Abstract
LA INVENCION SE REFIERE A UN SELECCIONADOR DE PRESION CON UNA CARCASA, QUE PRESENTA UNA FORMA CILINDRICA CIRCULAR O EN CORTE VERTICAL RESPECTO AL EJE CENTRAL DE LA MISMA UNA FORMA CIRCULAR, QUE DISPONE DE AL MENOS UN ORIFICIO DE ENTRADA Y UN ORIFICIO DE SALIDA, CON UNA DETERMINADA CAIDA DE PRESION POR MEDIO, UN FILTRO SIMETRICO ROTATIVO CON UN ROTOR Y ZONA DE SELECCION DE LA MATERIA, DISPUESTO CENTRADO EN EL INTERIOR DEL MISMO, PRESENTANDO EN EL EXTERIOR DEL FILTRO RADIALMENTE UNA ZONA DE MATERIAL ENTRE EL FILTRO Y LA CARCASA. LA INVENCION SE CARACTERIZA PORQUE EN SECCION EN PARALELO CON RESPECTO AL EJE CENTRAL DEL FILTRO, LA SECCION DE LA ZONA DEL MATERIAL SE HA AJUSTADO DE TAL FORMA AL FLUJO DE LA CORRESPONDIENTE MASA, QUE EL DESECHO ORIGINADO A CAUSA DE LA VELOCIDAD DEL FLUJO DE LA PRESION ESTATICA EN LA ZONA DEL MATERIAL ES SIEMPRE TAN PEQUEÑA, QUE EN BASE A LA DIFERENCIA DE PRESION ENTRE LA ZONA DE SELECCION DE LA MATERIA Y LA ZONA DEL MATERIAL, SE ORIGINAN VELOCIDADES DE FLUJO A TRAVES DE LOS ORIFICIOS DEL FILTRO EN CUALQUIER LUGAR DE UN MAXIMO DE 2,5 M/S, Y LA DESVIACION CON RELACION A VALORES MAS ALTOS (HACIA ARRIBA), ALCANZA DESDE UN MERO CALCULO RESPECTO A LA SUPERFICIE TOTAL DE PASO DEL FILTRO, UN VALOR MEDIO ARITMETICO DEL PERIMETRO TOTAL DEL FILTRO, COMO MAXIMO DEL 25 % DE ESTE VALOR.
