Description
Technical field
The utility model relates to technical field of desulfurization, particularly the air inlet distribution technique of major diameter sulfur dioxide absorbing tower.
Background technology
SO
2be in atmosphere pollution, affect larger pollutant, have high risks to human body, environment and the ecosystem.It 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.At present, conventional flue gas desulfurization technique mainly contains wet method, dry method and semidry method etc.Wherein wet fuel gas desulfurizing technology is owing to having that operational reliability is good, desulfuration efficiency is high and the advantage such as byproduct recovery, has become the flue gas desulfurization technique of main flow.In wet fuel gas desulfurizing technology, desulfurizing tower is the core component of whole technique, and conventional desulfurizing tower mainly contains spray column, liquid column tower, bubble tower and loop tower etc.In such towers, spray column has the advantages such as structure is simple, resistance is little, obtains a wide range of applications.
At present, the airflow uniform distribution mode that most spray column adopts is: inlet pipeline is downward-sloping air inlet at a certain angle, air-flow self dilatation, diffusion and effect of inertia is relied on to carry out air flow method, but such airflow uniform distribution effect is limited, in tower, air flow method is still uneven, and local, Ta Bi side, entrance opposite wind speed is excessive, and the serum density of this part region spray is little, mostly be sticking wall flow, so cause SO in fraction
2removal efficiency is low, and meanwhile, local wind speed is excessive playing a role of also can making that demister can not be good, causes the phenomenon that the stagnant liquid of exhanst gas outlet is serious, both polluted surrounding environment and wasted absorbent.
Utility model content
The utility model object is to provide a kind of absorption tower with large diameter double feed inlet multi-drop gas distributor, to be applicable to the Gas distribution in large diameter sulfur dioxide absorbing tower.
The utility model arranges two air inlet pipe in the outside of the tower body of cylindrical absorbent tower, each air inlet pipe connects at least two pieces points of bronchial one end respectively, the each point of bronchial other end is connected with tower body respectively, and each point of bronchus reduces gradually from the link of the corresponding air inlet pipe caliber to the link with tower body; Each point of bronchial axis Zi to the link of tower body to the link with corresponding air inlet pipe in being in tilted layout, and each point of bronchus to one end that tower body connects lower than the one end be connected with corresponding air inlet pipe.
The utility model only needs the air inlet pipe arranging double feed inlet multiple-limb to change gas flow, thus reaches reduction pressure drop, equally distributed object.Offer because a point bronchus is tilted to down, when gas enters after in tower, substantially can not there is the collision of air-flow, and the time of staying of gas in tower can be increased, effectively increase the time of contact of flue gas and circulating absorption solution, thus improve the reaction efficiency of flue gas and circulating absorption solution.
Branched pipe diameter reduces gradually, Venturi nozzle is formed with air inlet pipe and absorption tower, increase the flow velocity of gas, gas turbulence degree is increased, decreases air film resistance, increase mass transfer rate, simultaneously, effectively can also increase gas liquid interfacial area, extend gas-liquid contact time, improve the reaction efficiency of flue gas and circulating absorption solution.
The utility model adopts the air inlet pipe gas distributor of double feed inlet multiple-limb, can increase efficiently flue gas and circulating absorption solution to flow area and the time of staying, thus improve the reaction efficiency of flue gas and circulating absorption solution, raising SO
2removal efficiency, reduce the pollution to environment.
In addition, two air inlet pipe axis described in the utility model are in same level, and tangent with a concentric circles of tower body.Bidirection air intake can make gas be evenly distributed in tower.
The joining of each point of bronchial axis and tower body is arranged on the same disc perpendicular to tower body axis, and the joining of point bronchial axis and tower body is arranged symmetrically with the center of circle of this disc.On described disc, the angle (λ, μ) of the line between the joining being connected to each point of adjacent bronchial axis in same air inlet pipe and tower body to the described center of circle is respectively 25 ° ~ 45 °.Such layout is not only convenient enters a point bronchus by air inlet pipe, and ensures the reasonable Arrangement of admission on tower body, is conducive to air-flow being uniformly distributed in tower.
On the main view plane of tower body, the angle α between each point of bronchial axis and horizontal plane is 5 ° ~ 30 °.Gas can be made to be tilted to down to be entered in tower, not only increases gas at dwell time in the tower, can also prevent in liquid refluence pipe.
In the top plan view of tower body, the angle β between point bronchial axis with the parallel normal plane crossing tower body radial direction is 10 ° ~ 60 °.Be conducive to gas and enter a point bronchus by air inlet pipe, meanwhile, both can prevent angle from crossing atmospheric in tower, form wall stream, can prevent again angle too small air-flow symmetry from entering formation air-flow and liquidate.
