1熔炼低品位电子废料中铜的湿法冶金选择性回收显示文摘比较从低品位电工电子废料中选择性回收铜的3种湿法冶金方法。首先将废料熔炼成Cu-Zn-Sn-Ag合金,并采用SEM-EDS和XRD进行表征。对合金进行阳极溶解,首先采用氨溶液和硫酸溶液对合金进行电沉积或在氨-硫酸铵溶液中浸出,然后进行电沉积铜。实现了各种金属分离,Pb、Ag和Sn等沉积在阳极泥中,而铜则转移至电解液中并在阴极上还原析出。最佳的处理条件为在硫酸溶液中浸出,获得的最终产品为高纯Cu(99%),电流效率为90%。采用氨浸出可使Cu离子富集在电解液中,利于后续的电沉积,但是自发溶解的速率较低。在氨-硫酸铵溶液中进行阳极溶解不利于各种金属在阳极泥、电解液和阴极沉积物进行分离。Ewa RUDNIK Karolina KOLCZYK Dawid KUTYLA 2015Transactions of Nonferrous Metals Society of China2015,25,8:4
2基于Matlab/Simulink的PMSM磁场定向控制算法的设计与应用(英文)显示文摘随着微处理器的快速发展,永磁同步电动机(PMSM)驱动系统广泛应用于需要高精度控制的工业领域。为了克服设计PMSM系统的复杂和费时的局限性,提出一种PMSM速度控制的磁场定向控制算法(FOC)。该算法在HATLAB/Simulink中实现,利用其中的标准模块,利用Matlab的自动代码生成工具,可在DSP微处理器中实现。采用了STM32F4微控制器。为处理电流反馈信号,引入主动式电流读取误差补偿器。利用由3个双向5-A Hall传感器执行的模数转换器,使信号精度达10mA、10Bit。在0~2000r/min范围内,试验了带传感器的PMSM。对期望速度的阶跃响应实验表明:整个系统的动态性能和稳态性能良好。Pawel Stojaczyk Dawid Woroch 洪波 危银涛 2014汽车安全与节能学报2014,5,2:3
3Linking renewables and fossil fuels with carbon capture via energy storage for a sustainable energy future显示文摘Renewable energy sources and low-carbon power generation systems with carbon capture and storage(CCS)are expected to be key contributors towards the decarbonisation of the energy sector and to ensure sustainable energy supply in the future.However,the variable nature of wind and solar power generation systems may affect the operation of the electricity system grid.Deployment of energy storage is expected to increase grid stability and renewable energy utilisation.The power sector of the future,therefore,needs to seek a synergy between renewable energy sources and low-carbon fossil fuel power generation.This can be achieved via wide deployment of CCS linked with energy storage.Interestingly,recent progress in both the CCS and energy storage fields reveals that technologies such as calcium looping are technically viable and promising options in both cases.Novel integrated systems can be achieved by integrating these applications into CCS with inherent energy storage capacity,as well as linking other CCS technologies with renewable energy sources via energy storage technologies,which will maximise the profit from electricity production,mitigate efficiency and economic penalties related to CCS,and improve renewable energy utilisation.Dawid PHanak Vasilije Manovic 2020Frontiers of Chemical Science and Engineering2020,14,3:3
