BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrostatic precipitator, and more particularly, to an electrostatic precipitator for oil-containing gas treatment that can remove oil spots deposited on the surface of the dust collecting electrode plate during the treatment of the oil-containing gas.

Electrostatic precipitator is a device for purifying the gas by separating and collecting particulate contaminants contained in the gas using electric power, and is widely used because of its simple configuration and low maintenance cost. The gas targeted by the electrostatic precipitator is mainly air, and the gas may contain various kinds of pollutants depending on the environment in which the precipitator is installed.

However, the removal method is limited to dust collected mainly, and when the refined oil component is contained as a pollutant such as a gas containing oil droplets, the remains are collected on the surface of the collecting electrode. There is a problem in that such a removal method is difficult to apply because it forms a grease.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and only the embodiments make the disclosure of the present invention complete, and the general knowledge in the art to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, the invention is defined only by the claims. Like reference numerals refer to like elements throughout the specification.

In the present invention, the term “oil oil” referred to in the specification may be made of only an oil component, or may be made of a fine dust or the like that may be suspended in the air and mixed with an oil component.

Hereinafter, an electrostatic precipitator for oil-containing gas treatment according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 10.

1 is a perspective view showing the structure of the electrostatic precipitator for oil-containing gas treatment according to an embodiment of the present invention, Figure 2 is a schematic view showing the operating principle of the electrostatic precipitator of FIG.

Referring to FIG. 1, the electrostatic precipitator 1 for oil repellent gas treatment may be largely composed of a discharge unit 100 including a discharge electrode 110 and a dust collection unit 200 including a dust collecting electrode plate 210. Can be. Each of the discharge electrode 110 and the collecting electrode plate 210 may be formed in a unit form of an independent unit and installed in the housing 300. The discharge unit 100 and the dust collecting unit 200 are disposed to be spaced apart from each other within the housing 300, and thus, the discharge electrode 110 and the dust collecting electrode plate 210 are spaced apart from each other with a predetermined interval therebetween. Can be. A duct 310 may be connected to one side and the other side of the housing 300 in which the discharge unit 100 and the dust collecting unit 200 are disposed, and the gas to be treated is discharge unit 100. And it may serve to form a gas circulation path to be sequentially passed to the dust collecting unit 200.

The discharge unit 100 includes a discharge electrode 110 and a corresponding electrode 120 disposed adjacent to each other with the discharge electrode 110 interposed therebetween. When a high voltage is applied between each electrode, the discharge electrode 110 and the corresponding electrode 120 are charged with different polarities, and due to the rapid potential change occurring around the discharge electrode 110, the surroundings of the discharge electrode 110 are caused. The gas passing through is ionized. To this end, the discharge electrode 110 may be formed in a characteristic shape. The discharge electrode 110 may be formed, for example, in the shape of a linear, rod, or probe, and the corresponding electrode 120 may be formed in a flat plate shape. In the drawings, a rod-shaped discharge electrode 110 and a plate-shaped counter electrode 120 are illustrated, and each counter electrode 120 is illustrated in a form in which an upper end thereof is connected to each other.

The dust collecting unit 200 includes a dust collecting electrode plate 210 disposed in parallel to the vertical direction and spaced apart from each other inside the frame 240, and an oil removing bar 230 disposed between the dust collecting electrode plate 210. Include. The oil removing bar 230 is in close contact with the surfaces of the dust collecting electrode plates 210 having different side ends, respectively, and moves between the dust collecting electrode plates 210 to remove oil spots deposited on the surface of the collecting electrode plates 210. can do. The oil removing bar 230 may be connected to and supported by the support part 231 positioned at the outer side of the dust collecting electrode plate 210, and the support part 231 may be a guide part 241 formed on one side of the frame 240. Slidably coupled to). Therefore, the oil removal bar 230 is moved up and down by moving with the support 231.

Adjacent dust collecting electrode plates 210a and 210b are charged with opposite polarities. To this end, one of the neighboring collecting electrode plates 210a and 210b may be connected to the conductive bar 220a connected to the positive pole of the DC power supply, and the other may be connected to the conductive bar 220b connected to the negative pole of the DC power source. . In this case, the conductive bars connected to the positive electrode and the conductive bars connected to the negative electrode are arbitrarily divided to explain that the pair of conductive bars 220a and 220b are connected to different poles of the DC power, respectively, and are not fixed. The DC power supply may be a power supply battery formed independently of the electrostatic precipitator 1, or an AC current supplied from the outside of the electrostatic precipitator 1 may be converted into a DC current by a converter.

