Description
Technical field:
The utility model belongs to the chemical industry environmental protection technical field, relates to a kind of electrostatic precipitator parts, relates in particular to a kind of spiral needle electricity demist cathode line.
Background technology:
electricity demist (dirt) device is to capture droplet or dust in waste gas with the High-voltage electrostatic purification method, its operation principle is after dusty gas enters electric field equably, produce corona phenomenon near corona discharge electrode, make gas ionization, there are a large amount of electronics and ion in gas after 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 by leakage fluid dram (ash exhauster), the purified gas atmosphere that enters up to standard.
With respect to other other gas cleaning plants, electricity demist (dirt) device is because of advantages such as it have that the demist rate is high, 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 the gas cleaning flow process.But due 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, removes fog effect undesirable.
The spirality cathode line have discharge evenly, electric field breakdown voltage is high, applicable thin dust, the characteristics such as easy for installation of collecting.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 easily occurs and ruptures, thereby causing the anode and cathode short circuit to force electric field to quit work in the yield limit that exceeds spring material.
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 due to 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, between the round steel of draw point and shank, boring tight fit or the electric resistance weldings of adopting are fixed more more.Boring very useless man-hour, during electric welding, round pin and circular shank are to contact, and contact-making surface is too little may affect weld strength, will bear long-term rapping impact when cathode line is moved in electric cleaner, so 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 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 purpose of this utility model is the shortcoming that exists for the cathode line prior art, and the electrostatic precipitator spiral discharge bodily form that a kind of point of discharge is many, discharge is even, intensity is high, corrosion-resistant, price is low cathode line is provided.
The utility model is achieved in that
