いる。FIG. 1 is a view showing a current plate according to an embodiment of the present invention, in which (a) is a plan sectional view, and (b) is a schematic front sectional view. Current plate 71 of the embodiment of the present invention
Is composed of a hollow cylindrical frame 710, a spindle, and support plates 716, 717, 718, 719 connecting these. The frustum connects the first frusto-conical portion to the upper end of the cylindrical portion 714, and the second frusto-conical portion at the lower end, so that each of the conical portions tapers away from the cylindrical portion.
The connected spindles are arranged on a cylindrical frame so that the central axes thereof coincide with each other, and a support plate for joining the spindle and the frame is arranged in a plane passing through the central axis. The first frusto-conical portion has a top surface 712 and a side surface 713 and is welded without gaps, while the second frusto-conical portion has no top surface and is perforated, and has only a side surface 715. Become. Even if dew condensation occurs on the inner surface of the spindle or cooling water mixes in,
It is intended to fall out of a hole in the second frustoconical part.

Are in a plane passing through the common rotation axis of the frame and the spindle, and extend radially in the radial direction. Therefore, the planar section of the current plate has a high aperture ratio as shown in FIG.

For the first time, the development research of the present invention has revealed that by designing to be 40 m / s, exhaust gas can be rectified and dust can be prevented from being adhered to the rectifying plate.

渦流の発生によるダストの付着を防止するためである。As shown in FIG. 1C, the cross section AA of the supporting plates 716 to 719 is sharp near the upper end and the lower end so that the plate thickness is linearly reduced. The upper end is for reducing dust adhesion due to the collision of exhaust gas containing dust, and the lower end is for preventing dust adhesion due to turbulence or eddy current.

該範囲の比率が望ましいことを見出したものである。The ratio of the diameter of the hollow cylindrical portion 714 to the diameter of the frame 710 is preferably in the range of 0.35 to 0.65. The smaller this ratio is, the higher the aperture ratio of the current plate is, and the dust contained in the exhaust gas is less likely to adhere to the current plate and is less likely to be clogged. As a result of conducting a computer simulation test and an experiment using a test machine for various ratios, it has been found that a ratio in the range is desirable.

However, even when the current plate of the example was used, scattering of mist to the bag filter connected after the cooling tower was not observed at all.

The high part is formed, the exhaust gas hardly flows near the side wall of the main body, the dust contained in the exhaust gas does not adhere to the side wall, and the dust hardly adheres to the straightening plate,
The effect of not blocking even after a long operation is obtained.
