Title:
DEVICE MAKING PHOSPHORUS BY THERMAL PROCESS
Document Type and Number:
WIPO Patent Application WO/2010/148902
Kind Code:
A1
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.
