Abstract
본 고안은 광촉매의 강한 산화력을 이용하여 대기오염의 주요원인으로 알려지고 있는 휘발성 유기 화합물질 (Volatile Organic Compounds : VOC's)등의 대기오염물질을 효과적으로 처리할 수 있는 농축에 의한 대기오염 방지장치에 관한 것으로 더욱 상세하게는, 오염물질이 포함된 외기가 강제 송풍기를 통해서 흡탈착처리조에 공급되어 흡착반응과 탈착반응이 시간간격을 두고 일어나는 흡착제충진부와, 상기 흡탈착처리조에 연결되어 가열봉에 의해 탈착반응을 일어나서 탈착된 오염물질인 유해가스가 연통 연결되어진 광촉매 분해반응조로 유입되고; 유입된 오염물질인 유해가스를 광촉매 (TiO2)를 함유하고 있고 중심에 자외선 램프가 설치된 광촉매 분해반응조를 통과시킴으로서, 우수한 탈착효율과 소비되는 전력량을 감소시킬 수 있고, 분해효율이 증대하면서도 자외선램프을 단 한 개만 사용함으로써 투자 및 운전비용을 낮출 수 있는 효과가 있는 농축에 의한 대기오염 방지장치를 제공하는 것이다.The present invention relates to an air pollution prevention device by concentration that can effectively process air pollutants such as volatile organic compounds (VOC's), which are known as the main causes of air pollution by using the strong oxidation power of photocatalyst. More specifically, the air containing contaminants is supplied to the adsorption and desorption tank through a forced blower, and the adsorbent filling unit in which adsorption and desorption reactions are spaced at a time interval, and connected to the adsorption and desorption tank, is heated by a heating rod. A desorption reaction occurs and harmful gases, which are desorbed pollutants, are introduced into the photocatalytic decomposition reaction tank connected to each other; By passing photocatalyst decomposition reaction tank containing photocatalyst (TiO 2 ) and UV lamp installed in the center, it can reduce the desorption efficiency and power consumption, and increase the decomposition efficiency while increasing the decomposition efficiency.

Description
본 고안은 입자가 아닌 가스상의 대기오염물질을 처리하는 장치에 관한 것으로, 보다 상세히는 생활수준 향상과 더불어 삶의 질적수준 향상을 위해 그 처리가 요구되는 악취물질 및 지구오존층파괴, 산성비, 지구 온난화 등의 주요원인으로 알려지고 있는 휘발성 유기화합물질(Volatile Organic Compounds : VOC's )등의 대기오염물질을 효과적으로 처리할 수 있는 대기오염방지를 위한 장치로써, 저농도로 분포된 오염물질을 흡입하여 고농도로 농축한 후 이를 광촉매의 산화력을 이용하여 분해시켜 대기중으로 방출되는 것을 방지하여 대기오염을 예방할 수 있는 대기오염물질 제거장치에 관한 것이다.The present invention relates to a device for treating gaseous air pollutants rather than particles, and more specifically, odorous substances and global ozone layer destruction, acid rain and global warming, which are required for treatment to improve living standards and quality of life. It is a device to prevent air pollution that can effectively treat air pollutants such as volatile organic compounds (VOC's), which are known to be the main cause. The present invention relates to an air pollutant removal device capable of preventing air pollution by decomposing it by oxidizing power of a photocatalyst and preventing it from being released into the atmosphere.
일반적으로 휘발성 유기 화합물질(VOC ;Volatile Organic Compound)등과 같은 대기오염물질을 제거하는 방법은 오염물질을 흡착 또는 연소시키는 방법이 가장 일반적인 방법으로 사용되어 왔으나, 흡착을 이용하는 경우 가장 보편적으로 사용되는 활성탄의 경우 용해도가 큰 친수성 물질 및 작은 분자에 관하여는 거의 효과가 없으며, 포화 흡착 후에는 이의 처리과정에서 또 다른 2차 오염물질의 발생으로 인하여 문제가 되고 있으며, 합성분자제(Zeolite)와 같은 일정한 기공분포 및 특성을 부여할 수 있는 흡착제의 경우 재생이 가능하고 선택성을 가지고 오염물질을 흡착 및 재생을 할 수 있으나 지나치게 고가이며, 이의 회수시 재사용이 가능한 경우를 제외하고는 이를 처리하기 위한 후처리 시설의 비용이 지나치게 과다하거나또 다른 처리를 필요로하는 등의 문제점이 있다.Generally, the method of removing air pollutants such as volatile organic compounds (VOCs) has been the most common method of adsorbing or burning pollutants, but the most commonly used activated carbon is used for adsorption. In case of hydrophilic substances and small molecules with high solubility, they have little effect, and after saturation adsorption, there is a problem due to the occurrence of another secondary pollutant in the treatment process. Adsorbents that can impart pore distribution and properties can be regenerated and have the selectivity to adsorb and regenerate contaminants, but are too expensive and are post-treatment to treat them except when they can be reused in recovery. The cost of the facility is excessively excessive or requires another treatment. There is a problem.
