The invention discloses pore plate wave removing dispensing equipment used for carbon fiber precursor spinning, and belongs to the field of carbon fiber precursor spinning equipment. The pore plate wave removing dispensing equipment used for the carbon fiber precursor spinning aims at solving the technical problems that in existing various bath grooves used for carbon fiber spinning production, turbulence and wave phenomena occur in solutions and thus broken filament and entangled filament phenomena are easily generated. The pore plate wave removing dispensing equipment comprises a wave removing dispensing plate, the wave removing dispensing plate is a strip-shaped plate, through-holes are distributed in the strip-shaped plate, the through-holes present up-and-down misplaced arrays in the strip-shaped plate, wherein the pore diameters of the through-holes on the same layer are the same, and the pore diameters of the through-holes gradually become big from top to bottom. The pore plate wave removing dispensing equipment is used in bath grooves of solvent drafting devices, heat drafting devices or water washing devices of the carbon fiber precursor spinning equipment, medium flowing passes through the wave removing device, and due to the fact that the wave suffers the resistance of the plate face of the wave removing dispensing plate, the generation of turbulence and wave situations of the solutions in the bath grooves is reduced.
