| titleOfInvention | Method for quickly separating calcium and sulfur of industrial byproduct gypsum |
| abstract | The patent discloses a method for quickly separating calcium and sulfur from industrial byproduct gypsum, which is used for quickly decomposing the industrial byproduct gypsum to obtain sulfur dioxide flue gas and solid products; sorting the solid product to obtain an atmosphere regulator, calcium oxide and calcium sulfide; hydrolyzing calcium sulfide to obtain calcium hydroxide precipitate and calcium hydrosulfide solution; introducing carbon dioxide gas into the calcium hydrosulfide solution to obtain calcium carbonate precipitate and hydrogen sulfide gas; absorbing and floating hydrogen sulfide gas to obtain elemental sulfur. Compared with the prior art, the method has the characteristics of low production cost, high production efficiency and good product quality. |
