化工厂废水管道电伴热装置

信息来源:皖缆集团 浏览次数:963 发布时间:2017-05-15

    废水管道电伴热装置是一种发热效率较高的防冻保温系统,结构简单、安装便捷(见下图)。与传统的防冻保温方式相比可节省成本达30%以上,效果提升更加明显。这种电伴热装置的发热元件为伴热带,可适用于有各种防爆要求的场所,安全又节能。

 

废水管道电伴热装置


    山东一大规模化工厂的废水管道,在去年冬天因结冰情况而造成停产。原计划是考虑被动式的保温方式,也就是管道外面增加保温棉和外防护。由于当地极端气温会低至零下23℃,即使采用了被动式保温也不能有效的解决管道结冰情况。后来,决定采用皖缆集团生产的废水管道电伴热装置,以主动式的保温方式来解决管道结冰现象。该装置既能提前预防管道中的介质冻结,又可在介质结冰后迅速化冰。

 

废水管道电伴热装置的安装图


    该化工厂的废水管道电伴热装置主要由伴热带、配电控制箱、中间接线盒、尾端、固定胶带等组成。管道直径48MM,距离较远,支管道较少,选择恒功率伴热带较为适合。该伴热带单回路使用距离长,发热量高,且温度能精确控制。只需单根直铺,安装在管道下方的45度角(见上图)。采用这种方案可节省前期投入与后期运行成本,让冬季的废水管道再也不会出现结冰情况。
