BACKGROUND OF THE
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.
The present invention is to solve the above problems of the prior art, the object of the present invention, by flowing the washing water to the dust collecting plate dust or oil mist (oilmist) or fine dust sticking to the dust collecting plate to be automatically washed by the washing water It is to provide an electrostatic precipitator.
Wet electrostatic precipitator according to an aspect of the present invention for achieving the above object, a cylindrical body frame (1); A cylindrical
Preferably, the discharge electrode (8) is attached to the shaft (7), again the shaft (7) is to be located in the center of the electrostatic precipitator through the upper cover (5) and the lower cover (5 '), or The
More preferably, the
Air purifier according to another aspect of the present invention for achieving the above object, the wet electrostatic precipitator (100, 100 ') is installed on the
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is a perspective view of an electric dust collector of an embodiment of the present invention, Figure 2 is a cross-sectional view of the mouth of the electric dust collector of an embodiment of the present invention, Figure 3 is a detailed cross-sectional view of the cover of Figure 2, (a) is a flat It is sectional drawing, (b) is BB 'line sectional drawing of (a).
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
On the other hand, at the center of the
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.

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
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
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
In this state, when the washing water is introduced into the wet
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
The
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.
