Description
Technical field
The utility model belongs to the dedusting technology field, is meant a kind of traveling electrode electrostatic precipitator with the stationary brush deashing especially, is applicable to dedusting fields such as station boiler dedusting, cement plant kiln head and tail and metallurgical works, chemical industry, nonferrous metallurgy.
Background technology
At present, the capital equipment that atmospheric dust pollution is administered is electrostatic precipitator, sack cleaner and electric bag compound type dust remover.
Electric cleaner has advantages such as efficient height, running resistance is low, simple to operate, operation and maintenance cost is few.But also there is certain defective in electric cleaner, be collected in the dust on the electrode, in hammering vibration dust-cleaning process, after the single grit that is crashed to pieces returns to air-flow, carry out the charged and collection process second time again, in this staggered process repeatedly, always have the sub-fraction dust to transfer to second electric field from first electric field, and then transfer to the final stage electric field again, enter chimney at last.Therefore, the insider is almost consistent to be thought, the reentrainment of dust when reducing rapping is one of key measure that improves dust collection efficiency.Reduce the reentrainment of dust measure and mainly contain two technological approaches, the one, adopt the wet method deashing, the one, adopt the brush deashing.The wet method deashing mainly is a water spray irrigation electrode, though ash-removal effect is excellent, can bring problems such as corrosion of steel structure and sewage disposal, promotes limited amount so far.Adopt brush to remove the method for dust stratification on the electrode, China once developed in the seventies in last century, and the brush para-electric utmost point moves up and down, and its driving mechanism is installed in the electric field top.China also developed electrode design was become disc, and driving shaft slowly rotates in disc centre, and brush is fixed on the ash-clearing technology of disk both sides.But this mode exists technology barrier along with the maximization of equipment.
Abroad, Japan also develops the technology that traveling electrode adopts the rotating brush deashing in last century end.This technology is made up of the electric field of several fixed electrodes and the electric field of a traveling electrode usually, the dust collecting pole plate of traveling electrode is by the strip pole plate lateral arrangement of several separation, and connect by the driving wheel transmission by chain, drives horizontal bar shaped pole plate and turn round and move back and forth.When ash-laden gas passed through electric field, dust was caught by horizontal bar shaped pole plate under the effect of electric field electrostatic force.
Discharge electrode is installed in the centre of traveling electrode.Discharge lines adopts the discharge inception voltage height, and current density is discharge lines uniformly.
When the dust that captures on dust collecting pole plate does not reach when being enough to form the thickness of anti-corona, just be moved to the non-dust catching district that is positioned at ash bucket that does not have the flue gas circulation, the deashing brush that this dust layer is rotated is immediately removed.So not only eliminate reentrainment of dust, and made pole plate remain " cleaning ", alleviated the anti-corona effect of high resistivity dust.
But there are the following problems for this technology: the first, because brush driving mechanism driven rotary, and must cover power set, the transmission of power link of drive unit is too much, operational reliability is reduced, increase operating cost and maintenance load.The second, rotating brush axle two ends are fixed on the sliding bearing, and are very high to the requirement of axis hole concentricity.In service often because the decentraction of axis hole causes the too early wearing and tearing of bearing in reality, the driving motor energy consumption strengthens, even breaks down.After three grades of adjustings of the three, two rotating brush centre-to-centre spacing, brush silk wearing and tearing, non-adjustable between at different levels, cause brush dirt poor effect.
Summary of the invention
At the deficiency that the above-mentioned background technology exists, it is efficient, reliable that the purpose of this utility model aims to provide a kind of operation, the traveling electrode electrostatic precipitator of the band stationary brush deashing that energy consumption is low.
