Abstract:

高聚物聚氧化乙烯(polyethyleneoxide,PEO)、聚丙烯酰胺(polyacrylamide,PAM)能够减少管道中流体阻力。目前,电厂脱硫主要以湿式石灰石石膏法为主,脱硫系统中循环泵传输浆液产生巨大的阻力耗能。因此,文中针对电厂脱硫系统进行减阻实验研究。模拟实际环境中的生产情况,在湿式石灰石脱硫浆液中,添加不同浓度的减阻剂,研究浆液流体特性以及高聚物的减阻性能。基于影响高聚物PEO、PAM减阻效果的因素实验分析,探索最佳的减阻剂配方。研究表明,高聚物PEO、PAM均存在自最佳减阻浓度;减阻剂配方由PEO、PAM、硫脲3种组分按质量浓度配比3:1:2组成,600mg/L减阻剂的减阻效果最佳,最佳减阻率在40%左右。
