The invention provides high pressure air injection eddy making type eddy kinetic energy pulping equipment which mainly comprises a thick liquid generating device, a high pressure air supply device and a high pressure air injection eddy making device. The high pressure air injection eddy making type eddy kinetic energy pulping equipment is characterized in that the high pressure air injection eddy making device generates eddies inside a pulper cylinder, and an upper baffle and a lower baffle shear and beat the eddies during eddy fluid motion. Pressurizing and acceleration of gas are achieved through the dip angle design of a tilting tray. A turbulent flow block at the tail end of the tilting tray is prevented from being disengaged from fluid to generate eddies and secondary pressurizing and acceleration are achieved. Due to the dip angle design at the initial end of an air injection channel, gradual change of the air flow direction is achieved, and kinetic energy losses are reduced. Gentle direction changing, repeated pressurizing and acceleration and small kinetic energy losses can be achieved through the circular bead optimal design of the middle end and the initial end of the air injection channel. Due to the fact that triangular sawteeth are arranged and the upper and lower baffles are arranged in a staggered mode, all-directional shearing and beating of crushed aggregates are achieved, and the pulping efficiency is improved.
