This is a widely preferred water purification device.
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, contact time is important because conventional gravity water purification devices adsorb contaminants through electrostatic attraction through ion exchange. Therefore, the faster the flow rate, the lower the pollutant removal performance, and it was difficult to satisfy both a fast water purification rate and a high heavy metal removal rate at the same time.

도 1은 본 발명의 일실시예에 따른 활성탄소섬유와 칼슘미네랄입자를 이용한 소형 정수필터의 단면도이다.Figure 1 is a cross-sectional view of a small water purification filter using activated carbon fiber and calcium mineral particles according to an embodiment of the present invention.
도 1에 도시된 바와 같이, 본 발명의 일 실시예에 따른 소형 정수필터(10)는 위에서부터 제1면섬유층(14: Natural pulp fiber), 칼슘미네랄층(11: Calcium Minerals), 활성탄소입자층(12: AC(Carbon graules)), 활성탄소섬유층(13: ACF(Cabon fiber)) 및 제2면섬유층(15: Natural pulp fiber) 순서대로 적층되어 구성된다. As shown in Figure 1, the small water purification filter 10 according to an embodiment of the present invention includes, from the top, a first cotton fiber layer (14: Natural pulp fiber), a calcium mineral layer (11: Calcium Minerals), and an activated carbon particle layer. (12: AC (Carbon graules)), activated carbon fiber layer (13: ACF (Cabon fiber)), and second cotton fiber layer (15: Natural pulp fiber) are laminated in that order.
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 turning organic materials such as acrylic resin and pitch obtained from petroleum or coal into fiber and then activating the carbon fiber through a special heat treatment process. Compared to activated carbon, activated carbon fiber consists mostly of micropores.
활성탄소섬유는 환경 활성탄의 흡착 성능을 향상시키기 위하여 섬유의 형태로 가공한 물질. 접착 섬유, 폴리아크릴로니트릴 섬유, 피치계 탄소 섬유 등이 있다. 활성탄소섬유는 흡착ㆍ탈착 속도가 빠르고 정화 효과가 뛰어나 유기 폐가스를 효과적으로 처리할 수 있고, 기공 크기가 비교적 균일하여 분자체 효과가 뛰어나고, 섬유 직경(6~10㎛)이 작아서 균일한 흡착 특성을 얻을 수 있다. Activated carbon fiber is a material processed into a fiber form to improve the adsorption performance of environmental activated carbon. There are adhesive fibers, polyacrylonitrile fibers, pitch-based carbon fibers, etc. Activated carbon fiber has a fast adsorption and desorption speed and an excellent purification effect, so it can effectively treat organic waste gas. Its pore size is relatively uniform, so it has an excellent molecular sieve effect, and its small fiber diameter (6~10㎛) provides uniform adsorption characteristics. You can get it.
또한 활성탄소섬유는 내부기공이 모두 외부 표면에 직접 연결되어 있어서 물질 전달 속도가 매우 빠르고, 인장강도와 탄성률이 우수하며, 열/전기전도도, 밀도 등의 물성 조절이 쉽고, 내열성, 내부식성, 내층격성이 우수하고, 고온에서의 열팽창 수축이 거의 없는 성질 등 활성탄에 비해 매우 우수한 특성이 있다. In addition, activated carbon fiber has all internal pores directly connected to the external surface, so the mass transfer speed is very fast, the tensile strength and elastic modulus are excellent, and physical properties such as thermal/electrical conductivity and density can be easily adjusted, as well as heat resistance, corrosion resistance, and inner layer. It has excellent properties compared to activated carbon, including excellent toughness and almost no thermal expansion or contraction at high temperatures.
본 발명의 일실시예에서 바람직한 활성탄소입자층(12)의 두께는 5~30mm인 것이 특징이다. In one embodiment of the present invention, the thickness of the activated carbon particle layer 12 is preferably 5 to 30 mm.
탄산칼슘(calcium carbonate)은 대리석·방해석·조개껍데기·달걀껍데기·산호 등에서 산출되는 무기 화합물이다. 탄산칼슘은 화학식 CaCO3으로 자연계에 존재하는 염 중에서 가장 많고, 일반적으로 무색의 결정 또는 백색 고체로, 비중 2.93이며, 825℃에서 분해한다. 탄산칼슘은 가열하면 이산화탄소를 발생하고 생석회를 얻는다. Calcium carbonate is an inorganic compound produced from marble, calcite, seashells, eggshells, corals, etc. Calcium carbonate, with the chemical formula CaCO3, is the most abundant salt in nature and is generally a colorless crystal or white solid with a specific gravity of 2.93 and decomposes at 825°C. When calcium carbonate is heated, it generates carbon dioxide and quicklime is obtained.
탄산칼슘 반응은 이산화탄소와 생석회를 공업적으로 얻기 위한 중요한 반응이다. 화학식 CaCO3 → CaO＋CO2↑ 순수한 물에는 용해하지 않으나, 이산화탄소를 함유하는 물에는 용해하여, 탄산수소칼슘을 생성하며 녹는다. CaCO3＋CO2＋H2O ↔ Ca(HCO3)2 또, 탄산칼슘에 산을 작용시키면 이산화탄소를 발생한다.Calcium carbonate reaction is an important reaction for obtaining carbon dioxide and quicklime industrially. Chemical formula CaCO3 → CaO＋CO2↑ It is insoluble in pure water, but dissolves in water containing carbon dioxide, producing calcium bicarbonate. CaCO3＋CO2＋H2O ↔ Ca(HCO3)2 Also, when acid acts on calcium carbonate, carbon dioxide is generated.

