Description

System fluorine carbon anode mechanism

Technical field

The utility model belongs to system fluorine field, relates to a kind of system fluorine carbon anode mechanism.

Background technology

Electrolysis system fluorine is to lose electric charge through fluorion in the electrolytic solution at anode surface to be oxidized to fluorine gas; The desorption process that fluorion fluorine gas on anodic diffusion and the anode surface steeps in the solution all will lean on big as far as possible anode specific surface area; But because the space is limit in processing requirement and the groove, in electrolysis system fluorine technology, a kind of contradictory phenomena just occurred, increased electric current and help the increase of fluorine gas output; Make carbon anode produce polarization easily but electric current increases, can cause fluorine gas output to reduce again.

Summary of the invention

The utility model problem to be solved provides a kind of system fluorine carbon anode mechanism, and solving has big as far as possible carbon anode surface-area in the restriction fluorine groove, improves output, reduces cost, and reduces polar and takes place.

For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:

A kind of system fluorine carbon anode mechanism comprises the carbon anode plate, and said carbon anode plate surface is provided with axial recess.

Said groove is a dovetail groove.

Said trapezoidal groove depth 8mm, last hem width 10mm, following bottom width 6mm.

The utility model carbon anode plate is provided with groove, and solving has big as far as possible carbon anode surface-area in the restriction fluorine groove, helps under original equipment situation, improving output, reduces cost, and reduces polar and takes place, and helps prolonging the carbon anode life-span.

Embodiment

As shown in Figure 1, be the synoptic diagram of the utility model structure, a kind of system fluorine carbon anode mechanism comprises carbon anode plate 1, and carbon anode plate 1 surface is provided with axial recess 2, and groove is a dovetail groove, and carbon anode plate 1 inside is axially arranged with two upper screwed holes 3, is used to connect lead; Fig. 2 is the utility model structure vertical view, and trapezoidal groove depth H is 8mm, and top L is 10mm, and the W that goes to the bottom is 6mm; Fig. 3 the utility model structure A-A sectional view, threaded hole 3 is positioned at carbon anode plate 1 inside.

The carbon anode plate variable size that this use is novel is an example with 600 * 180 * 50mm carbon electrode plate, calculates by immersing ionogen 500mm; Surface-area is 0.23 ㎡, adopts the utility model surface-area can increase to 0.386 ㎡, and carbon anode and ionogen contact area have added 67.8%; Increase effectively carbon anode and ionogen contact area, improved fluorine gas output, under the situation of big electric current input, still keep the low current density in carbon anode surface; Reduced the generation of polarization phenomena; Stopped the depolarize operation, thereby prolonged the carbon anode life-span, obtained reducing production costs and improved the purpose of production capacity.

Through example, the concrete application of the utility model is described below:

Example 1, certain 4KA of company electrolyzer, former bath voltage 9.5V, electric current 4000A start and after 3 days polarization phenomena just take place, and in process of depolarization, cause a large amount of carbon anodes phenomenon that fractures; After using the utility model instead, promptly use the dull and stereotyped carbon plate of 600 * 180 * 5mm, on the carbon anode plate, be provided with groove; Groove is a dovetail groove, trapezoidal groove depth 8mm, last hem width 10mm; Following bottom width 6mm, bath voltage is reduced to 9.1V, and current boost is to 4500A; But carbon anode is lower than originally with the electrolyte interface watt current, and 0.05A/cm2 has used 4 months and polarization phenomena still do not occurred; The fluorine gas rate ratio is not used the every groove of this product fecund every day fluorine gas 7.6kg, and carbon anode plate life cycle is for 300 days, and ton fluorine gas production cost has descended 800 yuan.

Example 2, the red Ward kind of the preceding center gas 3000A of Leshan branch office of limited-liability company electrolyzer, when the dull and stereotyped carbon plate that uses 600 * 180 * 50, mean current 2900A; Average cell voltage 9.7V, mean lifetime 73 days uses the utility model on 2 electrolyzers, to test; Still operational excellence after 125 days; Mean current 2950A, average cell voltage 9.2V on average economizes on electricity more than 5%.

The carbon slab that example 3, the red Ward kind of the preceding center gas 10KA of Wenjiang company of limited-liability company electrolyzer use is 600 * 300 * 70mm, opposes than test with 4, and wherein 2 with in the past dull and stereotyped carbon slab; Use the utility model for other 2, at the test initial stage, polarization phenomena all appear in dull and stereotyped carbon slab; And polarization phenomena all do not appear in the carbon slab of fluting, and test current all is controlled at 9000A, after 2 months; Wherein polarization phenomena appear in 1 dull and stereotyped carbon slab once more, and depolarize is handled the back and recovered normal, the contrast potential situation; 2 dull and stereotyped carbon slab electrolyzer average voltages are 9.5V, and 2 fluting carbon slab average voltages are 9.1V, find out that the fluting carbon slab can economize on electricity more than 4.2%.