The pair of conductive bars 220a and 220b respectively connected to the positive electrode and the negative electrode may cross the upper ends of the dust collecting electrode plates 210. The dust collecting unit 200 and the oil removing bar 230 will be described later in more detail.

The driving unit 250 is formed at one side of the frame 240. The driving unit 250 serves to transfer the driving force to the support 231 and the oil removal bar 230 to move. Since the driving unit 250 is provided, the oil removal bar 230 may be automatically moved inside the housing 300 to perform the cleaning operation, and the dust collecting electrode plate 210 should be separated separately for the cleaning operation. Discomfort can be eliminated.

The electrostatic precipitator 1 having such a structure can be used to treat gas containing oil droplets. Oil droplets in the present specification refers to an oil component as fine particulate contaminants. Ruins can be produced in a variety of places, from refinery plants that handle crude oil and by-products thereof, to restaurants that handle large amounts of oily foods such as pork belly, and mixed with air to produce gas containing ruins. Such gases are dangerous because of the high possibility of ignition and may cause discomfort or harmful effects on the human body as they come into contact with the skin or enter the body through the respiratory tract. Electricity can be used to easily treat gases containing these remains.

Referring to FIG. 2, the gas introduced into the housing 300 through the duct (310 of FIG. 1) first passes through the discharge electrode 110. (The gas advances in the direction of the arrow.) The gas before passing through the discharge electrode 110 includes an electrically neutral oil drop d1. When the gas passes through the discharge electrodes 110, the aforementioned ionization phenomenon occurs around the discharge electrodes 110. The ionization phenomenon occurs as the electrons inside the gas molecules experience a sudden electric potential change and are discharged while passing through an unevenly distributed electric field around the discharge electrode 110. The ionization phenomenon may be due to corona discharge, one of such discharge phenomena.

Remains d2 inside the ionized gas are charged and interact with the discharged electrons. At this time, the discharge and charging phenomenon occurs without affecting the flow of the gas, the gas including the charged oil (d2) is moved toward the dust collecting electrode plate (210).

Electric fields uniformly formed in a direction perpendicular to each electrode plate are distributed between the collecting electrode plates 210, and the remains d3 are moved in a direction perpendicular to the gas gas under the influence of the electric field, thereby collecting the collecting electrode plate 210. Is attached to the surface. At this time, the remains d3 charged with different polarities may be moved to the dust collecting electrode plates 210 having opposite polarities, respectively.

Through this process, it is possible to separate and collect the remains from the gas containing the remains. At this time, the oil remains d3 are deposited on the collecting electrode plate 210 to form an oil stain on the surface of the collecting electrode plate 210. Such oils have a high viscosity and are difficult to be removed by a chase method or a cleaning method. The oil removing bar disposed between the dust collecting electrode plates 210 and in close contact with the dust collecting electrode plates 210 may be very effective in removing such oil spots.

Hereinafter, the dust collecting unit and the oil removing bar will be described in more detail with reference to FIGS. 3A to 8.

3A and 3B are front and plan views of a dust collecting unit of the electrostatic precipitator of FIG. 1, and FIGS. 4A and 4B are diagrams illustrating a collecting electrode plate and a modification thereof of the dust collecting unit of FIG. 3A.

3A and 3B, when the dust collecting unit 200 is based on the drawing, the frame 240 is formed at both left and right sides of the dust collecting unit 200, and is perpendicular to the inner side (internal space between the frames) of the frame 240. A plurality of dust collecting electrode plates 210 are disposed parallel to each other in one direction. The frame 240 and the collecting electrode plate 210 may be formed in parallel to each other in the vertical direction. On the contrary, the conductive bars 220 are aligned in the horizontal direction and intersect the upper ends of the collecting electrode plates 210, and when viewed from the top of the dust collecting unit 200, as shown in FIG. 3B, the conductive bars 220 may be arranged in parallel with each other. Can be. Each of the conductive bars 220a and 220b may be connected to the positive electrode and the negative electrode of the DC power source to charge the dust collecting electrode plates 210a and 210b to have different polarities.

