본 발명은 광촉매 이산화티탄이 코팅된 3차원 세라믹 필터를 포함하는 정수 하우징에 관한 것이다.The present invention relates to a water purification housing comprising a three-dimensional ceramic filter coated with photocatalyst titanium dioxide.
아파트 또는 공동 물탱크, 산업 현장 물탱크 및 단독주택의 FRP 물탱크 내의 저장된 물은 공기 속의 세균의 침투로 인하여 물속의 녹조류의 번식, 각종 세균 및 바이러스의 2차 번식이 심하다. 때때로, 물탱크 청소를 위해 용역사업에 의뢰하곤 하는 현실이다.Stored water in apartment or communal water tanks, industrial water tanks and FRP water tanks in single-family homes are prone to green algae breeding and secondary breeding of various bacteria and viruses due to the infiltration of bacteria in the air. Occasionally, the project is commissioned to clean the water tank.
탱크 내부의 방수 도장이나 RFP 자체는 다이옥신, 벤젠 등 발암성 유기물질과 환경 호르몬의 유출로 성장 어린이에게 심한 장애를 일으키는 문제를 야기한다.The waterproof coating inside the tank or the RFP itself causes serious problems for growing children due to the leakage of carcinogenic organic substances such as dioxins and benzene and environmental hormones.
한편, 1970년대 빛에 의해 활성화된 이산화티탄에 의해 물이 분해되는 현상이 보고되었다. 이 현상을 기초로 이산화티탄의 코팅막이나 복합 재료 등이 개발되어 물처리 기술 및 오염방지 기술에 응용되기 시작하였다. 관촉매는 빛의 에너지에 의해 활동하는 촉매라고 할 수 있다. 이 광촉매는 빛을 흡수해 에너지의 높은 상태가 되어 그 에너지를 반응 대상이 되는 물질에 부여해 화학반응을 일으켜 각종 정화작용을 수행하게 된다.Meanwhile, a phenomenon in which water is decomposed by titanium dioxide activated by light in the 1970s has been reported. Based on this phenomenon, titanium dioxide coating film or composite material was developed and applied to water treatment technology and pollution prevention technology. The catalyst is a catalyst that is activated by the energy of light. The photocatalyst absorbs light and becomes a high energy state, and the energy is applied to a substance to be reacted to cause a chemical reaction to perform various purification functions.
1990년대 이산화티탄 광촉매가 질소산화물의 분해 정화에 적용가능하다는 보고가 있었다. 광촉매의 환경 정화재료에의 이용 및 상품화를 가속화함과 함께 이산화티탄막 표면을 다공질화한 코팅이나 인회석과 복합한 다기능 복합재료 등도 개발되었다. 최근에는 가시광 응답형 광촉매의 개발도 진행하고 있다.In the 1990s, there have been reports that titanium dioxide photocatalysts are applicable to the decomposition and purification of nitrogen oxides. In addition to accelerating the commercialization and commercialization of photocatalysts, coatings with porous surfaces of titanium dioxide films and multifunctional composites combined with apatite were also developed. Recently, the development of visible light responsive photocatalysts is also in progress.
광촉매에는 금속, 반도체, ZnO, CdS, ZrO2, SnO2, WO3 등과 페롭스카이트형 복합금속산화물인 SrTiO3 등이 있으나, 모든 유기물을 이산화탄소와 물로 분해할 수 있는 능력을 갖고 있는 이산화티탄이 대표적인 광촉매 물질로 널리 사용되고 있다. 그 중에서, 광촉매 반도체의 이산화티탄 (아나타제 및 루틸형)은 물에 분해되지 않고, 저가로 내구성 및 내마모성이 우수하며, 자원 측면에서도 풍부하여 입수하기 쉬운 유리한 조건 등으로 인해 현재 가장 많이 사용되고 있는 촉매이다. 이산화티탄 결정 중에서 특히 아나타제가 광촉매로서 가장 많이 사용되고 있다. 이산화티탄에 빛을 투여할 때 발생하는 강력한 산화력을 이용하면, 독성이 매우 높은 다이옥신을 포함하여 거의 모든 유기물질을 물이나 탄산가스로 분해할 수 있다. 이 광촉매 작용을 이용함으로써 탈취, 항균 및 공팡이 방지, 배기가스의 정화, 오염 방지, 셀프 클리닝, 물처리 등 환경 분야에의 폭넓은 응용이 가능하다.Photocatalyst include, but are metals, semiconductors, ZnO, Cd S, ZrO 2, SnO 2, WO 3 as perop Perovskite - Type composite metal oxide of SrTiO 3, a titanium dioxide in all organisms have the ability to decompose carbon dioxide and water It is widely used as a representative photocatalyst material. Among them, titanium dioxide (Anatase and rutile type) of photocatalytic semiconductors are the most widely used catalysts because they are not decomposed to water, have excellent durability and abrasion resistance at low cost, and are advantageous in terms of resources and are easy to obtain. . Among the titanium dioxide crystals, in particular, anatase is most often used as a photocatalyst. Using the strong oxidizing power generated by the administration of light to titanium dioxide, it is possible to decompose virtually all organic matter, including toxic dioxins, into water or carbon dioxide. By utilizing this photocatalytic action, a wide range of applications to environmental fields such as deodorization, antibacterial and mold prevention, exhaust gas purification, pollution prevention, self cleaning and water treatment are possible.
따라서, 아파트 또는 공동 물탱크 등에 저장된 물의 오염 등을 방지하기 위한 정수 시스템이 요구되고 있는 현실에서 광촉매 등을 이용하여 우수한 정수 효과를 제공하는 기술 개발에 대한 현실적인 필요성이 존재하고 있다.Therefore, there is a real need for the development of a technology for providing an excellent water purification effect using a photocatalyst, etc. in the reality that a water purification system for preventing contamination of water stored in an apartment or a shared water tank or the like is required.
본 발명의 목적은 상기 필요성을 충족시키기 위해 아파트 또는 공동 물탱크 등에 저장된 물의 오염 등을 방지하기 위한 것으로서, 광촉매 이산화티탄이 코팅된 3차원 세라믹 필터를 이용한 정수 하우징을 제공하는 것이다.An object of the present invention is to provide a water purification housing using a three-dimensional ceramic filter coated with titanium dioxide photocatalyst to prevent the contamination of water stored in an apartment or a shared water tank, etc. in order to meet the above needs.
따라서, 본 발명은 광촉매 이산화티탄이 코팅된 3차원 세라믹 필터를 포함하는 정수 하우징에 관한 것이다.Accordingly, the present invention relates to a water purification housing comprising a three-dimensional ceramic filter coated with photocatalyst titanium dioxide.
보다 구체적으로, 본 발명의 정수 하우징은 유리에 석영 미립자 또는 보로실리케이트를 혼합하여 그 표면에 다수의 홀이 존재하도록 성형된 하우징, 3차원 미 세 셀 Si/Sic (Si+카보네이트) 다공질 세라믹 필터 및 하우징 내부에 배치된 UV 램프를 포함한다.More specifically, the water purification housing of the present invention is a housing formed by mixing quartz fine particles or borosilicate in glass and having a plurality of holes on the surface thereof, a three-dimensional microcell Si / Sic (Si + carbonate) porous ceramic filter and housing UV lamps disposed therein.