또한 연소 방법의 경우는 고온연소의 경우 제거 효율이 우수하지만 연소시 질소산화물(NOx) 다이옥신(Dioxine)등이 발생하여 또 다른 환경오염을 유발할 수도 있으며, 촉매를 이용한 저온 연소의 경우는 일정 농도 이상이 유지되지 못하면 연료비용이 과다하게 소비되며, 촉매독에 의한 피독으로 고가 촉매 교환이 필요한 경우가 많게 된다. 또한, 할로겐화합물 경우 처리가 어려우며, 농도의 변화가 심할 시에는 촉매가 파손되는 등의 공정 유동성이 낮은 문제점이 있으며, 연소법의 경우 설치 및 운전비용이 지나치게 높아 경제적이지 못한 문제점이 있었다.In addition, in the case of the combustion method, the removal efficiency is excellent in the case of high temperature combustion, but when combustion, nitrogen oxides (NOx) and dioxine may be generated, which may cause another environmental pollution. If this is not maintained, fuel costs are excessively consumed, and expensive catalyst exchange is often required due to poisoning by the catalyst poison. In addition, in the case of a halogen compound, it is difficult to process, and when the concentration change is severe, there is a problem of low process fluidity such as breakage of the catalyst, and in the case of the combustion method, there is a problem in that the installation and operation costs are too high and it is not economical.
이러한 문제점을 극복할 수 있는 대안으로서 광촉매를 이용한 오염물질의 제거 방법이 대두되고 있는데, 이러한 광촉매 산화법이라함은, 일정한 담지체에 지지되어 있는 반도체적 특징을 가지는 광촉매(TiO2)에 일정한 파장(380nm이하)의 빛을 조사하면, 최외곽의 전자가 전도대의 에너지준위로 여기되어 기저상태의 에너지준위에는 정공(hole)이 생성되며, 상기 전자와 정공(hole)은 촉매의 표면으로 이동하면서 전자와 정공이 재결합되지 않고 표면에 도달한 정공(hole)은 표면에 흡착된 오염물질을 직접 산화시키거나(이를 Primary Oxidation이라 한다), 물(H20) 또는 과산화수소(H2O2) 등으로부터 수산화 자유기(Hydroxyl Radical ; OH·)가 형성되는데 이 수산화 자유기는 강한 산화력을 가지고 있어서, 오염물질의 분해가 이루어지게 되고(이를 Secondary Oxidation 이라한다.), 이와 같은 산화방법의 결과는 일반적 연소에서와 마찬가지로 이산화탄소(CO2) 및 물(H2O)로 전환되지만 그 처리과정(Mechanism)에 있어서는 완전히 다른 것이다.As an alternative to overcome this problem, a method of removing contaminants using a photocatalyst has emerged. The photocatalytic oxidation method is characterized in that the photocatalyst (TiO 2 ) having a semiconductor characteristic supported on a certain carrier has a constant wavelength ( 380nm or less), the outermost electron is excited to the energy level of the conduction band, and holes are generated at the energy level of the ground state, and the electrons and holes move to the surface of the catalyst Holes that reach the surface without recombination with holes directly oxidize contaminants adsorbed on the surface (called Primary Oxidation), or from water (H 2 0) or hydrogen peroxide (H 2 O 2 ). Hydroxyl Radical (OH ·) is formed, which has strong oxidizing power, so that decomposition of pollutant is made (this is called Secondary Oxidation). C), the result of this oxidation process is converted to carbon dioxide (CO 2 ) and water (H 2 O) as in normal combustion, but completely different in its mechanism.
