The utility model provides a realize near zero emission's two segmentation dual cycle SOx/NOx control devices, include: an one -level denitrification facility, an one -level desulphurization unit and a second grade desulfurization denitrification facility that flue gas flow set gradually follow. Wherein, at second grade SOx/NOx control device installation ozone grid. The flue gas after one -level denitration and one -level desulfurization, spout into ozone in to the flue gas through the ozone grid, with remaining sulfur dioxide and nitrogen oxide oxidation easily by the absorptive higher oxide of solution with chenging, the realization of the independent spraying system of rethread second grade is to including sulphur with including nitrogen oxide's absorption. It contains sulphur and nitrogenous pollutant near zero emission level to reach coal -fired flue gas. |
