Description
Technical field
The utility model belongs to exhuast gas desulfurization field, is specifically related to a kind ofly take ionic liquid as desulfurizing agent, and the reverse shearing of take is respectively rotary packed bed and rotary packed bed is absorption reactor thermally and desorb reactor, and continuity method removes the device of SO 2 in waste gas.
Background technology
Along with the fast development of China's economy, industrial waste gas is day by day serious on the impact of environment, wherein SO
2one of topmost industrial waste gas, 2008-2009 SO
2discharge capacity has accounted for the more than 60% of industrial gas emission total amount, controls SO
2discharge becomes the key that industrial waste gas reduces discharging.And SO in industrial waste gas
2discharge mainly concentrate on again electric power, heating power, metal smelt, nonmetallic ore Tetramune, the industries such as chemical, account for respectively SO
255%, 14%, 9.5%, 5.8% of total emission volumn.Visible, flue gas desulfurization is to reduce discharging SO
2main path.Within 2012, carried out new fossil-fuel power plant atmospheric pollutant emission standard, SO in flue gas
2exit concentration is from (400～1200) mg/m before
3be reduced to (50～200) mg/m
3, this makes existingly to take Wet Limestone/lime method and be that main flue gas desulfurization technique is difficult to qualified discharge or can not economical operation.On the other hand, the contradiction that China's sulphur resource requirement is constantly risen between scarcity relative to sulphur resource, within 2012, imported sulphur is 1,120 ten thousand tons, increases by 17.6% upper one year.Therefore, exploitation desulfuration efficiency is high, cost is low, recyclable SO
2flue gas desulfurization technique extremely urgent.
Existing wet desulfurizing process is mainly usingd the tower equipment such as packed tower, spray column, bubble tower as absorption reactor thermally, thereby, the advantage such as though the maturation of possessing skills, desulfuration efficiency high (can reach more than 90%), disposal ability are large, but ubiquity system complex, equipment volume is huge, floor space is wide, energy consumption is high, investment and operating cost high, the volatility of absorption liquid causes the unnecessary loss of absorption liquid, in running, need constantly to supplement fresh absorption liquid, water consumption is large, the waste water producing needs further to process, or produces CaSO
4the like waste, easily produces the shortcomings such as secondary pollution.Secondly, desulfurizing byproduct etc. cannot effectively utilize, even if there is certain value, also mostly need to process and could utilize through processing, and its slack market, desulfurizing byproduct is thrown aside mostly, causes the serious sulphur wasting of resources.Therefore seek a kind of not volatile, absorptive capacity large, the desulfurizer of the desirable desulfurizing agent of reusable edible and high efficiency, low energy consumption is following research emphasis and the focus.
Ionic liquid by organic cation and organic or inorganic anion, formed at room temperature or approach the salt being in a liquid state under room temperature condition, having low melting point, low-steam pressure, good thermodynamic stability and unique character such as chemical stability and adjustability of structure, is a kind of novel environmentally friendly solvent.Not only absorptive capacity is large using ionic liquid as desulfurizing agent, to remove sulfur dioxide, and because it is not volatile, there is not the loss of absorption liquid, can not produce environmentally harmful material yet, after desorb, can also recycle, absorption efficiency is still very high, and technique greenization is expected to solve in existing sulfur method byproduct for treatment difficulty, easily produces secondary pollution problems.High concentration sulfur dioxide by method solution sucking-offs such as heating can be used as liquid SO
2, sulfuric acid, sulphur and other sulfuration chemical products good raw material.Both avoid secondary pollution, reclaimed again sulphur resource.At present, ionic liquid method exhuast gas desulfurization (Chinese invention patent CN1698928A, CN1709553A, CN102126968A, CN101745290A, CN101601961A, CN101671259) technique is still in the laboratory research stage, absorption reactor thermally be take absorption bottle or absorption tube as main, by bubbling heating water bath, control and absorb temperature, TMG lactate (Angew.Chem.Int.Ed.2004,43,2415-2417), alcoholamine carboxylate (Chinese patent application 200510069406.6), [bmim] [BF
4], [TMG] [BF
4], [TMG] [BTA], [TMGB
2] [BTA] (Chem.Commun., 4027-4029,2006), ethanolamine lactate, quaternary ammonium salt plasma liquid all show good suction-operated to sulfur dioxide.Desulfuration efficiency is up to more than 90%, and equilibration time is short, but mass transport process do not strengthened, and has limited the further raising of desulfuration efficiency, and has had very large gap from the industrial applications of this desulfur technology.
High-gravity technology is a kind of process intensification new technology realizing by rotary packed bed (RPB), the centrifugal force that utilizes rotation filler to produce is simulated Elevated Gravity, liquid flow velocity is accelerated, the thickness attenuation of liquid film, high viscosity liquid particularly, alternate area and Surface Renewal speed are increased significantly, overall mass transfer coefficient improves 1～3 order of magnitude, but this is mainly because of the mass tranfer coefficient of liquid phase and the raising of phase contact area, and it is not obvious for the strengthening effect of gas phase and the raising of mass tranfer coefficient, and also there is the unequal defect of liquid distribution in existing rotary packed bed structure.And ionic liquid absorbs SO
2the process that belongs to air film and liquid film co-controlling.Thereby exploitation can be strengthened the rotary packed bed significant of gas phase and mass transfer in liquid phase process simultaneously.
In addition, rotary packed bed gas-liquid contact mode have adverse current, and stream and cross-flow minute, wherein and stream can by means of centrifugal force, produce the effect of self-priming, greatly reduce gas phase drag loss, save gas conveying energy consumption.
Based on above-mentioned analysis, the purpose of this utility model is to solve a difficult problem for existing rotary packed bed existence, and the reverse shearing of the applicable cocurrent cooling operation of exploitation is rotary packed bed as SO
2absorption equipment, ionic liquid is renewable desulfurizing method of exhaust gas and the device of circulation absorbent, the occasion such as the treating capacity that can be applicable to industrial waste gas is large, degree of purification is high.
