본 발명은 공기청정기용 활성탄필터에 관한 것으로써, 특히, 활성탄본체에는 항균물질이 포함되어, 활성탄에 흡착된 악취물질 및 미세유기물질의 미생물 반응에 의한 부패취 발생을 억제할 수 있는 공기청정기용 활성탄필터에 관한 것이다.The present invention relates to an activated carbon filter for an air cleaner, and in particular, the activated carbon body contains an antibacterial material, which can suppress the generation of odor caused by the microbial reaction of odorous substances and microorganisms adsorbed on the activated carbon. It relates to an activated carbon filter.
종래의 공기청정기용 활성탄필터는 한국등록특허 제507996호에 제시된 것이 있다.Conventional activated carbon filters for air cleaners are those disclosed in Korean Patent No. 507996.
일반적으로 근래에 들어 실외보다 실내가 더 오염되고 있는 것으로 알려져 있다. 이것은 거주환경에 따른 것으로, 기밀성높은 고단열 주택이나 아파트는 냉난방효과를 높이는 장점이 있으나, 반면 실내공기가 오염되었을 경우 그 오염물질이 장시간 실내에 잔존하게 되는 단점이 있다. 성인이 하루 평균 20시간을 실내에서 생활함을 감안할 때, 이러한 실내오염은 진지하게 고려되어야 할 것이다.In general, indoors are known to be more polluted than to be outdoors. This is due to the living environment, the air-tight high-insulation houses or apartments have the advantage of improving the heating and heating effect, while the indoor air is polluted, the contaminants remain in the room for a long time. Given that adults live indoors an average of 20 hours a day, this indoor pollution should be taken seriously.
상기와 같은 실내오염 물질은 약 100㎛ 이상의 강하성 먼지부터 부유오염물질인 10~100㎛ 정도의 꽃가루나 25㎛ 정도의 미세먼지, 10㎛ 정도의 곰팡이나 진드기 부산물, 0.001~1㎛ 정도의 담배연기 등을 들 수 있다.Such indoor pollutants include pollutants of about 100 μm or more from pollutants of about 100 μm or more, pollen of about 10 to 100 μm, fine dust of about 25 μm, by-products of mold or mites of about 10 μm, tobacco of about 0.001 to 1 μm Smoke etc. can be mentioned.
이러한 실내오염물질이나 악취를 제거하기 위해 공기정화기가 개발되어 있으며, 공기정화기는 그 방식에 따라 크게 기계집진식과 전기집진식으로 구분된다.An air purifier has been developed to remove such indoor pollutants or odors. The air purifier is classified into a mechanical dust collection type and an electric dust collection type according to the method.
더욱 상세하게는 미립자제거방식과 악취제거방식에 의해 세분류되어, 미립자 제거방식에 따라 전기식 여과방식, 전기침전방식, 음이온발생방식, 기계적필터방식으로 구분되며, 악취제거방식에 따라 오존발생방식과 카본흡착방식등으로 구분된다.More specifically, it is subdivided into fine particle removal method and odor removal method, and classified into electric filtration method, electroprecipitation method, anion generation method, and mechanical filter method according to particle removal method, and ozone generation method and carbon according to odor removal method. It is divided into adsorption method.
이 중 전기집진식은 코로나 방전에 의한 음이온화 영역에서 공기중 부유물을 대전시켜 집진을 수행토록 한 것이다.Among these, the electrostatic precipitating method is to charge dust in the air in the anionized region by corona discharge to perform the dust collection.
즉, 방전에 의한 이온화 영역을 생성하고 여기에 공기를 통과시키면서, 방전에 의해 세균등을 제거함과 더불어 미세물질의 대전에 의해 양극판이 집진을 수행토록 한 것이다.That is, while generating ionization regions by discharge and passing air therethrough, the discharge of bacteria and the like is eliminated by discharge, and the positive electrode plate is collected by the charging of fine materials.
