1978年,郑州铁路分局应用电渗析技术进行机车给水高盐分水质淡化处理,于商邱给水站建成一座中型电渗析水处理设备。电渗析器单台流量20～30吨/时,安装这样大容量的电渗析设备,在铁路上还是第一次。电渗析设备每系列串联2台,总脱盐率60％左右,现已稳定运行三年多。电渗析淡化水供给蒸汽机车使用后,蒸汽质量提高,放水率降低,热能浪费减少,又节水又节煤,并保证了东陇海线机车多拉快跑,安全正点。
In 1978, Zhengzhou Railway Substation applied electrodialysis technology to treat desalination of high-grade salinity water in locomotives, and a medium-sized electrodialysis water treatment facility was built at the water supply station in Shangqiu. Electrodialysis unit single flow of 20 to 30 tons / hour, the installation of such large-capacity electrodialysis equipment, is still the first time on the railway. Electrodialysis equipment series 2 series, the total desalination rate of about 60%, has now been more than three years of stable operation. After electrodialyzed desalinated water is supplied to steam locomotives, steam quality is improved, water discharge rate is reduced, waste of thermal energy is reduced, water is saved, and coal is saved. This ensures that the locomotives on the East China Sea line are running fast and safe.
