摘要
设计开发了用于滤除工业废水中含铁杂质的新型导轨式永磁磁棒过滤设备,建立了磁场-流场的数学模型和有限元分析模型。通过模型分析了磁棒的选材以及间距对滤除效率的影响,并得出铁铷硼为最合适材料以及磁棒临界间距K值的结论。最后通过铁屑吸附量计算和效益分析证明了该新型磁棒过滤器的高效性与实用性。
In this paper,two main factors which affect the efficiency of scraping slag of magnetic rod filter are put forward,and a mathematical magnetic field-flow model is established. The model is used to analyze the influence factors of bar magnet selection and spacing on slag scraping efficiency. It is concluded that the iron rubidium boron is the most suitable material and the critical spacing K is obtained. At last,the correctness of the conclusion is proved by comparing the amount of iron adsorption.
