Description

[Detailed description of the invention] Industrial applications The present invention relates to an electrostatic precipitator.

Structure of the conventional example and its problems FIG. The electrostatic precipitator is shown, and by supplying ventilation to the ionization section and the dust collection section, the ventilation dust is charged in the ionization section, and the charged passing dust is collected in the downstream dust collection section by an electric field. Further details will be explained using FIGS. 2 and 3. 6 is a cylindrical insulator inserted into both ends of the ionized wire 10, 6 is a body, and 7 is a spring that applies tension to the ionized wire 1.

Conventionally, in the ionization section of the two-stage electrostatic precipitator,
A cylindrical insulator 5 is interposed between the ionized wire 1 and the body 6 to prevent creeping discharge, prevent vibration of the ionized wire 1, and reduce the discharge area.

However, when assembling the ionization section using the cylindrical insulator 6, two cylindrical insulators 5 are attached to one ionization wire 1.
There is a laborious work involved in attaching the parts 9 in advance and assembling them on the body 6, which leads to an increase in man-hours and costs. Furthermore, during assembly, touching the ionized wire 1 affects the surface condition of the ionized wire 1, causing unstable discharge, resulting in a lack of reliability.

OBJECTS OF THE INVENTION The present invention eliminates these drawbacks and provides a high quality and inexpensive electrostatic precipitator.

Structure of the Invention The electrostatic precipitator of the present invention includes an ionization section that charges passing dust, a dust collection section that is disposed downstream of the ionization section and that collects the dust charged in the ionization section, and the ionization section. and a ventilation means for providing ventilation to the dust collection section, and by providing an insulator integrated with the ionization wire support section around both ends of the ionization wire in the ionization section and around the ionization wire, the ionization wire This makes insulation easier by weakening the electric field around both ends.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In Figures 4 and 5, 11 is A
Ionization wire, 18 is a support portion of the ionization wire 11, +
1 19 is a spring that applies tension to the ionization wire 11, 12 is a counter electrode, 13 is a dust collecting electrode, 14 is an accelerating electrode, 16 is a body, and 15 is an insulator, which is integrated with the body 16. 17 is an elastic body. A fan or similar ventilation means is omitted.

To explain the operation in the above configuration, the ionization line 11
An insulator 15 is placed around both ends of the ionized wire 11 and around the ionized wire 11.
By providing this, the electric field becomes weak and corona discharge is prevented. Therefore, the dust charged by the ionization line 11 and the counter electrode 12 does not adhere to the portion where the dust collection electrode 13 and the acceleration electrode 14 are in contact with the body 16. For this reason, the insulation of the support portion of each electrode is maintained, and the service life is maintained for a long time.

In addition, in the ion draft type electrostatic precipitator, even greater effects can be obtained by inserting an insulating plate between both ends of the plurality of ionized wires 11 and the counter electrode 12.

The key is to weaken the electric field strength at the end of the ionized wire with an insulator, eliminate corona discharge at the end, reduce dust adhesion to the end insulator, and maintain good insulation.

Effects of the Invention As is clear from the above embodiments, the present invention provides an insulator that is integrated with the ionization wire supporting portion around both ends of the ionization wire and around the ionization wire, so that one ionization wire can be Compared to the conventional structure in which two cylindrical insulators are attached in advance and assembled to the body, it is possible to greatly improve workability, reduce the number of parts and reduce costs, and also reduces the number of times the ionization wire is touched during assembly. Therefore, the influence of the ionization line on the surface state is reduced, making it possible to perform stable discharge and improve reliability. Furthermore, by narrowing the discharge area, it is possible to avoid dust from adhering to the area where the electrode and the body come into contact, thereby improving safety and extending the service life.
