| description | The utility model relates to the technical field of calcium and magnesium concentrated solution processing systems, in particular to a system for preparing magnesium nitrate and gypsum by using a calcium and magnesium concentrated solution. The utility model discloses a system for preparing magnesium nitrate and gypsum by using a calcium-magnesium concentrated solution. The system comprises a neutralization kettle, a first filter, a decalcification kettle, a second filter and a concentration crystallization kettle which are connected through pipelines, the neutralization kettle is used for carrying out neutralization reaction on the calcium-magnesium concentrated solution and crude magnesium oxide; the first filter is used for filtering a neutralization material liquid of a neutralization reaction; the decalcification kettle is used for first filtrate filtered by the first filter and a magnesium sulfate solution; and the second filter is used for filtering the decalcified liquid after the decalcification trea |
