Abstract
The utility model discloses an improved large-size internal-cooling ammonia absorption tower which comprises a tower ring, a bubble-cap plate, a cooling water tank, a liquid distributor and a liquid redistributor, wherein the liquid distributor is provided with a gas lift pipe and a downcomer; the tower ring positioned under the cooling water tank is provided with a gas inlet and a liquid outlet; a gasket is arranged between the liquid distributor and the tower ring; and the gas inlet extends towards the inside of the tower to the middle part of the tower, and is arranged downwards to form an ammonia gas distributor. In the utility model, the gasket is added to the bottom of the liquid distributor solves the problem of liquid leakage in the liquid distributor, and enhances the ammonia absorption effect of the dilute ammoniacal brine. The gas inlet extends towards the inside of the tower to the middle part of the tower, and is arranged downwards to form the ammonia gas distributor, thereby solving the problem of liquid leakage since the ammonia gas directly erodes the connecting pipe of the water tank, and uniformly cooling the ammonia gas in the tower through the water tank.
Description
Technical field
The utility model relates to a kind of efficient absorption equipment in the soda ash production process, and the utility model relates in particular to ammonia absorption tower.
Background technology
Ammonia absorption tower is that the refined brine that a kind of use is removed calcium, magnesium and salt slurry absorbs the NH distill from the alkaline filtrated stock
3And CO
2Gas, thereby make intermediate products---the equipment of-ammonial brine, in denomination of invention, be " a kind of large-scale internal cooling type ammonia adsoption tower ", the patent No. is CN03258432.6, the Chinese patent that the applying date is on September 12nd, 2003 discloses a kind of internal cooling type ammonia adsoption tower, this equipment has improved single tower production capacity, with the outer cooling tower simplified in comparison cooling process, improved production efficiency.But occurred that in continuous flow procedure liquid distribution trough leakage, the air inlet of ammonia air inlet cause the problems such as water tank leakage.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of solution leakage problem is provided, and guarantees stable and successional a kind of improved large-scale internal cooling type ammonia adsoption tower of producing.
A kind of improved large-scale internal cooling type ammonia adsoption tower of the present utility model, it comprises tower circle, bubble cap plate, cooling water tank, liquid distribution trough, liquid re-distributor, be provided with air-lift tube and downspout on described liquid distribution trough, have air inlet and liquid outlet on tower circle below being positioned at described cooling water tank, be provided with packing ring between described liquid distribution trough and tower circle, described air inlet extends to the tower middle part and formation ammonia distributor is set downwards in tower.
Increase packing ring in the liquid distribution trough bottom in the utility model and solve liquid distribution trough leakage problem, strengthen light ammonial brine and inhale the ammonia effect.In the utility model device, air inlet is extended to the tower middle part in tower, and form the ammonia distributor downwards, solve because adapter place of the direct erosion water tank of ammonia causes the leakage problem, and make the interior ammonia of tower evenly cooling by water tank.
The accompanying drawing explanation
Accompanying drawing is the structural representation of a kind of improved large-scale internal cooling type ammonia adsoption tower of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of improved large-scale internal cooling type ammonia adsoption tower of the present utility model as shown in drawings, it comprises tower circle 1, bubble cap plate 2, cooling water tank 3, liquid distribution trough 6, liquid re-distributor 7, be provided with air-lift tube 8 and downspout 9 on described liquid distribution trough, have air inlet 4 and liquid outlet 5 on tower circle below being positioned at described cooling water tank, be provided with packing ring 11 between described liquid distribution trough and tower circle, described air inlet extends to the tower middle part and formation ammonia distributor 12 is set downwards in tower.
Internal cooling type ammonia adsoption tower is comprised of a plurality of tower circles 1, and top is washing section; Middle part, for absorption, cooling section, is provided with cooling water tank 3, and has air inlet 4 and liquid outlet 5 on the foundation ring below cooling water tank 3 on its tower body, ammonial brine storage tank 10 can be accepted in the tower bottom.
Refined brine is entered through bubble cap plate by the washing section on top, the NH in washing, absorption tail gas
3And CO
2, then by brine distribution device and salt solution redistributor evenly the salt solution sprinkle is absorbed in middle part, cooling section is arranged in the middle of cooling water tank, gas and liquid drive in the wrong direction, the outside wall surface of cooling water tank, heat transfer and mass transfer carry out simultaneously.
The easy leakage of the liquid distribution trough of original equipment and the edge of equipment connection, light ammonial brine is not had all by the downspout of distributor, make light ammonial brine skewness, the ammonia effect is inhaled in impact, by optimizing distributor designs, increase packing ring in the liquid distribution trough bottom and solve liquid distribution trough leakage problem, strengthen light ammonial brine and inhale the ammonia effect.
After the ammonia of original equipment enters ammonia absorption tower by air inlet 4, because flow velocity is larger, easily erosion water tank adapter place and cause leakage, in the utility model device, air inlet 4 is extended to the tower middle part in tower, and form the ammonia distributor downwards, solution causes the leakage problem because of adapter place of the direct erosion water tank of ammonia, and makes the interior ammonia of tower evenly cooling by water tank.
Claims (1)
