Beschreibung
Zusammenfassung:	The invention provides a system for producing calcium sulfate from calcium carbide slag and waste sulfuric acid. The system comprises a reaction kettle, a reaction chamber and an elevated waste acid tank, wherein the reaction kettle is used for receiving the calcium carbide slag and clear water; the calcium carbide slag and the clear water form a calcium carbide slag emulsion with the solid content of 10-20% in the reaction kettle; the reaction chamber is fixed into the reaction kettle through a supporting component and provides a closed reaction room for the calcium carbide slag emulsion in the reaction kettle; the elevated waste acid tank is used for guiding the waste sulfuric acid into the calcium carbide slag emulsion through a sulfuric acid pipe so as to produce turbid calcium sulfateliquid after a reaction of the calcium carbide slag emulsion and the waste sulfuric acid. The system for producing the calcium sulfate from the calcium carbide slag and the waste sulfuric acid, provided by the invention, is
