石灰石活性测试方法及其分析系统
摘要：
本发明公开一种石灰石活性测试方法及其分析系统，是将石灰石浆液同SO2烟气直接反应，模拟实际脱硫过程，通过测量SO2的脱除率来反映石灰石的活性，SO2脱除率越高，说明石灰石活性越好；SO2脱除率越低，说明石灰石活性越差。其分析系统主要包括石灰石浆液池、浆液泵、吸收塔、气体钢瓶、气体流量控制器、石灰石浆液回收池和浆液流量控制器。本发明综合考虑石灰石的成分、结构等方面性质对SO2吸收的影响；真实反应了石灰石的活性；不仅有利于在WFGD系统设计阶段选择合适的吸收剂，而且可以在运行阶段确定最优运行操作参数，进而降低投资与运行；测定方法简单、有效，易于实现，可以正确评价石灰石的活性，为烟气脱硫工程设计提供理论依据。
摘要（英）：

The invention discloses a limestone activity testing method and the analysis system thereof, making limestone pulp directly react with SO2 fume, simulating actual desulfation course, and reflecting limestone activity by measuring SO2 removal ratio, where the higher the SO2 removal ratio is, the better the limestone activity is and vice versa. And the analysis system mainly comprises limestone pulptank, pulp pump, absorption tower, gas steel cylinder, gas flow controller, limestone pump recover tank and pulp flow controller. And the invention can truly reflect limestone activity and reduce investment and operating cost. And the method is simple, effective and easy to implement, and able to accurately evaluate limestone activity and provides theoretical basis for fume desulfation engineering.
