Description

Description: TECHNICAL FIELD The present invention relates to an ionization device arranged in an electrostatic precipitator.

(Prior Art) Generally, in an electrostatic precipitator, an electric precipitator is provided inside a main body casing, and an ionizer having an ionization wire is provided on an inlet side of polluted air to the precipitator. ,
After contaminated air is ionized by this ionization device, the contaminated air is supplied to the dust collecting portion, the dust in the contaminated air is removed by the dust collecting portion, and the purified air is supplied to the indoor side.

However, since dust adheres to the ionization wire of the above-described ionization device as it is used, and the discharge effect of each ionization wire is impaired, it is necessary to remove the adhered dust.

Thus, as a means for removing dust attached to the ionization line, conventionally, for example, as shown in FIG. 10 of JP-A-64-15162 and as shown in FIG. 10, two ionization lines (W) ( W) are arranged parallel to each other in the vertical direction, have fitting grooves (a) (a) that can be fitted into the respective ionizing wires (W) on both sides in the lengthwise direction, and have hooks ( When a dust removing jig (J) is formed by connecting a rope (R) via F), and the dust (D) adheres to each of the ionization wires (W), the jig (J) is removed. Set between the ionization wires (W) with the fitting grooves (a) fitted in the ionization wires (W), loosen the rope (R), and load the jig (J) with its own weight. By lowering the ionization wires (W) in the fitting grooves (a).
The adhered dust (D) is scraped off.

(Problems to be Solved by the Invention) In the dust removing means as described above, the jig (J) is lowered by its own weight, and the jig (J) is inserted in each of the fitting grooves (a). Since the attached dust (D) of each ionization line (W) is removed, the above-mentioned each ionization line (W) is removed.
It is necessary to extend the above in the vertical direction, which limits the internal arrangement configuration of the electrostatic precipitator, and conversely, the jig (J) can only be used for a specific electrostatic precipitator, and its applicable model is However, since the jig (J) needs to be attached and detached near the respective ionization wires (W), there is a risk of causing danger. The present invention has been made in view of the above problems, and its purpose is to limit the internal arrangement configuration of the electrostatic precipitator, and also be applicable to all models without limiting the applicable models, Moreover, it is another object of the present invention to provide an ionization device for an electrostatic precipitator that can easily and safely perform dust removal work on an ionization wire.
