Also occurred at present a kind of in the middle of the demist section be the cathode line of dentalation, but tooth is to be provided with at interval, tooth pitch is very big, tooth is discontinuous, and the end of tooth is pointed, under same voltage, point of discharge is few, and easily produces bigger electric current and damage cathode line.Need a kind of moderate cost and the cathode line of better performances satisfies production requirement.The utility model is exactly should this requirement and a kind of novel cathode line is provided.
The utility model content
The utility model provides that a kind of point of discharge is many, price is low, the wet electrostatic demister cathode line of good corrosion resistance, has solved that the cathode line point of discharge that present wet electrostatic demister equipment uses is few, fragile, the problem of demist weak effect.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of wet electrostatic demister cathode line, comprise canned paragraph, middle demist section and following canned paragraph, described centre of going up canned paragraph, middle demist section and following canned paragraph is keel, described keel center is surrounded by steel wire, described both sides of going up canned paragraph and following canned paragraph are the fin shape, the demist section left and right sides is the tooth row shape in the middle of described, and described tooth row is continuously arranged stepped tooth, and these stepped tooths become effective point of discharge.
As further improvement of the utility model, in order to increase the life-span of cathode line, in technique scheme, described each relative left tooth and the mutual setting straggly of right tooth.
In technique scheme, described scope straggly mutually is 5～15mm.
In technique scheme, described middle demist section both sides are provided with 98～102 stepped tooths for every meter.
In technique scheme, the transverse tooth thickness of described stepped tooth is 1.5～2.5mm.
In technique scheme, described keel, fin and tooth row are lead-antimony alloy.
In technique scheme, the cross section of described keel is ellipticity.
In technique scheme, be convenient installation cathode line, the described fin of going up the canned paragraph both sides is interrupted setting, and discontinuities is divided the formation breach, so that adopt the mode of binding to fix.
Compared with prior art, advantage of the present utility model and good effect are:
The utility model wet electrostatic demister cathode line, by adopting the middle demist segment structure of tooth row shape, about all be continuously arranged stepped tooth, this structure point of discharge is many, the efficient height, discharge inception voltage is low, and it adopts the lead-antimony alloy manufacturing, price is low, corrosion resistance and good, demist is effective, installs simple, life-span is long, can be widely used in various electrostatic precipitators.
Description of drawings
Fig. 1 is the structural representation of described the utility model wet electrostatic demister with cathode line;
Fig. 2 is the vertical view of Fig. 1;
Wherein: 1, go up canned paragraph; 2, middle demist section; 2-1, stepped tooth; 3, following canned paragraph; 4, steel wire; 5, fin; 5-1, breach; 6, keel; The center of h, left tooth that each is relative and right tooth is distance straggly mutually.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model wet electrostatic demister cathode line, by adopting middle the demist segment structure of tooth row shape, about be continuously arranged stepped tooth all, obtained well except that fog effect, adopt the lead-antimony alloy manufacturing simultaneously, reduced cost.
Embodiment one, a kind of wet electrostatic demister cathode line, this cathode line comprises canned paragraph 1, middle demist section 2 and following canned paragraph 3, it is 2 millimeters steel wire 4 that its center keel 6 are surrounded by diameter, and both sides are fin 5, and total length is 6 meters, width is 50 millimeters, wherein going up canned paragraph is 1.5 meters, and middle demist section is 4 meters, and following canned paragraph is 0.5 meter.
In order to increase the life-span of cathode line, in technique scheme, the center of described each relative left tooth and right tooth is straggly mutually, and its mutual distance h straggly is 10 millimeters, and cathode line just is difficult for being fractureed like this.
The cross section of described keel 6 is ellipticity (seeing accompanying drawing 2), and its major axis is 10 millimeters, and minor axis is 8 millimeters.
Described keel 6, fin 5 and stepped tooth 2-1 are lead-antimony alloy.
Be the convenient cathode line of installing, the both sides fin 5 of canned paragraph 1 is interrupted and is provided with on described, and it is interrupted part and forms breach 5-1, adopts the mode of binding to fix so that pass U bolt.
