【标题】脱硫石膏废浆液利用改造

【Title】Reform of utilizing waste slurry of gypsum

【摘要】本文针对大唐耒阳发电厂非正常工况下石膏废浆液排放的实际情况，制定了改造方案，设计了一种石膏废液利用系统；对石膏废浆液利用改造后的节能经济效益进行了估算；分析了改造后非正常工况下脱硫系统的运行情况；明确了石膏废液利用系统投运应注意的问题。结果表明：改造后系统运行正常，基本解决了＃1、2机组全停后脱硫废浆液排放的问题，提高了脱硫运行的经济性，达到了节能减排的目的。

【Abstract】in the actual situation of emission of waste slurry of Gypsum under abnormal conditions at Datang Leiyang power plant, reforming program  was Formulated in this paper; the system of utilizing waste slurry of Gypsum was designed; the energy-efficient and economical benefit was estimated after reform of utilizing waste slurry of gypsum; the operator situation of desulfurization system under abnormal conditions was analyzed after reform; the problems that should be noted in the commissioning process of system of utilizing waste slurry of gypsum were clearly put forward. The results show that system is running normally after reform, the problem of emission of waste slurry of Gypsum after units of NO.1 and NO.2 both  stop  running,  economical  character  of desulfurization operator is improved, and the target of energy conservation is reached.
