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 loine pressure transmitter measurement apparatus 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 test of the pressure transmitter 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 transmitter, it is impossible to the pressure parameter of accurate feedback lime stone slurry, thus cannot the most effectively control
Slurry pressure, hypertonia will be transfer pipeline over loading, is susceptible to fault, and it is possible to cause and entered by pipeline
The lime stone slurry concentration on absorption tower is far longer than the SO entering absorption tower2Concentration, too much lime stone slurry can be taken by flue gas
Taking demister to, the resistance that results in blockage increases, and air-introduced machine power consumption increases, and the soot emissions entering chimney exceed standard, and make desulfurization system
System can not meet minimum discharge and system stable operation.And the too small desulfurization pipeline that the most easily blocks of pressure, it is also possible to cause for slurry
Deficiency, can reduce desulfuration 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 anti-blocking desulfurization loine pressure transmitter of a kind of band flushing water and measures
Device, by installing flushing water Anti-blocking structure, and adjusts relative dimensions parameter, enables devices to accurately measure stone in desulfurization pipeline
The force value of lime stone serosity, and long time stability run, with meet to 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 by pipeline
The lime stone slurry entering desulfuration absorbing tower will not exceed standard；It is also possible to prevent that pressure is the least cannot obtain preferable desulfurized effect.
For reaching above-mentioned purpose, the concrete technical scheme that this utility model is taked is:
The desulfurization loine pressure transmitter measurement apparatus that a kind of band flushing water is anti-blocking, including:
Connecting a probe tube of described desulfurization pipeline, less than 2.5 times of its a length of desulfurization pipeline caliber, its caliber is desulfurization pipe
0.35-0.8 times of road caliber；

Further, 1-2.5 times of a length of desulfurization pipeline caliber of described probe tube.
Further, described flushing water Anti-blocking structure includes the wash tub pipe connecting desulfurization channel interior, on described wash tub pipe
One flushing water control valve is set.
Further, described wash tub pipe one flushing water outlet with the interface of described probe tube and described desulfurization pipeline between away from
From less than 0.8 times of desulfurization pipeline caliber.
By taking technique scheme, by adjusting dimensional structure, enable devices to accurately measure limestone slurry in desulfurization pipeline
The force value of liquid, ensures the requirement of pressure transmitter measurement device precision, and after measurement, the data precision of feedback is high and stable, protects
Barrier desulfurization minimum discharge precision requirement.And rinsed by the timing of flushing water Anti-blocking structure, the steady running of ensuring equipment.
