Abstract

LA INVENCION SE REFIERE A UN PROCESO Y A UN DISPOSITIVO DE MANUTENCION DE MATERIAL PULVERULENTO EN LECHO FLUIDIZADO QUE PERMITE DETECTAR Y PREVENIR EL TAPONAMIENTO DE LA PARED POROSA (4, 19, 21) DE FLUIDIZACION POR PRODUCTOS NO FLUIDIZABLES MEZCLADOS CON EL MATERIAL PULVERULENTO. CONSISTE EN DIVIDIR LA PARED POROSA EN DOS PARTES: LA PRIMERA (19) COLOCADA BAJO LA COLUMNA DE ALIMENTACION (15) ESTA SITUADA EN UN NIVEL HORIZONTAL INFERIOR AL DE LA SEGUNDA PARTE (21) COLOCADA BAJO LA COLUMNA DE EQUILIBRADO (16), CADA UNA DE ESTAS PARTES ESTA ALIMENTADA POR DOS VOLUMENES INDEPENDIENTES (18, 20) Y SE MIDE LA DIFERENCIA DE PRESION DE FLUIDIZACION EN CADA UNO DE ESTOS DOS VOLUMENES. ESTA DIFERENCIA AUMENTA EN FUNCION DEL TAPONAMIENTO DE LA PARED POROSA (19) COLOCADA BAJO LA COLUMNA DE ALIMENTACION Y PERMITE UN DESTAPONAMIENTO DE ESTA PARED CUANDO LA DIFERENCIA SOBREPASA UN VALOR DE REFERENCIA. LA INVENCION SE APLICA AL TRANSPORTE EN LECHO FLUIDIZADO DE CUALQUIER PRODUCTO: ALUMINA, CAL, CEMENTO, POLVO METALICOS Y PLASTICOS, PRODUCTOS ALIMENTICIOS.
