일반적으로, 지구의 모든 물 중 우리가 사용할 수 있는 양은 고작 0.0086%에 지나지 않는다. 이는 기후변화로 인한 재해를 염두에 둔다면 과히 넉넉한 편은 못된다. In general, we can only use 0.0086% of the world's water. This is not too generous given the disasters caused by climate change.
물은 인간 생활에 있어 매우 중요하고, 생활용수나 산업용수로서 물은 다양하게 이용된다. 산업 발전으로 물이 중금속, 질산성 질소, 불소 이온 등으로 오염되고 있고, 오염된 물을 음용했을 때 건강에 매우 해롭다. Water is very important for human life, and water is widely used as living water or industrial water. Due to industrial development, water is contaminated with heavy metals, nitrate nitrogen, fluorine ions, etc., and it is very harmful to health when drinking contaminated water.
최근, 오염된 물을 정화하고, 해수를 정화하여 용수로 사용하기 위한 탈염 기술이 다양하게 연구되고 있다.Recently, desalination techniques for purifying contaminated water, purifying seawater and using them as water have been studied in various ways.
이러한 탈염 기술은, 해수나 폐수 등와 같은 오염수에 함유되는 각종 부유물질이나 이온성분을 제거하여 담수화하는 기술로, 화석연료나 전기 등의 열원을 이용하여 수분을 증발하는 증발법과, 분리막을 이용한 이물질을 걸러 제거하는 여과법과, 전극셀의 전기분해작용을 이용하여 이온들을 제거하는 전기투석법이 있다.The desalination technology is a technique for desalination by removing various suspended substances or ionic components contained in contaminated water such as seawater and wastewater, and the evaporation method of evaporating moisture using a heat source such as fossil fuel or electricity, and foreign matter using a separator. Filtration to remove the filtration and electrodialysis to remove ions using the electrolysis of the electrode cells.
증발법은, 화석연료나 전기 등을 열원으로 사용하여 수분을 증발시키는 것으로, 탈염장치의 부피가 커서 비효율적이고, 에너지의 소모량이 증대되어 제조단가가 증대될 뿐만 아니라, 화석연료의 사용으로 인한 대기오염의 원인이 된다.The evaporation method is to evaporate water by using fossil fuel or electricity as a heat source. The volume of the desalination unit is large, inefficient, the consumption of energy is increased, and the manufacturing cost is increased. It may cause contamination.
여과법은 분리막에 고압을 가하여 이물질을 제거해야하므로 에너지의 비용이 증대되고, 전기투석법은 지속적으로 전극셀을 교체해야 하므로 전극셀의 교체에 따른 낭비요인이 발생될 뿐만 아니라 전극셀의 교체에 따른 인적 및 물적 부대비용이 증대되는 단점이 있다.Since the filtration method removes foreign substances by applying high pressure to the membrane, the cost of energy increases, and the electrodialysis method requires the replacement of electrode cells continuously. Therefore, wasteful factors are caused by the replacement of electrode cells. There is a disadvantage that the human and material incidental costs are increased.

도 1을 참고하면, 본 발명의 바람직한 실시예에 따른 축전식 탈염 전극 모듈(100)은 다공성 나노섬유 웹 또는 부직포와 같은 다공성 기재(110)의 미세 기공에 탄소 전극 분말(120)이 주입되어 고정된 전도성 지지체(130); 및 전도성 지지체(130)의 일 표면에 도금된 도금층(150)을 포함하고 있다.Referring to Figure 1, the capacitive desalination electrode module 100 according to a preferred embodiment of the present invention is fixed to the carbon electrode powder 120 is injected into the fine pores of the porous substrate 110, such as porous nanofiber web or nonwoven fabric Conductive support 130; And a plating layer 150 plated on one surface of the conductive support 130.
