Embodiment 1
[0032] Embodiment 1: a kind of activated carbon production technology that uses granular bituminous coal and hematite lump ore, its main production steps are:
[0033] (1) Use 5-20mm bituminous coal particles, wherein the volatile fraction of bituminous coal is 25%, and the fixed carbon is 45%;
[0034] (2) Use 5-30mm hematite natural lump ore, of which the total iron is 58%;
[0035] (3) mix bituminous coal particles and natural lump ore in a weight ratio of 60:100;
[0036] (4) The distributing facility sends the above-mentioned mixed material into the multi-chamber vertical furnace, and runs from top to bottom. The temperature of the carbonization section is 300-800°C, and the temperature of the activation section is 1000-1100°C; the residence time of the charge in the activation section is 10-12 hours; the charge is finally discharged from the lower cooling area to 50-100°C;
[0037] (5) Carry out magnetic separation and separation of mixed material etc., receive gac and...
Embodiment 2
[0038] Embodiment 2: a kind of production technology that uses pulverized coal bituminous coal and magnetite cold-pressed pelletized activated carbon, its main production steps are:
[0039] (1) Use bituminous coal powder less than 50 mesh and content greater than 90%, wherein the volatile content of bituminous coal is 25%, and the fixed carbon is 45%. Bituminous coal is extruded into briquette;
[0040] (2) use Magnetite cold-pressed pellets, of which total iron is 68%;
[0041] (3) Mixing briquette and pellet weight ratio 50:100;
[0042] (4) The distributing facility sends the above-mentioned mixed material into the multi-chamber vertical furnace, and runs from top to bottom. The temperature of the carbonization section is 300-800°C, and the temperature of the activation section is 1000-1100°C; the residence time of the charge in the activation section is 10-12 hours; the charge is finally discharged from the lower cooling area to 50-100°C;
