Description
Technical field
The present invention relates to flue gas polution control technology, inhibit mercury in specifically a kind of Limestone-gypsum Wet Flue Gas Desulfurization Process technique
The method discharged again.
Background technique
Containing trace heavy metal mercury, (mercury content in the most fire coals in China is about 0.01 in industrial fuel, particularly fire coal
~1mg/kg, averagely about 0.15mg/kg), in burning, the mercury and mercuric compounds of effumability can be released, due to
Mercury and mercuric compounds have hypertoxicity and stronger bioconcentration etc., will cause pollution to environment, this is in the world
It attracts wide attention.As consumption of coal big country, the mercury emission of coal-burning power plant is huge in China, in August, 2017, China's signature
" the Minamata pact about mercury " it is formally effective, the discharge of mercury contaminants caused by strict control is coal-fired is very necessary.
Currently, the removing control of the mercury contaminants in flue gas produced by industrial fuel, particularly fire coal, main still existing
Cooperation-removal while having the control of other flue gas pollutants, wherein Limestone-gypsum Wet Flue Gas Desulfurization Process technique is exactly an important skill
Art, in removing SO2While subsidiary property remove mercury contaminants.
Limestone-gypsum Wet Flue Gas Desulfurization Process technique can the mercury form of cooperation-removal be mainly water-soluble ion mercury contaminants.
However, containing SO in the flue gas as produced by industrial fuel, particularly fire coal2Ingredient, in wet desulfurizing process with desulfurization
Liquid, which occurs to chemically react, produces SO3 2-、HSO3 -Etc. reproducibilities ion, these reproducibility ions can be absorbed with sweetening liq
The ionic mercury of removing chemically reacts, so that the ionic mercury for absorbing sweetening liq is reduced to simple substance not soluble in water again
The Elemental Mercury of mercury, generation can be discharged into atmospheric environment with desulfurization fume, and the release phenomenon again of mercury occurs, leads to lime
Stone-gypsum wet sulfur removal technology demercuration has little effect, and the demercuration technical difficulty of industrial smoke significantly increases.
For in Limestone-gypsum Wet Flue Gas Desulfurization Process technique because ionic mercury is easily reduced discharge again caused by demercuration technology
Problem, best solution are the ionic mercury reduction for inhibiting sweetening liq to be absorbed, and it is wet could to improve limestone-gypsum in this way
The demercuration efficiency of method sulfur removal technology, this is also at common recognition in the industry.
In recent years, trying to explore research always in the industry how to effectively inhibit ionic mercury to be reduced the technology that discharges again difficult
Topic, various research achievements are appeared in the newspapers repeatly to such as a kind of " demercuration absorbing liquid " (publication number CN disclosed in Chinese patent literature
103877844, publication date on 06 25th, 2014), the technology is with mass ratio for the glyoxaline ion liquid of 9:10~20 and double
Oxygen water mixes, and using hydrogen peroxide as matrix, using glyoxaline ion liquid as reaction medium, realizes the absorption of mercury contaminants
Removing has certain inhibitory effect to ionic mercury.But the accounting of the technology intermediate ion liquid is larger, causes to prepare cost
It is expensive；In addition, there is no lime stone ingredient in the technology, it is only capable of the removing of single carry out mercury contaminants, is not used in wet process
To SO in sulfur removal technology2It is removed, will increase the implementation of wet desulfurizing process if being applied in wet desulfurizing process
Technical difficulty.
Summary of the invention
Technical purpose of the invention is: in view of the above shortcomings of the prior art, providing a kind of neither influence flue gas desulfurization
Effect, but simple and easy, economical and practical, reliable efficient can inhibit absorbed in Limestone-gypsum Wet Flue Gas Desulfurization Process technique from
Sub- mercury restores the method discharged again.
The present invention realizes that technical solution used by its technical purpose is: in a kind of Limestone-gypsum Wet Flue Gas Desulfurization Process technique
Inhibit mercury method for releasing again, the inhibition mercury again taken based on Limestone-gypsum Wet Flue Gas Desulfurization Process technique by method for releasing
Technological measure is that miaow is added with the concentration of 50~100mmol/L in the sweetening liq that temperature is 45~65 DEG C, pH value is 4~6
Azole ionic liquid, the flue gas containing mercury contaminants carry out at flue gas desulfurization via the sweetening liq containing glyoxaline ion liquid
Reason, absorbs the ionic mercury in flue gas while flue gas desulfurization processing, inhibits de- by the glyoxaline ion liquid in sweetening liq
The absorbed ionic mercury of sulphur liquid is reduced into Elemental Mercury and discharges again.
The mechanism of action of the used technical solution of the present invention is that suitable imidazole-like ionic liquid is added in sweetening liq
The ion that sweetening liq is absorbed can be efficiently complexed in body, halogen functional group (Cl or Br) contained by glyoxaline ion liquid
Mercury is present in ionic mercury in sweetening liq in the form of more stable to form stable mercury complex, to reach suppression
Sweetening liq intermediate ion mercury processed is reduced to the technical purpose that Elemental Mercury discharges again, and specific reaction process is as follows:
[BMIM]X+ Hg2+ = [BMIMHg]Xn 3-n(n=1,2,3；X is Cl or Br).
One of preferably, the glyoxaline ion liquid is 1- butyl -3- methylimidazole villaumite or 1- butyl -3-
Methylimidazole bromide.
One of preferably, the wet desulfurizing process is the flue gas polution control treatment measures of coal-burning power plant.
The method have the benefit that:
1. the present invention adds a small amount of glyoxaline ion liquid using the sweetening liq of Limestone-gypsum Wet Flue Gas Desulfurization Process technique as matrix
As the reaction medium for inhibiting ionic mercury reduction, the two concertedness is good, effectively removes SO in realization industrial smoke2While can
Reliably, efficiently ionic mercury absorbed in sweetening liq is inhibited to be reduced into Elemental Mercury and discharge again, entire technological measure is simple
It is easy, economical and practical, it will not influence the flue gas desulfurization effect of Limestone-gypsum Wet Flue Gas Desulfurization Process technique；
2. glyoxaline ion liquid selected by the present invention is made of organic cation and inorganic/organic anion, tool
Have the characteristics that it is environmentally protective, can operation temperature is wide, thermal stability is good, stable chemical performance, vapour pressure are extremely low, in sweetening liq
When ionic mercury reduction being inhibited to discharge again, from volatilizable amount is few in sweetening liq, it can be effectively reduced in sweetening liq
Glyoxaline ion liquid because inhibit ionic mercury reduction discharge again due to caused by glyoxaline ion liquid itself volatilization environment is made
At pollution, clean and environmental protection；In addition, glyoxaline ion liquid selected by the present invention has good dissolubility to organic matter
Can, be conducive to the waste water subsequent processing of fume treatment industrial enterprise, particularly coal-burning power plant, this can enhance again from another angle
Its environmental-protecting performance.
