Title:
REDUCTION-OXIDATION FURNACE FOR MAKING PHOSPHORUS BY THERMAL PROCESS
Document Type and Number:
WIPO Patent Application WO/2010/148899
Kind Code:
A1
Abstract:
A reduction-oxidation furnace (200) for making phosphorus by thermal process comprises a furnace body (50) and a spray gun (21, 26). The furnace body (50) comprises a slag outlet (23, 24), a flue gas outlet (22) and a molten mass inlet (27) through which molten phosphorus ores are added into the furnace body (50). One end of the spray gun (21, 26) is inserted into the furnace body (50). The reduction-oxidation furnace (200) for making phosphorus by thermal process can reduce the impurities in the flue gas with P2O5, which facilitates the extraction of the P2O5 with high purity and low cost.
