氨对平板显示玻璃窑炉烟尘性质的影响

文章导读

摘要通过平板显示玻璃窑炉烟气脱硝除尘装置，考察氨组分对烟尘析出温度、含水量及烟尘性质的影响规律。结果表明，烟尘析出温度随着烟气中氨浓度的增加而提高，烟尘含水量也明显增大，平均含水量约为7%~8%。通过扫描电镜和粒度分布仪表征，烟气中氨710 mg·Nm^-3时，与无氨烟气比较，烟尘中出现氧化硼氨水合物，烟尘颗粒出现积聚现象，粒径明显增大，有利于烟尘的脱除。

Abstract： In this work, by a de-NO_x and dust removal device, the effects of ammonia on temperature of dust deposition, water content of dust, and properties of flue gas dust were investigated. The results showed that, with the increase of the concentration of ammonia, the temperature of dust deposition increased obviously, at the same time, the water content of dust increased too, the average water content in the dust is in the range of 7%~8%. Based on results of SEM and granularity distribution, when the concentration of ammonia reached 710 mg·Nm^-3 in flue gas, the boron oxide ammonia hydrate was found in the dust, particle accumulation occurred, and average size of particle increased, which was helpful for the removal of dusts.
