Abstract
The utility model relates to a slot-shaped dust collecting board used in an electro-precipitator. The dust collecting board is provided with two rows of dust collectors that are in parallel with each other and are arranged crossways at a way that is perpendicular to the airflow direction at an end of a collecting plate of the electro-precipitator. The section of the dust collector is a concave board and the concave faces of the two rows of dust collectors opposite to each other. The utility model can collect three parts of dust that runs away from the electro-precipitator with a reasonable structure; the volume of a normal electro-precipitator is not increased, thereby being able to effectively providing dust collecting efficiency as an electro-precipitator.
Description
Technical field
The utility model belongs to the smoke abatement device in environmental protection field.
Background technology
Conventional electric cleaner is provided with the control of dust pole plate and the corona discharge utmost point in the operating room, and dusty gas enters when purifying in the electric cleaner, will pass through usually: four processes such as the formation of electric field and gas ionization, dust be charged, gather dust, deashing.Apply high voltage direct current at corona discharge electrode, when the high-tension electricity that applies is a negative pressure, and when reaching enough voltage, discharge electrode ambient gas molecule generation ionization, the outer-shell electron of gas molecule breaks away from owing to being subjected to the free electron bump, forms new negative ions and electronics.It is just to have formed electric current that negative ions and electronics respectively flow in to its heteropole direction.When dusty gas during by electric field a large amount of anion and electronics can make dust charged attached to the dust surface.Go to a grassroots level in effect of electric field, charged dust is to its opposite polarity direction motion.In the negative corona electric field, the dust of a large amount of bear electricity is shifted to the control of dust pole plate (positive pole) of ground connection, after charged dust arrives the control of dust polar board surface, promptly discharges electric charge.These dust are assembled mutually by the statcoulomb power and the van der Waals' force of residual charge again simultaneously, attached to the surface of control of dust pole plate.Dust accumulation impacts with the beater rapping behind certain thickness again, and dust is flaked off in the ash bucket from collecting plate.Like this, four groundwork processes are finished.
Dust outside conventional electric cleaner escape electric field mainly contains three parts.First is the secondary poplar dirt when impacting deashing owing to rapping; Second portion is that the dust or the charged dust that power on of lotus do not discharge electric charge again behind the collecting plate surface, and dust is got back in the air-flow again; Third part is an also no show control of dust polar board surface of charged dust, is taken out of outside the electric field by air-flow.And above dust can cause the very big pollution of environment equally.
Of the present utility model open
The purpose of this utility model be for provide a kind of capture three outer part dust of escape electric cleaner, rational in infrastructure, do not increase the electric precipitation dust-precipitator that conventional electricity removes the volume of device dirt and can improve the electric cleaner dust-collecting efficiency effectively.
The purpose of this utility model can realize by following measure:
A kind of electric cleaner is to be provided with the parallel to each other and staggered dust collection plate of two rows in the terminal vertical gas flow direction of the collecting plate of electric cleaner with the grooved dust collection plate, and the cross section of dust collection plate is a notch plate, and the concave surface of two row's dust collection plates is relative.
The utility model has following advantage compared to existing technology:
The utility model is vertical with gas flow direction with the flute profile dust collection plate of the terminal horizontally set two rows of mutually staggered of conventional electric cleaner electric field, electric cleaner after this improves can be collected outer charged dust of escape electric field or rapping effectively and impact the secondary poplar dirt and the charged dust of taking out of that is not able to do in time again.The horizontal trough plate through the labyrinth, a part of dust-contained airflow is because inertial collision to the windward side of flute profile dust collection plate, makes dust fall into ash bucket.In addition, the dust of some band anion moves to connecing anodal flute profile dust collection plate, is adsorbed on the dust collection plate surface.The flute profile dust collection plate is recessed to have garden arc ditch to internal orifice, and dust-contained airflow produces eddy current through this, and dust also can stick in the arc ditch of garden.
The utility model can be widely used in the tail flue gas dust removal of coal-burning power plant's all kinds boiler and the smelting furnace of metallurgy industry, the flue gas ash removals such as rotary kiln in cement plant.Compare with conventional electric cleaner, the utility model structure can improve dust-collecting efficiency effectively under identical ratio corona discharge power, have remarkable environmental benefit and economic benefit.
The drawing explanation
Fig. 1 is a structural representation of the present utility model
1-dust collection plate 2-discharge electrode 3-collecting plate
Embodiment of the present utility model
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:
With reference to Fig. 1, many row's collecting plates 3 and discharge electrode 2 are arranged in this electric cleaner work; Collecting plate 3 terminal vertical gas flow direction at electric cleaner are provided with the parallel to each other and staggered dust collection plate 1 of two rows, and the cross section of dust collection plate 1 is a notch plate, and the concave surface of two row's dust collection plates 1 is relative.The length ratio of the length of side A B high with it of described flute profile dust collection plate 1 is 1: 0.5.The length ratio of the clearance C of flute profile dust collection plate 1 is 1: 0.55 in the length of side A of flute profile dust collection plate 1 and the adjacent cells.The length ratio of the ultimate range D of the plate hight B of flute profile dust collection plate 1 and two row's dust-precipitators 1 is 1: 2.The plate hight B of flute profile dust collection plate 1 and the ratio of the shortest height E of himself are 1: 0.3.The R value of the recessed lonely face of flute profile dust collection plate 1 is 9-20 °.
During above ratio reasonable disposition, when the clearance C of airflow passes two flute profile dust collection plates, actual internal area diminishes, flow velocity increases, air-flow becomes big at the area of I-I section, flow velocity lowers also in that the flute profile dust collection plate is recessed and forms eddy current to arc place, internal orifice garden, has strengthened separating of dust and air-flow when eddy current forms, under the effect of eddy current and Coulomb force, band anion dust is attracted on the flute profile dust collection plate 1 recessed surface and reaches in the arc ditch of garden.Like this, not only can collect the outer charged dust of electric field of escaping out effectively, and the air-flow distribution quality in the electric field is also improved.