여기서, 탄소 전극 분말(120)은 바인더 및 용매와 혼합하여 탄소 전극 분말(120)이 분산된 탄소 전극 분말 슬러리를 제조하고, 그 슬러리를 다공성 기재(110)의 미세 기공에 주입시켜 고정시킨다.Here, the carbon electrode powder 120 is mixed with a binder and a solvent to prepare a carbon electrode powder slurry in which the carbon electrode powder 120 is dispersed, and the slurry is injected and fixed into the fine pores of the porous substrate 110.
이때, 탄소 전극 분말(120)은 다공성 기재(110)의 미세 기공에 갖혀 고정되어 있다. 이때, 바인더는 탄소 전극 분말(120)과 다공성 기재(110) 사이에 개재되어 있을 수 있으며, 바인더는 탄소 전극 분말(120)을 다공성 기재(110)에 고정시키는 결합력을 증가시킨다.At this time, the carbon electrode powder 120 is fixed to the fine pores of the porous substrate 110. In this case, the binder may be interposed between the carbon electrode powder 120 and the porous substrate 110, the binder increases the bonding force for fixing the carbon electrode powder 120 to the porous substrate 110.
그리고, 후술된 바와 같이, 전도성 지지체(130)는 전기 방사가 가능한 고분자를 용매에 용해시켜 방사용액을 형성한 후, 방사용액을 콜렉터 또는 트랜스퍼 시트 위에 전기방사하여 방사된 나노섬유가 축적되어 미세 기공을 갖는 다공성 나노섬유 웹, 또는 부직포와 같은 다공성 기재(110)에, 전도성을 확보하도록 미세한 탄소 전극 분말(120)이 주입되어 고정된 구조를 갖는다.As described below, the conductive support 130 forms a spinning solution by dissolving a polymer capable of electrospinning in a solvent, followed by electrospinning the spinning solution on the collector or the transfer sheet to accumulate the nanofibers that are spun onto the micropores. To the porous substrate 110, such as a porous nanofiber web, or a non-woven fabric having a fine carbon electrode powder 120 is injected to secure the conductivity has a fixed structure.
이러한 축전식 탈염 전극 모듈(100)은 전도성 지지체(130)가 전기방사된 나노섬유가 축적되어 형성된 미세 기공을 갖는 다공성 나노섬유 웹, 또는 부직포로 이루어지는 다공성 기재(110)에, 전도성을 확보하도록 미세한 탄소 전극 분말(120)이 주입되어 고정된 구조를 갖기 때문에 가요성을 가지면서도 우수한 전기전도도를 가질 수 있다. 그러므로, 본 발명의 축전식 탈염 전극 모듈(100)은 플렉시블한 집전체로 기능한다.The capacitive desalination electrode module 100 is a conductive support 130, the porous nanofiber web having a micropores formed by the accumulation of the electrospun nanofibers, or a porous substrate 110 made of a nonwoven fabric, the fine to ensure conductivity Since the carbon electrode powder 120 is injected to have a fixed structure, the carbon electrode powder 120 may have flexibility and excellent electrical conductivity. Therefore, the capacitive desalination electrode module 100 of the present invention functions as a flexible current collector.
또한, 본 발명의 축전식 탈염 전극 모듈(100)은 전도성 지지체(130)에 도금층(150)이 형성되어 있어, 초박막이 가능하여 탈염장치를 소형화시킬 수 있고, 우수한 전기전도도를 가질 수 있다.In addition, in the capacitive desalination electrode module 100 of the present invention, since the plating layer 150 is formed on the conductive support 130, the thin film can be made ultra-thin and the size of the desalination apparatus can be reduced.

When the porous nanofiber web is applied to the porous substrate 110 of the conductive support 130, as shown in FIG. 2, the carbon electrode powder 120 injected into the porous nanofiber web is disposed outside the nanofibers 111. Is dispersed. At this time, the porous nanofiber web is made of a stack of nanofibers 111, the fine pores are formed by the stacked nanofibers 111, the injected carbon electrode powder 120 is a porous nanofiber along the micropores It is injected into the web and fixed. Meanwhile, the carbon electrode powder 120 may be fixed to the inlet of the micropores outside the nanofibers 111 by a binder. As a result, most of the carbon electrode powder 120 is fixed to micropores made of the nanofibers 111 and distributed on the porous nanofiber web.

