Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air cleaning apparatus using atmospheric pressure dielectric barrier discharge

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air cleaning apparatus using atmospheric dielectric diaphragm discharges, and more particularly, to an air purifying apparatus using atmospheric dielectric diaphragm discharges using a tubular dielectric.

Industrial facilities are continuously increasing according to the development of industries, the pollution degree of air generated in the increasing industrial facilities is increasing, and various forms for purifying the air of the living space according to the characteristic of modern people pursuing the quality of life An air purifying device of the present invention has been developed.

In the living environment, air has various factors such as temperature, humidity, and contained substances. Depending on the value, the air comfort or health influence is influenced. Containing substances include various substances such as industrial pollutants such as dust and exhaust gas, pollen, microorganisms, and odors in addition to ordinary Jinhae.

In a region rich in natural environment, it is possible to obtain pleasant air only by natural ventilation. However, in a bad environment, it is necessary to artificially reform air to obtain pleasant air, and the apparatus for air reforming is an air purifier.

In the case of an air purifier, various types of air can be purified in a desired space. In particular, the demand for air purifiers using plasma is increasing.

In the case of purifying the air using the plasma, the efficiency of the air purification and the filter are exchanged in comparison with the method of purifying the air by using the filter or the like, which is a favorite method because it is not troublesome to exchange the filter.

In addition, the plasma generated at a high pressure near atmospheric pressure can be largely divided into a low-temperature plasma and a high-temperature plasma. A high-temperature plasma is a typical type of arc discharge having low voltage and large current characteristics.

The low-temperature plasma can be classified into corona discharge, dielectric barrier discharge, and glow discharge depending on the discharge characteristics. In case of the corona discharge, a slight luminescence phenomenon can be observed around the end portion when a high voltage is applied to the metal electrode having a sharp tip. As shown in FIG.

That is, the electric field at the end causes the discharge breakdown electric field to start the discharge. The corona discharge can charge particles floating in the air due to small active volume around the point, and can accumulate particles at high voltage at the electrode, so that dust collector, copier, exhaust gas treatment, dry ore separation, radiation detection etc. It is applied to many fields.

The dielectric barrier discharge is also referred to as silent discharge, and a dielectric layer is provided on one or both of the two electrodes. The dielectric plays an important role in giving proper function of the discharge, and when ionization takes place at one position between the discharge electrodes, the carried charges are accumulated in the dielectric.

At this time, the dielectric material functions to limit the amount of electric charge transferred by one micro-discharge and to spread the micro-discharge over the entire electrode. In addition, micro-discharge by a streamer having a high current density locally on the discharge space Lt; / RTI >

On the other hand, Korean Patent No. 10-0566851 discloses an invention relating to an air conditioning apparatus and an ion generating apparatus used therein, and the above patent discloses an air conditioning apparatus equipped with an ion generating apparatus, Disclosure of the Invention The present invention relates to a device for changing the factors that determine the properties of air to a comfortable or healthful state in the human body.

The patent discloses an air conditioner comprising a blower for circulating air in the room, a circulation passage for passage of wind blown by the blower, and a blowing passage separate from the circulation passage, The air conditioning apparatus comprising an ion generating device for generating air.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air purifier using an atmospheric pressure dielectric barrier discharge in which safety and purification ability are improved.

Another object of the present invention is to provide an air purifier using an atmospheric pressure dielectric barrier discharge which is easy to assemble and has improved air purification efficiency.

An air purifier using an atmospheric pressure dielectric barrier rib discharge according to the present invention comprises: a tube-shaped dielectric member having an inner space and being shielded at one end thereof; An outer conductor located outside the dielectric; An inner conductor located in an inner space of the dielectric; An electrode connected to the internal conductor to apply a voltage; A power applying unit connected to the electrode to apply power to the electrode; And a dielectric support for supporting the dielectric; .

The air purifying apparatus using the atmospheric pressure dielectric barrier rib discharge according to the present invention comprises a dielectric body having a tube shape shielded at one end thereof and an inner conductor and an outer conductor located on the side of the outer space of the dielectric body.

When an AC high voltage is applied to an inner conductor located in a tube-shaped dielectric inner space, a discharge is generated between an outer conductor located in an outer space of the dielectric and the dielectric, .

As the air purification using the atmospheric dielectric diaphragm discharge proceeds, the metal electrode can be prevented from being exposed to the space where the discharge is formed, and the metal electrode can be hidden, It is possible to expect an effect of improving the safety.

In addition, since direct exposure of the metal electrode is prevented, it is possible to reduce the amount of ozone generation compared to the corona discharge. The reduction in the amount of ozone generated has the advantage of preventing ozone damage of the user's body.

In addition, the space to which the high voltage is applied becomes the inner space of the dielectric, and the outer space and the high-voltage applied space of the dielectric are spatially separated by the dielectric, so that the safety can be further improved.

