Description
본 발명은 전기삼투압 필터프레스 탈수장치에 관한 것으로서, 각종 하수·상수 처리시에 발생하는 슬러지에 전기장 인가에 따라 발생되는 전기삼투압에 의해 슬러지에 포함되어 있는 결합수를 보다 효율적으로 제거함과 아울러 쿨롱열에 의해 발생하는 수증기를 탈수 도중에 배출하여 최종적으로 얻어지는 탈수케이크상에서의 함수율을 저감시킬 수 있도록 한 탈수장치를 제공코자 한 것이다.The present invention relates to an electroosmotic filter press dewatering apparatus, and more efficiently removes the bound water contained in the sludge by the co-osmotic pressure generated by the application of an electric field to the sludge generated during various sewage and water treatment. It is an object of the present invention to provide a dehydration apparatus which can discharge water vapor generated by dehydration during dehydration to reduce the moisture content on the dehydrated cake finally obtained.
종래에 널리 사용되고 있는 탈수장치로는 압착력을 이용한 필터프레스, 진공에 의한 진공탈수, 그리고 원심력에 의한 원심탈수 등을 들 수 있다.As a dewatering apparatus widely used in the related art, a filter press using a pressing force, a vacuum dehydration by vacuum, and a centrifugal dewatering by centrifugal force may be mentioned.
상기한 바와 같은 종래의 탈수장치의 경우 슬러지 입자의 표면에 이온결합되어 있는 결합수는 제거하지 못하고 다만 탈수가 용이한 자유수만을 제거할 수 있기 때문에 최종 슬러지의 함수율이 매우 높은 문제점이 있었다.In the case of the conventional dehydration apparatus as described above, the water content of the final sludge has a very high problem because the bound water ion-bonded to the surface of the sludge particles cannot be removed but only the free water that is easily dehydrated.
상기한 바와 같은 문제점을 해결코자 전기 탈수장치가 개방되고 있으며 이의 구성을 살펴보면 필터플레이트 사이에 슬러지가 내입되어 여액을 배출하는 여과포를 위치시키고 여과포 외측으로 (+)극판과 (-)극판을 설치한 것으로 이와 같은 구성의 경우 (-)성질을 갖는 대부분의 입자들이 (+)극판 쪽으로 이동하게 되어 여과포에 입자의 과밀현상이 증대되어 여액배출부를 막아 오히려 탈수를 저감시키는 문제점이 있었다. 그리고 상기한 탈수장치의 경우 지속적으로 전기를 공급받는 (+)극판이 알카리성 이온에 의하여 중성화가 초래되어 전기장 형성이 원활히 이루어지지 못하며, 쿨롱열이 발생하여 여액의 일부가 증기화 되어 있다가 슬러지를 외부로 배출할 때 응축되어 슬러지의 수분을 증가시켜 탈수율을 저하시키는 등의 여러 문제점이 있었던 것이다.In order to solve the problems described above, the electric dehydration apparatus is open. Looking at the configuration thereof, sludge is interposed between the filter plates to place the filter cloth for discharging the filtrate, and the positive and negative plates are installed outside the filter cloth. In this case, most of the particles having the (-) property are moved toward the (+) electrode plate, so that the overcrowding of the particles in the filter cloth is increased, thereby preventing the filtrate discharge part, thereby reducing dehydration. In addition, in the dehydration device, the positive electrode plate which is continuously supplied with electricity is neutralized by alkaline ions, and thus electric field is not formed smoothly, and a part of the filtrate is vaporized after coulomb heat is generated. When discharged to the outside it was condensed to increase the water of the sludge has had a number of problems such as lowering the dehydration rate.
이에 본 발명자는 종래의 전기 탈수장치가 갖는 문제점을 개선하고자 연구 개발한 것으로서, 탈수중 슬러지가 여과포에 과밀되는 것을 방지하고, 전기를 단속적으로 공급하여 (+)극판 주위의 중화현상을 감소시켜 전기장이 원활히 이루어 질 수 있도록 함과 아울러 쿨롱열에 의해 발생하는 수증기를 수시로 흡출토록 하여 최종 배출되는 슬러지의 함수율을 저감시킬 수 있는 전기삼투압 필터프레스 탈수장치를 제공함에 본 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.The present inventors have been researched and developed to improve the problems of the conventional electric dehydration device, to prevent the sludge from being dense on the filter cloth during dewatering, and to supply electricity intermittently to reduce the neutralization around the positive electrode plate to reduce the electric field The present invention provides an electroosmotic filter press dewatering apparatus which can reduce the moisture content of the sludge discharged to make the smoothly made and also to suck out the water vapor generated by the coulomb heat from time to time. It is completed.

그리고 본 고안에서는 (+)극판(15)이 전기부식에 의해 손상되는 것을 최소화 할 수 있도록 스테인레스 스틸(SUS)를 사용하고, 표면에는 내식성 물질 즉, 백금, 티타늄, 니켈, 흑연 등을 코팅 구성한다.In the present invention, the positive electrode plate 15 uses stainless steel (SUS) to minimize damage caused by electrical corrosion, and the surface is coated with a corrosion resistant material, that is, platinum, titanium, nickel, graphite, and the like. .
도면중 미설명 부호 19는 물받이를 도시한 것이고 부호 20은 슬러지(10)를 공급하기 위한 압축공기를 공급하는 공기압축기를 표시한 것이다.In the figure, reference numeral 19 denotes a drip tray and reference numeral 20 denotes an air compressor for supplying compressed air for supplying sludge 10.
