Description

Technical Field

[0001] The utility model relates to the technical field of electric dust removal, in particular to an electric dust removal and flushing device for a high coal furnace. Background Art

[0002] Electrostatic precipitator generally refers to electrostatic precipitator, which is a method of gas dust removal. When dust-containing gas passes through a high-voltage electrostatic field, it is electrically separated. After the dust particles combine with negative ions and carry negative charges, they tend to discharge to the anode surface and deposit. The dust of high-coal furnace flue gas is directly discharged to cause environmental pollution. The electrostatic precipitator performs dust removal operation on the high-coal furnace flue gas. During operation, a large amount of dust will adhere to the dust filter. In order to ensure the normal operation of the dust removal, a flushing device is used to clean the dust filter. For example, a Chinese patent discloses a high-coal furnace electrostatic precipitator flushing device (authorization announcement number CN217615325U). The patented technology drives the rotating rod to rotate by a motor, so that the cam on the rotating rod rotates. The cam rotates and drives the push plate to move, so that the dust collecting plate on the top surface of the push plate moves, which can effectively drive the dust collecting plate to move back and forth, so that the dust on the dust collecting plate can be shaken off, which is convenient for improving the cleaning effect of the dust collecting plate.

[0003] However, the existing high-coal furnace electrostatic precipitator flushing device still has some defects that need to be improved in practical application, such as:
