Description
Technical field
The utility model belongs to field of Environment Protection, relates to a kind of spray column in particular.
Background technology
Sulfur dioxide affects larger gaseous contaminant in atmosphere pollution, has high risks to human body, environment and the ecosystem.Along with the increasingly stringent of environmental requirement, the problem of S02 discharge more and more receives publicity.Sulfur dioxide mainly stems from the combustion process of the fossil fuel such as coal, oil, and the roasting of ore, the fume emission of smelting process.Wherein various burning boiler particularly power plant boiler smoke evacuation there is the features such as concentration is low, exhaust gas volumn is large, floating dust is many and be difficult to administer.Discharge sulfur dioxide in flue gas purification techniques normally carries out desulfurization by spray column.
Current spray column generally includes tubular tower body, slurry pool is provided with at the bottom of tower body, the corresponding slurry pool top of tower body is provided with air inlet, tower body top is provided with gas outlet, shower is provided with in the middle of the corresponding air inlet of tower body and gas outlet, shower is provided with shower nozzle, outside tower body, is also provided with the conduit connecting slurry pool and shower.
Pollute flue gas in use and enter tower body inside from air inlet, slurry pool is built with alkaline solution, alkaline solution is back to shower through conduit, is sprayed by shower nozzle, and the sulfur dioxide generation neutralization reaction in the alkaline solution of ejection and the pollution flue gas of rising purifies to reach and pollutes the object of flue gas.
But in actual use, because the exhaust gas volumn produced in boiler combustion process is larger, flue gas flow rate is fast, flue gas is when air inlet enters tower body inside, to directly impact the opposite side of the corresponding air inlet of tower body, skewness in tower body, under part shower nozzle, flue gas concentration is large, cause alkaline solution can not to react completely with the sulfur dioxide in flue gas, as increased the concentration of alkaline solution, not only increase cost consumption, and it is larger to tower body damage, reduce service life, and the alkaline solution of part shower nozzle ejection is very unnecessaryly directly fallen in slurry pool, again be circulated in shower by power set through conduit, cause the waste of power resource, simultaneously because exhaust gas volumn is larger, when entering from an air inlet, flue gas is deposited in together, causes alkaline solution all cannot penetrate flue gas equally and is neutralized by the sulfur dioxide in flue gas, below all cause sulfur dioxide to eliminate unclean, the smoke pollution of discharging from gas outlet is still larger.
Utility model content
For the deficiencies in the prior art, the utility model provides one makes flue gas be evenly distributed in tower body, the spray column that the sulfur dioxide effect simultaneously in removing flue gas is better.
For achieving the above object, the utility model provides following technical scheme: a kind of spray column, comprise tubular tower body, slurry pool is provided with bottom tower body, tower body top is provided with gas outlet, is provided with some spraying layers in tower body, forms some spray chambeies between some spraying layers, corresponding some spray chambeies are provided with air inlet to tower body, and some spraying layers are provided with some showers and some atomizers.
By adopting technique scheme, in use, some air inlets are evenly spread to from boiler pollution flue gas out, tower body inside is entered from some air inlets, then the exhaust gas volumn that enters of each air inlet is by much smaller than the exhaust gas volumn only having an air inlet, the flue gas that then dispersion enters in tower body will easilier spread out in spray chamber, the admission velocity of flue gas will reduce simultaneously, and relative concentration reduces more when an air inlet, now alkaline solution sprays from atomizer through shower, be more prone to and the sulfur dioxide generation neutralization reaction sprayed in chamber in flue gas, make desulfurized effect more thorough, the alkaline solution of ejection can not be wasted simultaneously, flue gas after purification is discharged from gas outlet.
The utility model is set to further: some showers are all in circular, and some showers of same layer are that concentric circles is arranged successively, and atomizer is evenly distributed on shower.
By adopting technique scheme, shower is circular distribution, and then atomizer is evenly distributed on shower, and the alkaline solution of the ejection made is evenly distributed in some spray chambeies more, further flue gas is carried out complete purification.
The utility model is set to further: be provided with tubular deflector in some spray chambeies, is provided with the interlayer for flue gas dispersion, deflector offers some through holes, be connected with fixed bar between deflector and tower body between deflector and tower body.
By adopting technique scheme, flue gas is when air inlet enters spray chamber, first deflector is touched, flue gas be subject to the stop of deflector and water conservancy diversion by be distributed to deflector and tower body interlayer among, then enter spray chamber again by through hole, directly can not impact on the another side of the corresponding air inlet of tower body because of speed when flue gas is entered in spray chamber, and then make flue gas can not gather a place, flue gas enters spray chamber uniformly by uniform in each through hole of deflector, and then ensure that the gas cleaning effect of each position in spray chamber is identical and best, deflector is fixed on tower body inside by fixed bar.
The utility model is set to further: be connected with conduit between slurry pool and shower.
By adopting technique scheme, the alkaline solution sprayed by atomizer has surplus always when real work, so that more thorough by gas cleaning, alkaline solution will fall in slurry pool after atomizer ejection, by conduit, the alkaline solution in slurry pool is led back in shower again, make alkaline solution complete reaction, avoid waste.
Compared with prior art, the utility model spray column makes flue gas be evenly distributed in tower body, and the sulfur dioxide effect simultaneously removed in flue gas is better, and desulfurization is more thorough.
