Description
The utility model belongs to a kind of electrostatic dust collector.
Existing wide polar distance electrostatic precipitator is because pole span is wide, stable, corona is abundant, so dust collection effect is better.But in the demanding occasion of gathering dust, often needing increases a plurality of electric fields, makes floor space increase cost up.
In order to use less cleaner, with reach few occupation of land, reduce cost, the purpose of high-effective dust-removing, a kind of wide polar distance electrostatic precipitator of special invention with pre-charge and auxiliary dust collecting electrode.
The utility model is made up of for three sections charged section of static cohesion, wide polar distance electrostatic dust collection section and auxiliary control of dust section.In inlet 3 inwall both sides some high concentration ion generation sheets 2 are housed, form charged section of static cohesion.Some wide polar distance control of dust pole plates 5 are equipped with in gather dust most of space of 12 front portions, chamber, form wide polar distance electrostatic dust collection section.These pole plates are fixed on the main pole sheet frame 6, and some center corona plate 1 are housed between its pole plate, are fixed on the negative electrode frame 4, and negative electrode frame 4 hangs on the bracing frame 7.By the auxiliary control of dust section that the multilayer grooved supplementary set dirt utmost point 10 is formed, be located at the rear portion in the chamber 12 of gathering dust, be placed between wide polar distance control of dust pole plate 5 and the outlet 11.The auxiliary dust collecting electrode 10 interlaced arrangement of each layer, and be fixed on the interpole sheet frame 9.High concentration ion generation sheet 2 is made up of ceramic film 16, earthing pole 17, dielectric 18, discharge electrode 19, earthing pole terminal 15 and discharge electrode terminal 14, earthing pole 17 sintering between ceramic film 16 and dielectric 18, discharge 19 utmost point sintering are in the outside of dielectric 18.Ceramic film 16 1 sides of high concentration ion generation sheet 2 are fixed on inlet 3 inwalls.In this device, control of dust pole plate 5, the auxiliary dirt utmost point 10, earthing pole 17 be ground connection extremely all, and center corona discharge electrode 1 connects negative high voltage, and discharge electrode 19 connects the high-frequency impulse high voltage source by discharge electrode terminal 14.
Owing on discharge electrode 19, be added with hf and hv pulse, creeping discharge takes place on discharge electrode 19 surfaces, form the high concentration ion mist.When the gas of band dust by entering the mouth 3 when entering flue, the dust grain is fully charged and increase slightly by ion-atmosphere, makes grit before entering electric field, reaches and gives saturated charged purpose earlier.Because the chap of grit and the increase of carrying capacity, the Coulomb force that acts on the grit strengthens greatly, and purification efficiency significantly improves.This is the operative scenario when waiting to staticize gas by charged section of static cohesion.The gas that then carries the residue grit enters wide polar distance electrostatic dust collection section.Not only diameter is thick from charged section grit of coming of static cohesion, and carrying capacity is big, so grit jumps on the migration velocity of control of dust pole plate 5 in electrostatic field bigger.The normal pole span pole plate of wide polar distance pole plate can strengthen supply voltage, thereby the corresponding increase of electric-field intensity, and wherein near the electric potential gradient the heart corona discharge electrode 1 is more than 2 times of general cottrell, have in addition can reach several times.Simultaneously, near the most advanced and sophisticated corona point of the prickle of center corona discharge electrode 1, can produce the ion wind of taper, improve the effective migration velocity of grit greatly, help improving dust-collecting efficiency.At last, gas enters auxiliary control of dust section, and in this control of dust section, auxiliary dirt plate 10 makes the dust collecting electrode area increase more than 20%.Owing to assist the flute profile fluid field of forces that form in the collecting plate 10 and the electric field that charged grit forms all to become the composite force field of electric field, dust collection effect strengthened greatly, and be difficult for when rapping, producing the secondary fly-up of gas.Be adsorbed on dust on each pole plate of dust-precipitator by rapping, constantly fall in the ash bucket 13.Cleaned gas is discharged from exporting 11.
This utility model have floor space few, the investment little, dust-collecting efficiency advantages of higher, can purify ultra micron and high specific resistance grain dirt, be suitable for the purification of dust such as talcum powder, cement, magnesia, casting.