이상과 같이 구성될 수 있는 본 발명은 오폐수를 처리하는 폐수처리장치 등에서 발생되는 슬리지(10)에 포함되어 있는 수분을 분리하는 장치로 사용될 수 있는 것으로써, 도 1에 도시된 바와 같이 슬러리 탱크(slurry tank)(7)와 관체(8) 연결된 펌프(9)를 가동하게 되면 각 필터플레이트(5)에 형성되어 있는 슬러지공급공(5a)을 따라서 필터플레이트(5) 상간에 위치하는 여과포(6)내에 약 4~6kgf/㎠의 압력으로 슬러지(10)를 충진하게 되고, 충진된 슬러지(10)는 가압수단의 실린더(3) 작동에 의해 1차적으로 슬러지(10)에 포함되어 있는 수분을 탈수한 다음 (+)극판(15)과 (-)극판(12)에 전원을 인가하여 슬러지(10)층 내에 전기장을 형성 시켜 슬러지(10)에 포함되어 있는 결합수를 2차로 탈수하게 되는 것이다.The present invention can be configured as described above can be used as a device for separating the water contained in the sludge 10 generated in the waste water treatment apparatus for treating waste water, as shown in Figure 1 slurry tank When the pump 9 connected to the slurry tank 7 and the pipe body 8 is operated, the filter cloth positioned between the filter plates 5 along the sludge supply holes 5a formed in each filter plate 5 6) filling the sludge 10 at a pressure of about 4 ~ 6kgf / ㎠, the filled sludge 10 is primarily contained in the sludge 10 by the operation of the cylinder 3 of the pressing means After dehydration, power is applied to the (+) pole plate 15 and the (-) pole plate 12 to form an electric field in the sludge 10 layer to dehydrate the combined water contained in the sludge 10 secondly. will be.
즉, 본 발명은 여과포(6) 내측 중앙에 위치하는 (+)극판(15)이 설치되고, 여과포(6) 외측에 (-)극판(12)이 위치하게 되므로 전원을 인가하여 슬러지(10)층에 전기장을 형성시키게 되면 슬러지(10)층에 전기영동성(Elecro-Phoresis)과 전기삼투성(Electro-Osmosis)의 작용에 의해 발생되는 전기적 힘을 이용하여 탈수를 유도하게 되는데, 이때 (+)극판(15)으로는 (-)전하를 띠는 슬러지(10)의 고체입자들이 이동하고, (-)극판(12) 쪽으로 (+)전하를 띠는 물이 이동하게 되어 탈수가 이루어지는 것으로 본 발명에 의하면 슬러지(10) 입자가 (+)극판(15) 쪽 즉, 중앙으로 몰리게 되므로 여과포(6)의 과밀현상을 없앨 수 있어 탈수의 효율을 극대화시킬 수 있게 되는 것이다.That is, according to the present invention, since the positive electrode plate 15 positioned in the center of the filter cloth 6 is installed, and the negative electrode plate 12 is located outside the filter cloth 6, the sludge 10 is applied by applying power. When the electric field is formed in the layer, dehydration is induced by using the electric force generated by the action of electrophoresis and electro-osmosis in the sludge 10 layer. In the present invention, the solid particles of the sludge 10 having the negative charge move to the pole plate 15, and the water having the positive charge moves toward the negative electrode plate 12 to dehydrate. According to the sludge 10 particles are driven to the (+) electrode plate 15, that is, the center, so that the overcrowding of the filter cloth (6) can be eliminated to maximize the efficiency of dehydration.

그리고 본 발명은 여액배출구(13)측으로 단속밸브(16)에 의해 차단되는 진공펌프(17)와 관체(18) 연결하여 쿨롱열에 의해 밸생하는 수증기를 수시로 배출되도록 하여 탈수후 배출되는 슬러지 케이크가 수증기에 의해 함수율이 증가되지 않도록 함으로서 탈수효율을 더욱 향상되도록 한 것이다.And the present invention is connected to the vacuum pump 17 and the tubular body 18 is blocked by the intermittent valve 16 to the filtrate discharge port 13 side to discharge the steam generated by the coulomb heat from time to time to discharge the sludge cake discharged after dehydration By not increasing the water content is to improve the dehydration efficiency further.
이상에서 살펴본 바와 같이 본 발명은 여과포(6) 내측으로 (+)극판(15)을 설치하고, 외측으로 (-)극판(12)을 설치하여 탈수중 슬러지(10)가 여과포(6)에 과밀되는 것을 방지하고, 전기를 단속적으로 공급하여 (+)극판(15) 주위의 중화현상을 감소시켜 전기장이 원활히 이루어 질 수 있도록 함과 아울러 쿨롱열에 의해 발생하는 수증기를 진공펌프(17)로 수시로 흡출토록 하여 최종 배출되는 슬러지(10)의 함수율을 저감시키도록 한 것으로, 슬러지(10)의 효율적 처리는 물론이고 이를 재활용 시 별도로 건조하지 않아도 되는 등 기대 이상의 효과를 득할 수 있는 매우 우수한 발명이다.As described above, in the present invention, the positive electrode plate 15 is installed inside the filter cloth 6, and the negative electrode plate 12 is installed outside, so that the sludge 10 during dehydration is overcrowded on the filter cloth 6. To prevent electricity from being discharged intermittently and to reduce neutralization around the positive electrode plate 15 so that the electric field can be made smoothly, and the vapor generated by the coulomb heat is often sucked out by the vacuum pump 17. In order to reduce the moisture content of the sludge 10 is finally discharged, it is a very excellent invention that can achieve more than expected, such as not only efficient treatment of the sludge 10, but also need not be dried separately during recycling.
