Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, Fig. 2, the invention mainly comprises air outlet 1, dust collection module in electrode 2, needle point discharge module 3 is just imitated
Filtering module 4, return air inlet 5, fresh wind port 6, wind turbine 7, transformer 8, high-pressure modular 9.The return air and fresh air of required processing lead to respectively
It crosses after return air inlet 5 and fresh wind port 6 mix according to a certain percentage, first by primarily efficient filter module 4, mixing air is carried out
Primarily efficient filter improves the charged of charged particle ratio and single particle in pending air later by needle point discharge module 3
Amount, to improve collection efficiency, with this slow down filter efficiency of dust collect plant in electrode with hold dirt decaying, subsequently into
The dust collection module of electrode captures air atom, and finally via wind turbine 7, by treated, air is sent out by air outlet 1.
To 2 efficiency of dust collection module in electrode with the problem of dirt is substantially decayed is held, by increasing needle point discharge module 3 in front end
It makes improvements, increases the carrying capacity of charged particle ratio and single particle with this, to improve collection efficiency.Such as Fig. 5,
Needle point discharge module 3 is made of corona pin and aluminum orifice plate, and corona pin assigns on the non-conductive socket of holder, and is fixed on conduction
On item, it is connected to high direct voltage module and is applied in negative high voltage with -12kV or so；The plate earthing of aluminum hole, single pore radius are
20mm, since gas ionization acts on, the particle in dust-contained airflow enters dust mould by taking a certain amount of charge after circular hole
Block 2 is captured in high field.Before holding dirt experiment and carrying out and during progress, if being not turned on power supply module, rely solely at this time
The residual charge on collecting polar plate polymer surface is not enough to the attraction of charged particle to improve reliable dust collecting effect, then measures
Filter efficiency is very undesirable.
The high voltage power supply of novel dust collection module in electrode 2 accesses carbon fiber guiding conductive film by conducting wire, using negative power transmission system
System, plus earth can effectively reduce electrification to form extremely strong electric field in the minimum spacing of micro channel using negative power transmission
Phenomenon is learned, conducting wire etc. is avoided to react and corrode, while reducing many extraneous factors to influence it.Film outer wrapping
The extremely low dielectric substance of conductivity forms confined space, therefore electrode is not exposed in air, and particulate matter also can not be with electricity
Pole plate is in direct contact, and prevents from slowing down resistance change caused by ageing of electrode fracture because high voltage generates spark phenomenon between electrode,
And prevent water when cleaning from being contacted with electrode.
Particulate matter, which is collected into, to be layering, on staggered collecting plate, this module is by being subject to the attraction of grit
It collects, is equivalent to the function of filter.Each collecting polar plate is made of three-decker：Polypropylene (PP) film 12- carbon
Fiber conductive film 11- polypropylene films 12 are equally connected between each pole plate with polypropylene (PP) material and support and be partitioned into perhaps
Multiclass is like rectangle (5 × 2mm2) micro channel.12 long 550mm wide 50mm of polypropylene film, upper layer and lower layer are superimposed thickness
0.5mm, surface asymmetric fin outstanding increase the specific surface area of wall surface, are conducive to the collection of particulate matter.Using print film
Method carbon fiber guiding conductive film 11 is set between two layers of polypropylene film 12.
As shown in Figure 3,4,11 (510 × 30mm of conductive film2) using metal oxide, carbon, macromolecule conducting material with
Carbon fibre composite is made in adhesives.Each collecting polar plate is embedded into the high pressure of both sides -10kV or the electrode of ground connection
In, generate the potential difference between two adjacent plates.Conductive film 11 is wrapped in completely between electrode 10 and polypropylene film 12
Closed structure, it is adequately protected because of the insulation of PP materials, prevents from because high voltage generates spark phenomenon subtracting between electrode
Resistance change caused by slow ageing of electrode fracture, and prevent water when cleaning from being contacted with electrode.Collecting polar plate overall package exists
In plastics outline border, outline border size is 552 × 505 × 55mm, edge thickness 15mm, the plastics reinforcing rib of intermediate horizontal width 5mm,
Therefore collecting plate region effective filtration area is 520 × 470mm2.The contact contact of two evaginations is sent out with high-voltage electricity above plastics outline border
Raw module 9 connects, and high-pressure modular 9 is electrically connected by DC communication power supply changeover device with the 220V of input exchanges.
Whole device is designed with third gear air quantity, and total blast volume is respectively 60,150,240m3/ h, can be by control return air inlet air quantity
Realize control.All-fresh air pattern is only suitable for outdoor air pollution not serious situation, can by be turned up return air air quantity gear to
Make indoor accelerated test removal faster.
Finally, it should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although Shen
It asks someone to describe the invention in detail with reference to preferred embodiment, it will be understood by those of ordinary skill in the art that, to this hair
Bright technical solution is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered at this
In the right of invention.
