FLUIDIZED BED REACTION APPARATUS

摘要

PURPOSE:To prevent the outflow of a particulate material to the outside of a tank and to enhance efficiency, by providing an inclined partition wall in the tank and arranging a barrier plate below an opening part so as to be almost parallel to the partition wall to demarcate and form a solid-liquid two-phase part and a solid-gas-liquid three-phase fluidized part. CONSTITUTION:Bacteria or anzyme immobilized particles 11 formed by immobilizing bacteria or anzyme on solid particles subjected to the adhesion of bacteria or enzyme are received in a tank 3. A partition plate 4 inclined so as to form an opening part 14 between the lower end part thereof and the tank wall is provided to the upper part of the tank 3. A barrier plate 4' is arranged below the partition plate 4 almost in parallel to the partition plate 4 so as to cover the opening part 14 and particles flooded so as to follow air bubbles are guided to an obliquely upward direction along the barrier plate 4' to be separated from air bubbles and passed through the gap between the partition wall 4 and the barrier plate 4' to be flowed in a solid-liquid two-phase fluidized part 10. The particles are separated from a liquid to be refluxed to a three-phase fluidized part 9.
