METHOD AND DEVICE FOR RECYCLING OF RUBBER WASTES Russian patent published in 2009 - IPC B29B17/00 C08J11/14 F23G5/27 B09B3/00 

FIELD: technological processes.

SUBSTANCE: invention is related to technology for recycling of industrial and household wastes and provides for reduction of power inputs, reduction of hazardous emission into environment and increased quality of wastes recycling products. Method for recycling of rubber wastes includes their pyrolysis in reactor in coolant medium, separation of pyrolysis products into gaseous and solid phases, cooling of solid phase by means of water supply, separation of liquid phase from gaseous phase by means of condensation, burning of gaseous phase for coolant heating in heat exchanger. Solid phase is supplied in mill, where water is simultaneously sprayed, and wet grinding of solid phase is carried out to prepare suspension, and the first fraction of liquid phase is separated from gaseous phase by means of condensation, afterwards by means of condensation the second phase of liquid phase is separated, and then water is separated from the second phase, and the first fraction is mixed with suspension, and mixture is exposed to mechanical and mechanical activation by means of cavitation excitation. After separation of the second fraction of liquid phase part of gaseous phase is burned, and remaining part of gaseous phase is mixed with reheated water vapor and used in the form of coolant. Water used to prepare suspension is water separated from the second fraction. Device for processing of rubber wastes by method according to invention is characterised by heater installation with furnace in working chamber, use of heater in the form of shell and tube heat exchanger of rectangular cross section and installation of loading chambers on opposite sides of working chamber, and loading chambers are combined with cooling chambers.

EFFECT: invention discloses quantitative parametres of modes and operations of methods.
