Description

[Detailed Description of the Invention] The present invention relates to an electrostatic precipitator, and more particularly to a moving electrode type electrostatic precipitator in which a collecting electrode plate moves and rotates.

A conventional moving electrode electrostatic precipitator has a configuration as shown in FIG.

That is, the dust collection electrode plate 40I/'i drive sprocket 1
It is suspended on a link chain 30 which is suspended at 0.

This link chain 30 is tensioned by its own weight and the weight of the dust collecting electrode plate and the driven wheel 20.

A discharge frame 50 is provided between the dust collecting electrode plates 40.

Further, a brush 60 is provided to sandwich the dust collecting electrode plate 40 and brush off dust attached to the dust collecting electrode plate 40.

Generally, guides 10 are provided on both sides of the dust collecting electrode plate 40 to prevent the dust collecting electrode plate 40 from rolling.

This guide TO has a configuration as shown in FIG.

That is, the guide TO is configured to sandwich and guide the upper end reinforcing frame 41 and the lower end reinforcing frame 42 that support the dust collecting electrode plate 40.

This guide TO is appropriately supported by a support member 11.

Further, the dust collecting electrode plate 40 is attached to the link chain 30 by an attachment member 43.

Since it is configured in this way, by driving the drive sprocket 10, the link chain 30 suspended on the drive sprocket 10 is moved, and the dust collection electrode plate 40 attached to the link chain 30 is oriented in one direction. Move to.

While the dust collection electrode plate 40 is moving, corona discharge is performed from the discharge frame 50 to collect dust in the gas.

However, in such a conventional moving electrode type electrostatic precipitator, the guide 70 is a ground electrode like the dust collecting electrode plate 40, and the guide 70 remains stationary even though the dust is electrostatically collected. Therefore, if the collected dust is not peeled off and the electrostatic precipitator is operated for a long time, the charged state of the electrostatic precipitator deteriorates, and the dust collection performance deteriorates.

In addition, in the conventional moving electrode type electrostatic precipitator, the upper end reinforcing frame 41 and the lower end reinforcing frame 42 of the dust collecting electrode plate 40 move while continuously contacting the guide 70, which causes damage due to wear. It had

An object of the present invention is to provide a moving electrode electrostatic precipitator that does not reduce dust collection performance.

In the present invention, the conventional guide is removed and longer ones are used for the upper end reinforcing frame and the lower end reinforcing frame of the dust collecting electrode plate 40.

By attaching the upper and lower end reinforcing frames to the link chain, it is possible to prevent the dust collection electrode plate from lateral shaking and to prevent deterioration in dust collection performance.

Examples of the present invention will be described below.

FIG. 3 shows an embodiment of the present invention.

In the figure, an upper end reinforcing frame 411 is added to the dust collection electrode plate 40.

This upper end reinforcing frame 411 projects long toward the link chain 30 and is provided in contact with the link chain 30.

Further, a lower end reinforcing frame 421 is attached to the lower end of the dust collection electrode plate 40.

This lower end reinforcing frame 421 projects long toward the link chain 30 and is provided so as to be in contact with the link chain 30.

In this way, the upper end reinforcing frame 411 and the lower end reinforcing frame 421
Both have a length exceeding the link chain 30, and the portion of the reinforcing frame beyond the link chain is located on either the left or right side of the link chain 30.

Whether it is located on the left or right side of the link chain 30 is determined by the direction of rotation of the sprocket of the dust collection electrode plate 40.

That is, if the rotation is in the direction of the arrow in FIG. 4, it will be on the right side of the link chain 30.

If it rotates in the opposite direction, it is configured to be located on the left side.

Therefore, according to this embodiment, if the upper end reinforcing frame 411 tries to move away from the link chain 30, the lower end reinforcing frame 421 that has contacted the tensed link chain 30 will impede the movement, and in the opposite case, the upper end reinforcing frame As a result of the interference caused by 411, the electrode plate 40 can move stably like a tensioned link chain 30.

As explained above, according to the present invention, deterioration in dust collection performance can be prevented.
