Description
Technical field
The utility model relates to a kind of desulfurization emission reduction device, is specifically related to a kind of desulfurization emission reduction device reducing absorption tower and the discharge of auxiliary tower desulfurization fume.
Background technology
Along with China's economic development, electricity needs continues to increase, and haze long lasting effect, control PM2.5 refer to agenda.Local government, electric power enterprise propose one after another " minimum discharge ", " near-zero release ", " reaching combustion engine discharge standard " construction or transformation requirement." minimum discharge " technology, scientific guidance Thermal Power Generation Industry sustainable development ultra-clean is discharged.
Air Pollutant Emission of keeping under strict control that State Development and Reform Commission prints and distributes " coal electricity energy-saving and emission-reduction upgrading and transformation action plan (2014-2020) ".Newly-built Thermal generation unit (being contained in the unit built and included national construction of fire and electricity planning with project in) answers the advanced high-efficiency desulfurization of synchronized construction, denitration and dust removal installation, must not arrange gas bypass passage.The eastern region newly-built Thermal generation unit Air Pollutant Emission concentration such as (Liaoning, Beijing, Tianjin, Hebei, Shandong, Shanghai, Jiangsu, Zhejiang, Fujian, Guangdong, Hainan 11 provinces and cities) reaches gas turbine group emission limit (namely under benchmark oxygen content 6% condition, flue dust, sulfur dioxide, discharged nitrous oxides concentration is not respectively higher than 10,35,50 milligrams/cubic metre) substantially.The middle part new-built unit such as (Heilungkiang, Jilin, Shanxi, Anhui, Hubei, Hunan, Henan, Jiangxi 8 provinces) in principle close to or reach gas turbine group emission limit, encourage west area new-built unit close to or reach gas turbine group emission limit.Support that synchronously carrying out atmosphere pollution combination and cooperation removes, and reduces the pollutant emissions such as sulfur trioxide, mercury, arsenic.
Existing desulphurization system under the coal-fired sulfur content of reality reaches the condition of 3.0%, entrance sulfur dioxide (6%O
2, mark state, dry state) and concentration is 6500mg/Nm
3time, and make FGD exiting flue gas sulfur dioxide emissioning concentration lower than 200mg/Nm
3, system desulfuration efficiency reaches more than 97%.
The proposition of taking the lead of the Committee of Development and Reform of Shanxi Province and province's environmental protection Room " advances the implementation guideline of the whole province Thermal generation unit flue gas ultra-clean discharge ", in implementation guideline, Shanxi Province's Thermal generation unit flue gas ultra-clean discharge point two class standards: ultra-clean discharge standard I: nitrogen oxide (NO
x) 50mg/Nm
3, sulfur dioxide (SO
2) 35mg/Nm
3, flue dust 5mg/Nm
3, executive agent is burning raw coal generating set.Existing desulfurization equipment cannot meet sulfur dioxide (SO
2) 35mg/Nm
3emission request, therefore needs to carry out the system reform to unit.
