【摘要】：为研究除尘系统结构最优配置,实验采用新型高效水雾荷电振弦栅除尘方法,以除尘效率及阻力损失为参照结果,选定纤维栅板数量、纤维栅与喷嘴间距、纤维栅材料和间隙4个因素进行单因素试验,针对各因素对纤维栅除尘效率的影响进行了分析研究,结果表明多块纤维栅除尘效果明显优于单块纤维栅,正常处理风速时3块纤维栅的除尘效率最高,纤维栅阻力与其数量呈正比;纤维栅除尘效率随间距增大而先增后减,间距为230 mm时除尘效率最高;塑胶纤维栅除尘效果明显优于其他材料,各阻力值排序为:塑胶涤纶不锈钢尼龙;纤维栅除尘效率随纤维间隙增大而降低,其阻力随间隙增大而减小;利用SPSS软件进行4因素三水平正交试验分析,在特定条件下除尘效率显著性排序为:纤维栅数=纤维栅间隙纤维材料纤维栅与喷嘴间距;阻力损失显著性排序为:纤维栅数=纤维栅间隙=纤维材料=纤维栅与喷嘴间距;试验最佳配置为3块间隙0.6 mm尼龙纤维栅板,且纤维栅板距喷嘴最小间距为185 mm。
[Abstract]:In order to study the optimal configuration of the dust collection system, a new high efficiency water mist charged vibrating chord griddle was used in the experiment. The number of fiber grid and the distance between fiber grid and nozzle were selected according to the results of dust removal efficiency and resistance loss. Four factors of fiber gate material and clearance were tested by single factor test. The effect of each factor on the efficiency of fiber grid dust removal was analyzed. The results show that the dust removal effect of multiple fiber gate is obviously better than that of single fiber gate. When the wind speed is normal, the dust removal efficiency of the three fiber gratings is the highest, and the resistance of the fiber grating is proportional to the number of the fibers, and the dust removal efficiency of the fiber grating increases first and then decreases with the increase of the spacing, and the highest is when the spacing is 230 mm. The dust removal effect of plastic fiber grating is obviously better than that of other materials. The order of resistance value is as follows: plastic polyester stainless steel nylon, fiber grid dust removal efficiency decreases with the increase of fiber gap, and the resistance decreases with the increase of gap. SPSS software was used to analyze the four factors and three levels of orthogonal test. Under certain conditions, the order of dust removal efficiency was as follows: fiber grating number = fiber gap fiber gap fiber grating and nozzle spacing; The significant order of resistance loss is as follows: fiber grating number = fiber gate gap = fiber material = fiber gate and nozzle spacing, and the optimum configuration of the test is 0.6 mm nylon fiber grid with 3 gaps, and the minimum distance between the fiber grid and the nozzle is 185 mm.
