Patent ID: 10155680

Abstract:
Apparatus for treating a fluid, which comprises a plurality of superimposed cells that are assembled and compressed together to form a stack by fixing means. Each cell comprises at least one chamber delimited by two facing containment layers and provided with an inlet opening and with an outlet opening for the passage of a fluid to be treated. Each chamber perimetrically arranges first sealing means for sealing it with fluid seal and houses at least one electrode layer for treating the fluid. According to the invention, each chamber comprise at least two support layers, e.g. rigid, made of plastic material, each of which being mechanically fixed to one of the two containment layers advantageously formed by the same electrode layers. Hence, first spacer means are provided, interposed between the two support layers of each cell in order to separate, by a first compression end stop distance, the two containment layers of the chamber and prevent excessive compressions of the layers of the cell while ensuring optimal hydraulic seal; and second spacer means are provided, interposed between the support layers of pairs of contiguous cells in order to separate them at a second compression end stop distance aimed to ensure the hydraulic connection between the cells without subjecting the same cells to an excessive compression which varies the internal size thereof in an imprecise manner.
