Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, hospitals, kitchens,
Positive ions and negative ions in ionized gas for the purpose of air purification system mainly for supplying negative ions that make air environment comfortable in halls etc., that is, it is considered to be good for health and also effective for sterilization, dust removal and deodorization The present invention relates to an ion mixing ratio adjusting device.

In addition, the present invention prevents the electrification of materials and products in the electronic equipment, printing, milling, textile-related industries and the like, that is, removes all kinds of electrostatic charges such as positively or negatively biased electrostatic charges and continuously generated electrostatic charges. The present invention also relates to an apparatus for adjusting the mixing ratio of positive ions and negative ions in an ionized gas. Further, the present invention relates to a device for adjusting a mixture ratio of positive ions and negative ions in ionized gas, which is also intended to remotely apply electrostatic charge required by an object.

2. Description of the Related Art Conventional devices for adjusting the mixing ratio of positive ions and negative ions in ionized gas include a device for separately adjusting the voltage applied to the positive electrode and the negative electrode in corona discharge, and a device for adjusting the water flow to a solid solid. There is a device for applying ionized gas generated by hitting the sample to a centrifuge, and a device using 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 directly irradiating X-rays or spraying ionized gas simply by X-rays, the same amount of positive ions and negative ions reaches the periphery of the object, so that the object is continuously charged. In this case, ions of the same polarity as the charge of the object 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 for Solving the Problems and Action] A distribution region of an ionized gas in which a gas mixed with positive ions and negative ions generated by X-ray irradiation or the like or a gas mixed with positive ions and negative ions similarly generated An electrode of an appropriate shape is placed in the basin of the ionized gas that is moving, and the polarity and height of the voltage applied to the electrode are adjusted to adjust the mixing ratio of positive ions and negative ions in the ionized gas. is there.

The operation of the 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 or a basin of 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. This phenomenon propagates in a chain and creates a state with a large amount of negative ions in the ionized gas distribution area or the entire basin. Similarly, when a positive voltage is applied to the electrode, a state in which the amount of positive ions is large in the entire distribution region or basin of the ionized gas is created. 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.

That is, the polarity and the level of the voltage applied to the ion adjusting electrode (6) arranged in the basin of the ionized gas (5) in which the positive ions and the negative ions generated by the ionized gas generator (4) are mixed are adjusted. This figure shows the electrode for ion adjustment (6)

FIG. 2 shows an X-ray emitter (7) and a blower (8).
A positive voltage was applied to dust (9), which was negatively charged due to the attachment of negative ions generated by the ion adjusting electrode (6) to which a negative voltage was applied and which was disposed in the basin of the ionized gas sent by the method (1).

FIG. 3 shows an X-ray emitter (7) and a blower (8).

This is an embodiment of the static eliminator in which a gas having a mixture ratio of a positive ion and a negative ion required for each duct is blown out by adjusting a voltage applied to the adjustment electrode (6).

When the target is temporarily electrostatically charged, the electrostatic charge can be removed by the same amount of positive ions and negative ions. For example, continuous charges such as powder ejected from a nozzle or a rotating belt can be used. When electrostatic charging occurs, ions of the same polarity as the object are continuously consumed with the same amount of positive ions and negative ions, so that ions of the same polarity as the object remain and are filled. According to the present invention, the mixing ratio of the positive ions and the negative ions can be adjusted according to the charging state of the target object.
Even when static electricity is continuously generated in the target object, effective static electricity can be removed.

It is necessary to use a dust collector to which a positive voltage is applied to efficiently remove dust to which negative ions have adhered while supplying negative ion-enhanced air which is considered to be healthy if this device is used. An air purification device that can be realized is created.

Further, there can be provided a device capable of coping with an object having a different electrostatic charge for each part according to the part.
