Description
Technical field
This utility model relates to the field of Environment Protection of flue gas deep purifying, in particulars relate to a kind of wet electrical dust precipitator new and effective, simple in construction, the easily fabricated and Flexible cathodes line of installation.
Background technology
Polar curve is that electric cleaner produces air ionization electric discharge in high voltage electric field, forms the component of uneven high pressure field intensity, is one of core parts.Therefore, version and the installation quality of cathode line directly affects efficiency of dust collection.
Polar curve does not require nothing more than discharge performance good (such as having higher secondary current and voltage parameter), and has enough intensity and reliable installation form.The polar curve of two kinds of forms commonly used by current wet electric cleaner, one is lead-antimony alloy polar curve, this polar curve limits due to material characteristic, discharge tip can not be the sharpest keen, relative discharge ability is more weak, in addition lead antimony Material Strength is poor, and polar curve affects the properly functioning of electric cleaner after rupturing, and has dissolving lead with wet except collecting liquid discharge formation secondary pollution in acidic flue gas.Another kind isφThe tubular rigid line of 10～15mm steel tube surface welding spray points, polar curve length is generally more than 5 meters, and slender rod piece is easily bent deformation, changes original design die opening, reduces efficiency of dust collection, and cost is of a relatively high.
Summary of the invention
The problem that this utility model exists for existing polar curve, it is provided that a kind of wet cottrell flexibility polar curve, flexibility polar curve discharge inception voltage is low, field intensity is high, linearity good and is difficult to the fine solid particle that bonds for this.
The purpose of this utility model solves by the following technical programs:
A kind of flexible polar curve of wet scrubber, including cathode line body, described cathode line body is formed through distortion by ribbon motherboard, body helically list structure after distortion, the region of discharge outer surface of cathode line body is provided with many group sawtooth discharge tip along the hand of spiral, and often group sawtooth discharge tip is bidentate structure.
Further design of the present utility model is:
The region of discharge outer surface of cathode line body is uniformly provided with many group sawtooth discharge tip along hand of spiral clearance-type, and often the bidentate structure of group sawtooth discharge tip is M type.The characteristic of polar curve electric discharge can adjust by adjusting the overall dimensions of bidentate.
In the bidentate structure of sawtooth discharge tip, in bidentate, two space widths are 20～40mm, the wedge angle angle of discharge tip be 30 °～
60 °, tooth depth 8～12mm.

Described cathode line body and sawtooth discharge tip use titanium alloy material to make.
Described ribbon motherboard width 30mm, thickness is 0.8～1.2mm.
The upper/lower terminal of described cathode line body respectively sets two groups of bolts hole.
This utility model has the following advantages compared to existing technology:
1, this utility model design a kind of new and effective, simple in construction, easily fabricated and flexible polar curve for electrostatic precipitator of installation, its construction features can ensure that the operational efficiency of wet electrical dust precipitator.
2, this utility model polar curve discharge inception voltage is low, electric current per unit length is big, electric current is uniform, eliminate the electric discharge dead-time problem of existing polar curve, improves the efficiency of dust collection of wet electrical dust precipitator.
3, polar curve linearity of the present utility model is good, and die opening not fluctuation under the high flue gas flow rate operating mode of 3-5 meter per second, electric pulse field parameter is stable.
4, polar curve material surface of the present utility model is bright and clean, and glutinous fine solid particle the most easy to stick, during long-term operation, discharge effect is unattenuated.In addition periodically to polar curve surface washing, polar curve any surface finish is as newly helped to ensure that discharge effect does not reduces.

Detailed description of the invention
Embodiment one:
Described as shown in Figure 1, Figure 2, the flexible polar curve of wet scrubber of the present utility model, including the cathode line body 1 being made up of titanium alloy material, cathode line body 1 is formed through distortion by ribbon motherboard, body helically list structure after distortion.The region of discharge outer surface of cathode line body 1 is provided with many group sawtooth discharge tip along hand of spiral clearance-type, and often group sawtooth discharge tip uses bidentate structure, bidentate design to help to create more electronics, contribute to dust and droplets.Spacing (helical pitch of distortion about 600-800mm) between two adjacent groups sawtooth discharge tip is 30～80mm.The upper/lower terminal of cathode line body respectively sets hole, a location.Add man-hour, numerical control press is first used to go out many group sawtooth discharge tip at cathode line body 1 region of discharge outer surface along straight line, again the ribbon motherboard of region of discharge being reversed into strip-spiral structure, after processing, sawtooth discharge tip is just along the hand of spiral arrangement after torsion.
When polar curve is installed, upper end bolt holes is embraced in standard trolley 3, locks by bolt passing through bolt hole, and lower end is used for connecting weight 4.Also being tightened by bolts behind weight hanging hole polar curve twists into spiral type posterior end bolt hole, the cervical region of weight is stuck in the preformed hole of positioning framework, so ensures the problem that polar curve occurs without swing in high velocity smoke.
This example can be used in TA2 titanium alloy material, has excellent decay resistance, and polar curve is not easy to fracture, and service life is long, is suitable for wet electrical dust precipitator and uses.
