Description
Technical field
This novel sintering flue gas desulfurization technical field that belongs to specifically is a kind of desulfurizing tower that adopts seawater to sintering flue gas desulfurization.
Background technology
Current, though steel and iron industry has become the mainstay that promotes the national economy stable and rapid development, also be one of industry of highly energy-consuming, high pollution simultaneously.Show that according to relevant data iron and steel enterprise's energy consumption accounts for 15% of national total energy consumption, SO2 emissions account for 6.6% of the whole nation.Although steel industry is the rich and influential family of power consumption and blowdown, also have the potentiality of energy-saving and emission-reduction simultaneously.
A large amount of sulfur dioxide are discharged in the atmosphere can form acid rain, destroys earth ecology, and environmental protection is brought totally unfavorable influence.For near the iron and steel enterprise on seashore, adopt the seawater method to carry out the selection that sintering flue gas desulfurization is a kind of economy, efficient, environmental protection.But the sinter fume seawater desulfurizing process must solve bioxin and the heavy metal ion secondary pollution problem to the ocean.
New by looking into, retrieve some relevant patents.As " desulphurizing tower for desulphurizing with seawater soda-residue emulsion " (grant number CN101444698A) invention, the technology of this patent is compared with simple sea water desulfuration needs the white clay additive, but the white clay that adds causes secondary pollution to the ocean easily." spray fume desulfurizing tower " (grant number CN201023026Y) invention is similar with other additive-free sea water desulfuration tower, can absorb the SO in the sinter fume
2, but can't remove sinter fume Zhong bioxin and heavy metal ion.
In sum, existing sea water desulfuration tower can't satisfy desulfurization, take off bioxin and heavy metal ion needs in desulfurization.
The utility model content
This is novel to provide a kind of sinter fume sea water desulfuration tower, can make when handling sinter fume, can absorb heavy metal ion simultaneously with bioxin reduces environmental pollution, makes the sinter fume qualified discharge.
This novel purpose is achieved by the following technical solution: comprise tower body, advance mouth, dedusting and storage ash system, the gas outlet, demister, spray column atomizer, liquid storage cylinder, liquid outlet is formed, it is characterized in that tower body is made of king-tower and secondary tower, before the king-tower spray atomizer, establish the secondary tower of a charcoal absorption, the lower end of king-tower and secondary tower is connected, to constitute U type flue, into mouth is arranged at secondary tower top, and dedusting and storage ash system are arranged at the bottom, the gas outlet is arranged at king-tower top, the king-tower inner chamber is provided with demister, the spray column atomizer, and the king-tower bottom is liquid storage cylinder and liquid outlet.
Concrete structure of the present utility model has installs 2～5 layers of netted active carbon Turbogrid plates in the charcoal absorption secondary tower, sinter fume is through after the Turbogrid plates, heavy metal ion more than 98% is Yu bioxin will be adsorbed on the active carbon Turbogrid plates, and Turbogrid plates can additionally not increase the blower fan resistance.
The utility model is primarily aimed in the sinter fume De bioxin and heavy metal ion is carried out preliminary treatment, purified by Absorption by Sea Water behind the flue gas process sea water desulfuration tower after the processing, last qualified discharge, only use seawater as desulfurizing agent in the sweetening process, reduce operating cost, simultaneously the ocean is not had secondary pollution.
Description of drawings
Fig. 1 is the utility model sinter fume sea water desulfuration tower structure schematic diagram;
Among the figure, 1 advances mouth, 2 active carbon Turbogrid plates, 3 dedustings and storage ash system, 4 gas outlets, 5 demisters, 6 spray column atomizers, 7 liquid storage cylinders, 8 liquid outlets
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
As shown in the figure, the utility model comprises tower body, advances mouth 1, dedusting and storage ash system 3, gas outlet 4, demister 5, spray column atomizer 6, liquid storage cylinder 7, liquid outlet 8 is formed, it is characterized in that tower body is made of king-tower and secondary tower, before king-tower spray atomizer 6, establish a charcoal absorption secondary tower, the lower end of king-tower and secondary tower is connected, to constitute U type flue.Into mouth 1 is arranged at secondary tower top, and there are the active carbon Turbogrid plates 2 in three layers of different aperture secondary tower inside, and wherein three layers of Turbogrid plates aperture size do not wait, and are respectively 2mm; 1mm; 0.5mm Turbogrid plates thickness is 30mm, and can regularly replace, dedusting and storage ash system 3 are arranged at the secondary tower bottom.Gas outlet 5 is arranged at king-tower top, and the inner chamber middle part is evenly equipped with shower nozzle by the spray column atomizer of being made up of annular spray pipe 6 on the spray column atomizer.Demister 5 is arranged at spray column atomizer 6 tops; The king-tower bottom is liquid storage cylinder 7 and liquid outlet 8.
Specific embodiment of the present utility model is such, sinter fume through the electrostatic precipitator dedusting enters secondary tower from air inlet 1, through the adsorption filtration of active carbon Turbogrid plates 2, can and heavy metal ion adsorbedly get off 98% above bioxin, the active carbon Turbogrid plates can regularly replace.The dedusting of secondary tower bottom and storage ash system 3 can make dust content reach 20mg/m small amount of dust in the sinter fume and the further purified treatment of active carbon dust
3Below, micro-dust can not pollute the ocean.Seawater absorbs SO by 6 ejections of spray column atomizer
2In liquid storage cylinder 7, store at last later on and discharge by liquid outlet 8.Flue gas after being purified is discharged by gas outlet 4 through demister 5 backs.
