Fluidized bed reactor apparatus and a method for processing organic material using a fluidized bed reactor apparatus

A fluidized bed reactor apparatus, comprising:

• a cylindrical reactor chamber having a rotating shaft equipped with radially extending fluidization blades disposed in the reactor chamber, said rotating shaft is connected to a drive unit, one or more inlets for feeding fluidizing bed material into the reactor chamber, creating a fluidized bed in the reactor chamber, and for feeding organic material that shall be processed into the fluidized bed in the reactor chamber, and
• one or more outlets for discharge of material, gases and/or vapors from the reactor chamber, wherein the apparatus further comprises
• a mechanical separator chamber connected to the rotating shaft of the reactor chamber, said separator chamber being an apparatus for mechanical separation of dust particles in the gas and/or vapor stream received from the reactor chamber, and which comprises separation blades rotating around an axis of said rotating shaft, mechanically separating dust particles from the gas and/or vapor stream,
• a control system connected to the drive unit driving the rotating shaft, said control system being connected to sensors in the reactor chamber and in the mechanical separator chamber, and
• wherein said apparatus comprises sealing and support bearings at each end of the reactor chamber, said sealing and support bearings having inert gas flushing,
• wherein said apparatus comprises a polishing chamber connected to the mechanical separator chamber, said polishing chamber being an apparatus for removing particles in the gas and/or vapor stream received from the mechanical separator chamber, and
• said polishing chamber comprises a housing with an internal screw, forcing the gas and/or the vapor to follow the screw trajectory, and circulation means for circulating a cleansing fluid over surfaces in the polishing chamber.
