하는 필터(7)내에 충진한다. 슬러지(10)를 충진한 다음 가압수단(3)을 작동시키게 되면 가압판(4)에 의해 각 필터판(5)이 이동하여 슬러지(10)가 충진된 필터(7)를 가압하여 슬러지(10)에 포함되어 있는 수분이 배출된다.That is, according to the present invention, when the pump 14 connected to the slurry tank 13 and the tubular body 14 as shown in FIG. 1 is operated along the sludge supply hole 5a formed in each filter plate 5 It fills in the filter 7 located between the filter plate 5 phases. When the sludge 10 is filled and then the pressurizing means 3 is operated, each filter plate 5 is moved by the pressure plate 4 to pressurize the filter 7 filled with the sludge 10 and the sludge 10. Moisture contained in is discharged.

이렇게 슬러지(10)를 압축시켜 1차적으로 탈수시킨 후 양 극판(8)(9)에 전압을 인가하여 슬러지(10)층 내에 전기장을 형성 시켜 2차적으로 탈수가 이루어지는 과정을 겪는다.In this way, the sludge 10 is compressed and dehydrated first, and then a voltage is applied to the anode plates 8 and 9 to form an electric field in the sludge 10 layer to undergo dehydration.

즉, (+)전극과 (-)전극 사이에서 발생한 전기장을 형성시킴으로서 슬러지 (10) 층에 전기영동성(Elecro-Phoresis)과 전기삼투성(Electro-Osmosis)의 작용에 의해 발생되는 전기적 힘을 이용하여 탈수를 유도하게 되는데 이때 양 극판(8)(9)사이에 형성된 강한 전기장의 영향을 받아 (-)전하를 띠는 슬러지(10)의 고체입자들이 (+)극판(8) 방향으로 이동하고 물은 (-)극판(9) 쪽으로 이동하게 되어 탈수가 이루어지는 것이다.In other words, by forming an electric field generated between the (+) electrode and the (-) electrode, the electric force generated by the action of electrophoresis and electro-osmosis on the sludge 10 layer is used. In this case, the solid particles of the sludge 10 having a negative charge are moved in the direction of the positive electrode plate 8 under the influence of the strong electric field formed between the positive electrode plates 8 and 9. The water moves toward the negative electrode plate 9, whereby dehydration occurs.

따라서 기존의 가압탈수에 의한 탈수 효과 보다 탈수율이 월등히 뛰어나게 되며, 도 5에서 보는 바와 같이 탈수의 특성은 세 가지로 분류할 수 있다.Therefore, the dehydration rate is much better than the dehydration effect of the conventional pressurized dehydration, and as shown in FIG. 5, the dehydration characteristics may be classified into three types.

우선 슬러지(10)에 압력만 가할 경우 물리적으로 결합되어 있는 액체만이 제거되고 슬러지(10) 입자가 하부로 이동함에 따라 필터(7)를 막는 현상이 발생하며 탈수 효율은 떨어지게 되는 것이다.First, when only the pressure is applied to the sludge 10, only the liquid that is physically bound is removed, and as the sludge 10 particles move downward, the phenomenon of blocking the filter 7 occurs and the dehydration efficiency is reduced.

하지만 슬러지(10) 층에 전기장을 형성시키게 되면 물리적으로 결합되어 있는 액체뿐만 아니라 화학적으로 결합되어 있는 액체까지 제거할 수 있어 탈수 효율을 향상시킬 수 있을 뿐만 아니라 필터(7)의 막힘 현상을 줄일 수 있으며 탈수 시간 감소의 장점이 있다.However, when the electric field is formed in the sludge 10 layer, not only the liquid that is physically bound but also the chemically bound liquid can be removed, thereby improving the dehydration efficiency and reducing the clogging of the filter 7. And it has the advantage of reducing dehydration time.

한편 본 발명을 도 3에서와 같이 구성할 경우 슬러지(10)를 1차 압축시킬 때 팽창플레이트(11)를 팽창시킴으로서 수분의 탈수를 더욱 효과적으로 행할 수 있다.On the other hand, when the present invention is configured as shown in FIG. 3, by expanding the expansion plate 11 when the sludge 10 is first compressed, dehydration of water can be performed more effectively.

