Abstract
Un procedimiento de tratamiento a distancia por plasma de materiales particulados, que comprende: la mezcla de un flujo (23) de gas del procedimiento y de un flujo (24) de gas portador en la zona (3) de tratamiento, en el que, antes de la mezcla, el flujo (23) del gas del procedimiento es enriquecido por especies de gas excitadas y el flujo (24) del gas portador es cargado con las partículas del sustrato; en el que una descarga eléctrica del gas es aplicada al flujo (23) del gas del procedimiento para la creación de un plasma no térmico a la presión atmosférica, o cerca de la misma, cuyos electrones son utilizados para generar especies activas en el flujo (23) del gas del procedimiento, y en el que las altas velocidades son superpuestas al flujo (23) del gas del procedimiento prolongando la distancia de desplazamiento de las especies excitadas y, de esta manera, ampliando la región de posluminiscencia de dicho plasma atmosférico; en el que la zona / fase del tratamiento de las partículas del sustrato dentro de la zona (3) de tratamiento es espacial y temporalmente separada de la producción de dichas especies excitadas, de manera que la zona (3) de tratamiento y / o la fase de tratamiento es situada en la posluminiscencia del plasma no térmico o corriente abajo de esta región; y en el que tiene lugar una reacción homogénea, química de las especies excitadas sobre la superficie de las partículas del sustrato en dicha zona (3) de tratamiento, caracterizado porque en la zona (3) de tratamiento el flujo (24) del gas portador cargado con partículas es guiado a lo largo de un eje geométrico (30), y porque el flujo (23) del gas del procedimiento enriquecido con las especies excitadas es guiado hasta la zona (3) de tratamiento desde una dirección esencialmente perpendicular a dicho eje geométrico (30) o en una dirección cónica, de manera convergente en el que el flujo (23) del gas del procedimiento es guiado a la zona de tratamiento a través de al menos un canal (28) situado en un plano perpendicular a dicho eje geométrico (30).
