Filter-press type electrochemical reactor with bush inserts

Abstract

A Kit of modular components for the manufacture of an electrochemical reactor () of the so-called filter-press type having a substantially tubular body (), closed at the opposite ends by end plates () and in which is defined a sequence of electrolyte cells () in fluid with pipes (to) extended in said body (), in a direction parallel to its axis (AA), for the collection and distribution of process fluids, distinguishes itself in that it comprises: a plurality of electrochemically functional flat elements () selected from bipolar elements and separation elements, a plurality of frames (), all identical to each other, realized with an electrically non-conducting material and structured to enclose and support inside them, in a per se known way, respective pre-selected electrochemically functional flat elements (), each of the frames () being equipped with an equal plurality of through-holes () parallel to the axis of the respective frame () and equally angularly arranged between consecutive frames, each through-hole () being in fluid communication with the inside of the frame () through at least one passage (to) extended in the respective frame () in a substantially radial direction; a plurality of cylindrical bush inserts (), obtained with an electrically non-conducting material, capable of being coaxially engaged in each of the through-holes () in a pressurized fluid-tight arrangement, to hermetically close such at least one fluid communication passage (to) between the hole and the inside of the respective frame ().