상기와 같은 광촉매의 산화방법에 의한 오염물질의 제거방법이 많은 장점을 가지면서도 상업화가 이루어지지 못하고 있는 이유는 한마디로 표면반응이기 때문이라고 할 수 있다.Although the method of removing contaminants by the oxidation method of the photocatalyst has many advantages, commercialization cannot be achieved because it is a surface reaction.
즉, 일정한 에너지 이상으로 조사된 빛을 받아 촉매가 활성화 되어 반응이 일어나는 곳이 표면이기 때문에, 표면에 분해대상 물질이 흡착되어야만 분해가 가능해 지는데, 촉매의 표면을 무작정 늘릴 수 없으며 일정 이상의 효율을 얻기 위한 체류시간을 확보하는 문제점이 있어 상업화가 이루어지지 못해왔다.That is, since the surface is the place where the reaction occurs when the catalyst is activated by receiving light irradiated with a certain energy or more, the decomposition is possible only when the substance to be decomposed is adsorbed on the surface. There has been a problem in securing a residence time for commercialization.
이와 같은 문제점을 극복할 수 있는 방안으로, 흡착제 이송을 통한 처리방법 및 농축 후 연속 순환을 하면서 광촉매를 통한 오염물질의 제거 방법 등이 제시되었으나 실용적인 방법이 되지는 못하였다.As a way to overcome this problem, a treatment method through the transfer of the adsorbent and a method of removing contaminants through the photocatalyst while continuously circulating after concentration have been proposed, but it has not been a practical method.
상기 흡착제의 이송방법에 의한 경우, 농도차에 의해서만이 탈착 및 이동되어 탈착율이 낮고, 탈착시간과 반응시간이 동일하여 완전한 처리가 이루어지지 못할 뿐만 아니라, 일정량이 흡착제에 지속적으로 누적됨에 따라 그 실효성이 저하되는 문제점이 있었다.In the case of the adsorbent transfer method, the desorption rate is lowered and moved only by the difference in concentration, so that the desorption rate is low, the desorption time and the reaction time are the same, and thus the complete treatment cannot be achieved. There was a problem that the effectiveness decreased.
그리고, 고농도일 경우에는 촉매표면에 오염물질의 흡착 확률은 높으나 결국에는 오염성분의 가스가 온도 및 농도 확산에 의해서 한 번 지나가는(single pass) 동안 가스 중의 오염물질을 분해, 제거하는 방법으로 제거되는 것과 마찬가지로, 사실상 대부분은 냉각기의 농축에 의한 것으로 농축수의 처리가 필요하며, 흡착제의 이송시 파손으로 인한 먼지 문제 및 흡착제 표면에 고농도의 오염물질로 인하여균일한 가열이 어려워지고 활성이 저하되어 장기적으로는 그 효율을 제대로 발휘하지 못하는 문제점이 있었다.At high concentrations, the probability of adsorption of contaminants on the catalyst surface is high, but eventually, the contaminant gas is removed by decomposing and removing contaminants in the gas during the single pass by temperature and concentration diffusion. Similarly, most of them are due to the condensation of the cooler, which requires the treatment of concentrated water, and due to dust problems caused by breakage during transport of the adsorbent and high concentrations of contaminants on the adsorbent surface, it is difficult to uniformly heat and deteriorate the activity. There was a problem that does not properly exhibit the efficiency.
