Title:
FLUID BED REACTION DEVICE SYSTEM
Document Type and Number:
Japanese Patent JPS55152540
Kind Code:
A
Abstract:
A fluidized bed reactor system comprises a vessel (10) adapted to contain a fluidized bed, a plurality of fluid injector means (24) mounted through the vessel wall (20) for injecting and distributing a fluidizing medium into the lower portion of the vessel, each injector means being made up of an elongated injector having a nozzle end (26) projecting into the vessel. The injector is withdrawably mounted through the vessel wall and has at least one downwardly directed orifice (28). Shield means (32) are provided which are mounted on the vessel wall above the injector extending along the length of the injector for maintaining an opening in the bed when the injector is withdrawn. The opening is substantially equivalent to the length of the injector. The reactor system further includes fluid supply means (48) in fluid communication with each elongated injector (24) for supplying the fluidizing medium to each nozzle end (26). When it is required to replace the injector due, for example, to clogging of the orifices or deterioration, the injector is withdrawn from the vessel, replaced or repaired and then inserted into the vessel, The shield means allows for the easy insertion of the injector into the vessel by maintaining an opening in the bed, whether fluidized or non-fluidized. The fluidized bed reactor system allows for the replacement or repair of injectors without the necessity for shutting down and/or cleaning out the vessel.
