METHOD FOR RECOVERY OF MUNICIPAL WASTES AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2007 - IPC F23G5/00 F23G5/20 

FIELD: processes and means for recovery of municipal domestic wastes in municipal engineering, may be used for recovery of industrial wastes practically in all branches of industry connected with generation of combustible wastes.

SUBSTANCE: apparatus has reactor with external heat-insulated housing, perforated charging drum placed within reactor and equipped with drive, main screw located within internal charging cavity of drum and rigidly connected at its one side with drive, and at its other side with drum. External surfaces of main screw and charging drum define space between internal surface of reactor and drum, wherein screw is rigidly fixed on external surface of charging drum. Reactor has gas discharge channels extending along reactor and communicated at their one sides with internal volume of reactor at side adjoining screw, and connected at their other sides with flue, burners located within reactor at side adjoining charging drum, charging device and air channels. Charging device has two rotating semi-containers whose walls, in conjunction with wastes charged therein, permanently close opening into reactor upon rotation of semi-containers during charging of raw material into opening. Roller supports are fixed on rector internal surface in contact with external surfaces of main screw and charging drum. Screw provided on external surface of charging drum defines countercurrent direction relative to main screw. Centrifugal fan mounted within flue is communicating through suction branch pipe with air volume defined by external surfaces of reactor with gas discharge channels and external housing, and through pressure branch pipe with air duct, burners and ejector for creating vacuum in reactor to remove flue gases.

EFFECT: reduced consumption of power for operation of this mobile apparatus and improved ecology control by eliminating contamination of environment with flue gases.
