METHOD OF PROCESSING OF SOLID ORGANIC WASTES, PLANT AND DESTRUCTION FOR ITS EMBODIMENT Russian patent published in 2000 - IPC

FIELD: methods and plants for processing of solid organic wastes by flameless burning in melt of salts and alkalis; applicable in chemical, petrochemical, nuclear and other industries. SUBSTANCE: method of processing of solid organic wastes in melts of salts and alkalis at temperature of 400-900 C includes supply of solid organic wastes and gases, and withdrawal of obtained products. Supply of solid organic wastes into melt is carried out together with inert gas. Melt regeneration is accomplished with oxygen-containing gas. Solid organic wastes are preliminarily treated. Solid organic wastes and gases are introduced to under surface of melt. Processing of solid organic wastes and melt regeneration are separated in space and carried out simultaneously. Temperature of melt in course of waste processing is raised, and effluent gases of solid organic waste processing and effluent gases of melt regeneration are subjected to cleaning. Plant for processing of solid organic wastes in melt includes destructor, secondary combustion chamber, unit for removal of acid gases and solid particles. Secondary combustion chamber has fluidized bed with inert packing. Unit for removal of acid gases and solid particles is made in form of countercurrent reactor of hindered settling of chemisorbent. Installed successively after said unit are catalytic reactor and heat exchanger. Destructor for processing of solid organic wastes in melt consists of body, cover, reaction and regeneration pipes, pipe unions for admission of gases and wastes, and withdrawal of reaction products. Space above melt under cover is separated into three zones formed by partitions immersed into melt. Pipe unions for admission of gases and wastes are immersed into melt and form gas lift reactors together with reaction and regeneration pipes. EFFECT: higher efficiency and reliability of processing of solid organic wastes in melt of salts and alkalis. 8 cl, 2 dwg, 2 ex
