FIELD: electrochemical reactors. SUBSTANCE: electrochemical reactor is designed for electrolysis of liquids to produce water and/or aqueous solutions with purposefully changed phycisochemical properties by electrochemical treatment. Continuous flow reactor has even number of diaphragm electrochemical cells connected with collectors for supply and discharge of treated liquid. Each collector is assembled from similar collector sections from dielectric material. Each section is made of two interpenetrating lengths of cylinders with large and small outer and inner diameters whose internal surfaces are communicated with each other. Axes of cylinders are perpendicular but not intersecting. Holes in end faces of small diameter cylinder are made in the form of sockets for attachment of pipe unions of electrochemical cells. Sections are connected to one another to form nipple joints. Devices are provided for fixation of sections relative to one another. The reactor features simplified design, reduced labor input for its mounting and dismantling and increased productivity. EFFECT: improved design and higher efficiency of reactor. 5 cl, 4 dwg
