Description of the Related Art In a casing of an electric precipitator, a plurality of electrode plates in which a dust collecting electrode plate and a discharge electrode are combined are suspended at a predetermined interval from a steel frame in an upper portion of the casing. In the case of (1), the size of the electrode plate is several meters in horizontal length and several tens of meters in vertical length. Then, when the electrode plate is deteriorated by the long-time operation of the electric precipitator, it is necessary to update the electrode plate with a new one.

Is usually done. In addition, as another renewal method, in addition to the ceiling opening of the casing of the electrostatic precipitator, the lower end of the hopper at the bottom of the casing is temporarily opened, and the electrode plate suspended by the crane is lifted or suspended inside the casing. Then, there is a method of carrying out and carrying in the electrode plate from the opening at the lower end of the hopper.

でないと作業ができない欠点がある。However, the method of updating an electrode plate for an electrostatic precipitator, which carries out and carries in the electrode plate from the ceiling opening of the casing, is susceptible to the wind, and the electrode plate fluctuates due to the wind. There is a risk that the electrode plate may be damaged by colliding with the like, and there is also a problem in terms of safety such that the electrode plate shaken by the wind collides with a worker. For this reason, there is a drawback that this method cannot be performed unless the wind speed is almost non-wind, such as 2-3 m / sec.

On the other hand, the renewal method of the electrode plate for the electrostatic precipitator, which carries out and carries in the electrode plate from the opening at the lower end of the hopper, has the advantage of being less affected by wind, but ash processing equipment such as a screw conveyor provided in the hopper, The inspection corridor and equipment such as electrical equipment must be temporarily removed and restored after the renewal work. For this reason, in addition to the removal and installation of the ceiling, it takes a long time to remove and return the equipment, so that there is a drawback that the renewal work period is longer. That is, this method has an advantage in the case of newly installing an electric precipitator, but it is difficult to adopt it as a renewal method.

The lower end of the electrode plate 14 when lifting it up
4 was slidably supported. This allows
Since the electrode plate 14 can be prevented from swaying due to the wind during the lifting work of the electrode plate 14, the electrode plate 14 can be prevented from colliding with an obstacle such as the casing 12 and damaged, and
Since the danger that the electrode plate 14 shaken by the wind collides with the worker can be avoided, the safety of the work can be improved. Therefore,
Update work can be performed as long as the wind is not too strong.
