Abstract
El concepto es aplicable a ciclones dispuestos en serie que operan bajo condiciones en las cuales la presión en la parte superior de un tubo descendente inferior de ciclón es menor que la presión externa donde se recoge y descarga el material en forma de partículas finas. Un dispositivo de terminación de tubo descendente inferior de ciclón de segunda etapa opera en un recipiente separador (2) o en un recipiente del regenerador de un convertidor de craqueo catalítico de fase fluida (FCC) con la capacidad de invertir las condiciones de presión que se presentan comúnmente en este tipo de equipo. Un extremo del tubo descendente inferior (7) del ciclón es unido a un recipiente recolector (11), de tal manera que una porción del tubo descendente inferior (7) entra dentro del recipiente recolector (11). El extremo del tubo descendente inferior (7) del ciclón está conectado a un dispositivo obturador convencional (17). El recipiente recolector (11) presenta por su fondo una salida en forma de un tubo descendente interior (14), en cuya parte inferior se ha introducido un dispositivo inyector (16) a través del cual se descarga un fluido a alta presión, asociado con una tobera de tipo "venturi" (15), la cual desplaza o arrastra al material en forma de partículas descargado por el tubo descendente inferior (7) del ciclón (4) a través de las válvulas obturadoras (17), dentro del recipiente recolector (11) hacia el exterior del recipiente recolector (11).The concept is applicable to cyclones arranged in series that operate under conditions in which the pressure at the top of a lower descending cyclone tube is less than the external pressure where the material is collected and discharged in the form of fine particles. A second stage lower cyclone down-tube termination device operates in a separator vessel (2) or in a regenerator vessel of a fluid phase catalytic cracking converter (FCC) with the ability to reverse the pressure conditions that are They commonly present in this type of equipment. One end of the lower down tube (7) of the cyclone is attached to a collecting container (11), such that a portion of the lower down tube (7) enters into the collecting container (11). The end of the lower descending tube (7) of the cyclone is connected to a conventional sealing device (17). The collection vessel (11) has at its bottom an outlet in the form of an inner descending tube (14), in whose lower part an injector device (16) has been introduced through which a high pressure fluid is discharged, associated with a "venturi" type nozzle (15), which displaces or draws the particulate material discharged by the lower descending tube (7) of the cyclone (4) through the shut-off valves (17), into the collection vessel (11) towards the outside of the collection container (11).
