As such, since the structure supporting the edges of the emitter electrode unit 140 and the collector electrode unit 120 is made of a standardized divided assembly frame, it is easy and economical to adapt to the change of dimensions.

On the other hand, the emitter electrode portion 140 includes a connection member 145 having a plurality of rod electrodes 141 connected across the through portion. In this case, the rod electrodes 141 are spaced apart from each other by a predetermined interval, and each of the rod electrodes 141 is preferably made of a conductive material such as a metal such as stainless steel, a conductive polymer material, and the high voltage converter provided on the external power supply unit 200 side. It is preferable to be charged to the (-) electrode by applying a (-) power supply via. The rod electrode 141 is preferably made of a wire shape, but is not limited thereto, and may be provided in a hollow cylindrical shape or the like.

Since the rod electrode 141 is formed to be thin in a wire shape, when the external force is applied in the handling process after installation in a stretched state, the rod electrode 141 may increase due to plastic deformation. In order to solve this problem, in order to provide a cushioning effect even when an external force is applied, an elastic support means 142 such as a coiled spring is provided at the end of each rod electrode 141.

Is concentrated, and the charge is transferred to the edge of the hole 122 of the plate electrode 121. At this time, charged floats in the air are collected at the edge portion of the hole 122, and in this process, air flow is induced. That is, ion wind is induced as a flow of air passing through the hole 122 of the plate-shaped electrode 121 at the rod electrode 141 side. At the same time, the remaining suspended matter in the air that is diffused to an area other than the edge of the hole 122 may be charged to the positive polarity and collected again to the rod electrode 141.

In this process, most of the suspended matter in the air is collected on the surface of the plate electrode 121, the air is discharged to the rear through the hole. Here, in order to induce the flow of the ion wind to improve the dust collection performance, as shown in FIG. It is preferred to be arranged to face each other. In addition, in order to effectively collect the suspended matter, the rows of holes 122 formed in the plate-shaped electrode 121 are preferably staggered so as not to overlap each other with the holes in the rows adjacent to the left and right sides thereof.

In this case, the safety circuit unit is connected in parallel to the power interruption unit 218 and the power interruption unit 218 and the high voltage conversion unit 210 disposed between the high voltage converter 214 and the DC converter 202. Preferably, the detection unit 215, the amplifier 216, and the signal processor 217 are included.

In detail, the detection unit 215 includes a detection terminal for detecting an electrical signal of the high voltage converter 214, and the signal detected by the detection unit 215 is amplified by the amplification unit 216 to be a signal processing unit ( 217).

The signal processor 217 compares the amplified signal with a reference signal to determine whether it is an abnormal signal, and if it is determined to be an abnormal signal, generates a power cutoff signal and applies it to the power cutoff unit 218. The power cutoff unit 218 preferably includes a relay contact to cut off power in response to the power cutoff signal.

As such, when the voltage of the power supplied to the electrode parts 120 and 140 is determined to be an abnormal signal such as abnormal high pressure or abnormal low pressure, the power is not supplied to the emitter electrode part 140 and the collector electrode part 120. By doing so, it is possible to ensure stable operation of the float collecting device and to significantly improve safety.

As shown in FIG. 11, ion winds toward the plate-shaped electrode 121 are formed to face each other at the rod electrode 141 side of the pair of emitter electrode portions arranged to face each other. As air flows mainly along the surface of 121, the airborne matter is collected in the plate-shaped electrode 121. At this time, the collected air is discharged again to the outside through the flow flowing in the vertical direction around the point (P) where the electric field is concentrated, the air outlet is formed in the upper and lower portions of the support frame for this flow is preferred. .

In addition, since the flow flowing along the front and rear surfaces of the plate electrode 121 is formed, unlike the embodiment, the formation of holes 122 perforated in the plate electrode 121 may be omitted or reduced. As such, since both surfaces of the plate-shaped electrode 121 are used for dust collection, dust collection efficiency may be remarkably improved.
