Description
Technical field
The present invention relates to a kind of flushing water collecting device, especially discloses a kind of absorption tower with primary defrosting function and remove
Day with fog rinses water collecting device, applies in coal-burning power plant's wet process of FGD.
Background technique
In the existing fired power generating unit in China, coal unit accounts for about 93%, and environmental pollution caused by fire coal specifically includes that harmful gas
Body (SO2, NOX), solid slag (flyash, furnace bottom ash, Desulphurization), wherein SO2 is one of main atmosphere pollution.
About nearly hundred kinds of sulfur removal technology developed at present, but really only more than 10 kinds of realization industrial application.
It puts into operation or just in the desulphurization system of Program Construction, Wet Flue Gas Desulfurization Technology accounts for 80% or so.Wet Flue Gas Desulfurization Technology is because of it
Cost of investment is low, desulfuration efficiency is high is widely used by power plant, but its water consumption is higher, it has also become the main water system of power plant.Cause
This solves the problems, such as that desulphurization system water balance is one of important topic of Wet Flue Gas Desulfurization Technology.
Desulphurization system water balance refers into absorption tower water (mainly mist eliminator flushing water, former flue gas contained humidity, lime
Stone carries water for slurry) both absorption tower water (mainly neat stress is evaporated to carry and be drained outside water and waste water) holding dynamic is flat with taking out of
Weighing apparatus.Wherein mist eliminator flushing water is the main source of desulphurization system water inlet.
Desulphurization system water balance is mainly realized by controlling other waters into system in actual operation, such as: control
System enters the flue-gas temperature on absorption tower, control mist eliminator flushing water, reduces or prevent the process water for being directly discharged into system and work
Industry water reduces the equipment start-stop frequency to reduce equipment pipe washing water quantity, reasonable control belt filter cloth washing water, prevent to rinse
Leakage etc. in penstock.
In recent years, China's most area persistently meets with haze, and country requires Air Pollutant Emission control further
It improves, new fossil-fuel power plant atmospheric pollutant emission standard (GB13223-2011) was formally implemented on January 1st, 2012.New discharge
Standard requires all to be greatly improved to flue dust, sulfur dioxide, nitrogen oxidation emission control.The positive respective country number in each department
It calls together, formulates and carry out minimum discharge standard, after data statistics shows coal-burning power plant's minimum discharge desulfurizing fly ash, desulphurization system
Mist eliminator flushing water will by about one time than increasing before transformation.The low low temperature electrostatic dedusting technology used in minimum discharge simultaneously reduces
The flue-gas temperature for entering absorption tower, make to evaporate and the discharge reduction that consumes, the rinse water arrangement that Wet-type electric dust removal system uses
With capture water installations, the above factor to desulfurization level weighing apparatus control bring greater impact, processing control it is bad will increase it is de-
Sulphur system water consume, while generating a large amount of waste water.
Because mist eliminator flushing water is the main source of desulphurization system water inlet, and existing mist separator of desulfurization flushing water is all one
Secondary property flushing is directly entered absorption tower, in order to control desulphurization system water balance, it is necessary to control mist eliminator flushing water, demister punching
Leaching requirement reduction will lead to the decline of demister blade cleaning, in fact it could happen that demister fouling and blocking, or even deformation, collapsing,
Larger negative effect is brought to unit air and gas system.
Summary of the invention
