| 摘 要： | 燃煤电厂建设前必须考虑满足环保部门的严格排放要求。本文介绍循环干式洗涤器烟气脱硫技术，该法以化工工艺中的流化床为工艺基础，以石灰为ＳＯ２吸收剂，用向烟气中喷入少量水陴低烟气温谋和提高ＳＯ２脱除率，用吸收剂循环提高石灰利用率。

| Abstract: | Construction can begin on a new coal -fired power plant,a rigorous set of permit requirements must be satisfied. Circulating dry scrubber (CDS)for flue gas desulfurization(FGD)is based on fluid bed absorption process. It uses dry lime to control SOz emission, minor water injection to lower the flue gas temperature,and circulating through the absorber to improve lime utilization.CDS absorber operates as a chemical reactor absorbing gaseous containments and as an evaporator. Compared with other FGD processes,CDS system is easy to control with no clogging taking place in pipelines and less mainte-nence cost. Therefore, it is economically attractive. |
