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.

Abstract
A device making phosphorus by thermal process comprises a melting furnace (100) and a reduction-oxidation furnace (200). The melting furnace (100) melts phosphorus ores into molten mass and has a feed inlet (11) and a molten mass outlet (14). The reduction-oxidation furnace (200) comprises a spray gun (21, 26) and a furnace body (50) having a molten mass inlet (27), a slag outlet (23, 24) and a flue gas outlet (22), wherein the molten mass inlet (27) is connected to the molten mass outlet (14) and one end of the spray gun (21, 26) is inserted into the furnace body (50). The device 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.
