CN108744906A 一种磷矿浆湿法脱硫添加剂 无效 - 驳回

一种磷矿浆湿法脱硫添加剂
摘要：
本发明公开一种磷矿浆湿法脱硫添加剂，包括硝酸盐、金属氧化物、有机酸和盐类物质。所述添加剂能够减缓反应体系的pH值下降，提高磷矿的利用率，增加脱硫系统的稳定性，进而提高SO2的去除率。在一定时间内，添加剂加入到反应体系中处理工业烟气，反应120min后，磷矿浆脱硫系统的脱硫效率比不加添加剂条件下提高5‑20%，从而提高磷矿的利用率，达到资源化利用的目的。
摘要（英）：

The invention discloses a phosphoric ore pulp wet desulphurization additive. The phosphoric ore pulp wet desulphurization additive is prepared from nitrate, a metallic oxide, organic acid and a salt material. The additive can slow down decline of the pH value of a reaction system, improve the use rate of phosphoric ore, improve the stability of a desulphurization system and thus improve the removal rate of SO2; in certain time, the additive is added into the reaction system for industrial flue gas treatment, after reaction is carried out for 120 minutes, the desulphurization efficiency of thephosphoric ore pulp desulphurization system is improved by 5-20% compared with the desulphurization efficiency of the condition without adding the additive, thus the use rate of the phosphoric ore isimproved, and the purpose of recycling is achieved.
