Embodiment 1
[0036] A kind of acid production process is characterized in that, comprises the steps:
[0037] Step S1, waste acid treatment: the waste sulfuric acid by-product of the refinery is atomized to form acid mist by using a combination of high-pressure pump conveying mechanical atomization and compressed air assisted atomization; the quality of the waste sulfuric acid is 100%. The sub-concentration is 80%; the particle size of the acid mist is 60um.
[0038] Step S2, treatment of sulfur-containing minerals: pulverize the sulfur-containing minerals, then use a detergent to clean them in an ultrasonic cleaner at 40-50°C for 1-2 hours, rinse them with water, and dry them at 80°C until they reach a constant weight; The sulfur-containing mineral is pyrite;
[0039] Step S3, preparation of mixed furnace gas: the sulfur-containing minerals produced in step S2 are oxidized and burned to obtain furnace gas, which is cooled and dusted in turn, and then passed through an empty tower, a pack...
Embodiment 2
[0047] A kind of acid production process is characterized in that, comprises the steps:
[0048] Step S1, waste acid treatment: the waste sulfuric acid by-product of the refinery is atomized to form acid mist by using a combination of high-pressure pump conveying mechanical atomization and compressed air assisted atomization;
[0049] Step S2, treatment of sulfur-containing minerals: pulverize the sulfur-containing minerals, and then use a detergent to clean them in an ultrasonic cleaner at 42°C for 1.2 hours, rinse them with water, and dry them at 83°C until they reach a constant weight;
[0050] Step S3, preparation of mixed furnace gas: the sulfur-containing minerals produced in step S2 are oxidized and burned to obtain furnace gas, which is cooled and dusted in turn, and then passed through an empty tower, a packed tower, a dynamic wave scrubber and an electric furnace gas in sequence. Demister, purify high-concentration sulfur-containing gas; and mix the obtained high-con...
Embodiment 3
[0062] A kind of acid production process is characterized in that, comprises the steps:
[0063] Step S1, waste acid treatment: the waste sulfuric acid by-product of the refinery is atomized to form acid mist by using a combination of high-pressure pump conveying mechanical atomization and compressed air assisted atomization;
[0064] Step S2, treatment of sulfur-containing minerals: pulverize the sulfur-containing minerals, and then use a detergent to clean them in an ultrasonic cleaner at 45°C for 1.5 hours, rinse them with water, and dry them at 85°C until they reach a constant weight;
[0065] Step S3, preparation of mixed furnace gas: the sulfur-containing minerals produced in step S2 are oxidized and burned to obtain furnace gas, which is cooled and dusted in turn, and then passed through an empty tower, a packed tower, a dynamic wave scrubber and an electric furnace gas in sequence. Demister, purify high-concentration sulfur-containing gas; and mix the obtained high-con...
