Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dry electrostatic precipitator.

In this type of device, if the dust collected by suction accumulates on the dust collecting plate, the dust collection capacity of the dust collecting plate will decrease, so hammering is performed.For this reason, conventional devices use hammering as shown below. The parts were made up.

In FIG. 1, a pair of plate-shaped hammering beams 10
The longitudinal ends of A and 10B are fixed with bolts and nuts via hammer rods 14. Further, between the hammering beams 10A and 10B, each end of a plurality of dust collecting plates 12 each having a substantially L-shaped cross section on both sides is inserted via two pairs of spacers 16A and 16B. It is fixed to the beams 10A and 10B with bolts and nuts. Furthermore, as a recent trend, the flat plates of dust collection plates tend to become larger.
Since the rigidity of the flat plate is low, both edges are bent into a substantially L-shape as shown in FIG. In this manner, in the apparatus shown in FIG. 1, the dust collecting plate 12 is sandwiched and fixed between the hammering beams 10A and 10B via the spacers 16A and 16B.

Note that the spacers 16A and 16B are as follows:
Two cylindrical ones as shown in Figure 2, or two with end faces inclined outward or inward from the outer peripheral surface to the inner peripheral surface as shown in Figures 3 and 4. One cylindrical spacer 16A, one cylindrical spacer 16B is used as a pair.

As described above, in this type of device, the hammering beam 10A,
10B is fixed, so when hammering is performed and hammering force is applied to the hammering beams 10A and 10B, the hammering vibration is transmitted to the dust collection plate 12, and the vibration causes the dust collection plate 12 to Adhering dust will peel off.

However, in the conventional device, even when the hammering is performed, slipping occurs between the spacer and the hammering beam, so the hammering force transmitted to the dust collecting plate 12 is insufficient, and the dust attached to the dust collecting plate 12 is removed. Not peeled off enough,
Therefore, there is a problem in that dust remains on the dust collecting plate 12, and therefore the dust collecting plate 12 cannot effectively exhibit its dust collecting performance.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a dry electrostatic precipitator that can sufficiently remove dust attached to a dust collecting plate by hammering. It is in.

In order to achieve the above object, the present invention is characterized in that the spacer is formed integrally with the hammering beam.

Hereinafter, preferred embodiments of the apparatus according to the present invention will be described based on the drawings.

FIG. 5A shows a device according to the invention, and FIG. 5B shows a part of its top surface.

As mentioned above, in the present invention, the hammer beams 10A, 1
0B and spacers 16A, 16B are integrally formed. The reason why the hammering beams 10A, 10B and the spacers 16A, 16B are integrally formed in this way is that
In the conventional device, both were separate bodies, and it was confirmed through experiments that vibration slippage occurred between the two during hammering, and the hammering vibrations of the hammering beams 10A and 10B were not sufficiently transmitted to the dust collection plate 12. and
In the device according to the present invention, since both are integrated, there is no vibrational slippage between them.

In this embodiment, spacers 16A and 16B are formed by extruding hammered beams 10A and 10B, respectively. Note that these spacers 16A, 16B
are those shown in Figure 2, or Figures 3 and 4.
The hammer beam 10A as a pair shown in the figure,
The two may be integrated by welding to 10B.

As described above, the fixing holes formed in the bottom surfaces of the spacers 16A, 16B formed integrally with the hammering beams 10A, 10B and the mounting holes formed in the dust collection plate 12 are positioned, and the bolts 18 are inserted into these holes. The dust collecting plate 12 and the spacers 16A, 16B are fixed by the nut 20 inserted therethrough. Note that a hammering rod 14 is connected between the ends of the hammering beams 10A, 10B with two sets of bolts 22A, 22B and nuts 24A, 2.
It is attached at 4B.

The embodiment device shown in FIG.
Since the spacers B are integrally formed, when hammering is performed and hammering vibration occurs in the hammering beams 10A and 10B, the spacers 16A and 16B vibrate as one, and the vibration is reliably transmitted to the dust collecting plate 12. be done.

In this way, the hammering vibrations that were reliably transmitted from the hammering beams 10A and 10B to the dust collecting plate 12 without any loss provided sufficient vibration acceleration to the dust collecting plate 12, and the dust was deposited on the dust collecting plate 12. The dust is peeled off from the dust collection plate 12 by sufficient vibration acceleration, and the dust is effectively removed.

FIG. 6 shows the vibration characteristics 100 of the dust collecting plate 12 in the conventional device using the spacer 16 shown in FIG. 2, and the vibration characteristics 100 of the dust collecting plate 12 in the conventional device using the spacer 16 shown in FIGS. A vibration characteristic 102 and a vibration characteristic 104 of the dust collecting plate 12 in the device of this embodiment are shown. In the figure, the horizontal axis represents the vibration acceleration of the dust collecting plate 12, and the vertical axis represents the hammering beam 10 and the collecting plate. It represents the distance to the dust plate 12.

As can be understood from the above FIG.
It is possible to effectively remove and collect dust attached to the surface.

As explained above, according to the present invention, since the hammering beam and the spacer are integrally formed and both vibrate together, the hammering vibration of the hammering beam can be reliably transmitted to the dust collection plate without loss. Therefore, the dust collecting plate can be vibrated with a large acceleration, and therefore even highly adhesive dust adhering to the dust collecting plate can be effectively removed. As a result, according to the present invention,
Dust adhering to the dust collecting plate can be effectively removed by hammering, and therefore the dust suction force of the dust collecting plate can be maintained at a high level at all times.
