The invention provides a rotary atomized self-absorption wet-type dust removal device. The rotary atomized self-absorption wet-type dust removal device comprises a circulating water tank, a rotary atomized self-absorption spray device installed in a tower body, a center shaft assembly, the tower body and a mist eliminator, a rotary atomized propeller serves as the spray device of the wet-type dust removal device, by means of powerful thrust produced through rotation of an injection driven spray nozzle working in a critical state, water is atomized into liquid drops of 20 micrometers to 100 micrometers, the contact area between dust and the water can be large, and therefore the high efficiency of removing the dust with a dust remover is guaranteed. Meanwhile, negative pressure is formed through a jet flow in the rotary atomizing process, the suction effect on dusty gas flow is achieved, part of system resistance is overcome, fan energy consumption is reduced, and therefore the operating cost is reduced. Empty tower spraying is conducted, and the mist eliminator is arranged on the tower top to prevent entrainment.
