[0070] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0071] Figure 1 is a schematic view of an electrostatic precipitator according to an embodiment of the present disclosure. Figure 2It is a view showing an electrostatic precipitator according to an embodiment of the present disclosure. Figure 3 It is a view showing Figure 2 an exploded view of the electrostatic precipitator shown in

[0072] Referring to Figures 1 to 3 , the electrostatic precipitator 1 may include a charging unit 10 and a dust collection unit 20 installed downstream of the charging unit 10.

[0073] The electrostatic precipitator 1 is arranged to allow air introduced into the charging unit 10 along the Figure 1 direction F shown in

[0074] to pass through the collection unit 20 by means of a blower fan (not shown) provided upstream or downstream of the electrostatic precipitator 1, and then flow to the outside.

[0075] In Figure 1 , for ease of description, the discharge electrode 11 is shown as being arranged between a pair of counter electrodes 12, but the charging unit may include a plurality of discharge electrodes and a plurality of counter electrodes alternately arranged between the plurality of discharge electrodes.

[0076] When a voltage (e.g., a voltage of 3 kV to 7 kV) is applied to the discharge electrode 11, the discharge electrode 11 and the counter electrode perform a corona discharge, which causes contaminants in the air to be charged with a positive polarity (+) or a negative polarity (-). For ease of description, an example of charging contaminants in the air passing through the charging unit 10 with a positive polarity will be described below.

[0077] The dust collection unit 20 has a structure in which a plurality of plate-shaped positive electrodes 210 and a plurality of plate-shaped negative electrodes 220 are stacked at regular intervals. For example, the positive electrode 210 and the negative electrode 220 may be formed by printing carbon ink on the surface of a laminated film, or may be formed as metal plates (such as aluminum plates).

[0078] Therefore, when a constant voltage is applied between the positive electrode 210 and the negative electrode 220 of the dust collection unit 20, an electric field is formed between the positive electrode 210 and the negative electrode 220. Here, by referring to the high-level electrode as the positive electrode and the low-level electrode as the negative electrode, the positive electrode and the negative electrode are determined based on the potential difference between the two electrodes. The positive electrode 210 may form the first electrode 210. The negative electrode 220 may form the second electrode 220.

[0079] The positively charged contaminants passing through the charging unit 10 can adhere to the negative electrode 220 of the dust collecting unit 20 while passing through the dust collecting unit 20 arranged downstream of the charging unit 10. With this configuration, the contaminants in the air can be removed. Therefore, the air passing through the dust collecting unit 20 can be discharged from the electrostatic dust collecting device 1 in a clean state with the contaminants removed from the air.

[0080] The dust collecting unit 20 may include dust collecting sheets 200 and a first cover 21 and a second cover 22 covering the dust collecting sheets 200.

[0081] The first cover 21 and the second cover 22 may be provided in a frame shape surrounding the outer periphery of the dust collecting sheets 200 and have openings 21H and 22H on their inner sides such that the air passing through the charging unit 10 passes through the dust collecting sheets 200.

[0082] A power connection member (not shown) connected to the dust collecting sheets 200 and supplying power to the dust collecting sheets 200 may be arranged on the first cover 21 and the second cover 22.

[0083] The dust collecting sheets 200 may include a plurality of electrodes stacked on one another.

[0084] Figure 4 is a view showing Figure 2 the first electrode and the second electrode of the electrostatic dust collecting device shown in Figure 5A is a view showing Figure 4 the cross section of the electrostatic dust collecting device shown in Figure 5B is a view showing Figure 4 the cross section of the electrostatic dust collecting device shown in

[0085] Referring to Figure 4 、 Figure 5A and Figure 5B The first electrode 210 may be arranged on the upper side, and the second electrode 220 may be arranged on the lower side. The support member 300 may be arranged between the first electrode 210 and the second electrode 220. The support member 300 may be arranged to maintain the interval between the first electrode 210 and the second electrode 220.

[0086] The support member 300 may be provided in at least one of the first electrode 210 and the second electrode 220. The support member 300 may be arranged to surround each of the opposite ends of the first electrode 210 and the second electrode 220 along the short sides of the first electrode 210 and the second electrode 220. That is, the support member 300 may be arranged to surround the opposite ends of the first electrode 210 and the second electrode 220 along the Y direction. Therefore, the electrode 210, the electrode 220, and the support member 300 are not easily separated from each other and can be firmly combined with each other.

