烟道气中二氧化碳矿化利用研究

On the Utilization of Carbon Dioxide From the Flue Gas

通过用白灰做胶凝剂的成型材料,控制反应温度在4℃-128℃的范围内,来捕集烟道气中低浓度的二氧化碳、二氧化硫、二氧化氮、一氧化氮,并将其固存在成型材料中,使二氧化碳、二氧化硫矿化成为产品的组成部分,得到多种早强的白灰气硬性产成品,并由此得到二氧化碳、二氧化硫、二氧化氮、一氧化氮枯竭的烟道气。其主要用途是:可用于燃煤发电厂的二氧化碳、二氧化硫、二氧化氮、一氧化氮的减排,并使其固体排放物得到综合利用,得到早强的白灰成型材料产成品。

With the agglomerating agent with lime , controlling the reaction temperature in the range of 4 DEG -128 DEG C, people can capture the low concentration of flue gas__carbon dioxide , sulfur dioxide , nitrogen dioxide , nitric oxide , and the existence of solid molding materials, CO2,SO2,a variety of early strong lime gas rigid products.The carbon dioxide, sulfur dioxide, nitrogen dioxide , nitric oxide depletion can be used for coal -fired power plant carbon dioxide , sulfur dioxide , nitrogen oxide , two nitric oxide emission reduction .The utilization of solid wastes can make the finished product with lime molding material .