이러한 문제점을 해소하기위해 선 출원된 실용신안(20-2000-0015103호)이 고안되었으며, 그 구성은 도 1에 도시된 바와 같이 오염물질이 함유된 외기가 선택적으로 공급되고, 내부공간에 일정량의 흡착제가 충진되고, 복수개의 가열봉(111)이 수직하게 설치된 제 1,2처리조(10a)(10b)를 각각 갖추어 흡착, 탈착반응이 일정시간을 두고 교번하여 일어나는 흡,탈착처리부(10);와, 상기 제 1,2처리조(10a)(10b)와 연통연결되어 탈착반응으로 탈착된 오염물질을 포함하는 유해가스가 유입되는 산소공급조(121)를 갖추어 상기 유입된 유해가스를 1차로 광분해하면서 온도·수분 조절 및 광촉매 반응기에 필요한 산소(Ox)를 공급하는 산소공급부(12); 및, 상기 산소공급조(121)와 연통연결되어 1차 분해된 유해가스를 2차로 광촉매에 의해 분해하는 광촉매 분해처리조(131)를 갖추어 가스를 재순환시키는 광촉매 분해반응부(13);를 포함하고 있으나, 농축 후 연속적인 순환에 의한 방법의 경우에는 순환으로 인해 열손실이 발생하여 운전에 있어 소요비용이 증가하고, 가열기에 접한 흡착제는 연소로 인하여 흡착제가 파괴되며, 가열기와 떨어진 부분은 탈착이 충분히 이루어지지 못하는 문제점 때문에 효율적인 방법이 되지 못하는 문제점이 있었다.In order to solve this problem, a utility model (20-2000-0015103) filed in advance has been devised, and its structure is selectively supplied with outside air containing contaminants as shown in FIG. Adsorption and desorption treatment unit 10 in which adsorption and desorption reactions alternately take place for a predetermined time by filling adsorbents, and having first and second treatment tanks 10a and 10b respectively provided with a plurality of heating rods 111 vertically. And, the first and second treatment tank (10a) is connected with the oxygen supply tank 121 is connected to the first and second treatment tanks (10a, 10b) containing the pollutants desorbed by the desorption reaction to the introduced harmful gas 1 An oxygen supply unit 12 for supplying oxygen (Ox) necessary for temperature / moisture control and a photocatalytic reactor while photolysis into a car; And a photocatalytic decomposition reaction unit 13 having a photocatalyst decomposition treatment tank 131 connected in communication with the oxygen supply tank 121 to decompose the firstly decomposed harmful gas by a photocatalyst secondly. However, in the case of the method of continuous circulation after concentration, heat loss occurs due to circulation, which increases the operating cost, and the adsorbent in contact with the heater destroys the adsorbent due to combustion, and the part separated from the heater is desorbed. There was a problem that does not become an efficient way because of the problem is not enough.
그리고 고농도로 유지된 상태에서도 광촉매반응에 의하여 10% 이상의 제거가 가능하기 위해서는 물질에 따라 1분∼1시간의 체류시간이 요구되지만 연속적인 순환으로는 이를 만족시킬수가 없으며, 연속적인 순환으로 반응기의 온도가 높아져반응효율을 급격히 감소시키는 등의 문제점으로 인하여 효과적이지 못한 문제점을 가지고 있었다.And in order to be able to remove more than 10% by the photocatalytic reaction even at high concentrations, a residence time of 1 minute to 1 hour is required depending on the material, but this cannot be satisfied by continuous circulation. Due to problems such as a rapid decrease in the reaction efficiency due to the high temperature, there was a problem that is not effective.
따라서, 본 고안은 상기와 같은 종래의 문제점을 해소하기 위하여 제안된 것으로서 ;Therefore, the present invention has been proposed to solve the above conventional problems;

To this end, the adsorption layer is easily minimized by minimizing the thickness of the adsorption layer, while ensuring maximum residence time in the reactor, which is essential for the photocatalytic reaction, and preventing air pollution using a photocatalyst capable of decomposing and removing contaminants in a minimum amount of time. To provide a device.

도면에 도시된 바와 같이 본 고안은 강제송풍기(2)는 오염물질이 포함된 공기를 공급하고, 상기 강제송풍기(2)의 일측에 연결구성된 필터(3)는 오염물질이 포함된 공기 중의 먼지등을 제거하는 것이며, 상기 필터(3)의 일측에 연결구성되는탑형상의 흡탈착처리조(4)는 흡착제(411)가 충진된 흡착제충진부(41)를 소정의 경사각을 갖도록 다수개 설치하고 있고 상기 흡착제충진부(41)의 공간부 사이에 탈착반응을 위한 다수개의 가열봉(412)을 더 설치하고 있으며, 상기 흡탈착처리조(4)의 일측에 상부에 유입로(51)와 하부에 배출로(52)로 연결구성된 분해반응조(5)는 판체형상의 다수개의 격벽(53)이 내벽면을 따라 구성된 L형클램프(531)와 고정클램프(532)를 소정의 경사각을 갖도록 설치하고 상기 격벽(53)의 중앙부를 관통되는 자외선램프(7)를 더 설치하여 이루어진다 .As shown in the drawings, the present invention provides a forced blower 2 to supply air containing contaminants, and a filter 3 connected to one side of the forced blower 2 includes dust in air containing contaminants. The adsorption and desorption tank 4 of the columnar shape configured to be connected to one side of the filter 3 is provided with a plurality of adsorbent fillers 41 filled with the adsorbent 411 to have a predetermined inclination angle. And a plurality of heating rods 412 for the desorption reaction is further installed between the space portion of the adsorbent filling unit 41, the inlet passage 51 and the lower portion on one side of the adsorption and desorption treatment tank (4) The decomposition reaction tank (5), which is connected to the discharge passage (52), has a plurality of plate-shaped partition walls (53) having an L-shaped clamp (531) and a fixed clamp (532) formed along an inner wall surface to have a predetermined inclination angle. Made by installing an ultraviolet lamp 7 penetrating the central portion of the partition 53 All .