[0087] At least one support member 300 may be arranged to be spaced apart from each other.

[0088] The support member 300 may be formed of an insulating material. As such, since the insulating material ensures the spacing between the first electrode 210 and the second electrode 220, insulation breakdown can be prevented.

[0089] The support member 300 may include a first support member 310 and a second support member 320. The first support member 310 may be formed such that the first electrode 210 is inserted therein. The second support member 320 may be formed such that the second electrode 220 is inserted therein.

[0090] Each of the first support member 310 and the second support member 320 may be provided in plurality.

[0091] The plurality of first support members 310 may be arranged to be spaced apart from each other in the X direction. That is, the plurality of first support members 310 may be coupled to the first electrode 210 while being spaced apart from each other in the X direction. The plurality of second support members 320 are also arranged to be spaced apart from each other in the X direction and may be coupled to the second electrode 220.

[0092] The first support member 310 and the second support member 320 may support each other and be in contact with each other such that the first electrode 210 and the second electrode 220 are stacked one on top of the other in the Z direction. That is, the lower surface of the first support member 310 may be in contact with the upper surface of the second support member 320, and the lower surface of the second support member 320 may be in contact with the upper surface of another first support member 310 among the plurality of first support members 310.

[0093] Air for removing aerosol may pass through the region between the first electrode 210 and the second electrode 220 in the Y direction.

[0094] Figure 6A It is a view showing Figure 2 the support member of the electrostatic precipitator shown in Figure 6B It is a view showing the support member of the electrostatic precipitator according to another embodiment of the present disclosure. Figure 7A It is a view showing the support member of the electrostatic precipitator according to still another embodiment of the present disclosure. Figure 7B It is a view showing the support member of the electrostatic precipitator according to still another embodiment of the present disclosure;

[0095] Referring to Figure 6A 、 Figure 6B 、 Figure 7A and Figure 7B the support member may include a main body 301 and an electrode insertion part 302.

[0096] The main body 301 may include a coupling hole 301a formed to be coupled to the support bar 330. The coupling hole 301a may pass through the main body 301 along the Z direction. Accordingly, the support bar 330, which will be described below, may be coupled to the coupling hole 301a of the at least one support member 300, thereby connecting the support bar 330 to the first electrode 210 and the second electrode 220. The coupling hole 301a is shown in a cylindrical shape, but is not limited thereto, and may be formed corresponding to the shape of the support bar 330. Accordingly, the coupling hole 301a may include various other shapes in addition to the cylindrical shape, as long as it can be coupled to the support bar 330.

[0097] Referring to Figure 6B , the main body 301 may further include an assembly hole 301b connected to the coupling hole 301a. The assembly hole 301b may be formed such that the support bar 330 is coupled to the coupling hole 301a through the assembly hole 301b. That is, the support bar 330 may be assembled into the assembly hole 301b.

[0098] Due to the coupling hole and the support bar, the at least one support member and the electrode may be stably stacked, and the process may be simplified, so that the manufacturing cost may be reduced.

[0099] The electrode insertion part 302 may include an upper part 302a, a lower part 302b, and an electrode insertion groove 303.

[0100] The upper part 302a and the lower part 302b may be formed to protrude from the main body 301 along the Y direction. The electrode insertion groove 303 may be provided between the upper part 302a and the lower part 302b. The electrode insertion groove 303 may be formed such that the first electrode 210 or the second electrode 220 is inserted and assembled thereon. In the drawings, the electrode insertion groove 303 is shown in a quadrilateral shape, but is not limited thereto, and may be formed in a shape corresponding to the end of the electrode. Accordingly, the electrode insertion groove 303 may also include a circular shape. In addition, the position of the electrode insertion groove 303 is shown in the middle between the upper part 302a and the lower part 302b, but is not limited thereto, and the electrode insertion groove 303 may be formed on one side adjacent to the upper part 302a or the lower part 302b.

[0101] Each of the support members 300 may further include a fixing device 306 for fixing the electrode inserted therein. The fixing device 306 may further include an adhesive member 306a and a hook 306b. Due to the fixing device 306, the coupling between the electrode and the support member 300 may be prevented from being easily released.

