Abstract
The utility model relates to a membrane polar distance ion membrane electrolysis bath, which comprises a cathode disc (1) and a cathode net (3) and is characterized in that a nickel plate strip (2) is arranged between the cathode disc (1) and the cathode net (3), an elastic net (4), a covering net (5) and a cathode active net (6) are sequentially arranged on the cathode net (3), the bottom surface of the elastic net (4) is welded with the cathode net (3), the edge of the covering net (5) is welded with the cathode net (3), and the edge of the cathode active net (6) is welded with the edge of the sealing surface of the cathode disc (1) through a nickel belt. The membrane polar distance ion membrane electrolysis bath has the advantages that because the cathode net and an ion membrane are flexibly pasted through the elastic net, the membrane polar distance is realized, and the energy saving effect is reached; and the cathode net is changed into a nickel wire woven net from an original pull-hole net, and the electrolysis specific surface area is increased, so the current distribution is uniform, the bath voltage is dropped, the electrolysis efficiency is improved, and the energy saving effect is obvious.
Description
Technical field
The utility model relates to a kind of ion-exchange membrane electrolyzer, relates in particular to a kind of film pole span ion-exchange membrane electrolyzer, belongs to technical filed of chlor-alkali equipment.
Background technology
Ion-exchange membrane electrolyzer makes the chlorine industry specific equipment, and its effect makes through electrolytic brine and produces caustic soda and chlorine.Chlorine industry is as the highly energy-consuming industry, and save energy is raised the efficiency, and employing new technology energy-saving and cost-reducing with advanced and applicable technology is Eternal Theme.Japan's chlorine engineering BiTAC cell construction is followed successively by anode network, anode disc, cathode disc, spring piece and cathode screen from the bottom up.Phenomenons such as following deficiency is arranged during design: 1, the negative and positive polar net is thickness 1mm sheet material pulling eye net, and the pit that wire side forms because of resistance welding and spring piece elasticity are inhomogeneous make and have only part and ionic membrane applying between the negative and positive polar net, or do not fit, the generation pole span; 2, the conduction point of contact of cathode screen and spring piece is less, and only about 640, the cathodic activity coatingsurface is coarse.Because of spring piece and cathode screen point of contact are few, distribution of current is inhomogeneous, influences the use properties of electrolyzer; So electrolytic bath voltage is high, energy consumption is high, damages ionic membrane easily.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of performance the higher and tangible film pole span of energy-saving effect ion-exchange membrane electrolyzer.
The purpose of the utility model is achieved in that a kind of film pole span ion-exchange membrane electrolyzer; Comprise cathode disc and cathode screen, be provided with the nickel lath between said cathode disc and the cathode screen, be provided with elastic network(s), nerve of a covering and cathodic activity net on the said cathode screen successively; The bottom surface of said elastic network(s) and cathode screen welding; The edge of said nerve of a covering and cathode screen welding, said cathodic activity net adopt thin nickel strap to be welded on the edge of cathode disc trim, and said elastic network(s) is the nickel wire mesh grid; Said activated cathode net is the nickel wire mesh grid, and the surface of said activated cathode net is provided with the heated oxide noble coatings.
Compared with prior art, the beneficial effect of the utility model is:
The utility model has been realized the film pole span owing to fit through elastic network(s) is flexible between cathode screen and ionic membrane, reaches energy-saving effect; Cathode screen has become the nickel wire mesh grid by original pulling eye net, and the electrolysis specific surface area increases, and makes distribution of current even, and bath voltage descends, and electrolytic efficiency improves, and energy-saving effect is remarkable.
