Embodiment 1
[0026] A process for making acid by co-incinerating waste sulfuric acid and hydrogen sulfide, comprising the following steps:
[0027] Step (1): The waste sulfuric acid with a by-product concentration of 75% in the refinery is atomized by a combination of high-pressure pump mechanical atomization and compressed air assisted atomization to form acid mist, and the particle size of the acid mist is 20~80um;
[0028] Step (2): Mix hydrogen sulfide gas with a concentration of 30% by-product of the refinery and hot air in the swirl air inlet to make a mixed gas of hydrogen sulfide gas and hot air;
[0029] Step (3): The acid mist is sprayed into the incinerator with a waste acid spray gun, and at the same time, the mixed gas of hydrogen sulfide gas and hot air is sprayed into the incinerator with a hydrogen sulfide spray gun for incineration, cracking and reduction reaction to generate SO 2 furnace gas, the SO 2 The furnace gas enters the acid system after recovering heat from the...
Embodiment 2
[0032] A process for making acid by co-incinerating waste sulfuric acid and hydrogen sulfide, comprising the following steps:
[0033] Step (1): The waste sulfuric acid with a by-product concentration of 85% in the refinery is atomized by a combination of high-pressure pump mechanical atomization and compressed air assisted atomization to form acid mist. The particle size of the acid mist is 10~50um;
[0034] Step (2): Mix hydrogen sulfide gas with a concentration of 35% by-product of the refinery and hot air in the swirl air inlet to fully make a mixed gas of hydrogen sulfide gas and hot air;
[0035] Step (3): The acid mist is sprayed into the incinerator with a waste acid spray gun, and at the same time, the mixed gas of hydrogen sulfide gas and hot air is sprayed into the incinerator with a hydrogen sulfide spray gun for incineration, cracking and reduction reaction to generate SO 2 furnace gas, the SO 2 The furnace gas enters the acid system after recovering heat from t...
Embodiment 3
[0038] A process for making acid by co-incinerating waste sulfuric acid and hydrogen sulfide, comprising the following steps:
[0039] Step (1): 30kt / a waste sulfuric acid with a by-product concentration of 95% in the refinery is atomized by a combination of high-pressure pump transport mechanical atomization and compressed air assisted atomization to form acid mist. Fog particle size 15 ~ 60um;
[0040] Step (2): 2000Nm of hydrogen sulfide gas with a concentration of 20% by-product in the refinery 3 / h is fully mixed with hot air in the swirling air inlet to make a mixed gas of hydrogen sulfide gas and hot air; the hot air is the high-temperature furnace gas after the waste heat boiler, and the air at normal temperature and pressure is indirectly heat-exchanged to 450 through a heat exchanger ℃~600℃
[0041] Step (3): The acid mist is sprayed into the incinerator with a waste acid spray gun, and at the same time, the mixed gas of hydrogen sulfide gas and hot air is sprayed ...
