Embodiment：
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, below
With reference to being specifically illustrating and embodiment, the present invention is furture elucidated.
Embodiment 1：
As shown in Fig. 1,2,3,5, a kind of electric precipitator flows into device of air, including sets some distributions at air inlet 1
Plate 2, distribution grid 2 include overall rectangular frame 3, and frame 3 is equipped with the porous plate 4 with uniform through bore, and porous plate 4 is equal
Even arrangement hangs with the deflector 5 for guiding air-flow on the frame 3 and on porous plate 4, and deflector 5 includes being integrally conical shape
Body 51,51 end face of body is equipped with hook 52 and body 51 52 is hung on porous plate 4 via hook.
But in the prior art, the flue gas of dust-laden is entered directly into electric precipitator, and this benefit is need not be to cigarette
Gas does any processing, time saving and energy saving, but this way can make it that the smoke distribution for entering electric precipitator is uneven so that
Working condition in electric precipitator is different, and part of smoke integrated distribution causes the region electric in a certain region of electric precipitator
The efficiency of dust collection of deduster reduces, and dedusting is not thorough, and the flue gas after electric precipitator is handled, which is appointed, so contains a large amount of flue gases, arranges
Environment can be polluted after putting, not reach expected dust removing effects.A kind of electric precipitator provided by the invention flows into gas dress
Put, by being equipped with distribution grid 2 at the air inlet of traditional electric precipitator, the porous plate 4 being uniformly provided with the distribution grid 2 can
For hanging deflector 5, guiding flue gas is flowed, when the flue gas flow rate in 1 somewhere of air inlet is big, the porous plate at this
4 hang a certain number of deflectors 5, guide flue gas flow equalizing, enter so as to fulfill flue gas is uniform and stable in electric field, so as to fulfill
Flue gas is uniformly distributed in electric field, improves efficiency of dust collection；By being equipped with distribution grid 2 at the air inlet of traditional electric precipitator,
The porous plate 4 being uniformly provided with the distribution grid 2 can play the role of reducing flue gas flow rate, be removed when exterior flue gas enters electricity
During dirt device, it can be collided to fall so as to fulfill the ash fall of larger particles with porous plate 4, by the flue gas flow rate of porous plate 4
Also it is further to reduce, so that the electric field in electric precipitator fully adsorbs dust, lift efficiency of dust collection.
As shown in figs. 1 and 3, distribution grid 2 is disposed in parallel relation to one another for 2 and distribution grid 2, and 2 spacing of distribution grid is
600mm, so can further reduce the flow velocity of flue gas, so that the electric field in electric precipitator is filled equipped with two distribution grids 2
Divide absorption dust, lift efficiency of dust collection.
As shown in Fig. 1,2 and 4, bunker wall vibration device 6 is additionally provided between distribution grid 2, the vibrating rod 61 on bunker wall vibration device 6
External part is located at the center of distribution grid 2, and vibrating rod 61 is connected via distribution grid 2 of the rapping seat 62 from 1 one end of air inlet, point
Fabric swatch 2 is connected to form one via steel plate 7 and realizes deashing at the same time via bunker wall vibration device, in this way, due on distribution grid 2
Deflector 5 and porous plate 4 are directly and smoke contacts, porous after electric precipitator, which flows into device of air, uses a period of time
A large amount of dusts can be gathered on plate 4 and deflector 5, on the one hand these dusts can cause the workload of filter bag to increase, on the other hand meeting
Block porous plate 4 so that the work efficiency drop of electric precipitator is enough to porous plate 4 and deflector 5 using bunker wall vibration device energy 6
Carry out deashing so that the present invention remains good working order.
Embodiment 2：
As shown in the figure, the present embodiment structure and 1 structure of embodiment are essentially identical, something in common no longer repeats, difference
It is, distribution grid 2 is two, and the through hole of the porous plate 4 on two distribution grids 2 is staggered mutually, in this way, working as flow at high speed
Flue gas via outside distribution grid 2 through when, part of smoke can and porous plate 2 collide, realize the dusts of larger particles into
Row sedimentation, when distribution grid 2 of the flue gas by outside, it is impossible to which, perpendicular through the second distribution grid 2, flue gas can be with inner side distribution grid
Collision is produced, can not only so realize the secondary settlement of dust in flue gas, also achieves the secondary reduction of speed of flue gas, so that
Must be uniform and stable by the flue gas flow rate of current equalizer, so that the electric field in electric precipitator fully adsorbs dust, lifting removes
Dirt efficiency.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited to
