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 absorbing tower liquid-level measurement apparatus of water.
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 liquid level emasuring device of desulfuration absorbing tower does not has effective clogging-preventing measures, easily blocks, and once occurs blocking to may result in suction
Receive tower liquid level emasuring device malfunctioning.Thus cannot accurately control concentration and the flow of lime stone slurry, it is possible to can take off
Limestone slurry flow quantity in sulfur system is excessive or too small, it is also possible to the excessive concentration or too low of lime stone slurry occurs, these
Situation all can cause adverse consequences, such as, gypsum rain phenomenon occurs, or reduces desulfuration efficiency etc..
Further, since existing desulphurization system often ignores absorbing tower liquid-level measurement apparatus in installation position in design or installation when manufacturing
Put, the parameter such as size, mounting means, the requirement to these parameter precisions is the lowest.And therefore make absorbing tower liquid-level measurement apparatus
Optimal running effect cannot be obtained, affect accuracy of measurement, thereby result in operation cost and be greatly improved, the most also can cause and pass through
Pipeline enter the lime stone slurry on absorption tower due to cannot accurate controlled concentration, be carried to demister by flue gas, result in blockage resistance
Power increases, and the soot emissions entering chimney exceed standard, and make desulphurization system can not meet minimum discharge and system stable operation.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide the absorbing tower liquid-level measurement apparatus of a kind of band flushing water, by peace
Dress flushing water Anti-blocking structure, and adjust installation parameter, enable absorbing tower liquid-level measurement apparatus to accurately measure the liquid level of serosity, and
Long time stability runs, to meet the water needed for desulfurization minimum discharge, lime stone slurry, the essence of gypsum slurries supplies consumption
Really control.Avoid unnecessary waste, cut operating costs；Simultaneously, it is ensured that entered the lime stone slurry on absorption tower by pipeline
Will not exceed standard；It is also possible to prevent that lime stone slurry concentration is too low or flow is less cannot obtain preferable desulfurized effect.
For reaching above-mentioned purpose, this utility model adopts the technical scheme that:
A kind of absorbing tower liquid-level measurement apparatus of band flushing water, including:
Connect a measurement pipeline of the bottom on described absorption tower；
A control valve coaxially connected with described measurement pipeline；
The flushing water Anti-blocking structure coaxially connected with described control valve, including: a washing ring coaxial with described measurement pipeline,
A flushing water hole and a drain hole is offered on it；Described flushing water hole connects a wash tub pipe, and described drain hole connects an evacuated tube；
One flushing water control valve is set on described wash tub pipe, described evacuated tube arranges an exhaust-valve；
A fluid level transmitter coaxially connected with described flushing water Anti-blocking structure.
Further, the axis direction of described measurement pipeline and horizontal direction are 45-47 ° of angle.
Further, described control valve is a diaphragm valve.
Further, the flange arrangement that described control valve is sealed by a band with described measurement pipeline is connected.
Further, the two ends of described flushing water Anti-blocking structure are respectively by flange arrangement and the described control valve of two bands sealings
And described fluid level transmitter connects.
By taking technique scheme, by arranging setting angle, absorbing tower liquid-level measurement apparatus is enable accurately to measure Calx
The liquid level of stone serosity, ensures desulfurization minimum discharge precision requirement.And rinsed by the timing of flushing water Anti-blocking structure, ensure and inhale
Receive the steady running of tower liquid level emasuring device.
