2. Description of the Related Art As conventional apparatus for ionizing gas generator, a device utilizing corona discharge, and Leonard effect hit the water flow to a rigid solid, there is equipment that utilizes an ion exchange resin.

As a device for removing static electricity by an ionized gas, there is a device using the above-described corona discharge or a device that directly irradiates X-rays or sprays ionized gas by X-rays.

[0005] As an air purifying apparatus using ionized gas, an apparatus utilizing corona discharge is mostly used, and there are an apparatus utilizing the Leonard effect and an apparatus utilizing an ion exchange resin.

[0006]

However, in an apparatus utilizing corona discharge, noise generated by a high-voltage electrode for corona discharge and ozone and nitrogen oxides generated by the discharge adversely affect objects and personnel. There is a danger or risk of explosion due to electric shock or corona discharge.

A device utilizing the Leonard effect has a complicated structure such as a mechanism for colliding a high-speed water stream with a hard solid to generate ionized gas and a centrifugal separator for ion separation, and is liable to cause mechanical failure.

[0008] An apparatus using an ion exchange resin cannot be expected to have any ion quantity that can affect the environmental improvement.

It is not easy to adjust the mixing ratio of positive ions and negative ions to an arbitrary ratio in any apparatus using corona discharge, Leonard effect, or ion exchange resin.

In an apparatus for removing static electricity by simply irradiating X-rays, the same amount of positive ions and negative ions reaches the periphery of the object. Ions of the same polarity are filled and the electrostatic charge cannot be removed.

Therefore, the present invention is to improve the above-mentioned drawbacks of the conventional apparatus, and to supply negative ions by freely adjusting the mixing ratio of positive ions and negative ions in the ionized gas by a simple mechanism. The present invention enables drastic measures against static electricity, such as air purification at the center and a case where the object is continuously charged.

[Means and Actions for Solving the Problems] An electrode of an appropriate shape is arranged in an ionized gas distribution region in which a gas containing a mixture of positive ions and negative ions generated by X-ray irradiation or the like is applied and applied to the electrode. This is a device for adjusting the mixture ratio of positive ions and negative ions in ionized gas by adjusting the polarity and height of the applied voltage.

The operation of this apparatus will be described with reference to the case where an electrode to which a negative voltage is applied is arranged in a distribution region of an ionized gas in which positive ions and negative ions are mixed. Since the electrode to which the negative voltage is applied adsorbs the nearby positive ions, the vicinity of the electrode is an area with a large amount of negative ions. The area with an excess of negative ions absorbs nearby positive ions, and the neighborhood becomes an area with an excess of negative ions. Create a lot of negative ions state this phenomenon in distribution areas entire chain to propagate ionized gas. Similarly, if a positive voltage is applied to the electrode creating a greater state of positive ions to the distribution area entire of ionized gas.
By appropriately setting the voltage applied to the electrode, the same amount of positive ions and negative ions can be obtained, or a state of only positive ions or negative ions can be realized.
