Description

소화가스 탈황 및 촉매 재생장치 {Desulpurization and catalyst regeneration apparatus}Desulpurization and catalyst regeneration apparatus

본 발명은 혐기성 소화조의 황화합물을 산화촉매에 의해 1,2차 반응시켜 탈황시키고 상기 1,2차 반응시에 사용된 탈황촉매를 재생하여 재활용할 수 있도록 하는 탈황 및 촉매장치를 집적시킨 구성으로 설치규모를 최소화하고 처리 효율성을 높일 수 있도록 한 소화가스 탈황 및 촉매 재생장치에 관한 것이다.
The present invention is installed in a configuration in which the sulfur compound of the anaerobic digestion tank is desulfurized by the first and second reactions by an oxidation catalyst, and the desulfurization and catalyst apparatus is integrated to regenerate and recycle the desulfurization catalyst used in the first and second reactions. The present invention relates to a flue gas desulfurization and catalyst regeneration apparatus that minimizes scale and increases processing efficiency.

일반적으로 사용되고 있는 혐기성 소화조내의 황 화합물을 제거하기 위한 탈황방법으로는 크게 건식 흡수법과 습식 흡수법으로 나뉘어진다.Desulfurization methods to remove sulfur compounds in the anaerobic digester which are generally used are divided into dry absorption method and wet absorption method.

상기 건식 흡수법은 산화철(Fe2O3), 활성탄 등과 같은 고체 흡착제와 접촉해서 황화합물을 제거하는 방식으로서 저온 및 저 습도에서 흡착성이 뛰어나지만 고농도의 물질을 처리할 겨우 발열이 심하게 일어나고 가스의 온도가 높은 겨우 흡착성능이 현저히 감소하며 습도가 높은 가스를 처리할 경우 수분에 의한 흡착 방해 또는 채널링(channeling)현상에 의해 흡착 효율이 급격히 저하된다.The dry absorption method removes sulfur compounds by contact with solid adsorbents such as iron oxide (Fe2O3) and activated carbon, and is excellent in adsorption at low temperatures and low humidity, but only generates excessive heat when processing high concentrations of substances and high gas temperatures. Adsorption performance is remarkably decreased, and when the gas is treated with high humidity, the adsorption efficiency is drastically lowered due to the blockage of adsorption by moisture or channeling.

습식 흡수법은 기체와 액체(흡수제)가 세정장치를 통해 향류 또는 병류로 접촉해서 황 화합물을 제거하는 기술로서 가성소다법과 액상산화법이 상용화 기술로서 존재한다. 가성소다법은 가장 오래된 기술로서 운전이 용이하고 성능이 뛰어나 과거에는 가장 보편화된 기술 중 하나였으나 사용 후 발생되는 폐가성소다의 처리비용이 고가이며 혐기성 소화조 내에 이산화탄소와의 반응 빼문에 과량의 가성소다가 소모되어 운전비용이 과다하고 과량의 강알칼리 페가성소다 발생으로 비환경친화적 기술로 분류되어 선진국에서는 기술보급이 중지되어 있다.In the wet absorption method, a gas and a liquid (absorbent) come into contact with each other in countercurrent or cocurrent flow through a washing apparatus to remove sulfur compounds, and a caustic soda method and a liquid oxidation method exist as commercialization technologies. Caustic soda method is the oldest technology, and it is one of the most popular technologies in the past because it is easy to operate and has excellent performance. However, the cost of disposal of spent caustic soda after use is high and the excess of caustic soda Due to the excessive operation cost and excessive alkali alkali pegasic soda generation, it is classified as an unfriendly environment, and the supply of technology is stopped in the developed countries.

따라서, 혐기성 소화조내의 황화합물을 환경친화적으로 제거하고 제거효율을 높일 수 있는 탈황수단이 요구되고 있으며, 또한 황화합물을 제거하기 위한 탈황비용이 상당하여 사업화하는데 있어 장애가 되고 있는 실정이다.Therefore, there is a need for a desulfurization means that can environmentally remove sulfur compounds in the anaerobic digester and increase the removal efficiency, and the desulfurization cost for removing sulfur compounds is considerable, which hinders commercialization.

이를 감안하여 본 발명자에 의하여 특허 제10-0762715호로 개시된 소화가스 탈황방법 및 장치와 그 촉매재생방법 및 장치에 의해 액상산화반응촉매를 활용하여 혐기성 소화조 내의 황화합물을 효율적으로 제거할 수 있도록 함과 상기 탈황에 사용된 산화촉매를 연속적으로 재생시켜 촉매소모량을 감소시킬 수 있도록 하였는바, 본 발명은 상기의 기술내용을 기반으로 하면서 설치규모를 최소화하고 처리 효율성을 높일 수 있도록 한 것이다.