The use of such a tubular dielectric material enables the use of an air purifier using an atmospheric dielectric diaphragm discharge, so that a compact air purifier can be manufactured, and various effects can be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an air purification apparatus using an atmospheric pressure dielectric partition according to the present invention will be described with reference to the accompanying drawings.

It is to be understood, however, that the scope of the present invention is not limited by the embodiments described below, and those skilled in the art, upon reading the present disclosure, It will be easily suggested, but this will also be included in the technical idea of the present invention.

It is to be understood that the terms used in the present specification or claims are selected for convenience of description and should be interpreted appropriately in accordance with the technical idea of the present invention when grasping the technical contents of the present invention.

FIG. 1 is a perspective view of an air purification apparatus using an atmospheric pressure dielectric diaphragm discharge according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of an air purification apparatus using an atmospheric pressure dielectric diaphragm discharge according to an embodiment of the present invention .

FIG. 3 is a schematic front cross-sectional view illustrating an internal configuration of an air purifying apparatus using an atmospheric pressure dielectric partition according to an embodiment of the present invention. FIG. 4 is a cross-sectional view illustrating an internal configuration of an air purifying apparatus using an atmospheric pressure dielectric partition according to an embodiment of the present invention Fig.

Referring to FIG. 1, an air purifier according to an embodiment of the present invention includes a dielectric 10 in the form of a tube having an inner space and being shielded at one end thereof, An inner conductor 30 positioned in the inner space of the dielectric 10 and an electrode 40 connected to the inner conductor 30 to apply a voltage to the inner conductor 30, A power applying unit 50 connected to the electrode unit 40 to apply external power to the electrode unit 40 and a dielectric support unit 60 for supporting the dielectric unit 10.

The dielectric 10 is made of a quartz material and is formed in the shape of a cylinder having a certain degree of internal space. The surface of one end in the longitudinal direction is formed to protrude in the form of a hemisphere outward in the longitudinal direction, And the other end is formed to have an open face.

Of course, it is also possible that the dielectric 10 is formed in the shape of a cylinder having an inner space of a certain size, and is formed so that one surface in the longitudinal direction is shielded and the other end is opened.

In the embodiment of the present invention, a configuration in which a protrusion is formed in the form of a hemisphere is disclosed, which may be a configuration for improving safety for preventing a user's body from being damaged.

The reason why the dielectric body 10 is made of quartz material is that it is possible to apply a high current due to the characteristic of quartz because of its high heat resistance and characteristic of quartz so that even if a high voltage current is applied to the internal conductor 30, Can be prevented from being broken.

The dielectric 10 is formed to be transparent so that the user can check the internal space. This is to ensure atmospheric pressure dielectric barrier discharge phenomena and lifetime between the dielectric 10 and the inner conductor 30 in a state where a high voltage current is applied to the inner conductor 30 located in the inner space of the dielectric 10 to be.

That is, since the dielectric 10 is made of a quartz material, when the life of the dielectric 10 is short, the dielectric 10 is opaque but not transparent, so that the user can visually confirm the life of the dielectric 10.

However, when the dielectric material 10 is made of a glass material, it may be weak to heat, and may cause injury to the user or damage to the product due to breakage, so that it is not preferable to use the glass material.

The external conductor 20 is made of a metal material, such as tungsten or the like, through which current flows, and is formed into a mesh shape in the form of a rectangular plate. Of course, it is also possible that the external conductor 20 is processed in an embossed form on a surface of a rectangular plate shape, not in the form of a metal mesh.

At this time, it is preferable that the external conductor 20 is in the form of an embossing protruding in the direction of the dielectric body 10. Of course, it is also possible to adopt an embossing shape which protrudes both in the direction in which the dielectric body 10 is located and in the outer side direction of the dielectric body 10, but the shape of the embossing protruding only in the outer direction of the dielectric body 10 is preferable I will not.

The external conductor 20 performs a function of generating a discharge with the dielectric 10 when a high voltage current is applied to the internal conductor 30. In other words, if a high voltage current is applied to the inner conductor 30, atmospheric pressure dielectric barrier discharge may occur between the dielectric 10 and the outer conductor 20.

By the discharge phenomenon occurring between the dielectric 10 and the external conductor 20, the inclusion material contained in the air in the space where the dielectric 10 is located is oxidized, and the air in the space where the air purification device is located is oxidized It cleanses cleanly.

The inner conductor 30 is located along the inner side surface of the dielectric 10. The inner conductor 30 is formed in the shape of a rectangular plate having a certain thickness and is disposed in contact with the inner side surface of the dielectric body 10.

The inner conductor 30 has a plurality of holes and is formed in the form of a net. The longitudinal end portion of the inner conductor 30 in the direction in which the dielectric body 10 is shielded is more protruded than the longitudinal end portion of the outer conductor 20 . This is to improve user safety and discharge efficiency.

That is, when the longitudinal end portion of the inner conductor 30 is formed to protrude further in the longitudinal direction of the dielectric 10 than the longitudinal end portion of the outer conductor 20, 20 and the dielectric body 10 is reduced, thereby reducing the discharge efficiency.

