Water supply type seawater ice-making system based on vaporific direct injection

The invention discloses a vaporific direct injection water supply type seawater ice-making system which comprises a control system, a man-machine interaction system (1), an ice-making bucket and a compressor (7), vaporific direct nozzles (15) of the same specification are installed on an inner main shaft of the ice-making bucket at equal intervals in the vertical direction, and the vaporific direct nozzles (15) are connected with the compressor (7). Pressurized seawater is sprayed to the inner wall of the ice-making bucket through an inner runner of the main shaft and a vaporific straight spray head (15), the seawater uniformly covers the interior of the ice-making bucket, a larger heat exchange area is obtained in unit time, the ice-making efficiency is further greatly improved, meanwhile, a compensation ice-making section is arranged at the bottom of the main shaft to reduce the residual amount of the seawater, and the ice-making efficiency is improved. A water receiving tank is arranged at the bottom of th
