METHOD AND APPARATUS FOR NEUTRALIZING THE BACTERIAL CONTENT IN HOSPITAL WASTE OR OTHER SPECIAL WASTE, SO AS TO BE ABLE TO DISPOSE OF SAID WASTE AS ORDINARY WASTE

摘要

The invention relates to a method characterized by the sequence of at least the following working steps: introducing an accumulated mass of waste (V) which has been suitably shredded into a plurality of composite, pressure-resistant, treatment chambers (1, 5, 7, 7') which are screened with respect to the exterior and provided with windows (8) which are arranged suitably staggered with respect to each other and distributed at least along the height of the said accumulated mass and are connected to respective waveguides linked up to magnetrons (9) and are such that the microwaves produced by the latter are forced to strike said waste (V); preparing each said composite chamber, for treatment of the associated accumulated mass of internal waste, with appropriate moisture, pressure and temperature values and with suitable cycle times, preferably with implementation of a prior step involving internal depressuhsation of this composite chamber, which is filled, closed and ready for the sterilisation cycle; activation of the magnetrons (9) of the said composite chamber and rotation of the associated accumulated mass of internal waste (V) in relation to the said magnetrons which remain in a static position, so to obtain the uniformly distributed sterilisation of the said accumulated mass of waste, also using low-power magnetrons; releasing the pressure and the vapours from the said composite chamber so as to be able to open it safely and discharge from said chamber the sterilised waste
