Abstract
The invention relates to a platinum tantalum titanium composite anode, The platinum tantalum titanium composite anod comprises a titanium substrate (1), wherein feeding/discharging holes (4) are formed in the titanium substrate (1) diagonally; a tantalum foil (2) is fixed on the inner side of the titanium substrate (1) and covers the inner side of the titanium substrate (1); feeding/discharging holes (5) are formed in the corresponding positions of the tantalum foil (2); platinum flat wires (3) are fixed on the surface of the tantalum foil (2) and are arranged uniformly in the longitudinal direction. During electrolysis of the platinum tantalum titanium composite anode, the platinum and the tantalum are in direct contact with materials and can resist corrosion of acid, alkali and ammonium sulfate, so the dropping phenomenon caused by corrosion is avoided; the titanium substrate is not in contact with the materials, so corrosion is avoided; the service life and the repair cycle of the anode can be prolonged exponentially; the platinum almost has no loss during the use, so the maintenance cost is greatly reduced.
Description
Technical field
The invention belongs to Process for Electrosynthesis of Ammonium Persulfate equipment technical field, be specifically related to a kind of platinum tantalum titanium composite anode.
Background technology
Process for Electrosynthesis of Ammonium Persulfate, the anode material of electrolyzer generally adopts platinum-titanium composite anode, platinum-tantalum-Yin composite anode, platinum-titanium-copper composite anode etc., and the form of anode has the forms such as board-like, box and tubular type.Platinum-titanium composite anode, platinum-titanium-copper composite anode are in use, owing to having the materials such as ammonia, sulfuric acid, ammonium sulfate and ammonium persulphate in anode electrolytic cell feed liquid, cause titanium base material to corrode, platinum filament is come off, cause the defects such as the maintenance frequency of electrolyzer increases, the easy loss of platinum.Platinum-tantalum-silver electrode composite, is be attached on silver-colored rod by tantalum pipe, then is wrapped on tantalum pipe by platinum flat filament, by the mode of spot welding, is fixed on by platinum flat filament on tantalum pipe and forms combined electrode.Because electrode does not have cooling infrastructure, in the process that energising runs, electrode generates heat, and affect electrolytic efficiency, power consumption is higher, cost increase.
Summary of the invention
The technical problem that the present invention solves: design a kind of platinum tantalum titanium composite anode, titanium base material does not contact with material, there is not titanium base material and corrode the anode damage problem caused, work-ing life and the turnaround of anode can be extended at double, and platinum loss hardly in the process used, the maintenance cost of electrolyzer is greatly reduced.
Technical solution of the present invention: a kind of platinum tantalum titanium composite anode, comprise titanium-base, and on titanium-base, diagonal angle is shaped with entry/exit material hole I; The medial surface of described titanium-base is fixed with tantalum paper tinsel the medial surface of titanium-base is covered, and the correspondence position on tantalum paper tinsel is shaped with entry/exit material hole II; The surface of described tantalum paper tinsel is fixed with platinum flat filament, and platinum flat filament is longitudinally evenly distributed.
Described tantalum paper tinsel welds with the medial surface of titanium-base at entry/exit material hole II place, makes to seal between entry/exit material hole II and titanium-base medial surface; The thickness of described titanium-base is 1.5-2mm, and the thickness of tantalum paper tinsel is 0.15-0.2mm.
Explosion composite between described tantalum paper tinsel and the medial surface of titanium-base; The thickness of described titanium-base is 2-2.5mm, and the thickness of tantalum paper tinsel is 0.5-0.8mm.
The advantage that the present invention has and effect: during electrolysis of the present invention, platinum directly contacts with material with tantalum, due to the corrosion of platinum and tantalum acid-and base-resisting and ammonium sulfate, can not form the phenomenons such as corrosion comes off; The contact of titanium-base discord material, can not produce corrosion; Therefore, work-ing life and the turnaround of anode can be extended at double, and platinum loss hardly in the process used, maintenance cost is greatly reduced.And then extend turnaround and the life-span of electrolyzer, improve electrolytic efficiency, reduce power consumption, save productive expense.
