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 electromagnetic flowmeter survey device 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, the electromagnetic flowmeter in desulfurization pipeline does not has effective clogging-preventing measures, easily blocks, and once occurs blocking to may result in electricity
Magnetic flowmeter is malfunctioning, thus cannot accurately control the concentration of lime stone slurry, and excessive concentration be will result in be entered by pipeline and absorbs
The lime stone slurry concentration of tower is far longer than the SO entering absorption tower2Concentration, too much lime stone slurry can be carried to by flue gas
Demister, the resistance that results in blockage increases, and air-introduced machine power consumption increases, and the soot emissions entering chimney exceed standard, and make desulphurization system not
Minimum discharge and system stable operation can be met.And too low desulfuration efficiency and the effect of reducing of concentration, affect qualified discharge equally.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide the desulfurization pipeline electromagnetic flowmeter survey that a kind of band flushing water is anti-blocking
Device, by installing flushing water Anti-blocking structure, and adjusts relative dimensions parameter, enables devices to accurately measure lime stone slurry
Flow value, and long time stability operation, to meet the water needed for desulfurization minimum discharge, lime stone slurry, gypsum slurries thing
Material consume accurately control.Avoid unnecessary waste, cut operating costs；Simultaneously, it is ensured that enter desulfurization by pipeline and absorb
The lime stone slurry of tower will not exceed standard；It is also possible to prevent that flow is less cannot obtain preferable desulfurized effect.