The conductive bars 220a and 220b parallel to each other may be coupled to any one of the collecting electrode plates 210a and 210b adjacent to each other. At this time, one conductive bar 220a is bypassed without contacting an end of the uncoupled collecting electrode plate 210b and is coupled to the coupling hole (see 212 of FIG. 4A) of the neighboring collecting electrode plate 210a. Such a coupling process may be repeated, and through this, the collecting electrode plates 210a and 210b may be alternately coupled to the conductive bars 220a and 220b connected to the anode or the cathode, respectively. Each of the collecting electrode plates 210a and 210b has an end portion formed of a cutout portion (see 211 of FIG. 4A) formed by cutting a portion of the collecting electrode plate, so that contact with an uncoupled conductive bar can be easily avoided, and the conductive The bar may be coupled to the other by bypassing the cutout 211 of any one of the neighboring collecting electrode plates 210a and 210b.

4A and 4B, neighboring collecting electrode plates 210a and 210b may be formed to be inverted to be symmetrical with each other, and the coupling hole 212 and the cutout 211 may be formed at upper edge portions thereof. Can be formed on.

Meanwhile, referring to FIG. 4B, a portion of the upper end of the dust collecting electrode plate 210-1 may be cut to form the accommodating part 213. The accommodating part 213 is formed by cutting a part of the collecting electrode plate 210-1 to avoid a point where the coupling hole 212 is formed, and the respective collecting electrode plates 210-1a and 210-1b are parallel to each other. When disposed, it may be formed as a three-dimensional empty space between the conductive bar (refer to 220 of FIG. 1) coupled to the coupling hole 212. The accommodating part 213 formed as described above may contain an oil removing bar. This will be described later in more detail.

5A to 5C are diagrams illustrating an oil removing bar and a modification thereof of the dust collecting unit of FIG. 3A, and FIG. 6 is a plan view illustrating an oil removing bar and a supporting part of the dust collecting unit of FIG. 3A.

5A to 5C, a plurality of oil removal bars 230 are disposed in the spaces between the plurality of dust collecting electrode plates 210, respectively. The oil removing bar 230 has both side ends closely contacted with surfaces of the different dust collecting electrode plates 210. In this case, when one dust collecting electrode plate 210 is placed therebetween, different oil removal bars 230 are in contact with one side and the other side of the collecting electrode plate 210, respectively, on one side and the other side. One end and the other end of the different oil removal bar 230 in contact with each other is located at the opposite portion (points facing each other) of the collecting electrode plate 210. Therefore, the oil removal bar 230 is pressed to each side end portion of the dust collecting electrode plate 210 facing each other. Due to this pressing effect, the oil removing bar 230 may be in close contact with the dust collecting electrode plate 210 more effectively, and may easily remove oil stains while moving along the dust collecting electrode plate 210.

Deoiling bar 230 may be formed into various shapes that can effectively remove the oil. The oil removing bar 230 may be formed such that the thickness thereof becomes slightly convex as the thickness gradually decreases from the center toward both side ends as shown in FIG. 5A. At this time, both side end portions having a relatively thin thickness may effectively act to remove the grease while being elastically deformed in contact with the surface of the collecting electrode plate 210.

In addition, as shown in Figure 5b, the oil removal bar 230a is gradually reduced in thickness from the center toward both side ends, but the thickness of the upper and lower portions are formed asymmetrically, that is, in the opposite direction of gravity One flat portion 232 connecting both side ends may be formed. When formed in such a shape, both side ends of the oil removing bar 230a may be in close contact with the surface of the dust collecting electrode plate 210 when the oil removing bar 230a is moved downward. Scraping down grease can be more efficient.

Meanwhile, as shown in FIG. 5C, linear protrusions 233 may be formed at both side ends of the oil removing bar 230b. One or more linear protrusions 233 may protrude in a direction perpendicular to the collecting electrode plate 210, and each of the linear protrusions 233 may be in close contact with the surface of the collecting electrode plate 210 at the same time. It is possible. When the linear protrusion 233 is formed, the thickness of the oil removal bar 230b may be formed to be thicker.

Referring to FIG. 6, the oil removing bar 230 may be connected to the support part 231. The support part 231 may be formed to be connected to an end portion which is not in close contact with the dust collecting electrode plate 210 of the oil removing bar 230, and the plurality of oil removing bars 230 may be disposed on the same plane. It may be formed in a shape surrounding the outer portion of the removal bar 230. The support 231 may be formed with a holder 234 having a groove shape at the left and right edges of the drawing. The support part 231 may be slidably coupled to the guide part (see 241 in FIG. 1) formed at one side of the frame (see 240 in FIG. 1) using the holder 234, and may be along the guide part 241. Up and down movement is possible with the oil removal bar 230. In addition, a rack holder 235 having a wider width than the holder 234 may be formed at one side of the edge portion of the support 231. Using the rack holder 235, the support 231 may be slidably coupled to a rack (see 253 of FIG. 1) formed on the other side of the frame 240.

