摘要
文章对比了在超低排放背景下的各种除尘技术对氢氧化铝〔Al(OH)3〕焙烧炉烟气净化的适应性,提出了其最佳可行技术,即高温超净电袋复合除尘技术,阐述了该技术的原理及特点,重点介绍了山东某厂1#炉3000t/d Al(OH)3焙烧炉项目电除尘器改造配套采用高温超净电袋复合除尘器技术方案,性能测试结果表明经改造出口颗粒物的排放浓度小于5mg/Nm^3,达到超低排放的要求。该技术的成功应用,验证了其除尘效率高、运行阻力小、维护费用低、无二次污染等优点,可大幅提高副产物回收率,降低除尘设备电耗,减少排污费,具有良好的经济效益和社会效益。
Under the background of ultra-low emission policy,this paper compared the adaptability of each precipitator technology to the flue gas purification of aluminum hydroxide roaster;proposed the best available technology,namely the High-temperature Ultra-clean Electrostatic-Fabric Integrated Precipitator technology;and introduced the principle and characteristics of the technology.This paper emphatically introduced the High-temperature Ultra-clean Electrostatic-Fabric Integrated Precipitator technology solution to the transformation of No.13000t/d aluminum hydroxide roaster project in a Shandong plant.The performance test results showed that the emission concentration of particulate matter at outlet was less than 5mg/Nm3,reaching the requirements of ultra-low emission policy.The successful application of the Hightemperature Ultra-clean Electrostatic-Fabric Integrated Precipitator technology in the aluminum hydroxide roaster shows the advantages of high dust removal efficiency,low running resistance,low maintenance costs and no secondary pollution.The technology can greatly improve the by-product recovery rate,reduce the power consumption of dust removal equipment,and reduce the pollution discharge fees,so it has good economic and social benefits.
