Description
본 발명은 냉장고, 전자렌지, 그릴, 오븐, 공기청정기 및 음식쓰레기 발효 처리장치 등에 적용되어 음식물, 쓰레기 등에서 발생하는 다양한 악취를 제거할 수 있는 탈취촉매, 그 제조방법 및 탈취장치에 관한 것이다.The present invention is applied to a refrigerator, a microwave oven, a grill, an oven, an air purifier and a food waste fermentation treatment apparatus, and the like, and a deodorization catalyst capable of removing various odors generated from food, garbage, and the like, and a method and a deodorization apparatus thereof.
산업 기술이 발전하면서 이에 따른 부산물로 수많은 오염물질들이 배출되고 대기, 수질 등 환경 오염이 날로 심각해지고 있다. 악취는 가정의 음식물이나 쓰레기, 사무실이나 공장, 공공시설, 폐수처리장, 축사 등에서 폭넓게 발생하고 있다. 악취 유발 물질로는 암모니아, 트리메틸아민, 트리에틸아민 등 질소 함유 화합물, 황화수소, 머캅탄 같은 황 화합물, 포름알데히드, 아세트알데히드 등의 알데히드, 포름산, 아세트산, 프로피온산, 발레르산 등의 저급 지방산 등이 대표적이다. As industrial technology develops, many pollutants are emitted as by-products, and environmental pollution such as air and water is getting worse day by day. Odors are widespread in household food and waste, offices and factories, public facilities, wastewater treatment plants, and barns. Odor-inducing substances include nitrogen-containing compounds such as ammonia, trimethylamine and triethylamine, sulfur compounds such as hydrogen sulfide and mercaptan, aldehydes such as formaldehyde and acetaldehyde, and lower fatty acids such as formic acid, acetic acid, propionic acid and valeric acid. to be.
종래 탈취 방법에는 예컨대 활성탄 등의 흡착재에 악취 가스를 흡착하는 흡착법, 물이나 산화제 등을 이용하여 중화 또는 산화 반응으로 악취 성분을 흡착 제거하는 세척법, 악취 성분을 연소에 의하여 열분해시키는 연소법, 악취 성분을 상온에서 산화 반응시키고 분해하는 오존법 등이 있다. Conventional deodorizing methods include, for example, an adsorption method of adsorbing malodorous gas to an adsorbent such as activated carbon, a washing method of adsorbing and removing malodorous components by neutralization or oxidation using water or an oxidizing agent, a combustion method of thermally decomposing malodorous components by combustion, and a malodorous component. And ozone method for oxidizing and decomposing at room temperature.
그러나, 활성탄은 흡착용량이 부족하다. 이 때문에 할로겐 화합물이나 금속 이온 등을 담지한 활성탄 흡착제가 제안되어 왔다. 그러나, 이와 같은 흡착제 또한 충분한 탈취 성능을 보이지 않는 문제점이 있었다. However, activated carbon lacks adsorption capacity. For this reason, activated carbon adsorbents carrying halogen compounds, metal ions and the like have been proposed. However, such an adsorbent also has a problem that does not show sufficient deodorizing performance.
최근에는 제올라이트, 알루미나 등의 다공성 물질에 백금, 구리 등 귀금속이나 금속 활성물질을 담지한 탈취 촉매가 개발되어 냉장고, 오븐, 그릴 등의 조리기구 등에 적용되고 있다. 그러나, 종래의 탈취 촉매 및 이를 이용한 기구들은 다양한 악취 가스성분에 대하여 충분한 탈취 기능을 발휘하지 못하는 문제점이 있었다. Recently, deodorization catalysts in which precious metals such as platinum and copper or metal active materials are supported on porous materials such as zeolite and alumina have been developed and applied to cooking appliances such as refrigerators, ovens, and grills. However, the conventional deodorizing catalyst and the apparatus using the same have a problem that it does not exhibit sufficient deodorizing function for various odor gas components.
따라서, 본 발명은 다양한 악취 성분에 대하여 충분한 탈취 기능을 나타내는 탈취 촉매 조성물을 제공하려는 것을 목적으로 한다.Accordingly, it is an object of the present invention to provide a deodorizing catalyst composition that exhibits sufficient deodorizing function for various malodorous components.
상기 목적을 달성하기 위하여 본 발명자들은 오랜 기간의 연구를 통하여 여러 가지 금속 활성물질 중 몇 가지 종류와 그 함량을 조절한 결과 알데히드류, 암모니아, 머캅탄, 황화수소 등의 황화합물, 아민류, 톨루엔 등의 다양한 악취가스 성분과 복합악취를 현저히 제거할 수 있는 탈취 촉매를 완성하기에 이르렀다.

상기 담지체는 탈취 효과를 높이기 위하여 넓은 표면적을 가지도록 형성되며, 무수한 기공을 가지도록 형성된다. 바람직하게는 상기 다수개의 기공은 담지체 전체에 균일하게 형성된다. The carrier is formed to have a large surface area in order to enhance the deodorizing effect, it is formed to have a myriad of pores. Preferably, the plurality of pores is uniformly formed throughout the support.

