Detailed description of the invention
Below in conjunction with being embodied as case, the present invention is expanded on further.Should be understood that these case study on implementation are merely to illustrate the present invention rather than restriction the scope of the present invention.In addition, it is to be understood that after having read present disclosure, the present invention can be made various changes or modifications by those skilled in the art, these equivalent form of values fall within the scope that the application institute appended claims limits equally.
Case study on implementation 1
As it is shown in figure 1, air purifier 101 includes one group of line corona, and pole occurs, the cross-sectional view shown in Fig. 1 denotes two coronas pole 102 occurs.Corona occurs pole to be positioned in the first plane 103.
Air purifier 101 also comprises a series of collector.The cross-sectional view of Fig. 1 shows 3 groups of collectors: 104,105 and 106.Each group of collector comprises the collector (also referred to as collecting split pole) of some (no less than 2, such as any amount such as 2,3,4), shows 5 independent collectors (collection classification) in FIG.These electrodes are shown conglobate cross section in FIG, but actually they can be the outward appearance of any shape, as long as conductive hollow tubing.Collecting split pole cross sectional dimensions D5 is 5mm, and corona occurs pole cross sectional dimensions D9 to be 0.15mm.
Each collection split pole and the first plane 103 are completely vertical, to promote that air occurs pole 102 to flow to collector 104,105 and 106 from corona, are from left to right in FIG.Often group collection split pole all has a limit 107 nearest from the first plane 103, and these distance coronas occur the limit of extremely nearest collector be arranged in the second plane 108(or determine the second plane with their axis).
Distance D4 between first plane 103 and the second plane 108 is 50mm, and often the distance D2 between group collector adjacent part is 18mm.It is a variable arbitrary value with the distance D3 between group adjacent collector split pole, but is not preferably greater than 18mm.In the present embodiment, the collector of same group distance each other is laterally away from corona from close corona generation pole one and occurs side, pole progressively to reduce, if the distance D3 between first collector and second collector is 18mm, distance between second to the 3rd is 15mm, distance between 3rd to the 4th is 12mm, distance D3 ' between 4th to the 5th is 9mm, such arrangement, make while increasing collector surface area, reduce collector and the volume of the distance between pole and whole collector occurs to corona, clean-up effect also gets a promotion..
Repel split pole and be equidistantly distributed between collection split pole, also with corona, pole keeping parallelism occurs so that between repeller and collector, form the high field of same intensity simultaneously.One group of repeller comprises the repulsion split pole of some (no less than two, such as any amount such as two, three, four, five), is shown as 4 in FIG and repels split poles.The cross sectional dimensions of repulsion split pole reaches optimal running effect time equal with the cross sectional dimensions collecting split pole, therefore the size repelling split pole is 5mm equally.
Equally, it is also all equidistant for collecting between split pole and the repulsion split pole being adjacent, so, D7 and D8 is identical.
Each corona occurs the mutual distance D1 between pole to be variable and do not affect electrostatic air cleaner clean-up effect.Corona occurs the quantity of pole should be collector quantity ± 1.When ensureing field intensity, corona occurs the quantity of pole also can reduce half.Experiments show that, the maximum of corona generation number of poles not should be greater than collector quantitative value and adds one, minima cannot be less than collector quantitative value two/subtract 1 again and again.As in the present embodiment, corona occur pole quantity be collect split pole two/subtract one again and again, namely collect split pole be 5, corona occur pole quantity be 2.On space length, corona occurs pole distance D1 to be each other 25mm, and it is not less than the distance D2 often organizing between adjacent collector pole and is not more than again 2 times of D2 simultaneously.
For preventing the electric discharge phenomena between collector and repeller end, they are all spaced from each other with insulation barrier.As in figure 2 it is shown, collector 202 and repeller 203 interphase distribution in turn, the end of these electrodes is carried out electric protection by insulation barrier 204, and these insulation barriers 204 are supported by insulation board 205, so make all of electrode all keep apart with insulation barrier.Each electrode separates again separated region 206 with insulation barrier, makes electric field intensity more uniformly and prevent the sparking between electrode end.
On the basis of the present embodiment, also has scheme two kinds different, the first, the collector of same group distance each other is laterally away from corona from close corona generation pole one and occurs side, pole to be stepped up, if the distance D3 between first collector and second collector is 6mm, distance between second to the 3rd is 10mm, and the distance between the 3rd to the 4th is 14mm, and the distance D3 ' between the 4th to the 5th is 18mm.It two be above-mentioned all of distance value is all identical, as being 8mm.
