Embodiment 1
[0030] The water glass inorganic dedusting ash recovery method of the present embodiment may further comprise the steps:
[0031] (1) Sieve the inorganic dust removal dust of water glass, recycle the dust removal dust greater than 200 mesh as sand particles, and collect the dust removal dust not greater than 200 mesh;
[0032] (2) adding quartz powder to the collected dedusting ash of no more than 200 meshes, the quality of the quartz powder accounts for 8% of the mass of the dedusting ash no more than 200 meshes, and stir evenly to obtain the dedusting ash after treatment;
[0033] (3) Put the processed dedusting ash into a roasting furnace for roasting, the roasting temperature is 1600°C, and the roasting is stirred while roasting, the roasting time is 22min, and then cooled to normal temperature;
[0034] (4) The cooled dedusting ash is pulverized, and the pulverized particle size is less than 200 mesh, and dried to obtain the dedusting ash powder.
[0035] The inorganic w...

[0038] The water glass inorganic dedusting ash recovery method of the present embodiment may further comprise the steps:
[0039] (1) Sieve the inorganic dust removal dust of water glass, recycle the dust removal dust greater than 200 mesh as sand particles, and collect the dust removal dust not greater than 200 mesh;
[0040] (2) adding quartz powder to the collected dedusting ash of no more than 200 mesh, the quality of the quartz powder accounts for 10% of the quality of the dedusting ash no more than 200 mesh, and stir evenly to obtain the dedusting ash after treatment;
[0041] (3) Put the processed dedusting ash into a roasting furnace for roasting, the roasting temperature is 1700°C, and the roasting is stirred while roasting, the roasting time is 20min, and then cooled to normal temperature;
[0042] (4) The cooled dedusting ash is pulverized, and the pulverized particle size is less than 200 mesh, and dried to obtain the dedusting ash powder.

[0046] The water glass inorganic dedusting ash recovery method of the present embodiment may further comprise the steps:
[0047] (1) Sieve the inorganic dust removal dust of water glass, recycle the dust removal dust greater than 200 mesh as sand particles, and collect the dust removal dust not greater than 200 mesh;
[0048] (2) adding quartz powder to the collected dedusting ash of no more than 200 meshes, the quality of the quartz powder accounts for 12% of the quality of the dedusting ash no more than 200 meshes, and stir evenly to obtain the dedusting ash after treatment;
[0049] (3) Put the processed dedusting ash into a roasting furnace for roasting, the roasting temperature is 1800°C, and the roasting is stirred while roasting, the roasting time is 18min, and then cooled to normal temperature;
[0050] (4) The cooled dedusting ash is pulverized, and the pulverized particle size is less than 200 mesh, and dried to obtain the dedusting ash powder.
