Flat-plate fogdrop trapping device

The utility model provides a flat fogdrop trapping device. A plurality of trapping units are arranged in a shell of the flat fogdrop trapping device; the trapping unit comprises two plate electrodes which are arranged in parallel, and a plurality of driving electrodes which are arranged between the two plate electrodes and are electrically connected with each other; the driving electrode is a metal rod with a smooth surface, the diameter is not larger than 5 mm, and the driving electrode is connected with the high-voltage end of the high-voltage power source. And the low-voltage end of the high-voltage power supply and the plate electrode are grounded. The driving electrode can generate an extremely strong non-uniform high-voltage electrostatic field, after fog drops enter the trapping device from the inlet, due to the fact that the center of negative charges deflects towards oxygen atoms, and meanwhile the mass of the oxygen atoms is larger than that of hydrogen atoms, under the towing effect of the oxygen a
