CONVERTER FOR CONVERTING SO INTO SO Russian patent published in 2020 - IPC C01B17/80 B01D53/86 B01D53/88 B01J8/04 B01J8/00 

FIELD: machine building.

SUBSTANCE: to reduce mechanical load on casing and/or central pipe of mesh shelf of contact device invention provides segment for formation of membrane plate for contact device, in particular, for oxidation of SO₂ in SO₃, wherein, when viewed from above, segment has a projection surface parallel to longitudinal axis L, which is a cut from circular ring about centre M, longitudinal axis L passes through centre M, segment has inner edge facing the centre, radial - if seen from the centre - the outer edge opposite to the inner edge and two side edges, at that the lateral edges are limited from the side in the radial direction - if viewed from the centre - from the inner edge to the external edge, the projection surface of the segment.

EFFECT: such a partially non-fixed segment made according to the invention makes it possible to create a membrane plate such that during operation the forces acting on the membrane plate will not load tensile beam in the direction towards the periphery of tension, as well as the converter casing and the central pipe of the converter by radial forces, for which calculation of strength for longitudinal bending is required, and simultaneously the T-beam is in the catalyst mass to reduce the height of the converter.
