变频电磁除垢装置在李楼煤业的研究与应用

Research and Application of Frequency Conversion Electromagnetic Descaling Device in Lilou Coal Industry

李楼煤业能源中心能源站循环系统设备和管道内部易产生腐蚀、结垢,造成设备、管道严重腐蚀,对能源站的稳定运行产生了严重影响。针对化学除垢+人工除垢的方案成本高,对各种化学药剂投放时间、投放精度的要求极高,很难适应矿区空调水系统的实际工作需求,人工除垢则存在着效率低、盲区大、安全性差的不足问题,提出了一种新的变频电磁除垢装置,能够产生交变的高频电磁场,管道内的水分子在经过高频电场时能够被磁化,降低水质中各种结垢离子的结晶性,进而提升防垢效果。通过挂片试验对比,在采用电磁除垢装置以后,能够将空调水系统中的平均腐蚀速率降低67.7%,有效地提升了李楼煤业空调系统的应用可靠性。

The circulation system equipment and pipelines inside the energy station of Lilou Coal Industry Energy Center are prone to corrosion and scaling,causing severe corrosion of the equipment and pipelines,which has a serious impact on the stable operation of the energy station.A new frequency conversion electromagnetic descaling device is proposed to address the high scheme cost of chemical descaling+manual descaling,which require extremely high requirements for the administration timing and administration accuracy of various chemical agents,making it difficult to meet the actual working needs of the air conditioning water system in mining areas.Artificial descaling also has shortcomings such as low efficiency,large blind spots,and poor safety.It can generate alternating high-frequency electromagnetic fields,and the water molecules in the pipeline can be magnetized when passing through the high-frequency electric field,reducing the crystallinity of various scaling ions in the water quality and improving the anti scaling effect.Through the comparison of hanging piece tests,after adopting the electromagnetic descaling device,the average corrosion rate in the air conditioning water system can be reduced by 67.7%,the application reliability of the air conditioning system in Lilou Coal Industry is effectively improved.
