冷凝再加热技术对废碱液焚烧系统烟气消白效果研究

Study on the Whiten Effect of Condensation Reheating Technology of Flue Gas in Waste Alkali Liquor Incineration System

本文介绍了新疆某煤制烯烃项目废碱液焚烧系统排放烟气消白除湿改造实例,通过采取冷凝再加热工艺技术对烟气排放系统改造,使排放烟气实现“消白”的目的,此外,烟气中的NOx以及烟尘等物质也随水蒸汽沉降一部分,有效降低了烟气中NOx、CO以及烟尘排放量,可供同类装置环保升级参考。

This paper introduces an example of whiten and dehumidification of flue gas discharged from waste alkali liquor incineration system of a coal to olefin project in Xinjiang.By adopting condensation reheating technology to reconstruct the flue gas emission system,the purpose of"whitening"is realized.In addition,NOx and other substances in the flue gas also settle with steam,which effectively reduces NOx,CO and flue gas emissions,it can be used as a reference for environmental protection upgrading of similar devices.
