Abstract
The invention provides a kind of electrostatic field that utilizes and make directed precipitation, the new equipment that purifies air concentrated of showy dust.This device has at least two electrodes to form.One of electrode be with respect to the earth and on every side object the dust collecting electrode of definite positive electric potential is arranged, another is the anion generator that can produce electronegative particulate.Exist electrostatic field between two electrodes, the direction of power line is pointed to anion generator by dust collecting electrode.Anion makes negative electrical charge on the airborne floating dust band, attracted by electrostatic field, directionally concentrates to be deposited on the dust collecting electrode.
Description
The present invention relates to a kind of electrostatic field that utilizes and make the directed precipitation of concentrating of floating dust, realize the new equipment that purifies air.
People have known the technology of utilizing air negative ion generator to purify air very early.For example the anion generator of international patent application PAJNQ 401156 propositions is intended to utilize anion to catch floating dust, purifies air.Yet this patent is not intended to make floating dust to concentrate and is deposited to the regulation occasion.The shortcoming of its structure is floating dust object around precipitate everywhere, polluting arbitrarily naturally.And easy to clean not.
The purpose of this invention is to provide a kind of device that can make floating dust concentrate precipitation.And do not have shortcoming described above, be convenient to clear up laying dust.
Invention is achieved in that it has at least two electrodes to form, and one of electrode is the anion generator A that can produce electronegative particulate
-Another electrode be with respect to the earth and on every side object have dust collecting electrode A than high normal potential
+Exist electrostatic field between two electrodes, electronegative particulate is subjected to the attraction of dust collecting electrode, passes space, the two poles of the earth and is deposited on the dust collecting electrode, and seldom fall on other object.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof:
Fig. 1 is that the electrostatic dust catcher that proposes according to the present invention specifically installs;
What Fig. 2 illustrated is another concrete device of the present invention;
What Fig. 3 illustrated is the further device with dust catcher of forming with the anion generator concentric ring electrode.
Shown in Figure 4 is the vertical view of Fig. 3.
More than dotted line among each figure represent the possible path of electronegative floating dust when the dust collecting electrode displacement.
Describe the details and the working condition of the concrete device that proposes according to the present invention in detail below in conjunction with accompanying drawing.
In the device shown in Figure 1, dust collecting electrode A
+Has bigger radius of curvature, by high-voltage DC power supply E and anion generator A
-Be connected.Positive source meets dust collecting electrode A
+, negative pole meets anion generator A
-, represent with G in the ground connection point diagram of power supply, make electrode A
+With respect to the earth and on every side object have higher positive potential.From electrode A
+The power line that sets out points to anion generator A
-On.
Charged corpuscle that anion generator sends out and airborne floating dust are combined into charging point, among the figure with D
-Expression under the positive electric field attraction force acts, is deposited on the dust collecting electrode, positive and negative charge takes place simultaneously neutralize mutually.The power consumption that takes place in the system is provided by power supply E, and said process is maintained, and floating dust constantly precipitates, and air promptly is cleaned.
Dust collecting electrode A
+With anion generator A
-In various possible concrete devices, all be positioned in the outstanding position of object on every side, guarantee that further the electric power overwhelming majority drops on electrode A
-On.So that in the effective range of this device, the floating dust orientation is deposited to dust collecting electrode A
+On.
Fig. 2 represents another concrete device among the present invention.In this case, floating dust from top to bottom moves, and is deposited on the dust collecting electrode that is positioned at the bottom.The advantage of Fig. 2 device is to suppress the diffusion that hoists of dirt source, bottom, also is easy to clear up laying dust.Its control of dust process is identical with other function and Fig. 1.
Fig. 3 illustrates that the present invention has the concrete device of an annular electrode.Annular electrode A here
+ 1With respect to anion generator A
-Have higher positive potential, and be placed on the same center of circle, its plane separation anion generator has certain distance.Annular electrode has improved gas current intensity.Part anion arrives annular extraction electrode and constitutes the loop.The electric energy that consumes becomes the kinetic energy of electric wind, and electric wind promotes the bigger floating dust particulate of quality, makes it to reach dust collecting electrode.
The major advantage of Fig. 3 device is to improve the gathering speed of floating dust, and helps the precipitation of bulky grain floating dust.
The control of dust process of Fig. 3 device is identical with Fig. 1.
The anion generator of being mentioned in the literary composition, the prior art that can adopt everybody to understand.Generate charged aerosol technology Japan Guan Yifu chief editor " static handbook and Japan " electric association technical report " (II portion) all did detailed argumentation for No. 56.
The application of the principle of this invention also is not limited to utilize anion, and this principle just can be used the ion of positively charged naturally.
