袋式过滤器在苯菲尔脱碳溶液中的运用

摘要

采用NOMEX材质的四袋悬盖式过滤器对苯菲尔脱碳溶液过滤器进行改造，投用后效果明显，滤袋中滤饼较多，杂质颗粒细，有部分有机杂质吸附。溶液消泡时间缩短，溶液中铁离子的含量有明显的降低，系统腐蚀减轻，药品损耗减少，改善了脱碳系统运行状况，NOMEX材质过滤袋可重复使用。%A filter for Benfield decarbonization solution is retrofitted by using a filter with 4-bags and a hinged cover made of NOMEX and effect is obvious after putting into use.
