高温滤料对去除有害气体方面的研究

Research on Removal of Harmful Gas by High Temperature Filtering Material

钢铁、水泥、煤电等高耗能企业生产中所产生的高温烟尘不仅导致空气中含尘量增大,同时还伴随有大量的氮氧化物、硫化物等有害气体的排放,导致雾霾产生,大气污染严重。烟尘的治理集中于除尘及脱硫脱硝以除去有害气体。分析了当前烟尘治理的研究现状,对袋式除尘器及其滤袋的研究成果及现有脱硝技术予以归纳总结,为今后研究思路和方向提供借鉴。

High temperature dust produced by high energy consuming enterprises in iron and steel,cement and coal industries not only leads to the increase of dust content in the air,but also is accompanied by large amount of nitrogen oxides,sulfur compounds and other harmful gas emissions,which leads to smog appearance and serious air pollution. Dust treatment focuses on the removal of dust,desulfurization and denitration to get rid of harmful gas. The research status of present dust treatment was analyzed,the research result of bag dust collector and its filter bag and existing denitration technology were summarized in order to provide reference for future research thinking and directions.
