Abstract

The present invention relates to a method of purifying air indoors or outdoors by using an air purifier, which is manufactured by mounting a low temperature catalyst of composite metal oxide, which initiates oxidation at a relatively low temperature with various volatile organic compounds such as sick house syndrome substances. The air purifier completely decomposes and removes volatile organic compounds, ammonia, bad smells and other harmful components existing indoors or outdoors in a decomposition and removal method by a catalyst reaction, not in an adsorption and removal method by conventional adsorption methods. Accordingly, when the air purifier is used indoors, the air around the product and the indoor air can be always maintained clean, and when the air purifier is used in an industrial site generating harmful component gas, the air quality in the working place can be remarkably improved. Furthermore, the apparatus of the present invention is manufactured horizontally so as to be used by installing the apparatus in a large or small scale as an air pollution control system.

Description

복합금속산화물 저온촉매를 이용한 공기정화기 또는 대기오염방지시설{Air purifier or air pollution control system using composite metal oxide low temperature catalyst}TECHNICAL FIELD [0001] The present invention relates to an air purifier or an air pollution control system using a composite metal oxide low temperature catalyst,

본 발명은 가정이나 각종 산업현장 그리고 일반건물의 사무실 등 실내에서 발생하는 유해가스를 제거하기 위해 종래의 흡착방법이 아닌 복합금속산화물 저온촉매를 사용하여 유해가스를 인체에 무해한 이산화탄소와 물 그리고 질소로 완전분해 제거하는 공기정화기 또는 대기오염방지시설에 관한 것이다.
In order to remove harmful gases generated in the home, various industrial sites, and offices of a building, the present invention uses a composite metal oxide low-temperature catalyst, which is not a conventional adsorption method, to remove harmful gas from harmful gases such as carbon dioxide, water and nitrogen An air purifier for completely decomposing and removing air, or an air pollution prevention facility.

종래의 실내 및 산업현장에서의 유해가스 제거 방법으로는 공기정화 장치를 사용하여 제거하였는데, 보다 상세하게는 분자간 흡인력을 이용하여 흡착 제거하는 활성탄, 실리카겔, 제올라이트, 이온교환수지 등의 흡착제를 일정 형태로 성형하여 공기 유동로의 중간에 충전하여 유해가스를 흡착 제거하거나 상기 흡착제를 부직포, 세라믹과 등과 같은 담체에 도포, 코팅하여 공기 유동로 상에 설치하여 흡착 제거하는 물리적 제거방법을 제공하였다. 이러한 활성탄 또는 제올라이트 등과 흡착제를 이용한 물리적 제거방법은 흡착량이 정해져 있으므로 일정 시간이 경과 함에 따라 흡착제거능력이 떨어지며, 일정 주기별로 교환을 해 주어야 하는 번거러움이 발생할 뿐만 아니라 상온 이상의 고온에서는 흡착 정화능력이 떨어진다는 단점이 있다. 또 주거 공간에서 바깥기온 등으로 인하여 온도가 상승시 흡착매체의 흡착능이 떨어져 공기 정화기에 흡착되어 있던 유해 기체가 오히려 주거 공간으로 역 방출되는 문제도 있다.Conventionally, harmful gas removal methods in indoor and industrial sites have been eliminated by using an air purification apparatus. More specifically, adsorbents such as activated carbon, silica gel, zeolite, ion exchange resin, etc., And the adsorbent is applied to a carrier such as a nonwoven fabric, a ceramic or the like, coated on the air flow path, and adsorbed and removed therefrom. The physical removal method using the adsorbent and the activated charcoal or zeolite by the adsorbent has the adsorption amount determined. Therefore, the adsorption removal ability decreases with a lapse of a predetermined time, and it is troublesome to exchange the adsorbent at a fixed period, There is a disadvantage. In addition, when the temperature rises due to the outside temperature in the residential space, the adsorption ability of the adsorption medium deteriorates, and the harmful gas adsorbed in the air purifier is discharged to the residential space rather.

또한 상기 기술은 비교적 저농도에서만 일시적인 제거효율을 발휘할 뿐 고농도에서의 적용은 경제적이지 않다.In addition, the above technology exhibits temporary removal efficiency only at a relatively low concentration, but is not economical to apply at a high concentration.

