Continuous production for large quantity plasma activated water using multiple plasma device setup
摘要：
在本工作中，批量和连续生产等离子体活化水（PAW）的报告。为了以批量和连续的方式生产PAW，使用多个等离子体装置设置。多等离子体装置由一系列同时供电以产生PAW的等离子体装置组成。这种多等离子体装置由自主开发的高压高频电源供电。在这种多等离子体装置设置中产生的空气等离子体被电表征，并且使用光学发射光谱法识别所产生的自由基/物质。等离子体-水暴露后的排放废气携带一些环境污染物（NOx和O3等）。批量和连续PAW生产装置在大体积PAW的生产中利用流出物（污染物）气体。因此，它大大降低了排放到环境中的废气中这些污染物的浓度。间歇工艺生产体积较小（2升）的高反应性PAW。此外，在连续工艺中，生产具有低反应性的大体积（20升）PAW。高活性PAW和低活性PAW用于不同的应用。微生物灭活使用高反应性PAW来进行除菌（细菌、真菌、病毒和害虫）、食品保存、选择性杀死细胞等，而低反应性PAW在种子发芽、植物生长中具有应用，并且作为农业和水产养殖应用的氮源等。此外，批量和连续PAW生产设置设计是可扩展的，因此，可用于PAW生产的工业中。
英文摘要：
In the present work, a batch and continuous production of plasma-activated water (PAW) is reported. To produce PAW in a batch and continuous manner a multiple plasma device setup is used. The multiple plasma device consists of a series of plasma devices that are powered simultaneously to produce PAW. This multiple plasma device is powered by indigenously developed high-voltage high-frequency power supply. The air plasma generated in this multiple plasma device setup is electrically characterized and the produced radicals/species are identified using optical emission spectroscopy. The post-discharge effluent gases left after plasma-water exposure carries some environmental pollutants (NOx and O3, etc.). The batch and continuous PAW production setup utilizes effluent (pollutants) gases in production of large volume PAW. Hence, it substantially reduces the concentration of these pollutants in effluent gases which are released in environment. The batch process produces high reactive PAW with less volume (2 liters). Moreover, in a continuous process, a high volume (20 liters) with low reactivity of PAW is produced. The high reactive PAW and low reactive PAW are used for different applications. Inactivation of microbes (bacteria, fungi, viruses, and pests), food preservation, selective killing of cells, etc. is carried out using high reactive PAW whereas low reactive PAW has applications in seeds germination, plant growth, and as a nitrogen source for agriculture and aquaculture applications, etc. In addition, the batch and continuous PAW production setup designs are scalable, therefore, can be used in industries for PAW production.
