본 발명은 스테인레스강판, 선재, 강대 및 일반강의 강대등의 세척시 사용하는 질산에서 발생하는 질소산화물(NOx) 흡수 제거 방법에 관한 것으로, 보다 상세하게는 황화나트륨(Na2S)을 이용하여 질소산화물을 흡수제거하는 방법에 관한 것이다.The present invention relates to a method for removing nitrogen oxide (NO x ) absorption from nitric acid used in cleaning stainless steel sheets, wire rods, steel strips and steel strips, and more specifically, using sodium sulfide (Na 2 S). A method for absorbing and removing nitrogen oxides.
질소산화물은 일반적으로 금속 표면처리 공정 및 연소 설비, 질산 제조 설비 등에서 발생하는 가스로서 노란색의 질화물이다. 이 질소산화물은 인체내에서 산소와 결합하여 호흡 장애 및 중독 현상을 일으키고, 식물을 고사시키며, 산화성 물질과 결합하여 설비를 부식시키며, 스모그(Somg) 현상을 일으키는 등 유동성 기체로서, 환경 보전법에서는 배출 농도를 200ppm 이하로 제한하고 있다.Nitrogen oxide is a yellow nitride which is generally generated in metal surface treatment process, combustion equipment, nitric acid production equipment, etc. This nitrogen oxide is a fluid gas that combines with oxygen in the human body to cause respiratory disorders and poisoning, kills plants, corrodes the plant by combining with oxidizing substances, and causes smog. The concentration is limited to 200 ppm or less.
이러한 질소산화물의 제거 방법으로는 습식법과 건식법이 있으며, 건식법은 연소 설비등에서 사용하고 습식법은 대형 설비등에서 사용한다. 또한 금속 표면 처리 공정에서는 일반적으로 과망간산칼리법과 오존산화법, CℓO2법 등이 널리 사용되고 있다.The nitrogen oxide removal method includes a wet method and a dry method. The dry method is used in a combustion facility, and the wet method is used in a large facility. In addition, in the metal surface treatment process, the calcareous permanganate method, the ozone oxidation method, and the ClO 2 method are generally used.
그러나, 이러한 종래 기술에 있어서는 질소산화물이 효과적으로 제거되지 않으며, 슬러지(Sludge)가 발생하여 세정기 내부가 막히는 현상이 종종 발생하였다.However, in such a prior art, nitrogen oxides are not effectively removed, and sludge occurs, and the inside of the scrubber is often clogged.
특히, 과망간산칼리법을 이용하는 경우 슬러지가 고착되어 세정기 내부의 필터가 막혀 조업의 장애가 발생하는등 문제가 심각하였다.In particular, in the case of using the permanganic acid method, the sludge is stuck and the filter inside the scrubber is clogged, causing problems of operation.
본 발명은 상세한 종래 기술의 문제점을 해결하기 위하여 이루어진 것으로, 슬러지 생성을 방지할 수 있으며 질소산화물의 흡수제거율이 향상된 황화나트륨을 이용한 질소산화물의 흡수제거 방법을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the problems of the prior art, it is an object of the present invention to provide a method for removing the absorption of nitrogen oxides using sodium sulfide can prevent sludge generation and improved absorption rate of nitrogen oxides.
상기 목적을 달성하기 위하여 본 발명에서는, 황화나트륨(Na2S)을 5∼12%의 농도로 물에 희석하여 만든 용액을 질소산화물(NOx)과 접촉시킴으로써 질소산화물을 흡수제거하는 것을 특징으로 하는 질소산화물 흡수제거 방법을 제공한다.In order to achieve the above object, in the present invention, a solution made by diluting sodium sulfide (Na 2 S) in water at a concentration of 5 to 12% is contacted with nitrogen oxides (NO x ) to absorb and remove nitrogen oxides. It provides a nitrogen oxide absorption removal method.
이하에서는 본 발명을 실시예를 통해 상세히 설명한다.Hereinafter, the present invention will be described in detail through examples.
도 1에는 본 발명을 실시하는데 사용되는 질소산화물 세정기가 개략적으로 도시되고 있는데, 가스 입구(5)를 통하여 가스가 세정기 내부로 유입되면, 세정기 내부의 세정액(3)을 모터펌프(4)를 이용하여 노즐(1)로 공급하고 노즐(1)에서 세정액(3)을 분사하여 올라오는 가스를 세정하고 필터(2)에서 흡수제거하도록 구성되어 있다. 질소산화물이 흡수제거된 가스는 가스 출구(6)를 통해 외부로 배출된다.1 schematically shows a nitrogen oxide scrubber used to practice the present invention. When a gas flows into the scrubber through the gas inlet 5, the scrubbing liquid 3 inside the scrubber is used using a motor pump 4. It is configured to supply to the nozzle 1, spray the cleaning liquid 3 from the nozzle 1 to clean the gas coming up, and absorb and remove it from the filter 2. The gas from which nitrogen oxide has been desorbed is discharged to the outside through the gas outlet 6.
