More specifically, the present invention by applying a voltage of 0.1 to 2.0 volts to the activated carbon electrode to quickly adsorb inorganic ions from the industrial wastewater, seawater, brackish water, etc. to the activated carbon electrode through the ion exchange membrane, and then apply the same voltage in reverse Adsorption is prevented according to the role of the ion exchange membrane and the space-saving electrosorption and desorption water purification device is equipped with a plurality of electroadsorption and desorption reactors in one telephone reactor to remove inorganic ions by quickly desorbing the adsorbed ions. It relates to a water purification method using.

일반적으로 소용량의 물을 정화하는 방법에는 역삼투막법, 전기투석 등이 있으나, 역삼투막은 잦은 교체와 저 무기이온 농도에서만 이용되는 단점을 가지고 있다.In general, a small amount of water purification methods include reverse osmosis and electrodialysis, but reverse osmosis membranes have disadvantages that are frequently used only at low concentrations and low inorganic ion concentrations.

고 무기이온 농도이며 소용량의 물을 정화하기 위하여 역삼투막법 대비 에너지소비량을 줄이고 유지관리비용도 낮추며, 전기투석 대비 고 무기이온농도의 물을 정화할 수 있고 또한 저공간에서 정화하는 것이 과제이다. 이러한 문제해결을 위해전기흡탈착원리를 이용한 공간절약형 정화방법이 시도되고 있다.In order to purify a small amount of water with a high inorganic ion concentration, it is a task to reduce energy consumption and lower maintenance cost compared to reverse osmosis membrane method, to purify water with a high inorganic ion concentration compared to electrodialysis, and to purify in a low space. In order to solve this problem, a space-saving purification method using an electrosorption principle has been attempted.

전기흡탈착원리를 이용한 정화방법도 대용량 처리용 직렬 다단 반응조를 소용량에 그대로 이용할 경우 불필요한 많은 공간을 차지하게 된다.Purification method using the electrosorption and desorption principle also takes up a lot of unnecessary space when a large capacity serial cascade reactor is used in a small capacity.

이에 본 발명은 산업폐수, 해수, 기수 등의 고 무기염을 함유하고 있는 물로부터 저공간에서 저비용으로 무기이온을 제거할 수 있는 공간절약형 전기흡탈착식 물 정화장치와 이 장치를 이용한 물 정화방법을 제공하는데 그 목적이 있는 것이다.Accordingly, the present invention provides a space-saving electrosorption-and-desorption water purification device capable of removing inorganic ions at low cost in a low space from water containing high inorganic salts such as industrial wastewater, seawater and brackish water, and a water purification method using the device.

Can be adjusted according to the water quality.

Water enters through the inlet pipe 14 and water flows out through the outlet pipe 16, and a negative voltage is applied to the purification reactor 10 through the negative voltage applying line 22, and through the positive voltage applying line 20. A positive voltage is applied to the purification reaction tank 10.

도 6은 도 2의 전기흡탈착반응기(12)의 평면도이고, 도 7은 전기흡탈착반응기(12)의 정면도이며, 도 8은 전기흡탈착반응기(12)의 측면도이다. 전기흡탈착반응기(12)는 물흐름을 유지하기 위한 스페이서(24), 음극집전체(26), 음전극(28), 양이온교환막(30), 음이온교환막(32), 양전극(34), 양극집전체(36) 등으로 구성되어 있다. 물의 처리용량에 맞게 여러 단으로 자유로이 구성요소를 증가하여 설치할 수 있다.6 is a plan view of the electrosorption desorption reactor 12 of FIG. 2, FIG. 7 is a front view of the electrosorption desorption reactor 12, and FIG. 8 is a side view of the electrosorption desorption reactor 12. The electrosorption and desorption reactor 12 includes a spacer 24 for maintaining water flow, a negative electrode current collector 26, a negative electrode 28, a cation exchange membrane 30, an anion exchange membrane 32, a positive electrode 34, and a positive electrode collection. The whole 36 is comprised. The components can be freely increased in multiple stages to accommodate the water treatment capacity.

