Unit cell for aqueous alkali metal chloride electrolysis tank

摘要

Each of the unit cells for a plurality of bipolar filter press cells comprises an anode side pan frame having an anode chamber and an anode side gas-liquid separation chamber extending over its full length, and a cathode side pan frame having a cathode chamber and a cathode side gas-liquid separation chamber as well In the included unit cell, at least the anode side gas-liquid separation chamber has a porous segment containing bubble removing partition wall extending above the hole bottom wall and extending over the entire length of the vapor-liquid separation chamber, and the pore of the porous segment is the gas-liquid The gas-liquid separation chamber is provided with a first passage having a perforated area of the bottom wall of the hole, and a non porous region of the bottom wall of the bottom wall and gas and liquid by the bubble removing partition wall by the wall removing partition wall A unit cell is disclosed which is divided into a second passage leading to the discharge nozzle of the body.
