Description
Technical field:
The invention belongs to the chemical industry environmental protection technical field, relate to a kind of electrostatic precipitator parts, relate in particular to a kind of ring aciculiform electricity demist cathode line.
Background technology:
Electricity demist (dirt) device is to capture droplet or dust in the waste gas with the High-voltage electrostatic purification method, its operation principle is after dusty gas enters electric field equably, near corona discharge electrode, produce corona phenomenon, make gas ionization, there are a large amount of electronics and ion in the gas after the ionization, these electronics and ion and the droplet (dust) that enters electric field are combined into a band point particle, charged particle is gathered in anode and the negative electrode of electric demist (dirt) device under the effect of electric field, landing downwards under rapping and action of gravitation, discharge the purified gas atmosphere that enters up to standard by leakage fluid dram (ash exhauster).
With respect to other other gas cleaning plants, electricity demist (dirt) device has the advantages such as demist rate height, stable performance, pressure drop are little because of it, being used widely in industries such as non-ferrous metal metallurgy, sulfuric acid and titanium white production, is the capital equipment in the gas cleaning flow process.But owing to many-sided reason, still there are problems in present electric demist (dirt) device, the cathode line of especially electric demist (dirt) device.Cathode line is the vitals of electrostatic precipitator, cathode line in the market mainly contains the versions such as spirality cathode line, twist shape cathode line, shaft-like acupuncture cathode line, tubulose prickle shape cathode line, star-type cathode line, zigzag cathode line, its shortcoming is intensity difference, easy fracture, point of discharge is few, poor corrosion resistance, and cost is high, service life is short, and it is undesirable to remove fog effect.
The spirality cathode line have discharge evenly, high, applicable thin dust, the characteristics such as easy for installation of collecting of electric field breakdown voltage.But common spiral cathode line is in fact a kind of extension spring, and pitch is very little or be zero, it to be pulled into the very large state of pitch when mounted, plastic deformation occurs and ruptures in yield limit easily that exceed spring material, thereby causes the anode and cathode short circuit to force electric field to quit work.
The twist shape cathode line has the characteristics such as electric field breakdown voltage is high, discharge is even, easy for installation.But, common twist shape cathode line since linear tiny cause intensity, rigidity a little less than, have in actual use easily the problems such as broken string.
Shaft-like acupuncture cathode line is widely used owing to having the advantages such as fastness is good, moderate, strength of discharge is large.Its draw point circular prong or the flat pins of adopting, boring tight fit or the electric resistance weldings of adopting are fixed more between the round steel of draw point and shank more.Boring very useless man-hour, round pin and circular shank are to contact during electric welding, and contact-making surface is too little may to affect weld strength, will bear long-term rapping impact when cathode line move in electric cleaner, so the height of the welding requirements between acupuncture and the shank.
The advantage of tubulose prickle shape cathode line is that discharge inception voltage is low, and discharge is strong and current density is large.Shortcoming is that electric current distribution is inhomogeneous, and the prickle of this type of cathode line is to adopt on steel pipe the radially mode of welding, and the phenomenon that often comes off under electric cleaner long term high temperature and strong rapping has a strong impact on dust removing effects.
Star-type cathode line advantage is that electric current distribution is more even, and shortcoming is that discharge inception voltage is higher.
The zigzag cathode line is made by flat metal material usually, and its discharge body is bilateral symmetry or the sawtooth that is interspersed, and such cathode line point of discharge is less, and intensity is on the weak side.
Summary of the invention:
The objective of the invention is the shortcoming for the existence of cathode line prior art, the electric demist ring needle-shaped cathode line that a kind of point of discharge is many, discharge is even, intensity is high, corrosion-resistant, price is low is provided.
The present invention is achieved in that
A kind of ring aciculiform electricity demist cathode line, comprise cathode bar, terminals, nut, ring pin, it is characterized in that: cathode bar is the solid circles metal, and parallel distance arranges the ring pin on cathode bar, the terminals at cathode bar two are helicitic texture, the fastening nut of using of terminals configuration.
The above-described ring pin outside is annular cutting edge.
Above-described cathode bar rod length is 1～8m, diameter 4～12 mm of cathode bar.
The cutting edge of a knife or a sword height of above-described annular cutting edge is 2～5mm.
Above-described ring pin parallel distance is 20～50mm.
Above-described cathode bar material is that the materials such as stainless steel or lead are made.
This cathode line compared with prior art has the following advantages:
Therefore 1, the ring pin of this electric demist cathode line and cathode bar are connected as a single entity when processing and manufacturing, are not to weld up in the later stage, and be very firm, do not have long-term use and situation about coming off, and guaranteed the efficient operation of electrostatic precipitator.
2, this cathode line adopts ring aciculiform cutting edge discharging structure, and point of discharge is many, discharge is even, demist is effective.
3, the terminals of this cathode line adopt nut to be fixed on the cathode frame of demister, and are easy for installation.
4, this electric demist ring needle-shaped cathode line is to be processed by the solid circles metal integral, can select the materials such as stainless steel, lead to make according to the difference of processing gas medium, intensity is high, corrosion-resistant, can effectively solve the problem that cathode line often breaks in the electrostatic precipitator running.
5, this cathode line handling ease, long operational time, electric demist is effective, has preferably economic benefit, social benefit and ecological benefits.
