INSTALLATION AND METHOD FOR EFFICIENT PRODUCTION OF STRUCTURED ATTACHMENT ELEMENT WITH INTERSECTING CHANNELS Russian patent published in 2023 - IPC B01J19/32 

FIELD: construction.

SUBSTANCE: group of inventions is related to an installation and method for the production of a structured attachment element with intersecting channels for a column designed to carry out mass transfer and/or heat exchange between a heavy fluid phase and a light fluid phase. Moreover, the structured attachment element with intersecting channels contains at least two adjacent layers made of sheets of expanded metal, each of which has holes that are surrounded and separated from each other by separating elements, and containing periodic deformations. At least two of at least two layers are located in the longitudinal direction of the attachment element parallel and in contact with each other so that an open space is formed between them, extending from one end to the opposite end of at least two layers, along which can at least one of the heavy and light fluid phases must occur. Moreover, the installation contains: a) a stretching machine for cutting and stretching a metal sheet to produce an expanded metal sheet, b) optionally, a calibration machine for rolling an expanded metal sheet made in a stretching machine to a given thickness, c) a block for storing the sheet, d) a forming machine for shaping an expanded metal sheet made in a stretching machine and optionally rolled in an optional sizing machine to produce an expanded metal sheet having periodic deformations, and e) a laying machine for laying the expanded metal sheets drawing metal, having periodic deformations, to obtain a structured attachment element with intersecting channels. In addition, the sheet storage unit is configured to directly receive the expanded metal sheet produced in the stretching machine and optionally rolled in the optional sizing machine, and dispense the expanded metal sheet directly to the forming machine.

EFFECT: enabling winding of an expanded metal sheet without causing stress and/or without applying pressure to the sheet without deforming the sheet.
