Description
Technical field
The present invention relates to the electric precipitator electrodes of a kind of removal metallic dust or graphite dust or carbon powder dust.
Background technique
Those skilled in the art thinks, metallic dust or graphite dust or carbon powder dust since specific resistance is too low, when
When dust reaches the collecting electrode of electric precipitator, since the speed that it discharges charge is too fast, discharge time is too short, causes dust electric
Electro Sorb dust particles are in time in pole not yet, which just has become uncharged neutral dust particles, thus allow
Metallic dust or graphite dust or carbon powder dust are difficult to be captured by collecting electrode, and reenter the metallic dust or stone of air-flow
Thus toner dust or carbon powder dust enable electric precipitator efficient to containing then mostly all as air-flow passes through electric precipitator
The gas of metallic dust or graphite dust or carbon powder dust carries out dust removing.
It is generally believed that the specific resistance range of optimum electric precipitator work is 104—5×1010Ω*cm.When dust is than electricity
Resistance is too low, is lower than 104Ω * cm (such as carbon powder dust) releases charge thereon after dust reaches dedusting extremely quickly, becomes
Property, it is easy to fall off from dedusting extremely, reenters air-flow, generate reentrainment of dust, reduces efficiency of dust collection.When dust specific resistance too
Height is higher than 1011When Ω * cm, after dust reaches dedusting extremely, dust-charge is not easy to discharge, and is gradually deposited at the powder of dedusting pole surface
Dirt is still negative polarity, and it is newly attached thereto that it repels subsequent dust, after dust layer reaches certain thickness, the shape inside dust layer
At certain electric field, dust layer surface is negative pole, and dedusting is extremely positive.Dust layer thickens, and electric field strength increases, so that dust layer
Interior air breakdown releases a large amount of cations from dedusting pole to dedusting space to generate back discharge (referred to as inverse corona),
So that dust charge positive electricity is entered dedusting space, destroys normal dedusting work.
It is lower for specific resistance, after depositing to dedusting extremely, need to remove from dedusting is extremely upper as soon as possible, in order to avoid influence dedusting
The efficiency of dust collection of device.For the relatively low characteristic of cracking micronex specific resistance, lasting spray is carried out using soft water, once carbon black
Charge is released on pole plate, then is taken away immediately by spray soft water, to alleviate reentrainment of dust.Also, it is transported in electric precipitator
After the certain event of row, pole plate and polar filament are sprayed using larger amount of periodic flushing water, adhered to thereon with removing a large amount of
Carbon black, to extend the cycle of operation of electric precipitator.
The dust being deposited on collecting electrode is aggregated into aggregate because adhering to each other, after rapping electrode, their energy
It freely drops in ash bucket, will not be entrained by the flow of air under the effect of gravity, still, if the specific resistance of dust is less than 103~
104Ω cm then not only loses charge after it reaches dust collecting surface immediately, but also immediately by electrostatic induction acquisition and the electricity that gathers dust
The positive electricity of pole same polarity.If the repulsive force that positive electricity is formed, large enough to overcome the adhesion strength of dust, the ash deposited is heavy
Drop leaves collection electrode and returns to air-flow.But because in space by ion collision, and can regain and discharge electrode homopolarity
The negative charge of property and moved to collecting electrode, be as a result formed in the phenomenon that jumping on collecting electrode, may finally be taken out of by air-flow
Electric precipitator.Various metallic dusts and graphite dust, carbon powder dust are handled it can be seen that this phenomenon with electric precipitator.
The method for cyclone dust collectors of connecting behind electric precipitation gas can be often taken such case to solve.Because taking
Particle with different charge may integrate big particle by frequent collision, can cross and separate in cyclone dust collectors.Example
As carbon black can be trapped with the method for cyclone dust collectors of connecting behind high speed electric precipitator.In addition, can or can not jump
Phenomenon and the adhesiveness of particle are related.As the carbon black dust of heavy oil boiler, SO is adhered on surface3And tar, although than electricity
It hinders small, accumulation can be also adhered on collecting electrode, therefore generally can effectively be trapped.
In order to solve the problems, such as to be collected low resistivity dust with electric precipitator, those skilled in the art is proposed with conductive
Applying coating collecting electrode makes polar board surface form the coating with certain specific resistance, reduces metallic dust or graphite with this
The speed of dust or carbon powder dust release charge.But our analysis and experiment all shows only to apply dust with conductive coating
The effect is unsatisfactory for electrode, reduction metallic dust or graphite dust or carbon powder dust release charge speed, because even mentioning
The specific resistance range that the resistance of high collecting electrode to suitable electric precipitator works, metallic dust or graphite dust or carbon powder dust sheet
The resistance of body is still low-down, and metallic dust or graphite dust or carbon powder dust with high voltage electricity touch by
The moment for improving the collecting electrode of resistance due to the sufficiently bulky of collecting electrode and remains ground connection, dust itself
This still low-down feature of resistance allows metallic dust or graphite dust or carbon powder dust still can be complete in the very short time
At electric discharge, brought discharge lag effect is limited to the influence for improving efficiency of dust collection, and experiment shows that it is micro- 20 to partial size
Meter or more the efficiency of dust collection of graphite dust be no more than 95%, the efficiency of dust collection to partial size in 10-15 microns of graphite dust is
90% or so, to partial size 2.5 microns of graphite dusts below efficiency of dust collection less than 50%, that is to say, that it can reach
Efficiency of dust collection be unable to satisfy the environmental requirements of most of production technologies.
