BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrostatic precipitator, and more particularly, to a wet battery precipitator capable of simultaneously washing dust, sludge, oil mist, etc. collected by the precipitator with washing water.

Generally, the dust collector purifies the polluted air flowing in one direction and discharges it in the other direction. Among them, the electric dust collector generates a high discharge voltage, and the fine particles in the neutron state are generated by "e + " or corona discharge. "e -" After the charged fine dusts are combined with each other, the charged fine dusts are collected on the '+' and '-' polarly charged dust collecting plates.

For example, the fine dust is charged to have negative electricity by the discharge voltage, and then the charged foreign matter is adsorbed and collected on the dust collecting plate to discharge clean air while passing through the dust collecting unit.

In this process, dust particles or fine dust in the air are adsorbed on the dust collecting plate, and as time passes, a large amount of particles accumulate in the dust collector, deteriorating dust collecting function and wasting electricity.

In order to prevent this situation, the existing methods are attached to the filter to filter out particles or dust at the beginning to reduce the amount of dust collection to extend the life of the dust collector or to easily remove the dust collector so that the user can easily wash it. .

However, the former method is not the ultimate method, and furthermore, both of them have a problem in that after a predetermined time, the dust collecting plate has to be separated, cleaned and reassembled.

Recently, there is also a method of blowing dust or dust stuck to the dust collecting plate by a strong blowing method, but this situation also needs periodic cleaning to the last, the effect is also limited.

4 is a detailed view of the discharge electrode of FIG. 2, FIG. 5 is a detailed view of the insulating support of FIG. 2, (a) is a front view, and (b) is a sectional view of the mouth.

First, as shown in Figures 1 and 2, the wet electrostatic precipitator of the present invention consists of a substantially cylindrical body frame (1) having upper and lower flanges (4, 4 ') at the upper and lower ends, respectively, As shown in the cross-sectional view of Figure 2, a slightly smaller cylindrical dust collecting plate 11 is embedded than the body frame, there is a predetermined gap between the cylindrical dust collecting plate 11 and the body frame (1), The upper end of the gap is open but the lower end is closed, so that the washing water is introduced from the outside through the inlet (2), and the introduced washing water fills the gap, and the extra washing water is continuously supplied to the dust collecting plate (11). Will flow along the inner surface of the

On the other hand, at the center of the body frame 1, the shaft 7, which is attached to the discharge electrode 8 in the longitudinal direction, is supported by the upper and lower covers 5, 5 '. Between the shaft 7 and the cover are interposed upper and lower insulating supports 6, 6 ′ for electrical insulation. The cover, the discharge electrode, and the insulating support will be described later with reference to FIGS. 3 to 5.

On the other hand, although the drain (3) is provided on the lower portion of the body frame (1), this is not necessarily necessary, it is preferable to be installed to facilitate the discharge of the wash water inside for repair or testing.

The member numbers 9 and 10 are firmly supported by the handle and the chimney used to carry the electrostatic precipitator, respectively, when the electrostatic precipitator 100 of the present invention is installed in the exhaust of polluted air or the chimney of a factory for the purpose of air purification. It is a support plate for.

3 shows the above-described upper and lower covers 5, 5 ′, which may be made in a boomerang or propeller shape with three branches as an example, and may be made in a tripod or tricycle shape. . This is to support the shaft 7 provided with the discharge electrode 8 in the center of the cover while passing through the polluted air and the purified air, respectively.

In the center of the cover 5, 5 ′, a central hole 54 for electric wire passage for supplying power to the discharge electrode is drilled, and a horizontal hole 53 for electric wire passage is punched in one branch. The member numbers 51 and 52 are first and second tap holes for fastening the covers 5 and 5 'to the body frame 1, respectively.

The electrode needle 81 of the pointed shape is protruded so as to cause well.

