Abstract

The invention which discloses a membrane polar distance repolarization natural cyclic ionic membrane electrolytic tank relates to an electrolytic device used in chlor-alkali industry and aims at solving the problem that the tank voltage is influenced by the solution voltage drop existing among the electrodes in the prior art. The invention mainly consists of unit electrolytic tanks (2), an end part semi-unit electrolytic tank and a sealing pad and ionic membranes (3) which are positioned between the unit electrolytic tanks; the invention has the design points that a support net (11) of a cathode side is welded on a cathode plate (9) to form a cathode chamber through a cathode side gluten plate (10); the cathode side of the unit electrolytic tank also comprises a cathode net (13) and an elastic net (12) which is welded on the support net of the cathode side while the cathode net is arranged outside the elastic net and a sealing surface of a frame is lapped and fixed around the cathode net; the ionic membranes of and among all unit electrolytic tanks are serially connected through a side rod (1) of an extruder and the cathode, the ionic membranes and the anode are closely connected. The ionic membrane electrolytic tank has the advantages of more stable running, great resistance to positive-negative pressure difference, low voltage and low electricity consumption.

Description

technical field [0001] The invention relates to an electrolytic device used in the chlor-alkali industry, in particular to a membrane pole-distance double-pole type natural circulation ion membrane electrolyzer. Background technique [0002] The existing bipolar natural circulation ionic membrane electrolyzer is mainly composed of a plurality of unit electrolyzers, and the ionic membrane is sealed by a gasket between the unit electrolyzers, and the unit electrolyzers are arranged back to back and connected on the conductive path Disc and anode disc, a frame composed of four frames, cathode and anode welded to the cathode and anode discs through conductive ribs, and a gas-liquid separation box on the upper part of the cathode and anode chambers. The cathode disc and anode disc are surrounded by belts. The disc-shaped member of the side wall has an inlet for the electrolysis material to enter and an outlet for the electrolysis product to flow out on the side walls of the catho...