본 발명의 탈취촉매 제조방법은 담지체를 활성금속이 용해되어 있는 담지용액에 담지하는 것이다. 담지체는 알루미나, 코랄샌드, 제올라이트, 활성탄 및 실리 카 중 1종 이상으로 제조된 것을 사용할 수 있다. 담지체는 판 형상, 구 형상, 원기둥이나 각기둥 형상, 원판 형상, 육면체 형상 등으로 다양하게 형성할 수 있으며, 특별한 제한은 없다. 바람직하게는 탈취촉매가 적용되는 장치에 따라 다양한 모양으로 변형 가능하다. 또한, 상기 담지체는 표면적이 넓어야 하므로 다수개의 통공을 형성하는 것이 바람직하다. The deodorizing catalyst production method of the present invention is to carry a supporting body in a supporting solution in which an active metal is dissolved. The carrier may be one made of one or more of alumina, coral sand, zeolite, activated carbon and silica. The carrier may be variously formed in a plate shape, a sphere shape, a cylinder or a prismatic shape, a disc shape, a hexahedron shape, and the like, and there is no particular limitation. Preferably, the deodorizing catalyst may be modified into various shapes depending on the apparatus to which the deodorizing catalyst is applied. In addition, since the carrier should have a large surface area, it is preferable to form a plurality of through holes.
이와 같이 제조된 담지체는 백금, 금, 질산구리 수화물, 질산망간 수화물, 초산코발트를 포함하는 활성금속 담지용액에 담지하여 담지체 표면에 활성금속을 결합시킴으로써 탈취촉매를 제조하게 된다. The carrier thus prepared is supported on an active metal supporting solution containing platinum, gold, copper nitrate hydrate, manganese nitrate hydrate, and cobalt acetate to bond the active metal to the surface of the carrier to produce a deodorizing catalyst.
이 과정을 좀더 자세히 설명하면, 먼저 용액 중량당 백금 0.05~0.25중량%, 금 0.05~0.25중량%, 질산구리 수화물 10~35중량%, 질산망간 수화물 10~35중량%, 초산코발트 10~35중량%의 활성금속이 함유된 담지용액을 제조한다. 각 성분이 상기 함량 범위보다 낮은 경우 각 악취에 따라 제거율이 저하되며, 상한보다 높은 경우에는 효능은 향상되나 활성금속이 고가이므로 비경제적이다. 또, 상기 함량은 탈취촉매의 내구성과 관련이 있다. 자세히 설명하면, 활성금속 담지용액의 함량이 상기 함량 범위보다 낮은 경우에는 내구성(탈취능 지속능력)이 최대 30%까지 저하된다. To explain this process in more detail, first, 0.05 to 0.25% by weight of platinum, 0.05 to 0.25% by weight of gold, 10 to 35% by weight of copper nitrate hydrate, 10 to 35% by weight of manganese nitrate hydrate, and 10 to 35 weight of cobalt acetate Prepare a supporting solution containing% active metal. When each component is lower than the content range, the removal rate is lowered according to each odor, and when higher than the upper limit, the efficacy is improved, but the active metal is expensive, which is uneconomical. In addition, the content is related to the durability of the deodorizing catalyst. In detail, when the content of the active metal carrying solution is lower than the content range, the durability (deodorization sustainability) is reduced by up to 30%.
상기 담지용액에 담지체를 담지한 후 건조하고 소성하여 본 발명의 탈취촉매를 제조할 수 있다.After supporting the carrier in the supporting solution, it is dried and calcined to prepare the deodorizing catalyst of the present invention.
바람직하게는 담지체를 상기 활성금속이 함유된 담지용액에 50분~120분 동안 담지하여 담지용액의 활성금속이 담지체에 충분히 침투하도록 하는 1차 담지 단계;Preferably, the first supporting step for the carrier to support the active metal containing solution for 50 minutes to 120 minutes to sufficiently penetrate the active metal of the supporting solution into the carrier;
상기 1차 담지 단계를 거친 담지체를 건조로에서 건조하는 1차 건조 단계; A primary drying step of drying the carrier having undergone the primary supporting step in a drying furnace;
상기 1차 건조 단계를 거친 담지체를 활성금속이 함유된 담지용액에 50~120분 동안 2차 담지하는 단계;Secondary supporting the carrier having undergone the first drying step in a supporting solution containing an active metal for 50 to 120 minutes;
상기 2차 담지한 담지체를 건조하는 2차 건조 단계;A secondary drying step of drying the secondary supported carrier;

상기 1차 또는 2차 건조는 온도에 특별한 제한은 없으나, 80~90℃에서 건조하는 것이 바람직하다. 1차 건조는 3~4시간, 2차 건조는 8~10시간이 바람직하다. 상기 2차 건조 단계에서 담지체를 완전 건조시키지 않은 채로 소성하는 경우에는 탈취촉매의 수명과 성능이 단축되는 문제점이 발생한다. The primary or secondary drying is not particularly limited in temperature, it is preferable to dry at 80 ~ 90 ℃. The primary drying is preferably 3 to 4 hours, and the secondary drying is preferably 8 to 10 hours. When firing the carrier without completely drying in the secondary drying step, there is a problem that the life and performance of the deodorizing catalyst is shortened.
상기 소성 단계에서 250~500℃의 온도로 2~5시간 충분히 소성하지 않는 경우에는 제조된 탈취촉매에서 가스가 발생할 수 있다.If the baking step does not sufficiently bake at a temperature of 250 to 500 ° C. for 2 to 5 hours, gas may be generated in the prepared deodorizing catalyst.
