ABSTRACT:
A Kit of modular components for the manufacture of an electrochemical reactor (1) of the so-called filter-press type having a substantially tubular body (1a), closed at the opposite ends by end plates (2, 3) and in which is defined a sequence of electrolyte cells (4z,4b) in fluid with pipes (7to10) extended in said body (1a), 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 (13, 13a) selected from bipolar elements and separation elements, a plurality of frames (11), 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 (13, 13a), each of the frames (11) being equipped with an equal plurality of through-holes (14, 14a; 15, 15a; 211, 22; 26, 27) parallel to the axis of the respective frame (11) and equally angularly arranged between consecutive frames, each through-hole (14, 14a; 15, 15a; 21, 22; 26, 27) being in fluid communication with the inside of the frame (11) through at least one passage (16to19) extended in the respective frame (11) in a substantially radial direction; a plurality of cylindrical bush inserts (25), obtained with an electrically non-conducting material, capable of being coaxially engaged in each of the through-holes (14, 14a; 15, 15a; 21, 22; 26, 27) in a pressurized fluid-tight arrangement, to hermetically close such at least one fluid communication passage (16to19) between the hole and the inside of the respective frame (11).
