Embodiment 5
The 4th kind of embodiment of the present invention as Fig. 4 a) shown in.Air purifier 401 in this kind embodiment contains the similar line corona generation utmost point a series of and shown in Figure 1, and these corona generation utmost points 402 are positioned on the first surface 403.Collector and the corona generation utmost point spatially are separated from each other.Each group collector 404,405 and 406 comprises several collection split poles.Collector has edge separately, 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(present embodiment, also can adopt as required other numerical value such as 30mm, 40mm, 60mm) apart separate.Further be each corona generation utmost point and be equidistant apart from the distance between its nearest collector edge.Flow because air is radial, collector then distributes along the direction of Air Flow.
Embodiment 6
The 5th kind of embodiment of the present invention is such as the b of Fig. 4) shown in.Air purifier 408 only has a line corona generation utmost point 414 and several (its quantity for greater than 2 Arbitrary Digit) collector, Fig. 4 b) in be shown as three: 409,410 and 411.Each collector has comprised several collection split poles (its quantity for more than or equal to 1 Arbitrary Digit), Fig. 4 b) in be shown as four.Edge and these edges that collector has separately are positioned on the flexure plane 412.Because air-flow direction is radial, collector should be positioned on the radial mobile circuit of air, and its spacing with the corona generation utmost point 414 equates (416=417).
The invention has the beneficial effects as follows that collector and repeller are made of split pole independently, these electrodes are made by the conduction hollow pipe, and the geometry designs of kind electrode has greatly reduced its weight and cost.
Described the first plane of above-described embodiment and the second plane are parallel to each other, also can be such as Fig. 4 shown in a), it both is curved surface, be first surface 403 and the second curved surface 407, the distance of closest approach all equates on any point on described the second curved surface 407 and the first surface 403, can according to more rational each electrode of arranging of product design, reach the purpose of optimizing profile and reducing volume like this.
At this above-described embodiment is described further, in a kind of form of the present invention, it is fully vertical with the first plane 103 that each collects split pole, with promote air from the corona generation utmost point 102 to collector 104,105 and 106 mobile.Each is collected split pole and has nearest limit, a distance the first plane 103, for example limit among Fig. 1 107.These are arranged in the second plane 108 jointly apart from the limit that extremely nearest collection split pole occurs corona.
Distance B 4 between the first plane 103 and the second plane 108, the distance B 1 between the adjacent corona generation utmost point, the distance between every group of adjacent collector is D2.An electrostatic air cleaner should satisfy following requirement: it should provide the high filtration performance, the dust in the absorbed air as far as possible, and should not produce unnecessary ozone, and for example, according to the UL867 standard the 37th is not more than 50ppb in a certain special space.As everyone knows, the generation of ozone and corona current are proportional and irrelevant with voltage or the power of corona discharge.For example, suppose that D4 is 20mm in certain electrostatic air cleaner, corona current is 1mA, and the electrical potential difference between the corona generation utmost point 102 and the collector (104,105 and 106) is 15kV, and the ozone production rate is 10mkg per hour.If increase D4 to 40mm and make the electrical potential difference between the corona generation utmost point and the collector become 30kV, the some corona current is about 0.5mA, and then the ozone generating rate is about per hour 5mkg.
So obviously, from acceptable ozone emission rate angle, the value of D4 is the bigger the better.Distance B 2 between the collector should be as far as possible little of to guarantee good dust adsorption rate simultaneously.When charged grit enters zone between collector and the repeller, grit is collected utmost point absorption under the effect of high field and the utmost point of being ostracised repels.If the value of D2 is too large, the possibility that charged grit arrives the collector surface just is lowered, so D2 should be enough little of to guarantee good grit adsorption effect.But simultaneously, distance B 2 can not be too little, otherwise collector will be blocked Air Flow.
Each distance B 3 of collecting between the split pole adjacent part is also having very important effect aspect the performance of electrostatic air cleaner.If distance B 3 becomes little, the dust filter effect will be better, because the surface area of collector will tend to maximum at this moment.The weight of collector and cost will increase thereupon but simultaneously.Through repetition test, find that the value of D3 should be greater than D2, to guarantee reaching optimum balance between high filtration capacity and acceptable electrode cost and the clarifier weight.
The value of D3 is that the length variations with collector changes, and for example the D3 among Fig. 1 is not equal to D ' 3.In most cases, overall dimension and cost that the value that changes D3 can be adjusted clarifier provide acceptable grit filter effect simultaneously.
