Description

키토산섬유를 이용한 정수필터{Filter for water purifier using chitosan fiber}Filter for water purifier using chitosan fiber

본 발명은 키토산섬유를 이용한 정수기용 필터에 관한 것이다. 더욱 상세하게 키토산섬유를 정수기용 필터로 이용하는 기술에 관한 것이다. The present invention relates to a filter for a water purifier using chitosan fiber. In more detail, it relates to a technology using chitosan fiber as a filter for a water purifier.

중력방식의 정수장치는 가격이 저렴하며, 필터를 쉽게 교체할 수 있고, 전기를 사용하지 않으며, 설치가 필요 없고, 부피가 작다는 장점들을 가지고 있어서 동남아시아 등 저개발 국가의 저소득층 및 전기가 들어오지 않는 지역의 주민들이 많이 선호하고 있는 정수장치이다. Gravity-type water purifiers have the advantages of low price, easy filter replacement, no electricity, no installation required, and small volume. It is a water purifier that is preferred by many residents.

그러나 종래의 중력식 정수장치는 이온교환에 의해 오염물질 들을 정전기적 인력으로 흡착하기 때문에 접촉시간이 중요하다. 따라서 유속이 빨라질수록 오염물질 제거 성능이 낮아지며, 빠른 정수속도와 높은 중금속 제거율을 동시에 만족시키기가 어려운 문제가 있었다. However, the contact time is important because the conventional gravity-type water purifier adsorbs pollutants by electrostatic attraction by ion exchange. Therefore, the faster the flow rate, the lower the pollutant removal performance, and there was a problem in that it was difficult to simultaneously satisfy the fast water purification speed and the high heavy metal removal rate.

즉, 정수속도가 빠른 필터의 경우 중금속 등 이물질 제거가 잘 이루어지지 않는다. 반대로 중금속 제거율을 높이면, 정수속도가 느려지는 문제가 있다. 이에 따라 시장에서는 빠른 정수속도와 높은 중금속 제거율을 동시에 구현할 수 있는 필터에 대한 요구가 있어 왔다. In other words, in the case of a filter with a high water purification speed, it is difficult to remove foreign substances such as heavy metals. Conversely, if the heavy metal removal rate is increased, there is a problem in that the water purification speed is slowed down. Accordingly, there has been a demand in the market for a filter capable of simultaneously implementing a fast water purification speed and a high heavy metal removal rate.

본 발명은 상기한 문제점을 해결하기 위하여, 본 발명의 키토산섬유를 이용한 무전원 중력방식 정수기용 필터는 고농도의 작용기들을 고분자 매트릭스에 포함하여 형성된 이온교환수지층, 활성탄소섬유층 및 상기 이온교환수지층과 상기 활성탄소섬유층 사이에 위치하는 활성탄층을 포함한 정수필터에 있어서,The present invention in order to solve the above problems, the filter for a non-powered gravity type water purifier using the chitosan fiber of the present invention includes an ion exchange resin layer, an activated carbon fiber layer and the ion exchange resin layer formed by including a high concentration of functional groups in a polymer matrix and In the water filter comprising an activated carbon layer positioned between the activated carbon fiber layers,

상기 활성탄소섬유층은 키토산섬유층이고, 표면개질 된 것을 특징으로 한다. The activated carbon fiber layer is a chitosan fiber layer, characterized in that the surface is modified.

상기 키토산섬유층의 키토산섬유는 속이 비어있는 중공섬유이다. 상기 활성탄층의 두께는 1㎜ 내지 50㎜이고, 상기 이온교환수지층의 두께는 5㎜ 내지 70㎜이고, 상기 키토산섬유층의 두께는 1㎜ 내지 10㎜이다.The chitosan fibers of the chitosan fiber layer are hollow fibers.

도 1은 본 발명의 일실시예에 따른 키토산섬유를 이용한 정수필터의 단면도이다. 도 1에 도시된 바와 같이, 본 발명의 정수필터(10)는 이온교환수지층(11), 활성탄층(12), 키토산섬유층(13), 제1부직포층(14)과 제2부직포층(15)으로 구성된다. 1 is a cross-sectional view of a water filter using chitosan fibers according to an embodiment of the present invention. 1, the water filter 10 of the present invention has an ion exchange resin layer 11, an activated carbon layer 12, a chitosan fiber layer 13, a first non-woven fabric layer 14 and a second non-woven fabric layer ( 15) consists of

활성탄, 활성탄소섬유 및 기타 다공성 탄소재료과 같은 활성탄소는 식품, 의약, 및 화학공업 등 다양한 분야에서 흡착재로 많이 사용되고 있다. 활성탄소는 원료물질의 종류에 따라 다양한 종류로 나누어지며 활성화의 종류에 따라 다양한 내부 표면적을 갖는 흡착재로 제조할 수 있다. Activated carbon, such as activated carbon, activated carbon fiber, and other porous carbon materials, is widely used as an adsorbent in various fields such as food, medicine, and chemical industry. Activated carbon is divided into various types according to the type of raw material, and can be manufactured as an adsorbent having various internal surface areas according to the type of activation.

