The invention relates to abrasive water jet ship repair rust removal equipment which comprises a rust removal shell, a spray pipe assembly capable of rotating in the rust removal shell and a plurality of spray head assemblies, the rust removal shell comprises an upper shell and a lower shell, the spray pipe assembly comprises an inner pipe, a middle pipe and an outer pipe, and each spray head assembly comprises a first high-pressure water pipe, a second high-pressure water pipe, an abrasive pipe and a spray nozzle. A first high-pressure water cavity is arranged in the inner pipe, in the first high-pressure water pipe and between the second high-pressure water pipe and the nozzle, a second high-pressure water cavity is arranged between the upper shell and the middle pipe, between the middle pipe and the inner pipe and in the second high-pressure water pipe, and abrasive cavities are arranged between the lower shell and the outer pipe, between the outer pipe and the middle pipe and in the abrasive pipe. The rotating spray head assembly is matched with the spray holes to effectively improve the rust removal breadth and efficiency, grinding materials adsorbed through negative pressure are mixed with high-pressure water jet for the first time and then mixed with high-pressure water for the second time through the mixer, the mixing efficiency and material kinetic energy are improved, the erosion continuity, uniformity and stability are guaranteed, and the efficient and high-quality surface treatment effect is achieved.
