ABSTRACT:
Replaceable outer support structure38for a particulate material bed70in a radial flow system comprises a plurality of hollow conduits50, 250, 260, at least some of which have a generally trapezoidal cross-section. The conduits are arranged in a ring around the inside wall surface39of the vessel42and have flat or slightly concave inner wall surfaces52formed of segments of vertically extending screen members which have slots or openings86which provide uniform flow through the uniform thickness particulate bed which they help define The side walls54, 56of the conduits extend generally radially outwardly to engage the inner surface39of the outside wall40of the vessel and at least those of them which have a trapezoidal cross-section have their side walls formed at an included angle α which is less than if they extended radially relative to the axis of the vessel. An embodiment having alternating generally trapezoidal250and generally rectangular cross-sections260for the conduit members maximizes the total internal flow area of the ring of conduits as compared to an embodiment in which all of the conduit members have a trapezoidal shape, while still allowing the inward movement of individual conduit members during installation or replacement operations.