본 발명의 질소산화물 흡수제거 방법은, 황화나트륨(Na2S)을 5∼12%의 농도로 물에 희석하여 만든 용액을 질소산화물(NOx)과 접촉시킴으로써 질소산화물을 흡수제거하는 것을 특징으로 하는 구성이다.The nitrogen oxide absorption removal method of the present invention is characterized by absorbing and removing nitrogen oxides by contacting a solution made by diluting sodium sulfide (Na 2 S) in water at a concentration of 5 to 12% with nitrogen oxides (NO x ). It is a constitution.
본 발명에서 황화나트륨(Na2S)을 5∼12%의 한정한 것은, 질소산화물(NOx)의 규제치가 200 ppm인데, 5% 보다 작은 경우 가스중에 함유된 질소산화물이 규제치를 초과(예컨대, 4% 농도의 경우 201 ppm)하며, 12% 보다 큰 농도로 첨가하는 경우에는 첨가량의 증가에 비해 질소산화물의 흡수제거 효율의 증가 정도가 미미하여 비경제적인 점을 고려하여 상기 범위내로 한정한 것이다.In the present invention, 5 to 12% of sodium sulfide (Na 2 S) is limited, and the limit of nitrogen oxides (NO x ) is 200 ppm, but when it is less than 5%, the nitrogen oxide contained in the gas exceeds the limit (for example, , 4% concentration of 201 ppm), and when added at a concentration of more than 12%, the increase in the absorption efficiency of nitrogen oxides is insignificant compared to the increase in the amount of addition, and is limited to the above range in consideration of economical point.
도 2는 본 발명 방법에 따라 황화나트륨을 물로 희석한 용액을 세정액으로 이용하여 질소산화물을 흡수제거한 실시예를 그래프로 도시하고, 도 3에서는 황화나트륨 외에 가성소다(NaOH)를 더 함유시킨 용액을 세정액으로 사용한 경우의 질소산화물 제거예를 그래프로 나타내고 있는데, 우선, 가성소다와 질소산화물의 반응식은 다음과 같다.FIG. 2 is a graph illustrating an example in which nitrogen oxide is absorbed and removed using a solution of sodium sulfide diluted with water according to the present invention as a washing liquid, and in FIG. 3, a solution further containing caustic soda (NaOH) in addition to sodium sulfide is shown in FIG. Although the removal example of nitrogen oxide when using it as a washing | cleaning liquid is shown on the graph, First, the reaction formula of caustic soda and nitrogen oxide is as follows.
2NaOH + 2NO2→ NaNO3+ NaNO2+ H2O …… (1) 2 NaOH + 2NO 2 → NaNO 3 + NaNO 2 + H 2 O... … (One)
(1)의 반응에서 질산염과 아질산염이 생성되고, NO2와 NO는 다음 반응에 의해 아질산염을 생성한다.In the reaction of (1), nitrate and nitrite are produced, and NO 2 and NO form nitrite by the following reaction.
2NaOH + NO2+ NO → 2NaNO3+ H2O …… (2)2NaOH + NO 2 + NO → 2NaNO 3 + H 2 O... … (2)
과망간산칼리를 이용할 때는 과망간산칼리가 중성에 가깝고 가성소다는 강알칼리이고 생성물이 산성이기 때문에 가성소다를 중화용으로 사용하는데, 가성소다만으로는 질소산화물이 제거되지 않고 잔존하였다.When using permanganate, caustic soda is used for neutralization, because caustic permanganate is nearly neutral, caustic soda is strong alkali, and the product is acidic. Caustic soda alone does not remove nitrogen oxides.
참고로, 과망간산칼리를 이용한 질소산화물 제거 방법은 다음과 같다.For reference, a method for removing nitrogen oxide using a caloric permanganate is as follows.
KMnO4+ NO → KNO3+ MnO2↓ …… (3)KMnO 4 + NO → KNO 3 + MnO 2 ↓... … (3)
그러나, 이 방법에서는 (과망간산칼리+가성소다)에 의해 슬러지를 생성하므로 문제가 발생하여 효과적이지 못하다.However, in this method, sludge is produced by (caliper permanganate + caustic soda), which causes problems and is not effective.
따라서 본 발명에서는 황화나트륨(Na2S)을 사용하였다.Therefore, sodium sulfide (Na 2 S) was used in the present invention.
