Embodiment 1
[0030] Such as Figures 1 to 3 As shown, a kind of manufacture method of sulfuric acid is provided, comprises the following steps:
[0031] Step 1. Furnace gas generation: After entering the air filter, the air is pressurized by the main fan, then enters the drying tower to remove part of the water, and then mixes with the acid gas containing hydrogen sulfide at a pressure of 0.06MPa and passes through the 0.8MPa high-pressure pump and sulfur gun mechanical mist The liquefied liquid sulfur is sent to the incinerator for mixed combustion to generate SO 2 The temperature of mixed furnace gas and water gas is 1100 ℃, SO in the mixed furnace gas 2 Concentration is 8%, NO x The content is 600mg / Nm 3 ;
[0032] Among them, the content of hydrogen sulfide in acid gas containing hydrogen sulfide is 80%, the content of S in liquid sulfur is 99.5%, and the addition amount of liquid sulfur and acid gas containing hydrogen sulfide is 1:1.5 based on the mass ratio of sulfur content;

Embodiment 2
[0040] Such as Figures 1 to 3 As shown, a kind of manufacture method of sulfuric acid is provided, comprises the following steps:
[0041] Step 1. Furnace gas generation: After entering the air filter, the air is pressurized by the main fan, then enters the drying tower to remove part of the water, and then mixes with the acid gas containing hydrogen sulfide at a pressure of 0.06MPa and passes through the 0.8MPa high-pressure pump and sulfur gun mechanical mist The liquefied liquid sulfur is sent to the incinerator for mixed combustion to generate SO 2 The temperature of mixed furnace gas and water gas is 1000 ℃, SO in the mixed furnace gas 2 Concentration is 6%, NO x The content is 500mg / Nm 3 ;
[0042] Among them, the hydrogen sulfide content in the acid gas containing hydrogen sulfide is 75%, the S content in the liquid sulfur is 99.3%, and the addition amount of liquid sulfur and acid gas containing hydrogen sulfide is 1:2 based on the mass ratio of the respective sul...
Embodiment 3
[0050] Such as Figures 1 to 3 As shown, a kind of manufacture method of sulfuric acid is provided, comprises the following steps:
[0051] Step 1. Furnace gas generation: After entering the air filter, the air is pressurized by the main fan, then enters the drying tower to remove part of the water, and then mixes with the acid gas containing hydrogen sulfide at a pressure of 0.06MPa and passes through the 0.8MPa high-pressure pump and sulfur gun mechanical mist The liquefied liquid sulfur is sent to the incinerator for mixed combustion to generate SO 2 The temperature of mixed furnace gas and water gas is 1200 ℃, SO in the mixed furnace gas 2 Concentration is 10%, NO x The content is 600mg / Nm 3 ;
[0052] Among them, the content of hydrogen sulfide in acid gas containing hydrogen sulfide is 85%, the content of S in liquid sulfur is 99.7%, and the addition amount of liquid sulfur and acid gas containing hydrogen sulfide is 1:1 based on the mass ratio of sulfur content;
