콜로이드형 습식 TiO2 반응기를 이용한 고효율 악취처리 장치 및 방법{High -efficiency odor treatment apparatus using coloid wet type Ti02 reactor and method thereof}TECHNICAL FIELD The present invention relates to a high-efficiency odor treatment apparatus using colloidal wet TiO2 reactor,

본 발명은 콜로이드형 습식 TiO2 반응기를 이용한 고효율 악취처리 장치 및 방법 관한 것으로서, 더욱 상세히는 하수처리장 및 악취 오염원에서 발생하는 악취를 복합처리할 수 있는 장치와 방법으로 기존의 TiO2 박막코팅 시스템에서 단점을 보완한 콜로이드 상태의 수용액 TiO2 광촉매를 이용하여 고효율로 악취를 처리할 수 있는 장치 및 방법에 관한 것이다.The present invention relates to an apparatus and a method for treating a high-efficiency odor using a colloidal-type wet TiO2 reactor, and more particularly, to an apparatus and a method for treating odors generated in a sewage treatment plant and a malodorous source, The present invention relates to an apparatus and a method for treating a malodor with high efficiency by using a supplemented colloidal aqueous solution TiO2 photocatalyst.

광촉매로서 사용되는 반도체는 가전자대(價電子端; Balance band), 전도대(傳導帶; Conduction band) 가 있고 그 에너지 준위의 차이를 밴드갭에너지(Bandgap energy)라고 한다. Semiconductors used as photocatalysts have a valance band and a conduction band, and the difference in energy level is called a bandgap energy.

이하 본 발명에 첨부된 도면을 참조하여 본 발명을 상세히 설명하기로 한다. 우선, 도면들 중, 동일한 구성요소 또는 부품들은 가능한 한 동일한 참조부호를 나타내고 있음에 유의하여야 한다. 본 발명을 설명함에 있어, 관련된 공지기능 혹은 구성에 대한 구체적인 설명은 본 발명의 요지를 모호하지 않게 하기 위하여 생략한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that, in the drawings, the same components or parts have the same reference numerals as much as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

본 명세서에서 사용되는 정도의 용어 약, 실질적으로 등은 언급된 의미에 고유한 제조 및 물질 허용오차가 제시될 때 그 수치에서 또는 그 수치에 근접한 의미로 사용되고, 본 발명의 이해를 돕기 위해 정확하거나 절대적인 수치가 언급된 개시 내용을 비양심적인 침해자가 부당하게 이용하는 것을 방지하기 위해 사용된다.As used herein, the terms "substantially", "substantially", and the like are used herein to refer to a value in or near the numerical value when presenting manufacturing and material tolerances inherent in the meanings mentioned, Absolute numbers are used to prevent unauthorized exploitation by unauthorized intruders of the mentioned disclosure.

본 발명에서는 악취 처리를 위해 TiO2 광촉매를 약 10nm 이하로 줄여 수용액 상태로 만들어 sol-gel 형태의 콜로이드상의 형태로 전환하였으며, 기존의 TiO2와 달리 박막 코팅이 아닌 콜로이드 상에서의 촉매반응을 하도록 유도하여 장점으로는 콜로이드상의 TiO2 입자에서 광산화·환원 반응이 입자 표면에서 동시에 일어나며 입자 하나를 미세한 광전기화학 셀로 볼 수 있다.In the present invention, the TiO2 photocatalyst is reduced to about 10 nm or less to convert it into an aqueous solution state and converted into a sol-gel type colloid-like form. In contrast to the conventional TiO2, , Photo-oxidation and reduction reactions occur simultaneously on the surface of the colloidal TiO2 particles, and one particle can be seen as a fine photo-electrochemical cell.

콜로이드상의 광촉매의 결정 입자 크기를 반경 약 10nm 이하로 줄이면 전하이동체(charge carrier)는 양자역학적으로 마치 상자 안에 갇힌 압자(particle-in-a-box)처럼 행동하게 되는 특이한 현상이 관찰된다.When the crystal size of the colloidal-phase photocatalyst is reduced to a radius of about 10 nm or less, the charge carrier is observed to behave like a particle-in-a-box in a quantum mechanical manner.

이런 양자 효과로 말미암아 밴드 간격이 증가하게 되고 band edge가 이동하여 보다 높은 산화 환원 전위를 형성하게 된다. 양자크기로 만들어진 콜로이드상의 광촉매는 광반응의 속도제한단계(rate limiting step)가 전하전이 반응일 경우 광효율(photo efficient)을 향상시킨다.This quantum effect increases the band gap and moves the band edge to form a higher redox potential. A colloidal-like photocatalyst made of quantum size improves photo efficiency when the rate limiting step of the photoreaction is a charge transfer reaction.

2차 반응기에서는 1차 반응기에서 제어하지 못한 미량의 악취 및 기타 대기오염물질을 제거하는 필터로 아이론 파우더 및 활성탄을 이용한 것을 특징으로 한다.The second reactor is characterized by using iron powder and activated carbon as a filter for removing a small amount of odor and other air pollutants that are not controlled in the first reactor.

1) TiO2 콜로이드 합성과정 (Synthetic process of TiO2 colloid)1) Synthetic process of TiO2 colloid

Ti(OBu)4와 acetylacetone (AcAc)를 1:4 몰 비율로 실온에서 잠시 동안 교반 한 후 1 부탄올 30ml를 용액을 추가 희석하고, 15분 동안 교반시킨 후 질산 수용액을 첨가하였다. 콜로이드 분산은 투명 졸에 60 ℃ 온도로 유지하여 하루동안 숙성시켰다.Ti (OBu) 4 and acetylacetone (AcAc) were stirred in a 1: 4 molar ratio at room temperature for a while, 30 ml of 1-butanol was further diluted, stirred for 15 minutes, and an aqueous nitric acid solution was added. The colloidal dispersion was kept in a transparent sol at a temperature of 60 캜 for aging for one day.

2) 콜로이드 TiO2 반응2) Colloidal TiO2 reaction

악취 물질을 1차 반응기에 1m/min 유속으로 유입시키며 이와 더불어 오존도 같은 유량으로 주입한다.The odorous substance is introduced into the first reactor at a flow rate of 1 m / min and the ozone is injected at the same flow rate.
