도 1은 본 발명의 일 실시예에 따른 자동차용 냉난방 보조 장치의 전체 구성을 나타내는 도면이다. 1 is a view showing the overall configuration of the automotive heating and cooling auxiliary apparatus according to an embodiment of the present invention.
도 1을 참조하면, 본 발명의 냉난방 보조 장치는 적어도 일부에 공기 정화 장치(110)가 장착되어 있는 공기 유입관(100), 공기 유입관(100)의 일단에서 분기되는 3개의 관으로서 제1 분기관(200), 제2 분기관(300), 제3 분기관(400)을 포함하여 구성될 수 있다.Referring to FIG. 1, the air-conditioning assistance device of the present invention includes at least one air inlet pipe 100 having an air purifier 110 mounted thereon, and three pipes branching from one end of the air inlet pipe 100. It may be configured to include a branch pipe 200, the second branch pipe 300, the third branch pipe (400).
본 발명의 일 실시예에 따른 공기 유입관(100)은 외부 공기를 유입시킨다. 즉, 자동차의 운행 시 또는 정지 시에 자동차 외부의 공기가 공기 유입관(100)으로 유입될 수 있게 된다. 공기 유입관(100)의 일단, 즉, 공기가 유입되는 단은 공기 유입이 용이하도록 나팔형으로 형성될 수 있다. 한편, 이러한 공기 유입관(100)의 적어도 일부에는 공기 정화 장치(110)가 장착된다. 공기 정화 장치(110)는 소정 온도 이상, 바람직하게는 250℃ 이상에서 촉매 반응을 함으로써 동작하는 정화 장치이다. 본 발명의 일 실시예에 따르면, LMR(Light Metal Reactor; 경금속 반응기)이 상기 공기 정화 장치(110)로서 사용될 수 있다. 공기 정화 장치(110)의 동작에 대한 상세한 설명은 후술하기로 한다. 공기 정화 장치(110)가 장착된 공기 유입관(100)의 종단, 즉, 공기 유입관(100)의 양단 중 제1 분기관(200), 제2 분기관(300) 및 제3 분기관(400)과 연결된 단에는 밸브(120)가 형성되어 있을 수 있다. 이러한 밸브(120)는 제어부(미도시됨)에서의 제어에 따라 공기 유입관(100)을 제1 분기관(200), 제2 분기관(300) 또는 제3 분기관(400) 중 일 이상의 관과 연결하거나 폐쇄시키는 기능을 수행한다. The air inlet pipe 100 according to an embodiment of the present invention introduces external air. That is, when the vehicle is driven or stopped, air outside the vehicle may be introduced into the air inlet pipe 100. One end of the air inlet pipe 100, that is, the end into which air is introduced, may be formed in a trumpet shape to facilitate air inflow. On the other hand, at least a portion of the air inlet pipe 100 is equipped with an air purification apparatus 110. The air purifier 110 is a purifier that operates by performing a catalytic reaction at a predetermined temperature or higher, preferably at 250 ° C or higher. According to one embodiment of the present invention, LMR (Light Metal Reactor) may be used as the air purification device (110). A detailed description of the operation of the air purification device 110 will be described later. The first branch pipe 200, the second branch pipe 300, and the third branch pipe of both ends of the air inlet pipe 100 equipped with the air purification device 110, that is, the air inlet pipe 100 ( The valve 120 may be formed at the end connected to the 400. The valve 120 is one or more of the air inlet pipe 100, the first branch pipe 200, the second branch pipe 300 or the third branch pipe 400 under the control of a controller (not shown). It performs the function of connecting or closing the pipe.
