技术领域
本发明属于节能减排技术领域，具体提供一种矿井回风余热回收专用热管。
背景技术
2016版《煤矿安全规程》第137条规定：“进风井口以下的空气温度必须在2℃以上”。为实现冬季煤矿井口保温防冻，目前主要采用燃煤和热泵技术。采用燃煤技术给井口供暖，需消耗大量煤炭和电能资源，风井离主矿区远，每年用煤运输工作繁重，且燃煤污染环境、影响健康，不符合节能减排和环境保护的国家战略需求；热泵装备系统复杂，包括热泵主机、各类循环水泵、各种水处理设备、配套管路、阀、电气及控制设备、大型机房，造价高、运行维护费用较大。
矿井回风温度常年相对稳定，且湿度大，热焓值高，即矿井回风是一种稳定的优质余热资源，将矿井回风余热充分地利用可解决井口防冻问题。热管是一种通过工质相变进行热交换的换热元件，能够实现无动力热交换。然而采用常规热管技术实现矿井进回风热交换存在以下难题：(1)所需热管长、冷凝回流困难、制造难度大、成本高；(2)矿井进回风温差小，换热量大，工质调配困难；(3)矿井回风含粉尘及腐蚀性成分，影响换热管热效率及可靠性。
