MONODISPERSE PARTICLES PREPOLYMERISATION REACTOR

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of polymer pellets used in fabrication of ion-exchange resins. Reactor comprises housing with at least one inlet for feed of monodisperse particle emulsion in stabiliser water solution, outlet of emulsion containing monodisperse particles in elastic state arranged at housing bottom, stabiliser solution and emulsion mixer and pump. Said housing is composed of cylindrical vessel with conical cover with 60 degrees angle at vertex accommodating gland assembly of said mixer composed by pipe connected with reactor conical cover accommodating mixer shaft and two unions, one for stabiliser solution feed and one for venting. First union is located below the first one. Mixer shaft is arranged in said zone of gland assembly with clearance with gland assembly pipe. Said mixer is composed a low-rpm combined mixer arranged at upper two-thirds of the reactor and including three sets of mixing elements varying in shape and size arranged in different planes to allow soft mixing to preset drop sizes and mixing of bypass flows and dead zones. Mixer central shaft features diameter smaller than that of the first of downstream mixers compared to this of upstream one. Surfaces of the housing cover and mixer in contact with said suspension are made of anti-pickup drops. Heater maintains the reactor operating temperature.EFFECT: enhanced performances for phorpolimirisation.2 cl, 3 dwg