본 발명의 일 실시예에 따른 제1 분기관(200)은 공기 유입관(100)으로 유입되어 공기 정화 장치(110)에 의해 정화된 공기가 흘러 배출되는 관으로서 제1 분기관(200)의 종단에서 배출되는 공기는 자동차 내의 히터 열로서 사용될 수 있다. 전술한 바와 같이, 공기 정화 장치(110)는 소정 온도 이상에서 동작하기 때문에, 공기 정화 장치(110)를 거쳐 나온 공기는 소정 값 이상의 온도를 갖게 된다. 따라서, 공기 정화 장치(110)를 빠져나온 공기가 바로 히터 열로서 사용될 수 있게 되는 것이다. 그러나, 공기 정화 장치(110)를 빠져 나온 공기는 여러가지 이유에 의해 냉각(예를 들면, 제1 분기관(200)으로 유입되는 과정 또는 제1 분기관(200)을 거치는 과정에서의 냉각)될 수 있는데 이러한 경우에는 제1 분기관(200)을 빠져 나오는 공기를 바로 히터 열로 사용할 수 없게 된다. 따라서, 냉각된 공기를 다시 가열시키기 위한 수단으로서 제1 분기관(200)의 적어도 일부는 자동차의 엔진(500)과 인접하게 형성될 수 있다. 또는, 제1 분기관(200)의 적어도 일부에 엔진(500)으로부터 유도되는 냉각수가 유입되는 냉각수 유입관이 형성될 수도 있다. 즉, 제1 분기관(200)을 통과하는 공기가 엔진(500)의 자체 열 또는 엔진(500)으로부터 유도되는 냉각수와의 열교환에 의해 가열된 후, 제1 분기관(200)을 빠져 나감으로써 히터 열로 사용될 수도 있다. 이러한 제1 분기관(200)과 공기 유입관(100) 간의 연결 또는 폐쇄는 밸브(120)에 의해 실현될 수 있다. 구체적으로 설명하면, 자동차 실내 난방 블로어 스위치가 온 상태일 경우에는 제어부의 제어에 따라 밸브(120)가 제1 분기관(200)을 공기 유입관(100)과 연결시키고 그렇지 않을 경우에는 밸브(120)가 제1 분기관(200)과 공기 유입관(100)을 폐쇄시킬 수 있다. The first branch pipe 200 according to an embodiment of the present invention is a pipe through which the air purified by the air purification apparatus 110 flows into the air inlet pipe 100 and is discharged from the first branch pipe 200. The air exhausted at the end can be used as heater heat in the motor vehicle. As described above, since the air purifier 110 operates at a predetermined temperature or more, the air that has passed through the air purifier 110 has a temperature of a predetermined value or more. Therefore, the air exiting the air purifier 110 can be used as the heater heat. However, the air exiting the air purifier 110 may be cooled (for example, in the process of flowing into the first branch pipe 200 or the process of passing through the first branch pipe 200) for various reasons. In this case, the air exiting the first branch pipe 200 may not be used as a heater heat. Accordingly, at least a part of the first branch pipe 200 may be formed adjacent to the engine 500 of the vehicle as a means for heating the cooled air again. Alternatively, a coolant inflow pipe through which the coolant derived from the engine 500 flows may be formed in at least a portion of the first branch pipe 200. That is, the air passing through the first branch pipe 200 is heated by heat exchange with the heat of the engine 500 itself or cooling water derived from the engine 500, and then exits the first branch pipe 200. It can also be used as a heater heat. The connection or closing between the first branch pipe 200 and the air inlet pipe 100 may be realized by the valve 120. Specifically, when the vehicle indoor heating blower switch is in the on state, the valve 120 connects the first branch pipe 200 to the air inlet pipe 100 according to the control of the controller. ) May close the first branch pipe 200 and the air inlet pipe 100.
다음으로 본 발명의 일 실시예에 따른 제2 분기관(300)은 공기 정화 장치(110)를 통과한 공기를 자동차 실내로 전달하는 기능을 수행한다. 공기 정화 장치(110)를 통과한 공기는 실온 이상이나, 제2 분기관(300)을 통과하면서 일정 정도 냉각될 수 있게 되고, 이러한 공기가 그대로 자동차 실내로 유입될 수 있다. 제2 분기관(300)과 공기 유입관(100)과의 연결 또는 폐쇄 또한 밸브(120)에 의해 실현될 수 있다. 즉, 자동차 실내의 외부 공기 유입 스위치가 온 상태일 경우에는 제어부의 제어에 따라 밸브(120)가 제2 분기관(300)을 공기 유입관(100)과 연결시키고 그렇지 않을 경우에는 밸브(120)가 제2 분기관(300)과 공기 유입관(100)을 폐쇄시킬 수 있다.Next, the second branch pipe 300 according to an embodiment of the present invention performs a function of transferring the air passing through the air purification device 110 to the vehicle interior. The air passing through the air purification device 110 may be cooled to a certain degree while passing through the second branch pipe 300 at room temperature or higher, and the air may be introduced into the vehicle interior as it is. Connection or closing of the second branch pipe 300 and the air inlet pipe 100 may also be realized by the valve 120. That is, when the external air inlet switch of the vehicle interior is turned on, the valve 120 connects the second branch pipe 300 to the air inlet pipe 100 under the control of the controller. The second branch pipe 300 and the air inlet pipe 100 may be closed.
