Description
Technical field
The present invention relates to a kind of electric furnace method yellow phosphorus tail gas residual heat comprehensive balance and utilize system, yellow phosphoric tail gas cogeneration and thermodynamic equilibrium system that especially supporting producing yellow Phosphorus by electric oven uses.
Background technology
During producing yellow Phosphorus by electric oven Rock Phosphate (72Min BPL), silica, coke are mixed by ratio of components, in electric furnace, it is elemental phosphorous that phosphoric in the Rock Phosphate (72Min BPL) is reduced into, and coke is oxidized to carbon monoxide in this reaction process.The carbon monoxide that reaction produces wrap up in be with that gasiform is elemental phosphorous, ash and a small amount of water vapor overflow from electric furnace together, lower the temperature with the spray water washing through three grades of water cooling towers, make the elemental phosphorous of gas phase be condensed into liquid state and, enter the phosphorus recovery system with spray water with most of dust.Remaining gas comes out to form yellow phosphoric tail gas through three grades of water cooling towers, this yellow phosphoric tail gas calorific value: 10659KJ/Nm
3, smoke content: 73.3mg/Nm
3, oxide compound: 10.8mg/Nm
3, the exhaust gas component composition is roughly:
Under the normal circumstances, yellow phosphoric tail gas composed as follows:
