    摘要： A spouted bed electrochemical reator (100) for treating a plurality of objects (114) with a fluid is set forth. The apparatus comprises a vessel (119) for contacting the plurality of objects (114). An upwardly directed stream of fluid and a portion of the objects are confined in a conduit (116) such that the fluid stram causes the objects to flow upward from a moving bed (124) thereof to a disengaging position from where they fall onto a distritution shield (123) and move downward to a feed position. The vessel (119) may be used for treating electrically conductive objects wherein the fluid is an electrolyte, an electrode is positioned to contact the moving bed, and a counterelectrode (105) is positioned in spaced relation to the moving bed. The vessel may be fixed or portable.

    摘要： A method for converting an electrorefinery comprises the steps of:

    (a) short-circuiting a first section in an electrical circuit of an electrorefining unit and meanwhile:

    removing all electrode sets arranged for operation at a cathode spacing d1 from the electrorefining cells in the section;
    installing electrode sets with a cathode spacing d2 in the cells in the section, except the first and last cells;
    installing in the first and last cells in the section a cell bypassing device so as to bypass the first and last cells;

    (b) after step (a), opening the short-circuit to allow current to circulate through the section again;
    (c) repeating steps (a) and (b) for each of the remaining sections in the unit; and
    (d) interrupting the power supply in the electrical circuit and meanwhile replacing all head-bars configured for operating at cathode spacing d1 by head-bars configured for operating at cathode spacing d2.

    A cell bypassing device is also presented.

    摘要： An arrangement for cleaning the bottom (5) of an electrolytic tank (1) of solids (6) settled on the bottom of the tank, said arrangement comprising elements to be moved along the bottom or at least in the vicinity thereof in order to detach solids from the bottom. The arrangement comprises at least one moveable suction element (11), whereby at least part of the solids (6) accumulated on the bottom (5) is conducted out of the tank (1).
