Apparatus for gas-solid fluidization systems with improved stripping

摘要

An apparatus for intimate mixing of solid particles and gas media in a gas-solid fluidized bed is disclosed. The device comprises a plurality of corrugated and / or corrugated planar columns arranged between alternating intersecting planar columns or at alternating intersecting surfaces providing a plurality of adjacent open spaces. The element has a three-dimensional grid configuration and corrugated and / or corrugated planar columns are formed of metal with peaks and valleys or valleys, such that when the peaks and valleys or valleys are assembled to the element, 90 degrees from the descending line of the planar column Tilted below. Tilted peaks and valleys or valleys form channels that enhance the lateral movement of the catalyst particles into the space between the columns, providing improved vapor / solid mixing and contact.