본 발명의 일 실시예에 따른 제3 분기관(400) 또한 공기 유입관(100)을 흘러나온 공기를 배출시키는 역할을 수행하는 관이다. 제3 분기관(400)의 종단에서 배출되는 공기는 자동차 내의 에어컨 공기로서 사용될 수 있다. 공기 정화 장치(110)를 거쳐 나온 공기는 소정 값 이상의 온도 또는 실온 이상의 온도를 갖게 되는데, 이러한 공기는 에어컨 공기로서 사용되기 부적합한 면이 있다. 따라서, 제3 분기관(400)의 적어도 일부에는 제3 분기관(400)을 통과하는 공기를 냉각시키기 위한 수단이 형성되어 있을 수 있다. 일례로서, 도 1에 도시되는 바와 같이, 제3 분기관(400)의 적어도 일부에는 자동차에서의 압축된 냉매가 통과하는 냉매 유입관(410)이 형성되어 있을 수 있다. 이에 따르면, 공기 정화 장치(110)에 의해 정화된 공기가 제3 분기관(400)을 통과하면서 압축된 냉매와의 열 교환에 의해 냉각된 후 제3 분기관(400)을 빠져 나오면서 에어컨 공기로 사용될 수 있는 상태가 된다. 제3 분기관(400)과 공기 유입관(100) 간의 연결 또는 폐쇄 역시 밸브(120)에 의해 선택적으로 구현될 수 있다. 즉, 자동차 실내 냉방 블로어 스위치가 온 상태일 경우에는 제어부의 제어에 따라 밸브(120)가 제3 분기관(400)을 공기 유입관(100)과 연결시키고 그렇지 않을 경우에는 밸브(120)가 제3 분기관(400)과 공기 유입관(100)을 폐쇄시킬 수 있다. 한편, 냉매 유입관(410)으로의 냉매 유입 또한 별도의 밸브(미도시됨)에 의해 제어될 수 있다. 즉, 자동차 실내 냉방 블로어 스위치가 온 상태일 경우에만 밸브가 개방되어 냉매 유입관(410)으로 냉각수가 유입될 수 있게 된다.The third branch pipe 400 according to an embodiment of the present invention is also a pipe that serves to discharge the air flowing out of the air inlet pipe 100. Air discharged from the end of the third branch pipe 400 may be used as air conditioning air in the vehicle. The air that has passed through the air purifier 110 may have a temperature of a predetermined value or more or a temperature of room temperature or more. Such air may be unsuitable to be used as air conditioner air. Therefore, at least a part of the third branch pipe 400 may be provided with means for cooling the air passing through the third branch pipe 400. As an example, as shown in FIG. 1, at least a portion of the third branch pipe 400 may have a refrigerant inlet pipe 410 through which the compressed refrigerant in the vehicle passes. Accordingly, the air purified by the air purifier 110 is cooled by heat exchange with the compressed refrigerant while passing through the third branch pipe 400, and then exits the third branch pipe 400 as air conditioner air. The state can be used. Connection or closing between the third branch pipe 400 and the air inlet pipe 100 may also be selectively implemented by the valve 120. That is, when the automotive air conditioner blower switch is turned on, the valve 120 connects the third branch pipe 400 to the air inlet pipe 100 under the control of the controller. The three branch pipe 400 and the air inlet pipe 100 may be closed. On the other hand, the refrigerant flow into the refrigerant inlet pipe 410 may also be controlled by a separate valve (not shown). That is, the valve is opened only when the vehicle interior cooling blower switch is turned on, so that the coolant may flow into the refrigerant inlet pipe 410.
이하에서는, 공기 정화 장치(110)의 상세 구성 및 동작 원리에 대해 상세히 설명하기로 한다.Hereinafter, the detailed configuration and operation principle of the air purification device 110 will be described in detail.
