Description
Technical field
It is the present invention relates to a kind of new blower fan field of air more particularly to a kind of with the unidirectional of plasma electrostatic depuration function
New blower fan.
Background technology
With the improvement of people ' s living standards, house level is also increased substantially, and house is universal via past tile-roofed house
Steering structure rationally, insulation and the Modern Residence of good seal performance, but the house of modernization also brings a series of problems, wherein
A problem be exactly indoor air quality issues.Because with the progress of residence technology, precision of the Modern Residence when building
That spends is increased substantially so that the sealing of house is also increased substantially, and the raising of house seal is except bringing heat-insulating property
Improve so as to bring outside the improvement of living conditions, if also bringing a problem for guarantee IAQ, because people
Daily life needs constantly consumption oxygen, produces carbon dioxide, that is, the environment of people's life needs to be continuously replenished fresh air,
Else if can be had a strong impact in being chronically at the closed environment of no fresh air supplement it is healthy, therefore for the modern times
VMC is very important household equipment for house.
VMC is generally divided into unidirectional VMC and heat exchange VMC, and heat-exchange system refers to indoor confession
When answering fresh air, while extract room air again carries out heat exchange with the fresh air to indoor supply, so as to avoid summer sizzler
And thermal loss during winter cold day unlatching air-conditioning, reach the purpose of energy-conservation.Side of the heat exchange VMC according to heat exchange
Formula, wherein also a kind of heat exchange system, so-called heat exchange system is exactly in addition to the heat exchange of air, also
There is the exchange of the moisture in air, so as to avoid season of summer and winter from opening the drying of the room air in the case of air-conditioning.
But regardless of VMC, these systems are all inevitably present a problem：Runed for a long time
Cheng Zhong, the dust of the institute's band in the continuous entrapped air of the place such as new blower fan and pipeline, inlet and outlet meeting, these dust long term accumulations
Often breed bacteria afterwards, so as to healthy be caused damage what is unconsciously given people.
Meanwhile, especially haze problem has become the social concern of China, the haze of autumn and winter to air quality problems
The haze of particularly northern area has become a kind of whole people's memory.Therefore, air purifier has become China resident, it is special
It is not the important living electric apparatus of city dweller, and also be incorporated into purification of air in VMC by some VMCs, to fresh air
Purified to improve the air quality of fresh air.At present, fresh air purify in VMC and mainly use HEPA filter screens
The method of purification, this fresh air purifying principle be by fresh air by the HEPA filter screens with huge adsorption area, it is micro- in fresh air
Grit is adsorbed by the huge adsorption area with tortuous air path in HEPA filter screens and reaches purification purpose, if necessary also
Some odor airs can be adsorbed along with charcoal absorption etc..These purification of air modes have simple structure, device fabrication
Low cost, the advantage of technology maturation, extensively using air purification field.But this purification of air mode exists certain
Problem.Be first filter screen air drag it is big, it is necessary to there is VMC larger blast can just drive air over HEPA filters
Net, not only increased the noise that energy consumption also increases blower fan, influence whether the daily lifes such as the rest of user；Meanwhile, this side
The purification of air of formula is that the micronic dust in air is transferred in filter screen, micronic dust accumulate on filter screen for a long time after often breed bacteria
Etc. secondary pollution is caused, IAQ is influenced whether on the contrary；3rd, the HEPA filter screens of this dependence adsorption cleaning air,
Its absorption micronic dust has certain adsorption capacity limit, is accomplished by changing when the adsorption capacity limit is reached, and this at present
Costly, therefore long-term use cost is higher for the price of HEPA filter screens.
Therefore, this HEPA filter screen types purification of air is not a kind of optimal method, not only long-term use high cost,
And secondary air pollution has been also tended to, the healthy of people is damaged on the contrary.