7 is a perspective view illustrating a modified example of the oil removing bar and the support of FIG. 6.

As shown in FIG. 7, the oil removal bar 230 and the support 231 are not formed on the same plane as each other, and the oil removal bar 230 may be three-dimensionally formed such that the oil removal bar 230 is located above the support 231. Can be. At this time, the support 231 and the oil removal bar 230 may be connected by a connection part 236 connecting one side of the support 231 and one side of the oil removal bar 230 without being directly connected to each other. The connection part 236 extends from the support part 231 and may be elevated toward the oil removal bar 230 while refracting at least once, and may be formed to have a narrow bar shape or a wire shape. In the drawing, a curved bar-shaped connection portion 236 narrower than the oil removal bar 230 is shown.

Due to this three-dimensional shape, the oil removal bar 230 may be lifted together with the support part 231 to be separated from the upper end of the dust collecting electrode plate (see 210-1 of FIG. 4B), and after the separation, the accommodating part ( (See 213 in FIG. 4B).

8 is a side view illustrating a driving unit of the electrostatic precipitator of FIG. 1.

Referring to FIG. 8, the driving unit 250 may include a rack device, which is a kind of linear motion transfer means consisting of a rack 253 and a pinion gear 252, and a driving motor 251 serving as an actuator. . The rack 253 is formed in a vertical direction on one side of the frame 240, the drive motor 251 and the pinion gear 252 may be mounted on one side of the support 231. At this time, the pinion gear 252 and the rack 253 may be in contact with each other inside the rack holder described above.

When the driving motor 251 is driven, the pinion gear 252 is rotated so that the entire support part 231 moves along the rack 253. At this time, the rising or lowering rack device is moved in the direction of gravity or the opposite direction of gravity. The drive motor 251 and the pinion gear 252 may be connected by a chain, although not shown in the figure, between the drive motor 251 and the pinion gear 252 is a compact gearbox for adjusting the rotational speed of the gear Can be installed further. As shown in FIG. 1, the rack device is formed to have the same length as the length of the collecting electrode plate along the side of the frame 240, so that the height of the housing (see 300 of FIG. 1) or the frame 240 is increased. It may be the same as the case in which it is arranged alone, the length of the rack device may be shorter than the length of the collecting electrode plate if the oil removal bar is located above the support portion 231 as described above, the device is compact Can be configured. Accordingly, even if the driving unit 250 is installed, the size of the entire electrostatic precipitator does not need to be greatly increased as compared to the past, and it is possible to install and use the electrostatic precipitator in the existing installation place without difficulty. The drive unit 250 may be configured using a ball screw device or a belt device as well as a rack device.

9A to 10B, the operation of the electrostatic precipitator for oil-containing gas treatment will be described in more detail.

 9A and 9B, the oil removal bar 230 moves in the direction of gravity or in the opposite direction of gravity to reciprocate between the collection electrode plates 210 and scrape off the grease A formed on the collection electrode plates 210. Remove When the oil removal bar 230 moves upward in the opposite direction of gravity from the lower side of the dust collecting electrode plate 210 as shown in FIG. 9A, the oil stain A may be pushed upward and separated from the dust collecting electrode plate 210. 9b, when the oil removal bar 230 moves downward in the gravity direction from the dust collecting electrode plate 210 and descends, the oil stain A is pushed downward and separated from the dust collecting electrode plate 210. Can be. At this time, when the oil drop (A) separated from the collecting electrode plate 210 can be dropped by gravity when falling, the collection unit 400 for collecting the oil (A) below the dust collecting electrode plate 210. Can be formed. The collecting part 400 may be formed by deforming the bottom part of the housing, or may be formed independently of the housing and coupled to the bottom of the housing to be detachable. Collector 400 may be formed with a discharge port 410 in the central portion so that the oil (A) can be discharged.

The reciprocating process of the oil removal bar 230 may be performed in a set of ascending and descending processes, and the ascending process may be a preliminary process for scraping down the grease (A) in the gravity direction while descending. In this way, when the oil removal bar 230 is operated, the rising and falling speeds of the oil removing bar 230 may be different from each other. It can be shaped to scrape off.

