焦化厂污染土壤热脱附修复尾气净化技术研究

Research on purification of off-gas from thermal desorption for contaminated soil in coking plant

从有机污染物类型、热脱附工艺、土壤类型角度出发,探讨了冷凝、吸附、热力燃烧、催化燃烧等热脱附尾气有机污染物净化技术及粉尘净化技术,确定了典型的热脱附尾气净化技术,同时简要介绍了一些新型的热脱附尾气净化技术,并对今后的技术发展方向提出展望。

This paper discusses the organic pollutant purification technology for off-gas from thermal desorption during condensation,adsorption,thermal combustion,and catalytic combustion as well as dust purification technology from perspective of the organic pollutants type,thermal desorption process and soil type.A typical technology for purifying off-gas from thermal desorption is decided.Some new off-gas purification technologies are also introduced.A future technological development is prospected.
