一种脱白零排放系统
本专利技术涉及湿法脱硫后烟气处理机械设备领域,具体涉及一种脱白零排放系统。
技术介绍
我国火电燃煤锅炉烟气100%上了脱硫,其中超过90%采用湿法,通过采用低低温电除尘器和/或末端湿式静电除尘器改造,可以满足新国标(GB13223-2011)要求、甚至实现超低排放。抛开投资和运行成本问题不说,就算我国各种燃煤锅炉都达到超低排放水平,也不能彻底解决大气雾霾污染,原因是现行标准规范有一大缺失,就是没有排放烟气湿度的控制指标,而这恰恰是形成雾霾的根源。燃煤锅炉湿法脱硫系统排烟带出的水分,以300MW机组为例,脱硫系统每小时消耗水120m3/h,包括原烟气带水分71.8m3/h、脱硫增加40m3/h,年耗水量~100万吨。按照燃烧吨煤放散烟气10000Nm3/t、湿烟气所含水分112g/Nm3估算,每燃烧1吨煤湿烟气带走水份1吨,主要包括煤中原始含水、脱硫补充水,2014年全国消耗煤36-37亿吨,燃煤烟气带入大气的水份高达三十多亿吨。由于锅炉烟气大多采用湿法脱硫工艺进行脱硫处理,导致产生大量含湿量较高的湿烟气,排放到大气中,水蒸气就会结露,出现白色烟 ...