[0102] The adhesive member 306a may be formed on the surface adjacent to the electrode insertion groove 303 in the electrode insertion part 302. The adhesive member 306a may be formed in a shape corresponding to the electrode insertion groove 303. That is, the adhesive member 306a may be disposed at the portion of the electrode insertion part 302 that contacts the electrode.

[0103] The hook 306b can protrude from the upper part 302a or the lower part 302b of the electrode insertion part 302 in the direction toward the electrode insertion groove 303. In the drawings, the hook 306b is shown as protruding from the upper part 302a along the Z direction, but is not limited thereto, and can protrude from the lower part 302b along the Z direction. When the hook 306b is formed on the support member 300, the first electrode 210 and the second electrode 220 can be formed with grooves having a shape corresponding to that of the hook 306b. The shape of the hook 306b is not limited to the shape shown in the drawings and can include various shapes.

[0104] Figure 8A is a view showing a support member of an electrostatic precipitator according to still another embodiment of the present disclosure. Figure 8B is a view showing a support member of an electrostatic precipitator according to still another embodiment of the present disclosure. Figure 9A is a view showing Figure 8A a cross-section of the electrostatic precipitator device shown in FIG. when viewed in the X direction.

[0105] Figure 9B is a view showing Figure 8A a cross-section of the electrostatic precipitator device shown in FIG. when viewed in the Y direction.

[0106] Referring to Figure 8A 、 Figure 8B and FIG. 9, the electrode insertion groove 303 can be formed in at least one unit of the electrode insertion groove. That is, at least one electrode insertion groove 303 can include a first electrode insertion groove 303a and a second electrode insertion groove 303b. The first electrode insertion groove 303a and the second electrode insertion groove 303b can each be coupled to the first electrode 210 or the second electrode 220. For example, the first electrode 210 can be inserted into the first electrode insertion groove 303a, and the second electrode 220 can be inserted into the second electrode insertion groove 303b. Conversely, the first electrode 210 can be inserted into the second electrode insertion groove 303b, and the second electrode 220 can be inserted into the first electrode insertion groove 303a. Since both the first electrode and the second electrode can be inserted into one support member, the number of support members can be reduced, and the management of the support members can be facilitated.

[0107] An intermediate part 302c can be formed between the first electrode insertion groove 303a and the second electrode insertion groove 303b.

[0108] Each of the support members 300 may further include a guide protrusion 304 and a guide groove 305. The guide protrusion 304 and the guide groove 305 may extend along the Z direction from the electrode insertion part 302. The guide protrusion 304 may be formed to protrude from the upper part 302a, and the guide groove 305 may be formed to be recessed from the lower part 302b. However, the present disclosure is not limited thereto, and the guide protrusion 304 may protrude from the lower part 302b, and the guide groove 305 may be recessed from the upper part 302a.

[0109] The guide protrusion 304 and the guide groove 305 may be formed to correspond to each other. The guide protrusion 304 and the guide groove 305 are shown in a cylindrical shape, but are not limited thereto, and may include various shapes as long as they allow the support members 300 to be coupled to each other.

[0110] When the support members 300 are coupled to each other while being in contact with each other due to the guide protrusion 304 and the guide groove 305, the support members may be stably coupled to each other and prevented from separating from each other.

[0112] Referring to Figure 10A and Figure 10B , the support member 300 may be coupled to the first electrode 210, and the second electrode 220 may be disposed between the support members 300. That is, the support member 300 may not be coupled to the second electrode 220. However, alternatively, the second electrode 220 may be coupled to the support member, and the first electrode 210 may be disposed between the support members 300.

[0113] According to the above embodiment, the interval between the electrodes can be maintained with a small number of support members 300, so that the material cost can be reduced.

[0114] The air for removing the aerosol may pass through the region between the first electrode 210 and the second electrode 220 along the Y direction.

[0116] Referring to Figure 11 and Figure 12, a dust collection unit can be formed by installing the support rod 330 on the dust collection housing 340 and then alternately stacking the first electrode 210 and the second electrode 220 one on top of the other. In this case, the support member 300 is coupled to the first electrode 210 and the second electrode 220, and the support rod 330 can be coupled to the support member 300 through the coupling hole 301a.
