Description
Technical field
The present invention relates to a kind of method of electric furnace process phosphorus production phosphoric acid byproduct potassium dihydrogen, belongs to mineral resources comprehensive utilization
With energy conservation field.
Background technology
Electric furnace process phosphorus production technique is to meet rock phosphate in powder, Silicon stone and the coke of manufacturing technique requirent（Anthracite）It is broken into
Certain particle size, is released by a certain percentage in batches by warehouse respectively, is then delivered to electric furnace feed bin with uniformly compound.Mixing
Expect that seven tremie pipes by equally distributed connection electric furnace body with feed bin are continuously introduced in closed pressure-fired electric furnace.The three of electric furnace
Phase electrode（Three or the six roots of sensation）Work in its rated power or so, the compound of entrance electric furnace is occurred at 1400-1500 DEG C
Reduction reaction.The slag and ferrophosphorus of generation is periodically discharged from furnace bottom, and ferrophosphorus is reclaimed at slag road, and slag enters slugging pond（Or water
Quench flushing cinder pond）, and pick up in time and transport.The furnace gases such as the yellow phosphorus of generation, CO, Silicon fluoride. are escaped from reaction melting zone, through stove
The dust in a part of compound is carried during the compound of internal upper part continuous supplementation, three absorptions that series connection is entered by airway
Tower, through the circulating sewage spraying cooling that turbidity is relatively low, temperature and pressure is suitable, yellow phosphorus is condensed into drop and is entered tower together with dust
Bottom is received in phosphorus groove, as thick phosphorus.Thick phosphorus after steam heating, stirring, clarifying, deposits pure phosphorus in the bottom of a pan, afterwards in refining kettle
Condensation reservoir is entered, and product yellow phosphorus is obtained final product after cooling shaping, metering packing is carried out to finished product phosphorus again finally.The gases such as CO（That is tail
Gas）, be divided into two-way through total water seal, be all the way through further purify after as fuel or be used as one Chemical Manufacture raw material of carbon, but
Great majority are processed using emptying.
The main chemical reactions of electric furnace process phosphorus production are：
4Ca5F(PO4)3+ 21SiO2+ 30C → 3P4↑+30CO ↑+SiF4↑+20CaSiO3；
