Description
Technical field
This utility model relates to environmental technology field, particularly relates to Wet Flue Gas Desulfurization Technology field, is specifically related to a kind of band and rinses
The desulfurization pipeline tester of pressure gauge on the spot that water is anti-blocking.
Background technology
State Development and Reform Commission prints and distributes " coal electricity energy-saving and emission-reduction upgrading and transformation action plan (2014-2020) " atmospheric pollution of keeping under strict control
Thing discharges.Newly-built Thermal generation unit (be contained in and build the unit having included country's construction of fire and electricity planning with project in) answers synchronized construction first
Forward (FWD) flushing water, denitration and dust removal installation, must not arrange gas bypass passage.Eastern region (Liaoning, Beijing, Tianjin,
11 provinces and cities such as Hebei, Shandong, Shanghai, Jiangsu, Zhejiang, Fujian, Guangdong, Hainan) newly-built Thermal generation unit atmospheric pollution
Thing concentration of emission basically reach gas turbine group emission limit (i.e. under the conditions of benchmark oxygen content 6%, flue dust, sulfur dioxide, nitrogen
Emissions of oxides concentration is respectively no higher than 10,35,50 milligrams/cubic metre).Middle part (Heilungkiang, Jilin, Shanxi, peace
8 provinces such as emblem, Hubei, Hunan, Henan, Jiangxi) new-built unit is in principle close to or up gas turbine group emission limit, bulging
Encourage west area new-built unit close to or up gas turbine group emission limit.Support that synchronization is carried out atmosphere pollution combination and cooperation and taken off
Remove, reduce the pollutant emissions such as sulfur trioxide, hydrargyrum, arsenic.
Along with China's economic development, electricity needs persistently increases, haze long lasting effect, controls PM2.5 and refer to agenda.
Local government, electric power enterprise propose " minimum discharge ", " near-zero release ", the construction of " reaching combustion engine discharge standard " one after another or change
Make requirement." minimum discharge " technology, scientific guidance Thermal Power Generation Industry sustainable development ultra-clean is discharged.
In this context, in tradition flue gas desulphurization system, configured and the most no longer adapted to existing relevant regulations or requirement.
Such as, at the most manometric test in desulfurization pipeline, pipeline does not has effective clogging-preventing measures, easily blocks, and once occurs stifled
It is malfunctioning that plug may result in Pressure gauge on the spot, thus cannot accurately control the pressure of lime stone slurry, and hypertonia will be conveying pipe
Road over loading, is susceptible to fault, and it is possible to cause the lime stone slurry concentration by pipeline entrance absorption tower to be far longer than
Enter the SO on absorption tower2Concentration, too much lime stone slurry can be carried to demister by flue gas, and the resistance that results in blockage increases,
Air-introduced machine power consumption increases, and the soot emissions entering chimney exceed standard, and makes desulphurization system can not meet minimum discharge and system stability fortune
OK.And the too small desulfurization pipeline that the most easily blocks of pressure, it is also possible to cause, for slurry deficiency, desulfuration efficiency and effect to be reduced, with
Sample affects qualified discharge.
Utility model content
