The device comprises a desulfurizer (1) provided with an air inlet (2) at the lower portion and an air outlet (3) at the top. The desulfurizer (1) further comprises a washing unit, a wire mesh demister (12), a spray nozzle (5), a plurality of cleaning chambers (7) and a bottom groove (8) from bottom to top, wherein a base plate (6) of each cleaning chamber (7) is provided with a plurality of holes for smoke and absorption liquid to pass through; and the washing unit comprises a water inlet (14), the spray nozzle (5), a vent cap (10), a partition (11) and a water outlet (13). According to the desulphurization device, the structure is simple, the problems of short contact time and insufficient contact of the smoke with the absorption liquid are solved, by-products generated through ammonia processing on sulfur dioxide can be recycled, the occupied space is small, and the cost for equipment investment and operation is reduced greatly.
Description
Technical field
The utility model relates to a kind of circulating absorption solution ammonia desulfuration equipment, and being specifically related to ammonia is raw material reclaims oxysulfide from flue gas desulfurizer.
Background technology
The ammonia process of desulfurization is to utilize ammonia spirit to absorb the SO in the flue gas
2Produce ammonium bisulfite and sulfurous acid ammonia, and ammonium sulfite is also to SO
2Very strong absorbability is arranged, and the two all is the main absorber in the ammonia process, and ammonium bisulfite also can produce ammonium sulfite through ammonification.At present, the spray column that wet ammonia process desulfurizing technology adopted is counted the lower main cause of efficient has two.The one, because exhaust gas volumn is very big, the diameter of required desulfurizing tower is very big, and the height of desulfurizing tower is generally lower, has channeling easily, makes flue gas flow field inhomogeneous, Gu cause gas-liquid-three-phase contact area to reduce.The 2nd, the drop that spraying layer sprayed is bigger, and the mass transfer specific area is less, and mass tranfer coefficient is also little, causes gas-liquid mass-transfer efficiency to reduce.Can increase liquid-gas ratio though strengthen the circulation of desulfurizer slurry, operating cost will significantly increase again.Particularly, when needs higher to concentration ratio, the SO that throughput is bigger
2Gas (gas that for example has rich sulfur mineral burning to produce) when absorbing, the time period that flue gas contacts with absorption liquid, absorbs insufficient.
The utility model content
To above not enough the utility model a kind of circulating absorption solution ammonia process of desulfurization tower is provided, it is short mainly to solve flue gas and absorption liquid time of contact, contacts the problem that has the escaping of ammonia in insufficient, the flue gas.
The technical scheme that the utility model adopts is: a kind of circulating absorption solution ammonia desulfuration equipment, comprise desulfurizing tower, and the desulfurizing tower bottom is provided with air inlet; Exhaust outlet is arranged on the top of tower; In tower, be followed successively by washing equipment, wire mesh demister, shower nozzle, several clean rooms and kerve from bottom to top; The base plate of clean room is provided with some holes that flue gas and absorption liquid are passed through; Kerve is provided with valve, through circulating pump the circulation fluid in the kerve is transported to the absorption liquid import; Said washing equipment comprises water inlet, shower nozzle, abat-vent and delivery port, through circulating pump the water that flows out in the delivery port is transported in the water inlet.The quantity of said clean room is 3～6 layers.
Compare with traditional wet ammonia method for flue gas desulfurizing device; The utlity model has following advantage: in the clean room, form continuously and fierce flue gas turbulent flow; Greatly optimized the flue gas flow field in the desulfurizing tower; Gas-liquid mass transfer in the reinforcing desulfuration tower between flue gas and the desulfurizer slurry, and then improve desulfuration efficiency.This device forces flue gas that turbulent flow takes place on the one hand; Dead angle on the other hand removes smoke; Make flue gas in desulfurizing tower, both realize even flow field optimization by different level; Continually strengthen the mass transfer between flue gas and the desulfurizer slurry again, effectively prevented of the influence of desulfurizer slurry spray blind area, desulfurizing tower edge, thereby made gas-liquid mass transfer efficient can improve 25～35% desulfuration efficiency.In addition, the utility model also is provided with washing equipment and silk screen foam removal equipment, has reduced the escape of sulfur dioxide and ammonia, and desulfuration efficiency increases greatly; This plant area area is little, greatly reduced investment of devices and operating cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: the 1-desulfurizing tower; The 2-air inlet; The 3-exhaust outlet; The import of 4-absorption liquid; The 5-shower nozzle; The 6-base plate; The 7-clean room; The 8-kerve; The 9-valve, 10-abat-vent, 11-division board, 12-wire mesh demister, 13-discharge outlet, 14-water inlet, 15-circulating pump.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation in further detail.
With reference to Fig. 1, a kind of circulating absorption solution ammonia desulfuration equipment comprises desulfurizing tower 1, and desulfurizing tower 1 bottom is provided with air inlet 2; Exhaust outlet 3 is arranged on the top of desulfurizing tower 1; In desulfurizing tower 1, be followed successively by washing equipment, wire mesh demister 12, shower nozzle 5, four layers of clean room 7 and kerve 8 from bottom to top; The base plate 6 of clean room 7 is provided with some holes that flue gas and absorption liquid are passed through; Kerve 8 is provided with valve 9, through circulating pump 15 circulation fluid in the kerve 9 is transported to absorption liquid import 4; Said washing equipment comprises water inlet 14, shower nozzle 5, abat-vent 10, division board 11, delivery port 13, through circulating pump 15 water that flows out in the delivery port 13 is transported in the water inlet 14.
The utility model adopts flue gas and the reverse method that contacts of absorbent, reacts fully thoroughly.Flue gas gets in the tower from air inlet 1, midway will be 7 react with absorption liquid through the clean room, cigarette at last through wire mesh demister 12 foam removals, washing equipment washing after exhaust outlet 8 rows to atmosphere, product falls into kerve.Absorption liquid also constantly injects the absorption liquid import by circulating pump, sprays through shower nozzle.Absorption liquid is with after rich sulphur gas contacts, and the concentration of reaction product continues to increase.When the concentration of absorption liquid acquires a certain degree, discharge through valve, can recycle.
Though the utility model with preferred embodiment openly as above; But they are not to be used for limiting the utility model; Anyly be familiar with this art; In spirit that does not break away from the utility model and scope, certainly when can doing various variations, so being as the criterion of should being defined with the application's claim protection domain of the protection domain of the utility model.
