Description
Technical field
The utility model relates to a kind of electrostatic precipitator for removing industrial fumes particle, is specifically related to a kind of electrostatic precipitation by type positive plate.
Background technology
Electrostatic precipitator in dust cleaning case, is provided with corona discharge wire coordinate many sedimentation passages formed with collecting polar plate, corona discharge polar curve applies direct current negative polarity high-tension electricity, make its anion releasing, for the smoke particle in charged dust-contained airflow, on collecting polar plate, apply straight polarity high voltage, for collect charged after negative polarity smoke particle, then, by rapping mode, the flue dust that collecting polar plate is collected is shaken off in the ash bucket of bottom, thus reach the object of the smoke particle removed in air-flow.
Electrostatic precipitator positive plate is the core component of electric cleaner, and according to square being inversely proportional to of Coulomb's law (electrostatic force law) known Coulomb force and distance, the active force between two point charges is directly proportional with their electricity product.Known distance is shorter, and electrostatic adsorption force is stronger.But flue dust is from charged to absorption, need, through one section of longer distance, electrostatic adsorption force will certainly be caused more and more weak with the increase of distance; If but shortened positive plate, also could affect smoke catching power, thus flue dust is discharged with air-flow, not reach the object of effective dedusting.
The electrostatic precipitator of prior art, the positive plate that gathers dust in its electric field, is the plate armature of shield type, and major part is the closed fixed polar plate of impermeable vertical hanging tabular.The trapping ability of this kind of positive plate to flue dust is limited, and when vibration dust-cleaning, dust can be kicked up with air-flow again, causes reentrainment of dust.
Utility model content
Utility model object: the purpose of this utility model is to solve the deficiencies in the prior art, provides one to be easy to adsorption of dust, to be easy to deashing, can effectively prevent the electrostatic precipitation of reentrainment of dust by type positive plate.
Technical scheme: in order to realize above object, a kind of electrostatic precipitation described in the utility model is by type positive plate, and comprise plate body, described plate body both sides are respectively upper junction plate and lower connecting plate; The anode lath that at least one is equidistantly arranged in parallel is comprised in the middle part of described plate body; Described anode lath is horizontally installed with at least one fixed strip; Described anode lath is provided with air-flow through hole.
The aligned gaps of the lath of anode described in the utility model is gas channel; At inlet end, described gas channel is that opening state and closed state are spaced successively; In outlet side, opening state and the closed state of described gas channel are contrary with inlet end.After air-flow admission passage, change the track that moves forward of original conventional dust removal device, but turn round to both sides diffusion motion, decrease the move distance of dust, add electrostatic adsorption force, can effective adsorption of dust.
The inlet end of gas channel described in the utility model is provided with deflector.The flowing velocity of charged dust is changed by deflector.
Deflector described in the utility model is that symmetrical inclination is installed.Dust leads the air-flow through hole direction motion of anode lath by deflector, reduces the move distance of dust, increases electrostatic force.
Optionally, the through hole of air-flow described in the utility model is circular or rectangle or square.
Beneficial effect: compared with prior art, the utility model has the following advantages:
1, the lath of anode described in the utility model is provided with air-flow through hole, and at gas channel, opening of interval and closed state are set, the track that moves forward of original conventional dust removal device is changed after making air-flow admission passage, turn round to both sides diffusion motion, flue gas flow rate reduces, in flow field, gas flowing is almost laminar flow, dust natural subsidence.The dust descended slowly and lightly after shaking can not be kicked up by air-flow again, has thoroughly stopped the possibility of reentrainment of dust.
2, the inlet end of gas channel described in the utility model is provided with deflector, and deflector is symmetrical tilt to install, and can change flowing velocity and the flow direction of charged dust, reduce the move distance of dust, increase electrostatic force, can effective adsorption of dust.
Accompanying drawing explanation
Fig. 1 is that the utility model electrostatic precipitation is by type anode construction schematic diagram.
Fig. 2 is the utility model deflector structure details drawing.
Fig. 3 is the utility model anode battened construction details drawing.
In figure: 1 plate body, 2 upper junction plates, 3 lower connecting plates, 4 anode laths, 5 fixed strips, 6 air-flow through holes, 7 inlet ends, 8 outlet sides, 9 deflectors, 10 installing holes, 11 locating holes.
detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
A kind of electrostatic precipitation is as Figure 1-3 by type anode, and comprising: plate body 1, described plate body 1 both sides are respectively upper junction plate 2 and lower connecting plate 3; The anode lath 4 that at least one is equidistantly arranged in parallel is comprised in the middle part of described plate body 1; Described anode lath 4 is horizontally installed with at least one fixed strip 5; Described anode lath 4 is provided with air-flow through hole 6.
The aligned gaps of described anode lath 4 is gas channel 5; At inlet end 7, described gas channel 5 is spaced successively for opening state and closed state; In outlet side 8, opening state and the closed state of described gas channel 5 are contrary with inlet end 7.
Described gas channel 5 inlet end 7 is provided with deflector 9.
Described deflector 9 is that symmetrical inclination is installed.
Described air-flow through hole 6 is rectangle.
When the utility model is implemented, by locating hole 11, upper junction plate 2 is hung location, then be screwed the installing hole 10 of upper junction plate 2 and lower connecting plate 3.Charged air-flow enters gas channel 5 from inlet end 7 by deflector 9, and towards the air-flow through hole 6 of anode lath 4 to both sides diffusion motion.The flow velocity of Primordial Qi stream is 0.8m/s, causes air-flow velocity to be reduced to 0.2m/s, dust natural subsidence because cross section increases suddenly.Rapping anode lath 4 carries out deashing, and the dust descended slowly and lightly after shaking can not be kicked up by air-flow again, has thoroughly stopped the possibility of reentrainment of dust, has improve efficiency of dust collection.
