| 摘要:以旧瓦楞纸板（OCC）制浆过程中产生的精筛渣为原料，探索高频疏解-浮选联合工艺对杂质去除与纤维回收的影响。结果表明，高频疏解段可将大胶黏物总量削减63%以上，大粒径尘埃去除40%以上；可显著提升纸浆强度，抗张指数与耐破指数分别提高86.2%与104.4%；浮选段可进一步将残余大胶黏物量降低至原水平的3%以下，去除28.8%的尘埃，纸浆抗张指数与耐破指数可进一步提高10.0%与10.2%。经高频疏解-浮选联合处理，系统排出的浮渣生产量为2~4 kg/t浆，热值达20 MJ/kg，具备作为清洁燃料的潜力，但其灰分中检出锌元素，后续利用需防范环境累积风险。 |
| Abstract:Using fine screening residues generated during the pulping process of old corrugated containers (OCC) as raw material， this study explored the effect of a combined process involving high-frequency shear disintegration and flotation on impurity removal and fiber recycling. The results showed that the high-frequency disintegration stage could reduce the total amount of macro stickies by over 63% and remove over 40% of large-sized dirt， while significantly enhancing the strength of the resultant pulp， with tensile index and burst index of pulp increasing by 86.2% and 104.4%， respectively. The flotation stage could further reduce residual macro stickies to below 3% of the original level， remove 28.8% of dirt， and improve the tensile index and burst index of pulp by an additional 10.0% and 10.2%， respectively. After treatment with the combined high-frequency shear disintegration and flotation process， the amount of discharged flotation reject was 2~4 kg/t of pulp， with a calorific value reaching 20 MJ/kg， demonstrating its potential as a clean fuel. However， zinc was detected in the ash content， indicating that subsequent utilization require measures to prevent environmental accumulation risks. |
