Specific embodiment
The present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.
Embodiment 1
It as shown in Figs. 1-2, is a kind of electric precipitator c-type anode plate described in the embodiment of the present invention, which includes:
Anode plate inclined-plane 1 is provided close at the position of the draught-proofing channel of c-type anode plate, along the length direction of draught-proofing channel
Setting；
Through-hole 2 is uniformly arranged on anode plate inclined-plane 1.
Existing c-type anode plate is not provided with through-hole 2, therefore when carrying out vibration dust-cleaning to c-type anode plate, due to rapping
The effect of power and flue gas flow rate, the phenomenon that causing the c-type anode plate draught-proofing channel back side there are dust escapes.In order to make up this not
Foot, the present invention have been uniformly arranged through-hole 2 on the anode plate inclined-plane 1 of c-type anode plate.It is clear that rapping is carried out in c-type anode plate in this way
When grey, the dust at the c-type anode plate draught-proofing channel back side can enter c-type sun due to the effect by horizontal direction air-flow via through-hole 2
In the draught-proofing channel of pole plate.Therefore dust can then gather in the draught-proofing channel of c-type anode plate, to reduce dust escape, into one
Step improves the efficiency of dust collection of electric precipitator.
Further, through-hole 2 is the circular hole or 6mm × 10mm~8mm × 20mm slotted eye of 6~8mm of diameter.This reality
Apply that through-hole in example selects is circular hole, is not limited to circular hole in a particular application, the concrete shape of through-hole 2 can be according to processing
Comfort level be determined.It is also not specifically limited as the specific size of through-hole 2, it in actual use can be according to dust
Particle diameter distribution determine the specific size of through-hole 2.
Further, the percent opening of through-hole 2 is the 40%~65% of 1 area of anode plate inclined-plane.Through-hole 2 in the present embodiment
Percent opening be arranged between 40%~65% range, can be come according to dust concentration in electric precipitator in specific operating condition true
Higher percent opening then may be selected in the percent opening for determining through-hole 2 when concentration is larger, when concentration is smaller if can suitably reduce through-hole 2
Percent opening.
The width for the c-type anode plate selected in the present embodiment is 480mm, i.e. the c-type anode plate of 480 types.It is actually using
In, the design for the through-hole 2 that the present invention is done can equally be well applied to the c-type anode plate of other models.
Embodiment 2
As shown in figure 3, being a kind of electric precipitator described in the embodiment of the present invention, which includes:
C-type anode plate 3, opposite two-by-two to be horizontally placed on inside dirt pocket 4 for one group, two adjacent C of horizontal direction
The draught-proofing channel of type anode plate 3 is contrary, and c-type anode plate 3 is equipped with anode plate inclined-plane 1, anode plate at the position of draught-proofing channel
The length direction on inclined-plane 1 is equipped with through-hole 2；
Air inlet smoke box 5 is set to the side of dirt pocket 4；
Outlet smoke box 6 is set to the other side of dirt pocket 4；
Ash bucket 7 is set on the dirt pocket 4 immediately below c-type anode plate 3.
Further, the draught-proofing channel for two c-type anode plates 3 being oppositely arranged is opposite or is disposed opposite to each other.
Air inlet smoke box 5 is arranged in the left side of deduster 4 in the present embodiment, and outlet smoke box 6 is arranged on the right side of deduster 4,
Ash bucket 7 is arranged in the bottom end of deduster 4, c-type anode plate 3 is arranged in the inside of dirt pocket 4, wherein c-type anode plate 3 is in dirt pocket 4
Internal arranged side by side and interlaced arrangement.I.e. two c-type anode plates 3 form a column, and the draught-proofing channel such as the c-type anode plate 3 of first row is opposite
Arrangement, then the draught-proofing channel of the c-type anode plate 3 of secondary series is then positioned opposite, and the draught-proofing channel of tertial c-type anode plate 3 is with respect to cloth
It sets, according to such arrangement mode and so on.Such set-up mode can make from the 3 draught-proofing channel back side of previous column c-type anode plate
The dust of escape is intercepted by the draught-proofing channel of next column c-type anode plate 3.To reduce the escape of the dust in electric precipitator, improve
Its efficiency of dust collection.In use, flue gas is entered in deduster 4 by air inlet smoke box 5, by the absorption of multiple groups c-type anode plate 3
Dust in flue gas, by being discharged in outlet smoke box 6, the dust that c-type anode plate 3 is absorbed then is given by ash bucket 7 final neat stress
It collects.
Further, c-type anode plate 3 is equipped with multiple groups, and ash bucket 7 and the mating setting of multiple groups c-type anode plate 3.
Further, every group of c-type anode plate 3 is equipped with corresponding rapping apparatus.
Each group of c-type anode plate 3, which is matched, is arranged with a rapping apparatus and an ash bucket 7, and used rapping apparatus
For frequency conversion rapping apparatus, rapping apparatus is then enabled after the dust in c-type anode plate 3 is built up to a certain degree and it is carried out clearly
Reason, can be used lower frequency to carry out rapping to c-type anode plate 3 when just beginning a clean up can be such that dust falls into its correspondence ash bucket 7,
And to the end, the location of dust and the adhesive force between dust and c-type anode plate 3 are all bigger in c-type anode plate 3, because
This needs to open the upper frequency of rapping apparatus, and just the dust in c-type anode plate 3 can in this way fallen into its corresponding ash bucket 7.
Further, it is 1 area of anode plate inclined-plane that through-hole 2, which is evenly arranged in anode plate inclined-plane 1 and the percent opening of through-hole 2,
40%~65%.
Through-hole 2, which is evenly arranged, can make the dust in c-type anode plate 3 everywhere by airflow influence, and be unlikely to make powder
Dirt all accumulates in the somewhere of c-type anode plate 3.The percent opening of through-hole 2 is arranged between 40%~65% range in the present embodiment,
The percent opening of through-hole 2 can be determined according to dust concentration in electric precipitator in specific operating condition, it is then optional when concentration is larger
Select higher percent opening, when concentration is smaller if can suitably reduce the percent opening of through-hole 2.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
