摘要:

摘 要:在超净排放的半干法脱硫系统中,原有的布袋除尘器已经不能满足严格的排放要求,需要进行优化升级改造。介绍了布袋除尘器的气布比、上升气流速度、清灰系统、滤料、预沉降室、气流布风系统、旁路系统、控制系统、安装精度等各方面的优化措施,可为超净排放工程提供参考。

Abstract:

Abstract:For the semi dry flue gas desulfurization system in ultra clean emission engineering, the original bag filter could not satisfy the more strict emission requirement any more, which needs an optimal upgrading. This paper introduced the optimization measures on various aspects, such as the airtocloth ratio of bag filter, updraft velocity, dust cleaning system, filter materials, presettling chamber, airflow distributing system, bypass system, control system, and installation accuracy, etc., which provided a reference for ultraclean emission engineering.
