稀土合金水处理器阻垢性能评价实验研究

摘要

he antifouling performance of the new Rare-earth Alloy Nanometer Water Treatment (RANWT) is evaluatedby circulating cooling water fouling dynamic simulator. The Experimental conditions: inlet water temperatureof 28.5 ± 0.5 ℃, water bath temperature of 50 ±0.3 ℃, flow rate of 0.4 m. s^(-1) and water hard- ness 1 400.0 mg. L^(-1) ( CaCO3 ). The five groups experiment data were tested on test loop and reference loop and the monitoring parameters include fouling resistance, pH, conductivity and turbidity etc. The results showed that :water treatment average anti-fouling efficiency is 86.4% in high hardness conditions, that the scale inhibition effect of water treatment is better. This water treatment can effect water quality parameter based on analyzing multiple the water quality parameter curves and fouling resistance curves.%为考察新型稀土合金水处理器（下称阻垢器）阻垢性能,本文利用循环冷却水污垢动态模拟试验台,对阻垢器性能进行动态评价实验。在相同实验条件下（入口水温28.5±0.5℃,水浴温度50±0.5℃,流速0.40 m.s-1,水质硬度1 400.0 mg.L-1）,对加装阻垢器和未加装阻垢器两路水质进行动态实验,连续监测污垢热阻和水质参数（包括电导率、pH和浊度等）,进行了5组重复性实验。结果表明：稀土合金水处理器对高硬度水质平均阻垢率达81.6%,抑垢效果较好,从实验水质参数变化和换热器表面积垢状态观察,该阻垢器对水质浊度、电导率、pH等参数有一定影响。
