摘要
通过理论分析和试验研究发现，利用锅炉碱性排污水或化学碱性水对锅炉尾部烟道进行喷雾，可以达到脱除烟气中SOx、MOx的目的，并取得了良好效果。其技术关键是喷淋雾化方式、喷雾水量、喷雾水的碱度及烟道结构对气-汽两相流之间混合湍动的影响。该方法具有投资少、运行费用低、运行简单可靠、脱硫脱氮效果好、不产生二次污染和烟道阻力及腐蚀小等特点。针对我国燃煤锅炉量大、面广、分散的特点，该方法具有广阔的应用前景。
Based on the theoretical analysis and test research, it is found that the aim of Sox and Nox removal from the flue gas could be attained using the boiler f s alkaline discharge water or chemical alkaline water to sIJray on the boiler's toe flue, and the better effect is obtained. The key technilues are the spray mode,arnount and alkalinity of water,as well as the influence of flue structure on the mixed turbulency belween gas-vapor two phase flow. This method has the characteristics such as lesser investment, lower operating cost, simple and reliable operation, better effect of sulfur and nitrogen removal, without secondary pollution and lesser resistance influence and corrosion on flue. This method has the wide application prospects with respect to the characteristics of coal combustion boilers in our country.
