Specifically, the barbed sheets 2 and the conductive rod 1 may be rigidly connected (e.g., welded) directly, but the barbed sheets 2 cannot be adjusted in position or angle relative to the conductive rod 1, so that the barbed sheets 2 and the conductive rod 1 are contacted and conducted in a manner of being attached, and one barbed sheet 2 is attached to each of two opposite sides of the same position of the conductive rod 1, at this time, the two corresponding barbed sheets 2 may be symmetrical relative to a middle plane thereof, that is, the two barbed portions 201 face the same direction, so as to enhance a corona effect, or be centrally symmetrical relative to an axis of the conductive rod 1, that is, the two barbed portions 201 face opposite directions, so as to enhance a corona range.

As shown in fig. 2 and 4, the first and

second bur sheets

4 and 5 are centrosymmetric around the axis of the collector bar 1.

Specifically, first prickle piece 4 and second prickle piece 5 here are central symmetry, and then two prickle portion 201 is towards opposite direction, has realized the bipolar corona of a prickle 203 line promptly, can effectively enlarge the corona scope, reduces the size of the anode plate that needs, and not only save material, the electrostatic precipitation effect is stronger moreover.
