Description
Technical field
The utility model relates to a kind of large-scale exchange column of fixed bed.
Background technique
Current exchange column of fixed bed, for diameter in Φ 800-2600mm, diameter is small, highly in 8200-12000mm, occupies
Height space is big, and is limited by the structures such as the upper and lower distributor of cloth liquid and the ellipse head of lower part pressure-bearing, and maximum throughput is only
In 15m3/h -140m3/h；Because in the presence of being limited to, liquid distribution is uneven, mass-transfer efficiency is low, resin easily leaks and clean maintenance difficulty
The problems such as, more minor diameter exchange columns need to be added, a large amount of valves and accessory must be equipped with, complex operation takes up a large area,
Equipment and construction investment expense are larger, and cost improves, and not only influence the work of whole system, but also also create waste.
Exchange column of fixed bed has the following problems at present:
Inlet distribution device and lower draining distribution apparatus use carrier ring to add water cap on 1., prevent resin in absorption, elution

Diameter Φ 2400mm；Above two structure is at operating pressure 0.3-0.6MPa and resin layer gravity, if device diameters continue to increase,
Partition will be deformed leakage, meanwhile, the water cap on partition easily loosens under forward and inverse water impact, resin leakage.
Upper inlet distribution device is porous distributor pipe and radiation branch pipe, because the upper overhanging diameter of distributor pipe of structure limitation is smaller,
Therefore water distribution range is small, liquid distribution is uneven.
Lower draining distribution apparatus is sieve plate, dome porous plate, operating pressure 0.3-0.6MPa, to make lower part draining point
Cloth apparatus empties liquid, using ellipse end socket, liquid is made to be easy to flow out to centre bottom.Since structure limits, device diameters
Small, onboard the quartz sand by particle size layering is stacked in portion, supports resin.When device diameters Φ 2400 and Φ 2600, increase
Diameter, liquid is not easy uniformly distributed distribution out, bias current, channeling occurs, and resin adsorption, elution, transition rate are uneven, and mass-transfer efficiency is low,
Liquid water quality is unstable out.
2. the processes such as liquid is adsorbed in exchange column, eluted, made the transition, air stirring operate, alternate run, stone are flowed to
Sand layer is easily chaotic, leads to resin leakage.If rearrangement quartz sand layer, heavy workload.If device diameters are larger, resin bed
Deflection is generated, is not easy to level bed, causes resin utilization rate not high, influences the adsorption rate of resin, effective percentage reduces.
At work, worker's heavy workload, transition rate is uneven, and mass-transfer efficiency is low for above-mentioned adsorption column, and liquid water quality is unstable out
It is fixed, while equipment whole height is higher, takes up a large area, investment cost is larger, improves production cost.
