Abstract

JIMENEZ-AVILES, Gerardo et al. Control of a Dielectric Barrier Discharge Reactor based on Graphical System Design. Ing. invest. y tecnol. [online]. 2017, vol.18, n.1, pp.17-29. ISSN 1405-7743.

This paper describes the development and implementation of a control and monitoring system for the physical parameters involved in the stages of initiation, maintenance and shutdown of dielectric barrier discharges generated within a coaxial geometry reactor. In the process, the graphical system design (GSD) was employed to efficiently combine a graphical user interface (GUI), the data acquisition card DAQ-6259 with USB communication channel, a switch-mode power supply in push-pull configuration, drivers for gas flow, chemical and electronic equipment for diagnosis. The core of the GSD approach is located in the G code from LabVIEW ™, in this way, accurate data was collected in real time (e.g., airflow and power applied), which allowed to perform an analysis of the discharges performance. During testing, different concentrations of a mixture of helium contaminated with nitrogen oxides, in order to quantify the percentage of its degradation. The results indicate a value greater than 88%. For safety reasons, the GUI can be accessed remotely through institutional intranet, because of the generated compounds that may represent a risk to human health.

Keywords : atmospheric pollution; dielectric barrier discharges; graphical system design; mobile sources; nitrogen oxides; cold plasma.
