Technical conceive of the present invention is: the present invention studies from the electrostatics Coulomb's law, the energy Coulomb force of electrostatic field
As can be known, as long as allow two static factor q in the electrostatic field
1With q
2Mutually can be the smaller the better apart from r value, if can make r → 0, then will to reach maximum be that the electrostatic field function maximizes to Coulomb force F value.
The present invention adopts " open type moves pole plate " and changes the technological process of flue gas in electric field, allows flue gas enter and flow to both sides " open type moves pole plate " from the main channel, enters adjacency channel again, and final purification gas flows out electric field.The odd column entrance point that is about to the electric field passage is open-minded, and the sealing of even column entrance point, seal by the odd column passage at the port of export, and the even column passage is open-minded, and each row's dust collecting pole plate all is penetrating, grit in so whole flue gas must enter dust collector pole with the air-flow zero distance, realized making in the Coulomb's law innovation of r → 0, make storehouse, the storehouse power F value in the Coulomb's law reach maximization, make the function of electrostatic field perform to best, indicating to make the zero-emission of electrostatic precipitator trend, so with this electrostatic field appellation that designs " coulomb electric field ", main element appellation " coulomb pole plate ", denomination of invention of the present invention is taken as " coulomb electric cleaner ";
" mobile pole plate " every row wherein move up and down, when the pole plate of having collected dust walks to nearly ash bucket position, the bottom is provided with a pair of rolling brush, clipping dust collecting pole plate brushes dust into ash bucket, do not cause secondary fly-up, add because the good fortune of coulomb electric field structure, make in the penetrating space, wind speed is than the low several times of electric field mean flow rate, more difficultly when falling ash, fly upward again, and the ash that falls also can not turn back in the main channel that enters with air-flow is reverse, again and also be furnished with corona wire in the second channel and suppressing the elegant again of dust once more, so the difficult problem of deduster secondary fly-up has also obtained effectively overcoming.
Beneficial effect of the present invention mainly shows: the energy of 1, fully having developed the electrostatics Coulomb's law with coulomb electric dust-removing process, make two static factor zero distances approaching, and make charged grit not be subjected to the influence of wind-force, and wind-force is become power-assisted grit is forced to push to dust collector pole, break through the difficult capture of high specific resistance, do not reached the bottleneck of discharging standards; The reentrainment of dust that has caused when 2, having overcome electric precipitation pole plate deashing has been broken through and has been collected the difficult problem that dust wafts and brims with once more; 3, the invention of coulomb electric cleaner, saved overall cost greatly, the volume of original conventional electric cleaner is reduced over half, the conventional need with four or five electric fields, coulomb electric cleaner needs only and just can be effective with 1-3 electric fields, and to old electric dust-removing equipment that can not be up to standard, the transformation that can get instant result, not increasing electric field can be up to standard, so no matter grassroot project or transformation for increasing productiion capacity, coulomb electric cleaner of the present invention is not only reduced investment outlay but also save the energy, meets the environmental protection state basic policy of energy-saving and emission-reduction.
