Description
Technical field:
The utility model relates to a kind of novel hot flue gas composite desulfate tower, belongs to the environmental protection equipment technical field.
Background technology:
China's SO2 emissions are huge, and atmospheric environment has been caused severe contamination, discharging SO in 2011
22217.9 ten thousand tons, discharge capacity ranks first in the world, and has surpassed the self-purification capacity of China's atmospheric environment, year Precipitation pH accounts for 40% of area less than 5.6 zone, causes the tremendous economic loss, has a strong impact on China's ecological environment and people ' s health.SO
2The formation of discharging and acid rain is mainly derived from fire coal, metallurgy, chemical industry.
Along with the development of Technological Economy, the going deep into of circular economy concept, ammonia process highlights its advantage, except the desulfuration efficiency height, also has the part of removing NO
XAbility.
Traditional hot flue gas desulfurization absorption equipment is that flue gas enters scrubbing tower cleaning dust after cooling tower cools, enter absorption again.Tower absorbs SO
2Three towers need be set, and process route and pipeline are long, and occupation of land is many, and equipment investment is big.
By literature search, do not see the open report identical with the utility model.
Summary of the invention:
The purpose of this utility model is, overcomes the deficiency of prior art, and it is the novel hot flue gas composite desulfate tower of one that the cooling of a kind of thermal-arrest flue gas, cleaning dust, absorption and oxidative function are provided.
Novel hot flue gas composite desulfate tower of the present utility model is by tower body 1, the washing absorber portion 10 that places tower body 1 top and exhanst gas outlet 11, place cooling concentration section, the oxidation panel of tower body 1 bottom to form; Wherein: the washing absorber portion 10 by demister 2, place the spray equipment 3 of demister 2 bottoms and absorption liquid reflux line 9 to constitute; The cooling concentration section is made of the cooling concentration section spray equipment 4, hot gas approach spray equipment 5 and the dividing plate 8 that place washing absorber portion 10 belows; Oxidation panel is made of zoneofoxidation 6 and microporous aeration device 7.
Operation principle of the present utility model is:
1, hot flue gas at first enters desulfurizing tower tower body 1 bottom, contact with ammonium sulfate under top spray, by spray washing, flush away dust in flue gas, flue gas cools off because of adiabatic evaporation in this process.Simultaneously, ammonium sulfate concentrates because of the evaporation of moisture, and concentration improves gradually, and its heat of evaporation is supplied with by fume afterheat.Reach certain technology controlling and process index, ammonium sulfate enters sulphur ammonium concentrate storage tank automatically, enters following process again and becomes solid ammonium sulfate.
Flue gas enters epimere by the riser on desulfurizing tower hypomere and the epimere space bar after washing---washing absorber portion 10.At washing absorber portion 10, flue gas passes spray equipment 3 from bottom to top, after demister 2 demists of tower body top, discharges by exhanst gas outlet 11 again.At spraying layer, the flue dust in the flue gas is washed again, simultaneously the SO in the flue gas
2Be absorbed the absorption liquid absorption that the liquid circulating pump is sent here.Absorption liquid falls into zoneofoxidation 6 subsequently by reflux line 9, be ammonium sulfate by microporous aeration device 7 with inferior salt ammonium sulfite and ammonium bisulfite solution oxide, big portion sends into absorber portion spray equipment 3 after the pressurization of absorption liquid circulating pump, continue circulated sprinkling and absorb; The absorption liquid shunting that system increases enters thickener, extracts cooling concentration section spray equipment 4 out by sulphur ammonium liquid circulating pump.Along with the carrying out of absorption process, liquid absorption element constantly changes, and absorbability is reduced.For keeping absorption efficiency, must constantly replenish new desulfurizing agent---ammoniacal liquor makes absorbent obtain regenerating.If special-purpose ammonia vessel replenishes absorbent ammoniacal liquor.The interpolation of ammoniacal liquor detects regulation and control by the pH value of absorption liquid circulation line cocycle liquid.
The utility model compared with prior art, not only simple in structure, and have higher purification and absorption efficiency, simplified traditional process route simultaneously, significantly reduce number of devices and plant area area, reduced smoke gas treatment construction investment and operating cost significantly.
Description of drawings:
Accompanying drawing is the utility model device structure schematic diagram.
The specific embodiment:
Hot fume desulfurating absorption tower of the present utility model is by tower body 1, the washing absorber portion 10 that places tower body 1 top and exhanst gas outlet 11, place cooling concentration section, the oxidation panel of tower body 1 bottom to form; Wherein: the washing absorber portion 10 by demister 2, place the spray equipment 3 of demister 2 bottoms and absorption liquid reflux line 9 to constitute; The cooling concentration section is made of the cooling concentration section spray equipment 4, hot gas approach spray equipment 5 and the dividing plate 8 that place washing absorber portion 10 belows; Oxidation panel is made of zoneofoxidation 6 and microporous aeration device 7.
The course of work of the present utility model is:
1, hot flue gas at first enters desulfurizing tower tower body 1 bottom, contact with ammonium sulfate under top spray, by spray washing, flush away dust in flue gas, flue gas cools off because of adiabatic evaporation in this process.
2, flue gas enters epimere by the riser on desulfurizing tower hypomere and the epimere space bar after washing---washing absorber portion 10.At washing absorber portion 10, flue gas passes spray equipment 3 from bottom to top, after tower body top demister demist 2, discharges by exhanst gas outlet 11 again.
3, absorb SO
2Absorption liquid enter zoneofoxidation 6, by microporous aeration device 7 inferior salting liquid is oxidized to ammonium sulfate, part enters thickener, concentrate by the hot flue gas of spray washing, reach certain technology controlling and process index, ammonium sulfate enters sulphur ammonium concentrate storage tank automatically, enters following process again and becomes solid ammonium sulfate.
The utility model uses and shows, can reach designing requirement fully.
