Description
Technical field
The utility model relates to a kind of smoke eliminator, and especially the emission abatement integration apparatus belongs to electric power, metallurgy, environmental protection and chemical technology field, especially is fit to the flue gas desulfurization technique field.
Background technology
The boiler of combustion of fossil fuels, the flue gas such as thermal power plant or steam power plant and metallurgical industry discharging contains acidic gaseous materials such as SOx, NOx, HCl and HF, SO especially wherein
3Gas makes flue gas show acid dew piont corrosion.The acid dew point of flue gas is between 100～150 ℃.In order to ensure not occurring acid dew piont corrosion in the fume emission process, the temperature during fume emission is higher 15～25 ℃ than dew point.
A large amount of fume emissions have caused the acid rain pollution.A kind of way that solves the acid rain pollution is exactly the purification of flue gas, and especially adopting alkaline matter is the flue gas desulfurization (FGD, Flue Gas Desulfurization) of raw material.Among the FGD, common alkaline matter is the natural crystal raw material, such as lime stone, i.e. and calcium carbonate, also has giobertite, the mixed ore of a kind of calcium carbonate and magnesium carbonate also has artificial synthetic alkaline matter, comprises weak base ammonia and caustic soda NaOH, for ease of discussing, respectively they are called calcium method, magnesium method, ammonia process and sodium method.The purification efficiency of FGD can reach more than the 95-99%, is extensive adopted method therefore.
Conventional FGD process mostly is the wet type operation, promptly the alkaline matter that is adopted must be mixed into a kind of alkaline aqueous solution with water, make it again to contact closely with flue gas, and guarantee purification efficiency in order to improve contacting efficiency, all adopt the aqueous solution of extremely low concentration, in the calcium method, the per kilogram flue gas needs the aqueous solution of 10-30 kilogram.So under the operating condition, flue gas is through contact arrangement, or after being called purifier and desulphurization plant, temperature obviously can be lower than acid dew point, more seriously, and the former SO that is present in the flue gas
3Can become sulfuric acid mist, make flue gas after being purified demonstrate strong acid corrosion.
Ways of addressing this issue has two kinds, the one, to the original former flue gas of direct discharging (without purification, and temperature is more than acid dew point, such as greater than 120 ℃) chimney (being called former chimney) carry out anti-corrosion treatment, make that again purifying flue gas gets back to former smoke stack emission, but it invests high, and for old equipment, such as old unit, boiler or sintering machine, can exist long-play to interrupt, influence is produced.In order to remedy the defective of this method, people have proposed another kind of method, are exactly that a chimney directly is set on purifier, be called in line chimney, or the top smoke evacuation chimney, make purifier have the incorporate function of emission abatement, this method investment is low, and can not influence production.
But, in the practice, it is found that this emission abatement integration apparatus that has in line chimney moves comparatively difficulty, be difficult to the effect that reaches default, comprise that purifying is that desulfuration efficiency is low, the consumption of raw materials height, but also can bring white plume contamination, even can produce misty rain, thereby seriously restricted the application of this equipment.

Outside the in line chimney stack; preferably be enclosed with smoke elimination rain member from top to bottom; and outside this member, also be enclosed with the protection shell; the thickness of described smoke elimination rain member is between 10～200mm; optimally at 80～150mm; be preferably between 50～120mm; described smoke elimination rain member adopts thermal conductivity factor to make less than the material of 0.5W/C.m; so that effectively reduce the flue gas condensing water yield of inner wall of stack; thereby reduce flue gas and carry and then eliminate misty rain secretly; described protection shell adopts aluminum material to make, and the thickness of this protective layer is guaranteed lighter quality and good barrier propterty at 0.3～1.5mm.
The disclosed smoke eliminator of the utility model is operated in the following manner:
Contain SO
2, SO
3, NO
2HCl/HF, the flue gas of pollutants such as flue dust, enter purifying column (being also referred to as desulfurizing tower) from advancing the cigarette interface, upwards flow, with washing absorption liquid (containing alkaline matter in the absorption liquid) counter current contacting of atomization of liquid element aerosol dispersion, the chemical reaction in mass transfer, heat transfer and the liquid phase of generation solution-air two-phase is deviate from pollutant.SO in the flue gas
2Become sulphite, SO
3Become sulfuric acid mist, also have part to become sulfate, HCl becomes chloride.The eliminating efficiency of these acid contaminants can reach 95%.The eliminating efficiency of the flyash in the flue gas (dirt) is greater than 60%-90%.
The washing absorption liquid is the pulpous state aqueous solution that contains alkaline desulfurizing agent, sulfate and crystalline solid thereof, and generally all is saturated near sulfate, preferably saturated the or oversaturated pulpous state aqueous mixtures by sulfate.
Big for unit or boiler capacity, perhaps SO in the flue gas
2The situation that concentration is high, if adopt extremely low calcium raw material (calcium method) or the magnesium raw material (magnesium method) of solubility, the cleaning solution flow will be very huge, flue gas must be through too much group of absorption liquid disperser, further upwards flow again and contact with the gas-liquid separation element, removing the flue gas droplets entrained, mostly is the muddy drop that contains solid.To removing the water flushing that the liquid member is also regular or the gap employing is cleaner, guarantee that the gas passage of gas-liquid separation element is unobstructed simultaneously.
After leaving the gas-liquid separation element, flue gas continues upwards to flow, and passes the smoke interface that is positioned at the purifying column top, enters the in line chimney that is positioned on the purifying column, directly enters atmosphere.Because outside the in line chimney stack, all being surrounded by smoke elimination rain member from top to bottom especially guaranteed the less condensed water that occurs of inner wall of stack, or condensed water seldom occurred, like this, flue gas is carried condensing drip secretly and misty rain occurred with regard to not returning by chimney.
On the other hand, the washing absorption liquid flows downward, contact with flue gas adverse current, be back in the tower body below the cigarette interface into, air oxidation by the dispersion of air bubbling element blasts makes sulphite become sulfate, becomes calcium sulfate and forms gypsum (calcium sulphate crystal that promptly has two crystallizations water) such as calcium sulfite, or ammonium sulfite is oxidized to ammonium sulfate, and then crystallization is corresponding crystal.Therefore, this section is also referred to as oxidation pond, or oxidizing and crystallizing pond, especially absorption liquid circulating slot.Fresh desulfurizing agent is such as the lime stone powder slurries of granularity more than the 250-325 order, and magnesia/magnesium carbonate slurries, or liquefied ammonia/vaporous ammonia/ammoniacal liquor directly are added in the cigarette interface circulating slot.Absorption liquid is by being arranged on outside the purification tower, the circulation fluid conveyer that is connected with tower body by circulating line is repeated to be transported to and is positioned at the into atomization of liquid element of the tower body of cigarette interface top, so as to make purifying column realize gas cleaning continuously and stable operation.
Simultaneously also must constantly get rid of absorption liquid, enter follow-up sulfate solid and separate and process equipment, to obtain desulfurization product, solid sulfate salt from circulating slot.
By above-mentioned disclosed technical scheme as seen, gas cleaning of the present utility model discharging integration apparatus has comprised four parts: be respectively air bubbling element, absorption liquid atomizing element, gas-liquid separation element from bottom to up and have the in line chimney of smoke elimination rain effect, make purifier efficient height, energy consumption is low, invest lowly, can also overcome simultaneously the shortcoming of existing equipment.