In the best embodiment shown in Figure 1, the thickness of the calcium mineral layer 11 is 10 to 30 mm, the thickness of the activated carbon particle layer 12 is 5 to 30 mm, and the thickness of the activated carbon fiber layer 13 is 3 to 10 mm. .
도 2는 본 발명의 일실시예에 따른 소형 정수필터의 구조도이다. Figure 2 is a structural diagram of a small water purification filter according to an embodiment of the present invention.
본 발명의 일실시예에 따른 소형 정수필터는 위에서부터 제1면섬유층, 칼슘미네랄층, 활성탄소입자층, 활성탄소섬유층 및 제2면섬유층으로 구성된다. A small water purification filter according to an embodiment of the present invention is composed of a first cotton fiber layer, a calcium mineral layer, an activated carbon particle layer, an activated carbon fiber layer, and a second cotton fiber layer from the top.
상기 칼슘미네랄층에 Cd2+, Pb2+, Cu2+, Zn2+ 이 제거된다. 상기 활성탄소입자층에 향료(Odor), 유기물(Organics) 및 염소(Chlorine)가 제거되고, 상기 활성탄소섬유층에도 향료, 유기물 및 염소가 제거된다. Cd2+, Pb2+, Cu2+, and Zn2+ are removed from the calcium mineral layer. Odors, organics and chlorine are removed from the activated carbon particle layer, and fragrances, organic substances and chlorine are also removed from the activated carbon fiber layer.
본 발명의 일실시예에 따른 활성탄소섬유와 칼슘미네랄입자를 이용한 소형 정수필터는 키토산섬유를 사용한다. 상기 키토산섬유는 속이 비어있는 중공섬유일 수 있다. 키토산섬유에 화학처리를 통해 성능을 향상 시킬 수 있다. A small water purification filter using activated carbon fiber and calcium mineral particles according to an embodiment of the present invention uses chitosan fiber. The chitosan fiber may be a hollow fiber. The performance of chitosan fiber can be improved through chemical treatment.
키토산섬유를 사용하면, 중금속 제거, 잔류염소, 화학물질 제거를 동시에 할 수 있어 다른 소재를 넣을 필요가 없으므로, 필터 제조 공정이 단순해지는 장점이 있다. 키토산섬유는 무수히 많은 미세공(micropore)으로 형성되므로 흡착용량이 크며, 미세공이 표면에 발달되어 있기 때문에 흡착속도가 매우 빠르다. 이는 유리잔류염소, 트리할로메탄류, 클로로포름 등 휘발성 유기화합물(VOC), 납 등을 효과적으로 흡착할 수 있다. 또한 아민 냄새 제거, 메틸메르 캅탄 제거 능력을 가지고 있다. Using chitosan fiber has the advantage of simplifying the filter manufacturing process because it can remove heavy metals, residual chlorine, and chemicals at the same time, eliminating the need to add other materials. Chitosan fiber has a large adsorption capacity because it is formed of countless micropores, and because the micropores are developed on the surface, the adsorption speed is very fast. It can effectively adsorb free residual chlorine, trihalomethanes, volatile organic compounds (VOCs) such as chloroform, lead, etc. It also has the ability to remove amine odor and methyl mercaptan.
본 발명의 일실시예에서 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 일실시예에 따른 활성탄소섬유와 칼슘미네랄입자를 이용한 소형 정수필터는 통수 속도가 두 배 이상 개선됨과 동시에 중금속 제거율도 우수하다. In one embodiment of the present invention, chitosan fiber has a very weak adsorption ability 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. A small water purification filter using activated carbon fiber and calcium mineral particles according to an embodiment of the present invention improves the water flow rate by more than two times and also has an excellent heavy metal removal rate.
또한 본 발명의 활성탄소섬유와 칼슘미네랄입자를 이용한 소형 정수필터는 무전원 중력방식 정수기용 필터에 비해 우월한 정수 효과가 있다.In addition, the small water purification filter using activated carbon fiber and calcium mineral particles of the present invention has a superior water purification effect compared to filters for non-powered gravity water purifiers.

본 발명의 활성탄소섬유와 칼슘미네랄입자를 이용한 소형 정수필터는 가격이 저렴한 칼슘미네랄 입자를 사용함으로 필터 제조 원가를 절감할 수 있는 효과가 있으므로 정수기용 필터 산업에 매우 유용한 발명이다.The small water purification filter using activated carbon fiber and calcium mineral particles of the present invention is a very useful invention in the water purifier filter industry because it has the effect of reducing filter manufacturing costs by using inexpensive calcium mineral particles.
