METHOD AND DEVICE FOR ALLOTHERMIC PROCESSING OF CRUSHED ORGANIC WASTES BY HIGHLY SUPERHEATED STEAM Russian patent published in 2024 - IPC F23G5/00 

FIELD: processing and recycling of wastes.

SUBSTANCE: group of inventions relates to devices and methods for thermal processing of various organic crushed wastes, including toxic medical and industrial wastes. Method for allothermic processing of crushed organic wastes with highly superheated steam includes obtaining highly superheated steam in two detonation superheaters due to combined effect from detonation waves continuously circulating in each detonation superheater through combustible mixture, and on the side of heat-loaded walls of each detonation superheater on jets of low-temperature water vapor, and/or on liquid jets, and/or near-wall films of feed water, continuously supplied directly to each detonation superheater. Supply of highly superheated water vapor into the reactor in the form of continuous jets, accompanied by shock waves with the formation of stable high-temperature vortex structures in the reactor while maintaining high pressure to prevent suction of atmospheric air. Supply of wastes to the reactor, processing of wastes in the reactor using highly superheated steam with prevention of agglomeration of wastes particles due to action of both continuous supersonic jets of strongly superheated water vapor, and shock waves, connected to detonation waves continuously circulating in each detonation superheater to produce generator gas used in combustible mixture and/or directed to consumer, as well as a solid non-toxic residue sent to the consumer. Use of natural gas as backup fuel in case of shortage of generator gas. Pre-ground organic wastes are periodically fed into the reactor under the action of excess pressure created by the backup fuel and/or generator gas, obtained as a result of processing of previous portion of wastes and partially used for supply of crushed organic wastes into reactor.

EFFECT: exclusion of high-temperature jets of superheated water vapor from reactor and/or detonation superheaters into waste supply system, obtaining generator gas and a solid non-toxic residue without any harmful effect on the environment.