촉매를 이용한 유해가스 제거 방법으로 사용되는 상용화된 촉매가 백금(Pt), 티타늄(Ti) 등 귀금속 계통의 촉매들이며, 300~400℃에서 반응시켜 분해 제거하고 있다. 이러한 귀금속류의 촉매들은 가격이 고가이며, 300℃ 이하에서는 촉매의 성능이 발휘되지 않기 때문에 경제성이 떨어질 뿐더러 일반 가전제품이나 소규모의 처리풍량에 적용한 사례가 없다. 이 외에 광 촉매를 사용하여 유해가스를 제거하는 방법이 제공되고 있는데 대표적으로 사용되는 광촉매는 이산화티탄(TiO2)인데 이는 자외선을 흡수하여 일련의 과정을 거처 OH 라디칼과 활성산소를 만들어 이를 이용하여 간단한 유기물질을 절단하여 분해시켜 공기를 정화하는 기술이다. 따라서 광촉매를 활성화시켜 광화학반응을 일으키기 위해서는 별도의 자외선 발생장치와 이를 제어하는 장치가 필요하며, 이때 발생되는 자외선은 피부암 등을 일으키며, 눈을 실명시키는 등 치명적인 손상을 주는 문제점들이 있다.Commercially available catalysts used for removing harmful gases using catalysts are noble metal catalysts such as platinum (Pt) and titanium (Ti). They are decomposed and removed by reacting at 300 to 400 ° C. The catalysts of these precious metals are expensive, and the performance of the catalyst is not exhibited at temperatures below 300 ° C., which is not economical and is not applied to general household appliances or small-scale processed air volumes. In addition, there is a method of removing harmful gas by using a photocatalyst. The typical photocatalyst used is titanium dioxide (TiO 2 ), which absorbs ultraviolet rays to generate OH radicals and active oxygen through a series of processes, It is a technology to cleanse and decompose a simple organic material to purify the air. Therefore, a separate ultraviolet ray generating device and a device for controlling the ultraviolet ray generating device are needed in order to activate the photocatalyst by activating the photocatalyst. The ultraviolet ray generated in this case causes skin cancer and the like, and causes fatal damage such as blinding the eyes.

당사는 삼성전자주식회사와 공동으로 복합금속산화물 저온 촉매 필터를 이용하여 100℃ 이하의 온도에서 가정용 또는 사무실내 악취 및 휘발성유기화합물을 제거하는 방법을 출원하였다(공개특허 10-2012-0085079호). 이 경우 휘발성유기화합물의 경우 수십ppm 이내의 저농도일 경우 제거효율이 뛰어나나 고농도의 휘발성유기화합물이 발생하는 산업현장과 고풍량의 유해가스를 처리하고자하는 곳에 적용하기에는 한계가 있기에 본 발명에서는 도 1에 제시한 복합금속산화물 저온촉매가 내장된 장치를 이용하여 이러한 한계를 극복하고자 하였다.
We have applied for a method of removing odor and volatile organic compounds in domestic or office at temperatures below 100 ℃ by using a composite metal oxide low temperature catalyst filter in cooperation with Samsung Electronics Co., Ltd. (Japanese Patent Laid-Open No. 10-0085079). In this case, in the case of the volatile organic compound, the removal efficiency is excellent when the concentration is low within a few tens of ppm. However, since there is a limit to apply to industrial sites where high concentration of volatile organic compounds are generated and where high- Temperature catalysts of the composite metal oxides proposed in this paper.

