이하에서는 상기와 같은 본 발명의 중공형 흡착/촉매셀 및 그 제조방법의 기술적 사상에 따른 바람직한 실시 예를 첨부도면을 참조하여 설명하면 다음과 같다. Hereinafter, preferred embodiments of the hollow adsorption / catalyst cell of the present invention and the manufacturing method thereof will be described with reference to the accompanying drawings.

먼저 도 1을 참조하여 본 발명의 중공형 흡착/촉매셀의 제조과정을 단계별로 설명하면 다음과 같다.First, the manufacturing process of the hollow adsorption / catalyst cell of the present invention will be described step by step with reference to FIG.

제 1공정으로, 제1탄소성분(12)과 촉매물질(13)이 혼합된 구형 전구체(11)를 제조한다.In the first step, a spherical precursor 11 in which the first carbon component 12 and the catalyst material 13 are mixed is prepared.

다수의 촉매물질(13)과 제1탄소성분(12)이 혼합된 구형 전구체(11)는 본 발명의 흡착/촉매셀(10)의 내부 심지 부분이 되는 것으로서 제1탄소성분(12)의 물질은 낮은 탄화점을 가지는 물질로 이루어 진다.A spherical precursor 11 in which a plurality of catalytic materials 13 and a first carbon component 12 are mixed is an inner wicking portion of the adsorption / Is made of a substance having a low carbonization point.

이러한 제1탄소성분(12)은 낮은 온도에서 용이하게 열분해 가능한 수지를 사용하며 바람직하게는 비활성 기체하에서 600℃까지 가열하는 경우 잔류 탄소분이 5% 이하인 아크릴 수지나, 부티랄 수지, α메틸 스틸렌(methyl styrene)등을 사용 할 수 있다.The first carbon component 12 is a resin which is easily pyrolyzable at a low temperature and preferably is an acrylic resin having a residual carbon content of 5% or less when heated up to 600 ° C. under an inert gas, a butyral resin, a methylstyrene methyl styrene) and the like can be used.

촉매물질(13)로는 아연(Zn), 철(Fe), 코발트(Co), 니켈(Ni), 구리(Cu)등의 전이금속 및/또는 백금, 팔라듐, 로듐 등의 귀금속이 단일성분 또는 혼합성분으로 도입 가능하며 촉매 효율에 따라서 적절한 함량을 갖도록 마련된다.As the catalyst material 13, a transition metal such as zinc (Zn), iron (Fe), cobalt (Co), nickel (Ni) or copper (Cu) and / or a noble metal such as platinum, Component and is prepared to have an appropriate content according to the catalyst efficiency.

또한 촉매물질(13)은 탈취, 항균 작용등을 얻을 수 있도록 광에너지가 조사되면 광여기되고, 산화 환원반응에 기초한 분해 반응을 야기하는 산화티탄, 산화주석 및 산화아연등의 금속 산화물을 사용할 수 있다.Further, the catalytic substance 13 may be a metal oxide such as titanium oxide, tin oxide and zinc oxide, which is photo-excited when light energy is irradiated so as to obtain deodorization, antibacterial action, etc. and causes a decomposition reaction based on the oxidation- have.

따라서, 제1탄소성분(12)과 다수의 촉매물질(13)을 혼합한 후 소성등을 통하여 원형 형상으로 만든다.Therefore, the first carbon component 12 and the plurality of catalytic materials 13 are mixed and fired to form a circular shape.

제 2공정으로, 다수의 촉매물질(13)이 혼합된 구형 탄소전구체(11)의 표면 외부에 제2탄소성분을 코팅하여 제1흡착층(14)을 형성한다.In the second step, the second carbon component is coated on the outer surface of the spherical carbon precursor 11 mixed with the plurality of catalytic materials 13 to form the first adsorption layer 14.

제1흡착층(14)은 제1탄소성분(12)에 비하여 상대적으로 높은 탄화점을 가지는 제2탄소성분 물질로 이루어진다. 이러한 제2탄소성분 물질은 비활성 기체하에서 600℃까지 가열하는 경우 잔류 탄소분이 60%이상 잔류하는 페놀수지, 방향족 카보네이트수지, 콜타르 등이 사용될 수 있다. 또한, 수크로오스(sucrose), 글루코오스(glucose), 자일로오스(xylose) 등의 탄수화물을 탄소 원료로 사용할 수 있다.The first adsorption layer 14 is made of a second carbon-based material having a relatively higher carbonization point than the first carbon component 12. Such a second carbon component material may be a phenol resin, an aromatic carbonate resin, a coal tar, or the like, in which residual carbon content is 60% or more when heated to 600 ° C under an inert gas. In addition, carbohydrates such as sucrose, glucose and xylose can be used as carbon sources.

