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 probe of PH analytical table does not has effective clogging-preventing measures, easily blocks, and once occurs blocking to may result in PH analytical table
Malfunctioning, thus cannot accurately control the concentration of lime stone slurry, excessive concentration will result in the Calx being entered absorption tower by pipeline
Stone concentration of slurry is far longer than the SO entering absorption tower2Concentration, too much lime stone slurry can be carried to demister by flue gas,
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 meet super
Low emission and system stable operation.And too low desulfuration efficiency and the effect of reducing of concentration, affect qualified discharge equally.

Amount device, by installing flushing water Anti-blocking structure, and adjusts circulation groove structural parameters, enables devices to accurately measure limestone slurry
The pH value of liquid, and long time stability operation, 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 enter desulfurization by pipeline and inhale
The lime stone slurry receiving tower will not exceed standard；Be also possible to prevent that lime stone slurry concentration is too low or flow less cannot obtain the most de-
Sulfur effect.
For reaching above-mentioned purpose, the concrete technical scheme that this utility model is taked is:
