Description

A kind of Ti electrode of new structure

Technical field

The utility model is related to electrode technology field, the titanium of specifically a kind of new structure for increasing electrode contact area Electrode.

Background technology

At present purified water most efficient method is electrochemical process, and its advantage is that floor space is little, not by seasonal effect, is processed Cycle is short, is to develop a kind of new technology faster in recent decades.The most important factor of electrochemical treatments efficiency is affected to be electrode Material, the selection of electrode material is in core status in electrochemical treatments technology.Different electrode materials is useless to all types of industries Water process has a significant impact, and particularly has a significant impact to treatment effect and operating cost (i.e. power consumption).

General electrode material will have good electric conductivity, and pole span change is little, and corrosion resistance is strong, mechanical strength and processability Can be good, life-span length, expense is low, has good electrocatalysis characteristic to electrode reaction, and current titanium is most to meet the above comprehensively The metal asked.

Ni―Ti anode dimensionally stable, shape makes easy, can high precision int.Titanium base is reusable.Electricity in electrolytic process Anode-cathode distance does not change, it is ensured that electrolysis procedure is carried out in the case where tank voltage is stable.Operating voltage is low, and power consumption is little, Ni―Ti anode long working life, corrosion resistance is strong.The problems of dissolution of graphite anode and lead anode can be overcome, it is to avoid to electrolyte and the moon The pollution of pole product.Current density is high, and overpotential is little, and electrode catalyst activity is high, can effectively catch high efficiency.Low overpotential Characteristic, the bubble of surface and electrode is easily excluded between electrode, can effectively reduce bath voltage.Reduces cost.

Utility model content

Main purpose of the present utility model is, there is provided a kind of Ti electrode of new structure, technical problem to be solved It is the contact area that can increase two electrodes in one group of electrode in certain volume, so that electrode volume is effective Reduction.

The technical solution adopted in the utility model is：

A kind of Ti electrode of new structure, the electrode is by the U-shaped electrode plate groups of two panels into being in after the combination of multipair electrode arrangement The electrode group of " bow " character form structure；The U-shaped battery lead plate of two panels be positive electrode, negative electrode；The U-shaped battery lead plate inner surface is uniformly provided with Several cylindrical protrusions or pit.

The beneficial effects of the utility model are：

The utility model structure includes the single electrode of two U-shape structures, and surface is in raised or sunken undulated, the two lists Electrode is combined into bending font or sleeve-like configuration so that the effective contact area between two single electrodes increases.Electrode Surface scribbles ruthenium system metal or oxide, accelerates electrode to produce hypochlorite, plays bactericidal action.The utility model tank voltage Stability is high；Operating voltage is little, and the consumption of electric energy is low, and current density is big, and corrosion resistance is strong；Long service life；Electrode weight is light.

Specific embodiment

The utility model is further described with reference to Figure of description and reference.

As shown in figures 1-8, a kind of Ti electrode of new structure, the electrode is by the U-shaped electrode plate groups of two panels into multipair electrode row Electrode group in " bow " character form structure after row combination；The U-shaped battery lead plate of two panels be positive electrode 1, negative electrode 2；The electrode group can increase Large access area, reduces electrode volume.

The U-shaped battery lead plate inner surface is uniformly provided with several cylindrical protrusions or pit.

The U-shaped battery lead plate inner surface is uniformly provided with several rectangle projections or pit.

The U-shaped battery lead plate inner surface is uniformly provided with several rhombus projections or pit.

The U-shaped battery lead plate inner surface is uniformly provided with several spherical protuberances or pit.

The U-shaped battery lead plate is made up of titanium；The U-shaped electrode plate surface coating be metal Ru, iridium, platinum, rhodium and its Oxide.

The U-shaped battery lead plate adopts netted open-end hole structure.

The U-shaped battery lead plate adopts ellipticity through-hole structure.

The U-shaped battery lead plate is the cylinder that two correspondences are nested together, and the drum surface is provided with several through holes.

Embodiment

Used as anode, face coat is metal Ru and its oxide, independent titanium to titanium-based noble metal oxide coating in electrode Plate is used as negative electrode.Because there is ruthenium inertia to be difficult to be oxidized, so making the electrode of jointed anode becomes an inert electrode, logical Electric rear electrode sends electronics, makes the chlorine in water be oxidized to form hypochlorite, and then hypochlorite can carry out sterilization to water, Specific chemical equation is Cl₂+H₂O==HCl+HClO.
