Embodiment 1

[0038] figure 2 It is a structural schematic diagram of the present invention (using comb-shaped electrodes, two-phase AC drive power supply); a pair of comb-shaped electrodes are in the same plane, and the first comb-shaped teeth 1 and the first comb-shaped teeth 2 of the pair of electrodes are opposite Placed crosswise, the cross-section width of the comb-shaped teeth is 0.1mm-1.5mm, and the spacing between the comb-shaped teeth is 0.2mm-5mm; an AC voltage of 50V-2000V (ie, the driving power V) is connected to the input end of the electrode, and the The AC voltage is a square-wave AC power source with an adjustable frequency between 50 and 500 Hz. The parallel electrodes of the planar dust removal device of this embodiment can be placed on a substrate.

Embodiment 2

[0040] attached image 3 It is a schematic diagram of the structure of the present invention (using a spiral-shaped electrode, two-phase alternating current driving power supply); the driving power adopts two-phase electric driving, and after passing through the alternating current, the dust will be removed outside the electrode area. A pair of spiral electrodes (electrode 1 and electrode 2) are in the same plane. The two sets of spiral electrodes of the pair of electrodes are placed opposite to each other. The cross-sectional width of the spiral electrodes is 0.1mm-1.5mm, and the distance between the electrodes is 0.2mm. -5mm; a voltage of 50V to 2000V is connected to its input terminal, and the voltage is a frequency-adjustable square-wave AC power supply.

[0041] In short, as long as the parallel electrodes are covered on the surface of the equipment that needs to be dust-proof, the equipment can be kept in a dust-free environment. If transparent electrodes are used, they ...

Description

technical field [0001] The invention relates to a dust removal device, in particular to a plane dust removal device; it can be used for dust removal of solar cells or other equipment requiring dust removal in aerospace, industrial and civil fields, especially for dust accumulation on the surface of small-scale objects. Background technique [0002] Solar cells are one of the commonly used energy supply methods in aerospace, industrial and civil fields. However, there are a lot of dust on the moon, Mars and the earth. These dusts are gradually deposited on the panels of the batteries. When the dust reaches a certain level, the It will seriously reduce the energy conversion efficiency of solar cells. On the surface of optical devices such as CCD, if too much dust is deposited, it will also affect the use of equipment. [0003] The existing electrostatic precipitator used for these equipments that need to be dedusted uses a high-voltage electric field to ionize the gas, and th...