즉, 다수의 촉매물질(13)이 포함된 구형 탄소전구체(11)의 표면 외부에 디핑법등을 이용하여 제2탄소성분 물질 중 하나를 코팅하여 제1흡착층(14)을 형성한다. 이러한 제1흡착층(14)의 두께는 바람직하게 10 내지 1000nm 정도로 다양하게 조절 할 수 있다.That is, one of the second carbon component materials is coated on the outer surface of the spherical carbon precursor 11 containing a plurality of catalytic materials 13 using a dipping method to form the first adsorption layer 14. The thickness of the first adsorptive layer 14 can be variously adjusted to preferably about 10 to 1000 nm.

제 3공정으로, 제 2공정을 통하여 얻어진 구조체의 제1흡착층(14) 표면 외부에 무기 산화물을 코팅하여 제2흡착층(15)을 형성한다.In the third step, the second adsorption layer 15 is formed by coating the outer surface of the first adsorption layer 14 of the structure obtained through the second step with an inorganic oxide.

제2흡착층(15)의 재료로는 친수성이 우수하고, 빛의 투과성이 있으며 광에너지등에 대한 내광성 및 내후성이 우수한 실리카(SiO2) 또는 산화알루미늄등의 무기 산화물을 사용하며 바람직하게는 실리카(SiO2)를 사용한다. 제2흡착층(15)의 두께는 바람직하게 0.1 내지 0.8μm 정도로 조절할 수 있다.As the material of the second adsorptive layer 15, an inorganic oxide such as silica (SiO 2 ) or aluminum oxide which is excellent in hydrophilicity, permeable to light, excellent in light resistance and weather resistance against light energy, is used, SiO 2 ) is used. The thickness of the second adsorptive layer 15 can be adjusted preferably to about 0.1 to 0.8 mu m.

이러한 제1흡착층(14) 표면 외부에 코팅되는 실리카(SiO2)는 구형 탄소전구체(11)의 제1흡착층(14) 표면을 보호하고, 또한 촉매물질(13)에 의해 얻어진 친수성을 유지하는 역할을 한다. 즉, 촉매물질(13)에 광에너지가 조사되는 경우 촉매물질(13)은 활발한 광촉매 반응을 하여 유기물이나 질소 산화물로 형성된 악취가스를 분해하여 높은 친수성을 유지하며, 광에너지가 조사되자 않는 경우에는 실리카(SiO2) 재질의 제2흡착층(15)에 의해 광촉매 작용을 통하여 얻어진 친수성을 유지하게 된다.The silica (SiO 2 ) coated on the outer surface of the first adsorption layer 14 protects the surface of the first adsorption layer 14 of the spherical carbon precursor 11 and maintains the hydrophilicity obtained by the catalyst material 13 . That is, when the catalytic material 13 is irradiated with light energy, the catalytic material 13 performs an active photocatalytic reaction to decompose the odorous gas formed of organic materials or nitrogen oxides to maintain high hydrophilicity. When the optical energy is not irradiated And the hydrophilic property obtained through the photocatalytic action is maintained by the second adsorption layer 15 made of silica (SiO 2 ).

제 4공정으로, 제 3공정을 통하여 얻어진 구조체를 열처리하여 제1탄소성분(12)을 모두 제거한다.In the fourth step, the structure obtained through the third step is subjected to heat treatment to remove all the first carbon components (12).

제3공정을 통하여 얻어진 구조체 즉, 다수의 촉매물질(13)이 혼합된 구형 탄 소전구체(11)의 표면에 제1흡착층(14)과 제2흡착층(15)을 코팅하여 완성된 결과물을 비활성기체하에서 600℃ 내지 900℃의 온도에서 열처리하여 탄소화 과정을 유도한다. 이 경우 완성된 결과물의 내부 심지 부분에 해당되는 제1탄소성분(12)과 촉매물질(13)이 혼합된 구형 전구체(11) 중 낮은 탄화점을 가지고 있는 제1탄소성분(12)은 600℃ 이상 까지 가열하는 경우 탄소화 반응에 의해 잔류 탄소분이 거의 남지 않고 이산화탄소로 전환된다.The first adsorption layer 14 and the second adsorption layer 15 are coated on the surface of the spherical carbon precursor 11 in which the structure obtained through the third step, that is, the plurality of catalyst materials 13 is mixed, Is subjected to a heat treatment under an inert gas at a temperature of 600 ° C to 900 ° C to induce a carbonization process. In this case, the first carbon component 12 having a low carbonization point among the spherical precursor 11 mixed with the first carbon component 12 and the catalyst material 13 corresponding to the inner wick portion of the finished product, Or more, the remaining carbon content is almost completely left by the carbonization reaction and is converted into carbon dioxide.

