摘要
面粉多点供料气力输送系统是通过多储料罐实现企业提出的物料在混料工艺前需要存储数天的特定要求,同时达到连续供料目的,该系统大大提高了企业的自动化程度,但由于气力系统本身具有能耗大的缺点,如果系统输送工艺参数设计不当,会产生非常高的能耗,因此从企业的经济效益角度考虑,对该系统能耗的研究是非常重要的问题,该文为合理设计气力输送系统参数,通过正交实验设计方法,分析料气混合比、气力输送速度、管道直径三者对能耗的影响,从而得出料气混合比与气力输送速度对能耗的影响最为显著,而管道直径的影响相对较小,为进一步对系统能耗的回归分析与工艺参数优化提供理论依据。
On the design of flour multi–supply pneumatic conveying systems,multi–tanks are used for specific requirement of materials needed to be stored for a few days before mixing process,while meeting the goal of continuous supply,it improved the automation degree for the enterprise greatly, however,due to the pneumatic conveying system itself has a large energy consumption shortcoming, if parameters of the system is poorly designed,it will cause a very high energy consumption,from the perspective of economic efficiency of enterprise,it is important to study on the energy consumption of the system. This article is for the rational design of pneumatic conveying system parameters,by orthogonal experimental design,analysed the feed–gas mixture ratio,pneumatic conveying velocity, pipe diameter,then drew a conclusion that feed–gas mixture ratio and pneumatic conveying speed make significant impact on the energy consumption,and that of the pipe diameter is relatively small,it will provide a theoretical basis for regression analysis and further process parameters optimization of energy consumption.