공기 정화 장치Air filter
본 발명에서의 공기 정화 장치는 본 출원인이 기 출원한 한국특허출원 제2009-0036439호("세라믹 피막을 이용한 담체 구조와 그 담체의 제조 방법")에 개시되어 있는 공기 정화용 담체에 기초하고 있다. 본 출원인은 종래 공기 정화용 담체를 개선한 상기 출원에 기재되어 있는 공기 정화용 담체, 즉, 경금속임과 동시에 열전도율이 뛰어나 공기 정화 장치에서 촉매반응을 일으킬 수 있는 온도까지 올라가는 데 소요되는 시간을 현저히 줄일 수 있는 알루미늄을 적용한 공기 정화용 담체를 LMR(Light Metal Reactor; 경금속 반응기)이라 칭하기로 한다.The air purifying apparatus in the present invention is based on the air purifying carrier disclosed in Korean Patent Application No. 2009-0036439 ("Carrier Structure Using Ceramic Coating and Manufacturing Method of the Carrier") filed by the present applicant. The present applicant can significantly reduce the time required to raise the temperature of the air purification carrier described in the above application, that is, a light metal and excellent thermal conductivity, which can cause a catalytic reaction in the air purification device. An air purification carrier to which aluminum is applied will be referred to as LMR (Light Metal Reactor).
이러한 공기 정화 장치(110)에는 세라믹 피막이 적용되는데 이하 세라믹 피막에 대해 간단히 설명하기로 한다. A ceramic coating is applied to the air purifier 110. Hereinafter, the ceramic coating will be briefly described.
공기 정화 장치(110)에 사용되는 세라믹 피막은 전도성 금속을 이용하여 제조될 수 있는데, 일례로서, 경금속인 알루미늄이 사용될 수 있다. 이러한 세라믹 피막의 제조 과정을 설명하면 다음과 같다. 이하의 설명에서, 세라믹 피막의 제조에 사용되는 전도성 금속은 알루미늄인 것으로 예를 들어 설명하기로 한다. 먼저, 속이 빈 원기둥 형태의 알루미늄 관을 준비하고, 내외부를 탈지한다. 그 후, 에칭 등의 방법으로 알루미늄에 함유된 금속 산화물들을 제거하고, 약산성 용액으로 디스머트하여 불용성 물질 또한 제거해낸다. 다음으로, 알루미늄 관 내부의 중심에 알루미늄 선 또는 알루미늄 철사를 배치하여 음극 전류를 인가하고, 알루미늄 관에는 양극 전류를 인가한다. 또한, 알루미늄 관의 내부에 전해액을 순환시켜 전체적으로 양극 산화 반응이 발생할 수 있도록 한다. 양극 산화 반응에 의해 음극 전류가 인가된 알루미늄 선 또는 철사 주위에서는 수소가 발생하고, 양극 전류가 인가된 알루미늄 관에서는 산소가 발생하게 된다. 이러한 산소는 알루미늄 관과 반응하게 되는데, 이에 따라 알루미늄 관의 내벽에는 산화 알루미늄인 알루미나가 서서히 적층되게 되며, 이는 알루미나 피막으로서 형성된다.The ceramic coating used for the air purification apparatus 110 may be manufactured using a conductive metal. For example, aluminum, which is a light metal, may be used. Referring to the manufacturing process of such a ceramic film is as follows. In the following description, the conductive metal used in the manufacture of the ceramic coating is described as an example of aluminum. First, a hollow cylindrical aluminum tube is prepared, and the inside and the outside are degreased. Thereafter, metal oxides contained in aluminum are removed by etching or the like, and then immersed in a weakly acidic solution to remove insoluble materials. Next, an aluminum wire or an aluminum wire is disposed in the center of the aluminum tube to apply a cathode current, and an anode current is applied to the aluminum tube. In addition, the electrolyte is circulated inside the aluminum tube so that the anodization reaction may occur as a whole. Hydrogen is generated around the aluminum wire or wire to which the cathode current is applied by the anodic oxidation reaction, and oxygen is generated to the aluminum tube to which the anode current is applied. This oxygen reacts with the aluminum tube, whereby alumina, which is aluminum oxide, is gradually deposited on the inner wall of the aluminum tube, which is formed as an alumina film.
