METHOD FOR THERMAL DISINFECTION Russian patent published in 2016 - IPC B09B5/00 A61L11/00 

FIELD: processing and recycling of wastes.

SUBSTANCE: method is intended for disinfection of large-capacity waste biomass, in particular excrements, decontamination of soils containing botulinus toxins, poisons tetanus, spores and seeds of weeds, decontamination and processing of dead animals, burial grounds, medical, municipal and other wastes. For thermal disinfection raw material is milled. Crushed raw material is mixed with water to create pulp with fluid consistency. Pulp is continuously fed by pump via recuperative heat exchanger in heated flow thermal chamber. Raw material is heated and held in chamber for sterilization. Pump provides pulp pressure above water vapour pressure at current temperatures in heat exchanger and chamber. Processing products are cooled in heat exchanger using heat exchange with pulp fed to processing. Pulp is fed to processing by way excluding mixing thermally processed raw material and thermally treated products. Decontaminated products are extracted from chamber through throttling valve. Valve maintains specified pressure in heat exchanger and chamber.

EFFECT: invention increases efficiency of decontamination of wastes.
