Abstract

An experimental study of the adsorption process of carbon and nitrogen oxides was carried out at various flue gas flow rates and concentrations of harmful components. The optimal conditions for the adsorption process were determined at various flue gas flow rates. It has been demonstrated that the efficiency of adsorption of carbon and nitrogen oxides depends on the flue gas flow rate, the concentration of these components and the process temperature. A design has been developed for an environmentally friendly nozzle for a chimney using granulated blast furnace slag as an adsorbent, which allows achieving a degree of gas purification of 50–55% or higher under optimal operating conditions.

利用粒状高炉矿渣清除烟气中有害成分过程的实验研究
在不同的烟气流速和有害成分浓度下,对碳和氮氧化物的吸附过程进行了实验研究。确定了不同烟气流速下吸附过程的最佳条件。结果表明,碳和氮氧化物的吸附效率取决于烟气流速、这些成分的浓度和工艺温度。已开发出使用粒化高炉矿渣作为吸附剂的环保型烟囱喷嘴设计,在最佳运行条件下,可使气体净化程度达到 50-55% 或更高。
