Abstract
본 발명은 칼슘성분이 많이 함유된 패각등의 칼슘원료를 소생시켜서 산화칼슘을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing calcium oxide by revitalizing calcium raw materials such as shells containing a large amount of calcium components.
칼슘원료(4)를 바닷물로 세척하는 세척과정(B)과, 숯가루를 이용하여 제조된 활성화된 특수탄소가루(5)와 상기의 바닷물에 세척된 칼슘원료(4) 및 코크스를 전기로내에 혼입하는 과정(C)과, 상기의 전기로의 저면에서 바람을 주입시킬 수 있도록 형성된 풍로(9)에서 바람을 주입하여 코크스를 가열시키고, 전기로에 전원을 투입하여 단시간에 로내의 온도를 2500℃ 내지 3000℃로 하여 고온소성시키는 과정(D)과, 상기에서 소성된 칼슘원료를 냉각시키는 과정(E)과, 상기의 소성냉각된 칼슘원료(4)를 분쇄기로 분쇄하는 과정(F)으로 제조된 분말상태의 칼슘의 속성이 칼슘(CaO) 함유율 95% 이상이고, 수화한 칼슘수액의 PH가 12.00~12.5 이내가 되도록 제조하는 것을 특징으로 하는 칼슘(CaO) 제조방법에 관한 것이다.The washing process (B) for washing the calcium raw material (4) with sea water, and the activated special carbon powder (5) prepared using charcoal powder and the calcium raw material (4) and coke washed in the sea water are mixed in the electric furnace. In the process (C) and the wind path 9 formed to inject the wind from the bottom of the electric furnace to heat the coke, and to turn on the electric furnace in a short time the temperature in the furnace 2500 ℃ to 3000 Powder prepared by the step (D) of high temperature firing at ℃, the step (E) of cooling the calcined calcium raw material, and the step of grinding the calcined cooled calcium raw material (4) with a grinder (F). Calcium (CaO) content of the state of the calcium (CaO) content of more than 95%, hydrated calcium sap to a calcium (CaO) manufacturing method characterized in that it is produced so that within 12.00 ~ 12.5.
