Description

High frequency wet type blue light dust collector
Technical field
This utility model relates to technical field of waste treatment, relates in particular to a kind of high frequency wet type blue light dust collector.
Background technology
Along with the progress of technology, electrostatic precipitator is gradually applied in the processing link to garbage disposal tail gas.Electrostatic precipitator is to utilize discharge electrode electric discharge to produce plasma so that the dust particale load electric charge in garbage disposal tail gas, the garbage disposal exhaust particulate of load electric charge sticks to drop on colelctor electrode and from colelctor electrode under electrostatic attraction effect.And effectively the dust particale being mingled in garbage disposal tail gas is separated.Meanwhile, the discharge effect of discharge electrode can effectively open the phenyl ring of the compositions such as two English in garbage disposal tail gas, stops toxic and harmful and flows in air.But, there are so some problems in traditional electrostatic precipitator: in order to avoid electric field short circuit, one end of discharge electrode is provided with insulator.And insulator easily adsorbs attached charged dust, causing the macromolecule organic principle such as tar in garbage disposal tail gas to be attached to the surface of insulator, these organic principles easily produce spark because of discharge electrode electric discharge, cause potential safety hazard.And rely on merely the work of electrostatic precipitator, the remove rubbish PM2.5 microparticle that process in tail gas can not be completely secured.It addition, traditional electrostatic precipitator uses rustless steel as collector material, belonging to directly electric discharge, power consumption is relatively big, and the most easily produces spark.How overcoming the problems referred to above is the problem that those skilled in the art need thinking.

By using this technical scheme: pending garbage disposal tail gas is entered by air inlet, uniformly enters dust cleaning case box house after eddy flow rectifier rectification.Meanwhile, alkali mist spray pipe starts to spray alkali mist in dust cleaning case casing, and this alkali spray film and the acidic materials component generation acid-base neutralization in garbage disposal tail gas react, formed the water of saliferous, and continue to be moved into upward in cellular field tube under hot-air drives.Power supply is energized, discharge electrode is made to start electric discharge, the hydrone in garbage disposal tail gas is made to generate electron ion, make the upper electric charge of dust granules attachment in garbage disposal tail gas, these are enclosed the dust granules of electric charge and pile up at the cellular field of points tube-surface as colelctor electrode under the effect of electrostatic attraction, and freely falling body under gravity, drop in dust hopper.Other harmless gas componants then continue to rise through blue light dust removing units, finally derive dust cleaning case casing from gas outlet.During, resonance frame produces dither under high-frequency discharge pole drives, and prevents charged dust granules to be adsorbed onto insulator surface.Thus, prevent the organic molecules such as the tar in garbage disposal tail gas to be attached to the surface of insulator, improve the safety during whole electrostatic precipitation.
Preferably, above-mentioned high frequency wet type blue light dust collector also includes metal sponge plate, being evenly distributed with microgap mesh on described metal sponge plate, described metal sponge plate is fixed in the casing of dust cleaning case, is positioned at the underface of the blue light dust removing units of the surface sum of eddy flow commutator;Described alkali mist spray pipe just upper surface to described sponge plate.
By using this technical scheme: enter in blue light dust removing units after from eddy flow commutator, the garbage disposal tail gas of output is mixed by the further rectification of metal sponge plate, simultaneously, the fogged lye of alkali mist spray pipe injection mixes with garbage disposal tail gas in metal sponge plate, makes part PM2.5 dust granules and water molecules, volume in garbage disposal tail gas become much larger thus is filtered without entering in blue light dust removing units by sponge plate one step ahead.Decrease the pressure of blue light dust removing units separation dust granules, overcome and conventional art purely relies on electrostatic precipitator carry out gas dirt shunting, cause the problem that dedusting is the cleanest.
It is further preferred that above-mentioned high frequency wet type blue light dust collector: described cellular field tube uses boron glass quartz ampoule.By this scheme: relative to the prior art of use stainless steel tube, boron glass quartz ampoule belongs to dielectric barrier discharge, has preferable insulating properties, there is not colelctor electrode and produce pyrophoric problem.It may further be preferable that in above-mentioned high frequency wet type blue light dust collector: scribble photocatalysis layer on described cellular field tube inwall.Form photocatalyst under uv irradiation and flue gas is made further purified treatment.
It is even furthermore preferable that in above-mentioned high frequency wet type blue light dust collector: the axial distribution of described discharge electrode has uniform serrate projections.In this way: constituted point discharge effect with the serrate projections on discharge electrode surface and realize electric discharge formation plasma.
The most preferably, in above-mentioned high frequency wet type blue light dust collector: described dust hopper includes rotary valve and negative pressure deashing carrier;Described rotary valve one end towards the lower surface of described sponge plate, the other end is towards described negative pressure deashing carrier.
By using this technical scheme: control dust hopper by rotary valve and dust cleaning case casing outside is Turned on/off.When rotary valve is opened, negative pressure deashing carrier is for cleaning out dust cleaning case by the dust in dust hopper.
Compared with prior art, this utility model simple in construction, it is easy to accomplish.Overcome insulator in discharge electrode discharge process and produce pyrophoric potential safety hazard, improve the elimination effect of dust granules in garbage disposal tail gas, effectively eliminate the poisonous and harmful element in tail gas.
