Apparatus for effecting operacaoes fluidizadas

摘要

IMPROVEMENT IN FLUIDIZED RED APPARATUS Apparatus for carrying out fluidized operations comprising an elongate generally upstanding housing, said housing defining and upper chamber, an intermediate chamber and a lower chamber. A plurality of open ended tubes is positioned inside the intermediate chamber. The open ends of each of said tubes communicates the interior of said tubes with the upper and lower chambers. An improved spacing means is provided in the upper chamber, said spacing means having a plurality of tapered openings wherein said openings are coterminous on the upper surface of said spacing means and spaced on the lower surface of said spacing means. The openings on the lower surface are in concentric communication with the open ends of said tubes in the upper chamber, thereby communicating the interior of said tubes with the upper chamber. The improved spacing means prevents the formation or "dead zones" where solids may lay for extended periods and be subjected to high temperatures and danger of explosion.