상기 흡탈착처리조(4)는 오염물질의 발생원에 설치된 국소배기장치(도면 미도시)로부터 오염물질이 함유된 외부공기가 유입구(42)을 통하여 공급되고, 상기 유입구(42)에는 오염된 외기를 강제로 흡입하는 강제송풍기(2)와 흡입되는 외기내에 포함된 먼지 물질의 경우 흡착제의 성능저하 요인이 되므로 이를 여과할 수 있도록 먼지의 성상에 따라 필터(3)을 구성할 수 있다The adsorption and desorption treatment tank 4 is supplied with external air containing contaminants from the local exhaust device (not shown) installed at the source of the pollutant through the inlet port 42, and contaminated outdoor air is supplied to the inlet port 42. In the case of the forced blower (2) forcibly suctioning and the dust material contained in the suctioned outside air is a deterioration factor of the adsorbent, it is possible to configure the filter (3) according to the properties of the dust to filter it
이러한 필터(3)은 프리필터(Pre-filter) 또는 미듐필터(Medium filter)등를 사용 설치하는 것이 바람직하다.The filter 3 is preferably installed using a pre-filter or a medium filter.
상기 강제송풍기(2)는 오염물질 발생원의 체적에 따른 환기회수 및 국소배기장치(도면 미도시)의 형상에 따라 압력손실, 유인관의 직경, 거리 및 속도 압력손실, 장치를 포함한 유로에서의 압력손실, 오염공기의 중량 등을 고려하여 송풍기의 압력, 속도, 풍량를 결정한다.The forced blower (2) has a pressure loss, a diameter of the attraction pipe, a distance and speed pressure loss, and a pressure loss in the flow path including the device according to the ventilation recovery according to the volume of the pollutant source and the shape of the local exhaust device (not shown). Determine the pressure, speed, and air volume of the blower by considering the weight of polluted air.
도 4에 도시된 바와 같이 본 고안은 오염물질이 포함된 공기를 공급하는 강제송풍기(2)를 통하여 오염물질이 포함된 공기를 먼지등을 제거하는 필터(3)에 강제 송풍하고 상기 필터(3)에 의해 먼지등이 제거된 오염물질이 포함된 공기를 탑형상의 흡탈착처리조(4)에 공급하여 소정의 경사각을 갖도록 다수개 설치되는 흡착제(411)가 충진된 흡착제충진부(41)를 통과하면서 흡착제(411)에 오염물질이 흡착되어 정화된 공기를 흡탈착처리조(4)의 상부에 형성된 배기구(43)로 배출하게되는 것이다.As shown in FIG. 4, the present invention forcibly blows air containing contaminants to a filter 3 for removing dust and the like through a forced blower 2 for supplying air containing contaminants and the filter 3. Adsorbent filling unit 41 is filled with a plurality of adsorbents 411 are installed to supply air containing contaminants from which dust is removed by a) to the tower-shaped adsorption and desorption treatment tank (4) to have a predetermined inclination angle Contaminants are adsorbed to the adsorbent 411 while passing through the air to discharge the purified air to the exhaust port 43 formed at the upper portion of the adsorption-and-desorption treatment tank 4.
또한 상기 흡탈착처리조(4)는 탈착시의 열손실을 최소화하기 위하여 보온재(45)로서 외벽에 설치구성되어지도록 한다.In addition, the adsorption-desorption treatment tank 4 is to be installed on the outer wall as a heat insulating material 45 to minimize the heat loss during the desorption.