Except HEPA filter screen methods, purification of air there is a method in which, be exactly plasma electrostatic depuration, it is using opposite electricity
The attracting principle of lotus, makes the micronic dust in air powered using plasma electrostatic field, then the side adsorbed by the pole plate of oppositely charged
Formula carries out purification of air, and, this purification method is removed by the micronic dust in air with the larger molecular organicses purification for having peculiar smell
While going, the high voltage electric field that it is formed also has the effect killed to the bacterial virus in air, so as to have avoid accumulation
Micronic dust breed bacteria cause the effect of secondary air pollution.Current this purification of air mode is not already main product, but by
In its long-term use low cost, while also there is certain sterilizing to act on, relative to HEPA filter net type air purifiers
With wider market potential.The present invention is exactly that this air purifying process is transplanted in VMC, and by solving
Purification of air is carried out to fresh air on the basis of a series of problems that the technology exists in actual applications, so as to form a kind of process
The health-oriented products of purification of air.
Meanwhile, although the heat exchange type for using at present function of the new blower fan with energy-conservation, one side energy regenerating is limited
, on the other hand also there are problems in turn in (in fact less than 50%).
Firstly, since needs swap room air resorption and fresh air, even if it is net to have carried out air to fresh air pipeline
Change, typically the air of resorption especially can not possibly just be purified since resorption mouthful, therefore in the air-flow warp of resorption
The part such as pipeline, air port for crossing can constantly gather micronic dust, and the harmful and noxious substance such as breed bacteria, and these harmful and noxious substances exist
These bacteriums can be taken in fresh air to the secondary pollution for causing fresh air after being exchanged with fresh air, especially hand over the accumulation of film surface in full heat
The harmful substance such as bacterium grown of micronic dust can enter directly into fresh air, its harm is bigger.
Secondly, the new blower fan of heat exchange after long-term use, can cause to pass in and out the imbalance of air quantity, because in order to ensure air intake
Quality, it will usually fly net or coarse strainer be installed in air inlet, the time one is grown after these fly nets or coarse strainer be blocked, air intake
Amount will be reduced, and when intake is less than resorption air quantity, negative pressure will be formed in room, and the outdoor air without by purification is just
Can be entered into room by crack between a door and its frame, window seam etc., the quality of fresh air will be greatly reduced, or even lose the meaning of fresh air purifying
Justice, while the efficiency of recuperation of heat can also be reduced.
If the fresh air to unidirectional new blower fan is purified, because the micronic dust in the fresh air air by purification is basic
Eliminate, therefore just solve the problems, such as the laying dust of airflow line, even so that during long-term use, New atmosphere quality is also obtained
It is effective to ensure.
Therefore, for domestic consumer, although the unidirectional fresh air of purification type can be higher than the new blower fan of heat exchange on energy consumption,
But the air quality of fresh air can more be guaranteed, especially, the unidirectional new blower fan of purification type have passed through purification due to the fresh air for entering,
It is big to improvement in the distinguished and admirable laying dust phenomenon by position such as pipeline, particular without being easiest to cause laying dust and crossing air dirty
The heat exchange membranes of dye, the quality of fresh air can be obtained by effective guarantee.Meanwhile, plasma air purification function is in purification of air
While it is actual also there is the function sterilized to air high voltage electric field, the quality of air is further ensured, therefore make
It is that a more satisfactory healthy fresh air solves technical scheme with plasma cleaning unidirectional new blower fan.
But plasma static purification method is applied into unidirectional new blower fan to be also required to solve a series of problem.First
It is the problem of the purifying rate of plasma electrostatic depuration, because if plasma electrostatic depuration is inefficient, by after purification
Certain micronic dust is also carried in air, these microfarads are by accumulation for many years or secondary pollution can be caused to fresh air, and mesh
Preceding in the market can only achieve using the electrostatic air cleaning micronic dust purifying rate of the plasma of routine techniquesIt is such net
Change efficiency will not laying dust in still cannot ensureing the airflow line of long-term use for many years.Meanwhile, conventional plasma air purification
Escaping gas of the dust collecting electrode surface after laying dust escapes the air secondary for causing during device does not solve use still at present
Pollution problem, and there is the ozone generation problem that polarity of electrode reversion is caused by the plasma that dust collecting electrode surface laying dust causes,
Conventional plasma air purification product is that plasma generating assembly is integrated with dust collecting electrode at present, the device of this integration
Although compact but also more complicated, it is unfavorable for not exclusively with the daily dimension with operative knowledge, the domestic consumer of technical ability
Shield maintenance, the presence of these problems has had a strong impact on the application in daily life of plasma static purification, has added
Compare production cost high, make plasma electrostatic depuration compared with being purified with HEPA filter screens without prominent advantage.
