    摘 要:發(fā)電機(jī)氫氣純度偏低不僅將提高機(jī)組運(yùn)維成本,造成經(jīng)濟(jì)損失,還會(huì)形成潛在的設(shè)備安全隱患。結(jié)合浙江省內(nèi)發(fā)電機(jī)組實(shí)際運(yùn)行經(jīng)驗(yàn),從密封性、密封油和氫氣氣源多角度分析發(fā)電機(jī)氫氣純度偏低的常見原因,并分別介紹基于金屬氫化物提純和儲(chǔ)存雙重功能的氫氣綜合提純系統(tǒng)和基于薄膜蒸發(fā)原理的密封油提純裝置的工作原理、結(jié)構(gòu)組成、提純流程和應(yīng)用情況。兩種典型氫氣提純裝置應(yīng)用后,發(fā)電機(jī)氫氣純度均顯著上升,采用的氫氣純度偏低原因分析方法和提及的氫氣提純裝置對(duì)相關(guān)人員具有一定的借鑒作用。

    Abstract: Low purity of generator hydrogen not only increases the operating costs of generation units, but also creates safety risks to the generator. According to the practical experiences of generator operation in Zhejiang, an integrated analysis on the common causes of low purity of generator hydrogen is presented from the perspective of sealing, sealing oil and hydrogen gas source. Two typical hydrogen purification devices, the comprehensive hydrogen purification system with both functions of purification and storage of metal hydride and the sealing oil purification device based on the thin film evaporation theory, are introduced in aspects of working principle, structure, purification process and application. As a result, the hydrogen purity of generators increases significantly by using that two devices. Lastly, this review could provide some references to relevant researchers.
    Key words: generator; hydrogen purity; purification device