Therefore, it is preferable that the length of the inner conductor 30 is equal to the length of the outer conductor 20.

Also, the internal conductor 30 may be formed in an embossed shape instead of a perforated network. At this time, it is preferable that the internal conductor 30 is formed in an embossing shape protruding in the direction of the dielectric body 10.

Of course, it is also possible that the internal conductor 30 is formed in an embossed form protruding in the direction of the dielectric 10 and the internal space of the dielectric 10, Since the shape of the embossing is independent of the discharge, it is preferable that the internal conductor 30 is formed in the form of an embossing protruding in the direction of the dielectric body 10.

A dielectric support 60 for supporting the dielectric 10 and the internal conductor 30 is disposed on an open surface of the dielectric 10. The dielectric support portion 60 is formed of a material of an insulator which is not energized with current, and is formed in a disk shape having an inner space with a certain thickness.

That is, the dielectric supporting portion 60 is formed in the shape of a disk made of an insulating material, and the central portion is formed to be recessed to have an internal space, And the end portion is received.

The dielectric support 60 is configured to support the dielectric 10 while a portion of the dielectric 10 in the open direction is received in the interior space of the dielectric support 60.

At this time, an open portion of the dielectric body 10 is configured to be fixed to the inner space of the dielectric support portion 60 by interference fit such as interference fit. Of course, it is also possible that the dielectric 10 is supported on the dielectric support 60 while the dielectric support 60 and the dielectric 10 are coupled by a fastening member.

A central portion of the dielectric supporting portion 60 is provided with an electrode portion 40 for supplying a high voltage current to the internal conductor 30 and a power applying portion 50 for applying an external high voltage current to the electrode portion 40. [ .

The power applying unit 50 is connected to the electrode unit 40 through the dielectric supporting unit 60 and is connected to an external high voltage current and supplies a high voltage current to the electrode unit 40 .

The electrode unit 40 is connected to the internal conductor 30 by a cable or an electric wire and transmits a high voltage current applied from the power applying unit 50 to the internal conductor 30.

The electrode unit 40 is electrically connected to the internal conductor 30 through a cable or a wire connected to the internal conductor 30, (30).

When the internal conductor 30 receives a current of a high voltage from the electrode unit 40, the internal conductor 30 is energized with a high voltage current, and the dielectric 10 and the external conductor 20 A discharge is generated.

The air in the space in which the external conductor 20 is located is oxidized by the discharge occurring between the dielectric 10 and the external conductor 20 to oxidize the contained substance contained in the air, .

Meanwhile, the internal space of the dielectric 10 may be filled with a specific gas such as an inert gas having a weak reactivity, filled and then closed. This may be formed to have such a configuration for improving discharge efficiency.

In other words, a high-voltage current is supplied in a state where the internal conductor 30 is placed in the atmosphere, so that a gas such as an inert gas is supplied to the outside of the dielectric 10 and the external conductor 20 A high voltage current is supplied in a state of being placed in the sealed closed space, whereby more discharge is generated between the dielectric 10 and the outer conductor 20.

Hereinafter, the operation of the air purifier using the atmospheric pressure dielectric barrier discharge according to the present invention will be described.

A high-voltage current is applied to the power applying section 50 by the user's operation. When power is applied to the power applying unit 50, the power applying unit 50 transmits a high voltage current to the electrode unit 40.

At this time, a current having an AC high voltage is applied to the power applying unit 50, and a current having an AC high voltage is applied to the power applying unit 50, so that a user does not need an AC and DC conversion, I have.

In other words, when a current having a high DC voltage is applied to the power applying unit 50, it is necessary to further convert the DC high voltage to the AC high voltage, thereby limiting the current supply and utilization.

When a high voltage current is transmitted to the electrode unit 40, a high voltage current is supplied to the inner conductor 30 connected to the electrode unit 40 and a high voltage current supplied to the inner conductor 30 A discharge phenomenon occurs between the dielectric 10 and the external conductor 20. [

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. Modifications will be possible.

An air purifier using an atmospheric pressure dielectric barrier discharge according to the present invention is equipped with an inner conductor and an outer conductor in a tube-shaped dielectric having an inner space. A high-voltage current is supplied to the inner conductor of the air purifier to generate a dielectric barrier discharge, and the generated air is purified by oxidizing the contained substance in the air using the generated discharge.

According to the present invention, safety is improved by spatially separating a space in which an internal conductor to which a high voltage current is applied and a space in which a discharge occurs, and the configuration of an air purifier having various sizes from small size to large size This has the advantage.

In addition, there is an advantage that the cost required for maintenance and use of the air purification apparatus is reduced, and the efficiency of air purification is improved.

Because of these many advantages, the air purifier using the atmospheric pressure dielectric barrier discharge according to the present invention is highly applicable not only to the production industry of the air purifier but also to various related industries.