양극 산화 반응의 과정에서 전해액은 상기 형성된 알루미나 피막을 미세하게 용해시키게 되는데, 이러한 용해 속도와 알루미나 피막의 성장 속도가 균형을 이루게 되면, 알루미나 피막에 약 10~150㎛ 의 직경을 갖는 균일한 기공들이 형성되게 된다. 즉, 양극 산화 반응을 통해 균일한 기공이 형성된 두꺼운 알루미나 피막이 알루미늄 관 내벽에 형성될 수 있게 되며, 이러한 다공질의 알루미늄 피막이 공기 정화 장치(110)에 적용되는 세라믹 피막으로서 기능할 수 있게 된다. During the anodic oxidation reaction, the electrolyte solution dissolves the formed alumina film finely. When the dissolution rate and the growth rate of the alumina film are balanced, uniform pores having a diameter of about 10 to 150 μm are formed in the alumina film. Will be formed. That is, a thick alumina film having uniform pores formed through the anodic oxidation reaction may be formed on the inner wall of the aluminum tube, and the porous aluminum film may function as a ceramic film applied to the air purification device 110.
이하에서는, 상기 설명한 방법에 따라 얻어진 세라믹 피막을 이용하여 공기 정화 장치(110)로서의 담체에 대해 설명하기로 한다.Hereinafter, the carrier as the air purification device 110 will be described using the ceramic film obtained according to the above-described method.
공기 정화 장치(110)로서 사용되는 담체의 제조 과정을 설명하면 다음과 같다. 먼저, 전술한 과정에 따라 제조된 알루미나 피막으로서 형성된 세라믹 피막의 내벽과 외벽에 기체 반응에 활성을 가지고 있는 귀금속 계열의 촉매 모액을 담지시켜 촉매층을 형성시킨다. 이때, 백금 또는 로듐의 혼합물 용액 등의 촉매 모액을 담지시켜 상기 촉매층을 형성할 수 있다. 이는 아래에서 보다 상세히 기술하기로 한다. Referring to the manufacturing process of the carrier used as the air purification apparatus 110 as follows. First, a catalyst layer is formed on an inner wall and an outer wall of a ceramic film formed as an alumina film prepared according to the above process by supporting a catalyst mother liquid of a noble metal series having an active gas reaction. In this case, the catalyst layer may be formed by supporting a catalyst mother liquid such as a mixture solution of platinum or rhodium. This will be described in more detail below.
그 후, 이를 공기 흐름 하에서 450℃로 12시간 동안 소성시켜 결정 구조를 성장시킨다.Thereafter, it is calcined at 450 ° C. for 12 hours under air flow to grow a crystal structure.
이렇게 제조된 담체는, 금속기질에 박막의 형태로 존재함으로 열용량이 낮은 세라믹에 비하여 열 전도도가 우수하여 쉽게 고온에 도달될 수 있고, 이에 따라 고온에서 얻을 수 있는 여러가지 이점을 얻을 수 있으며, 그 성능을 극대화할 수 있다.Since the carrier is prepared in the form of a thin film on a metal substrate, the thermal conductivity of the carrier can be easily reached at a high temperature compared to a ceramic having a low heat capacity, and thus, various advantages that can be obtained at a high temperature can be obtained. Can be maximized.
한편, 이러한 세라믹 피막에 있어서는, 기질에 촉매층이 분자 단계의 결합을 유지하기 때문에 물리적 충격에 매우 강해지게 된다.On the other hand, in such a ceramic film, since the catalyst layer maintains the bond of the molecular step to the substrate, it is very resistant to physical impact.
이상에서는 세라믹 피막의 형성에 사용되는 금속으로써, 알루미늄을 예로 들어 설명하였으나, 이에 한정되는 것은 아니고, 티타늄 또는 질코늄과 같이 금속산화물의 형성이 가능한 어떠한 금속도 사용될 수 있음은 물론이다.In the above, as the metal used to form the ceramic coating, the aluminum has been described as an example. However, the present invention is not limited thereto, and any metal capable of forming a metal oxide such as titanium or zirconium may be used.
한편, 공기 정화 장치(110)로서 사용되는 담체는 다음과 같은 형상으로 형성될 수 있다. On the other hand, the carrier used as the air purification device 110 may be formed in the following shape.
도 2를 참조하여 설명하면, 본 발명의 다른 실시예에 따른 담체는 '체'와 같은 형태의 격자(a)가 소정 높이로 형성된 형태일 수 있다. 이에 따르면, 세라믹 피막의 표면적이 상대적으로 넓어지게 되고, 기체 반응의 효율이 향상될 수 있게 된다. 도 2에 도시되에 있는 담체에 있어서 A-A'선을 따라 절단하여 바라본 단면도는 도 3과 같다. Referring to FIG. 2, the carrier according to another embodiment of the present invention may have a shape in which a lattice a having a shape such as a 'sieve' is formed at a predetermined height. According to this, the surface area of the ceramic film becomes relatively large, and the efficiency of gas reaction can be improved. 3 is a cross-sectional view taken along the line A-A 'of the carrier shown in FIG.
