摘要

石灰石-石膏湿法脱硫工艺是目前应用最广的一种脱硫技术。随着国家环保考核力度的逐步加大

如何确保脱硫系统的安全运行

提高湿法脱硫系统的投运率已成为各电厂关注的焦点

而由于GGH堵塞、除雾器堵塞、吸收塔浆液起泡引起浆液大量溢流

脱硫系统辅机选型存在问题

石膏二级脱水系统异常等问题对脱硫系统的运行产生了很大的影响。本文结合豫新发电有限责任公司300MW机组脱硫装置的实际运行经验

分析了影响脱硫系统安全运行的的主要因素

并提出如何在确保安全运行的基础上做到经济运行。

Abstract

The limestone/gypsum wet desulfurization process is one of the most widely used desulfurization technology.As the national environmental assessment inspection gradually stepped up

how to ensure the safe operation of the desulfurization system and improve the rate of wet desulphurization system has become the focus of all the power plants.The problems such as GGH blocked

dimister blocked and the absorber slurry bubble caused slurry overflow

desulfurization system auxiliary selection problems

abnormalities of gypsum second-level dehydration system had a great impact to the desulfurization operation of the system.According to actual operating experience of 300 MW desulphurizing installations of Yuxin power generation Co.

LTD.

the main factors of the safe operation of desulfurization system were analyzed

and the economic operation manners based on safe operation were introduced.
