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)를 전기로내에 혼입하되, 상기의 특수탄소가루를 전기로의 저면에 얇고 고르게 깔고 그위에 상기의 칼슘원료(4)를 소정두께만큼 고르게 펴서 깐후, 다시 그위에 상기의 특수탄소가루를 부어서 상기의 칼슘원료가 보이지 않도록 하며, 상기의 방법을 반복하여 다수개의 층을 이루도록 혼입하는 과정(C)과, 상기의 전기로에 전원을 투입하여 로내의 온도가 2500℃~3000℃에서 20분내지 30분동안 칼슘원료를 소성시키는 고온소성과정(D)과, 상기에서 소성된 칼슘원료(4)를 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) of washing the calcium raw material (4) with sea water, and activated special carbon powder (5) prepared using charcoal powder and the calcium raw material (4) washed in the sea water are mixed in an electric furnace, Spread the special carbon powder thinly and evenly on the bottom of the electric furnace and spread the calcium raw material 4 evenly over a predetermined thickness thereon, and then pour the special carbon powder thereon so that the calcium raw material is not visible. Repeating the method of mixing to form a plurality of layers (C) and the high-temperature firing process for firing the calcium raw material for 20 to 30 minutes at 2500 ℃ ~ 3000 ℃ by turning on the power to the electric furnace (D), the step of cooling the calcined calcium raw material (4) above, and the step of grinding the calcined cooled calcium raw material (4) with a grinder (F) of the powdered calcium The property is more than 95% of calcium (CaO) content , Calcium oxide (CaO), characterized in that to manufacture such that the PH is less than 12.00 ~ 12.5 of the sap hydrated calcium relates to a method of manufacturing the same.
