Provided is an efficient pulp and water mixing device. The efficient pulp and water mixing device comprises pulp and water mixing bodies (3) with mixing cavities (5), dilution water injection pipes (6), pulp pipe bundles (4) and turbulence pipes (1), wherein the dilution water injection pipes (6) are longitudinally led into the mixing cavities (5), the pulp pipe bundles (4) transversely penetrate through the mixing cavities (5), the turbulence pipes (1) and the pipe bundles (4) are connected, the turbulence pipes (1) are arranged in a concentric mode, turbulence pipe openings in the positions, connected with the pipe bundles, of the turbulence pipes are tapered openings (4-1) or cylindrical holes, the caliber of each tapered opening or each cylindrical hole is 1-4mm larger than the outer diameter of each pipe bundle, and annular gaps (2) are formed at the position of connection between the turbulence pipes and the pipe bundles. According to the efficient pulp and water mixing device, pulp and water in a flowing pulp box can be efficiently mixed, the pulp can be transversely and evenly distributed, and qualified paper can be made.