또 제1흡착층(14)을 형성하는 제2탄소성분(14)은 제1탄소성분(12)의 탄화점에 비하여 상대적으로 높은 탄화점을 가지므로 잔류 탄소분이 남게 되어 다공성의 제1흡착층(14)을 형성하게 된다.Also, since the second carbon component 14 forming the first adsorption layer 14 has a relatively higher carbonization point than the carbonization point of the first carbon component 12, the residual carbon fraction remains, (14).

따라서, 제 3공정을 통하여 얻어진 구조체의 내부 심지부분을 이루는 제1탄소성분(12)은 열처리를 통하여 탄화되어 완전히 제거됨에 따라 내부 심지부분은 구형의 중공부(16)가 형성되고 이러한 중공부(16)에는 다수의 촉매물질(13)만이 부유상태로 남게 된다.Accordingly, the first carbon component 12 forming the inner wick portion of the structure obtained through the third step is completely removed by the carbonization through the heat treatment, so that the inner wick portion is formed into the spherical hollow portion 16, 16, only a large number of catalyst materials 13 remain in a floating state.

또한, 제1,2탄소성분(12,14)이 탄화되는 과정에서 발생하는 이산화탄소(CO2)가 제2흡착층(15)을 통하여 외부로 배출되는 과정에서 제2흡착층(15)에는 미세기공이 형성되게 된다.In addition, the carbon dioxide (CO 2 ) generated during the carbonization of the first and second carbon components 12 and 14 is discharged to the outside through the second adsorption layer 15. In the second adsorption layer 15, Pores are formed.

이하에서는 본 발명의 제조방법에 의하여 제조된 중공형 흡착/촉매셀의 작용 및 효과에 대하여 살펴본다.Hereinafter, the operation and effect of the hollow adsorption / catalyst cell manufactured by the manufacturing method of the present invention will be described.

본 발명의 중공형 흡착/촉매셀(10)의 실리카(SiO2) 재질로 형성된 제2흡착층(15)에 흡착되는 C 및 H 등으로 구성된 휘발성 유기화합물(VOCs)등의 오염 물질들은 제2흡착층(15)의 미세기공을 통한 물질전달에 의하여 탄소성분 물질의 제1흡착층(14)으로 이동하게 된다. 제1흡착층(14)에 흡착된 오염물질은 흡착층 파괴등을 통해 다수의 촉매물질(13)이 부유하고 있는 내부 심지부분인 중공부(16)로 전달되어 촉매물질(13)에 의하여 산화 분해된다.Contaminants such as volatile organic compounds (VOCs) composed of C and H adsorbed on the second adsorption layer 15 formed of the silica (SiO 2 ) material of the hollow adsorption / catalyst cell 10 of the present invention, And is moved to the first adsorption layer 14 of the carbonaceous material by the mass transfer through the micropores of the adsorption layer 15. The contaminants adsorbed on the first adsorption layer 14 are transferred to the hollow portion 16 which is the inner wicking portion floating on the plurality of catalytic materials 13 through the destruction of the adsorption layer, Decomposed.

또 중공형 흡착/촉매셀(10)에 UV램프나 플라즈마 등의 광에너지가 조사되는 경우에는 광에너지는 실리카(SiO2) 재질의 제2흡착층(15)을 투과하여 내부 심지부분인 중공부(16)에 마련된 촉매물질(13)을 활성화 시키게 된다. 활성화된 촉매물질(13) 상호간에는 반발력 및 중공부(16) 내에서의 충돌에 따라 움직임이 가속화되게 되므로 오염물질의 분해 효율 또한 증가하게 된다.When light energy such as UV lamp or plasma is irradiated to the hollow adsorption / catalyst cell 10, the light energy is transmitted through the second adsorption layer 15 made of silica (SiO 2 ) Thereby activating the catalytic material 13 provided in the reaction chamber 16. Since the movement of the activated catalytic materials 13 is accelerated according to the repulsive force and the collision in the hollow part 16, the decomposition efficiency of the pollutant is also increased.

또 촉매물질(13)에 의하여 오염물질들이 분해됨에 따라 발생하는 친수성(H2O)은 실리카(SiO2) 재질의 제2흡착층(15)에 의해 유지되며, 이러한 친수성(H2O)은 플라즈마와 같은 광에너지에 의하여 활성 라디칼(OH-)이 생성되므로 이러한 활성 라디칼에 의하여 더욱더 효율적으로 오염물질등이 분해되게 된다.The hydrophilicity (H 2 O) generated by the decomposition of the contaminants by the catalyst material 13 is maintained by the second adsorption layer 15 made of silica (SiO 2 ), and the hydrophilicity (H 2 O) Since active radicals (OH - ) are generated by light energy such as plasma, contaminants and the like are more efficiently decomposed by these active radicals.

도 1은 본 발명에 따른 중공형 흡착/촉매셀의 제조 과정을 도시하여 나타낸 것이다.1 shows a process of manufacturing a hollow adsorption / catalyst cell according to the present invention.