Embodiment 2
As it is shown in figure 1, air purifier 101 includes one group of line corona, and pole occurs, the cross-sectional view shown in Fig. 1 denotes two coronas pole 102 occurs.Corona occurs pole to be positioned in the first plane 103.
Air purifier 101 also comprises a series of collector.The cross-sectional view of Fig. 1 shows 3 groups of collectors: 104,105 and 106.Each group of collector comprises a number of collection split pole, shows 5 independent collection classifications in FIG.These electrodes are shown conglobate cross section in FIG, but actually they can be the outward appearance of any character.Collecting split pole cross sectional dimensions D5 is 3mm, and corona occurs pole cross sectional dimensions D9 to be 0.05mm.
Each collection split pole and the first plane 103 are completely vertical, to promote that air occurs pole 102 to flow to collector 104,105 and 106 from corona, are from left to right in FIG.Each collection split pole has a limit 107 nearest from the first plane 103, and these distance coronas occur the limit of extremely nearest collector to be arranged in the second plane 108.
Distance D4 between first plane 103 and the second plane 108 is 50mm, and often the distance D2 between group collector adjacent part is 17mm.Distance between adjacent collector split pole is a variable value, but is not preferably greater than 18mm.It is described later in detail in embodiment 1.
Repel split pole and be equidistantly distributed between collection split pole, also with corona, pole keeping parallelism occurs so that between repeller and collector, form the high field of same intensity simultaneously.One group of repeller comprises a number of repulsion split pole, is shown as 4 in FIG and repels split pole.The cross sectional dimensions of repulsion split pole reaches optimal running effect time equal with the cross sectional dimensions collecting split pole, therefore the size repelling split pole is 3mm equally.
Equally, it is also all equidistant for collecting between split pole and the repulsion split pole being adjacent, so, the distance of D7 and D8 is identical.
Each corona occurs the mutual distance D1 between pole to be variable and do not affect electrostatic air cleaner clean-up effect.Corona occurs the quantity of pole should be collector quantity ± 1.When ensureing field intensity, corona occurs the quantity of pole also can reduce half.Experiments show that, the maximum of corona generation number of poles cannot be greater than collector quantitative value and adds one, minima cannot be less than collector quantitative value two/subtract 1 again and again.As in the present embodiment, corona occur pole quantity be collect split pole two/subtract one again and again, namely collect split pole be 5, corona occur pole quantity be 2.On space length, corona occurs pole distance D1 to be each other 26mm, and it is not less than the distance D2 often organizing between adjacent collector pole and is not more than again 2 times of D2 simultaneously.
For preventing the electric discharge phenomena between collector and repeller end, they are all spaced from each other with insulation barrier.As in figure 2 it is shown, collector 202 and repeller 203 interphase distribution in turn, the end of these electrodes is carried out electric protection by insulation barrier 204, and these insulation barriers 204 are supported by insulation board 205, so make all of electrode all keep apart with insulation barrier.Each electrode separates again separated region 206 with insulation barrier, makes electric field intensity more uniformly and prevent the sparking between electrode end.
Embodiment 3
It is another embodiment of the invention as shown in Figure 3.Other parts are all identical with embodiment 1 or embodiment 2, simply in the present embodiment, collector and repeller are all thus forming the continuous conduction pipe that is parallel to each other in edge's bending, this electrode part is to accelerate to fly to collector as the dust granule forced between two panels collector, it is prevented that it is escaped from centre.Such design, makes electrode production can take into account the clean-up effect of production cost and air purifier better.
Embodiment 4
All the other are identical with embodiment 3, are different in that, collecting split pole cross sectional dimensions D5 is 4mm, and corona occurs pole cross sectional dimensions D9 to be 0.1mm.
Distance D4 between first plane 103 and the second plane 108 is 52mm, and often the distance D2 between group collector adjacent part is 17.5mm.Distance D3 to D ' 3 between adjacent collector split pole is a variable value, but is not preferably greater than 18mm.
The cross sectional dimensions of repulsion split pole reaches optimal running effect time equal with the cross sectional dimensions collecting split pole, therefore the size repelling split pole is 4mm equally.Certainly, repel split pole size adopt as 3mm, 5mm can also, be effect slightly worse.
