Abstract
The invention discloses a kind of yellow phosphorus slag that utilizes and directly become fine production method.The yellow phosphorus slag is a waste residue of producing yellow phosphorus, and is poisonous, amount is big.It is to be difficult to the three wastes problem handled for a long time.This law is that the high-temperature slag that the smelting yellow phosphorus electric furnace is discharged is directly made a kind of new energy-saving material---ca silicate fibre.Its goods can be widely used in the heat supply network of every profession and trades such as metallurgy, oil, chemical industry, light textile, electric power, machinery, the heat insulating of pipeline and the hot vessel below 700 ℃.Comprehensive utilization, the changing waste into valuable of yellow phosphorus slag, the purpose of improvement three wastes protection environment have been realized.Production cost is 1/2～1/4 of an identical scale rock wool production cost, and very big economic benefit and social benefit are arranged.
Description
The invention belongs to the comprehensive utilization of phosphorus production waste residue, particularly utilize the high-temperature slag of smelting yellow phosphorus electric furnace directly to produce a kind of production method of new energy-saving material-ca silicate fibre.
According to statistics, produce one ton of yellow phosphorus and discharge about ten tons of slags, Mianzhu Yellow Phosphorus Plant Sichuan Prov. will discharge 10,000 to 1.2 ten thousand tons of slags in 1989, the whole nation nearly 90 tame yellow phosphorus factories, and the slag annual emissions will be above 1,000,000 tons.The method of known this class slag of domestic and international processing mostly is to adopt the high pressure water of big flow that the blast furnace slag cooling is transported to scrap yard with grabbing to drag for to shovel again, produce a large amount of harmful steam polluting environments in the process of cooling, the heap waste residue will take a large amount of soils, is the industrial residue that needs to be resolved hurrily.Countries in the world are being developed and a kind ofly promptly are being incubated cold insulation, noise reduction fire prevention, having New Building Materials of high-strength light again in recent years, select for use rock wool or mineral wool all to be forced to stop because of involving great expense study.
Task of the present invention is the comprehensive utilization yellow phosphorus waste slag, and changing waste into valuable utilizes the high-temperature slag stream of phosphorus production discharging, in time, the material of construction of a kind of heat preserving and insulating material of development and production and high-strength light on the spot.
The main foundation that the present invention utilizes yellow phosphorus waste slag directly to produce the ca silicate fibre cotton is the phosphorus smelting theoretical temperatures and repeatedly surveys the slag exhaust temperature less than 1400 ℃, and the viscosity of melt is about 100～250 centipoises, and (%) is as follows for slag Chemical Composition and content:

Confirm that the slag that gives off possesses fibre-forming condition fully, the method for fiber that becomes of comprehensive aluminum silicate fiber and rock wool can be produced another kind of novel heat insulation lagging material-ca silicate fibre fully.
Task of the present invention is to finish like this: that utilize to smelt that yellow phosphorus electric furnace discharges meets fibre-forming condition (SiO
2/ CaO=0.75～0.85) high-temperature slag (without cooling, without shrend) pneumatics blows cotton technology and directly is blow molded into the ca silicate fibre cotton.(%) is as follows for the chemical composition of this kind cellucotton and content:

This ca silicate fibre has following advantage: do not need other consumes energy, do not need raw material in addition; Can replace the big rock wool of whole nation power consumption and produce, production cost is 1/2～1/4 of a rock wool production cost; Compare with 3000 tons of rock wool production lines of identical scale, can be country and save 5,000,000 degree electric energy; The goods of producing both can be made energy-saving material save energy 10～30%, can be incubated the material of construction of cold insulation, noise reduction fire prevention, high-strength light again.Turn waste into wealth thereby reach yellow phosphorus factory, administer the purpose of three wastes protection environment.Example of the present invention will be illustrated in conjunction with the accompanying drawings.
Accompanying drawing is that the yellow phosphorus slag blows cotton process flow diagram.

Outer V hole 20 hole φ 1.2～1.3mm
(7) graphite current plate 500 * 200 * 50mm
(8) receive cotton chamber 3000 * 1500 * 1000mm
With reference to accompanying drawing, its flow of air compressor machine (2) 3m is set in a side of slag chute
3/ hour, pressure 0.8MPa, opposite side is provided with the cotton chamber of netted receipts (8) of certain physical strength, high-pressure rubber pipe in gas-holder (3) connection of air compressor machine (2), install valve (5) on the pipe, pipe end is installed double V-shaped nozzle (6), when the yellow phosphorus high-temperature slag of material temperature＜1400 ℃ flow to chute from electric furnace (1) through graphite current plate (7), at this moment open valve (5) and make and blow cotton operating pressure and be controlled at 0.4～0.6MPa, can disposable slag be blow molded into linen ca silicate fibre cotton.
Because to being reduced separation in the strong reduction process of the most deleterious oxidation of impurities iron of fiber when smelting yellow phosphorus, other eutectic is volatilized, so ca silicate fibre is another novel cheap heat insulating and the material of construction that is independent of in mineral wool, rock wool, the aluminosilicate fiber cotton.The ca silicate fibre goods are widely used in the heat-net-pipeline of every profession and trades such as metallurgy, oil, chemical industry, light textile, electric power, machinery and the heat insulating of the hot vessel below 700 ℃.Mianzhu yellow phosphorus factory utilizes this factory's existence conditions to produce goods such as the felt of ca silicate fibre and short run, pipe, plate, brick on evidence fibre-forming condition good basis.Become method for fiber except that cotton technology is blown in employing, also can adopt centrifuging to produce.
