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 pipeline at densimeter sampling and measuring in desulfurization pipeline does not has effective clogging-preventing measures, easily blocks, and once occurs stifled
It is malfunctioning that plug may result in densimeter, thus cannot accurately measure serum density, and then the concentration of uncontrollable lime stone slurry, dense
Spend height and will result in the SO2 concentration being far longer than entrance absorption tower by the lime stone slurry concentration on pipeline entrance absorption tower, mistake
Many lime stone slurries can be carried to demister by flue gas, and the resistance that results in blockage increases, and air-introduced machine power consumption increases, and enters cigarette
The soot emissions of chimney exceed standard, and make desulphurization system can not meet minimum discharge and system stable operation.And concentration too low can reduce de-
Sulphur efficiency and effect, 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 densimeter measurement device that a kind of band flushing water is anti-blocking,
By installing flushing water Anti-blocking structure, and adjust relative dimensions parameter, enable devices to accurately measure the density of lime stone slurry,
And long time stability runs, to meet the water needed for desulfurization minimum discharge, lime stone slurry, gypsum slurries supplies consumption
Accurately control.Avoid unnecessary waste, cut operating costs；Simultaneously, it is ensured that entered the Calx of desulfuration absorbing tower by pipeline
Stone serosity will not concentration over-standard；It is also possible to prevent that concentration is too low cannot obtain preferable desulfurized effect.
For reaching above-mentioned purpose, the concrete technical scheme that this utility model is taked is:
The desulfurization pipeline densimeter measurement device that a kind of band flushing water is anti-blocking, including:
A sampling line of described desulfurization pipeline is accessed at two ends, has a mid portion, and the caliber of described mid portion is described de-
1.5-2.5 times of the caliber of sulfur pipeline, more than 6 times of the caliber of a length of described desulfurization pipeline；
