Abstract

냉각탑과 흡수탑으로 이루어진 탈황장치에서, 냉각탑(10)벽의 외부에 냉각수 공급배관(14)이 그리고 냉각탑 벽면에 스프레이 노즐(16)의 끝단(18)이 지그재그 형태로 설치되어 있으며, 흡수탑(12) 내부에 충진층(20)이 장치되어 있고 상부에는 엘리미네이트(22)가 설치되어 있으며 충진층에서 수산화마그네슘 슬러리와 폐가스가 접촉됨을 특징으로 하는 수산화마그네슘 슬러리를 이용한 탈황장치, 폐가스중의 아황산가스는 냉각탑(10)외벽에 설치된 냉각수 공급배관(14)과 연결된 스프레이 노즐(16)을 통해 스프레이 노즐의 끝단(18)에서 약 5m의 스프레이 입도 도달거리로 냉각수를 냉각탑의 내부에 공급하여 폐가스 유입구(24)를 통해 들어온 폐가스를 약 35-40℃의 온도까지 냉각하고, 흡수탑(12)에서 저액기비의 수산화마그네슘 슬러리 희석용액을 디스트리뷰터를 통해 분사하여 충진탑에서 흡수함.In the desulfurization apparatus consisting of a cooling tower and an absorption tower, a cooling water supply pipe 14 is disposed outside the wall of the cooling tower 10 and an end 18 of the spray nozzle 16 is installed in a zigzag form on the wall of the cooling tower. 12) Desulfurization apparatus using magnesium hydroxide slurry, characterized in that the magnesium hydroxide slurry and the waste gas in contact with the filling layer 20 is installed inside, and the laminate 22 is installed on the upper portion, the waste gas in the waste gas Sulfur dioxide gas is supplied through the spray nozzle 16 connected to the cooling water supply pipe 14 installed on the outer wall of the cooling tower 10 to the inside of the cooling tower at a spray particle size of about 5 m from the end 18 of the spray nozzle. The waste gas introduced through the inlet port 24 is cooled to a temperature of about 35-40 ° C., and the low liquid ratio magnesium hydroxide slurry dilution solution is removed from the absorption tower 12. By injection through absorbs in the packed column.
