It is possible to change the position of the inlet 11 and the outlet 11, It is more preferable that the outlet 13 is provided on the upper part because the specific gravity is light.

Next, the electrostatic precipitator C according to the present invention includes a plurality of discharge members 20 disposed on the air movement path between the inlet 11 and the discharge port, as shown in FIG.

When a voltage is applied to the discharge member 20, a corona discharge is generated. In this corona discharge, a large amount of electricity is discharged into the air, and the discharged electrons generate extra electrons in the process of absorbing oxygen in the air And this extra electron is often called an anion. The electrostatic precipitator C is configured such that fine particles (dust) in the air which is in contact with or directly in contact with the anion absorbs the property of electrons and is charged to the negative (-) side, and the negatively charged fine particles are positively charged The dust contained in the air is filtered by the principle that it is attracted to the dust collecting member 30 and absorbed.

Through this process, dust in the air passing through the housing 10 is adhered to the dust collecting member 30, and when the dust is adhered to the dust collecting member 30, the jetting member 40 The dust is separated from the dust collecting member 30 and precipitated to the bottom.

Next, an electrostatic precipitator (C) according to the present invention includes a dust collecting member (30) disposed adjacent to the discharging member (20) and collecting dust in the air introduced from the inlet (11).

1 and 2, it is preferable that the dust collecting member 30 is provided so as to surround the discharging member 20, because the dust collecting member 30 is adjacent to all of the plurality of discharging members 20 So as to increase the dust collecting efficiency.

In addition, the dust collecting member 30 may be formed of a circular, polyhedral, or the like, which can be variously implemented according to the choice of the practitioner or according to the standard to be used (see FIGS. 2B and 2C).

The discharge member 40 is disposed in the discharge member 20, and the dispersing member 50 guides the air that has flowed into the inlet 11 to be dispersed evenly into the plurality of discharge members 20. In this case, This configuration is a general structure of a wet electrostatic precipitator, and in the case of a dry dust collector, the jetting member 40 can be omitted.

The discharge member 20, which is a key feature of the present invention, maximizes the dust collecting efficiency through its unique structure. Hereinafter, with reference to the accompanying drawings, the structure of the discharge member 20 and its implementation I will explain.

First, the discharge member 20 according to the embodiment shown in FIG. 2 includes a polyhedron electrode 21 arranged in parallel to the moving direction of air, and a plurality of acute electrodes 21, (23). The pointed body 23 has a first pointed portion 231 protruding in one direction and a second pointed portion 232 protruding in the other direction.

1 to 4 show only the shape of the tetrahedron, that is, the shape of a quadrangular rod. However, when the electrode bar 21 is formed of the remaining polyhedrons by referring to the tetrahedron or quadrangular rod, those skilled in the art will be able to make any reference thereto. do.

2 to 4, the one direction is a direction perpendicular to the surface of the electrode 21 on which the electrode 23 is mounted (hereinafter referred to as " first direction "), Direction) and the other direction is a direction (hereinafter referred to as a second direction) that is parallel to the surface of the electrode 21 to which the first electrode 23 is attached, that is, perpendicular to the first direction.

The first pointed portion 231 protruded in the first direction and the second pointed portion 232 protruded in the second direction are configured for corona discharge to break the insulating property of a part of the air having insulating properties, It is preferable that the end portion is formed in a sharp shape so as to form a strong electric field in an instantly narrow region.

In addition, as shown in FIG. 2, the present invention is characterized in that a plurality of the twisted bodies 23 are spaced apart from each other at a predetermined interval. In the conventional art, in order to discharge corona over a wide range, (Pointed end) were arranged adjacent to each other. However, this may cause discharge charges to overlap due to the angle of discharge of the charges emitted by the corona discharge, resulting in flame (or spark) spattering and fire. The present invention can prevent the accident caused by the spark while maintaining the efficiency of the corona discharge through the plurality of concave bodies 23 having the mutually spaced structure.

In particular, the second pointed end 232, which is parallel to the electrode bar 21, also prevents deposition of dust to be removed, so that the electric field of the corona discharge can be continuously maintained, thereby preventing a reduction in dust collection efficiency.

Next, in FIG. 3, the procedure of the pointed body 23, particularly the first pointed end 231, is shown. 3, the splitter 23 is attached in contact with the outer surface of the electrode rod 21 and has a body portion 23 integrally formed with the first and second tip portions 231 and 232, (233). The folding line f may be provided at a boundary between the first leading end 231 and the body 233 so that the first leading end 231 is perpendicular to the body 233.

In addition, the effect of the first and second tip portions 231 and 232 produced in the above-described manner will be described in more detail with reference to FIG. 1, It can be confirmed that it moves from the lower side to the upper side. At this time, it is preferable that the dust is not adhered to the electrode rod 21 and the splitter 23 but is absorbed by the dust collecting member 30. However, due to the electrostatic phenomenon caused by the spark due to the discharge, (23).

In order to solve the problem, the present invention has a structure in which the first pointed end 231 is projected in the first direction and the second pointed end 232 is projected in the second direction, and the pointed body 23 is formed by Thomson processing Since it is provided in the form of a plate, the area obstructing the flow of air is minimized, and the dust sticking to the discharge member 20 can be minimized.

In addition, considering the flow direction of the washing water having the same direction as the flow direction of the air, the area obstructing the flow of the washing water is also minimized, so that the discharge member 20 is different It is possible to easily perform cleaning for elimination of the attached dust, and the dust collecting performance can be kept the same, thereby providing the discharge member 20 having excellent durability.

The length L232 of the first peak portion 231 is equal to the length L232 of the second peak portion 232. [

The first pointed end 231 is preferably symmetrically disposed at both ends of the body portion 233 for the 'wide range of corona discharge' And is symmetrically provided at both ends of the portion 233.

The present invention is characterized in that the length L231 of the first pointed end 231 is equal to the length L232 of the second pointed end 232. This is because the first pointed end 231, When the length L231 of the tip 231 is formed larger or smaller than the length of the second tip 232, the first tip 231 on each side of the electrode 21 is connected to the second tip 232 It is preferable to have the above-mentioned length characteristics in order to maintain the same degree of protrusion on each surface of the electrode bar 21, because it causes a difference in distance from the dust collecting member 30, Do.

On the other hand, Fig. 4 is a diagram showing a second embodiment of the sheath 23 of the present invention.

For convenience of explanation, the surfaces of the electrode bars 21 located in the respective directions (first to fourth directions) will be referred to as first to fourth surfaces.