도 3a 내지 도 3c는 본 발명의 일실시예에 따른 축전식 탈염 전극 모듈의 제조 방법을 설명하기 위한 개념적인 단면도이다.3A to 3C are conceptual cross-sectional views for describing a method of manufacturing a capacitive desalination electrode module according to an embodiment of the present invention.
도 3a 내지 도 3c를 참고하면, 본 발명의 일실시예에 따른 축전식 탈염 전극 모듈의 제조 방법은 먼저, 고분자 물질을 에어 전기방사하여 얻어진 나노섬유가 적층되어 있고 미세 기공을 갖는 다공성 나노섬유 웹 또는 미세 기공을 갖는 부직포와 같은 다공성 기재를 준비한다(도 3a). 3A to 3C, a method of manufacturing a capacitive desalination electrode module according to an embodiment of the present invention first includes a porous nanofiber web in which nanofibers obtained by air electrospinning a polymer material are stacked and have micropores. Alternatively, a porous substrate such as a nonwoven fabric having fine pores is prepared (FIG. 3A).
다공성 나노섬유 웹은 단일 종류의 고분자 또는 적어도 2 종류의 고분자를 혼합하여 용매에 용해시킨 혼합 방사용액을 전기방사하거나, 또는 서로 다른 고분자를 각각 용매에 용해시킨 후 각각 서로 다른 방사 노즐을 통하여 교차방사하여 얻어질 수 있다.Porous nanofiber webs are either electrospun a single spinning polymer or a mixed spinning solution in which at least two polymers are mixed and dissolved in a solvent, or cross-spinning through different spinning nozzles after dissolving different polymers in a solvent. Can be obtained.
2 종류의 고분자를 사용하여 혼합 방사용액을 형성하는 경우, 예를 들어, 내열성 고분자로서 PAN과 접착성 고분자(또는 팽윤성 고분자)로서 PVDF를 혼합하는 경우, 8:2 내지 5:5 중량% 범위로 혼합하는 것이 바람직하다.In the case of forming a mixed spinning solution using two kinds of polymers, for example, in the case of mixing PAN as a heat resistant polymer and PVDF as an adhesive polymer (or swellable polymer), it is in the range of 8: 2 to 5: 5% by weight. It is preferable to mix.
내열성 고분자와 접착성 고분자의 혼합비가 중량비로 5:5보다 작은 경우 내열성이 떨어져서 요구되는 고온 특성을 갖지 못하며, 혼합비가 중량비로 8:2보다 큰 경우 강도가 떨어지고 방사 트러블이 발생하게 된다.When the mixing ratio of the heat-resistant polymer and the adhesive polymer is less than 5: 5 by weight, the heat resistance is poor and does not have the required high temperature characteristics. When the mixing ratio is larger than 8: 2 by weight, the strength drops and the radiation trouble occurs.

In the present invention, when preparing a spinning solution, in the case of a mixed polymer of a heat resistant polymer material and a swellable polymer material, a single solvent or a two-component mixed solvent in which a high boiling point solvent and a low boiling point solvent are mixed may be used. In this case, the mixing ratio between the two-component mixed solvent and the entire polymeric material is preferably set to about 8: 2 by weight.
본 발명에서는 단일 용매를 사용할 때는 고분자의 종류에 따라 용매의 휘발이 잘 이루어지지 못하는 경우가 있다는 것을 고려하여 방사공정 이후에 후술하는 바와 같이 프리히터에 의한 선 건조구간(Pre-Air Dry Zone)을 통과하면서 다공성 나노섬유 웹의 표면에 잔존해 있는 용매와 수분의 양을 조절하는 공정을 거칠 수 있다.In the present invention, when using a single solvent, considering that the solvent may not be well volatilized depending on the type of the polymer, after the spinning process as described below after the pre-air dry zone (Pre-Air Dry Zone) As it passes, the process may control the amount of solvent and water remaining on the surface of the porous nanofiber web.
