Description
Technical field
The utility model relates to absorption tower technical field more particularly to a kind of vapor absorption towers.
Background technique
Absorption tower is the equipment for realizing absorption operation, is divided into three classes by the gas-liquid form that is in contact.The first kind is gas with gas
Steep plate column, bubble absorbing tower, the stirring bubble absorbing tower of form dispersion in the liquid phase；Second class is that liquid is dispersed with droplet-like
Injector, Venturi tube, spray tower in the gas phase；Third class is the packing material absorbing that liquid is contacted with membranaceous movement with gas phase
Tower and film-falling absorption tower.The type of flow of gas-liquid two-phase generallys use counter-current operation in tower, absorbent with tower top is added from upper and
Lower flowing, contacts with the gas flowed from bottom to top, absorbs the liquid of absorbent and is discharged from tower bottom, and purified gas is from tower
Top row goes out.
Existing vapor absorption tower uses single layer filling-material structure, and cold desalted water and condensed water pass through spray head from vapor absorption tower
Top sprinkling and under, after the steam being passed through when passing through packing layer with lower pipeline carries out heat exchange, be flowed into vapor absorption tower bottom
Portion is flowed out from bottom discharge mouth；And the steam after exchanging heat enters atmosphere by top evacuation port.Since the temperature of condensed water is higher than
Cold desalted water, condensed water itself can dissipate steam, both cold desalted water and condensed water are directly sprayed from vapor absorption tower top
And will lead to packing layer heat when lower mixing and be unevenly distributed, it in turn results in steam " short circuit ", enters vapor absorption tower from lower part
Steam is difficult to ensure good heat exchange effect since packing layer heat is unevenly distributed after entering packing layer, leads to a part
Steam cooling also not yet in effect is just discharged into atmosphere, and exhaust emission is big.
Utility model content
Technical problem to be solved in the utility model and the technical assignment of proposition are improved to the prior art, are provided
A kind of vapor absorption tower solves the vapor absorption tower in current technology in such a way that cold desalted water sprays together with condensed water,
