Device for producing red iron oxide pigment

The utility model relates to an equipment for producing red ferric oxide pigment. includes at least one initial response ware at least, including at least one reaction vessel, blender, cooling unit, be used for HNO3 and iron the entry, be used for first contain export that nitrogen oxide flows and the export that is used for ferrous nitrate (II) solution to and at least one second reactor, and at least one third response ware, and at least one scrubber, and at least one exhaust purification unit and at least one heater, at least one exhaust purification unit feeds through by at least one the 8th circuit and at least one heater, and at least one heater utilizes the equipment just to have avoided containing the reaction product who does not want by high quality high yield high energy efficiency production red ferric oxide pigment by at least one the 7th circuit and at least one scrubber intercommunication.
