Description
본 발명은 SOx/NOx 동시처리 또는 단일성분 분리처리용 광촉매 박막형 광화학 반응 시스템에 관한 것으로서, 더 상세하게는 광촉매와 광에너지의 활용하여 두 산화물(SOx/NOx)을 동시 또는 단일성분 SOx와 NOx을 각각 별도로 처리할 수 있는 광화학 반응시스템의 개발에 관한 것이다.The present invention relates to a photocatalyst thin-film photochemical reaction system for simultaneous SOx / NOx treatment or single component separation treatment. More particularly, the present invention relates to two oxides (SOx / NOx) simultaneously or single component SOx and NOx using photocatalyst and light energy. The present invention relates to the development of a photochemical reaction system that can be treated separately.
과학이 급속도로 발전하면서 많은 에너지가 필요하게 되었으며, 이로 인한 에너지 수요량의 증가는 인체와 환경 및 자연에 덜 해로운 고급 연료의 사용에서 벗어나 값싼 저급연료의 사용을 확대시키는 계기가 되었으며, 저급 연료를 사용함에 따라 저급 연료에 다량 함유되어 있는 SOx/NOx와 같은 황/질소 산화물의 배출을 대기중에 배출시킴으로 인해 대기환경악화, 산성비 오존층의 파괴의 문제가 대두되는 원인이 되었다.The rapid development of science has required a lot of energy, and this increase in energy demand has led to the expansion of the use of cheaper low-end fuels, away from the use of advanced fuels that are less harmful to the human body, the environment and nature. As a result, emissions of sulfur / nitrogen oxides such as SOx / NOx contained in a large amount of lower fuels into the atmosphere have caused problems of deterioration of the atmospheric environment and destruction of the acid rain ozone layer.
현재는 주로 SOx는 습식 석회석 공정을 통해서, NOx는 선택적 촉매 환원법을 이용하여 처리하고 있으나, 각기 제거할 수 있는 대상이 제한되어 여러 물질들이 포함된 배기가스를 처리하기 위해서는 분리공정 등 여러 종류 단위의 유니트(unit)조합이 필요하여, 여러 종류의 유니트(unit)가 필요하더라도 그 유니트(unit)를 설치할 공간과, 설치할 당시의 투자비, 및 운전비용 면에서 막대한 비용이 투자가 되어야 함으로 경제적인 부담을 주는 원인이 되었다.Currently, SOx is mainly treated by wet limestone process and NOx is treated by selective catalytic reduction method. However, since it is limited to remove each object, various types of units such as separation process are needed to treat exhaust gas containing various substances. Unit combinations are required, so even if several types of units are required, the economic burden must be invested in the space for installing the units, the investment cost at the time of installation, and the huge cost in terms of operation costs. Lord was the cause.
즉 다시 말하면 고온/고압을 이용하였으며 운전조건이 까다로운 것은 물론 에너지 소모가 많고 2차처리 공정이 반드시 필요함으로 시스템 구성이 복잡하여 초기투자비용이 많이 들고 설치 면적이 넓어야만 설치가 가능한 것이다.In other words, high temperature / high pressure was used, and operating conditions were not only difficult, but also high energy consumption and a second treatment process were required. Therefore, the system configuration was complicated, so the initial investment cost was high and the installation area was large.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 광촉매와 광에너지의 활용하여 간단하면서도 두 산화물(SOx/NOx)을 동시 또는 단일성분 SOx와 NOx을 각각 별도로 처리할 수 있는 광화학 반응시스템의 개발하여 환경 개선의 일익을 담담하고자 하는데 그 목적이 있는 것이다.The present invention has been made in order to solve the above problems, a photochemical reaction system that can be treated by using a simple photocatalyst and light energy, but can simultaneously process two oxides (SOx / NOx) or single component SOx and NOx respectively. It aims to contribute to the improvement of the environment by developing it.
