Abstract:
The present invention includes an apparatus and method for processing solid waste products. The apparatus comprises a rotatably mounted cylindrical vessel having a first end, a second end and an interior surface, at least one end terminating in a hatch that may be opened to allow access to the interior of the vessel and sealably closed to allow pressurization of the vessel; a steam inlet for injecting stem disposed at one or both ends; a plurality of substantially straight blades protruding from the interior surface of the vessel, and each the blade extending substantially the entire length of the vessel, so as to be capable of transporting waste material from the bottom of the vessel toward the top of the vessel, and releasing the waste material to fall to the bottom of the vessel. The apparatus also includes one or more actuators for moving the vessel between a position wherein the first end is higher than the second end and a position wherein the second end is higher than the first end.

Abstract:
The present invention includes systems, apparatus and methods for processing solid waste products. The present invention includes an apparatus and method of processing solid waste products in an autoclave, comprising the steps: (a) loading the autoclave with a charge of solid waste products containing water; (b) sealing the autoclave; (c) rotating the autoclave while heating the autoclave such that the charge of solid waste products containing water creates steam in the autoclave, and whereby so waste liquid water or steam and cellulosic material are produced; (d) conducting liquid water or steam from the autoclave to a water cleaning system and then to a heat recovery steam generator so as to generate steam therefrom; and (d) reintroducing the steam generated by the heat recovery steam generator into the autoclave. The system preferably is a closed loop system to conserve water. The system also includes equipment to convert cellulose into fuels and energy, and some of the fuels and energy are directed to the production of electricity and steam to support the needs of the autoclave and the balance may be commercially sold.
Abstract:
An autoclave system provides a means of sterilizing municipal solid waste, hydrolyzing many of its components, and preparing the material for post-autoclave automated separations. The present apparatus provides a means of drying the solid waste in the vessel, while conserving the energy used to dry the vessel. Non-contact steam is recovered through separations of steam and water, with condensate steam pressure regenerated by mechanical vapor recompression and condensate water returned to the boiler/steam generator. Heat transfer to combustion air, by heat transfer via heat pump to generate additional steam, and/or by mechanical vapor recompression recovers the latent heat of loose contact steam condensate. The process design provides for in-vessel drying while reducing the energy cost of operating a waste autoclave, as compared to the current art.
