Embodiment 1
[0065] The material of the conveyor belt in this embodiment is graphite, and the length of the distillation and desulfurization zone formed by heating the middle of the belt conveyor by a gas heater is 0.8 m.
[0066] The process of antimony sulfide concentrate molten salt electrolysis fume purification and sulfur production is as follows:
[0067] The chemical composition of sulfur-containing soot A obtained by molten salt electrolysis of an antimony sulfide concentrate is as follows: the mass proportion of molten salt is 10wt%, the mass proportion of antimony sulfide is 35%, and the mass proportion of elemental sulfur is 55%.
[0068] First, adjust the thickness of soot on the conveyor belt to be 2 cm, the running speed to be 0.2 cm / s, the distillation temperature to be 600°C, and the nitrogen flow rate to be 0.1 cm / s. The condensing temperature of the first condensing tower was controlled to be 540°C and the gas flow rate was 0.05cm / s, and the temperature of the second cond...
Embodiment 2
[0070] The material of the conveyor belt in this embodiment is alumina, and the length of the distillation and desulfurization zone formed by heating the middle of the belt conveyor by a gas heater is 0.8 m.
[0071] The process of antimony sulfide concentrate molten salt electrolysis fume purification and sulfur production is as follows:
[0072] The chemical composition of sulfur-containing soot B obtained by molten salt electrolysis of an antimony sulfide concentrate is: the mass proportion of molten salt is 15wt%, the mass proportion of antimony sulfide is 27%, and the mass proportion of elemental sulfur is 58%. First, adjust the thickness of soot on the conveyor belt to be 4 cm, the running speed to be 0.4 cm / s, the distillation temperature to be 580°C, and the flow rate of nitrogen gas to be 0.2 cm / s. The condensing temperature of the first condensing tower was controlled to be 500°C and the gas flow rate was 0.1 cm / s, and the temperature of the second condensing tower w...
Embodiment 3
[0074] The continuous purification and desulfurization process test of smoke and dust was carried out with the same raw materials and parameters in the above-mentioned Example 2. After the process runs for 3 hours, the intermediate temperature condensation tower product is collected, and the proportion of antimony sulfide is 98.4wt%, the proportion of molten salt is 1.2wt%, and the proportion of elemental sulfur is 0.4wt%. The product of the second condensing tower is collected, and the proportion of antimony sulfide is 0.1 wt %, the proportion of molten salt is 0.2 wt %, and the sulfur grade is 99.7 wt %. The molten salt composition at the end of the conveyor belt is: 0.2 wt% of antimony sulfide, 0.1 wt% of sulfur, and 99.7% of molten salt.
