System and method for preparing calcium oxide and sulfur by utilizing industrial byproduct gypsum
The invention provides a system for preparing calcium oxide and sulfur by using industrial by-product gypsum. The system comprises a feeding unit, a reaction unit and a discharging unit, wherein the feeding unit comprises a solid feeding unit and a gas feeding unit which are independently connected with a feeding hole of the reaction unit respectively, and the discharging unit comprises a calciumoxide discharging unit and a sulfur discharging unit which are connected with a discharging hole of the reaction unit respectively. The core process of the system provided by the invention is as follows: superheated steam reacts with industrial by-product gypsum to obtain calcium oxide, hydrogen sulfide and sulfur dioxide; hydrogen sulfide and sulfur dioxide further react to generate sulfur, the prepared sulfur can be directly used as a raw material for preparing acid from sulfur, calcium oxide is filtered to obtain an active calcium oxide product, and resource utilization of industrial by-product gypsum is realized.
本发明提供了一种利用工业副产物石膏制备氧化钙和硫磺的系统，所述的系统包括进料单元、反应单元和出料单元；所述的进料单元包括分别独立连接反应单元进料口的固体进料单元和气体进料单元，所述的出料单元包括分别连接反应单元出料口的氧化钙出料单元和硫磺出料单元。本发明提供的系统的核心工艺是过热水蒸气与工业副产物石膏反应获得氧化钙、硫化氢和二氧化硫，硫化氢和二氧化硫再进一步反应生成硫磺，制备得到的硫磺可以直接作为硫磺制酸的原料使用，氧化钙经过滤后获得具有活性的氧化钙产品，实现了工业副产物石膏的资源化利用。
