基于近零排放的除尘器升级改造设计选型相关问题技术分析

Technical Analysis on Design and Selection in Precipitators Upgrade for Net Zero Emissions

目前燃煤电厂为了进一步降低烟囱排放的固体颗粒物浓度,进行了相关的除尘器升级改造,如在原有电除尘器基础上改造的技术组合及增加湿式电除尘器,但目前的除尘器升级改造后也出现了一些设计选型及运行方面的问题,本文针对这些问题进行了相关的技术分析及探讨。

At present,the coal-fired power plant is improving the ESP,with the purpose to reduce the density of par- ticulate matter. The technology of ESP has been improved,and the WESP has been used. There were some problems with selection and operation when we were improving the ESP. In this paper,these problems will be analyzed and dis- cussed.
