为提升除尘器除尘效率，达到环保烟气排放要求，镇海发电厂对4台燃煤机组烟气除尘器进行了改造，由单一的电除尘改造为电除尘作为前级，布袋除尘作为后级组成电袋复合除尘系统。经过改造之后，除尘效率由原先的99.3%～99.5%提升至99.9%，烟尘排放浓度由100 mg/m3以上降低到20 mg/m3以下，达到国家环保要求的排放标准，例举了运行中常见的缺陷及处理方法。
為提升除塵器除塵效率，達到環保煙氣排放要求，鎮海髮電廠對4檯燃煤機組煙氣除塵器進行瞭改造，由單一的電除塵改造為電除塵作為前級，佈袋除塵作為後級組成電袋複閤除塵繫統。經過改造之後，除塵效率由原先的99.3%～99.5%提升至99.9%，煙塵排放濃度由100 mg/m3以上降低到20 mg/m3以下，達到國傢環保要求的排放標準，例舉瞭運行中常見的缺陷及處理方法。

In order to improve the efficiency of dust precipitator to meet national gas emission requirement, gas precipitators of four coal-fired units in Zhenhai Power Plant are renovated: the dust precipitator is trans-formed from single dust precipitation to composite electric-bag dust precipitation system comprising an upper-level electric precipitation and a lower-level cloth bag precipitator. After renovation, the precipitation efficien-cy is raised from 99.3%~99.5%to 99.9%, and gas emission concentration is reduced from more than 100 mg/m3 to 20 mg/m3, which meets the emission standard of national environmental protection requirement. The paper also gives some examples of common defects and treatment methods.
