Antecedentes de la invención The main object of the present invention is a versatile plasma reactor, in discharge configuration, with dielectric barrier for treatments at adjustable pressure, from vacuum and reduced pressures to atmospheric pressure and higher pressures. Background of the invention
En los campos de la física y la química, se denomina plasma a un gas constituido por partículas cargadas y neutras (tales como electrones, iones y radicales libres) y cuya dinámica presenta efectos colectivos dominados por las interacciones electromagnéticas entre las mismas. Con frecuencia se habla del plasma como un estado de agregación de la materia con características propias, diferenciándolo de este modo del estado gaseoso, en el que no existen efectos colectivos importantes. In the fields of physics and chemistry, a gas consisting of charged and neutral particles (such as electrons, ions and free radicals) is called plasma and whose dynamics have collective effects dominated by electromagnetic interactions between them. Plasma is often referred to as a state of aggregation of matter with its own characteristics, thus differentiating it from the gaseous state, in which there are no significant collective effects.
Las aplicaciones del plasma son muy variadas y también ampliamente divulgadas. En la patente estadounidense 514,170 (“Incandescent Electric Light”, 6 de febrero de 1894), Nikola Tesla describe una lámpara de plasma. Esta patente es de una de las primeras lámparas de alta intensidad. Tesla tomó un tipo de esfera incandescente con el elemento conductor suspendido y le aplicó alto voltaje, creando así la descarga. Más tarde, Tesla llamaría a su invención “Inert Gas Discharge Tube”. Plasma applications are varied and also widely disclosed.
