ROTATING TILTED DRUM FURNACE FOR OXIDATING PROCESSING OF MATERIALS CONTAINING MODIBDENS Russian patent published in 2021 - IPC F27B7/10 

FIELD: petrochemical industry.

SUBSTANCE: invention relates to a rotary tilted drum furnace for oxidative treatment of molybdenum-containing materials. The furnace contains a metal drum with a combustion chamber having an internal refractory lining, equipped with annular rims mounted on support rollers fixed on the frame, and a girth gear connected by a mechanical transmission to the output shaft of the gearbox the input shaft of which is connected to the rotor shaft of the electric motor. The front end of the drum is combined with the combustion chamber, which has an automatic gas burner with a control unit and an unloading hatch, and the rear end of the drum is aligned with the gas chamber and the loading device. The drum is installed at an angle to ensure that the rear end is located above the front end. There is a branch pipe with a nozzle introduced into the drum from the side of its front end and having an electromechanical valve for supplying oxygen to it. There are wireless temperature sensors fixed on the drum surface at an equal distance from each other. An oxygen sensor is installed in the gas chamber. A control unit is fixed to the frame control configured to record measurements made by sensors. The control unit contains a Wi-Fi module. Temperature measurement sensors, a data input unit and an indication module are connected to the Wi-Fi module via a wireless network, while its first power output is connected to an electric motor, the second power output is connected to the control unit of the automatic gas burner, the third output is connected to the electromechanical valve of the branch pipe, and the oxygen sensor is connected to the measuring input by means of an operational amplifier.

EFFECT: design and possibility of conducting controlled experiments to optimize technological processes for processing spent catalysts in the petrochemical industry are provided.