한편, 기계식은 각 기능을 갖는 필터를 조합하여 사용하는 것으로, 예를 들어 카본흡착필터와 미립자제거필터를 조합하여 카본흡착필터로 악취를 제거하고 미립자제거필터로 균이나 미세분진이 제거되도록 한 것이다.On the other hand, the mechanical type is to use a combination of filters having each function, for example, by combining a carbon adsorption filter and a particle removal filter to remove odors with a carbon adsorption filter and to remove bacteria and fine dust with a particle removal filter. .
이러한 필터로는 단순히 큰 먼지를 걸러주는 부직포필터, 공기중의 악취 및 냄새를 제거하는 활성탄필터, 곰팡이균이나바이러스균등의 각종 세균을 제거하는 항균필터, 반도체회사의 크린룸에서 사용하는 특수섬유로 제작하여 미세먼지를 걸러주는 헤파필터등이 이용된다.These filters are made of non-woven fabric filters that filter out large dust, activated carbon filters to remove odors and odors in the air, antibacterial filters to remove various bacteria such as fungi and viruses, and special fabrics used in clean rooms of semiconductor companies. Hepa filter for filtering fine dust is used.
종래의 이와 같은 활성탄은 벤젠, 톨루엔 등과 같은 무극성의 탄화수소류 흡착에 사용되고 있으나 암모니아를 포함하는 악취가스에는 충분하지 못하여 산 및 알칼리금속 할라이드 혼합물을 담지시킨 탈취제가 사용되고 있다. Conventionally, such activated carbon is used for adsorption of nonpolar hydrocarbons such as benzene and toluene. However, deodorant in which acid and alkali metal halide mixtures are supported is not used for odor gas containing ammonia.
이와 같이 활성탄에 산 및 알칼리금속 할라이드 혼합물을 담지시킨 것은 한국등록특허 제33545호에 제시되어 있다.The support of the acid and alkali metal halide mixture on the activated carbon is presented in Korean Patent No. 33545.
그러나, 이러한 활성탄의 미세기공을 포함한 표면을 산 및 알칼리금속 할라이드로 첨착처리할 경우, 반데르발스(van der waals) 힘이 약화되어 일반활성탄에 비해 많은 양의 암모니아를 흡착처리할 수 있다.However, when the surface containing the micropores of activated carbon is impregnated with an acid and an alkali metal halide, van der Waals forces are weakened, so that a large amount of ammonia can be adsorbed compared to general activated carbon.
활성탄표면에 암모니아 등이 흡착될 경우 활성탄은 암모니아로 포화되며, 이러한 암모니아는 미생물의 에너지원으로 사용된다. 암모니아는 질산화박테리아의 전자공여체역할을 수행하고 미세기공내에 산소농도가 낮을 경우 혐기성 반응이 수반되어 황산화물의 합성이 이루어짐으로써 악취발생원으로 작용하는 문제점이 있다.When ammonia or the like is adsorbed on the surface of activated carbon, the activated carbon is saturated with ammonia, which is used as an energy source for microorganisms. Ammonia has a problem in that it acts as an odor source by performing an electron donor role of nitrate and having an anaerobic reaction when the oxygen concentration in the micropores is low, thereby synthesizing sulfur oxides.
본 발명은 전술한 문제를 해결하기 위하여 안출된 것으로, 활성탄본체에는 항균물질이 포함되어, 활성탄에 흡착된 악취물질 및 미세유기물질의 미생물 반응에 의한 부패취 발생을 억제할 수 있는 공기청정기용 활성탄필터를 제공하는데 그 목적이 있다.

