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 ring aciculiform electricity except mist cathode line.
Background technology:
Electricity is to the droplet trapping in waste gas or dust with High-voltage electrostatic purification method except mist (dirt) device, its operation principle is that dusty gas is evenly into after electric field, corona phenomenon is produced near corona discharge electrode, make gas ionization, gas after ionization exists substantial amounts of electronics and ion, the droplet (dust) of these electronics and ion and entrance electric field is combined into band point particle, charged particle is gathered in electricity under the effect of electric field and removes anode and the negative electrode of mist (dirt) device, downward landing 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 except mist (dirt) device because it has except advantages such as mist rate height, stable performance, pressure drop are little, it is used widely in industries such as non-ferrous metal metallurgy, sulphuric acid and titanium white production, is the capital equipment in gas cleaning flow process. But due to many-sided reason, electricity removes mist (dirt) device and still suffers from problems at present, and especially electricity is except the cathode line of mist (dirt) device. Cathode line is the vitals of electrostatic precipitator, cathode line in the market mainly has the versions such as spiral type 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.
Spiral type cathode line have electric discharge uniformly, electric field breakdown voltage is high, be suitable for and collect fine ash dirt, the feature such as easy for installation. But, normal spiral cathode line is a kind of extension spring substantially, and pitch is only small or be zero, to be pulled into the state that pitch is very big when mounted, yield limit beyond spring material, it is easy to occurring plastic deformation to rupture, causing anode and cathode short circuit thus forcing electric field to quit work.
Twist shape cathode line has that electric field breakdown voltage is high, the feature such as uniform, easy for installation of discharging. But, common twist shape cathode line tiny causes that intensity, rigidity are more weak due to linear, there is the problems such as easy 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 big. Its draw point adopts circular prong or flat pin, and between draw point and the round steel of shank, many employing boring tight fits or electric resistance welding are fixed. Boring is given up man-hour very much, and during electric welding, round pin is point cantact with circular shank, and contact surface is too little may affect weld strength, to bear long-term rapping and impact when cathode line is run in electric cleaner, and therefore the welding requirements 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 electric current density is big. Shortcoming is that electric current distribution is uneven, and the prickle of this type of cathode line is utilized in the mode that on steel pipe, radial direction is welded, the phenomenon often fallen 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 ratio is more uniform, and shortcoming is that discharge inception voltage is higher.
Zigzag cathode line is generally made up of flat metal material, and its discharge body is lateral symmetry or the sawtooth being interspersed, and such cathode line point of discharge is less, and intensity is on the weak side.
Summary of the invention:
It is an object of the invention to the shortcoming existed for cathode line prior art, it is provided that the electricity that a kind of point of discharge is many, electric discharge is uniform, intensity is high, corrosion-resistant, price is low is except mist ring needle-shaped cathode line.
The present invention is achieved in that
A kind of ring aciculiform electricity is except mist cathode line, including cathode bar, terminals, nut, ring pin, it is characterised in that: cathode bar is solid circles metal, and on cathode bar, parallel distance arranges ring pin, the terminals at cathode bar two are helicitic texture, terminals configuration fastening nut.
It it is annular cutting edge outside above-described ring pin.
Above-described negative electrode stick length is 1��8m, the diameter 4��12mm 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 material such as rustless steel or lead makes.
This cathode line compared with prior art has the advantage that
1, this electricity is connected as a single entity when processing and manufacturing except ring pin and the cathode bar of mist cathode line, and not later stage welding is up, very firmly, is therefore absent from life-time service and situation about falling off, it is ensured that the Effec-tive Function of electrostatic precipitator.
2, this cathode line adopt ring aciculiform cutting edge discharging structure, point of discharge is many, electric discharge is uniform, except fog effect good.
3, the terminals of this cathode line adopt nut to be fixed on the cathode frame of demister, easy for installation.
4, this electricity removes mist ring needle-shaped cathode line is by solid circles metal overall processing, make according to the optional material such as rustless steel, lead of the difference processing 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, electricity is good except fog effect, has good economic benefit, social benefit and ecological benefits.
