Description
technical field:
The invention belongs to technical field of environmental protection in chemical industry, relate to a kind of electrostatic precipitator parts, particularly relate to a kind of spiral needle electricity demist cathode line.
background technology:
Electricity demist (dirt) device comes droplet in trap exhaust or dust with High-voltage electrostatic purification method, its operation principle is after dusty gas enters electric field equably, corona phenomenon is produced near corona discharge electrode, make gas ionization, a large amount of electronics and ion is there is in gas after ionization, these electronics and ion and the droplet (dust) entering electric field are combined into is with some particles, charged particle is gathered in anode and the negative electrode of electric demist (dirt) device under the effect of electric field, landing downwards under the effect of rapping and gravity, discharged by leakage fluid dram (ash exhauster), purified gas is up to standard enters air.
Relative to other other gas cleaning plants, electricity demist (dirt) device because of its have that demist rate is high, the advantage such as stable performance, pressure drop are little, being used widely in industries such as non-ferrous metal metallurgy, sulfuric acid and titanium white production, is the capital equipment in gas cleaning flow process.But due to many-sided reason, still there are problems in current 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, except fog effect is undesirable.
Spirality cathode line have electric discharge evenly, electric field breakdown voltage is high, be suitable for and collect thin dust, the feature such as easy for installation.But normal spiral cathode line is in fact a kind of extension spring, pitch is very little or be zero, the very large state of pitch will be pulled into when mounted, exceed the yield limit of spring material, easily plastic deformation occur and rupture, cause anode and cathode short circuit thus force electric field to quit work.
Twist shape cathode line has that electric field breakdown voltage is high, the feature such as even, easy for installation of discharging.But, common twist shape cathode line due to linear tiny intensity, the rigidity of causing more weak, there is the easily problem such as broken string in actual use.
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 circular prong of the many employings of draw point or flat pin, between draw point and the round steel of shank, boring tight fit or the electric resistance welding of adopting is fixed more.Boring is given up man-hour very much, and during electric welding, round pin and circular shank are point cantact, and contact surface is too little may affect weld strength, and will bear long-term rapping when cathode line is run in electric cleaner and impact, the welding requirements therefore between acupuncture and shank is high.
The advantage of tubulose prickle shape cathode line is that discharge inception voltage is low, and electric discharge is strong and current density is large.Shortcoming is that electric current distribution is uneven, and the prickle of this type of cathode line is the mode adopting radial welding on steel pipe, and the phenomenon often come 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 relatively more even, and shortcoming is that discharge inception voltage is higher.
Zigzag cathode line is made up of flat metal material usually, the sawtooth that its discharge body is bilateral symmetry or is interspersed, and such cathode line point of discharge is less, and intensity is on the weak side.
summary of the invention:
The object of the invention is the shortcoming existed for cathode line prior art, the electrostatic precipitator helical discharge bodily form cathode line that a kind of point of discharge is many, electric discharge is even, intensity is high, corrosion-resistant, price is low is provided.
The present invention is achieved in that
A kind of spiral needle electricity demist cathode line, comprise cathode bar, terminals, nut, helical discharge body, it is characterized in that: cathode bar is solid circles metal, helical discharge body is set on cathode bar, the terminals at cathode bar two are helicitic texture, the fastening nut of terminals configuration.
Above-described cathode bar rod length is 1 ~ 8m, diameter 4 ~ 12 mm of cathode bar.
The outside of above-described helical discharge body is thread cutting edge, and the thread cutting edge of helical discharge body and the spacing of cathode bar are 2 ~ 5 millimeters.
The thread cutting edge spacing of above-described helical discharge body is 20 ~ 50 millimeters.
Above-described cathode bar material is stainless steel or lead.
The present invention compared with prior art has the following advantages:
1, the helical discharge body of this electric defroster cathode line and cathode bar are connected as a single entity when processing and manufacturing, and not later stage welding is got on, and very firmly, therefore there is not Long-Time Service and situation about coming off, ensure that the Effec-tive Function of electrostatic precipitator.
2, this cathode line adopts thread cutting edge discharging structure, and point of discharge is many, electric discharge is even, demist is effective.
3, the terminals of this cathode line adopt nut to be fixed on the cathode frame of demister, easy for installation.
4, this electrostatic precipitator spiral shell cathode line is processed by solid circles metal integral, the material such as stainless steel or lead can be selected to make according to the difference of process gas medium, intensity is high, corrosion-resistant, can effectively solve the problem that in electrostatic precipitator running, cathode line often breaks.
5, this cathode line handling ease, long operational time, electric demist is effective, has good economic benefit, social benefit and ecological benefits.
