The spray column comprises a hollow cylindrical column body; one end of the tower body is provided with a charge end while the other end of the tower body is provided with a discharge end; two raw-material liquid inlets and an extraction phase outlet are formed in the charge end; an extraction agent inlet and an extraction raffinate phase outlet are formed in the discharge end. The spray column used for the acetic acid extracting device is simple in structure, small in size and easy to maintain; when extracting, raw liquid widely contacts with an extraction agent and does not axially return and blend, and an extraction phase and an extraction raffinate phase are dispersed well.

Description

A kind of spray column for the Extraction of Acetic Acid device
Technical field
The utility model relates to a kind of Extraction of Acetic Acid device, relates in particular to a kind of spray column for the Extraction of Acetic Acid device.
Background technology
Acetic acid is very important basic organic, is widely used in producing acetate fiber, the solvent that sprays paint, spices, dyestuff, medicine etc., in chemical process, can produce a large amount of acetic acid wastewaters, directly the discharging acetic acid wastewater, not only pollute the environment, and wasted the acetic acid resource.Due to acetic acid and water less to volatility, therefore available abstraction technique, from acetic acid wastewater, extracting acetic acid, is realized the maximum using of resource, has also protected environment simultaneously.
Spray column structure in existing extraction equipment is more complicated, and volume is large, not easy care.
The utility model content
The utility model has overcome the deficiencies in the prior art, provide a kind of simple in structure, volume is little, be easy to safeguard, material liquid and extractant contact area are large simultaneously, the spray column that effect of extracting is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of spray column for the Extraction of Acetic Acid device, the cylindric tower body that comprises hollow, one end of described tower body is provided with feed end, the other end is provided with discharge end, it is characterized in that: described feed end is provided with material liquid inlet and extraction phase outlet, and described discharge end is provided with extractant inlet and raffinate phase outlet.
In preferred embodiment of the utility model, comprise that further described tower body inside is provided with funnelform diffusion part at described extractant inlet place.
In preferred embodiment of the utility model, further comprise the diameter of the diameter of described discharge end greater than described tower body, between described discharge end and described tower body, be provided with cone shape contraction flow region.
In preferred embodiment of the utility model, comprise that further described material liquid inlet is two, be separately positioned on described extraction phase outlet both sides.
In preferred embodiment of the utility model, comprise that further described raffinate phase outlet is two, be separately positioned on described extractant inlet both sides, described raffinate phase outlet is corresponding with described material liquid inlet, and described extractant inlet is corresponding with described extraction phase outlet.
In preferred embodiment of the utility model, further comprise the diameter of the diameter of described tower body less than described feed end.
The utility model has solved the defect that exists in the background technology, and the spray column for the Extraction of Acetic Acid device of the present utility model is simple in structure, volume is little, is easy to safeguard, in extraction process, material liquid and extractant contact area are large, can axial backmixing, and extraction phase and raffinate phase dispersion effect are good.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
In figure: 10, tower body, 20, feed end, 21, the material liquid inlet, 22, the extraction phase outlet, 30, discharge end, 31, the extractant inlet, 32, the raffinate phase outlet, 40, the diffusion part, 50, contraction flow region.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of spray column for the Extraction of Acetic Acid device, according to gravity, make extraction phase can relatively flow realize two phase countercurrent flow and disperse with raffinate phase, the cylindric tower body 10 that comprises hollow, one end of tower body 10 is provided with feed end 20, the other end is provided with discharge end 30, and feed end 20 is provided with material liquid inlet 21 and extraction phase outlet 22, and discharge end 30 is provided with extractant inlet 31 and raffinate phase outlet 32.
For making extractant in the interior better mixing that contacts with material liquid of tower body 10, can at extractant inlet 31 places, funnelform diffusion part 40 be set in tower body 10 inside, increase extractant and from extractant inlet 31, enter the area of tower body 10 inside, namely increase the contact area of extractant and material liquid.
The diameter of the discharge end 30 in the utility model is greater than the diameter of tower body 10, equally, for making extractant in the interior better mixing that contacts with material liquid of tower body 10, cone shape contraction flow region 50 can be set between discharge end 30 and tower body 10, material liquid is relative with extractant while flowing, through cone shape contraction flow region, material liquid is mixed more fully with extractant; Equally, the diameter of feed end 20 is set to the diameter greater than tower body 10, and the material liquid that injects from larger feed end 20 during through narrower tower body 10, can fully contact with the extractant mixing.
Two material liquid inlets 21 are set on feed end in the utility model and 22, two material liquid inlets 21 of an extraction phase outlet are separately positioned on extraction phase outlet 22 both sides; For making flow relative with raffinate phase of extraction phase, realize two phase countercurrent flow and disperse, at discharge end 30, two raffinate phase outlets 32 and an extractant inlet 31 are set too, two raffinate phase outlets 32 are separately positioned on extractant inlet 31 both sides, and making raffinate phase outlet 32 corresponding with material liquid inlet 21, extractant injection 31 is corresponding with extraction phase outlet 22.
Spray column for the Extraction of Acetic Acid device of the present utility model, simple in structure, volume is little, is easy to safeguard, and in extraction process, material liquid and extractant contact area are large, can axial backmixing, extraction phase and raffinate phase dispersion effect are good.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine technical scope according to the claim scope.
