Description
Technical field
The invention belongs to fume treatment technical fields, specifically, being related to a kind of for purifying the life of amino acids production flue gas
Change method.
Summary of the invention
During fermentative preparation of amino acids, a large amount of boiler smokes can be generated.Boiler smoke is the mixing of gas and flue dust
The main reason for object is pollution residential block atmosphere.The ingredient of flue gas is very complicated, in gas include sulfide, carbon compound and
Oxynitrides etc., flue dust include the ash content of fuel, coal grain, oil droplet and high-temperature split product etc..Therefore flue gas is to environment
Pollution is the combined pollution of a variety of poisonous substances.Flue dust is related to the harmfulness of human body and the size of particle, generates harm to human body
It is mostly floating dust of the diameter less than 10 microns, it is especially maximum with 1-2.5 microns of floating dust harmfulness.Flue dust to the pollution of air with
Meteorological Conditions are close, and wind, atmospheric stability, turbulent flow etc. and the state of air pollution are in close relations, furthermore photochemistry, bioid
Also have certain influence to the pollution of flue gas.To human body when endangering the composition on the one hand depending on polluter, concentration, continuing
Between and site of action, on the other hand depend on human body sensibility.Flue gas concentration height is can to cause acute poisoning, shows as cough
It coughs, pharyngalgia, asthma uncomfortable in chest, headache, eyes stung etc., serious person can be dead.Most commonly slow poisoning causes stimulation to breathe
Road mucous membrane leads to chronic bronchitis etc..
Currently, more mature method generally use multisystem independent removing sulfuldioxide (it is so-called it is independent removing refer to denitration with
Desulfurization substep carries out), which can reach the various pollutants in flue gas higher removal rate, but flue gas purification system is huge
Miscellaneous, land occupation is more, and the investment of equipment and operating cost are high, and the high-temperature flue gas of difficult 600 DEG C of direct purification or more.For this purpose, people
Have studied the synchronized desulfuring and denitrifying technology of flue gas.
Synchronized desulfuring and denitrifying technology mainly has dry method, wet process and bioanalysis.Impulse electric corona method, Electron Beam Irradiation and dry type
Catalysis method is the Typical Representative in dry desulfurization denitration, although dry method has advantage without secondary pollution etc., there is also
The problem of processing cost is high, investment is big and NH_3 leakage etc..Study more mature in Wet technique is calcium-base absorbing agent
Catalytic oxidation, the method are a kind of technologies to grow up on the basis of adding calcium wet desulfurizing process, although having technique letter
The advantages that single, but the secondary pollutions such as by-product calcium sulfate and flue gas need the defect of cooling processing that can not avoid.Bioanalysis
It is the method that SO2 and NOX in flue gas is handled using microorganism, which has the advantages that invest low with operating cost etc..
In recent years, thin using the desulfurization microorganism progress desulfurization being separated to from different niches, including photosynthetic sulphur both at home and abroad
Bacterium, Thiobacillus etc., most mature representative bacterium is T.f bacterium (Thiobacillus ferrooxidans), while having carried out the mechanism of bacterial desulfurization
Research.The states such as Holland, Germany, Japan, the U.S. achieve some successes in terms of biological desulphurization, in terms of some biological desulphurizations
Reported in literature, as 1) German patent is to disclose in the document of DE102005025040 by biogas and from photosynthesis
Oxygen rich gas mixed in biochemical de-sulfur device after biochemical de-sulfur；2) Japanese Patent number is the " natural pond of JP2004135579
It in gas biological desulphurization system ", discloses and is inversely contacted by nitrification liquid with biogas, absorb, aoxidize hydrogen sulfide in biogas；3) day
This patent number be JP2003062421 " bio-desulfurization device " in, disclose by aerobic aeration sludge spray into desulfurizing tower in contain
The reverse contact desulfuriation of sulphur gas, desulfurization sludge, which passes back into, carries out regeneration activating in aeration tank.
How the industrial energy consumption of flue gas desulfurization and denitrification to be minimized using biochemical technology, and simple possible environmental protection is without dirt
Dye is prior art technical problem urgently to be resolved.
