Description
Technical field
The present invention relates to technical field of waste treatment, relate in particular to a kind of high frequency wet type blue light dust collector.
Background technology
With the progress of technology, electrostatic precipitator is gradually applied in the processing link to garbage disposal tail gas.Electrostatic precipitator is to discharge using discharge electrode to produce plasma so that dust particale load electric charge in garbage disposal tail gas, and the garbage disposal exhaust particulate of load electric charge sticks on colelctor electrode under electrostatic attraction effect and drops from colelctor electrode.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 composition such as two English in garbage disposal tail gas, prevent toxic and harmful and flow in the 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 upper attached charged dust, the macromolecule organic principle such as tar in garbage disposal tail gas is led to be attached to the surface of insulator, these organic principles easily produce spark because discharge electrode discharges, and cause potential safety hazard.And rely on merely the work of electrostatic precipitator, nor the remove rubbish pm2.5 microparticle that process in tail gas is completely secured.In addition, traditional electrostatic precipitator adopts rustless steel as collector material, belong to direct electric discharge, power consumption is larger, and equally easily produce spark.How to overcome the problem that the problems referred to above are that those skilled in the art need thinking.
Content of the invention
For solving the above problems, the invention provides a kind of high frequency wet type blue light dust collector.
The concrete technical scheme of the present invention is as follows:
A kind of high frequency wet type blue light dust collector, including dust cleaning case and fairing；Described dust cleaning case is hollow box body, and its top is provided with gas outlet, and bottom is provided with dust hopper；It is provided with alkali mist spray pipe and blue light dust removing units inside described dust cleaning case, described blue light dust removing units are located at the underface of gas outlet, described alkali mist spray pipe is located at the underface of described blue light dust removing units, described fairing one end is the eddy flow commutator air inlet stretching out outside dedusting box body, the other end is the commutator stretching into inside dust cleaning case, and described eddy flow commutator is located at the underface of alkali mist spray pipe and the surface of dust hopper；The discharge electrode that described blue light dust removing units include multiple cellular field tubes and are located at each cellular electric field tube hub respectively；Described each discharge electrode upper end is commonly connected to resonance frame by insulator, lower end connects weight body respectively；Described cellular field tube is fixed in dedusting box body by metal cage, and described discharge electrode connects power cathode.
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 towards in dedusting box body, and this alkali spray film occurs acid-base neutralization reaction, forms the water of saliferous with the acidic materials component in garbage disposal tail gas, and continues to be moved into upward in cellular field tube under hot-air drives.Power supply is energized, discharge electrode is made to start to discharge, the hydrone in garbage disposal tail gas is made to generate electron ion, the dust granules in garbage disposal tail gas are made to adhere to upper electric charge, the dust granules that these enclose electric charge are piled up in the cellular field of points pipe surface as colelctor electrode in the presence of electrostatic attraction, and freely falling body under gravity, drop in dust hopper.And other harmless gas componants then pass through blue light dust removing units to continue to rise, finally derive dedusting box body from gas outlet.During, resonance frame produces dither under the drive of high-frequency discharge pole, 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, microgap mesh is evenly distributed with described metal sponge plate, the casing that described metal sponge plate is fixed on dust cleaning case is interior, the underface of the blue light dust removing units of surface sum that are being located at eddy flow commutator；The upper surface just to described sponge plate for the described alkali mist spray pipe.
By using this technical scheme: from eddy flow commutator, the garbage disposal tail gas of output enters in blue light dust removing units after metal sponge plate further rectification mixing, simultaneously, the fogged lye of alkali spray painting pipe inspection is mixed with garbage disposal tail gas in metal sponge plate, so that part pm2.5 dust granules and water molecules, volume in garbage disposal tail gas is become much larger thus being 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 in conventional art, purely rely on electrostatic precipitator to enter the shunting of circulation of qi promoting dirt, lead to the unnet problem of dedusting.
It is further preferred that above-mentioned high frequency wet type blue light dust collector: described cellular field tube adopts boron glass quartz ampoule.By this scheme: with respect to the prior art using 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 electric field inside pipe wall.Form photocatalyst under uv irradiation and flue gas is made with further purified treatment.
It is even furthermore preferable that in above-mentioned high frequency wet type blue light dust collector: the axial direction of described discharge electrode is distributed with uniform serrate projections.In this way: constituted point discharge effect with the serrate projections on discharge electrode surface and realize electric discharge formation plasma.
Still further preferably, in above-mentioned high frequency wet type blue light dust collector: described integrated hopper includes rotary valve and negative pressure deashing carrier；Described rotary valve one end is towards the lower surface of described sponge plate, the other end towards described negative pressure deashing carrier.
By using this technical scheme: control integrated hopper that dedusting box body outside is Turned on/off by rotary valve.When rotary valve is opened, negative pressure deashing carrier is used for for the dust in integrated hopper cleaning out dust cleaning case.
Compared with prior art, present configuration is simple, 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.