본 발명의 바람직한 실시예에 따른 공기청정기용 활성탄필터 제조방법은, 활성탄을 은염수용액에 침지시키는 제1침지단계와, 인산과 구연산을 혼합한 혼합수용액과 브롬화칼륨수용액을 혼합한 용액에 상기 활성탄을 침지시키는 제2침지단계와, 상기 활성탄을 고온에서 가열하는 가열단계를 포함하여 이루어지는 것을 특징으로 한다.In the method of manufacturing an activated carbon filter for an air cleaner according to a preferred embodiment of the present invention, the activated carbon is immersed in a silver saline solution, a mixed solution of phosphoric acid and citric acid and a solution of potassium bromide solution. And a heating step of heating the activated carbon at a high temperature.
이 구성에 의하면, 손상된 활성탄의 기공을 부활시킬 수 있다. According to this structure, the pore of the damaged activated carbon can be revived.
전술한 구성에서, 상기 제1침지단계에서, 상기 은염수용액은 수용성 질산은의 은염 또는 염화은의 은염과 증류수를 혼합하여 제조한다.In the above configuration, in the first immersion step, the silver salt solution is prepared by mixing silver salt of water soluble silver nitrate or silver salt of silver chloride with distilled water.
상기 가열단계에 이어서, 상기 활성탄을 냉각하는 냉각단계와, 상기 제1침지단계 이전에, 야자껍질을 활성화시켜 상기 활성탄을 제조하는 제조단계와, 상기 활성탄에 산과 알칼리금속 할라이드의 혼합물을 담지시키는 담지단계를 더 포함하여, 활성탄의 암모니아 제거효율은 높도록 유지하면서 유기물질과 미생물의 반응에 의한 부패취 발생을 억제할 수 있다.Following the heating step, a cooling step of cooling the activated carbon, a manufacturing step of activating a palm shell to prepare the activated carbon before the first immersion step, and a support for supporting a mixture of an acid and an alkali metal halide on the activated carbon.

참고적으로, 이하에서 설명될 본 발명의 구성들 중 종래기술과 동일한 구성에 대해서는 전술한 종래기술을 참조하기로 하고 별도의 상세한 설명은 생략한다.For reference, among the configurations of the present invention to be described below, the same configuration as the prior art will be referred to the above-described prior art, and a detailed description thereof will be omitted.
본 실시예의 공기청정기용 활성탄필터는, 활성탄본체를 포함하되, 상기 활성탄본체에는 항균물질이 포함된다.The activated carbon filter for an air cleaner of the present embodiment includes an activated carbon body, and the activated carbon body includes an antibacterial substance.

활성탄본체에는 은분말, 나노크기의 은입자, 은나노와 같은 항균물질이 첨착 담지되어 포함된다.The activated carbon body includes silver powder, nano-sized silver particles, and an antimicrobial substance such as silver nano impregnated supported.
나아가, 활성탄본체는 암모니아 흡착능을 증대시키기 위해 알칼리금속 할라이드(예;브롬화 칼륨)의 산의 혼합물(화학적 첨착담지방법)을 첨착 담지시키는 것이 바람직하다.Furthermore, it is preferable that the activated carbon is impregnated with a mixture of an alkali metal halide (eg, potassium bromide) acid (chemical impregnation supporting method) in order to increase the ammonia adsorption capacity.
이와 같이 활성탄본체에 은나노를 첨착 담지하면 은나노가 항균작용을 하여 활성탄본체에서 미생물 반응이 생기는 것을 방지하게 된다.In this way, silver nano impregnation of the activated carbon body prevents silver nanoparticles from causing microbial reaction in the activated carbon body.
은첨착 악취제거용 활성탄과 화학적 첨착담지방법에 따른 활성탄을 각각 소형반응조에 넣고 암모니아 가스를 공급하면서 제거효율과 운전에 따른 활성탄표면의 미생물 성장특성과, 활성탄에서 발생되는 악취특성을 실험하였다.Activated carbon for removing silver odor and activated carbon according to chemical impregnation method were put into small reactor, and ammonia gas was supplied, and microbial growth characteristics of activated carbon surface and odor characteristics generated from activated carbon were tested.
