본 발명은 각종 연소기의 배기가스 정화용 촉매에 관한 것으로, 특히 탈취촉매성분(활성성분)에 마이크로파를 흡수하여 발열하는 페라이트 성분을 혼합함으로서 조리중 마이크로파에 의해 촉매부 온도를 상승시켜 냄새를 효과적으로 제거하는데 적합한 촉매에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to catalysts for purifying exhaust gases of various combustors. In particular, by mixing ferrite components that absorb microwaves and generate heat by deodorizing catalyst components (active components), the temperature of the catalyst is increased by microwaves during cooking to effectively remove odors. It relates to a suitable catalyst.
일반적으로 전자레인지는 제1도와 같이 음식물을 조리하는 공간을 갖는 캐비티부(1)에는 내부를 밝혀주는 램프(2)와 조리열원인 히터(3)를 구비하고, 음식물의 종류에 따라 히터(3)의 동작시간과 출력을 자동적으로 조정해주는 마이콤부(4)와, 캐비티(1)를 개폐하는 도어(5)와, 이 도어의 개폐를 제어해주는 도어개폐버튼(6)과, 공기를 배기해주는 배기구(7)등으로 구성되며, 제2도와 같이, 전방부에 설치된 냉각핀(8)에 의해 흡입된 공기는 흡입구(9)를 통해 캐비티 내부로 흡입되어 공기의 유동흐름(Air flow)을 형성하게 되므로 조리시 발생되는 수증기 및 냄새는 배기구의 걸림쇠에 설치된 탈취촉매(10)를 경유하여 정화되면서 배기된다.In general, the microwave oven includes a lamp 2 illuminating the inside and a heater 3 serving as a cooking heat source in the cavity 1 having a space for cooking food as shown in FIG. 1, and the heater 3 according to the type of food. The microcomputer 4 automatically adjusts the operation time and output of the door, the door 5 for opening and closing the cavity 1, the door opening and closing button 6 for controlling the opening and closing of the door, and exhausting the air. It consists of an exhaust port (7), as shown in Figure 2, the air sucked by the cooling fin (8) provided in the front portion is sucked into the cavity through the inlet port 9 to form an air flow (Air flow) Therefore, the steam and smell generated during cooking are exhausted while being purified via the deodorizing catalyst 10 installed in the latch of the exhaust port.
제3도는 배기구에 장착된 탈취촉매를 나타낸 것이다.3 shows a deodorization catalyst mounted on the exhaust port.
(a)는 전체상태도이고, (b)는 (a)의 일점쇄선을 확대한 종래의 탈취촉매의 구성도로서, 세라믹 담체위에 선택한 활성성분인 귀금속(Pd, Pt)을 Υ-Al2O3재질로 된 워쉬코트(wash coat)층에 담지시킨 형태로 이루어진다. 이런 촉매를 전자레인지에 부착하여 사용하면 유해 및 냄새 성분은 아래와 같이 공기중 O2와 반응하여 산화분해된다(제4도).(a) is a full state diagram, (b) is a schematic view of (a) conventional deodorizing catalyst an expanded view of a one-dot-dash line in, the noble metal (Pd, Pt) an active ingredient selected on a ceramic carrier Υ-Al 2 O 3 It is made of a form supported on a wash coat layer of the material. When such a catalyst is attached and used in a microwave oven, harmful and odorous components are oxidatively decomposed by reacting with O 2 in air as shown below (Fig. 4).
그러나 조리중 배기구에 설치된 촉매부온도가 저온(50℃이하)이므로 효율적인 탈취 및 가스정화율을 기대하기 어렵다.However, it is difficult to expect efficient deodorization and gas purification rate because the catalyst portion temperature installed in the exhaust port during cooking is low temperature (less than 50 ℃).
