基于响应面法的无烟煤煤尘降尘剂配方优化

Optimization of Formula of Dust Remover for Anthracite Coal Dust Based on Response Surface Methodology

摘要: 为了改善煤尘表面的润湿效果,添加表面活性剂以提高煤尘表面的润湿性,采用响应面分析法对降尘剂配方进行优化设计。选取非离子表面活性剂烷基糖苷APG(A)、阴离子表面活性剂SDBS(B)和阳离子聚丙烯酰胺PAM(C)作响应变量,以沉降时间t和透过率作为响应值,按照Box-Behnken中心组合实验设计原理,对无烟煤降尘剂进行了优化。结果表明,煤尘润湿性最好时各成分的最佳浓度为:0.15%APG,0.43%SDBS及0.03%CPAM,沉降时间预测值为10.761 9 s,透过率预测值为89.850 5%,可同时达到润湿和团聚的最佳状态。

Abstract: To improve the wetting effect of coal dust surface, surfactant is added to improve the wetting effect of coal dust surface. In this paper, the response surface analysis method is used to optimize the design of the formula of dust remover. Taking nonionic surfactant APG(A), anionic surfactant SDBS(B) and cationic surfactant CPAM(C) as response variables, with sedimentation time t and transmittance as response values, according to Box-Behnken center combination experiment design principle, the anthracite coal dust agent is optimized. The results show that the optimum concentration of each component is 0.15%APG, 0.43%SDBS and 0.03%CPAM, the predicted value of sedimentation time is 10.761 9 s, and the predicted value of transmittance is 89.850 5%, which can reach the optimal state of wetting and agglomeration at the same time.
