Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

Fig. 1 shows a schematic structural diagram of the application of the cathode wire to a wet electric dust collector, which has a honeycomb anode tube 40 as shown in the figure, and a cathode wire is disposed in each honeycomb hole of the anode tube 40. The anode tube 40 is connected to the ground. The upper end and the lower end of the cathode wire are respectively conducted with the negative pole of the constant current power supply.

The specific structure of the cathode wire for the wet electric dust collector is shown in figures 2-5. As before, the utility model provides a negative pole line for wet-type electrostatic precipitator can be used to set up in wet-type electrostatic precipitator's anode tube, wherein, the negative pole line includes rectangular form sheet 10, and the length direction's of sheet 10 both sides edge is formed with the coplanar first prickle 11 and the second prickle 12 that are located sheet 10, and the middle part of sheet 10 is formed with opening 20, and opening 20's edge is formed with the planar third prickle 21 and the fourth prickle 22 of perpendicular to sheet 10. The wafer 10 may be made of a corrosion-resistant metallic conductive material, such as a titanium alloy. Those skilled in the art will appreciate that the designations of the first barbs 11, the second barbs 12, the third barbs 21 and the fourth barbs 22 are only for the convenience of distinguishing from each other, and the actual understanding should not be limited to the positions specifically shown in the drawings.

The cathode wire of the application adopts an integrated sheet-shaped body structure, and the sheet-shaped body does not need to be bent. Relatively speaking, the body of prior art's negative pole line has taken place to buckle, leads to its structure to turn more to certain direction, and the negative pole line of this application need not be with under the condition of body bending, just can all form the prickle structure in four directions of mutually perpendicular, and the symmetry is better, can obtain better discharge and dust removal effect.

The first barbs 11 and the second barbs 12 are located on the same plane of the sheet-shaped body 10, and thus can be formed by punching or cutting off redundant parts at one time in other ways. The third prickle 21 and the fourth prickle 22 are perpendicular to the plane of the sheet-like body 10, so that the redundant parts can be cut off firstly during processing, and then the third prickle 21 and the fourth prickle 22 are respectively bent and formed. In the illustrated embodiment, the third and fourth barbs 21, 22 are of continuously formed triangular configuration, so that after the cut and fold, a large opening 20 is formed in the middle of the sheet 10, as shown. If the third and fourth barbs 21, 22 are not continuous structures (not shown), a plurality of discrete openings 20 are formed in the middle of the sheet 10 after the cut and fold. Further, if the third and fourth barbs 21 and 22 have a rectangular structure, the corresponding barb structure can be punched and bent at one time by means of stamping, and the opening 20 can be formed at the same time. From the above description, those skilled in the art will appreciate that the barbed structure of the present application is not limited to the triangular shape illustrated, but may also be rectangular or other structural forms.

In a preferred embodiment, the third barbs 21 and the fourth barbs 22 are oppositely oriented, so that the structure formed by the method has the best symmetry, and better dust removal effect is obtained. Of course, since the third barbs 21 and the fourth barbs 22 are oriented in opposite directions, it may be necessary to flip the sheet-like body 10 for punching twice when processing to form the barbed structure.

Further, the sheet-like body 10 may also be twisted into a spiral shape along its length (not shown in the figures), and such a spiral structure may further solve the problem of asymmetry of the discharge structure, similar to the prior art.

In another embodiment, the third and fourth barbs 21, 22 protrude above the plane of the sheet 10 by a height substantially equal to the distance of the first and second barbs 11, 12 relative to the longitudinal centerline of the sheet 10. Therefore, four groups of thorns which are vertically distributed mutually can be enabled to be approximately equal in height protruding outwards from the longitudinal center line, and the discharge effect which is approximately equal in four directions can be further obtained.
