Abstract

UN METODO Y UN APARATO PARA LIMPIAR LOS FILTROS (3, 3A, 3B) CONTAMINADOS POR RESINAS DE FUSION EN CALIENTE Y POLIMEROS IN SITU SIN QUITAR LOS ELEMENTOS DE FILTRADO. EL METODO COMPRENDE UN PASO PRELIMINAR DURANTE EL QUE SE INTERRUMPE LA CIRCULACION DEL PRODUCTO QUE SE VA A FILTRAR POR EL FILTRO QUE SE VA A LIMPIAR, Y UN PASO DE DRENAJE, DURANTE EL QUE UN FLUIDO DE DRENAJE PRESURIZADO ES PASADO POR EL FILTRO (3, 3A, 3B) PARA VACIAR EL FILTRO DE PRODUCTOS RESIDUALES. DESPUES, SE LLEVA A CABO UN PASO DE LIMPIEZA DEL FILTRO DURANTE EL QUE UN FLUIDO DE LIMPIEZA, CONSTITUIDO AL MENOS PARCIALMENTE POR VAPOR SUPERCALIENTE, ES PASADO POR EL FILTRO. LOS FLUIDOS UTILIZADOS PARA LIMPIAR EL FILTRO SON DESPUES SOMETIDOS A TRATAMIENTOS PARA ELIMINAR LOS AGENTES CONTAMINANTES.
