计算机辅助煤泥浮选捕收剂设计

Computer-Aided Coal Slime Flotation Collector Design

摘要: 煤泥浮选作为选煤厂的重要工艺环节，其效率与效果直接影响到煤炭资源的回收率和产品质量。捕收剂在煤泥浮选中起到至关重要的作用，能够定向调控矿物表面亲疏水性，从而提高浮选效率。然而，传统的捕收剂设计往往依赖于经验性试探，不仅工作量大，而且效果不佳。本文提出了一种基于计算机辅助的煤泥浮选捕收剂设计方法，通过构建3D-QSAR模型，实现捕收剂分子结构的精准设计。实验结果表明，该方法能够显著提高捕收剂的性能，降低药剂用量，提高浮选效率。

Abstract: As an important process of a coal preparation plant, the efficiency and effect of slime flotation directly affect the recovery rate of coal resources and product quality. Collectors play a vital role in coal slime flotation, which can directionally control the hydrophilicity and hydrophobicity of mineral surfaces so as to improve flotation efficiency. However, the traditional collector design often relies on empirical tests, which not only has a large workload, but also has poor results. In this paper, a computer-aided design method for coal flotation collector is proposed. By constructing a 3D-QSAR model, the precise design of the collector molecular structure is realized. The experimental results show that this method can significantly improve the performance of the collector, reduce the dosage of the reagent and improve the flotation efficiency.
