The present invention relates to a nitrogen ion generating device and method of the ionizer, in particular to replace the electrode of the ionizer with a good life single crystal silicon electrode to extend the life of the ionizer and to supply air or nitrogen to the input of the tube fitting air Ion black is to generate nitrogen ions.

Conventional ionizers use metal titanium needles to generate ions, which cause friction and shape change in a short period of time, and sputtering and chemical corrosion are severe, causing frequent replacement and contamination of the electrode. have.

However, the above reason is that dust accumulated on the electrode promotes oxidation reaction of the electrode while generating ions, which causes surface contamination due to electrostatic adsorption of particles and deteriorates performance.

In addition, the conventional ionizer has a problem that it is impossible to generate nitrogen (N ₂ ) ions that occupy most of the air by ionizing only oxygen (O ₂ ) ions in the air.

In view of the above, the present invention replaces the electrode with a single crystal silicon electrode which is not contaminated with metal and has a very good life of the electrode, and further improves the direct current method by sequential. It aims to efficiently generate air ions or nitrogen ions by controlling ion generation of the ionizer by the bipolar method.

The present invention will be described in detail below with reference to the accompanying drawings.

First, referring to the configuration of the ionizer, as shown in FIG. 1, the modular jack 1 which receives AC power from the power supply means, and converts the AC power from the modular jack 1 into DC power, A high-voltage DC power supply unit (2) generating a high voltage from the (+) electrode and the (-) electrode, which has a heavy level, and the air ions and the ionization reaction of the (+) and (-) electrodes (7). A supply means for supplying clean air or nitrogen to generate nitrogen ions, and a siege air nozzle 3 for dissipating ions generated from the (+) and (-) electrodes 7 into the air.

And the supply means is a flow control valve (5) for controlling the amount of clear air or nitrogen supplied to the input of the tube fitting (4), and the air or nitrogen gas moved through the flow control valve (5) with high purity After filtration, a membrane filter 6 was constructed to move to the siege air nozzle 3.

In addition, the electrode 7 is composed of single crystal silicon (Si) which does not become a metal contamination and has an excellent life of the electrode.

The ionizer of the present invention configured as described above further improves the direct current (DC) method and performs ion generation control by the sequential and bipolar methods to efficiently and accurately perform ion generation control, and It is possible to create an environment free of static electricity by increasing the conductivity of air from +) and (-) ions and neutralizing and attenuating electric charges of insulators and conductors.

(+) And (-) ions are generated by corona discharge when DC high voltage is applied to the electrode 7, and the air molecules around the electrode 7 can be converted into (+) and (-).

The recombination rate of the air ions generated from the electrode 7 can be reduced by adjusting the generation time of the DC high voltage by the DC high voltage power supply unit 2 in the sequential and bipolar manner and simultaneously setting the OFF TIMING. It can improve the efficiency in the environment according to the distance and wind speed, and can supply air ions extensively.

In addition, in order to allow the ion level to be optimally adjusted by adjusting the output voltage, the outputs V ₁ , V ₂ timings t ₁ , t ₂ , t ₃ , t ₄ can be independently adjusted as shown in the block diagram of FIG. 2.

Nitrogen gas is a low level of the electronic energy level of the vibration is a 6.2V 0.29V, and the rotation level is lowest is 2.4 × 10 ^-4 V.

Therefore, excitation does not occur when nitrogen atoms collide with each other, and only elastic layer stones occur. When collision of nitrogen molecules causes vibration excitation and rotation excitation, the internal energy of the nitrogen gas can be increased, and inelastic collision between molecules can occur. .

As a result, in the case of molecular gas rather than atomic gas, inelastic collision (electron energy loss) is more likely to occur, whereby nitrogen is generated by inelastic collision between molecules, resulting in nitrogen ions. Through the flow control valve (5) and through the membrane filter (6), it is generated in the holder of the electrode (7) and the generated nitrogen ions surround the electrode (7) to prevent corrosion and sputtering of the tip It can prevent.

In addition, the DC power supply unit 2 of the present invention should have a rotational frequency of 875 (Gauss) of the magnetic field of the electron in order to cause inelastic collisions of nitrogen molecules, and the microwave has a frequency of 2.45 (㎓) as the power source. . At this time, resonance occurs due to the coincidence of frequencies.

By using the resonance phenomenon, positive ion generation and negative ion generation efficiency are higher and higher density ion formation than general ion acceleration and collision ion generation methods.

In addition, the discharge phenomenon can be maintained even at a low pressure. As shown in FIG. 1, the electrode is far from the DC high-voltage power supply unit and does not exist in the discharge region, so that the electrode is not contaminated.

As described above, the present invention extends the lifetime of the ionizer by replacing the electrode of the ionizer with a single-crystal silicon electrode having a good lifespan, and supplies air or nitrogen to the input of the tube fitting to supply air or nitrogen in the sequential or bipolar manner. Or it is an invention that can generate nitrogen ions.
