The invention provides a wet electric dust collector anode, and belongs to the field of environmental engineering. The electric dust collector anode is shaped as honeycomb and is made of a polyvinyl fluoride plate having a surface layer spray-plated with a conductive substance. The thickness of the polyethylene fluoride plate is 0.3-3.0 mm, and the high-conductive conductive spray-plated on the surface layer of the polyvinyl fluoride plate is carbon fibers. Six corners of the honeycomb comprise no carbon fiber coating layers. The wet electric dust collector anode has the advantages of strong corrosion resistance, light weight and low cost, has the rigidity equivalent to a currently widespread used rigid anode-glass steel, and has the high-temperature resistance, acid and alkali resistance and toughness far more than those of the glass steel; the service life is 1.5 times that of the glass steel; the price is 1/2 that of a glass steel anode plate. The electric dust collector anode solves the problems that the conventional anode has too large weight, a base frame is unable to load, the anode is easy to corrode and the cost is high.
