摘要
石灰石作为湿法脱硫的吸收剂,对烟气脱硫的过程和效果有着重要影响。对石灰石活性的研究不仅有利于火电厂选择合适的石灰石,而且对于优化工艺参数也具有重要意义。分别从石灰石的物理性质(CaCO3的含量、粒径、地质年代)及其所处的运行环境(浆液的PH值、浆液中所含离子、CO2浓度、温度、搅拌等)来分析影响石灰石活性的因素,指出了维持石灰石高活性时这些因素的典型设计范围,并根据我国国情提出了开展石灰石活性研究的建议。
As the absorbent for wet desulPHurization, limestone is of significance to the FGD process. The study on the reactivity of limestone is important not only to limestone selection for FGD on thermoelectric power stations, but also to the optimization of process parameters. In this paper, factors are analyzed, which have effects on the limestone activity, such as the PH ysical properties （content of CaCO3, size of granules, and geological years, etc.） of the limestone and the operation environment （PH of slurry, ions in the slurry, CO2 composition, temperature, and stirring, etc.）. Ranges of these factors for maintaining a high reactivity of limestone are suggested for design, and suggestions are made for carrying out limestone reactivity researches in China.
