    摘要： Vertically oriented cathode grids or cathode plates, adjacently situated at closely spaced intervals in a cathode box, are cleaned by spraying jets of liquid onto the cathode surfaces at an angle of about 10.degree.-50.degree. and at a pressure of about 60 to 140 atmospheres, while moving the liquid jets uniformly along the cathode surfaces. A device for performing this process comprises a bar shaped spraying means comprising spraying nozzles which are connected to pressure resistent feeding means for the liquid. The spraying means is connected to a guiding system comprising a bar shaped first guiding means, a second guiding means including a guiding bar and a guiding cylinder and a third guiding means and moving means mounted on a support which can be moved over the cathode box and which further comprises means for aligning the guiding system and the spraying means to the cathode box in such a way that the spraying means can be moved uniformly along the cathode surfaces by means of the guiding means and the moving means.
