The invention discloses a medical plastic waste treatment device. The medical plastic waste treatment device comprises a combustion furnace, a water tank and an electrostatic adsorbing box; the a vertically arranged rotating shaft is arranged at the inner bottom of the combustion furnace, and is provided with a rotating furnace bottom; the rotating shaft is in transmission connection with a speedadjusting motor outside the combustion furnace through a transmission mechanism; an induced draught fan is arranged at the upper end of the combustion furnace, and is communicated with an S-shaped pipe vertically arranged in the water tank through a pipeline; the lower end of the S-shaped pipe is communicated with an oil and water separator; the upper end of the S-shaped pipe is communicated withthe right end of the electrostatic adsorbing box outside the water tank through a pipeline; a plurality of electrostatic adsorbing pieces are arranged in the electrostatic adsorbing box from left to right at intervals; and an air outlet with an exhaust fan is formed in the left end of the electrostatic adsorbing box. The medical plastic waste treatment device is reasonable in structural design, medical plastic waste can be sufficiently combusted, after tail gas of the medical plastic waste treatment device is filtered and cooled and is subjected to oil and water separating and dust removing, clean gas is obtained to be discharged out, the medical plastic waste is effectively treated, and the environment cannot be polluted.
