Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram briefly showing an odor removing device according to an embodiment of the present invention.

Referring to the drawings, the odor removing device 100 of FIG. 1 includes a plasma generating unit 110 and a filter unit 120.

The plasma generating unit 110 is disposed on a flow path of air containing an odorous substance, and generates a plasma by an applied voltage.

The plasma generation unit 110 includes a dielectric attached to at least one of a first electrode and a second electrode, and a first electrode and a second electrode, which face each other to form a discharge space. A high frequency high voltage having a frequency of several hundred kHz and having a voltage of several hundred volts or more is applied between the first electrode and the second electrode, so that plasma is generated in the air layer between the discharge spaces. Anion generated by the plasma is combined with the odorous substances in the air introduced through the inlet 155 to perform deodorization. Detailed description of this plasma generating unit 110 will be described later with reference to FIGS. 4 to 6.

The filter unit 120 filters the ions attached to ozone and odorous substances generated by the plasma.

The filter unit 120 may include active carbon and manganese dioxide (MnO 2). In addition, the filter unit 120 includes at least one of iodine (I), silver (Ag), aluminum (Al), manganese (Mn), zinc (Zn), iron (Fe), lithium (Li), and calcium (Ca). It may be formed to include one more. The filter unit 120 may be implemented in a powder form including active carbon, manganese dioxide (MnO 2), and the like.

By the filter unit 120 including the activated carbon, manganese dioxide (MnO 2), and the like, the odorous substance attached to the ions through the plasma generator 110 and the plasma generator 110 Ozone (O3), nitrogen oxides (NOx) generated as a by-product can be effectively removed.

Specifically, ozone (O3) generated as a by-product from the plasma generating unit 110 is destroyed by the strong adsorption force of the activated carbon of the filter unit 120. In addition, nitrogen monoxide (NO) generated as a by-product from the plasma generating unit 110 is easily combined with oxygen on the surface of the filter unit 120 to be changed to nitrogen dioxide (NO 2), which is again in the form of nitric acid (HNO 3). Will accumulate. Since the amount of nitrogen compounds, such as nitrogen monoxide (NO), generated as a by-product from the plasma generating unit 110, is generated about 0.01 times as compared with ozone (O3) generated together, the influence is small.

As described above, air in which odorous substances, ozone, and nitrogen oxides are significantly removed through the filter unit 120 is discharged to the outside of the odor removing device 100 through the outlet 165.

Various arrangements of the filter unit 120 will be described later with reference to FIG. 2, and a description of the structure of the filter unit 120 will be described later with reference to FIG. 3.

FIG. 2 is a view schematically illustrating various layouts of the filter unit in the odor removing device of FIG. 1.

Referring to the drawings, FIGS. 2A to 2C show various arrangements of the filter portion.

First, FIG. 2 (a) shows that the filter unit 120 is formed at the rear end of the plasma generator 110. When air containing an odorous substance is introduced through the air inlet 155, the odorous substance is attached to ions generated through the plasma generating unit 110 to perform deodorization, and ozone and nitrogen oxides generated as by-products by plasma. Is removed through the filter unit 120. Air passing through the filter unit 120 is discharged to the outside through the outlet 165.

Next, FIG. 2B shows that the filter units 120-1 and 120-2 are formed at both ends of the plasma generator 110.

Air containing an odorous substance is firstly deodorized through the first filter unit 120-1, and secondly deodorized through the plasma generation unit 110, and the plasma generation unit through the second filter unit 120-2. Ozone and nitrogen oxides generated at 110 are removed.

Next, FIG. 2 (c) shows that the plasma generator is arranged to surround the plasma generator.

Since the filter unit 120 is formed to surround the plasma generator 110, similarly to FIG. 2 (b), air containing an odorous substance is firstly deodorized, and the plasma generator 110 is discharged through the plasma generator 110. The car is deodorized and removes ozone and nitrogen oxides generated by the plasma generator 110.

The filter unit 120 shown in (a) to (c) of Figure 2 can be immediately deodorized, a large capacity deodorization is also possible. In addition, the filter unit 120 and the plasma generator 110 may be integrated to implement an odor removing device in a module form.

3 is a view showing an example of the structure of the odor removing device of FIG.

Referring to the drawings, the plasma generating unit 310 and the filter unit 320 of the odor removing device 300 of Figure 3 may be formed in a cylindrical shape.

A hollow is formed in the filter 320, and the plasma generator 310 may be disposed in the hollow. In the figure, it is shown that plasma is generated in the hollow.

Meanwhile, the outside of the filter unit 320 may be formed in a mesh shape, and the filter unit 320 may be covered by the upper case 335 and the lower case 340 to seal the plasma generator 310.