활성탄소섬유(Activated Carbon Fiber: ACF)는 아크릴수지, 석유 또는 석탄에서 얻어지는 피치 등의 유기물을 섬유로 만든 다음 특수한 열처리 공정을 거쳐 만들어지는 탄소섬유를 활성화시켜 제조한다. 활성탄소섬유는 활성탄에 비해 기공이 대부분 미세기공으로 구성된다. Activated Carbon Fiber (ACF) is manufactured by activating carbon fibers made from acrylic resins, organic materials such as pitch obtained from petroleum or coal into fibers and then undergoing a special heat treatment process. Compared to activated carbon, activated carbon fibers are mostly composed of micropores.

활성탄소섬유는 기공 크기가 비교적 균일하여 분자체 효과가 뛰어나고, 섬유 직경(6~10㎛)이 작아서 균일한 흡착 특성을 얻을 수 있다. 또한 내부기공이 모두 외부 표면에 직접 연결되어 있기 때문에 물질전달속도가 매우 빠르고, 인장강도와 탄성률이 우수하며, 열/전기전도도, 밀도 등의 물성 조절이 용이하다. 또한 내열성, 내부식성, 내층격성이 우수하고, 고온에서의 열팽창 수축이 거의 없는 성질 등 활성탄에 비해 매우 우수한 특성이 있다. 본 발명의 일 실시예에 따른 활성탄소섬유는 키토산섬유이다. Activated carbon fiber has a relatively uniform pore size, so the molecular sieve effect is excellent, and the fiber diameter (6-10 μm) is small, so uniform adsorption properties can be obtained. In addition, since the internal pores are all directly connected to the external surface, the mass transfer rate is very fast, the tensile strength and elastic modulus are excellent, and physical properties such as thermal/electric conductivity and density are easy to control. In addition, it has excellent properties compared to activated carbon, such as excellent heat resistance, corrosion resistance, and interlayer toughness, and almost no thermal expansion and contraction at high temperatures. Activated carbon fiber according to an embodiment of the present invention is a chitosan fiber.

키틴, 키토산은 새우, 게 등의 갑각류의 껍질, 갑충의 갑피 등 절족동물의 외골격, 연체동물의 기관, 곰팡이, 효모, 버섯 등 진균류의 세포벽 등에 함유되어 존재한다. 그리고 생체 내에서는 탄수화물과 단백질의 결합된 형태로 존재한다. 키틴이 생물의 외피를 형성하기 때문에 1823년에 프랑스의 과학자 오질지이가 그리스어로 봉투를 의미하는 키틴으로 명명하였다. 키틴은 사람의 소화효소로는 분해되지 않아 어느 정도 식이섬유와 같은 성질을 가지고 있다. Chitin and chitosan are present in the shells of crustaceans such as shrimp and crabs, the exoskeletons of arthropods such as the carapace of beetles, organs of molluscs, and the cell walls of fungi such as molds, yeasts, and mushrooms. And in the living body, it exists in a combined form of carbohydrate and protein. Because chitin forms the outer shell of living things, in 1823 the French scientist Ogilzii named it chitin, which means envelope in Greek. Chitin is not broken down by human digestive enzymes, so it has properties similar to dietary fiber to some extent.

도 2는 본 발명의 키토산 섬유의 구조도이다. 본 발명의 일 실시예에 따른 무전원 중력방식 정수기용 필터는 키토산섬유이다. 키토산섬유는 속이 비어있는 중공섬유일 수 있다. 키토산섬유에 화학처리를 통해 성능을 향상 시킬 수 있다. Figure 2 is a structural diagram of the chitosan fiber of the present invention. The filter for a non-powered gravity type water purifier according to an embodiment of the present invention is chitosan fiber. The chitosan fibers may be hollow fibers. Performance can be improved through chemical treatment of chitosan fibers.

키토산섬유를 사용하면, 중금속 제거, 잔류염소, 화학물질 제거를 동시에 할 수 있어 다른 소재를 넣을 필요가 없으므로, 필터 제조 공정이 단순해진다는 장점이 있다. 본 발명에서의 정수필터(10)의 두께는 10㎜ 내지 100㎜범위이다. If chitosan fiber is used, heavy metal removal, residual chlorine, and chemical substances can be removed at the same time, so there is no need to add other materials, which has the advantage of simplifying the filter manufacturing process. The thickness of the water filter 10 in the present invention is in the range of 10 mm to 100 mm.

