Example Embodiment
[0013] Example 1 of the present invention: a method of producing high concentration sulfur dioxide gas, figure 1 As indicated, the high-temperature sulfur dioxide to the burning produced by the burning furnace is cooled, and after the flue gas is used through the flue gas fan, the pipe is returned to the front end of the production system and the air mixed into the burning furnace together, and the mixed gas is mixed. The sulfur dioxide gas concentration in the concentration of sulfur dioxide is ≤ 5.36%, and the remaining sulfur dioxide smile gas enters the downstream process, and the liquid sulfur is fed into the incinerabilibulfur furnace under the action of the liquid sulfur. This loop reciprocates.
[0014] The high-temperature sulfur dioxide to the burning of the burning furnace is first caught in the heat boiler to 310 ° C ~ 330 ° C, and enter the provincial coal armor to cool down to 130 ° C ~ 150 ° C, and some of the sulfur dioxide to the saulinated smile to return to the ...
