Novel INEOS membrane polar distance electrolytic cell

Abstract

The invention relates to a novel INEOS membrane polar distance electrolytic cell. The electrolytic cell comprises an anode unit, a cathode unit and ion membranes positioned between the anode unit andthe cathode unit. The electrolytic cell is characterized in that the anode unit comprises anode unit cell bodies, and a new anode net is arranged on the left side face of each anode elastic claw, wherein each new anode net is a complete net; the cathode unit comprises cathode unit cell bodies, each cathode column is provided with a cathode elastic claw on the right, the right side face of each cathode elastic claw is provided with an original cathode net, and the right side face of each original cathode net is provided with an elastomer; a new cathode net is arranged on the right side face ofeach elastomer, and each ion membrane is arranged between the corresponding new cathode net and corresponding new anode net of the same unit cell group. The novel INEOS membrane polar distance electrolytic cell has the advantages of being capable of reducing overvoltage, reducing damage of the ion membranes, providing convenience for replacing cathode and anode nets in the later period and increasing the effective electrolytic area, and reliable and safe during running.

Description

technical field [0001] The invention relates to a novel INEOS membrane pole distance electrolyzer. Background technique [0002] The INEOS electrolytic cell is produced in the UK. There are 128 pillars and elastic claws distributed in the cathode and anode unit tanks. The electrodes (cathode and anode) are on the top. The electrodes above the pillars have holes, and pins are installed in the mesh. The pins are metal. Titanium, nickel plus fluorine plastic cap, (such as figure 1 shown). A layer of ionic membrane is sandwiched between an anode unit and a cathode unit. There are rubber gaskets on the sealing surfaces of the cathode and anode respectively, and there are flange frame bars on the back, which are locked by screw groups (76 groups) to form a Group cell slots, (eg figure 2 shown). Multiple sets of unit tanks are suspended on the tank frame, one side leans against the fixed wallboard, and the other side is tightened by 32 sets of ejector bolts, and the current co...

[0005] 2. The cathode and anode pins will partially squeeze the ion membrane, and the 128 pins also waste the effective area of ​​electrolysis π*(25 / 2) 2 *128=62800mm 2 =0.0628m 2

[0006] On this basis, titanium-based ruthenium-titanium coatings are generally used for the anode coating of traditional electrolytic cells. However, the titanium-based ruthenium-titanium coatings have been tested in production practice and found that their defects are: the electrode life is short, and the oxygen content in the produced chlorine gas The content is too high, which affects the purity of chlorine gas and causes a decrease in current efficiency
