多相流管网系统效应影响因子模型研究
|
摘要
本文结合工程实际需要,开展了基于多相流介质下,风机管网系统效应及其附加阻力计算方法和主动减阻的研究,提出了多相流管网系统效应影响因子模型。开发出"风机管网阻力及系统效应附加阻力计算软件",成功应用于某有色冶炼企业管网系统匹配的工程中。该软件的应用解决了风机与系统的匹配性问题,大大降低了系统阻力,提高了风机运行效率,降低了设备实际运行能耗。
This paper concerns with the system effect, a method for the additional resistance calculation of a fan pipe network based on a multi-phases flow medium, and the active reduction of the resistance of the system. A model for the influencing factor for the system effect of the multi-phase flow pipe network is proposed and the software for the calculation of the resistance of the fan pipe network and the additional resistance of the system effect is developed. The software was successfully applied to a non-ferrous metallurgy enterprise pipe network system, which greatly reduced the system resistance,solved fan/system matching issues and improved the fan efficiency. In total, this greatly reduced the energy consumption of the system in actual operation.