도 5에 도시된 바와 같이 상기 흡탈착처리조(4)의 하부 또는 측부에 설치되는 분해반응조(5)는 상기 흡탈착처리조(4)의 가열봉(412)에서 발생되는 열화에 의해 탈착되며 일정시간이 경과된 후 퍼지팬(6)을 통해 배출로(52)로 유입된 퍼지가스 또는 공기에 의해 흡착제(411)에서 탈착된 오염물질이 함유된 공기를 유입로(51)로 이동시키게 되며 , 상기 유입로(51)로 유입된 오염물질이 함유된 공기는 분해반응조(5)에 일정시간동안 머무르면서 자외선램프(7)에서 발생되는 자외선에 의해 격판(53)에 도포된 광촉매와 산화반응이 일어나 분해 및 제거되도록 구성하였다.As illustrated in FIG. 5, the decomposition reaction tank 5 installed at the lower part or the side of the adsorption and desorption treatment tank 4 is desorbed by deterioration generated by the heating rod 412 of the adsorption and desorption treatment tank 4. After a certain time elapses, air containing contaminants desorbed from the adsorbent 411 by the purge gas or air introduced into the discharge path 52 through the purge fan 6 is moved to the inlet path 51. The air containing the contaminants introduced into the inlet passage 51 stays in the decomposition reaction tank 5 for a predetermined time and the photocatalyst and the oxidation reaction applied to the diaphragm 53 by the ultraviolet rays generated from the ultraviolet lamp 7 It was configured to get up and decompose and remove.
이때, 상기 격벽(53)에 사용되는 광촉매는 이산화티탄(TiO2)을 사용하는 것이 바람직하다.In this case, the photocatalyst used in the partition 53 is preferably titanium dioxide (TiO 2 ).
이와 같은 탈착온도를 감안할 때 내부공기의 연속순환은 열효율 측면에서 불리할 뿐만 아니라 광촉매에 의한 산화반응이 적당한 체류시간을 두어야 하고 폭발한계가 낮은 케톤류 등의 인화성 오염물질의 제거시에는 흡착제충진부(41)에 사용된 활성탄의 발화위험성으로 인하여 이를 방지하기 위한 질소가스 퍼지에도 다량의 가스가 소비되어 적당치 못하고, 상기 분해반응조(5)의 온도를 70~90℃ 이내로 유지하는 것이 광촉매반응에 있어 효율적임을 감안할 때, 또 다른 냉각수단이 필요하고 냉각으로 인하여 그만큼의 추가적인 열손실이 발생하므로 적당하지 않으므로, 본 고안에서는 이와 같은 문제점을 해결하기 위하여 주기적으로 퍼지시키는 방법을 이용하였는데 예로 5분마다 30∼50초 동안 퍼지하는 방법을 이용하여 가장 효과적인 분해반응을 이룰 수 있었다.In view of such desorption temperature, the continuous circulation of internal air is not only disadvantageous in terms of thermal efficiency, but also the oxidation reaction by photocatalyst should give proper residence time and the removal of flammable contaminants such as ketones with low explosion limit Due to the risk of ignition of activated carbon used in 41), a large amount of gas is consumed even to purge nitrogen gas to prevent this, and maintaining the temperature of the decomposition reaction tank 5 within 70-90 ° C. in the photocatalytic reaction. Considering the efficiency, it is not suitable because another cooling means is required and additional heat loss occurs due to cooling, so the present invention uses a method of periodically purging to solve such a problem. The most effective decomposition reaction is achieved by purging for ~ 50 seconds. Could.
위와 같이 가열수단인 가열봉(412)에 소비되는 전력량은 200~260℃ 탈착의 경우를 기준으로 연속순환 방법에 비하여 40~90% 이내로 감소하였고, 동일조건의 반응에 의한 분해시간 역시 연속순환 시 24시간 이상에서 12~8시간 정도로 2~3배 이상 증가하였다.As described above, the amount of power consumed by the heating rod 412, which is a heating means, was reduced to within 40 to 90% compared to the continuous circulation method based on the case of 200 to 260 ° C desorption. It increased more than 2-3 times from 24 hours to 12 to 8 hours.