본 발명은 신규 주택 입주 시 피부 호흡기 질환을 유발하는 포름알데하이드, 아세트산 등과 같은 새집증후군 유발 물질 즉, 보다 광범위하게는 휘발성 유기화합물 제거와 사무실 및 산업현장에서 발생되는 유해가스를 활성탄 흡착으로 제거하는 방법과 유/무기 화합물을 이용한 흡착 탈취를 이용한 화학적 흡착으로 제거하는 방법 그리고 향료를 이용한 마스킹(masking) 방법 등 종래의 기술을 사용하지 않고 복합금속산화물 저온촉매를 사용하여 유해가스를 완전히 분해 제거하고자 한다. 유해가스를 연소에 의해 완전히 분해 제거하기 위해서는 800℃ 이상의 열이 필요하나 본 기술에서 적용한 복합금속산화물 저온촉매를 사용 시 150℃ 이하에서도 분해 제거가 가능하며, 또한 실내에서 사용 시 배출온도가 고온인 경우 실용성이 없기 때문에 열회수율이 70% 이상 되는 열교환기를 장착하여 배기온도를 40℃ 이하로 낮춤으로 문제를 해결할 수 있었다. 본 기술을 적용한 제품은 100℃ 근방에서도 공기에 포함된 저농도의 유해가스 즉 휘발성 유기화합물, 암모니아(NH3) 및 악취 등의 제거가 가능하며 일산화탄소(CO), 오존(O3), 포름알데하이드 등과 같은 물질은 100℃ 이하에서도 제거가 가능하여 실내 공기질을 청정하게 유지시킬 수 있는 공기정화기이다. 본 기술은 150℃ 이하의 저온에서도 활성이 뛰어난 복합금속산화물 저온촉매, 바람직하게는 망간계 금속산화물 저온촉매 등의 개발 및 compact한 크기의 고효율의 열교환기 개발로 가능하게 되었다. 그러나 본 발명은 망간계 금속산화물 저온촉매만을 한정하는 것은 아니다.
The present invention relates to a method for removing sick sick syndrome such as formaldehyde and acetic acid which cause skin respiratory disease in a new home, that is, more broadly, removal of volatile organic compounds and toxic gases generated in offices and industrial sites by adsorption of activated carbon A method of removing by chemical adsorption using an adsorption / deodorization method using an organic / inorganic compound, and a masking method using a perfume, and to completely decompose and remove noxious gas using a composite metal oxide low temperature catalyst without using a conventional technique . In order to completely decompose and remove harmful gas by combustion, heat of 800 ° C or more is required. However, when using the composite metal oxide low temperature catalyst applied in this technology, it can be decomposed and removed even at 150 ° C or lower. It is possible to solve the problem by lowering the exhaust temperature to 40 캜 or less by installing a heat exchanger having a heat recovery rate of 70% or more. The product to which this technology is applied is capable of removing harmful gases such as volatile organic compounds, ammonia (NH 3 ) and odor contained in the air even in the vicinity of 100 ° C. It can also remove carbon monoxide (CO), ozone (O 3 ), formaldehyde The same material is an air purifier that can be removed even at 100 ° C or less to keep indoor air quality clean. The present technology has made it possible to develop a composite metal oxide low-temperature catalyst having excellent activity even at a low temperature of 150 ° C or lower, preferably a manganese-based metal oxide low-temperature catalyst, and to develop a compact high-efficiency heat exchanger. However, the present invention is not limited to the manganese-based metal oxide low-temperature catalyst.

본 발명에서 유해가스를 제거하기 위해 사용된 공기정화기술은 촉매연소방식이다. 이미 알려진 바와 같이 유해가스를 연소시켜 제거하기 위해서는 750~800℃의 고온에서 연소하여 완전히 제거시킨다. 따라서 에너지 비용의 저감 및 공정개선을 위해 이보다 낮은 온도에서 유해가스를 제거하기 위해 많은 연구를 통해 촉매를 개발하여 촉매 산화방식(Catalytic Oxidation: CO방식)에 의해 유해가스를 제거하는 방법을 개발하였다. 이때 사용되는 상용화된 촉매가 백금(Pt), 티타늄(Ti) 등 귀금속 계통의 촉매들이며, 300~400℃에서 반응시켜 분해 제거하고 있다. 이러한 귀금속류의 촉매들은 가격이 고가이며, 300℃ 이하에서는 촉매의 성능이 발휘되지 않기 때문에 경제성이 떨어질 뿐더러 일반 가전제품이나 산업용 제품에 적용하기가 쉽지 않다. 따라서 본 발명에서는 150℃ 이하에서도 제거효율이 우수한 복합금속산화물 저온촉매를 사용하여 일반 가정용 공기정화기 및 산업용 공기정화기로 적용하여 유해가스를 제거하고자 한다. 여기서 적용하는 촉매는 망간계 촉매로서 경제적이고 친환경적으로 유해가스를 제거할 수 있으며 촉매 가격이 저렴하고 운전 및 경제성이 우수한 장점이 있다. 또한 산업용 공기정화기의 경우 대기오염방지 시설 형태로도 사용이 가능하다.
In the present invention, the air purification technique used to remove harmful gas is a catalytic combustion method. As is already known, in order to burn and remove noxious gas, it is completely removed by burning at a high temperature of 750 to 800 ° C. Therefore, in order to reduce the energy cost and improve the process, many studies have been carried out to remove the harmful gas at a lower temperature and a method of removing the harmful gas by the catalytic oxidation (CO system) has been developed. The commercialized catalyst used here is a noble metal catalyst such as platinum (Pt) or titanium (Ti), and is decomposed and removed by reacting at 300 to 400 ° C. The catalysts of these precious metals are expensive, and the performance of the catalyst is not exhibited at temperatures below 300 ° C., which is not economical and is difficult to apply to general household appliances or industrial products. Therefore, in the present invention, it is desired to apply harmful gas to general household air purifiers and industrial air purifiers by using a composite metal oxide low temperature catalyst having a high removal efficiency even at 150 ° C or lower. The catalyst used here is a manganese-based catalyst, which is economical and eco-friendly and can remove harmful gas, has a low catalyst price, and is excellent in operation and economical efficiency. Industrial air purifiers can also be used as air pollution prevention facilities.
