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 to and at least one second reactor, including at least one reaction vessel, blender, cooling unit, heater, be used for fe and HNO3 the entry, be used for the second to contain export that nitrogen oxide flows and the export that is used for haematite nuclear suspension to 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 is by at least one the 7th circuit and at least one scrubber intercommunication. Utilize the equipment to produce red ferric oxide pigment and to have avoided containing the reaction product who does not want by high quality high yield high energy efficiency.
