Abstract
The invention provides a kind of novel process of using the molten slag fluid direct production mineral wool of the coal-fired vertical cyclone furnace cinder notch discharge in fuel-burning power plant, the processing method that replaces general known production mineral wool, the material calcining melting process that has saved known mineral wool production technique, but save energy consumes about 60%, greatly reduce the mineral wool production cost, remedied the deficiency of known production mineral wool processing method.The present invention directly adopts molten slag fluid that the vertical cyclone furnace cinder notch discharges as the molten stream of producing mineral wool, with steam or air blown method, or will melt stream with mechanical centrifuging and make mineral wool fibre.
Description
The present invention relates to a kind of novel process with fuel-burning power plant coal-fired vertical cyclone furnace molten slag direct production mineral wool.
The processing method of general known production mineral wool, be to produce the raw material of mineral wool, as basalt ore, diabase ore, blast-furnace slag etc., mix with the mineral of fluxing in right amount (as Wingdale, rhombspar), equipment calcination through fusing ores such as tank furnace, cupola furnace or electric furnaces, make into the high-temperature melt flow of cotton usefulness, make mineral wool through mechanical centrifuging or gas blowing process again.The processing method that this class is produced mineral wool need expend a large amount of energy with a large amount of cokes or electric energy; Technological process is complicated, and production cost is higher.
Coal-fired vertical cyclone furnace is the power-equipment that the fuel-burning power plant produces high pressure steam, discharges a large amount of molten slags in operational process, annual bed drain purge tons up to ten thousand.How to fully utilize these residue resources, reduce the deslagging expense, reduce environmental pollution, this is the big problem of one in the environment protection.
The objective of the invention is to; a kind of novel process of using the molten slag fluid direct production mineral wool of the coal-fired vertical cyclone furnace cinder notch discharge in fuel-burning power plant is provided; replace the processing method of general known production mineral wool, and manage to solve and utilize this environment protection problem of fuel-burning power plant residue resource.
The present invention adopts following method to realize:
In bunker coal, mix quantitative Wingdale, so that reduce the temperature of cindery fusing point and cinder notch molten slag in the vertical cyclone furnace; The molten slag fluid that directly adopts the discharge of vertical cyclone furnace cinder notch is as the molten stream of producing mineral wool, to melt stream with steam or air blown method and be blow molded into mineral wool fibre, perhaps will melt stream causes will melting stream with mechanical centrifuging and making mineral wool fibre on the mechanical centrifugation apparatus (as four roller whizzers) by diversing flow system.The reprocess fibre settling pocket collects the mineral wool fibre of making, and promptly can be made into various mineral wool products.
Among the present invention, it is 1300～1560 ℃ with becoming cotton temperature range that the molten slag fluid that coal-fired vertical cyclone furnace cinder notch is discharged is suitable for deslagging.
The Wingdale that mixes in the bunker coal is (10～25)/100 with the ratio of the weight of coal, Wingdale can replace with rhombspar, rhombspar and Wingdale are used with and also can, if fuel pit ash fusing point is lower, do not mix Wingdale and the molten slag fluid temperature (F.T.) that the cyclone furnace cinder notch is discharged can be controlled in 1300～1560 ℃ of scopes yet, can not mix Wingdale in the coal.
Most preferred embodiment of the present invention:
The molten slag fluid temperature (F.T.) that the cyclone furnace cinder notch is discharged is 1380～1420 ℃;
The chemical constitution of molten slag (weight percentage):
SiO
238～41
Fe
2O
36～7
Al
2O
322～23
CaO 25～30
MgO 0.6～1.51
SO
30.05～0.07
The weight ratio of Wingdale and bunker coal is 18/100.
The mineral wool unit weight that the present invention produces is 60～100kg/m
3, the mineral wool fibre diameter is 3～8 μ, and thermal conductivity is 0.03～0.055Kcal/mh ℃, and thermal stability is 700 ℃, and slag ball content is below 5%.
The present invention has simplified the process of general known slag wool production, the material calcination fusion process that has saved known mineral wool production technology, can reduce energy resource consumption about 60%, greatly reduce the mineral wool production cost, open up a new way of thermal power plant residue resource comprehensive utilization, remedied the deficiency of known slag wool production process.