도 9는 정화반응조(10)내의 물의 흐름방향을 나타내고 있으며 유입관(14)을 통하여 물이 전화반응조 내로 유입되고 스페이서(24)을 통해서 정화반응조의 가장자리로 이동한 후 가운데 위치한 스페이서(24)를 통하여 중심 구멍으로 이동한 후 윗 단으로 들어가고 다시 같은 과정을 반복한 후 최종 유출관(16)을 통하여 정화반응조 외부로 유출된다. 물이 단위 셀의 가운데 스페이서 내를 이동하는 중에 물중의 양이온들은 양이온교환막(30)을 통과하여 0.1 내지 2.0볼트의 음전압이 인가된 음전극(28)에 흡착되고 음이온들은 음이온교환막(32)을 통과하여 0.1 내지 2.0볼트의 양전압이 인가된 양전극(34)에 흡착하게 된다. 이온들이 각 전극에 흡착포화되면 이 이온들을 탈착시켜 제거하는 재생공정이 이어지게 되며 이 공정에서는 흡착공정에서와는 반대로 음전극(28)에는 0.1 내지 2.0볼트의 양전압이 인가되고 양전극(34)에는 0.1 내지 2.0볼트의 음전압이 인가됨으로서 각 전극에 흡착된 이온들이 탈착되게 된다.FIG. 9 shows the flow direction of water in the purification reaction tank 10. The water flows into the inversion reactor through the inlet pipe 14 and moves to the edge of the purification reaction tank through the spacer 24. After moving to the center hole through the upper end and repeating the same process again through the final outflow pipe 16 is discharged to the outside of the purification reaction tank. As water moves in the center spacer of the unit cell, cations in the water pass through the cation exchange membrane 30 and are adsorbed to the negative electrode 28 to which a negative voltage of 0.1 to 2.0 volts is applied, and the anions pass through the anion exchange membrane 32. To the positive electrode 34 to which a positive voltage of 0.1 to 2.0 volts is applied. When the ions are adsorbed and saturated on each electrode, a regeneration process of desorbing and removing these ions is continued. In this process, a positive voltage of 0.1 to 2.0 volts is applied to the negative electrode 28 and 0.1 to 2.0 volts to the positive electrode 34 as opposed to the adsorption process. As a negative voltage of is applied, ions adsorbed to each electrode are desorbed.

이 때 음이온은 양이온교환막(30)을, 그리고 양이온은 음이온교환막(32)을 통과할 수 없기 때문에 각 전극으로의 흡착반응은 전혀 발생하지 않는다. 따라서 재생효율이 극대화된다. 따라서 처리할 물의 수질에 따라 정화반응조(10)내의 직렬로 연결되는 전기흡탈착반응기(12)의 수를 적절히 조절하면 된다. 정화반응조 내의 양전극(34)과 음전극(28)은 같은 활성탄소재질로 만들어진 전극으로 이루어져 있고 집전체는 탄소호일로 구성되어 있다. 여러 개의 전기흡탈착반응기(12)가 하나의 정화반응조(10)내에 구성되어 있기 때문에 필요공간이 집약되어 있다.At this time, since the anion cannot pass through the cation exchange membrane 30 and the cation cannot pass through the anion exchange membrane 32, no adsorption reaction to each electrode occurs. Therefore, the regeneration efficiency is maximized. Therefore, the number of the electrosorption and desorption reactors 12 connected in series in the purification reaction tank 10 may be appropriately adjusted according to the water quality of the water to be treated. The positive electrode 34 and the negative electrode 28 in the purification reaction tank are made of electrodes made of the same activated carbon material, and the current collector is made of carbon foil. Since several electrosorption and desorption reactors 12 are constituted in one purification reaction tank 10, the necessary space is concentrated.

본 발명의 전기흡탈착식 물 정화장치는 하나의 정화반응조 내에 여러 개의 전기흡탈착반응기가 직렬로 연결 설치되어 있기 때문에 소용량 처리의 경우 공간절약형이며 또한 수질에 따라 전기흡탈착반응기내에 병렬로 연결되는 단위 셀수를 자유로이 조절할 수 있어 구성이 용이하고, 편리하다.The electrosorption and desorption water purifying apparatus of the present invention is a space-saving type in the case of small capacity treatment and is connected in parallel in the electrosorption and desorption reactor depending on the water quality since several electrosorption and desorption reactors are installed in series in one purification reactor. The number of cells can be freely adjusted for easy configuration and convenience.

또한, 0.1 내지 2.0 볼트의 낮은 전기를 이용함으로서 에너지소비량이 적고 재생시 약품을 사용하지 않아 환경오염이 없으며, 유지관리가 편리하다. 또한 이온교환막을 부가하여 사용함으로서 재생효율이 극대화 된다. 따라서 경제적으로 고농도 무기물을 함유하는 물을 정화하여 소용량으로 각종 용수를 생산하여 각 용도로 활용할 수 있다.In addition, by using low electricity of 0.1 to 2.0 volts, the energy consumption is low, and there is no environmental pollution, and there is no environmental pollution, and maintenance is convenient. In addition, the regeneration efficiency is maximized by adding an ion exchange membrane. Therefore, it is economically possible to purify water containing high concentration minerals and produce various waters with small capacity and use them for each purpose.
