Abstract:
1. An improvement on an electrostatic precipitator, comprising a frame including top and bottom board parts, and vertical rod part securely joined to the top and the bottom board parts; a plurality of first kind of metallic boards equidistantly spaced apart between the top and the bottom board parts of the frame; the first kind of metallic boards having a plurality of big through holes, and a plurality of small through holes thereon; second kind of metallic boards equidistantly spaced apart between the top and the bottom board parts of the frame, and each positioned between two adjacent ones of the first kind of metallic boards; the second kind of metallic boards having a plurality of big through holes, and a plurality of small through holes thereon; the big holes of the second kind of metallic boards being aligned with corresponding small holes of the first kind of metallic boards; the small holes of the second kind of metallic boards being aligned with corresponding big holes of the first kind of metallic boards; and a plurality of dividable supporting rods joined to both the top and the bottom board parts of the frame at two ends thereof, and passed through corresponding through holes of the metallic boards so as to support the metallic boards equidistantly spaced apart in position; and being characterized by: each dividable supporting rod being made of a plurality of connectable parts; each of the connectable parts being formed with an insertion end portion at one end, and a hollow holding end portion at other end thereof; each dividable supporting rod being assembled by means of tightly fitting insertion end portions of connectable parts to adjacent hollow holding end portions thereof; the insertion end portions being formed so as to be capable of being tightly passed through the small through holes of the metallic boards; the supporting rods being formed with such a size as to be apart from edges of corresponding big through holes of the metallic boards; thus, the metallic boards being spaced apart and firmly held in position by means of tops of hollow holding end portions of those connectable parts that are joined to small through holes thereof.