상기의 목적을 달성하기 위해 튜브 형태로 광촉매인 티타니아가 내측에 결합되고 상·하 끝단에 나사부가 형성된 반응기 몸체 상하 일측에 유입구와 배출구를 형성하고, 상기 튜브 형태의 반응기 몸체 내측에 램프를 삽입하고 고무 패킹을 램프에 끼우는 것과, 나사부가 일측에 부착되고 중앙에 홀이 형성된 마개를 반응기의 나사부에 마개의 나사부를 결합하여 일체형이 되게 결합하고 유입구와 배출구를 통해 오염 물질인 대기 가스를 반응기를 통과하게 하여 배기 가스의 황/질소 산화물질을 정화할 수 있는 것을 제공함에 있는 것이다.In order to achieve the above object, the photocatalyst titania is formed in the tube shape and the inlet and the outlet are formed on the upper and lower sides of the reactor body in which the upper and lower ends are threaded, and the lamp is inserted into the reactor body of the tube shape. The rubber packing is fitted to the lamp, and the screw part is attached to one side and the hole is formed at the center, and the screw part of the reactor is combined to be integral with the screw part of the reactor, and the contaminant atmospheric gas is passed through the reactor through the inlet and the outlet. In this regard, the sulfur / nitrogen oxides of the exhaust gas can be purified.

상기 반응기(16) 재질은 pyrex이며, 마개(10)는 중심부에 램프(20)를 위하여 램프(20)직경 만큼의 홀(18)이 있는 형태이다.The material of the reactor 16 is pyrex, and the stopper 10 has a hole 18 having a diameter corresponding to the diameter of the lamp 20 for the lamp 20 at the center thereof.
상기 램프(20)는 반응기(16)에 삽입 후 양끝을 마개(10) 중심부를 통과하게 한 후 막으면, 반응기(16) 중심부에 고정된 상태로 전원 공급 부분만이 도 1과 같이 반응기(16) 외부로 노출이 되게 된다.When the lamp 20 is inserted into the reactor 16 and both ends thereof pass through the center of the stopper 10 and then closed, only the power supply part is fixed to the center of the reactor 16 as shown in FIG. 1. ) Will be exposed to the outside.
전원은 홀(18) 통해 밖으로 돌출된 전극부를 통해 램프(20)는 점등이 될 수 있는 것이다.The power source is that the lamp 20 can be turned on through the electrode portion protruding out through the hole 18.
상기 마개(10)를 막기 전 고무 패킹(15)을 끼워 오염물질인 유체의 유출을 막았으며 램프(20)와 반응기(16) 내벽 사이를 오염물질인 유체가 이동할 수 있도록 간극(28)을 주었으며 이 간극(28)은 작을수록 좋은 것이다.Before the plug 10 was blocked, the rubber packing 15 was inserted to prevent the flow of contaminant fluid, and a gap 28 was provided to allow the contaminant fluid to move between the lamp 20 and the inner wall of the reactor 16. The smaller this gap 28 is, the better.
본 발명에서 사용된 반응기 내측에 삽입된 광촉매(26)는 티타니아(TiO2) 또는 혼합광촉매(니켈-티타니아, 철-티타니아, 몰리브데늄-티타니아, 나니오비움-티타니아, 실리카-티타니아 혼합촉매, 백금담지 티타니아 등)를 사용하였다.The photocatalyst 26 inserted into the reactor used in the present invention is a titania (TiO 2 ) or a mixed photocatalyst (nickel-titania, iron-titania, molybdenum-titania, naiodium-titania, silica-titania mixed catalyst, Platinum supported titania, etc.) was used.
또한 광에너지로는 UV램프(20)를 사용하였으며, 광에너지를 최대의 효율로 공급하기 위하여 튜브형 반응기(16) 내부에 내부코팅형(도 1 참조)으로 구성하였다.In addition, UV lamp 20 was used as the light energy, and the inner coating type (see FIG. 1) was configured inside the tubular reactor 16 to supply light energy with maximum efficiency.
