烟气脱硫脱硝技术存在的问题

发布人:华力能源设备发布日期:2017-11-07浏览量:372

烟气脱硫技术一木棋牌是目前被公认最有效的控制二氧化硫污染的技术。国外烟气脱硫技术起步于19世纪,经过一百多年的发展,已开发了上百种烟气脱硫技术。其中比较有代表性的技术有钙法、钠法、镁法等技术。这些烟气脱硫技术为发达国家二氧化硫污染的控制起到了重大作用,但仍是以高开采、高污染、高消耗、低效益为特征的传统污染治理模式。

2.湿法脱硫的硫回收。我国化肥厂的脱硫脱硝设备不仅承担着净化气体的任务,同时还要将硫化氢转变为单体硫,但这一硫资源回收率不高,不少被排放流失,而且塔内易形成硫堵,严重影响生产。过细的硫颗粒不易过滤回收,对填料和器壁附着力也强。因此设法使硫粒子尽量变粗,脱硫液中悬浮硫尽量减少,将有助于该问题的解决。
