Description
Technical field
The utility model belongs to fume treatment technical field, and in particular to a kind of Novel flue gas desulfurization removes white dust-extraction unit.
Background technique
A large amount of pollutants (such as SO2, NOx, heavy metal, dioxin, VOCs, PM) that fuel combustion process releases are rings
The main reason for border is worsening, and the purification of flue gas is to control one of the effective way of disposal of pollutants after burning.For flue gas
Desulfurization, former (NH3-SCR) denitration of NH3 selectivity recall and wet process of FGD is widely used in coal-burning power plant both at home and abroad at present
(WFGD) technical combinations.Though technical combinations desulfuration efficiency with higher is not suitable for steel sintering and part industry
The processing of the furnace flue gas such as boiler, the reason is that such flue-gas temperature is lower and fluctuation range is big, pollutant concentration fluctuates width
Big and complicated component is spent, catalyst poisoning is easily caused.Also, independent desulfurization technology often causes, and system is numerous and jumbled, occupied area
Greatly, the problems such as investment operating cost is high.After Thermal Power Generation Industry implements in full minimum discharge transformation, all types of industries stove will become
The most important air pollution emission source in China.
Flue gas after desulfurization is the pollutants such as saturated flue gas and micro aerosol, it appears that discharge is " white cigarette ", in order to
Compare and completely remove harmful substances in flue gas, including reduces nitrogen oxides, sulfide, various soot dust granule objects, aerosol, ultra-fine
The discharge of grain of salt crystals object reduces the generation of chimney rain and meets the visual appearance of people, also needs that " flue gas is de- after desulfurization
It is white ", but existing flue gas takes off whitening method, and system structure is complicated, needs larger in lifting temperature, and energy consumption is high, is unfavorable for energy conservation and subtracts
Row.Wet desulphurization take off it is white, can not only eradicate haze pollution, moreover it is possible to be realized with a low cost environment protection standard, ultralow near-zero release, Nian Jieshui
Tens tons of potentiality, the contradiction for solving environment and development can be taken into account.
Utility model content

Row is continual and steady and at low cost, desulfurization can be realized, except white and dedusting function using set of device.
The technical scheme adopted by the utility model is a kind of Novel flue gas desulfurization removes white dust-extraction unit, including pass through pipe
Electric precipitator, blower, desulfurizing tower, sulphur removal case, heat exchanger and the drier that road is sequentially connected, the electric precipitator are provided with cigarette
Gas entrance, the drier are provided with exhanst gas outlet.
Preferably, the desulfurizing tower top is provided with metal net layer, is evenly arranged with left water conservancy diversion in the desulfurizing tower tower body
Plate and right deflector, the left deflector and right deflector interval are arranged, and are uniformly arranged on the left deflector and right deflector
There is spray head.
It is furthermore preferred that spray medicament is sodium hydroxide solution in the spray head.
Even more preferably, active carbon is filled in the sulphur removal case.
Even more preferably, quartz sand, gravel, haydite, medical stone, activated alumina ball are filled in the drier
One of with fiber bundle media.
Compared to the prior art, the utility model has the advantages that a kind of Novel flue gas desulfurization removes white dust-extraction unit,
Including electric precipitator, blower, desulfurizing tower, sulphur removal case, heat exchanger and the drier being sequentially connected by pipeline, using electric precipitation
Device removes the dust in flue gas, carries out first time processing to the sulfide in flue gas using desulfurizing tower, passes through the work in sulphur removal case
Property carbon remove remaining sulfide in flue gas, reducing flue-gas temperature by heat exchanger makes water recovery, using drier into one
Step removes moisture in flue gas, and package unit is simple, operation is continual and steady and at low cost, and desulfurization can be realized using set of device and remove
White and dedusting function.
