Abstract

It is an air purifier using electrostatic collecting and depositing floating dusts. It is made of at least of two electrodes, with one side a dust collector opposite to the land and surrounding articles with certain positive electrical potential, the other side a negative ion generator, with electrostatic field between them, electric line of force pointing to the negative ion generator from the dust collector. Negative ion makes the floating dust having negative charges, having the flowing dust accumulating and depositing to the dust collector through the attraction of the electrostatic field.

Description

Electrostatic dust catcher

Technical field

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.

Background technology

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 PAJNQ401156 proposition 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.

Summary of the invention

The purpose of this invention is to provide a kind of device that can make floating dust concentrate precipitation.Neither there is shortcoming described above, is 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 specific embodiment

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.

In the device shown in Figure 1, dust collecting electrode A+ has bigger radius of curvature, is connected with anion generator A-by high-voltage DC power supply E.Positive source meets dust collecting electrode A+, and negative pole meets anion generator A-, represents 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.Point on the anion generator A-from the power line of electrode A+.

Charged corpuscle that anion generator sends out and airborne floating dust are combined into charging point, represent with D-among the figure, under the positive electric field attraction force acts, are 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+ and anion generator A-in various possible concrete devices, all be positioned in outstanding around the position of object, further guarantee the power line overwhelming majority drop on electrode A-on.So that in the effective range of this device, the floating dust orientation is deposited on the dust collecting electrode A+.

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.Here annular electrode A+ has higher positive potential for anion generator A-, and is placed on the same center of circle, and 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.
