【摘要】 在WFGD系统中,净烟气携带的浆液液滴引起后续设备的腐蚀堵塞,带来的景观污染问题影响周围居民的正常生活。为了精确量化脱硫后净烟气携带浆液量,提出了适用于环境监测专业的测试取样分析方法,并对该方法进行了讨论分析。实验结果表明:该方法的适用范围为净烟气浆液液滴含量在1.1 mg/Nm3以上,通过对取样分析关键环节的讨论分析,完善和修正了目前取样分析方法中的不足,为环境监测等相关专业提供了一套很有实际应用价值的方法。更多还原

【Abstract】 Slurry droplets carried by flue gas after WFGD would cause corrosion and blockage of the succeeding equipments,and affect residents in the surrounding.A revised method applicable to environmental monitoring was put forward combined with the relevant criterion to improve the accuracy of current means,and the factors such as sampling and analyzing were discussed at the same time.The results show that it was more precise and practicable than used ones,the detection limit of the modified method was 1.1 mg/Nm3,and had significant advancement for measuring slurry droplet of purified flue gas for environmental monitoring aspect.更多还原
