Problems solved by technology

[0006] However, in the existing membrane electrode distance sub-membrane electrolyzer structure, a wire mesh made of round nickel wire is used, such as figure 1 As shown, the silk screen is pressed into a corrugated shape to achieve the purpose of elasticity. The elastic net made by this method has a small conductive contact area and weak elasticity, and it cannot recover after being squeezed by external pressure.

Abstract

The invention discloses an elastic electrode in an ionic membrane electrolytic bath. The electrolytic bath comprises cathode screens and anode screens which are oppositely and parallelly arranged at intervals; the cathode screens and / or the anode screens are provided with ionic membranes; the cathode screens are connected on a bracket; an accommodating cavity is formed between the cathode screens and the bracket; a helical spring type elastic screen is arranged in the cavity; the elastic screen is formed by winding a tape-shaped nickel foil; and the outer side of the elastic screen is connected with the cathode screens and the bracket respectively. The elastic electrode in the ionic membrane electrolytic bath has uniform conductivity, uniform elasticity and high durability, and can be suitable for ionic membrane electrolytic baths with different electrode distances or membrane polar distances.

Description

technical field [0001] The invention relates to an internal structure of an electrolytic cell, in particular to an elastic electrode in an ion membrane electrolytic cell. Background technique [0002] The ionic membrane electrolyzer is a method in which the unit electrolyzer is divided into an anode chamber and a cathode chamber by using a cation exchange membrane to separate the electrolytic products. Ion-membrane electrolysis is a new technology developed on the basis of ion-exchange resin or ion-exchanger. The ion-exchange membrane has selective permeation characteristics for anions and cations, allowing ions with one charge to pass through and restricting ions with the opposite charge to pass through, so as to achieve the purpose of concentration, desalination, purification, purification and electrochemical synthesis. [0003] This technology has been used in the production of chlor-alkali, the desalination of seawater and brackish water, the preparation of industrial w...
