CATALYTIC REACTOR FOR PROCESSING SEDIMENTS OF SEWAGE WATERS AND METHOD OF THEIR PROCESSING (VERSIONS) Russian patent published in 2014 - IPC C02F11/06 F23C10/01 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of processing sewage sediments, which contain organic substances, before their utilisation or burying. A catalytic reactor contains a case with an extension in the upper part, a pipe branch for the supply of a sewage water sediment, located at the level of connection of the lower and upper parts of the case, a pipe branch for discharge of an inert material and pipe branches for the supply of air and fuel, located in the lower part of the case, a pipe branch for the discharge of smoke gases and a pipe branch for loading the inert material, located in the upper part of the case, a gas-distributing grid, located between the pipe branches for air and fuel supply, on which located are particles of the disperse inert material, successively placed above the grid organising nozzle and heat-exchange surfaces, with the organising nozzle being made from materials, containing an oxidation catalyst. The method of processing sewage water sediments includes mechanical dehydration of the sediment, thermal processing of the concentrate in a fluidised bed of disperse particles, organised by an immovable nozzle, cooling solid processing products, separation of the solid products from smoke gases, processing the product with water solution of inorganic acid and application of the suspension for purification of initial sewage water.

EFFECT: invention ensures an increased efficiency of processing the sewage water sediments and elimination of contamination of the processing products with the catalyst dust.