한편, 상기 흡탈착처리조(4)에 층구조로 충진되어 사용하는 흡착제충진부(41)는 대기오염물질의 종류에 따라 선정될 수 있으며, 본 고안에서의 흡착제충진부(41)에 사용되는 흡착제(411)는 가장 일반적으로 널리 사용되는 활성탄과 제올라이트로 활성탄을 합성하여 구성된 흡착제 2가지를 이용하였는데 비교적 분자크기가 4~6Å이상 이거나 비극성으로 물에 용해도가 낮은 오염물질의 처리에는 저가의 활성탄을 사용하고 약 110∼160℃로 탈착하여 재생하는 것이 바람직하며, 4∼6Å 이하의 저분자나 극성물질의 처리에는 고가이지만 제올라이트 합성 흡착제를 사용하고 200∼260℃에서 탈착, 재생하는 것이 용이하다.On the other hand, the adsorbent filling unit 41 is used to fill the adsorption and desorption treatment tank 4 in a layered structure can be selected according to the type of air pollutant, used in the adsorbent filling unit 41 in the present invention The adsorbent 411 is composed of two types of adsorbents, which are synthesized from the most commonly used activated carbons and zeolites. It is preferable to regenerate by desorption at about 110 to 160 ° C., and it is expensive to process low molecules or polar substances of 4 to 6 kPa or less, but it is easy to desorb and regenerate at 200 to 260 ° C. using a zeolite synthetic adsorbent.
도 6과 도 7에 도시된 바와 같이 상기 반응분해조(5)는 소정거리를 이격하여 서로 대향되는 내벽면을 따라 다수개의 고정클램프(532)가 고정설치되고 상기 고정클램프(532) 상부에 복수개의 L형클램프(531)를 순환공(533)이 형성되도록 고정설치하여, 중앙부에 램프설치공(534)이 형성된 격판(53)을 상기 고정클램프(532)와 L형클램프(531)에 소정의 경사각을 갖도록 설치되어 이루어진다.As shown in FIGS. 6 and 7, the reaction cracking tank 5 has a plurality of fixing clamps 532 fixedly installed along inner wall surfaces facing each other with a predetermined distance therebetween, and a plurality of fixing clamps 532 are provided on the fixing clamp 532. Two L-type clamps 531 are fixedly installed so that the circulation hole 533 is formed, and the diaphragm 53 having the lamp installation hole 534 formed at the center thereof is fixed to the fixed clamp 532 and the L-type clamp 531. It is made to have a tilt angle of.
이와 같은 상기 분해반응기(5)는 오염물질을 포함하는 유해가스를 유입하는 것으로, 상기 분해반응기(5)의 광촉매 반응효율의 최적화를 위한 온도조절부(도면에 미도시)는 탈착시 온도에 의하여 광촉매 반응조의 온도가 80∼100℃ 이상이 되는 경우 설치하며, 상기 가스가 유,출입되는 유,출입구(51,52)가 외부면에 장착되고, 일정량의 물을 바닥에 채워 반응 중간에 생성된 수용성 물질을 용해시켜 별도로 설치된 중심파장 185nm이 오존발생 자외선램프(7)를 배치하여 수처리 방식으로 제거하도록 하며, 유입된 유해가스가 진행하며 냉각될 수 있도록 격벽(53)을 두며, 이를 통하여 충분한 냉각이 이루어지지 못하는 경우, 그 외부에 쿨링타워(Cooling tower) 또는 냉동기(Chiller)를 이용한 냉각이 이루어질 수 있는 장치를 더 설치할 수 있도록 구성되어진다.The decomposition reactor (5) is introduced into the harmful gas containing contaminants, the temperature control unit (not shown in the drawing) for the optimization of the photocatalytic reaction efficiency of the decomposition reactor (5) by desorption temperature It is installed when the temperature of the photocatalytic reaction tank is 80 to 100 ° C. or more, and oil and inlets 51 and 52 through which the gas flows in and out are mounted on the outer surface, and a predetermined amount of water is filled in the bottom to generate the reaction. Dissolve the water-soluble substance so that the central wavelength of 185nm installed separately is removed by the water treatment method by placing the ozone generating ultraviolet lamp (7), and the partition wall (53) is provided to allow the introduced harmful gas to proceed and cool. If this is not done, it is configured to further install a device that can be cooled by using a cooling tower (Cooling tower) or a chiller (Chiller).
