Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ion generating device for generating ozone,

The present invention relates to an ion generating device in which the generation of ozone is reduced. More specifically, the present invention relates to an ion generating device capable of reducing the generation of ozone generated when an ion is generated by generating ions in a heated state, And to an ion generating device in which ozone generation is reduced.

2. Description of the Related Art In general, an ion generating device is utilized in various air treatment apparatuses, in particular, electric dust collecting apparatuses by generating positive ions or negative ions by receiving a high voltage.

1 and 2 are views schematically showing a conventional ion generating device.

Referring to FIG. 1, an ion generating device according to a diffusion charging scheme is schematically shown. In this method, when a high voltage is applied to the side of the ion generating part 10 by the high voltage applying part 20, a large number of ions are emitted to the ion generating part 10 and are diffused into the air to generate ions.

According to this method, there is an advantage that ozone is not generated in the ion release process, but there is a problem that the efficiency of treating air is inferior because the amount of generated ions is small.

Referring to FIG. 2, an ion generating device according to a field charging scheme is schematically shown. The above method is the same as diffusion charging in which the ion generating part 10 is applied with a high voltage from the high voltage applying part 20 but the pair of guide parts 30).

That is, when a high voltage is applied to generate ions in the ion generating part 10, an electric field is formed between the ion generating part 10 and the guide part 30 to increase the amount of ions generated in the ion generating part 10 So that the air treatment efficiency is very good.

However, as the intensity of the voltage applied to the ion generating part 10 increases, the amount of generated ozone increases, which requires a separate means for treating ozone.

FIG. 3 is a perspective view schematically showing an ion generating device in which ozone generation is reduced according to an embodiment of the present invention, and FIG. 4 is a view schematically showing an ion generating device in which ozone generation is reduced according to FIG.

3 and 4, an ion generating device 100 in which ozone generation is reduced according to an embodiment of the present invention includes an ion generating part 110, a high voltage generating part 110 for applying a voltage to the ion generating part 110, A heating unit 140 for heating the ion generating unit 110 and a slit forming unit 130 for forming a fine slit 151 in the flow space, (150) and a compressed air supply unit (160) for supplying compressed air into the flow space.

The ion generating part 110 receives a voltage from a high voltage applying part 120 to be described later and emits positive or negative ions to the outside. The ion generating part 110 includes a body part 111 and a fiber part 112. The ion generating part 110 is disposed in the air flow space formed by the guide part 130 and is disposed in the hollow part when the guide part 130 is provided in a cylindrical shape having a hollow part. The ion generating part 110 is disposed so as to be spaced apart from the guide part 130 so that an electric field is formed between the ion generating part 110 and the guide part 130 when a high voltage is applied.

The body part 111 serves as a main frame of the ion generating part 110. The body part 111 has a fiber part 112 to be described later and is electrically connected to a high voltage applying part 120, And receives a voltage supplied from the power supply unit 120.

The fiber portion 112 is provided at an end of the body portion 111 and discharges the positive or negative ion outward when a voltage is applied from the high voltage applying portion 120. In this embodiment, the fiber portion 112 is made of a material having thermal conductivity characteristics, and may be provided with at least one of microfiber carbon fiber, microfiber metal fiber, and microbial activated carbon fiber having a diameter of several mu m to several tens of mu m . That is, unlike the conventional fiber portion 112 using the carbon fiber or metal fiber formed of the bundle, the fiber portion 112 according to an embodiment of the present invention uses the microfiber carbon fiber, the microfiber metal fiber, and the microfiber activated carbon fiber.

Accordingly, the voltage transfer rate of the conventional fiber portion 112 increases and the surface area at which ions are discharged also increases, so that the voltage applied to the ion generating portion 110 is lowered to emit the same amount of ions, It can release a larger amount of ions. In other words, by using the fiber portion 112 according to an embodiment of the present invention, the amount of generated ions can be increased more than ever.

The high voltage applying unit 120 provides a voltage to the ion generating unit 110 side. The high-voltage applying unit 120 may be provided as a means capable of providing a voltage, and may be provided with an apparatus for supplying an alternating voltage, but the present invention is not limited thereto.

The guide part 130 forms a flow space of air and has an arrangement for forming an electric field with the ion generating part 110, and the above-mentioned ion generating part 110 is disposed between the flow spaces.

The guide portion 130 is electrically grounded to form an electric field with the ion generating portion 110. At this time, the guide unit 130 may be grounded on the ground to maximize the strength of the electric field formed between the guide unit 130 and the ion generating unit 110, but is not limited thereto.

In the present embodiment, the guide portion 130 is formed in a cylindrical shape having a hollow portion so that air flows through the hollow portion. In other words, the hollow portion is a flow space, It does not.

