Abstract

PURPOSE:To simply perform the mounting of an ionization wire under tension, by hooking clamp metal fittings attached to both ends of the ionization wire with comb shaped conductive leaf springs. CONSTITUTION:Two cylindrical insulators 15 are externally fitted to an ionization wire 11 and clamp metal fittings 18 are secured to both ends of said ionization wire 11. Next, when the clamp metal fittings 18 are hooked with the cut groove parts of comb shaped conductive leaf springs 17, each ionization wire 11 is attached under constant tension by the repulsive force of the conductive leaf springs 17. By this method, the mounting of the ionization wire can be performed simply under tension and the reduction in the number of processes and cost is attained.

Description

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

The structure of a conventional example and its problems FIG. 1 shows a two-stage electrostatic precipitator comprising an ionization section having an ionization line 1 and a counter electrode 2, and a dust collection section having a dust collection electrode 3 and an accelerating electrode 4. By providing ventilation to the ionization section and the dust collection section, the passing dust is charged in the ionization section, and the charged passing dust is collected in the downstream dust collection section by an electric field.

A specific conventional structure will be explained using FIGS. 2, 3, and 4. 1 to 4 are the same as in Figure 1, 6 is a cylindrical insulator passed through the ionization wire 1, 6 is the body, 7 is a winding that applies tension to the ionization wire 1, and 8 is a winding formed on the body 6. The hook of the ionized wire 1 and the coiled spring 7 is a portion.

Conventionally, the ionization wire 1 of the two-stage electrostatic precipitator was attached by forming a ring at both ends of the ionization wire 10, with one end pulled directly and the other end pulled through a coiled spring 7, as shown in FIG. It was common for the hooks to be attached to each part 8 one by one.

However, with this configuration, it is necessary to form rings at both ends of each ionized wire 1 and to attach the coiled spring 7 to one end, which takes time and effort to assemble, leading to an increase in man-hours and cost. In addition, when forming rings at both ends of the ionized wire 1, touching the ionized wire 1 or applying force to it will affect its surface condition, resulting in deterioration and unstable discharge. there were.

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 the ionization wire of the ionization section is stretched by hooking a comb-shaped conductive leaf spring to a comb-shaped conductive plate spring with a tying fitting fixed to both ends.

The comb-shaped conductive leaf springs were fixed by forming lips on the body to create grooves, into which the leaf springs were fitted.

Therefore, when attaching the ionization line to the ionization section, the conventional labor and effort can be saved and the number of times the ionization must be touched can be reduced.

Here, each ionized wire 11 is attached under a constant tension due to the repulsive force of the conductive leaf spring 17.

Effects of the Invention As is clear from the above embodiments, the present invention allows the ionized wire to be easily stretched by hooking the stoppers attached to both ends of the ionized wire to the comb-shaped conductive leaf springs, which is different from the conventional method. Compared to this, it saves time and effort, improves work efficiency, and reduces man-hours and costs. In addition, when the ionized wire is installed, the number of times of force applied to the ionized wire is reduced, so the surface condition is less affected, enabling stable discharge and improving reliability. be.
