间壁式换热器矿井乏风废热利用技术与工程实例研究

Study on the Technology and Engineering Example of Waste Air Waste Heat Utilization in Partition Wall Heat Exchanger

矿井乏风中蕴含着大量的低温余热可以用于寒冷地区和夏热冬冷地区冬季井口防冻。本文在对麦垛山煤矿的余热资源进行调研和方案分析的基础上,采用了乏风废热直接换热解决井筒防冻问题的方案。

Mine exhaust wind contains a large amount of low-temperature waste heat that can be used to prevent freezing at the wellhead in winter in cold areas and hot-summer cold-winter areas.Based on the investigation and analysis of the waste heat resources of Maidoushan Coal Mine,this paper adopts a scheme for direct heat exchange of waste air waste heat to solve the problem of antifreeze in the wellbore.
