Abstract

A találmány tárgya elektrolizáló cella, eljárás vizes oldatoktisztítására, valamint eljárás kemikáliák szintetizálására. Aszennyezett vizes oldatokat, így talajvizet és ipari üzemekből, mintpapírgyárakból, élelmiszer-feldolgozó üzemekből és textilgyárakbólszármazó szennyvizeket könnyen lehet tisztítani, színteleníteni ésfertőtleníteni a találmány szerinti tökéletesített, gazdaságosabb,nyitott elrendezésű elektrolizáló cellában, amelyben az elektródoktöbb, egymással villamosan érintkező porózus elemből állnak. A celláklehetnek osztottak vagy osztatlanok, és köthető monopoláris vagybipoláris elrendezésbe. Nagyon szűk elektródközi rések eseténszavatolva van a gazdaságos működés, különösen akkor, ha viszonylagkis vezetőképességű oldatokat kell kezelni. Az újszerű cellakemikáliák, mind szerves, mind szervetlen típusú kemikáliák, ígyhipoklorit fehérítőszerek és más oxigénezett anyagok elektromosszintetizálására is alkalmazható. ÓThe subject of the invention is an electrolyzing cell, a process for purifying aqueous solutions, and a process for synthesizing chemicals. Contaminated aqueous solutions, such as ground water and waste water from industrial plants such as paper mills, food processing plants and textile factories, can be easily cleaned, decolorized and disinfected in the improved, more economical, open layout electrolyzing cell according to the invention, in which the electrodes consist of several porous elements in electrical contact with each other. Cells can be divided or undivided and can be connected in a monopolar or bipolar arrangement. In the case of very narrow inter-electrode gaps, economical operation is guaranteed, especially when solutions with relatively low conductivity have to be handled. It can also be used to electrosynthesize novel cell chemicals, both organic and inorganic types of chemicals, such as hypochlorite bleaches and other oxygenated substances. HE