The content of the invention
The technical problems to be solved by the invention be purification efficiency it is higher, while the unidirectional plasma of breed bacteria can be prevented

Wind chamber 10, as shown in Figure 1.Bypass airduct may be mounted at the back of air-inlet cavity or air-out chamber by wall, it is also possible to installed in air intake
Chamber or the both sides of air-out chamber, then be connected to outside wall.When bypass airduct is located at air-out chamber, set respectively on air outlet 6 and bypass airduct 3
Check-valves 61 and check-valves 31 are equipped with, when bypass airduct 3 is arranged on air-inlet cavity, air outlet 6 does not set non-return with bypass airduct 3
Valve.
Main air blower uses super quiet unidirectional blower fan, is divided into third gear above wind speed；There is PM2.5 to detect before and after air inlet, according to preceding
PM2.5 value differences and fresh air flow accumulation data afterwards, point out clearance time --- and from orifice plate cleaning, that battery lead plate is cleaned to coarse strainer is clear
Reason.
In control, can be using purification redundant fashion：The time that for example normal need is used is 12 hours, then can lead to
Subscription time control is crossed at 14 hours or so, that is, the use of previous hour is being to open, to increase using effect, and be not required to
One hour is opened again further to update the air in room after use, start in a hour in advance therein can not only be strengthened to be made
With impression, can more there is the time to carry out odor air exclusion.
Bypass airduct 3 is connected to outside building wall, main frame 1 is placed in indoor or outdoors and fixedly mounts, in new blower fan just
Often before operation purify air, first the escaping gas in the casing 4 of new blower fan is discharged, specific method is：Opening main air blower 7
Before, the bypass blower fan 2 of bypass airduct 3 is first opened, in the case where bypass airduct is located at air-out chamber, on air outlet and bypass airduct

To prevent mosquito and bulky grain dirt in air to be inhaled into；
Bypass blower fan 2 and bypass airduct 3 have two kinds of installation methods：One kind is arranged on air-inlet cavity 9, that is, installed in corona
Before generation pole 811, check-valves need not be installed in air outlet and bypass airduct during odor air in exclusion machine of starting shooting；It is another
Plant and be arranged on after air-out chamber, that is, the porous collecting plate 82 in separate type section, needed during odor air in exclusion machine of starting shooting
By closure of check ring air outlet 6.
As shown in figure 3, plasma electrostatic depuration component 8 includes that plasma electrostatic generating assembly 81 and separate type section are porous
Collecting plate 82, the porous collecting plate 82 in separate type section is located at the rear side of plasma electrostatic generating assembly 81.
Plasma electrostatic generating assembly 81 includes multipair by corona generation pole 811 and to the alternating parallel of battery lead plate (rod) 812
Two pieces are located at there is pole 811 between battery lead plate (rod) 812, two pieces between battery lead plate (rod) 812 in the electrode pair of distribution, corona
It is inlet channel 83, inlet channel 83 is perpendicular to the porous collecting plate 82 in separate type section.Battery lead plate (rod) 812 and separate type are cut
The porous collecting plate common ground in face is improving the security that equipment is used.
Corona is placed in battery lead plate (rod) 812 after there is pole 811.The porous collecting plate 82 in separate type section is porous hardened
Structure, including foam metal plate and other foam conductive materials, metal or porous, electrically conductive tabular material etc. other conductive material screen clothes
Expect, for example porous nickel mesh, stainless (steel) wire etc..
