Description
Technical field
The utility model relates to the circulating slurry sprinkling device that uses at the limestone-gypsum wet method fume desulfurizing system.More particularly it is a kind of circulating slurry sprinkling device for desulfurization of flue gas.
Background technology
Most power plant of China and industrial boiler adopt coal, wet goods fossil fuel usually, because the fossil fuel source is unstable, quality is unstable, sulfur content is higher, can produce harmful substances such as a large amount of sulfur dioxide in combustion process.In order to remove the sulfur dioxide in the boiler smoke, large-scale coal fired power plant is extensive use of the limestone-gypsum wet desulfurization system and carries out flue gas desulfurization.The absorption tower is one of most important device in this desulphurization system.One of most important equipment is exactly a spray equipment in the absorption tower.The tradition spray equipment generally has two kinds, and a kind of is the alloy shower, and a kind of is the fiberglass shower.Use the steel alloy shower, involve great expense, and because the shower irrational distribution, the shower internal pressure is unbalanced, cause the grout distribution inequality that sprays out, slurries easily precipitate, utilization rate is not high.Some sulfur-containing smoke gas can not fully be sprayed, and it is unclean to cause sulphur content to remove, and desulfuration efficiency remains further to be improved.For reaching clean cigarette purpose, must increase sprinkling equipment or increase spray time, the power consumption of recycle slurry liquid pump is significantly improved; Use the fiberglass shower, cost is cheaper, it is also more reasonable to spray, but because glass-reinforced plastic material insufficient rigidity, need to establish beam separately in tower and support, can cause the flow field inhomogeneous because beam is set on the one hand, local sulfur-containing smoke gas can not fully be sprayed, it is unclean to cause sulphur content to remove, and desulfuration efficiency remains further to be improved.For reaching clean cigarette purpose, must increase sprinkling equipment or increase spray time, the power consumption of recycle slurry liquid pump is significantly improved, because beam is set runner is formed extra obstacle on the one hand, cause whole flue gas system resistance to rise, must increase the pressure head of booster fan, make the power consumption of booster fan significantly promote.
Summary of the invention
The purpose of this utility model provides the circulating slurry sprinkling device that a kind of fume desulfurating absorption tower uses, and solve flue gas and loop slurry undercompounding, desulfuration efficiency and remain further raising, and problem such as the absorption tower flow field is inhomogeneous, and flue gas resistance is bigger.
The purpose of this utility model reaches by following measure: circulating slurry sprinkling device for desulfurization of flue gas, it is stratified and set in the absorption tower, it is characterized in that every layer of spray equipment is mainly by at least one spray person in charge, be responsible for a plurality of spray arms that two ends are told from spray, form from a plurality of nozzles that each spray arm both sides is told, described spray is responsible for and is fixed on the absorption tower.
In technique scheme, described spray is responsible for and is internal layer and the outer carbon steel pipe that is lined with the butyl rubber layer.
In technique scheme, described spray arm is to be internal layer and the outer glass reinforced plastic pipe that is lined with the wear-and corrosion-resistant layer.
In technique scheme, described spray arm is responsible for spray and is connected by flange.
In technique scheme, twine also bonding between described nozzle and the spray arm by fiberglass cloth.
In technique scheme, the end of described spray arm is arranged on the saddle bracket on the inwall of absorption tower.
In technique scheme, described nozzle is unidirectional downward spray structure or two-way spray structure, and the nozzle of unidirectional downward spray structure is positioned at the top layer spraying layer, and the nozzle of two-way spray structure is positioned at the below of top layer spraying layer.
1., energy consumption greatly reduces compare with the spray equipment of routine, the utility model has following beneficial effect:.Owing to do not need to be provided with in addition brace summer, make the absorption tower flow field more even on the one hand, reduced the dead angle of spray, make spray efficient improve greatly, greatly reduce the power consumption of recycle slurry liquid pump, compare with the spraying layer that is provided with brace summer, reaching under the condition of identical desulfuration efficiency, the energy consumption of recycle slurry liquid pump reduces by 3%; Make that on the other hand the absorption tower inner flow passage is more unobstructed, compare with the spraying layer that is provided with brace summer that it is about 6% that the absorption tower has been reduced the resistance of flue gas, the energy consumption of booster fan has reduced about 2%.2., construction is convenient.Spraying layer supporting construction of the present utility model is reasonable, and spray is responsible for and is directly fixed on the absorption tower, because rigidity own is enough big, so do not need to be provided with brace summer, makes that whole spraying layer is simple for structure.In the spraying layer spray be responsible for the spray arm between for flange is connected, this interface is arranged so that easy construction, quick, working face is little, is convenient to processing and manufacturing and scene installation.3., with low cost.Be lined with the carbon steel pipe material of butyl rubber inside and outside spray is responsible for and is adopted in the spraying layer of the present utility model, inside and outside adopting, the spray arm is lined with the glass reinforced plastic pipe material of wear-and corrosion-resistant layer, the slurries spray adopts sintered sic to make with nozzle, nozzle adopts the winding bonding way to be connected with shower, whole cost reduces greatly, investment is also reduced significantly, and its spraying layer cost has only the less than 20% of alloy material, hangs down about 10% than the spraying layer cost that fiberglass is responsible for.
