Description
Technical field
The utility model relates to a kind of flue gas desulfurization devices.
Background technique
In Wet Fgd By Limestone system, desulfurization slurry is under slurry circulating pump power drive, desulfurization slurry warp
It is sprayed by desulfurization slurry pond-pipeline-slurries pump-pipeline-spray equipment nozzle, the former flue gas of higher temperature and desulfurization are starched
Liquid mixes and passes through heat and mass transfer process, and the partial moisture evaporation in desulfurization slurry, flue-gas temperature reduces humidity and increases so that satisfying
With SO thereinn(sulfur dioxide/sulfur trioxide) and dust etc. be removed and enter desulfurization slurry in, it is processed after flue gas
Discharge desulfurizing tower enters atmosphere.After desulfurization slurry is concentrated, returns to slurry pool and continue cycling through use.In order to keep desulfurization slurry
Desulphurizing ability needs constantly to supplement new lime stone slurry.As desulfurization slurry is recycled for multiple times, from being used to prepare
The chloride ion in chloride ion, lime stone in water used in desulfurization slurry, chloride ion in former flue gas etc., in desulfurization slurry not
Disconnected enrichment, concentration are continuously improved.It (should not generally be higher than 20000mg/l) when the chlorine ion concentration in desulfurization slurry is excessively high, take off
The corrosivity of sulphur slurries will be sharply increased, and aggravate to the metallic material corrosion of desulphurization system, while can also reduce desulfuration efficiency.For
It solves these problems, when chlorine ion concentration is higher than normal value in the desulfurization slurry in desulfurization slurry pond, needs to starch desulfurization
External discharge is separated containing the water of chloride ion in part in liquid.In order to reduce the influence to external system, need this part
It is handled, to reduce the particulate matters such as suspended matter therein.Routine techniques passes through past water using dosing techniques such as three headers at present
Middle addition flocculant or other medicaments, make the particulate matters flocculation sedimentations such as suspended matter, the desulfurized gypsum in water, and removing suspended matter takes off
The water purification of the particulate matters such as sulphur gypsum is exhausted from system, such as to discharge outside factory or enters other systems.The suspended matter to precipitate
Equal particulate matters form sludge, utilize sludge discharge or press filteration system discharge system.The main problem of this technology is: (1) system

In enclosing.That is, the moisture into the moisture and outflow desulfurizing tower of desulfurizing tower should keep centainly balancing.Currently carry out
In plume control, desulfurizing tower outlet temperature and humidity need to keep reduced levels, so that the flue gas of outflow desulfurizing tower is taken away
Moisture reduce, so that the water balance to desulphurization system brings difficulty.Even if reducing the process water of desulfurizing tower as far as possible sometimes
Dosage still cannot maintain the water balance in desulphurization system.For this reason, it may be necessary to extract certain amount and quality from desulfurization slurry
Water.However, there is presently no fairly simple, economic methods.
If simply the slurries in desulphurization system are discharged, on the one hand will cause slurries cannot be fully utilized, and cause
Slurries and water resource waste, on the other hand due to the slurries do not meet discharge standard and can not direct emission, need further to locate
Reason, causes processing cost to increase.
It utilizes if the moisture in slurries distilled by way of flash distillation, is recycled in desulfurizing tower once again
Water content declines in slurries, and sulphur-containing substance and various pollutants concentration increase, and pH value decline reduces desulfurization and dedusting effect, and
And various material concentrations increase, and cause spray system injection uneven, atomizing effect reduces, and influences desulfurization, dedusting and other effects.And
And on-condensible gas is extracted out by vacuum pump in flash process, also results in other environmental pollution.Moreover, flash distillation plant manufactures
It is at high cost, it takes up space huge, operation energy consumption itself is big.
In addition, being generally required preposition to desulfurization wastewater progress in the desulfurization wastewater zero-emission work currently carried out
Processing mainly uses dosing flocculation sedimentation technique at present, there is a problem of same as three header techniques.
