Embodiment 1
[0023] All the limestone is crushed to pass through a 120-mesh sieve, and the particle size is below 0.125 mm. The carbide slag is mixed with the crushed limestone at a mixing ratio of carbide slag:limestone=4:1, and then stirred evenly to obtain a sulfur-fixing agent. Among them, the portion of the calcium carbide slag with a particle size of 10-50 μm accounts for 80% of the total weight of the carbide slag.
[0024] Fully mix high-sulfur coal gangue (sulfur content 5.24%), washed gangue and shale at a weight ratio of 30%, 10% and 60% respectively, and then crush it to a size below 2mm, and the part with a particle size below 0.3mm Accounting for 71% of the total weight of high-sulfur coal gangue, washing gangue and shale, the calorific value of the mixed material is 450kcal / kg; adding a sulfur fixative, the amount added is 4% of the total weight of high-sulfur coal gangue and shale %, to obtain brick-making materials.
[0025] Add water to the brick-making material and stir...
Embodiment 2
[0030] All the limestone is crushed to pass through a 120-mesh sieve, and the particle size is below 0.125 mm. The carbide slag is mixed with the crushed limestone at a mixing ratio of carbide slag:limestone=1:1, and then stirred evenly to obtain a sulfur-fixing agent. The portion of the calcium carbide slag with a particle size of 10-50 μm accounts for 70% of the total weight of the carbide slag.
[0031] Fully mix high-sulfur coal gangue (sulfur content 5.24%), washing gangue and self-combustion gangue at a weight ratio of 30%, 20% and 50% respectively, and then crush them to a size below 2mm, and the part with a particle size below 0.3mm Accounting for 72% of the total weight of high-sulfur coal gangue, gangue washing and self-combustion gangue, the calorific value of the mixed material is 500kcal / kg; adding a sulfur fixation agent in an amount of 5% of the total weight of high-sulfur coal gangue and shale. %, to obtain brick-making materials.

Embodiment 3
[0037] All the limestone is crushed to pass through a 120-mesh sieve, and the particle size is below 0.125 mm. The carbide slag is mixed with the crushed limestone at a mixing ratio of carbide slag:limestone=2:1, and then stirred evenly to obtain a sulfur-fixing agent. Among them, the portion of the calcium carbide slag with a particle size of 10-50 μm accounts for 90% of the total weight of the carbide slag.
[0038] Fully mix high-sulfur coal gangue (with a sulfur content of 5.24%) and shale at a weight ratio of 30% and 70% respectively, and then pulverize them to a size below 2mm. 75% of the total weight of the shale, and the calorific value of the mixed material is 400kcal / kg; adding a sulfur fixation agent in an amount of 7% of the total weight of the high-sulfur coal gangue and shale to obtain a brick-making material.
[0039] Add water to the brick-making material and stir evenly. The amount of water added is 12% of the weight of the brick-making material. After stirrin...