상기 광촉매(26)의 코팅은 졸 상태에서 분사시키거나 슬러리 용액을 조성하여 분사시켜서 최적의 박막을 형성시켰다.The coating of the photocatalyst 26 was sprayed in a sol state or by spraying a slurry solution to form an optimum thin film.
상기 자외선 램프(20)를 튜브형 반응기(16) 내부에 삽입할 수 있도록 구성하고 유입구(22)와 배출구(24)를 통해 유입되고 배출되는 황/ 질소계를 빛 에너지가 박막으로 구성된 광촉매층(30)에 공급되도록 연결하였다.The UV lamp 20 is configured to be inserted into the tubular reactor 16 and the photocatalyst layer 30 composed of a thin film of light energy having sulfur / nitrogen introduced and discharged through the inlet 22 and the outlet 24. ) To be fed.
상기 광촉매층(30)을 통과한 배기 가스는 다시 질소 산화물 분석기(32)에서 질소 산화물을 분해하고, 질소 산화물이 분해된 배기 가스는 다시 황 산화물 분석기(34)에서 황 산화물을 분석한 후 벤트로 이동되어 대기중으로 빠져 나오게 되는 것이다.The exhaust gas passing through the photocatalyst layer 30 decomposes the nitrogen oxide in the nitrogen oxide analyzer 32 again, and the exhaust gas in which the nitrogen oxide is decomposed is analyzed again with the sulfur oxide analyzer 34 and then vented. It will be moved out of the atmosphere.
이러한 처리대상물질들에 대한 기존의 처리기술과 비교하여 보면, 본 기술과 시스템은 고온/고압을 이용하지 않아 운전조건이 수월하고, 에너지 소모가 적으며 2차처리 공정이 생략될 수 있기 때문에 시스템 구성이 단순화되어 초기투자비용이 절감되고 공장부지가 작아도 설치가 가능한 것이다.Compared with the existing treatment technology for these treatment materials, this technology and system does not use high temperature / high pressure, so it is easy to operate, low energy consumption, and the second treatment process can be omitted. Simplified construction reduces initial investment costs and enables installation even on small factory sites.
도 2에는 NO를 두 개의 초기 농도에서 분해 실험한 결과를 나타내었다.2 shows the results of decomposition experiments of NO at two initial concentrations.
산화제 첨가없이도 70 ∼ 98% 정도의 분해효율을 얻는 것을 알 수 있다.It can be seen that a decomposition efficiency of about 70 to 98% is obtained without adding an oxidizing agent.
도 3에서는 SO2와 NOx를 공기나 산소와 함께 동시에 주입하여 분해를 실시한 결과이다. 결과 그래프를 살펴보면 공기보다는 산소 주입시 분해율이 증가되었으나, 반응시간에 따라서는 정반대의 현상이 나타나는 것을 알 수 있는 것이다.In FIG. 3, SO 2 and NO x are simultaneously injected together with air or oxygen to decompose. Looking at the result graph, the decomposition rate was increased at the time of oxygen injection than air, but it can be seen that the opposite phenomenon occurs depending on the reaction time.
그러므로 본 발명은 60초 반응이 적절한 것으로 판단되었으며, 도 4에서는 NO반응의 확인 작업으로 FTIR분석 결과를 보여주고 있다.Therefore, in the present invention, it was determined that the 60 second response was appropriate, and FIG. 4 shows the results of the FTIR analysis as a confirmation operation of the NO response.
그러므로 본 발명은 배기가스의 두 산화물(SOx/NOx)을 동시 또는 단일성분 SOx와 NOx을 각각 별도로 처리할 수 있어 환경 개선의 일익을 담당할 수 있는 발명인 것이다.Therefore, the present invention can treat two oxides (SOx / NOx) of the exhaust gas simultaneously or separately in a single component SOx and NOx can be responsible for the improvement of the environment.
