Title
(EN) A HYDROCYCLONE WITH AN IMPROVED FLUID INJECTION MEMBER
(FR) HYDROCYCLONE DOTÉ D'UN ÉLÉMENT D'INJECTION DE FLUIDE AMÉLIORÉ
Abstract
(EN) A hydrocyclone having a mid-section having a longitudinal axis and a radius, and a fluid injection member releasably connected to the mid-section. The fluid injection member has a dilution passage therethrough and two spaced apart dilution ports, at least one dilution port being at an angle between 15 and 75 degrees relative to the mid-section radius. The injection member comprises a nozzle housing releasably connected to the mid-section, the nozzle housing having a dilution passage therethrough, and a nozzle adapted to be connected to the nozzle housing, the nozzle being planar and having at least one dilution port therethrough, the nozzle being receivable within the dilution passage.
(FR) Un hydrocyclone présentant une section médiane qui a un axe longitudinal et un rayon, et un élément d'injection de fluide relié de façon amovible à la section médiane. L'élément d'injection de fluide a un passage de dilution le traversant et deux orifices de dilution espacés, au moins un orifice de dilution étant à un angle compris entre 15 et 75 degrés par rapport au rayon de la section médiane. L'élément d'injection comprend un boîtier de buse relié de manière amovible à la section médiane, le boîtier de buse est doté d'un passage de dilution à travers ce dernier, et une buse conçue pour être reliée au boîtier de buse, la buse est plane et a au moins un orifice de dilution la traversant, et la buse peut être reçue à l'intérieur du passage de dilution.
