摘　　要：介绍了废弃物焚烧烟气中HCl气体的生成机理及各种脱除方法 ,并对各种方法的适用场合进行了分析 ,指出了发展方向。根据我国废弃物的组成特点 ,推荐了适用且比较简单的干式系统 ;并进一步介绍了提高干式系统吸收效率的几种方法 。This paper introduces HCl forming mechanism during municipal solid wastes incineration and several methods of HCl gas removal from the incinerator flue gas. Suitability and application of each method was analyzed and the outlook of its development is estimated. According to the features of the municipal solid wastes in China, dry scrubbing system is recommended for its simplicity and applicability. Furthermore some methods has been presented to improve the efficiency of dry scrubbing systems. Especially, modifying slaked limes with alkali additives to enhance their reaction capacity with acidic gases when used as dry absorbents, what is under research is introduced.
