Patent ID: 7901638

Claim:
An oxidizing reactor for molybdenum sulphide wherein said reactor consists of: a first body forming a reaction chamber and having an external surface made from a heat resistant material and an internal surface which is lined with a refractory lining; a feeding bin for feeding molybdenum sulphide concentrate to the first body; a dispenser between the feeding bin and the first body for receiving the molybdenum sulphide concentrate from the feeding bin and supplying the molybdenum sulphide concentrate to the first body; a first set of magnetrons for ionizing the molybdenum sulphide concentrate in the first body; a winding coil for generating a variable magnetic field for heating of the molybdenum sulphide concentrate in the first body and to exclusively evaporate the molybdenum sulphide concentrate; a second set of magnetrons and an air injector for oxidizing the evaporated molybdenum sulphide in the first body to form molybdenum trioxide with release of heat; an extraction screw for collection and removal of solid particles of impurities from the first body; a second body forming a reaction chamber having an external surface made from a heat resistant material and an internal surface which is lined with a refractory lining; a first duct for conducting hot gases from the first body towards the second body, wherein the hot gases essentially contain molybdenum trioxide, sulphur dioxide, and nitrogen; a second duct for adiabatic cooling of the hot gases and located in an upper portion of the second body so as to inject cold air to cool the molybdenum trioxide gas below its sublimation point and to render the molybdenum trioxide gas into crystals; a lower duct located in a lower part of the second body for removing the crystals; and a higher duct located in a higher part of the second body for removal of gases for cooling and cleaning purposes.