The porous collecting plate 82 in separate type section be located at body interior air-flow section on, can in airflow direction cloth
Put, it is also possible to form certain angle with air-flow with increase with the contact area of air-flow, further improve purification efficiency.
The porous collecting plate 82 (loose structure) in separate type section solves the problems, such as purification efficiency, and when solving using one section
Between, form reverse corona after the accumulation of collecting plate surface dust problem occur to the ozone that causes, and enormously simplify dust collecting electrode
Cleaning；
Bypass blower fan structure solves the problems, such as the secondary pollution of escaping gas.
The porous collecting plate 82 in separate type section, refers in particular to have tortuous aperture and foam gold of the aperture less than 1 millimeter
Category plate material (porous nickel mesh, foam copper) is used as the porous dust collecting electrode in section, and purification efficiency is greatly improved.
The material of the porous collecting plate 82 in separate type section is foam metal plate or wire netting.
The porous collecting plate 82 in separate type section is made up of one layer and more than one layer of foam metal plate or wire netting, one layer with
On foam metal plate or wire netting can be mounted side by side with integrator, or separate, tandem.More than one layer point
From formula section, porous collecting plate 82 is generally divided into two pieces of tandem, before one piece be stainless (steel) wire, below one piece be nickel foam
Plate plate, such pollutant is main first to be adsorbed by stainless (steel) wire above, and stainless (steel) wire is easier to clear up relatively, and a small amount of residue does not have
There is adsorbed micronic dust to be adsorbed by the much better porous nickel mesh plate of adsorption effect again, so can not only reach fabulous purification
Effect, also extends the clearance time interval of the relative complex porous nickel mesh plate of cleaning.
Corona generation pole 811 is rearmounted to be considerably reduced to the surface laying dust ash speed of battery lead plate 812, significantly extends electricity
The dizzy cleaning service time that electrode assemblie occurs is spaced, reduces ozone generation：Using corona wire layout on rear side of to battery lead plate,
There is the rearmounted method in pole 811 to solve to the surface dirt ash accumulation problems of battery lead plate 812 in corona.
Normal electrostatic occur electrode lay-out using corona occur pole 811 be located to before and after battery lead plate 812 along centre,
So air enter electrostatic field, micronic dust it is powered after, micronic dust will be moved in the presence of stationary electrode to battery lead plate 812, and part is micro-
Dirt will be accumulated in the surface of battery lead plate 812, particularly to the rear portion of battery lead plate 812, so as to cause to the laying dust of battery lead plate 812 ash.
To the surface laying dust class of battery lead plate 812 except causing to need battery lead plate 812 often cleaning, and scale removal process is easily damaged electrode,
Because causing the deformation and displacement of the electrode with strict pitch requirements, meanwhile, being also easy to greatly to battery lead plate 812 after laying dust ash
Amplitude increases the generating capacity of ozone.
There is pole 811 (corona wire) layout to the rear portion of battery lead plate 812 in corona, plasma electrostatic field is mainly distributed on to electricity
The rear portion of pole plate 812, powered micronic dust is adsorbed to the possibility above battery lead plate 812 when being travelled forward under the drive of air-flow
Property be just greatly lowered, so as to solve the problems, such as to the laying dust of battery lead plate 812 ash, significantly extend the time interval of cleaning.
In order to solve corona occur electrode 811 it is rearmounted after influence to the trailing edge article on plasma electrostatic field of battery lead plate 812, it is right
Battery lead plate 812 can be using the conductiving metal strip of certain diameter or conductive metal pipe (such as diameterStainless steel or aluminium close
Gold bar or pipe), corona wire is arranged in the middle of the seam on rear side of these parallel conductiving metal strips or conductive metal pipe.Such as Fig. 3 and
Fig. 4, is to be placed in battery lead plate 812 or the schematic diagram to electrode bar after corona occurs electrode.Can be tabular, pole shape to electrode
Or circular tube shaped, to electrode there is the diameter of pole with diameter greater than corona in pole shape or circular tube shaped.
