The present invention is provided with a continuous discharging slag device on yellow phosphorus electric furnace, when slag is flowed through the continuous discharging slag mouth, make the upper end of slag stream strand aligning high velocity air pipe nozzle or four roller high speed centrifugation glass wool making machines through thrust-augmenting nozzle, through high velocity air or four roller high speed centrifugation glass wool making machines, directly make aluminosilicate calcium fiber, add an amount of binder solution then and can be processed into inexpensive light-duty hard, the semi-rigid warming plate, acoustic panel, decorative sheet, high temperature insulation panel and pipe insulation material, can greatly improve economic benefit of enterprises, the heating energy source that can economize in raw materials in a large number simultaneously has bigger social benefit and application value widely.
Description
The present invention directly utilizes the yellow phosphorus furnace slag of red-hot molten state to make the method for mineral wool on the electric furnace of producing yellow phosphorus.
Relevant by retrieval patent documentation still finds no identical with the present invention method of being made mineral wool by yellow phosphorus furnace slag.Produce at present in the chemistry reflection process of yellow phosphorus, beyond its basic product one element phosphor, also have three kinds to pay product: to be formed 85～90% gas by carbon monoxide; Ferrorphosphorus; Slag.Carbon monoxide and ferrophosphorus all obtain rational Application.To yellow phosphorus furnace slag be used for casting slabstone, the rectangular slab of stone; Alumina slag to aluminiferous cement waters ingot bar stone, fragmentation, sorting then, send construction sector's usefulness of paving the way; Adopt high velocity flow, water waterfall granulated processed when slag flows out, the slag of granulation is for cement mill slakin cement.The granulation water consumption, 10～12 tons of slag waters per ton.The power consumption of making one ton of yellow phosphorus is 14000～17000 degree.Discharge ten tons of slags and produce one ton of yellow phosphorus, it is 400 card/kilograms that its heat contains, and slag in fact per ton has consumed 1400～1600 degree electric energy and directly discharged, and consumes water again with its cooling, and what these heat energy were fearless loses.
The objective of the invention is to provide a kind of, in the red-hot production process of electric furnace, red-hot yellow phosphorus furnace slag is directly made the aluminosilicate calcium fiber method, and then make mineral wool series insulating material for improving the use value of yellow phosphorus furnace slag.
Technical characterictic of the present invention is: the slag of discharging in the phosphorus production contains small amount of impurities Cp
2O
3, MgO, FeO, TiO
2Aluminum calcium silicate form, its Chemical Composition is: CaO40～50%, SiO35～42%, AL
2O
32～5%.Fusing point is 1350～1400 ℃, and viscosity is 4 pools (1500 ℃).These chemistry of yellow phosphorus furnace slag, physicals possess directly carries out the condition that mineral wool is made in the fibrosis processing to slag melt stream thigh.The present invention is provided with a continuous discharging slag device on yellow phosphorus electric furnace, when slag is flowed through the continuous discharging slag mouth, make stream strand aligning high velocity air or aim at four roller high speed centrifugation glass wool making machines upper end through the thrust-augmenting nozzle extension, through high velocity air or four roller high speed centrifugation glass wool making machines, directly make aluminosilicate calcium fiber, add an amount of tackiness agent then and can be processed into hard, semi-rigid warming plate, acoustic panel, decorative sheet, high temperature insulation panel and piping insulation goods.
Advantage of the present invention is to adopt red-hot fused yellow phosphorus furnace slag directly to make mineral wool, can greatly increase economic efficiency, the yellow phosphorus furnace slag pin is given only 18 yuan/ton in cement mill, makes mineral wool product and can sell 1000 yuan/ton, utilization ratio in 50%, a factory that produces 1000 tons of yellow phosphorus per year can increase 5,000,000 income; While is save energy effectively, produces one ton of lagging material and needs power consumption 1700 degree electricity, and the present invention makes mineral wool with the red-hot yellow phosphorus furnace slag in chemical production, and heating energy source in a large number can economize in raw materials.Calculate by the yellow phosphorus electric furnace of producing 1000 tons per year, produce yellow phosphorus every day and discharge 40 tons in slag for 4 tons, as produce 50% mineral wool, can save the electricity of degree more than 30,000, have bigger social benefit; For building materials department provides inexpensive light-duty lagging material, and create favorable conditions for squeezing into the international market.
Below in conjunction with the description of drawings embodiments of the invention:
Accompanying drawing 1 is the synoptic diagram of yellow phosphorus technology Electric Cooker mineral wool method.
Accompanying drawing 2 is synoptic diagram that the yellow phosphorus stove is made the mineral wool method outward.
Shown in accompanying drawing 1, in order directly to produce mineral wool at the yellow phosphorus electric furnace slag notch, two slag notches at original yellow phosphorus electric furnace (7) are provided with a continuous discharging slag mouth again, and the slag notch of continuous discharging slag (3) is higher than ferrophosphorus slag notch (2), subnormal interruption slag notch (1).The flow of controlling continuous slag notch simultaneously must be equipped with a thrust-augmenting nozzle (4) at continuous slag notch and extend forward less than the rate of growth of slag, so that make the melt-flow thigh aim at high velocity air nozzle (6) or four roller high speed centrifugation glass wool making machines.Electric heater (5) preheating is equipped with in thrust-augmenting nozzle bottom, guarantees thrust-augmenting nozzle unlikely plug that freezes when beginning, when hot slag is discharged the water conservancy diversion mouth of pipe, through the high velocity air blowing or adopt four roller supercentrifuges to produce slag fibre.
Shown in accompanying drawing 2: no locus is provided with system mineral wool device before yellow phosphorus electric furnace, available cinder ladle enters slag (12) in the stokehold by interruption, transport to system mineral wool workshop, this moment, cinder ladle was again simultaneously lonely (resistance) body of heater (11) of electricity, by electric current, carry out additional heat through electrode (15), also can require to add other raw materials simultaneously and carry out the slag levelling according to slag, as add clay, alumina, improve mineral wool quality.Slag is discharged at slag mouth (13), and slag stream plume is gone into four roller supercentrifuges (14) and made mineral wool.
Claims (3)
1, the red-hot yellow phosphorus furnace slag of a kind of usefulness its technical characterictic of method of directly making mineral wool is: a continuous discharging slag mouth is set on yellow phosphorus electric furnace, when red-hot yellow phosphorus furnace slag is discharged thrust-augmenting nozzle, adopt high velocity air, or four roller supercentrifuges is made mineral wool.
2, method according to claim 1 is characterized in that: the slag notch of continuous discharging slag is higher than the ferrophosphorus slag notch, and subnormal indirect slag notch is equipped with a thrust-augmenting nozzle at continuous slag notch, and the electrically heated preheater is equipped with in the bottom of thrust-augmenting nozzle.
3, method according to claim 1 is characterized in that: the cinder ladle double as heating furnace body of contain yellow phosphorus furnace slag, red-hot yellow phosphorus furnace slag is expelled to four roller supercentrifuges through the slag mouth and makes mineral wool.
