In the device, a chimney of the curing barn is connected with a centrifugal induced draft fan, an outlet of the fan is connected to one end of a closed box, Ca(OH)2 absorption liquid is filled in the box, the other end of the box is provided with a device chimney, a stirrer is arranged between the centrifugal induced draft fan and the device chimney, a blade of the stirrer is arranged in the absorption liquid, and the rotating speed of the stirrer is high enough so that fog droplets with a diameter being less than 3mm are produced in a space above the absorption liquid. The dust removal, desulfurization and denitration device disclosed by the utility model is simple in structure, easy to operate, and easy to popularize in the rural areas, can minimize the consumption of Ca (OH) 2, and can absorb and purify pollutants very well, so that the treatment cost and the purifying effect are matched perfectly.
Description
Technical field
The invention belongs to flue-gas purification equipment, be specifically related to a kind of pollution fume treatment auxiliary that reduces dedusting, desulfurization and the denitration of tobacco curing barn flue gas.
Background technology
At present, dedusting, desulfurization and denitration device are mainly used on thermal power plant, cement plant and coal fired boiler.These equipment generally have take up an area large, cost is high, is difficult to apply on the tobacco curing barn equipment of rural area, therefore has the problems such as difficult of promoting.
The tobacco leaf condensed type hothouse baking in rural area in recent years, particularly toasts the appearance at workshop, makes the intensive baking room of single seat towards clustering future development, causes curing barn cluster overhead pollutant to increase, dust, CO
2, SO
2increase with the noxious gas emission content such as nitre state compound.
Dedusting, desulfurization and denitration device are installed at intensive baking room exhaust opening place, barn flue gas is purified, reduce the discharge of barn exhaust pollutant, reach emission reduction effect and become urgent problem to be solved, therefore need research and development special dedusting, desulfurization and denitration device for tobacco leaf condensed type barn.
Summary of the invention
The object of the present invention is to provide a kind of dedusting, desulfurization and denitration device that reduces barn flue gas, it is simple in structure, and processing ease is easy to promote in rural area.
For achieving the above object, the key problem in technology that the present invention adopts is: barn chimney connects centrifugal type draught fan, and fan outlet accesses airtight casing one end, packs Ca (OH) in casing into
2absorption liquid, on casing, the other end is equipped with equipment chimney, between centrifugal type draught fan and equipment chimney, agitator is housed, and the blade of agitator inserts in absorption liquid, and the rotating speed of agitator reaches and makes absorption liquid superjacent air space produce the vaporific drop that is less than 3mm.
Described Ca (OH)
2the be weight percentage aqueous solution of concentration 7～9% of absorption liquid, pH value is constant to be remained between 5～6, and in water tank, absorption liquid volume accounts for 1/2～2/3; Centrifugal type draught fan is other to be connected on barn chimney, on the barn chimney of other interface top, is provided with a coffer.
For 0.9～1.5M
3cabinet configuration centrifugal type draught fan power be 0.65kw, rotating speed 1450rpm; Configuration agitator paddle rotating speed is 480rpm, and impeller diameter 620mm, is provided with blow-off pipe in the bottom of casing.
The operation principle of device of the present invention is, flue gas is under the effect of air-introduced machine, enter into the casing that limewash is housed, by the blade of mixer, stir and form water smoke, water smoke and flue gas and carry out oxidation reaction, form calcium carbonate and calcium sulfate precipitation thing, the dust in flue gas just precipitates after limewash simultaneously, and flue gas after filtering is just discharged from main stovepipe, sediment will regularly be discharged from blow-off pipe, reach the objects such as dedusting, desulfurization and denitration.
The invention has the beneficial effects as follows: this purifying processing device is simple in structure, cost is lower, processing ease, and suitable tobacco grower uses.According to the pollutant mainly containing in flue gas, be soot dust granule (generally between 10 μ m～100 μ m), gas SO
2, oxynitrides and nitre state compound thereof, therefore selected Ca cheap and easy to get (OH)
2as absorption liquid, and take rational Ca (OH)
2absorption liquid concentration and pH value, can reduce Ca (OH) to greatest extent
2consumption, guarantees again the better absorption cleaning to pollutant simultaneously, makes processing cost and clean-up effect reach optimum Match.

The specific embodiment
For making object of the present invention, embodiment and a little clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Barn chimney 1 connects centrifugal type draught fan 3, and fan outlet accesses airtight casing 6 one end, packs Ca (OH) in casing 6 into
2absorption liquid 7, Ca (OH)
2the be weight percentage aqueous solution of concentration 7～9% of absorption liquid, pH value is constant to be remained between 5～6, and in water tank, absorption liquid volume accounts for 1/2～2/3.On casing 6, the other end is equipped with equipment chimney 5, between centrifugal type draught fan 3 and equipment chimney 5, agitator 4 is housed, and the blade of agitator 4 inserts in absorption liquid 7, and the rotating speed of agitator 4 reaches and makes absorption liquid 7 superjacent air spaces produce the vaporific drop that is less than 3mm.Centrifugal type draught fan 3 is other to be connected on barn chimney 1, on the barn chimney 1 of other interface top, is provided with a coffer 2, and the pollutant flue gas of barn chimney 1 is guided in casing.For the conventional barn in rural area, suitable outfit 0.9～1.5M
3casing 6, centrifugal type draught fan 3 power that this casing 6 is equipped with are 0.65kw, rotating speed 1450rpm; Agitator 4 wheel speeds of configuration are 480rpm, impeller diameter 620mm.In Tobacco Leaf Curing, stir limewash every day 1～2 time; Often a roasting stove cigarette, opens the blow-off pipe 8 that casing 6 bottoms arrange, and removes casing 6 bottom precipitation things.
The result is as shown in table 1.
Table 1 flue gas pollutant is measured
Adopt LANDC-390H high accuracy flue gas analyzer to measure flue gas pollutant, dust, SO
2, oxynitrides content all obviously reduces, and reaches emission reduction effect.
