Description
| - Článek popisuje vlastnosti speciálního typu plazmového reaktoru založeného na dielektrickém bariérovém výboji se zlepšenou homogenitou a stabilitou výboje. Výrazné zlepšení výbojových vlastností bylo dosaženo implementací porézní hydrofilní keramiky do oblasti mezi elektrodami. Tím mohla být redukována vzdálenost mezi aktivní elektrodou a povrchem kapaliny a bylo dosaženo přechodu od ?nitkovitého? k ?homogennímu? typu výboje. Dále bylo zjištěno, že systém může pracovat v širokém pásmu vodivostí a při zanedbatelném tepelném ovlivnění kapaliny. Rovněž byla měřena přítomnost ozonu a peroxidu vodíku v kapalině a byly provedeny testy na rozklad organického barviva. (cs)
- A system based on the dielectric barrier discharge (DBD) with improved discharge homogeneity, used for direct ozonization and purification of water, is presented here. A special design of the atmospheric DBD system is characterized by incorporation of a porous ceramic segment in the zone between electrodes. This porous segment was placed on the metallic electrode and served as a guide for flowing water. Due to the hydrophilic force it allowed the water to remain undisturbed by the electrical discharge. This feature enabled a reduction of the discharge gap and subsequently an increase in the intensity, stability and homogeneity of the discharge. It was observed that under such a configuration a transition from the filamentary mode to the semi-homogeneous mode of the plasma discharge could be realized. Discharge properties were investigated by the optical emission spectroscopy method and the results showed the domination of nitrogen lines in the UV-A region.