Embodiment 5
The 4th kind of embodiment such as Fig. 4 of the present invention a) shown in.There is pole containing a series of line coronas similar with shown in Fig. 1 in the air purifier 401 in this kind of embodiment, these coronas occur pole 402 to be positioned on first surface 403.Collector and corona occur pole to be spatially separated from each other.Each group of collector 404,405 and 406 comprises several collection split pole.Collector has respective edge, and these edges are positioned on the second curved surface 407.First surface 403 and the second curved surface 407 are equidistant between its respective points, all adopt optimum value 50mm with distance 415(the present embodiment, it is also possible to adopt other numerical value such as 30mm, 40mm, 60mm as required) spaced apart.Moreover there is pole and be equidistant from the distance between its nearest collector edge in each corona.Because air radially flows, collector is then along the directional spreding of air flowing.
Embodiment 6
The b of the 5th kind of embodiment such as Fig. 4 of the present invention) shown in.Air purifier 408 only has a line corona and pole 414 and several (its quantity is the Arbitrary Digit more than 2) collector occurs, and is shown as three: 409,410 and 411 in Fig. 4 b).Each collector contains several collection split pole (its quantity is the Arbitrary Digit be more than or equal to 1), is shown as four in Fig. 4 b).Collector has respective edge and these edges and is positioned on flexure plane 412.Due to air-flow direction radially, collector should be positioned on the circuit of the radial flowing of air, and it with corona, the spacing equal (416=417) of pole 414 occurs.
The invention has the beneficial effects as follows, collector and repeller are made up of independent split pole, and these electrodes are made up of conductive hollow pipe, and the geometry designs of this electrode considerably reduces its weight and cost.
The first plane and the second plane described in above-described embodiment are parallel to each other, can also as shown in Fig. 4 a), it it is both curved surface, it is first surface 403 and the second curved surface 407, any point on described second curved surface 407 is all equal with the distance of closest approach on first surface 403, so can more reasonably arrange according to product design each electrode, reach optimize profile and reduce the purpose of volume.
At this, above-described embodiment being described further, in a kind of form of the present invention, each collection split pole and the first plane 103 are completely vertical, to promote that air occurs pole 102 to flow to collector 104,105 and 106 from corona.Each collection split pole has a limit nearest from the first plane 103, for instance the limit 107 in Fig. 1.These distance coronas occur the extremely nearest limit Common arrangements collecting split pole in the second plane 108.
Distance D4 between first plane 103 and the second plane 108, there is the distance D1 between pole in neighboring corona, often the distance between group adjacent collector pole is D2.One electrostatic air cleaner is it suffices that require as follows: it should provide high filtration performance, as far as possible the dust in absorbed air, and should not produce unnecessary ozone, for instance, according to the 37th of UL867 standard the article, in a certain special space, it is not more than 50ppb.It is known that the generation of ozone is proportional to corona current and voltage or power with corona discharge is unrelated.For example, it is assumed that in certain electrostatic air cleaner, D4 is 20mm, corona current is 1mA, and corona occurs the electric potential difference between pole 102 and collector (104,105 and 106) to be 15kV, and ozone production rate is 10mkg per hour.If increasing D4 to 40mm and making corona occur the electric potential difference between pole and collector to become 30kV, some corona current is about 0.5mA, then ozone generation rate is about 5mkg per hour.
It is then clear that from acceptable ozone emission rate angle, the value of D4 is the bigger the better.Distance D2 between collector should be little of as far as possible to ensure good dust adsorption rate simultaneously.When charged grit enters the region between collector and repeller, grit is collected pole under the effect of high field and adsorb and be ostracised pole repulsion.If the value of D2 is too big, charged grit arrives the probability on collector surface and is just lowered, and therefore D2 should be sufficiently small to ensure good grit adsorption effect.But meanwhile, distance D2 can not be too little, otherwise collector will block air flowing.
Distance D3 between each collection split pole adjacent part also has very important effect in the performance of electrostatic air cleaner.If distance D3 becomes little, filtering dust effect will be better, because now the surface area of collector will tend to maximum.But meanwhile, the weight of collector and cost will increase therewith.Through repetition test, it has been found that the value of D3 not should be greater than D2, to ensure to reach optimum balance between high filtration capacity and acceptable electrode cost and depurator weight.
The value of D3 is to change with the length of collector and change, for instance the D3 in Fig. 1 is not equal to D ' 3.In most cases, change the value of D3 and can adjust the overall dimension of depurator and cost provides acceptable grit filter effect simultaneously.
The electrostatic air cleaner of the present invention further comprises repeller, and these repellers are equally spaced between collector so that forms high field between collector and repeller.Repeller also occurs extremely parallel with corona.Repeller can be any geometry, such as: flat metal plate, with bossed metallic plate, the metallic plate of bending and metallic plate etc. in a zigzag.The advantage of repeller is in that it is light and handy and with low cost.