도 3을 참조하면, 격자(a)는 담체 모듈이 적층되는 높이 방향과 소정 각도 기울어지게 형성된다. 이는 상기 담체 모듈의 밑변과 수직되게 격자를 쌓아올린 경우와 비교하여, 기체 반응 물질이 세라믹 피막과 접촉하는 면적을 증가시켜, 반응 효율을 증가시키는 효과 외에, 반응 물질이 상기 담체 모듈을 통과하면서 상기 격자에 부딪혀 난류 또는 난반사 등을 발생시킴으로써, 반응 물질이 상기 담체 내부에서 이동하는 경로를 증가시켜, 전체적인 반응 효율을 증가시키는 효과를 얻을 수도 있다.Referring to FIG. 3, the grating a is formed to be inclined at a predetermined angle with a height direction in which the carrier modules are stacked. Compared to the case where the lattice is stacked vertically with the base of the carrier module, the area in which the gaseous reaction material contacts the ceramic coating is increased, and in addition to the effect of increasing the reaction efficiency, the reaction material passes through the carrier module. By hitting the lattice and generating turbulence or diffuse reflection, the path of the reaction material moving inside the carrier may be increased, thereby increasing the overall reaction efficiency.
도 3은 도 2의 격자 표면을 확대하여 도시한 도면이다.3 is an enlarged view of the grating surface of FIG. 2.
도 3을 참조하면, 상기 격자(a) 표면은 베이스를 형성하는 금속층(610)과 상기 금속층(610) 위에 금속층(610)을 구성하는 금속과 상기 금속의 산화물이 공존하는 전이층(620) 및 전이층(620) 위에 다공질의 세라믹 피막층(630)이 형성된다. 상기 금속층(610)을 구성하는 금속으로는 알루미늄, 티타늄, 또는 질코늄이 사용될 수 있다.Referring to FIG. 3, the surface of the lattice a may include a metal layer 610 forming a base, a transition layer 620 on which the metal constituting the metal layer 610 coexists with an oxide of the metal on the metal layer 610; The porous ceramic coating layer 630 is formed on the transition layer 620. Aluminum, titanium, or zirconium may be used as the metal constituting the metal layer 610.
한편, 상기 세라믹 피막층(630)의 기공 사이사이에는 백금(Pt) 또는 로듐(Rh) 촉매층이 삽입될 수 있다. 상기 촉매층은 촉매 모액을 담지시켜 촉매층을 형성한 후 건조시켜 형성된다.Meanwhile, a platinum (Pt) or rhodium (Rh) catalyst layer may be inserted between the pores of the ceramic coating layer 630. The catalyst layer is formed by supporting the catalyst mother liquid to form a catalyst layer and then drying.
일례로서, 담체가 배기가스의 정화에 사용되는 경우를 가정하면, 상기 백금 촉매는 배기가스를 구성하는 CO를 CO2로 전환하거나, Hydro C를 H2O 또는 CO2로 분해하는데 사용될 수 있다. 한편, 상기 로듐 촉매는 NOX를 N2로 분해하는데 사용될 수 있다. As an example, assuming that a carrier is used to purify exhaust gas, the platinum catalyst may be used to convert CO constituting the exhaust gas into CO 2 or to decompose Hydro C into H 2 O or CO 2 . On the other hand, the rhodium catalyst can be used to decompose NOx to N2.
한편, 도 4는 본 발명의 또 다른 실시예에 따른 세라믹 피막이 형성된 담체의 제조과정을 도시한 도면이고, 도 5 및 도 6은 도 4에 개시된 방법으로 제조된 세라믹 피막이 형성된 담체의 구조를 도시한 도면이다.On the other hand, Figure 4 is a view showing the manufacturing process of the carrier with a ceramic film formed according to another embodiment of the present invention, Figure 5 and Figure 6 shows the structure of the carrier with a ceramic film formed by the method disclosed in FIG. Drawing.
