Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Refer to a kind of structural representation Fig. 1 of the present invention, embodiment one, this multilayer electrostatic air filtration plate, be made up of five pieces of parallel collecting plates, collecting plate is made up of metallic plate and insulation electret together with it, adjacent two pieces of collecting plate institute receiving electrode polarity are contrary, and every block collecting plate has many places circular filter air duct, this filtered air channel vertical is in the collecting plate at its place.In the present embodiment, five pieces of parallel collecting plates are all wrapped in by insulation electret; Connected by insulation electret between parallel collecting plate, this connection is all filled by insulation electret between collecting plate to realize, seem more clear to make structure, all be not included in by metallic plate 2 in insulation electret 3 at outer ledge place in this accompanying drawing, in figure, filtered air passage 4 is circular.Can better embody the arrangement of metallic plate 2 in fig 2, metallic plate have filtered air passage 4, five pieces of metallic plates arranged in parallel, can form four layers of electrostatic field after energising, clean-up effect certainly can be well a lot of than single one deck electrostatic field.It is to strengthen adsorption effect that metallic plate is combined with insulation electret, can also continue after a loss of power to keep a period of time electrostatic field, more can save the energy; The metallic plate electret that insulated is wrapped in and is not easy external electric discharge, safer, is not easy to produce ozone.
As shown in Fig. 3, Fig. 4, Fig. 5, the filtered air passage 4 on collecting plate 1 can have various shape, and in Fig. 3, air duct 4 great majority are quadrangles; In Fig. 4, air duct 4 is square and rectangular combination; In Fig. 5, air duct is circular and rectangular combination.Found through experiments filtered air passage for good filtration effect when circular, oval, trapezoidal, parallelogram or regular polygon, and the most important thing is easy cleaning, its dust adsorbed above is easy to be washed by water.If wherein filtered air passage is circular and wherein 3 millimeters to 5 centimetres the bests; If filtered air passage is extraordinary selection for being that its width of square or rectangular is more than or equal to 5 millimeters, is less than or equal to 3 centimetres; Other shapes can be implemented with reference to above-mentioned mark.
As shown in Figure 2, wherein metallic plate 2 can wrap up one deck thin insulating electret above, and its shape is still with similar shown in Fig. 2; Then be fixed on a collecting plate bracing frame.Air filter plate shown in Fig. 1 is because be that one-shot forming does not just need collecting plate bracing frame, and also having in embodiment below to need collecting plate bracing frame.
As shown in Figure 6, can have raised support point 5 on 1, can separate two pieces of collecting plates like this on collecting plate, the metallic plate 2 on collecting plate all UNICOM forms electrostatic field between upper and lower two pieces of collecting plates after high voltage source.Although such mode can not need collecting plate bracing frame, there will be the situation of easily dislocation between upper and lower collecting plate, below how description is addressed this problem.Air duct between upper and lower collecting plate can through place mutually corresponding, also can be straggly opening, by practice find the effect held straggly can be better.
As shown in Figure 7, collecting plate 1 has two raised support points 5 and two depression locating slots 6 above, the another side at each strong point 5 place place on collecting plate 1 one faces is that the strong point 5 in depression locating slot 6, face at least matches with a locating slot caved in 6 of another side.The height of the strong point 5 can be identical with the degree of depth of locating slot 6 or be less than the degree of depth of locating slot, if the combined effect of multiple like this collecting plate is just close with the rate of air filtration shown in Fig. 1 plate.If but strong point height be greater than the depth localization groove of locating slot 6 the degree of depth that just have diverse technique effect, gap is had between adjacent two pieces of collecting plates, because air is by the filtered air passage perpendicular to collecting plate, gap between collecting plate is perpendicular to filtered air passage, at air in filtration channel, the granule foreign had in air is adsorbed, and has gap will strengthen the ability holding absorbate between adjacent two pieces of collecting plates.One-time formed air filter plate also can leave gap between two pieces of collecting plates, cleans if position arranges bad may being not easy, and can consider between two pieces of collecting plates, do a more shallow little groove.As shown in Figure 9, it is a kind of electrostatic air filtration plate cross-sectional view that the collecting plate in Fig. 7 is combined into.
As shown in Figure 8, the described strong point 5 number is two, and each strong point is electrically connected with the locating slot 6 of its corresponding position on same collecting plate, and wherein the strong point on the right is also electrically connected with the metallic plate 2 on its place collecting plate; UNICOM's conductor is formed both the described strong point 5 collecting plate identical with another mates when locating slot 6 combines.Collecting plate in Fig. 8 be combined with each other form electrostatic air filtration plate, it finally only has two strong points externally to form positive and negative electrode junction, if namely combined according to the collecting plate arrangement mode shown in Fig. 9, two strong points 5 are finally only had externally to form positive and negative electrode junction.
A kind of multilayer electrostatic air filtration plate of the present invention is for being arranged on air cleaning unit, generally be connected on the dc source of high pressure, polarizing voltage is just very good at about the 8 kilovolts electrostatic field clean-up effects formed, when applying, air can first by the electrostatic air filtration plate through hyperpolarization after thicker screen pack, and then just can complete the purification to air once through activated carbon filtration, the polarization of insulation electret the interior maintenance of certain hour can have adsorptivity after a loss of power, the present invention is simple, noise is low, energy-conservation, and good filtration effect, be easy to cleaning.
These are only better case study on implementation of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