Each repels split pole should be positioned at the adjacent centre collecting split pole, so makes electric field intensity keep consistent.The cross sectional dimensions D6 of each repulsion split pole and collection split pole cross sectional dimensions D5 can reach optimized operation effect time equal, so can ensure that around collector identical with the electric field intensity of repeller each several part, so that reaching maximum potential difference between collector and repeller.
It is also important that each collection split pole and each distance repelled between split pole being adjacent should be equal, namely each collection split pole and the repel split pole adjacent with it are equidistant, namely a No. 1 distance D7 repelled between split pole collecting split pole and its side should be equal to the distance D8 between this collection split pole and No. 2 repulsion split poles on its side, and so on.This should remain the same from beginning to end in the assembling of electrode.
Each corona occurs the mutual distance D1 between pole to be variable and do not affect electrostatic air cleaner clean-up effect.Corona occurs the quantity of pole should be collector quantity ± 1.When ensureing field intensity, corona occurs the quantity of pole also can reduce half.Experiments show that, the maximum of corona generation number of poles cannot be greater than collector quantitative value and adds one, minima cannot be less than collector quantitative value two/subtract 1 again and again.For example, it is assumed that electrostatic air cleaner has 20 collectors, then corona occurs the maximum of pole to be 21, and minima is 9=20/2-1.On space length, D1 should be not less than D2 and be not more than 2 times of D2.
In sum, preferably ranging from of each parameter, the cross sectional dimensions D5 of described collector is 3mm-5mm, and described corona occurs pole cross sectional dimensions D9 to be 0.05mm-0.15mm.Distance D4 between described first plane and the second plane is 50mm-55mm, and described collector second distance D2 each other is 17mm-18mm.
In the electrostatic air cleaner of the present invention unique place's electric field intensity inconsistent region be positioned at each collection split pole and repel split pole end, these ends are close to each other and generally all have tip.For preventing the electric discharge phenomena between these ends, they should be spaced from each other with insulation barrier.Such as Fig. 2, from air outlet angle, collector 202 and repeller 203 interphase distribution in turn.The end of these electrodes is carried out electric protection by insulation barrier 204, and insulation barrier 204 is supported by insulation board 205.This design has important effect, and it makes all of electrode all keep apart with insulation barrier.Each electrode should have a separated region 206 with insulation barrier, and this separated region makes electric field intensity more uniformly and prevent the sparking between electrode end.
The electrode of the present invention can also have another kind of form, and as shown in Figure 3, electrode 301 is made up of a continuous print electric conductor (such as metal tube), and this continuous conduction material bends thus forming the part being parallel to each other in edge.This design makes can take into account more easily in electrode production the clean-up effect of production cost and electrostatic air cleaner.Collector or repeller all can make the geometry as shown in electrode 301.
Fig. 4 a) in show the another kind of improved procedure to the present invention.There is pole containing a series of line coronas similar with shown in Fig. 1 in electrostatic air cleaner 401, these coronas occur pole 402 to be positioned on first surface 403.Collector and corona occur pole to be spatially separated from each other.Each group of collector 404,405 and 406 comprises at least one and collects split pole.Collector has respective edge, and these edges are positioned on the second curved surface 407.First surface 403 and the second curved surface 407 should be equidistant between its respective points, all with distance 415 spaced apart.Moreover there is pole and be equidistant from the distance between its nearest collector edge in each corona.Because air radially flows, collector is then along the directional spreding of air flowing.
Figure tetra-is b) cross-sectional view of electrostatic air cleaner example of another recommended technology.Electrostatic air cleaner 408 only has a line corona and pole 414 occurs and no less than 2 collectors, three in figure: 409,410 and 411.Collector has respective edge and these edges and is positioned on flexure plane 412.Due to air-flow direction radially, collector should be positioned on the circuit of the radial flowing of air, and it with corona, the spacing equal (416=417) of pole 414 occurs.
The invention has the beneficial effects as follows, the collector of the present invention and repeller are made up of independent split pole, and these electrodes are made up of conductive hollow pipe, and the geometry designs of this electrode considerably reduces its weight and cost.This geometry designs is very fine to the requirement of size, and between the size of electrode, cross section and parts, mutual alignment etc. all should be taken into consideration.The all of size of the present invention includes its ratio and is all determined by experimental result and verify.
It is more than the description to the embodiment of the present invention, by the described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or use the present invention.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