그리고 전극(8)(9)은 슬러지(10) 층내에 균일한 전기장을 형성시켜야 하고 경제성 있어야 하며, 무엇보다 전기에 의한 부식성이 적어야 한다. 본 발명에서는 이와 같은 구비조건을 고려하여 Stainless Steel, Chrome(Cr), Carbon-graphite, Platinum(Pt), Lead(Pb), Copper(Cu), Titanium(Ti)와 같은 비철금속류를 사용하였으며, 전극(8)(9)의 형상 또한 기공형, 홀형, 그리고 격자형등으로 형성하여 슬러지(10)에 포함되어 있는 수분의 배출이 더욱 효과적으로 이루어 질 수 있도록 하였다.In addition, the electrodes 8 and 9 must form a uniform electric field in the sludge 10 layer, be economical, and above all, be less corrosive by electricity. In the present invention, non-ferrous metals such as Stainless Steel, Chrome (Cr), Carbon-graphite, Platinum (Pt), Lead (Pb), Copper (Cu), and Titanium (Ti) were used in consideration of such conditions. The shape of (8) and (9) is also formed in a pore shape, a hole shape, and a lattice shape so that the discharge of water contained in the sludge 10 can be more effectively performed.

<실시예><Example>

본 발명의 탈수장치와 기계식 가압탈수장치를 적용하여 하수 슬러지(10)를 탈수하였다.The sewage sludge 10 was dewatered by applying the dewatering device and the mechanical pressure dewatering device of the present invention.

그 결과 도 6에 나타난 바와 같이 기계식 가압탈수장치의 경우 최종 슬러지의 함수율이 약 80 wt%인데 반해, 본 발명의 경우 함수율이 약 50 wt%로 저감됨을 확인할 수 있다.As a result, as shown in Figure 6, the mechanical pressure of the dewatering device is about 80 wt% of the final sludge, while in the present invention it can be seen that the water content is reduced to about 50 wt%.

따라서 필터프레스 전기 탈수 장치는 기존의 슬러지 탈수 기술을 향상시킬 수 있는 매우 유용한 기술이다.Therefore, the filter press electric dewatering device is a very useful technology to improve the existing sludge dewatering technology.

이상에서 살펴본 바와 같이 본 발명은 기존의 Filter Press 장치에 전기식 삼투압 원리를 이용한 슬러지 전기 침투 장치를 결합하여 가압탈수와 전기탈수가 동시에 발생함에 따라 저함수율 케이크를 생산할 수 있도록 한 것으로, 슬러지의 함수율을 최소화하기 위하여 기존의 탈수에 사용되어 오던 기계적인 방법에서 탈피하여 슬러지 양극단에 (+)극판(8)과 (-)극판(9)을 설치하여 전기장을 형성시킴으로서 슬러지(10)에 함유되어 있는 물을 효과적으로 제거하고 하는 간단한 구성으로써, 종래의 기계식 탈수장치에 비하여 탈수시간 감소에 따른 슬러지 처리 에너지 감소, 최종 슬러지 케이크의 함수율이 50 wt% 이하로 매우 낮기 때문에 슬러지(10)의 효율적 처리를 할 수 있고 이를 재활용 시 별도로 건조하지 않아도 되는 등 기대 이상의 효과를 득할 수 있는 매우 우수한 고안이다.As described above, the present invention is to combine the sludge electrofiltration system using the electric osmotic principle to the existing filter press device to produce a low water content cake as the pressurized dehydration and electrical dehydration occurs at the same time, the water content of the sludge Water is contained in the sludge 10 by forming an electric field by installing a positive electrode plate 8 and a negative electrode plate 9 at the sludge anode end to remove the mechanical method that has been used in conventional dewatering for the purpose of minimization. As a simple configuration that effectively removes the sludge, the sludge treatment energy decreases due to the dehydration time reduction and the final water content of the sludge cake is very low (50 wt% or less), compared to the conventional mechanical dehydrator, so that the sludge 10 can be efficiently treated. And it does not need to be dried separately for recycling, An excellent devised.
