Abstract
The present invention relates to an electric dust collector for curved surface anodes, which is composed of a box body of the dust collector, electrodes arrayed in the box body, an upper beam, a lower beam and a dust vibrator, wherein the upper beam and the lower beam are connected with the electrodes. The anode of the dust collector is formed by arranging multiple groups of anode plates of which the cross section is a curve or a broken line on the upper beam and the lower beam in parallel; the anode plates and cathode filaments are alternately arrayed in the box body, and the corresponding positions of the anode plates and the cathode filaments are provided with multiple groups of shunting baffle plates; the cross section of each anode plate of each anode can form a W shape, an S shape, a C shape, etc. The electric dust collector combines the characteristics of static electricity, parallel deflected flow, partial swirling flow, etc. to form a composite dust collecting system, and collected dust can be effectively prevented from being blown by airflow or secondary dust flying caused by powerdown can be effectively avoided. The dust collector has the advantages of small volume and corresponding cost reduction.
Description
The present invention relates to a kind of cottrell of curved surface anode, belong to environmental protection equipment.
The cottrell of present domestic use mainly contains horizontal and vertical two kinds, and electrode is board-like, flue gas bottom horizontal flow sheet or perpendicular flow, the shortcoming of this cottrell is that dust and collecting plate touch opportunity are few, the air-flow skewness, thereby efficiency of dust collection is low, the concentration of emission height.92241004 patent disclosures a kind of deflector type cottrell, be provided with dividing plate in the casing that gathers dust, the baffling mode was communicated with to increase the touch opportunity of dust and dust collecting electrode about each dust storage chamber adopted, and still still existed the disposal box space big, the cost height, the problem of dust from flying when reaching outage.
The object of the present invention is to provide a kind of cottrell of curved surface anode, replace dull and stereotyped anode, multicomponent stream dividing plate is set, simultaneously in disposal box to improve dust-collecting efficiency with the curved surface anode.
The cottrell that technical scheme of the present invention is achieved in that the curved surface anode is made up of with the lower and upper cross-member that is connected electrode, dust vibrator dust-precipitator casing, the electrode that is arranged in the casing, the anode of dust-precipitator is to be that the positive plate of curve or broken line is set up in parallel on lower and upper cross-member by many groups cross section, many group positive plates and cathode filament are staggered in casing, its correspondence position is provided with multicomponent stream dividing plate, and the cross sectional shape of plate is W shape, S shape, C shape etc.According to the different requirements of gathering dust, can also change be distributed between dust-precipitator casing inner anode pole plate and the split-flow baffles, split-flow baffles relative distance each other to be to change local electric field strength, reaches best dust collection effect.
In practical operation, dusty gas is by air inlet vertically pole plate ejection on the sunny side at a relatively high speed, and a part is hunted down on electrode, and another part is arranged electrode until air outlet backward by the dividing plate distributed flow.The recess of flue dust on the curved surface positive plate forms eddy flow, increases flue dust and is detained the dead band, thereby improved dust-collecting efficiency greatly.Because the anode of this dust-precipitator is a curved surface, its distribution local space with dividing plate again is corresponding, so resistance and little, and dust-collecting efficiency still can reach more than 80% under the situation of outage.Through the reality test, the dust concentration after the processing is far below the 0.15g/Nm of domestic general dedusting standard
30.10g/Nm with import equipment
3Standard reaches 0.034g/Nm
3, see Appendix-test report.
Describe embodiments of the invention in detail below by accompanying drawing:
Fig. 1 for dust-precipitator casing top view Fig. 2 among the A-A view figure of Fig. 1: 1 air inlet, 2 dust-precipitator casings, 3 split-flow baffles, 4 positive plate crossbeams, 5 negative electrode corona wires, 6 curved surface positive plates, 7 air outlets, 8 cathode rapping devices, 9 springs, 10 insulators, 11 negative electrode crossbeams, 12 anode vibrators 13 mouth that gathers dust
The positive plate of cottrell of the present invention (6) is in upward grouping arrangement of crossbeam (4) up and down, leave the space between each positive plate, negative electrode corona wire (5) is also corresponding with positive plate to be evenly distributed in the dust-precipitator casing, and split-flow baffles (3) is crisscross arranged between anode and cathode.According to the different requirements of gathering dust, can also change be distributed between dust-precipitator casing inner anode pole plate and the split-flow baffles, split-flow baffles relative distance each other to be changing local electric field strength, as dividing plate at interval from dredge close or from close to dredging to reach best dust collection effect.Anode and cathode is provided with vibrator respectively.Characteristics such as this cottrell collection static, parallel baffling, local eddy flow have formed a compound dust collecting system, and the dust that can prevent from effectively to be captured is by airflow scouring or because of flying upward once more that outage produces.The dust-precipitator volume is little, under the prerequisite of equal effect, and the corresponding reduction of cost.
Claims (3)
1, a kind of cottrell of curved surface anode, form with the lower and upper cross-member that is connected electrode, dust vibrator by dust-precipitator casing, the electrode that is arranged in the casing, be provided with vertical of electrode that it is characterized in that dust-precipitator with flue gas flow direction, the anode of dust-precipitator is to be that the positive plate of curve or broken line is set up in parallel on lower and upper cross-member by many groups cross section, many group positive plates and negative electrode corona wire are staggered in casing, and its correspondence position is provided with multicomponent stream dividing plate.