필터의 두께가 10㎜보다 작을 경우 유속이 너무 지나치게 빨라져서 중금속 등의 이물질과 접촉을 거의 하지 못하고 통과되므로 제거율이 낮아지게 되는 문제가 있다. 필터의 두께가 100㎜보다 클 경우 유속이 지나치게 느려져서 대기시간이 길어지므로 사용성에 있어서 문제가 된다. When the thickness of the filter is less than 10 mm, the flow rate is too fast and passes through hardly contact with foreign substances such as heavy metals, so there is a problem that the removal rate is lowered. When the thickness of the filter is greater than 100 mm, the flow rate becomes too slow and the waiting time becomes long, which is a problem in usability.

이를 각 층별로 구분하여 보면, 최선의 실시예는 활성탄층(12)은 1㎜ 내지 50㎜이고, 이온교환수지층(11)은 5㎜ 내지 70㎜ 및 키토산섬유층(13)은 1㎜ 내지 10㎜ 범위인 것이 바람직하다. 상기 키토산섬유층(13)은 피치(pitch) 등의 유기물을 섬유로 만든 다음 특수한 열처리 공정을 거쳐 만들어지는 탄소섬유를 활성화시켜 제조한 키토산섬유를 포함한. 키토산섬유는 무수히 많은 미세공(micropore)으로 형성된다. 따라서, 흡착용량이 크며, 미세공이 표면에 발달되어 있기 때문에 흡착속도가 매우 빠르다. 특히, 유리잔류염소, 트리할로메탄류, 클로로포름 등 휘발성 유기화합물(VOC), 납 등을 효과적으로 흡착할 수 있다. 또한 아민 냄새 제거, 메틸메르 캅탄 제거 능력을 가지고 있다. If you look at this for each layer, the best embodiment is that the activated carbon layer 12 is 1 mm to 50 mm, the ion exchange resin layer 11 is 5 mm to 70 mm, and the chitosan fiber layer 13 is 1 mm to 10 mm. It is preferably in the mm range. The chitosan fiber layer 13 includes chitosan fibers manufactured by activating carbon fibers made by making organic materials such as pitch into fibers and then going through a special heat treatment process. Chitosan fibers are formed with countless micropores. Therefore, the adsorption capacity is large and the adsorption rate is very fast because the micropores are developed on the surface. In particular, it can effectively adsorb free residual chlorine, trihalomethanes, volatile organic compounds (VOCs) such as chloroform, and lead. It also has the ability to remove amine odor and remove methyl mercaptan.

본 발명의 다른 실시예에서 키토산섬유는 카드뮴, 철, 구리와 같은 중금속 이온들에 대한 흡착 능력은 매우 약하다. 이러한 중금속 이온들을 제거하기 위해 키토산섬유를 이용하여 표면개질할 경우 카드뮴, 철, 구리의 흡착량 및 흡착속도가 개선된다. 본 발명의 일 실시예에 따른 키토산섬유를 이용한 정수기용 필터는 통수 속도가 두 배 이상 개선됨과 동시에 중금속 제거율도 우수하다. In another embodiment of the present invention, chitosan fibers have very weak adsorption capacity for heavy metal ions such as cadmium, iron, and copper. When the surface is modified using chitosan fiber to remove these heavy metal ions, the adsorption amount and adsorption rate of cadmium, iron, and copper are improved. The filter for water purifier using chitosan fiber according to an embodiment of the present invention is excellent in the rate of heavy metal removal at the same time as the water passing speed is improved more than twice.

또한 본 발명의 키토산섬유를 이용한 정수필터는 종래의 중력방식 필터에 비하여 우월한 정수 효과가 있다.In addition, the water purification filter using the chitosan fiber of the present invention has a superior water purification effect compared to the conventional gravity filter.

이상에서 본 발명의 바람직한 실시예를 설명하였으나, 본 발명의 실시예와 실질적으로 균등한 범위까지 본 발명의 권리범위가 미치는 것으로 해석되어야 하며, 본 발명의 기술사상 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시가 가능하다.Although preferred embodiments of the present invention have been described above, it should be construed that the scope of the present invention extends to a range substantially equivalent to the embodiments of the present invention, and within the technical spirit of the present invention, the technical field to which the present invention belongs Various modifications are possible by those of ordinary skill in the art.

본 발명의 키토산섬유를 이용한 정수필터가 종래의 중력방식 필터에 비해 우월한 정수 효과가 있으므로 정수기용 필터 산업에 매우 유용한 발명이다.Since the water-purifying filter using the chitosan fiber of the present invention has a superior water-purifying effect compared to the conventional gravity filter, it is a very useful invention in the filter industry for water purifiers.
