ムラを生じるという問題点があった。A conventional electrostatic precipitating element uses a semi-insulating resin for reducing the amount of charge transfer for a high-voltage electrode constituting a collector portion, and prevents the generation of sparks between the electrodes. I have. However, due to its semi-insulating property, the surface potential of the high-voltage electrode decreases with increasing distance from the base point (the right end of the high-voltage electrode in FIG. 13) with the feed point as a base point.
The electric field strength decreases. For this reason, for example, at the left end of the high-voltage electrode shown in FIG. 13, the surface potential becomes the lowest, so that the electric field intensity decreases and the trapping performance decreases. Therefore, there is a problem that the collector performance of the entire collector unit is deteriorated or the collection unevenness occurs.

Will be described together. The electrostatic precipitating element according to the present embodiment includes an ionizing unit 3 and a collector unit 6 as in the conventional case, and a blower (not shown) is provided behind the collector unit 6. By driving, an air flow containing dust is generated in the direction of the arrow shown in FIG. 4 by the suction force. Also, a power supply (not shown) for the electric precipitator.

Positively charged. The positively charged dust (B in FIG. 4) moves toward the collector 6 and adheres to the negative (grounded) flat plate-shaped dust collecting electrode 4 due to the Coulomb force of the high voltage electrode 5. Due to such a conventional dust suction mechanism, the cleanliness of the air passing through the collector unit 6 is increased.

たりに通過する塵埃の量も最も多くなる。Here, FIG. 5 shows a surface potential distribution when a high voltage is applied to the high voltage electrode 5 via the power supply unit 9 and a wind velocity distribution diagram of the air passing through the high voltage electrode 5. Since the high-voltage electrode 5 is formed of a semi-insulating resin, the surface potential decreases as the distance from the power supply unit 9 that directly supplies a DC voltage decreases due to the semi-insulating property. Therefore, when the power supply portion 9 is provided at the center of the high voltage electrode 5, as shown in FIG. It becomes a surface potential distribution. As for the wind speed, the wind speed is generally the highest in the central portion where the influence of the pressure loss due to the outer frame member 12 is least, and the amount of dust passing per unit time is also the largest.

でき、全体としての捕集効率を上げることができる。In the relationship between the collection efficiency, the surface potential and the wind speed, the collection efficiency is low in a place where the surface potential is low and the electric field strength is also weak, and the dust passing through the unit where the wind speed is high per unit time is also used. The higher the volume, the lower the collection efficiency. Therefore, in the present embodiment, the surface potential of the portion where the wind speed is high and the amount of dust passing per unit time is large is the highest, and the surface potential distribution of the high-voltage electrode 5 substantially matches the wind speed distribution as a whole. In addition, dust collection unevenness can be eliminated, and the overall collection efficiency can be increased.

る。This is a dust collecting element having the above-mentioned structure, and the distribution of the magnitude of the electric field intensity on the high-voltage electrode surface is substantially matched to the wind speed distribution, so that the collection performance can be maintained almost uniformly. Thus, it is possible to provide a dust collecting element free from dust collecting unevenness. Further, since the high-voltage electrode 5 is formed of a semi-insulating resin, even if the conductive particles are contained in the dust flowing from the ionization unit 3 to the collector unit 6,
It is possible to prevent sparks between the electrodes of the collector unit 6 and from the vicinity of the power supply unit 9, thereby suppressing generation of unpleasant sound or light.

給電部９から遠ざかるに従って表面電位が低下する。The basic operation of the electrostatic precipitating element according to the second embodiment configured as described above is the same as that described in the first embodiment, and a description thereof will be omitted. Here, FIG. 9 shows a surface potential distribution when a high voltage is applied to the high voltage electrode 5 via the power supply unit 9. In FIG. 9, the surface potential distribution of the plate-like high voltage electrode 5 is shown in the vertical direction and the horizontal direction of the plate. Since the high-voltage electrode 5 is formed of a semi-insulating resin, the surface potential decreases as the distance from the power supply unit 9 increases as in the first embodiment due to the semi-insulating property.

The surface potential decreases toward the end, forming a mountain-like surface potential distribution. Also, since the wind speed distribution is the same as that described in the first embodiment, the wind speed is high and the surface potential of a portion where the amount of dust passing per unit time is large can be increased, and the surface potential distribution of the high voltage electrode 5 and the wind speed can be increased. Since the distribution substantially matches, the dust collection unevenness can be eliminated, and the dust collection efficiency as a whole can be increased.