Fig. 5 is a view schematically showing one embodiment of the heating unit in the ion generating device in which the ozone generation according to Fig. 3 is reduced, Fig. 6 is a view showing a modification example of the heating unit in the ion generating device in which ozone generation is reduced Fig.

5 or 6, the heating unit 140 heats the body part 120 while a voltage is applied from the high voltage application part 120 to generate ions on the fiber part 112 side, Thereby increasing the operating temperature of the ion generating part 110 itself.

As described above, the biggest problem in the ion generating device 100 according to the embodiment of the present invention is that ozone is generated at the same time as the generation of ions.

Here, the inventor of the present invention found through experiments that the generation of ozone is inversely proportional to the operating temperature at the time of ion release, and that the generation of ozone is remarkably reduced if the ion generating device is operated at a temperature higher than that of the conventional ion generating device .

Accordingly, by operating the ion generating part 110 in a sufficiently heated state, the amount of emitted ions can be maintained while the amount of discharged ozone can be reduced.

Referring to FIG. 5, the heating unit 140 may be provided inside the body 111, and may be provided with a heat line extending along the spiral direction. Referring to FIG. 6, the heating unit 140 may be a heating member that surrounds the outer surface of the body 111. Of course, it is needless to say that it is not limited to Fig. 5 and Fig. 6, and any means for heating the body portion 111 can be applied.

FIG. 7 is a view schematically showing an embodiment of a slit forming unit in the ion generating device in which the generation of ozone is reduced according to FIG. 3. FIG.

The slit forming unit 150 is configured to minimize the loss of ions and electrons generated in the ion generating unit 110. Referring to FIG. 7, the slit forming part 150 is disposed in the flow space and has a smaller diameter than the inner diameter of the guide part 130 to form the slit 151.

Ions and electrons generated by applying a high voltage to the ion generating part 110 are moved toward the guide part 130 by an electric field formed between the ion generating part 110 and the guide part 130. [ Accordingly, the ions, electrons, and the like generated in the ion generating part 110 must move along the flow direction, but are adhered to the guide part 130, so that a large amount of loss is lost.

Accordingly, in the present invention, a slit 151 is formed between the guide portion 130 and the slit forming portion 150 through the slit forming portion 150, thereby forming an air protecting layer on the inner wall of the guide portion 130. The adhesion of ions or electrons is prevented by the air protective layer, so that the loss is minimized.

The compressed air supply unit 160 supplies compressed air to the inside of the guide unit 130 to form an air protection layer on the inner wall of the guide unit 130. The compressed air supply unit 160 is disposed on the upstream side in the flow space to supply compressed air, and the compressed air flows along the flow space and accelerates through the slit 151. The compressed air having passed through the slit 151 flows along the inner wall surface of the guide part 130 to form an air-protecting layer.

Hereinafter, the operation of one embodiment of the ion generating device in which the aforementioned ozone generation is reduced will be described.

Before describing this, for convenience of explanation, the ion generating device 100 in which the generation of ozone is reduced according to the embodiment of the present invention is limited to the case of using in the exhaust gas treating apparatus. However, it shall not be limited to those used in such devices.

The ion generating device 100 in which the generation of ozone is reduced according to an embodiment of the present invention is installed at the inlet port side where the exhaust gas flows.

The temperature of the body portion 111 of the ion generating portion 110 is raised through the heating portion 140 before the exhaust gas is supplied to the ion generating device 100 side. That is, the ion generating part 110 itself is preheated before the ions are discharged through the ion generating part 110.

A voltage is applied to the ion generating portion 110 side through the high voltage applying portion 120 to emit ions from the fiber portion 112 side before the exhaust gas is supplied or the exhaust gas is supplied. Since the fiber portion 112 is made of microfine fiber, a large amount of ions can be generated even when a low voltage is applied as compared with the case where the fiber portion 112 is made of a conventional carbon fiber, so that power consumption can be greatly reduced. Further, the temperature of the fiber portion 112 itself is increased by the heating portion 140, and the amount of ozone generated when the ion is emitted is significantly reduced as compared with the conventional case.

The ions emitted from the fiber portion 112 side are attached to the particles included in the exhaust gas to charge the particles to have electrical properties. Here, the charged particles can be collected through an electrostatic precipitator.

Meanwhile, compressed air is supplied to the inside of the guide unit 130 through the compressed air supply unit 160. The supplied compressed air flows in the flow space along the flow direction, accelerates while passing through the slit 151, and moves along the inner wall surface of the guide part 130 to form an air-protecting layer. Therefore, it is possible to prevent ions, electrons, and the like emitted from the ion generating part 110 from being lost by being attached to the inner wall of the guide part 130 by an electric field.

Therefore, according to the present invention, there is provided an ion generating device in which the amount of generated ozone can be reduced while the amount of generated ions is increased, and the occurrence of ozone which can minimize the loss of ions and electrons is reduced.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
