摘要
针对我国北方煤矿井下通风系统在冬季时非常容易出现风门结冰、风门运转不良、风门开闭困难等问题,本文设计了煤矿井下通风系统,提出了一种利用电动机驱动的煤矿井下防结冰风门,利用循环热蒸汽持续给风门加热,可以有效避免风门结冰。为了研究风门在正常工作过程中内部的热循环效果,采用Fluent软件对风门的内部热流场进行仿真研究,对比了两种加热装置结构,最终得出第一级导流板的角度对温升和压降的影响最为显著,优化后的结构温升提高了2.82%,内部的流动和传热性能更好,说明在外部温度较低时,风门始终能够保持在较高温度,不会结冰,取得了满意的仿真结果。
In view of the northern coal mine ventilation system in winter is very easy to appear when wind door ice,bad valve operation,wind door opening and closing difficult problems,this paper on the coal mine ventilation system design,put forward a kind of motor drive coal mine anti-icing windshield,using circulating hot steam continue to heat the door,which can effectively avoid the door ice.In order to study the internal heat cycle effect of the valve in the normal work,using Fluent software on the internal heat flow field of simulation research,comparing the structure of the two heating device,the first diversion angle on temperature rise and pressure drop is the most significant,the optimized structure temperature rise increased by 2.82%,the internal flow and heat transfer performance is better,that in the external temperature is low always can keep at a high temperature will not freeze,achieved satisfactory simulation results.
