摘要： 随着各个省份不断提高并执行新的生活垃圾焚烧大气污染物排放地方标准,老旧垃圾焚烧发电厂烟气处理系统的提升改造势在必行。脱酸系统作为垃圾焚烧发电厂烟气处理系统的重要组成部分,在烟气处理系统中主要起到处理硫化物的作用。小苏打干法脱酸系统与半干法脱酸系统的配合投用可以更好地降低排放烟气中二氧化硫的含量。现就小苏打脱酸的脱硫原理、工艺功能及使用过程中影响生产的原因进行总结,以期为提高系统工效提供借鉴。

Abstract: With the continuous improvement and implementation of new local standards for the emission of atmospheric pollutants from household waste incineration in various provinces,it is necessary to upgrade and renovate the flue gas treatment systems of old power plants. The deacidification system,as an important component of the flue gas treatment system in waste incineration power plants,mainly plays a role in treating sulfides in the flue gas treatment system. The combination of dry and semi-dry deacidification systems using baking soda can better reduce the content of sulfur dioxide in the emitted flue gas. This article summarizes the desulfurization principle,process function,and reasons that affect production during the use of baking soda deacidification,providing reference for improving system efficiency.

Key words: baking soda, dry deacidification, semi-dry deacidification, sulfur dioxide
