Description

1 The invention relates to the technology of electrochemical production of fluorine. A known cell for the production of fluorine, comprising a housing, a crib, steel cathodes, and carbon-graphite anodes, mounted in a vertical position in current leads inserted into the bodies of the anodes parallel to the longitudinal axis of the anodes and passing through the gland seals in the bottom or bottom of the electrolyzer. The disadvantages of the known electrolyzer are the impossibility of accurate installation of anodes with respect to cathodes and bells to collect fluorine, which leads to a reduction in the time between repairs of the electrolyzer, a decrease in current efficiency and does not allow an increase in electrolysis power by increasing the anodic current density More than 0 , 2 a / ohm) 1 In order to eliminate the indicated drawbacks, electrolytic was proposed. The core, in which each anode is fixed horizontally in the current leads sealed in the body of the electrolyzer and introduced into the electrolyzer from opposite sides, the gland seals are made in the form of sets of rubber rings filled with fluorspar. Fig, presents the described electrolyzer, front view; on §ig.2 - the same, section along aa and ai. I, The electrolyzer consists of a rectangular I-shaped housing made of sheet steel and a cover 2. Electrodes are mounted in the housing: anodes 3 and cathodes 4 of louvre type. Between the cathodes a cooling system (heating) 5 of the electrolyzer is placed. The current leads are made in the form of copper rods, 6, screwed into both end parts of the anode. Copper rods are protected from electrolyte exposure by magnesium covers.

7c, to ensure that the anode is eroded, a shaped sleeve 8 made of dielectric material of a heat-resistant fluoroplast is connected from the housing.

The electrolysis of the electrolyzer makes it possible to increase the accuracy of the installation of the anodes relative to the cathodes of the gas separation bell, which increases the fluorine yield due to the fusion installation of the anodes in the housing eliminating electrode electrodes and increasing the durability of the electrolyzer

The introduction of current leads 6 into the bodies of the anodes 3 from two opposite sides allows increasing the current load on the electrode or reducing the overheating of the contact zone and thereby increasing the durability of the electrode. The 11th 5e1sh of the designs of the electrolyzer also allows, with the conservation of the research institute the diameter of the current-carrying rod, to use a material with a lower electrical conductivity but more readily available in the process.
