非电烟气治理半干法脱硫技术现状及发展趋势分析

Analysis on Present Situation and Development Trend of Semi-dry Desulfurization Technology for Non-electric Flue Gas Treatment

随着我国火电超低排放改造逐渐完成,以及相关非电行业烟气排放政策、法规的实施,大气治理重点由电力行业转向非电行业。半干法因具有投资低、无废水、系统简单等特点,越来越多应用于非电行业烟气治理。因此,本文对各种主流半干法技术进行介绍与特点分析,并结合典型电力与非电烟气特点对比,提出了非电烟气半干法治理技术发展方向,为非电烟气治理和半干法技术发展提供参考与借鉴。

With the gradual completion of the ultra-low emission transformation of thermal power in China, and the implementation of related policies and regulations on flue gas emission in non-electric industries, the focus of atmospheric governance has shifted from the power industry to the non-electric industry. The semi-dry method is more and more used in non-electric industry because of its low investment, no waste water, simple system, etc.. Therefore, this paper introduced and analyzed the characteristics of various mainstream semi-dry technology, and combined the characteristics of typical electric and non-electric flue gas, put forward the development direction of semi-dry desulfurization technology for non-electric flue gas treatment, so as to provide reference for non-electric flue gas treatment and semi-dry technology.
