分体式矿井排风余热回收井口防冻系统应用探究

矿井排风中蕴含丰富的低温热能，非极端天气条件下通常利用矿井排风中的低温余热就能够满足井口防冻的用热需求。为了利用矿井排风中的热量解决井口防冻用热问题，提出采用分体式余热回收利用系统。介绍了系统的形式，并以太原市西铭冀家沟煤矿具体的项目为例，进行了系统配置分析。该系统的初投资和运行费用较低，环境效益和经济效益良好，为解决矿井防冻问题提供了一种新方法。

Design and Application of the Antifreezing System for the Head of the Split Type Mine Exhaust and Waste Heat Recovery

The mine exhaust wind contains abundant low temperature thermal energy. Under the non-extreme weather conditions, the low temperature residual heat in the mine exhaust wind can be used to meet the thermal demand of the well head.In order to use the heat in mine exhaust air to solve the problem of heat used in wellhead anti-freezing, a separation type power heat pipe waste heat recovery and utilization system is proposed. This paper introduces the form of the system and analyzes the system configuration by taking a specific project of a coal mine in taiyuan as an example.The initial investment and operating cost of the system are low and the environmental and economic benefits are good.It provides a new method to solve the problem of mine anti-freezing.
