ABSTRACT:
This invention provides a fluidized bed reactor with improved method and apparatus for inhibiting and clearing clogging of the fluid distribution network in such reactor. In particular, at least one channel or reservoir of fluid is provided over at least a selected portion of the distribution network, with fluid from such column/reserve being released to maintain flow and pressure in the distribution network as the media bed is defluidized. For the preferred embodiment, the fluid column is (a) a feed pipe connecting a fluid inlet which is above the reactor fluid level to the distribution network; and (b) a plurality of risers which, for the preferred embodiment, extend from the end of each lateral tube of the distribution network. A vacuum breaker is provided for each fluid column to permit fluid to flow from the column into the network when pressure is removed. A valve controlled opening may be provided at the top of each riser to permit purging of the distribution network through the openings when the valve is opened and to provide access to the distribution network for clearing clogs without requiring removal of the media bed.
