电伴热带在公路隧道中得到有效运用

近些年由于气候反常的原因,造成了我国北方大部分城市出现管道冻裂现象,造成了不小的经济损失。随着高速公路的建设、发展,高速公路日趋饱和,越来越多的在建高速基本上为山区高速公路,几乎都涵盖了隧道。如何保证隧道运营的安全性,隧道消防也成为不可或缺的部分。

消防管道和生命安全息息相关,尤其是在北方寒冷的地区,冬季环境温度长期处于冰点之下,新疆、黑龙江等地区甚至低于-30℃,而且隧道口等部位风速较大,温度较低,遇到雨雪天气隧道内部容易长期处于潮湿状态等,因此需要对公路隧道内较长时间处于相对静止状态的消防管道进行防冻处理,以防止因出现冻堵现象而使消防系统陷于瘫痪。

长期以来,冬季北方地区隧道消防管道的保温防冻是一大难题,为了保证消防系统在冬季冰冻期能够正常运行,电伴热的出现较好地解决了这一难题,隧道消防管道采用电伴热系统,有效的防止了管道冻堵现象的出现。电伴热带系统是将电伴热带直接缠绕消防管道来补充热损失,沿自身长度范围调节管道系统每一个控制点的温度,使温度维持在要求的范围内,从而达到防止管道结冰的目的。管道和罐体上安装电伴热系统可以有效地解决管道结冰冻裂现象,电伴热对于高速公路隧道中的管道安全防护起到重要的作用。