도 4 내지 도 6을 참조하면, 담체는 다음과 같은 방법으로 제조될 수 있다. 먼저, 금속판(710) 상에 프레스 가공 등을 통해 천공(720)을 형성시킨다. 이러한 천공(720)은 주전자 뚜껑에서 김이 빠지는 구멍과 그 형태가 유사할 수 있다. 천공(720)이 형성된 상기 금속판(710) 하부에 외부 공기에 포함된 분진 등과 같은 불순물을 필터링하기 위한 ‘체’형태의 메탈 폼(metal foam;730)이 형성된다.4 to 6, the carrier may be prepared by the following method. First, the perforation 720 is formed on the metal plate 710 by press working or the like. The perforation 720 may be similar in shape to a hole where steaming is removed from the kettle lid. A metal foam 730 having a 'sieve' shape is formed under the metal plate 710 on which the perforations 720 are formed to filter impurities such as dust contained in the outside air.
천공(720)을 형성한 후에는, 담체 구조를 양극산화하여 세라믹 피막을 형성하고, 세라믹 피막의 내벽과 외벽에 기체 반응의 활성을 가지고 있는 귀금속 계열의 촉매 모액을 담지시켜 촉매층을 형성시킨다. 이는 앞서 설명한 담체의 제조 과정과 동일하다.After the perforation 720 is formed, the carrier structure is anodized to form a ceramic film, and a catalyst layer is formed by supporting a catalyst mother liquid of a noble metal series having gaseous activity on the inner and outer walls of the ceramic film. This is the same as the manufacturing process of the carrier described above.
한편, 이렇게 형성된 담체를 스파이럴(spiral) 형태로 롤링하여 원통형상의 담체 구조를 형성한다. 이렇게 제조된 담체 구조가 도 5 및 도 6에 개시되었다.Meanwhile, the carrier thus formed is rolled into a spiral form to form a cylindrical carrier structure. The carrier structure thus prepared is disclosed in FIGS. 5 and 6.
반응 대상 물질(외부 공기)은 원통형의 담체와 수직으로 즉, 원형의 단면을 통과하도록 진행하며 이 과정에서 수많은 천공(720) 속을 관통하여 진행하게 된다. 상기 천공(720) 속으로 진입한 반응 대상 물질은 금속판(710)의 하부에 형성되는 메탈 폼(730)의 격자 구조에 의해 분진 등의 불순물이 필터링되고, 기체만이 통과되게 된다. 일반적으로 난류 계열에 속하는 외부 공기는 그 유선이 복잡하게 진행하게 됨으로 진행과정에서 상기 천공(720) 및 메탈 폼(730)을 수없이 거치게 되기 때문에 외부 공기에 포함된 유해 물질이 촉매층과 반응하는 효율이 극대화될 수 있다. 따라서, 담체 구조를 통과한 외부 공기는 불순물과 유해 물질이 모두 제거되어 청정한 상태, 즉 공기 정화용 담체에 의해 정화되는 것이다.The reaction target material (outer air) proceeds perpendicularly to the cylindrical carrier, that is, through a circular cross section, and passes through a number of perforations 720 in the process. The reaction target material entering the perforation 720 is filtered by impurities such as dust by the lattice structure of the metal foam 730 formed under the metal plate 710, and only gas passes therethrough. In general, the outside air belonging to the turbulent series has a complicated flow of the streamline, so that the harmful air contained in the outside air reacts with the catalyst layer because it passes through the perforation 720 and the metal foam 730 in progress. This can be maximized. Therefore, the outside air passing through the carrier structure is purged by the carrier for purification, that is, all impurities and harmful substances are removed.
한편, 경우에 따라서는 상기 메탈 폼만을 양극산화하여 세라믹 피막을 형성하고, 촉매층을 형성한 뒤 스파이럴 형태로 롤링하여 원통형상의 담체구조를 형성하는 것도 가능하다.On the other hand, in some cases, it is also possible to anodize only the metal foam to form a ceramic film, to form a catalyst layer, and then roll in a spiral shape to form a cylindrical carrier structure.
이렇게 다양한 방식으로 제조되는 공기 정화용 담체가 본 발명의 공기 정화 장치(110)로 이용될 수 있는 것이다.Carrier for air purification produced in various ways can be used as the air purification device 110 of the present invention.
한편, 상기 설명한 공기 정화용 담체 외에도 다른 방식, 예를 들면, 세라믹을 주 재료로 생산하는 방식인 담체가 공기 정화 장치(110)에 적용될 수도 있음은 물론이다.On the other hand, in addition to the above-described carrier for air purification, a carrier, which is another method, for example, a method of producing ceramic as a main material, may be applied to the air purification apparatus 110.
