Description
Technical field
The utility model is related to fire coal boiler fume treatment technology more particularly to a kind of gaseous oxidation collaboration absorption flue gas are more
Pollutant purification device.
Background technology
A large amount of pollutant (such as SO that fuel combustion process releases2, NOx, heavy metal, bioxin, VOCs, PM etc.) be ring
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
Desulphurization denitration, (NH3-SCR) denitration of NH3 selective catalytic reduction is widely used in coal-burning power plant both at home and abroad at present and wet flue gas is de-
The technical combinations of sulphur (WFGD).SCR technology denitration efficiency is high, stable, but there are still the mistakes of catalyst
Higher dust in flue gas under secondary pollution caused by clean, reducing substances (such as ammonium hydroxide etc.) are revealed, and high grey deployment scenarios
The problems such as particle easily causes the abrasion of catalyst, blocks.Meanwhile 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, but all types of industries furnace flue gas temperature is relatively low and wave
Dynamic range is big, and pollutant concentration fluctuating range is big and complicated component, catalyst poisoning is easily caused, using wet flue gas desulfurizer
Though the technical combinations of desulfurization and the selective catalytic denitrification process have higher denitrification efficiency, it is not suitable for steel sintering and portion
Divide the processing of the furnace flue gas such as Industrial Boiler.Also, all types of industries stove is introduced separately into desulphurization denitration technology often cause be
It unites numerous and jumbled, the problems such as taking up a large area, investing the problems such as operating cost is high or even some old units even there are difficult arrangements.
Therefore, China is badly in need of a kind of applied widely, desulfurization and denitrification integral, can even synchronize removal multiple pollutant
Flue gas multiple pollutant purifier, can low cost, efficient simultaneous SO_2 and NO removal and product recycling profit may be implemented
With.
Utility model content
The utility model aim is for current various flue gas desulfurization and denitrification technical functionalities are single, investment is big, operating cost
High, by-product is worth low disadvantage, provides a kind of strong absorbability of the strong oxidizing property and desulfurizing tower of combination ozone, and using new
Type high-efficient wet-type electric precipitator carries out final advanced treating, realizes multinomial pollutant (such as SO2, NOx, heavy metal, bioxin,
VOCs, PM etc.) synchronous purification a kind of gaseous oxidation collaboration absorb flue gas multiple pollutant purifier.
NOx during steel works sintering is mainly derived from the combustion of fuel in sintering process (igniter fuel and sintering fuel)
It burns, the concentration about 300mg/Nm of usual NOx3Left and right.The nitrogen oxides generated in combustion process is mainly NO and NO2, it is referred to as
NOx.Sintering belt experiment shows that the main component of nitrogen oxides of exhaust gas is NO.NO accounts for 95% or more, NO in usual NOx2It is small
In 5%.
Plasma ozone denitration technology is acted on using the advanced oxidation of active group, and wherein main component ozone is as one
Kind strong oxidizer, readily can be oxidized to NO by NO2、NO3、N2O5Etc. high-valence states be easy to absorbed compound.Then rear
The desulfurizing tower of section is absorbed, and reaches removing purpose.
(1) generation of active group.The generation of denitration activity group derives from high-pressure discharge principle, and gas medium exists
Under action of high voltage, gas medium is made to ionize.Wherein main component is ozone.When using air as air source, plasma
Generator dissociates the O in air2、N2、H2O equimoleculars generate plasma free radical：O2、N2、H2O→OH、O、N、HO2、O3、e。
When using oxygen as air source, plasma generator dissociates O2Molecule generates plasma free radical：O3、O2, O, e isoreactivity from
By base.Ozone plasma generator living radical includes O3、O2, O, OH etc., wherein main active substances are with O3Based on, if
It counts parameter quantitative and presses O3Meter.
(2) oxidation of NO.Active group O3、O、OH、HO2, N, e etc. react with NO：
NO+O3→NO2+O2
NO2+O3→NO3+O2
NO2+NO3→N2O5
NO+NO3→2NO2
NO+O+M→NO2+M
NO+OH→HNO2
NO2+OH→HNO3
NO+N*→N2+O
NO+N2*→N2O+N。
The main composition of NOx is NO in flue gas, and NO is insoluble in water, and the NO of high-valence state2、N2O5Etc. water-soluble generation
HNO2And HNO3, dissolved absorbability greatly improves.The mechanism is consistent with check data result.
With other chemical substances such as CO, SO2Etc. comparing, NO can be soon by ozone oxidation, therefore ozone oxidation is to NO
With very high selectivity.NOx after oxidation is converted to be dissolved in the ionic compound of aqueous solution so that oxidation reaction more adds
Entirely, NOx is irreversibly stripped of without generating secondary pollution.
(3) it absorbs.The NO generated after being aoxidized2、N2O3、N2O5Etc. high-valence states nitrogen oxides be only absorbed by the water generation ammonium nitrate
HNO3, for the ammonia process of desulfurization, NH is generated in absorbing slurries4NO3.For calcium method desulfurization, calcium nitrate Ca is generated in absorbing slurries
(NO3)2.Through peroxidization, ozone is consumed by reaction, and remaining excessive ozone can decompose in spray column.In addition to NOx
Except, some heavy metals such as mercury and other heavy metal contaminants are also aoxidized by ozone simultaneously.Dust or solid particle in flue gas
Object does not interfere with the removal efficiency of NOx, does not generate secondary pollution.Compared with desulfurization product, denitration absorption product quantity is seldom, no
The physical property of desulfurization ash product can be had an impact.
