Description
Technical field
The invention belongs in field of Environment Protection, more particularly to ammonia desulfurizing process, a kind of desulfurizing tower wet dust separater.
Background technology
With social city, technicalization, hommization development, industrial or agricultural obtained vigorous growth, more and more
Desulfurizing tower is employed, and the thing followed is the increase of sulphur usage amount and showing for sulfur dioxide pollution problem.At present, ammonia process takes off
Sulphur technique is generally：The flue gas of boiler discharge enters desulphurization system after being pressurized by air-introduced machine, and cooling, Ran Hou are washed first
Counter current contacting is carried out with the desulfurization slurry that is sprayed from top upwards in desulfurizing tower, occurs mass transfer and absorbing reaction, cigarette is removed
Sulfur dioxide in gas.After flue gas after desulfurization removes the drop carried secretly in flue gas through washing, mechanical demister, through desulfurization tower top
The direct exhaust chimney in portion is directly discharged into air into chimney air flue, and flow of the flue gas in desulfurizing tower refers to accompanying drawing 1.
And with the popularity of humanized concept, and new harmonious society composition, be very important in desulfurization, with state
Requirement of the family to environmental protection is more and more tighter：It is newest《The General Office of the State Council is on printing and distributing energy development Strategic Action Plan（2014—
The year two thousand twenty）Notice》Middle to require, Air Pollutant Emission concentration limit is under the conditions of benchmark oxygen content 6%, flue dust, titanium dioxide
Sulphur, discharged nitrous oxides concentration are respectively no higher than 10,35,50 milligrams/cubic metre, are taken off using the ammonia process of tradition machinery dust collection method
Sulphur technique faces the exceeded problem of smoke dust discharge concentration in flue gas, to ensure that smoke content is up to standard in flue gas after the ammonia process of desulfurization, and one
As processing method be：Deep purifying is carried out to the flue gas after desulfurization using wet-esp, makes smoke content in flue gas
The problems such as being discharged after up to standard, but will also result in cost of investment and the operating cost increase of the ammonia process of desulfurization simultaneously, to handle 1,000,000
Nm3Exemplified by/h exhaust gas volumn, if increase wet-esp after the ammonia process of desulfurization further removes dust treatment to flue gas, it is contemplated that
Cost of investment 30,000,000 need to be increased, meanwhile, the power consumption increase 450kWh when ammonia process of desulfurization is run considerably increases the ammonia process of desulfurization
Operating cost.
After the ammonia process of desulfurization ammonium sulfate and sulfurous acid are dissolved with flue gas in the mainly drop of flue gas entrainment of flue dust source
Hydrogen ammonium aerosol etc..Because environmental administration to the detection mode of smoke content in flue gas is：Hand sample, then dries, weighs
Method measures the content of flue dust in flue gas, the ammonium sulfate and bisulfite dissolved in the drop that this detection method will certainly carry flue gas secretly
Ammonium aerosol etc. is included in the content of flue dust in flue gas.So, by reducing the ammonium sulfate dissolved in the drop that flue gas is carried secretly and Asia
Ammonium hydrogen sulfate aerosol load, can reduce the content of flue dust in flue gas after the ammonia process of desulfurization.
The content of the invention
The technical problem of solution：The application provides a kind of desulfurizing tower wet dust separater, solves existing desulfurizing tower wet type and removes
Equipment in dirt device is complicated, and smoke content is high, the technical problem such as cost height, and flue dust contains in discharge flue gas after the reduction ammonia process of desulfurization
Amount.
Technical scheme：A kind of desulfurizing tower wet dust separater, including washing spraying layer, on the washing spraying layer of desulfurizing tower
Portion sets wet dust removal section, and wet dust removal section upper and lower part sets one layer of filler respectively, and respectively upper strata filler and lower floor fills out
Material, upper strata filler upper and lower sets one layer of spraying layer respectively, respectively upper spraying layer and lower spraying layer, upper spraying layer and lower spray
Drenching layer is connected with wet dust removal pump output terminal, and upper spraying layer and lower spraying layer porch are provided with motor-driven valve, lower floor's filler bottom
Provided with wet dust removal drip tray, wet dust removal hydrops tray bottom is provided with hydrops passage, and wet dust removal drip tray passes through hydrops passage
It is connected with wet dust removal tank, wet dust removal pot bottom is provided with fluid passage, fluid passage is connected with wet dust removal pump input.
Beneficial effect：1. by setting filler respectively wet dust separater is upper and lower, wet dust removal circulation fluid can be reached
The purpose cleaned twice to flue gas during a Sprayer Circulation.Improve the effect of wet dust removal.2. wet dust removal is filled
The spray liquid upward spraying in lower spraying layer is put, liquid film is formed in upper strata filler bottom surface, flue gas needs guiding through liquid in uphill process
Film, so that the high drop of the ammonium sulphate content for displacing flue gas entrainment, meanwhile, using the water solubility of ammonium sulfate, it will be pressed from both sides in flue gas
The solid ammonium sulfate particulate of band is dissolved in wet dust removal circulation fluid.Reach the purpose of the sour ammonium dust of reduction sulfureous in flue gas.
