The emission problem of aerosol, meet national new standard requirement, realize qualified discharge.Turned into using wet electrical dust precipitator deep purifying
One of Main way of current coal-burning power plant minimum discharge transformation.
For flue gas by wet electrical dust precipitator, the size and distribution situation of its cross-sectional flow that circulates are to influence the master of efficiency of dust collection
Want one of factor, the state of electric field inside smoke flow velocity and air flow method, electrode plate structure, electric power system and wet electrical dust precipitator
Size factor is relevant.Uneven Velocity Profiles and violent flow perturbation dramatically increase the loss of flue dust and drop,
Dedusting, fog removal performance is caused to decline.Wet electrical dust precipitator design efficiency is higher, and gas flow distribution is equal with flow velocity size distribution
Even property is bigger to efficiency of dust collection influence degree, core component of the flow straightening grid as wet electrical dust precipitator air flow method, affects
Flow Field Distribution situation, concern the dust removing effects of wet electrical dust precipitator.Existing flow straightening grid can not ensure that air-flow is well distributed
Simultaneously, additionally it is possible to improve the dust removing effects of wet electrical dust precipitator, it is necessary to improve.
The content of the invention
To solve the above problems, the invention discloses a kind of wet electrical dust precipitator pre electrified formula flow straightening grid, installation side
Just, simple in construction, cost is low, and dust removing effects lifting is obvious.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of wet electrical dust precipitator pre electrified formula flow straightening grid, it is characterised in that：Including deflector and supporting framework
Beam, the deflector is arranged for intersecting parallels, is made up of parallel and spaced discharge plate and fixed plate, discharge plate embeds
Discharge plume, discharge tip and the discharge plate vertical arrangement of discharge plume arrange that outermost end fixed plate sets energization neck, institute
State in energization neck and be provided with cathode line, the Vierendeel girder is made up of an overall outer framework and several crossbeams, and deflector passes through
The multiple grooves grafting corresponding with each crossbeam of Vierendeel girder set on the downside of fixed plate, and by being located at the breach at its fixed plate both ends
Respectively with the opposite side plugged and fixed of outer framework two.
As a modification of the present invention, the thickness of slab of the discharge plate is 30-50mm, width 10-30cm, and length is
4.5-7m。
As a modification of the present invention, the discharge plume is stainless steel jointless cathode tube, and both ends respectively set a positioning
Hole, it is easy to be fixed on discharge plate；Several 25mm fish-bone acupunctures are installed, the fish-bone acupuncture is vertically solid in the cathode tube
It is scheduled in cathode tube, discharge tip is fillet.
As a modification of the present invention, the fixed plate thickness is 3.5-6mm, length 2.5-3m.
As a modification of the present invention, the outer framework is stainless steel, outer painting glass flake, glass flake thickness
For 3.5-5.5mm.
The beneficial effects of the invention are as follows：
A kind of wet electrical dust precipitator of the present invention pre electrified formula flow straightening grid, to wet electrical dust precipitator entrance cigarette
While gas be oriented to and be uniform, embedded discharge electrode make it that entrance soot fraction is charged, improves the dedusting of wet electrical dust precipitator
Efficiency, the specific dust collection area of electric cleaner is added indirectly, and simple in construction, easy for installation, good economy performance.