이러한 본 발명 방법에 따라 황화나트륨을 물로 희석하여 세정액으로 이용한 결과 질소산화물이 제거된 실시예를 도 2에 그래프로 나타냈는데, 질소산화물과 황화나트륨의 반응은 다음과 같다.Sodium sulfide was diluted with water according to the method of the present invention and used as a cleaning solution. An example in which nitrogen oxide was removed is shown in a graph in FIG. 2. The reaction between nitrogen oxide and sodium sulfide is as follows.
Na2S + 2NO2→ Na2SO3+ N2+ ½O2…… (4)Na 2 S + 2NO 2 → Na 2 SO 3 + N 2 + 1 / 2O 2 ... … (4)
도 2에 나타낸 바와 같이, 본 발명 범위로 황화나트륨을 첨가한 경우 질소 산화물이 급격히 감소되었는데, 6% 첨가시 질소산화물의 잔존량은 178ppm으로 흡수제거율이 84.16%이었으며, 9% 첨가시 질소산화물 잔존량은 155ppm으로 흡수제거율은 88.09% 이었으며, 12% 첨가시 질소산화물 잔존량이 145ppm으로 88.8% 이었다. 이에 대해, 황화나트륨 첨가량이 5% 보다 작은 4%의 경우 질소산화물의 잔존량이 201ppm, 2%의 경우 잔존량이 248ppm으로 규제치를 초과하였으며, 흡수제거 효율도 각각 81.21%, 76.82%로 낮았다.As shown in Figure 2, when the sodium sulfide was added to the scope of the present invention, the nitrogen oxide was sharply reduced, the residual amount of nitrogen oxide when the 6% addition was 178ppm, the absorption removal rate was 84.16%, the remaining nitrogen oxide when 9% added Absorption removal rate was 88.09%, and the residual amount of nitrogen oxides was 145ppm (88.8%) at 155ppm. On the other hand, in the case of 4% of the sodium sulfide addition amount less than 5%, the residual amount of nitrogen oxide was 201ppm, and in the case of 2%, the residual amount exceeded the regulation value of 248ppm, and the absorption removal efficiency was low as 81.21% and 76.82%, respectively.
이에 대해 질소산화물 1300ppm에 가성소다 20%를 첨가하고 황화나트륨을 각각 2%, 6%, 9%, 12% 첨가하여 질소산화물을 제거한 경우의 예를 도 3에 나타내었는데, 잔존 질소산화물의 양이 각각 280ppm, 197ppm, 182ppm, 172ppm이었으며, 흡수제거율이 각각 78.5%, 84.8%, 86%, 86.7%로 황화나트륨을 첨가하여 세정액을 만든 경우에 비해 잔존 질소산화물의 양이 많았으며, 흡수제거율도 낮았다.3 shows an example in which 20% caustic soda is added to 1300 ppm of nitrogen oxide and 2%, 6%, 9%, and 12% of sodium sulfide is removed to remove nitrogen oxides. 280ppm, 197ppm, 182ppm, and 172ppm, respectively, and the absorption removal rate was 78.5%, 84.8%, 86%, and 86.7%, respectively. .
상기 설명한 바와 같은 본 발명예와 비교예의 실험들은 질소산화물의 흡입가스량이 1300ppm으로 한 번에 3회 이상 실험하여 평균치를 취하였는데, 도 2 및 도3으로부터 알 수 있는 바와 같은 본 발명 범위 내로 황화나트륨을 첨가한 경우가 가장 질소산화물 흡수제거율이 양호하며 잔존 질소산화물의 양이 작았다.Experiments of the present invention and the comparative examples as described above were taken at an average value by experimenting three times or more at a time intake gas amount of nitrogen oxide 1300ppm, sodium sulfide within the scope of the invention as can be seen from Figures 2 and 3 In the case of the addition of nitrogen oxides, the removal efficiency of nitrogen oxide was the best and the amount of remaining nitrogen oxide was small.
상기 설명한 바와 같이, 본 발명의 황화나트륨을 이용한 질소산화물 흡수제거 방법에 의하면, 슬러지의 생성이 없으므로 필터가 막혀 세정기의 작동이 불량하게 되는 일이 없으며, 질소산화물의 흡수제거 효율이 향상되고 잔존 질소산화물의 양이 크게 저하되어 환경 공해를 방지할 수 있는 등 유용한 효과가 얻어진다.As described above, according to the nitrogen oxide absorption removal method using sodium sulfide of the present invention, since there is no sludge production, the filter is not clogged and the operation of the scrubber is not poor, and the absorption efficiency of nitrogen oxide is improved and the remaining nitrogen is improved. Useful effects are obtained such that the amount of oxide is greatly lowered to prevent environmental pollution.
