An anion-releasing electrode with superconducting properties

Abstract

The invention provides a rare-earth-doped needle-like silver-copper-tin alloy superconductive anion release electrode high in concentration of generated anions and effective in reduction of generated derivatives. The superconductive anion release electrode comprises an electrode body made of copper-tin alloy, and the electrode body is externally coated by a conductive layer made of silver and rare earth. Since impedance of the conductive layer which externally covers the electrode body is smaller than that of the electrode body, electric ion release amount can be further increased; in addition, due to the fact that the electrode body is made of copper-tin alloy, heat resistance and corrosion resistance can be improved, and the service life of the electrode body is prolonged; the conductive layer is made of a rare-earth-doped silver material, and silver is best in conductivity of all current metals, electrical resistivity of silver is only 1.586*10-8 omega m at the normal temperature, and the silver not only has superconductivity bus also is capable of killing bacteria in air.

Description

technical field [0001] The invention relates to components of an air ion generator, in particular to an ion releasing electrode with superconducting properties. Background technique [0002] The ionizer is a device that generates air ions. After the input DC or AC is processed by the EMI processing circuit and the lightning protection circuit, it passes through the pulse circuit, overvoltage and current limiting; high and low voltage isolation and other lines are upgraded to AC high voltage, then rectified and filtered by special-grade electronic materials to obtain pure DC negative high voltage, connect the DC negative high voltage to the release electrode made of metal or carbon elements, use the cutting-edge DC high voltage to generate high corona, and release a large number of electrons at high speed ( e-), and the electrons cannot exist in the air for a long time (the lifetime of the electrons that exist is only nS level), and they will be captured by the oxygen molecul...

Problems solved by technology

[0003] Ion release electrodes made of steel needles, tungsten steel needles, ordinary carbon fibers and other materials have relatively high resistance, so a relatively high release voltage is required to make the ionizer generate a large dose of air ions, which is costly and has a high risk factor. At the same time, while producing a higher dose of ions, there are also many derivative products such as ozone, nitrogen oxides, electromagnetic waves and static electricity pollution.

[0004] It has been recently reported that the market also uses fullerene materials as ion-releasing electrodes. Because fullerene has superconducting characteristics, the resistance is almost equal to zero, which can effectively overcome the above shortcomings. However, fullerene is expensive and costly. It is conducive to the application and promotion of ordinary products, and the release electrode of the ion generator is made of fullerene, which is aggregated into bundles of thousands of hair-like filament tips. Because air ions have excellent dust-reducing effect, the ion The release tip of the generator is easy to attach ultra-fine dust, and the fullerene release electrode composed of several filaments is not only difficult to take care of after dust is attached to it, but also increases the resistance of the fullerene release electrode and reduces the conductivity, so After a period of use, there will be ozone and nitrogen oxides
