Abstract
Abstract A reactant element for contacting a stream of fluid such as air or other gas or liquid with a particulate reactant. The particulate reaction is retained in a core structure specially constructed to resist deflection by fluid moving through the element. The core structure consists of two sets of parallel stiffening strips transversely disposed across a moving fluid stream. One of the sets of parallel strips is rotationally displaced from the other such that the strips of one set lie in planes angularly displaced from the planes of the first set of strips. Corrugated spacer sheets are disposed between the strips of each set and are joined at the tops and bottoms of the corrugations to the next-adjacent strips. A particulate reactant material is disposed in the fluid channels formed by the spacer sheets and the stiffening strips. A frame encloses the periphery of the core structure, forming a unitary cartridge-like element.

An improved cartridge element for fluid treating apparatus, specially adapted to resist deflection by fluid moving therethrough, said element comprising: a. a first core member, including i. a plurality of spaced parallel transverse planar stiffening strips disposed in planes generally parallel to the direction of fluid flow, and ii. corrugated spacer sheets disposed between and joined at the tops and bottoms of corrugations thereof to adjacent stiffening strips, forming a plurality of parallel fluid channels extending generally in the direction of fluid flow; b. a second identical core member disposed in parallel relation to said first core member and rotationally angularly displaced therefrom to the stiffening strips of said second core member lying in planes rotationally angularly displaced from the planes of the stiffening strips of said first core member; c. solid particulate material disposed in and substantially filling said fluid channels; d. porous sheet means disposed against the upstream and downstream faces of said elements covering the upstream and downstream openings of said parallel fluid channcels to retain the solid particulate material therein; and e. frame means enclosing the periphery of said core members and sheet means forming a unitary cartridge element.
