Concrete chemical reaction in this step is presented herein below:
Quick lime(CaO)Dry desulfurization main chemical reactions relational expression is as follows:
CaO + SO2→ CaSO3
2CaSO3+ O2→ 2CaSO4
From above-mentioned reaction relation formula, calcium oxide and sulfur dioxide in flue gas carry out reaction and generate calcium sulfite, flue gas In oxygen again calcium sulfite oxidation is become calcium sulfate.Finally, realize the removing of sulfur dioxide.
Enter sack cleaner the first pocket 8, now filter bag through the flue gas of desulfurization along admission line(High temperature resistant corrosion resistant Erosion)To particle dust intrinsic in flue gas and desuifurized effectively filtered, be concurrently deposited at filter bag surface and have neither part nor lot in reaction Desulfurizing agent continue with sulfur dioxide react generate desuifurized.When the dedusting resistance of sack cleaner the first pocket 8 reaches During 1000 Pa, the pulse valve of sack cleaner is opened, and in gas bag, compressed gas spray into sack cleaner by injection tube, will glue It is attached to the dust on filter bag surface and desuifurized remove and be deposited among sack cleaner the first pocket 8 ash bucket finally by Ash discharge is delivered to quick lime cast feeder 3 and recycles by one unloading valve 9 and the first storehouse pump 10;

Open compressed air reservoir 15 second bleeder valve 16, make compressed air inject sack cleaner through ammonia nozzle 17 Inside two pocket 24 inlet pipeline, subsequently, open weak ammonia storage tank 13 first bleeder valve 14, ammonia mass fraction is 18.3 more than % Weak ammonia mix with compressed air under compressed air induction, and inject in pipeline by ammonia nozzle 17, last and process What the second porous plate 12 was uniformly processed uniformly mixes flowing flue gas.
Flue gas containing weak ammonia is through catalyst cast feeder 19 and low-temperature SCR catalyst MnOX/ AC uniformly mixes, low Warm SCR catalyst MnOXThe lower NH of/AC effect3By NOXIt is reduced into nitrogen gas and water.Due to MnOXOxidizing to Elemental Mercury, activated carbon AC can adsorb mercury vapour and bivalent mercury, and the simple substance Hg therefore in flue gas is catalytically oxidized to bivalent mercury and is adsorbed by activated carbon AC, And then simple substance Hg in removing flue gas.Meanwhile, it is deposited on filter bag surface unreacted completely low-temperature SCR catalyst MnOX/ AC continues Participate in reaction, and will be the NO being reduced in flue gasXIt is reduced into nitrogen gas and water, simple substance Hg is catalytically oxidized to bivalent mercury and is lived Property charcoal absorption.The method is in NH3/NOXMol ratio is 0.85 ~ 1, and NH3Leakage rate is less than 3 ml/m3When, denitration efficiency is more than 90%;Mercury removal efficiency is more than 70%;
Concrete chemical reaction in this step is presented herein below:
Low-temperature SCR selective reduction denitration main chemical reactions formula is as follows:
4NO + 4NH3+ O2→ 4N2+ 6H2O
6NO + 4NH3→ 5N2+ 6H2O
6NO2+ 8NH3→ 3N2+ 6H2O
2NO2+ 4NH3+ O2→ 3N2+ 6H2O
Elemental Mercury catalytic oxidation formula is as follows:
2Hg + O2→ 2HgO
There is above-mentioned chemical equation to understand, under catalyst action, in the flue gas of about 80~180 DEG C of temperature, spray into ammonia, By NOXIt is reduced into N2And H2O.Its primary response is aforementioned four reaction equation.Meanwhile, simple substance Hg is catalytically oxidized to bivalent mercury It is tightly held by activated carbon.Because in flue gas, dust and sulfur dioxide are processed in sack cleaner the first pocket 8, so SO2/SO3Conversion ratio low, a large amount of (NH will not be produced4)2SO4Or NH4HSO4, enter without to sack cleaner the second pocket 24 Cloth bag causes to paste bag phenomenon, and can reduce catalyst and react with sulfur, and then can improve catalyst recycling number of times.
Treated clean flue gas exports from sack cleaner and discharges, and under air-introduced machine 26 effect, is entered by chimney Among air.When the dedusting resistance of sack cleaner the second pocket 24 reaches 1000 Pa, the pulse valve of sack cleaner leaves Open, in gas bag, compressed gas spray into sack cleaner by injection tube, by a small amount of dust of sock filtration, unreacted catalyst And oxidized hydrargyrum removing, and it is deposited among sack cleaner the second pocket 24 ash bucket, by the second unloading valve 22, the second storehouse Ash discharge is delivered to low-temperature SCR catalyst cast feeder 19 and recycles by pump 23.The method can ensure that efficiency of dust collection is more than 99.98%.