Although not shown in the figure, a cable may be connected to apply a high voltage to the first electrode and the second electrode of the plasma generator 310 sealed by the filter unit 320.

Meanwhile, the hollowness in the filter part 320 may be formed in a mesh shape in the same manner as the outside of the filter part 320. When the filter unit 320 is formed in such a mesh form, air containing an odorous substance is introduced into the plasma generator 310 through the lower portion of the filter unit 320 as shown in the drawing, and deodorized from the plasma generator 310. The ozone and nitrogen oxides generated as by-products in the plasma generator 310 are removed through the filter 320 surrounding the plasma generator 310, and the filtered air is filtered. It will flow through the outside of the.

Such an odor removing device 300 can be formed as a module. In addition, it is possible to immediately deodorize and deodorize a large capacity, and the deodorizing performance is excellent, thus, it is possible to supply a relatively small voltage to the electrode of the plasma generating unit 310 as compared to the conventional.

4 is a diagram illustrating an example of the plasma generator of FIG. 1.

Referring to the drawings, the plasma generator 400 of FIG. 4 includes a first electrode 410, a dielectric 420, and a second electrode 430.

The first electrode 410 and the second electrode 430 face each other to form a discharge space 485. The first electrode 410 and the second electrode 430 may be formed in a flat plate shape as shown in the drawings. Dielectrics 420 are formed on the first electrode 410 and the second electrode 430. In the drawing, the dielectric 420 is attached to the first electrode 410, but the present invention is not limited thereto, and the dielectric may be attached to at least one of the first electrode 410 and the second electrode 430.

When a high frequency high voltage is applied between the first electrode 410 and the second electrode 430, plasma is generated in the discharge space 485 according to an electric field generated between both electrodes. The intensity of the plasma generated in the discharge space 485 is proportional to the intensity of the electric field.

Ions are generated from air by the plasma generated from the plasma generator 400. The generated ions remove odorous substances introduced through the inlet 455 by the blower 405. Deodorized air flows out through the outlet 465. As a by-product of the plasma generator 400, ozone and nitrogen oxide may also flow out through the outlet 465.

On the other hand, it may further include a case (440,445) surrounding each of the first electrode 410 and the second electrode 430.

5 is a diagram illustrating an example of the plasma generator of FIG. 1.

Referring to the drawings, the plasma generator 500 of FIG. 5 is almost similar to the plasma generator 400 of FIG. 4. However, unlike in FIG. 4, the plasma generator 500 of FIG. 5 has a difference in that the protrusion 535 is formed in the discharge space direction in the second electrode 530. Therefore, descriptions of the first electrode 510, the dielectric 520, the second electrode 530, the blower 505, the inlet 555, the outlet 565, and the cases 540 and 545 are described with reference to FIG. 4. Reference is omitted.

The protrusion 535 is formed on the second electrode 530 toward the discharge space 585. The protrusion 535 may be formed in plural on the second electrode 530.

End portions of the plurality of protrusions 535 and the dielectric 520 are spaced apart from each other, but are set to be less than a set interval. The closer the setting interval is, the greater the intensity of the electric field becomes, and thus the intensity of plasma generated increases. In addition, the sharper the end portion of the protrusion 535, the greater the intensity of the electric field, the greater the intensity of the generated plasma. The larger the plasma, the greater the amount of ions produced, and thus the better the removal performance of the odorous substance.

On the other hand, the plurality of protrusions 535 are spaced apart from each other. The protrusion 535 may have various shapes, for example, a polygonal pillar, a cylinder, a cone, a triangular pyramid, an end portion may be tapered or rounded, and a prism having a two-dimensional shape rather than a three-dimensional shape. It is also possible to be formed in a shape.

In addition, unlike the drawing, the protrusion 535 may be formed on at least one of the first electrode 510 and the second electrode 530 in the discharge space direction.

A description thereof will be omitted with reference to FIG. 5.

The through hole 680 is formed on the second electrode 630 to discharge the air from which the odorous substance is removed in the discharge space 685. The through holes 680 may be formed in plural on the second electrode 630. In addition, the plurality of through holes 680 may be disposed between the plurality of protrusions 635. In addition, in order to secure a contact time between the air including the odorous substance introduced into the discharge space 685 and the protrusion 635, the air containing the odorous substance may be formed at a position spaced a predetermined distance away from the side.

Meanwhile, in the drawing, as the through hole is formed on the second electrode 630, the air outlet 665 is formed in a direction perpendicular to the air inlet 655, but is not limited thereto. Can be arranged.
