이하에서는 상기와 같은 본 발명의 중공형 흡착/촉매셀 및 그 제조방법의 기술적 사상에 따른 바람직한 실시 예를 첨부도면을 참조하여 설명하면 다음과 같다. Hereinafter, with reference to the accompanying drawings, a preferred embodiment according to the technical spirit of the hollow-type adsorption / catalyst cell of the present invention and the manufacturing method as described above are as follows.

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 with reference to FIG. 1 as follows.

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 manufactured.

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.The spherical precursor 11 mixed with a plurality of catalyst materials 13 and the first carbon component 12 becomes an inner wick portion of the adsorption / catalyst cell 10 of the present invention, and the material of the first carbon component 12 Is made of a material with 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 can be easily thermally decomposed at a low temperature, and preferably an acrylic resin, butyral resin, or αmethyl styrene having a residual carbon content of 5% or less when heated to 600 ° C. under inert gas ( methyl styrene).

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 catalytic material 13, a single component or a mixture of transition metals such as zinc (Zn), iron (Fe), cobalt (Co), nickel (Ni) and copper (Cu) and / or precious metals such as platinum, palladium and rhodium It can be introduced as a 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.In addition, the catalyst material 13 may be excited when light energy is irradiated to obtain deodorization, antibacterial action, and the like, and may use metal oxides such as titanium oxide, tin oxide, and zinc oxide, which cause decomposition reactions based on redox reactions. 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 catalyst materials 13 are mixed to form a circular shape through firing or the like.

제 2공정으로, 다수의 촉매물질(13)이 혼합된 구형 탄소전구체(11)의 표면 외부에 제2탄소성분을 코팅하여 제1흡착층(14)을 형성한다.In the second process, the second adsorption layer 14 is formed by coating a second carbon component on the outside of the surface of the spherical carbon precursor 11 in which the plurality of catalyst materials 13 are mixed.

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 component material having a higher carbonization point than the first carbon component 12. The second carbon component may be a phenol resin, aromatic carbonate resin, coal tar, etc., in which residual carbon content is 60% or more when heated to 600 ° C. under inert gas. In addition, carbohydrates such as sucrose, glucose and xylose may be used as the carbon raw material.

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, the first adsorption layer 14 is formed by coating one of the second carbon component materials on the outside of the surface of the spherical carbon precursor 11 including the plurality of catalyst materials 13 using a dipping method or the like. The thickness of the first adsorption layer 14 may be variously adjusted to about 10 to 1000 nm.

제 3공정으로, 제 2공정을 통하여 얻어진 구조체의 제1흡착층(14) 표면 외부에 무기 산화물을 코팅하여 제2흡착층(15)을 형성한다.In a third process, an inorganic oxide is coated on the outside of the surface of the first adsorption layer 14 of the structure obtained through the second process to form the second adsorption layer 15.

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 adsorption layer 15, inorganic oxides such as silica (SiO 2 ) or aluminum oxide having excellent hydrophilicity, light permeability, excellent light resistance and weather resistance to light energy, and the like are used. SiO 2 ) is used. The thickness of the second adsorption layer 15 may preferably be adjusted to about 0.1 to 0.8 μm.

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.Silica (SiO 2 ) coated on the 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 catalytic material 13. It plays a role. That is, when light energy is irradiated to the catalyst material 13, the catalyst material 13 performs active photocatalytic reaction to decompose malodorous gas formed of organic matter or nitrogen oxide and maintains high hydrophilicity. The second adsorption layer 15 made of silica (SiO 2 ) maintains the hydrophilicity obtained through the photocatalytic action.

제 4공정으로, 제 3공정을 통하여 얻어진 구조체를 열처리하여 제1탄소성분(12)을 모두 제거한다.In a fourth step, the structure obtained through the third step is heat treated to remove all of the first carbon component 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 result obtained by coating the first adsorption layer 14 and the second adsorption layer 15 on the structure obtained through the third process, that is, the surface of the spherical carbon precursor 11 mixed with a plurality of catalyst materials 13 The heat treatment at 600 ℃ to 900 ℃ under an inert gas to induce a carbonization process. In this case, the first carbon component 12 having the lower carbonization point among the spherical precursors 11 mixed with the first carbon component 12 and the catalyst material 13 corresponding to the inner wick portion of the finished result is 600 ° C. In the case of heating up to the above, the carbonation reaction converts carbon dioxide into carbon dioxide with little residual carbon content remaining.

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.In addition, 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, residual carbon is left and the first adsorption layer is porous. (14) is formed.

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.Therefore, as the first carbon component 12 constituting the inner wick portion of the structure obtained through the third process is carbonized through heat treatment and completely removed, the inner wick portion is formed with a spherical hollow portion 16 and the hollow portion ( 16, only a plurality of catalyst materials 13 remain in a suspended 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, in the process of discharging carbon dioxide (CO 2 ) generated in the process of carbonizing the first and second carbon components 12 and 14 to the outside through the second adsorption layer 15, the second adsorption layer 15 may be fine.

이하에서는 본 발명의 제조방법에 의하여 제조된 중공형 흡착/촉매셀의 작용 및 효과에 대하여 살펴본다.Hereinafter, the action and effects of the hollow adsorption / catalyst cell prepared by the production 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 to the second adsorption layer 15 formed of silica (SiO 2 ) of the hollow adsorption / catalyst cell 10 of the present invention are second The material transfer through the micropores of the adsorption layer 15 is moved to the first adsorption layer 14 of the carbon component material. The pollutant adsorbed on the first adsorption layer 14 is transferred to the hollow portion 16, which is an inner wick portion in which a plurality of catalyst materials 13 are suspended, through the adsorption layer destruction, and is oxidized by the catalyst material 13. Decompose

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.In addition, when light energy such as UV lamp or plasma is irradiated to the hollow adsorption / catalyst cell 10, the light energy penetrates through the second adsorption layer 15 made of silica (SiO 2 ) and the hollow part, which is an inner wick part. Activate the catalyst material 13 provided in (16). Since the movement is accelerated by the repulsive force and the collision in the hollow portion 16 between the activated catalyst material 13, the decomposition efficiency of the pollutant also increases.

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.In addition, hydrophilicity (H 2 O) generated as the contaminants are decomposed by the catalyst material 13 is maintained by the second adsorption layer 15 made of silica (SiO 2 ), and the hydrophilicity (H 2 O) is Since active radicals (OH − ) are generated by light energy such as plasma, pollutants and the like are more efficiently decomposed by these active radicals.
