Abstract: A new type filter cartridge dust collector with conical structure was studied with cost benefit method, and its economic analysis model established. On this basis, the structural parameters that affect the economic performance of the dust collector, such as the pleat number of filter cartridge and conical structure (N2 and N1), conical height (h1), cone radius and pleat height of the conical structure (r and h2) were analyzed, and their influential trend and significance on the economic benefit cost ratio (EBCR) of the new filter cartridge also analyzed using response surface methodology on Minitab software code platform. Two polynomial prediction models of influential factors were obtained, and then the structural parameters optimized. The results show that the influential conspicuousness of the above structural parameters on EBCR is N1 > N2 > h2 > h1, and the effect of r can be negligible. In addition, within the ranges of parameters in this study, the optimal values of structural parameters are N1=264, N2=350, h1=0.8 m, and h2=0.05 m, respectively, and the maximum value of EBCR is 33.25%.

摘要： 以内部具有锥体结构的新型滤筒除尘器为研究对象，基于成本效益法建立新型滤筒除尘器的经济性分析模型，对影响新型滤筒除尘器经济性的结构参数如滤筒褶数、锥体褶数、锥体高度、锥体上圆台半径及锥体褶高进行分析，基于Minitab软件代码平台利用响应面法分析结构参数对效益成本比的影响趋势和显著性，得到各影响因子的二次多项式预测模型，并优化其结构参数. 结果表明，结构参数对效益成本比影响的显著性水平为锥体褶数(N1)>滤筒褶数(N2)>褶高(h2)>锥体高(h1)，而锥体上圆台半径r的影响不显著. 在给定的参数范围内，当N1=264, h1=0.8 m, N2=350, h2=0.05 m时，取得的最大效益成本比为33.25%.
