Description
Technical field
The utility model relates to a kind of injection apparatus, particularly the multistage multiple dimensioned injection apparatus of a kind of liquid column tower.
Background technology
Common desulfurizer has the types such as spray column, packed tower, JBR tower, liquid column tower (being fluid column formula desulfurizing tower).Wherein the be bullied impact of flow point cloth inequality of spray column desulfuration efficiency is larger, and the energy consumption of slurry circulating pump is large.Packed tower is easily blocked, needs fixed time cleaning to upgrade filler, and maintenance cost is high.The JBR tower exists simultaneously that the absorption process power consumption is excessive, flue-gas temperature reduces too many, equipment and need make antiseptic shortcoming.Fluid column formula desulfurizing tower is newer a kind of wet desulphurization mode.It can reduce investment, saves the energy, and simply is easy to safeguard, has embodied that it is simple in structure, low cost of manufacture, treating capacity is large and the operation and maintenance expense is few, and high efficiency, good antiscale property and the advantage such as easy to control now have been widely used in industrial circle.
Conventional fluid column formula desulfurizing tower all adopts the single-stage spray, namely adopts the spray column of sustained height to spray, and desulfuration efficiency is lower, can improve running cost in addition.
The utility model content
The purpose of this utility model is, provides a kind of liquid column tower multistage multiple dimensioned injection apparatus.The utility model can form Multi-layer sprinkling, and desulfuration efficiency is higher, can also reduce running cost.
The technical solution of the utility model: the multistage multiple dimensioned injection apparatus of a kind of liquid column tower is characterized in that: comprise tower body, the tower body upper end is provided with exhaust pass, and the bottom is provided with inlet flue duct; Be provided with slurry pool, liquid distribution trough and demister layer in tower body from bottom to top, liquid distribution trough connects slurry pool through pipeline, and pipeline is provided with circulating pump, and liquid distribution trough is provided with several spray columns that highly differs, and spray column is provided with nozzle.
In the multistage multiple dimensioned injection apparatus of aforesaid liquid column tower, the described spray column that several highly differ comprises the high spray column at the center of being arranged on, and high spray column both sides are provided with middle spray column and the low spray column that is crisscross arranged.
In the multistage multiple dimensioned injection apparatus of aforesaid liquid column tower, described high spray column height is 1.5m-1.8m.
In the multistage multiple dimensioned injection apparatus of aforesaid liquid column tower, described middle spray column height is 1m-1.2m.
In the multistage multiple dimensioned injection apparatus of aforesaid liquid column tower, described low spray column height is 0.3m-0.5m.
In the multistage multiple dimensioned injection apparatus of aforesaid liquid column tower, on described high spray column, large hole nozzle is set; On described middle spray column, middle hole nozzle is set; On described low spray column, little hole nozzle is set.
In the multistage multiple dimensioned injection apparatus of aforesaid liquid column tower, described inlet flue duct is provided with water-blocking groove.
Compared with prior art, the utility model sprays by the spray column that highly differs, and also can the nozzle of different model be set on the spray column of differing heights, makes and form successively multilayer in the tower body space, drips the drop dense layer that radial sector increases.Namely form a plurality of liquid curtain layers on differing heights, and the liquid-drop diameter of lower floor is little, upwards successively increases, and realize quasi-continuous, multiple dimensioned multistage mass transport process, and total height only is equivalent to the mass-transfer zone height of single-stage liquid column tower; The fine droplets that while can be carried middle low layer mass-transfer zone secretly due to flue gas is up, when passing through high-rise drop district, high-rise larger drop namely begins to catch little droplet, and the mist entrainment of gas phase is increased, to reach the purpose that reduces equipment investment and running cost, improved simultaneously desulfuration efficiency.Through testing: at identical SO
2Under entrance concentration, compare with the single-stage liquid column tower, the desulfuration efficiency of multistage multiple dimensioned liquid column tower improves 20%.(2) under identical liquid-gas ratio, liquid column tower is compared with spray column, and its desulfuration efficiency improves 15.17%