Subsequently, referring to FIGS. 10A and 10B, the oil removing bar 230 formed to be positioned upward from the support part 231 by the connecting part 236 is raised together with the support part 231 while collecting the collecting electrode plate 210-. The upper end of 1) may be accommodated in the accommodating part 213. At this time, the support 231 may be raised to a position where the oil removal bar 230 is separated from the dust collecting electrode plate 210-1 along the frame.

You will not. In addition, the dust collecting electrode plates 210-1 may be energized with each other to prevent a charge that may not be charged with a different polarity or a short circuit in advance, thereby ensuring the original function of the electrostatic precipitator. When the oil removal bar 230 is made of a metal material, it is possible to secure the stability and safety of the electrostatic precipitator through this design.

Referring to FIG. 11, in the electrostatic precipitator for oil repellent gas treatment according to another modified example of the present invention, both side ends of the oil removing bar 230 are rotated in opposite directions with respect to the rotation axis to be in close contact with each other. It may be formed to be spaced apart from the surface of the electrode plate (210). Preferably, the oil removal bar 230 may be spaced apart and rotated to a position parallel to the dust collecting electrode plate 210.

At this time, the rotating shaft 237 is located between both side ends of the oil removal bar 230, is formed along the longitudinal direction of the oil removal bar 230. In the drawing is shown a rotating shaft 237 protruding from the central portion of the end portion that is not in contact with the dust collecting electrode plate 210 of the oil removal bar 230. Rotating shaft 237 is rotatably coupled to one side of the support 231 may be rotated with the oil removal bar 230.

The rotation direction in which both side ends are rotated may be adjusted by the direction control link 260 disposed in the horizontal direction along the support part 231. Directional link 260 is connected to the oil removal bar 230, is connected to the one point spaced apart from the rotating shaft 237 to the torsional force to the rotation axis 237 to the center of rotation to the oil removal bar 230 Can be generated. In order to smoothly rotate, the oil removal bar 230 and the direction control link 260 may be connected to each other in a hinged manner to the protrusion 238 protruding from the one point, coupled with the protrusion 238 One side of the direction control link 260 is a hinge portion 261 may be formed for this purpose.

One end of the direction control link 260 may be coupled to the guide rail (270). The guide rails 270 are disposed parallel to each other in parallel with the dust collecting electrode plate 210, and spaced apart from the oil removing bar 230 at regular intervals. Thus, the direction control link 260 is interposed between a point of the oil removal bar 230 and the guide rail 270, the guide rail 270 when the oil removal bar 230 is moved. Can move together. The guide rail 270 may be a groove formed along one side of the frame 240, and the direction control link 260 may be a guide rail using an insertion part 262 inserted into the groove-shaped guide rail 270. 270 can be slidably coupled.

The guide rail 270 extends in the vertical direction in parallel with the dust collecting electrode plate 210 and is refracted to one side near the upper end of the frame 240 to form the refracting portion 271. Accordingly, the direction control link 260 moving along the guide rail 270 may be driven in a direction perpendicular to the collecting electrode plate 210 by changing the trajectory at the point where the refracting portion 271 is formed.

12A to 12C, the driving of the direction control link will be described in more detail.

As described above, the direction control link 260 moves up and down with the oil removal bar 230 while being disposed in the horizontal direction. Since the guide rail 270 is formed in the vertical direction along the dust collecting electrode plate 210, the direction control link 260 may be moved to the vicinity of the upper end as shown in FIG. 12A without changing the horizontal position.

However, when the insertion portion 262 of the direction control link 260 enters the bend portion 271 as shown in FIG. 12B, the direction control link 260 rises and changes in a horizontal position at the same time. Through this, the direction control link 260 can be driven in a direction perpendicular to the dust collecting electrode plate 210, it can generate a torsional force to rotate the oil removal bar 230 by this drive.

As shown in FIG. 12C, when the direction control link 260 is completely moved along the refraction portion 271, both side ends of the oil removing bar 230 are completely spaced apart from the dust collecting electrode plate 210. Can be aligned in a direction parallel to

Therefore, when the oil removal operation is completed, the oil removal bar 230 may be naturally switched to the standby state in which the contact with the collecting electrode plate 210 is released, and the collecting electrode plates 210 are energized with each other in the standby state. It may be prevented, and may not interfere with the flow of gas flowing between the dust collecting electrode plate 210.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
