摘要

石灰石／石膏湿法脱硫装置的强制氧化系统是脱硫装置的关键系统，其氧化效果不仅影响到　石膏纯度及脱水机的安全运行，严重时甚至将不合格的石膏浆液排至灰场。在重庆发电厂烟　气脱硫装置的调试和试运行过程中，曾多次出现由于设计缺陷而造成的氧化效果不佳问题，　严重影响了脱硫装置的正常调试及运行。通过对氧化效果影响因素的分析，提出了相应的改　进措施，并以试验数据证明了这些措施的合理性和正确性。改进后的运行情况表明，氧化能　力明显改善。

Abstract

The forced oxidation system of lime stone/gypsum wet FGD equipment is an importa nt system of the said FGD equipment. The insufficient oxidation effectiveness of said system not only produces impact to the purity of gypsum and safe operation of the dewater

but also discharges gypsum slurry being not up to standard into the ash pond in serious situation. During the course of debugging and trial operation of the FGD system at Chongqing Power Plant

problems of not good oxidation effectiveness had many times occurred due to defects in the design

influencing seriously the normal debugging and operation of the FGD system. Through analysis of factors producing impact to the oxidation effectiveness

corresponding improvement measures have been put forward and having proved the reasonableness and correctness of the said measures by the test data obtained. The operation performance after improvement shows the oxidation capability has obviouly been enhanced.