Electrostatic air cleaner of the present invention has also comprised repeller, and these repellers are equally spaced between collector, so that form high field between collector and the repeller.Repeller also occurs extremely parallel with corona.Repeller can be any geometry, such as: flat metal plate, with bossed metallic plate, crooked metallic plate and metallic plate etc. in a zigzag.The advantage of repeller is that it is light and handy and with low cost.
Each repels the centre that split pole should be positioned at adjacent collection split pole, like this so that electric-field intensity be consistent.Each cross sectional dimensions D6 that repels split pole can reach the optimized operation effect with collecting when split pole cross sectional dimensions D5 equates, it is identical with the electric-field intensity of repeller each several part to guarantee like this to center on collector, thereby makes the maximum potential difference that reaches between collector and the repeller.
It is also important that the distance of respectively repelling between the split pole of respectively collecting split pole and being adjacent should equate, be that each collects split pole and the repulsion split pole adjacent with it is equidistant, the distance B 7 of namely repelling between the split pole for No. 1 of a collection split pole and its next door should equal the distance B 8 between this collection split pole and No. 2 repulsion split poles by its, and by that analogy.This should remain the same from beginning to end in the assembling of electrode.
Mutual distance B 1 between each corona generation utmost point is variable and does not affect the electrostatic air cleaner clean-up effect.The quantity of the corona generation utmost point should be collector quantity ± 1.In the situation that guarantees field intensity, the quantity of the corona generation utmost point also can reduce half.Experiment shows that the maximum of corona generation number of poles must not add one greater than the collector quantitative value, and minimum of a value must not be less than two of collector quantitative value/subtract again and again 1.For example, suppose that electrostatic air cleaner has 20 collectors, then the maximum of the corona generation utmost point is 21, and minimum of a value 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, the preferable range of each parameter is, the cross sectional dimensions D5 of described collector is 3mm-5mm, and described corona generation utmost point cross sectional dimensions D9 is 0.05mm-0.15mm.Distance B 4 between described the first plane and the second plane is 50mm-55mm, and described collector second distance D2 each other is 17mm-18mm.
The inconsistent zone of unique place's electric-field intensity is positioned at the end of respectively collecting split pole and repelling split pole in the electrostatic air cleaner of the present invention, these terminal mutually near and usually all have a 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 the air outlet angle, collector 202 and repeller 203 be interphase distribution in turn.The end of these electrodes carries out electric protection by insulation barrier 204, and insulation barrier 204 is supported by insulation board 205.Thisly be designed with important effect, it all keeps apart all electrodes with insulation barrier.Each electrode should have a separated region 206 with insulation barrier, and this separated region makes electric-field intensity more evenly and prevents sparking between the electrode end.
Electrode of the present invention can also have another kind of form, and as shown in Figure 3, electrode 301 is made by a continuous electric conductor (for example metal tube), thereby this continuous conduction material is in the crooked part that is parallel to each other that forms of edge.This design makes the clean-up effect that can take into account more easily production cost and electrostatic air cleaner in the electrode production.Collector or repeller all can be made the geometry shown in electrode 301.
Fig. 4 a) in shown another kind of improved procedure of the present invention.Electrostatic air cleaner 401 contains the similar line corona generation utmost point a series of and shown in Figure 1, and these corona generation utmost points 402 are positioned on the first surface 403.Collector and the corona generation utmost point spatially are separated from each other.Each group collector 404,405 and 406 comprises at least one and collects split pole.Collector has edge separately, 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 apart separate with distance 415.Further be each corona generation utmost point and be equidistant apart from the distance between its nearest collector edge.Flow because air is radial, collector then distributes along the direction of Air Flow.
Fig. 4 b) is the cross-sectional view of the electrostatic air cleaner example of another recommended technology.Electrostatic air cleaner 408 only has a line corona generation utmost point 414 and is no less than 2 collectors, such as three among the figure: 409,410 and 411.Edge and these edges that collector has separately are positioned on the flexure plane 412.Because air-flow direction is radial, collector should be positioned on the radial mobile circuit of air, and its spacing with the corona generation utmost point 414 equates (416=417).
The invention has the beneficial effects as follows that collector of the present invention and repeller are made of split pole independently, these electrodes are made by the conduction hollow pipe, and the geometry designs of kind electrode has greatly reduced its weight and cost.This geometry designs is very meticulous to the requirement of size, and mutual alignment etc. all should be listed consideration between the size of electrode, cross section and the parts.The all sizes of the present invention comprise that its ratio is all determined and checking by experimental result.