본 발명은 상기한 종래의 문제점을 해결하기 위해 안출한 것으로, 세라믹 담체에 코팅하는 워쉬코트층 내부에 담지하는 귀금속 촉매성분에 마이크로파를 흡수하여 발열하는 페라이트 성분을 일정비율 혼합하여 담지함으로써 촉매부 온도를 상승시켜 탈취반응을 활성화할 수 있는 촉매를 얻고자 하는데 그 목적이 있다.The present invention has been made to solve the above-described problems, the catalyst part temperature by mixing a certain ratio of the ferrite component that absorbs microwaves and generates heat in the noble metal catalyst component supported on the washcoat layer coated on the ceramic carrier. The purpose is to obtain a catalyst that can activate the deodorization reaction by raising the.
이하 본발명을 설명한다.The present invention will be described below.
본 발명은 세라믹 담체위에 코팅되는 워쉬코트(wash coat)층 내부에 담지하는 귀금속 촉매에 있어서 상기 귀금속 촉매에 마이크로파를 흡수하여 발열하는 페라이트 성분이 혼합된 촉매로 이루어진다.The present invention consists of a catalyst in which a ferrite component is mixed with the noble metal catalyst to generate heat by absorbing microwaves in the noble metal catalyst supported on a wash coat layer coated on a ceramic carrier.
제3도의 (c)는 상기한 본 발명을 나타낸 것으로, 귀금속(Pt, Pd, ……), 금속 산화물(CuO, Fe2O3, ……)에 마이크로파를 흡수하여 발열하는 페라이트 성분(Ba, Sr 중 선택 또는 혼합)을 홉합하고, 기존의 워쉬코트 성분인 Υ-Al2O3와 믹싱하여 세라믹 담체위에 코팅한다.(C) of FIG. 3 shows the present invention as described above. The ferrite component Ba, which absorbs microwaves and generates heat to the noble metals (Pt, Pd, ...), and the metal oxides (CuO, Fe 2 O 3 , ...) Select or mix in Sr), mix with the existing washcoat component Υ-Al 2 O 3 and coat on a ceramic carrier.
이때 촉매 성분과 페라이트 성분의 구성비율은 중량%로서 0.5-5% : 95-99.5%로 함이 바람직하다.At this time, the composition ratio of the catalyst component and the ferrite component is preferably 0.5-5%: 95-99.5% by weight.
이와같이 페라이트 성분이 포함된 촉매는 페라이트성분이 마이크로파를 흡수하여 저온상태를 갖는 촉매부의 온도를 200℃까지 높여준다.Thus, the catalyst containing the ferrite component increases the temperature of the catalyst portion having a low temperature state by the ferrite component absorbs microwaves to 200 ℃.
따라서 제5도와 같이 촉매체의 온도상승에 따라 촉매성분(촬성성분)이 활성화 되어 발생되는 조리냄새에 대한 효과적인 탈취가 이루어진다.Therefore, as shown in FIG. 5, the effective deodorization of the cooking odor generated by the activation of the catalyst component (photographing component) is performed according to the temperature rise of the catalyst body.
제6도는 본 발명에 따른 가스정화의 실험결과를 나타낸 것이다.6 shows the experimental results of gas purification according to the present invention.
이때 시험조건은 SV = 20,000(h-1), iSO - C4H8농도 = 1000 ± 100ppm으로 하여 종래와 본 발명을 비교한 결과, 마이크로파를 흡수발열하는 페라이트로 인해 상승되는 온도 200℃ 기준하여 본발명의 정화율은 약 78%로서 매우 우수하였다.At this time, the test conditions were SV = 20,000 (h -1 ), iSO-C 4 H 8 concentration = 1000 ± 100ppm compared with the prior art and the present invention, based on the temperature rising 200 ℃ due to the ferrite absorbing microwaves The purification rate of the present invention was about 78%, which was very good.
이상에서와 같이, 본 발명은 기존의 탈취촉매에 마이크로파를 흡수하여 발열하는 페라이트를 첨가함으로써, 저온상태를 이루는 촉매부의 온도를 상승시켜 효율적인 가스정화효과를 갖는 탈취 촉매를 얻게 된다.As described above, according to the present invention, by adding a ferrite that absorbs microwaves and generates heat to an existing deodorizing catalyst, the deodorizing catalyst having an effective gas purification effect can be obtained by raising the temperature of the catalytic part forming a low temperature state.
