摘要： The invention concerns an electrolysis apparatus for producing halogen gases from an aqueous alkaline halide solution with a plurality of plate-like electrolysis cells which are disposed adjacent one another in a stack, are in electrical contact, and each comprise a housing consisting of two half-shells of electrically conductive material with outer contact strips on at least one housing rear wall. The anode and the cathode are separated from each other by a partition wall, are disposed parallel to one another and are connected in an electrically conductive manner to the respective associated rear wall of the housing by means of metal reinforcements. The object of the invention is for the surfaces through which current flows to be as large as possible so as to prevent non-uniform current distribution. To that end, the metal reinforcements take the form of webs (10) which are aligned with the contact strips (7) and whose side edges (10A, 10B) abut the rear wall (3A, 4A) and the anode (8) and cathode (9) over the height of the rear wall (3A, 4A) and the anode (8) and cathode (9).

摘要： The invention relates to an electrolysis apparatus for producing halogen gases from an aqueous alkali halogen solution, comprising several electrically connected plate-shaped electrolysis cells arranged in a pile and respectively provided with a housing consisting of two half shells made of an electro-conductive material and fitted with outer contact strips on at least one rear wall of said housing, also including two respective planar electrodes (anode and cathode), whereby the anode and cathode are provided with louver-like orifices so that the electrolytic feed material and products can flow though, said anode and cathode are separated from each other by means of a partition wall, are arranged parallel to each other and are electroconductively connected to the associated rear wall of the housing by means of metal reinforcements. The aim of the invention is to provide an apparatus which can operate at flow densities of more than 4 kA/m with correspondingly higher production of gas in the boundary layer while maintaining a sustainable service life for the membrane and requiring few pulses. This is achieved by slanting the louver-like orifices (8B, 9B) of the anode (8) and cathode (9) towards the horizontal.

摘要： The invention relates to an electrolysis device to carry out electrochemical processes, comprising at least one plate-like electrolysis cell with a housing . Said housing is provided with devices to feed the electrolysis current and electrolysis input materials and with devices for discharging the electrolysis current and electrolysis products in addition to an anode and cathode. The anode and cathode are separated from each other by means of a partition wall and are electroconductively connected to the respective allocated rear wall of the housing. The aim of the invention is to provide a solution to prevent the formation of foam using the simplest means possible. This is achieved by providing the housing (3,4) of each electrolysis cell with hydrophobic fittings (12) in at least one of the halves of the housing defined by the partition wall (6).