In addition, FIG. 5 shows an insulating support 6 or 6 for insulating the shaft 7 from the cover 5 and 5 'and the body frame 1 while supporting the cover 5 and 5' and the shaft 7. ') Is shown. The insulating support has a corrugated portion 62 on the outside in a normal insulator shape, and a through hole 61 through which an electric wire for supplying power to a discharge electrode passes.

6 illustrates the operation of the present invention by taking a slightly different embodiment from the first embodiment of the present invention (Fig. 2), and thus, the present embodiment (Fig. 6) and the first embodiment (Fig. 2). Is different from the upper side in the case of the first embodiment, while the lower cover 5 'same as the upper cover 5 is used to support the shaft 7 of the discharge electrode. ) Uses the chase method. That is, the lower side does not support the shaft 7 separately, but hangs the center weight 71 at the end of the shaft. When the electrostatic precipitator 100 'of the present embodiment is erected vertically, the shaft is also perpendicular to the gravity of the weight. The difference is that it stays in place.

By using the chucking method in this way, in the case of the first embodiment, there is a point that the lower insulation support 6 'and the lower cover 5' can be neatly solved, which may be caused by exposure to moisture. . However, in the case of the first embodiment there is no problem even in a place where the vibration is severe, in the case of the present embodiment may have a disadvantage that the shaft may be somewhat separated from the center position by the vibration.

The operation of the wet electrostatic precipitator of the present invention will now be described with reference to FIGS. 6 and 7. 7 shows an installation example of the wet electrostatic precipitator of the present invention.

First, as shown in FIG. 7, the wet electrostatic precipitator 100 or 100 ′ according to the present invention is bound by using a lower flange 4 ′ on an exhaust port 200 such as a factory where polluted air is discharged. The upper part of the electrostatic precipitator is connected to the conventional chimney 600 by using the upper flange (4). Preferably, exhaust blowers 300 and 300 'are installed between the electrostatic precipitator 100 or 100' and the exhaust port and / or the chimney of the present invention.

In this case, when it is difficult to purify with one electrostatic precipitator according to the amount of pollution air discharged or the degree of pollution, the two or more electrostatic precipitators 100 and 100 'may be connected in series and / or in parallel.

In this state, when the washing water is introduced into the wet electrostatic precipitator 100 or 100 'through the inlet 2, the washing water fills the space of the gap between the body frame 1 and the dust collecting plate 11, and then the dust collecting plate ( 11) Bar overflowing down the inner wall of the dust collecting plate (11), when the dust collector is upright, the entire inner wall of the dust collecting plate is naturally covered by the surface tension of the wash water. In this state, when a high-voltage discharge is caused to the discharge electrode inside the dust collector (see FIG. 6), dust or fine dust in the contaminated air is charged, so as to stick to the dust collector plate 11 which is spaced apart from the discharge electrode by a predetermined distance. In the wet electrostatic precipitator of the present invention, the washing water flowing down the inner wall of the dust collecting plate may naturally flow out of the dust collector in a downward direction along with the washing water.

In this way, the purified air is discharged to the upper side of the dust collector, the washing water containing contaminants is discharged to the lower side of the dust collector, FIG. 7 is collected in the washing water hopper 400, and the outlet valve 500 at regular intervals or in small amounts. Only through the washing water out, there is no need to clean the inside of the dust collector.

The outlet valve 500 on the drain 3 does not normally need to be operated, but only when the wash water in the dust collector needs to be completely drained for the dust collector replacement or internal repair.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.

As described above, according to the wet electrostatic precipitator according to the present invention, since the collected dust or fine dust is automatically cleaned by the washing water before sticking to the dust collecting plate inside the dust collector, there is no need to periodically clean the inside of the dust collector, Nevertheless, the performance of the dust collector can be always maintained at an optimum state.

In particular, according to the shunt type electrostatic precipitator of the second embodiment of the present invention, there is an advantage that a short circuit or short circuit problem that may occur in a wet environment can be completely solved.
