In 1- of embodiment of the present invention embodiment 9, incineration of refuse flyash feeds electric smelting by flying dust feeding system and melts hardening and tempering furnace
In；Electric smelting melts the flue gas generated in hardening and tempering furnace and is discharged into flue gas purification system, is handled through desulphurization and denitration, dust-extraction unit, up to standard
After discharge；The secondary flying ash of flue gas purification system trapping is collected by outlet, is determined according to the property of the secondary flying ash of collection
Surely be mixed into flying dust feeding system be added again electric smelting melt hardening and tempering furnace preparation heat-preservation cotton or in the form of crude salt collect storage.
Incineration of refuse flyash is added ironmaking warm sludge by solid phase or liquid phase mode and prepares heat-preservation cotton in the present invention, realizes rubbish
The innoxious and resource utilization of flying ash；The state of incineration of refuse flyash can be powdered, shaped granule shape, forming blocks
Shape is spherical, is also possible in melting liquid phase state, can also be that incineration of refuse flyash and auxiliary material are preheated to certain temperature
Degree is then added to electric smelting and melts in hardening and tempering furnace.Incineration of refuse flyash and auxiliary material are added to electric smelting in solid form and melt in hardening and tempering furnace,
The advantages of this mode is that cost is minimum, treatment process is simple, the disadvantage is that mixing melts in electric smelting melts homogenising time in hardening and tempering furnace
It is long, and it is irregular that stirring can be generated in the case that collaboration amount is big.Electric smelting is then added to after incineration of refuse flyash and auxiliary material mixed melting
Melt in hardening and tempering furnace, the advantages of this mode be when additional amount is big material mixing sufficiently quickly, uniformity it is good, the disadvantage is that cost compared with
Height, process system are more complex.Electric smelting is then added to after incineration of refuse flyash and the uniformly mixed preheating of auxiliary material to melt in hardening and tempering furnace, it is this
The advantages of mode is without reaching full-fusing liquid phase, and cost is low compared with full-fusing, and the two mixing uniformity is good.
The present invention prepares heat-preservation cotton using ironmaking warm sludge collaboration incineration of refuse flyash, is on the one hand protected using ironmaking warm sludge preparation
The high-temperature technology of warm cotton technology carries out high-temperature process to incineration of refuse flyash, on the other hand will facilitate to make in incineration of refuse flyash
The element of cotton hardening and tempering process is recycled, and realizes innoxious, the resource utilization of incineration of refuse flyash；And the heat-preservation cotton of preparation
Thermal coefficient between 0.025-0.035W/ (mk), meet the relevant target level of product quality GB/T11835 of mineral wool.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
