Abstract:
처리 용량을 늘릴 수 있는 CDI 타입의 연수기가 개시된다. 본 발명에 따른 연수기는 경수가 유입되고 연수화된 경수가 배출되는 챔버와, 챔버 내부에 복수개가 적층 마련되되 양전압과 음전압이 교대로 인가되는 전극부를 포함하는 연수기에 있어서, 전극부를 콘 형상으로 마련하거나 또는 구동부재를 이용하여 회전시킴으로써, 연수 동작시에는 전극부와 경수 사이의 접촉 시간(표면적 또는 거리)을 연장시켜 이온의 흡착량을 늘리고, 재생 동작시에는 전극부와 경수 사이의 접촉 시간(또는 거리)을 상대적으로 단축시킴으로써 탈착량을 늘리기 때문에, 단위 시간에 처리할 수 있는 유량이 종래에 비해 상대적으로 증가된다.
Abstract:
본 발명의 목적은 방사성을 향상시키기 위해 정전방사법을 최적화시켜 탄소섬유의 직경을 작게 할 수 있는 폴리이미드 탄소나노섬유 전극 및 탄소나노튜브 복합체 전극의 제조방법을 제공하는 것이다. 개시된 본 발명에 의한 탄소섬유전극의 제조방법은 PMDA(PryoMellitic DiAnhydride)와 ODA(OxyDiAniline)를 단량체로 하고 TEA(TriEtylAmine)를 촉매로 하여 PI(PolyImide) 전구체인 PAA(PolyAmicAcid)를 합성하는 단계, 상기 PAA(PolyAmicAcid)용액에 DMF(DiMethylFormamide)을 넣어 방사용액을 제조하고 고전압으로 정전 방사하여 PAA 나노섬유종이를 얻는 단계, 상기 PAA 나노섬유종이를 열처리하여 PI(PolyImide)로 전환하는 단계, 상기 PI(PolyImide) 나노섬유종이를 불활성가스 분위기에서 열처리하여 CNF(CarbonNanoFiber)로 전환하는 단계를 포함하여 이루어진다.
Abstract:
A washing machine equipping with a water softener is provided to generate softened water without causing environment pollution. A washing machine equipping with a water softener comprises a housing(10), a door(12) opening and closing a laundry inlet(11); a water tub(14) having a washing chamber into which the laundry is placed; a water supply device(16) supplying water into the washing chamber; and a drain device(17) draining washing water of a washing chamber(13). The water softener is installed inside the housing.
Abstract:
A water softener is provided to shorten an interval between electrode units by a squeeze unit to help desorption of ion absorbed in the electrode unit, thereby relatively increasing liquid capacity which can be treated within unit time. Hard water is flowed into a chamber(10) and softened water is discharged. Electrode units(20,30) are stacked in the chamber by a predetermined interval. Positive and negative voltages are alternately applied to the electrode unit. Ion of hard water is absorbed in the electrode unit during water softening operation and desorbed during regenerating operation. A squeeze unit shortens an interval between electrode units during the regenerating operation.
Abstract:
A capacitive deionization type water softener is provided to extend contact time between an electrode unit and hard water during water softening operation so as to increase an absorption amount of ion and reduce the contact time so as to increase a desorption amount. Hard water is flowed into a chamber(10) and softened water is discharged. A plurality of electrode units(20) is stacked in the chamber. Positive and negative voltages are alternately applied to the electrode unit. The electrode unit has a cone shape.
Abstract:
A water softening apparatus is provided to increate the treatment amount by respectively moving materials of anions and cations to the spaces between first and second net electrodes and discharging the materials with water. A plate typed net electrodes plural permeable holes(11a), and the plural permeable holes enable the permeability of anionic materials. Net electrodes(11,12) are arranged, being separated. A positive pole power is applied to first net electrodes(11) which has a pair of power sources. A pair of second net electrodes(12) are arranged, being separated. A negative power is applied to the pair of second net electrodes.
Abstract:
A water softener and a home appliance including the same are provided to remove the scale piled up in the pipe inner wall by ionizing the magnesium and calcium, etc. of hydroxide. A pipe(10) has magnetism, and a magnet(20) is prepared inside the pipe. A whirlpool forming unit(22,23) magnetizes water by forming whirlpool. A plurality of tapered portions(21) diameter increases the flow direction of the fluid.
