Abstract
A single-region-board type high temperature electrostatic dust collector comprising anode boards (1), a cathode board (2), emitting electrodes (3) and a high voltage power supply is provided. Two parallel corrosion resistant plates are grounded to form the anode boards (1). One corrosion resistant plate with the same shape and size as the anode boards (1) connects to the cathode of the high voltage power supply, so as to form the cathode board (2), which are suspended between the two anode boards (1) and parallel with the anode boards (1). The disk-shaped emitting electrodes (3) are uniformly embedded at two sides of the cathode board (2).

1-2. (canceled)
A single-region-board type high temperature electrostatic dust collector comprising:
- a plurality of anode boards, a plurality of cathode boards, and a plurality of electron-emitting electrodes;
- a high voltage power supply;
- two parallel corrosion resistant plates being grounded to form the plurality of anode boards;
- wherein one corrosion resistant plate with a same shape and a size as the plurality of anode boards connects to the high voltage power supply, so as to form the plurality of cathode boards, which are suspended between two anode boards and parallel with the plurality of anode boards;
- wherein a plurality of disk-shaped emitting electrodes are uniformly embedded at two sides of the plurality of cathode boards.
The single-region-board type high temperature electrostatic dust collector of claim 1, wherein the plurality of electron emitting electrodes are made of a barium-tungsten thermal electron emission material doped cerium oxide, which comprises a mass percentage of 1˜2% CeO2 and 98˜99% tungsten powder, further wherein the porous tungsten matrix doped cerium oxide is impregnated with aluminates.
