一种高效矿井回风间接井筒防冻装置
本技术涉及矿井设备领域,具体涉及一种高效矿井回风间接井筒防冻装置。
技术介绍
煤矿是个巨大的蓄热体,蕴藏丰富的地热资源。进入煤矿的空气不断与煤矿进行热交换,最终,空气与煤矿的地温达到平衡。煤矿的地温基本恒定,致使煤矿回风的温度全年基本恒定,受外界气温的影响很少。故而,煤矿回风是一类稳定的较优质的余热资源。煤矿回风量约等于进风量,回风温度远高于进风温度,因此利用回风加热进风满足部分或全部井筒防冻负荷是可行的。现有的回风利用技术均采用喷淋的方式将回风的热能转换到水中,再利用水源热泵提取水中的热能的方式,属于间接利用回风热能,该方式环节较多,效率不高。寒冷季节里当矿区室外气温低于0℃时,如果入风井筒防冻问题解决得不好,井筒淋水会在低温空气作用下,在井壁、井筒内的罐道、罐道梁、提升容器、电缆、水管等处结冰,使井筒提升能力下降,通风断面减小,还可引起卡罐、托罐闸启闭不便、防坠保险失灵等,严重时大块冰塌落,造成损坏井筒设备和人员伤亡的重大事故,影响矿井安全生产。因此,矿井井筒防冻对保证煤矿冬季正常生产十分重要,井筒防冻热负荷在煤矿供热负荷中占较大比例。
