Description
Technical field
The present invention relates to a kind of acetic acid extraction equipment, relate in particular to a kind of stirring packed tower for the acetic acid extraction equipment.
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 pollutes the environment, and has wasted the acetic acid resource.Because acetic acid and water are less to volatility, therefore available abstraction technique extracts acetic acid from acetic acid wastewater, realizes the maximum using of resource, has also protected environment simultaneously.
Existing acetic acid extraction equipment is in the polymerization of fluid drops that makes extract and raffinate and separation process, usually adopt rotating disk drop to be merged and then separation, but be to use rotating disk can make extract and raffinate axial backmixing, be not easy to better extract be separated with raffinate.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of simple in structure, packed tower that can prevent extract and raffinate axial backmixing is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of stirring packed tower for the acetic acid extraction equipment, comprise tower body, described tower body bottom is provided with extract entrance and raffinate outlet, described tower body top is provided with extract outlet and raffinate entrance, it is characterized in that: axially be provided with some layers of wire packing and rotating shaft in the described tower body, described rotating shaft runs through described wire packing, and described rotating shaft is provided with several and stirs lodicule.
In a preferred embodiment of the present invention, further comprise in the rotating shaft between every two-layer described wire packing being equipped with two described stirring lodicules.
In a preferred embodiment of the present invention, comprise that further described two stirring lodicules all are obliquely installed in described rotating shaft, described two incline directions that stir lodicules are opposite.
In a preferred embodiment of the present invention, the voidage that further comprises mesh on the described wire packing is 92%～99%.
In a preferred embodiment of the present invention, comprise that further the outlet of described extract entrance and described extract is arranged on described tower body the same side, described raffinate outlet and described raffinate entrance all are arranged on the opposite side of described tower body.
In a preferred embodiment of the present invention, comprise that further the outlet of described extract entrance and extract is higher than described raffinate outlet and raffinate entrance respectively.
In a preferred embodiment of the present invention, comprise that further described tower body inner bottom part is provided with bearing fixed seat, described rotating shaft and described bearing fixed seat are rotationally connected.
The invention solves the defective that exists in the background technology, the stirring packed tower for the acetic acid extraction equipment of the present invention, simple in structure, can make drop fully mix merging, in extract and the raffinate separation process axial backmixing, good separating effect can not take place.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 10, tower body, 11, the extract entrance, 12, the raffinate outlet, 13, the extract outlet, 14, the raffinate entrance, 20, wire packing, 30, rotating shaft, 40, stir lodicule, 50, bearing fixed seat.
The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of stirring packed tower for the acetic acid extraction equipment, be used for making the drop of extract and raffinate to merge, after the stirring, light any extract and heavy any raffinate separated, the columned tower body 10 that comprises hollow, the bottom of tower body 10 is provided with extract entrance 11 and raffinate outlet 12, the top of tower body 10 is provided with extract outlet 13 and raffinate entrance 14, tower, axially be provided with some layers of wire packing 20 and rotating shaft 30 in 10, rotating shaft 30 runs through wire packing 20, and rotating shaft 30 is provided with several and stirs lodicule 40.Drive lodicule 40 by rotating shaft 30 and stir, the drop of extract and raffinate is merged, wire packing 20 can make the gently extract come-up of a bit, and the raffinate that weighs any sinks, and realizes separating.
For the drop that makes extract and raffinate mixes, in the rotating shaft 30 between every two-layer wire packing 20, all arrange two and stir lodicule 40, two are stirred lodicule 40 and all are obliquely installed in rotating shaft 30, and two incline directions that stir lodicule 40 are opposite, wherein a slice stirs lodicule 40 towards tower body 10 bottom angled, another sheet stirs lodicule 40 and tilts towards tower body 10 tops, can make the drop of extract and raffinate abundant.
For mixed extract is separated with raffinate, between the voidage of the mesh control 92%～99%, the voidage of mesh is 98% on the wire packing 20 among the present invention on the wire packing 20, can make the gently extract come-up of any preferably, the raffinate that weighs any sinks, and can axially not go up back-mixing.
Because gently the extract of any can float, and the raffinate that weighs any can sink, extract entrance 11 and extract outlet 13 can be arranged on tower body 10 the same sides, raffinate outlet 12 and raffinate entrance 14 all are arranged on the opposite side of tower body 10, and make extract entrance 11 and extract outlet 13 be higher than raffinate outlet 12 and raffinate entrance 14 respectively, relative mobile being convenient to extract and raffinate being axial.
Rotating shaft 30 among the present invention is arranged in the tower body 10 by bearing fixed seat 50, specifically bearing fixed seat 50 can be fixed on the bottom in the tower body 10, rotating shaft 30 and bearing fixed seat 50 are rotationally connected, by motor-driven rotatable shaft 30, rotating shaft 30 are driven stir lodicule 40 stirrings.
Stirring packed tower for the acetic acid extraction equipment of the present invention, simple in structure, can make drop fully mix merging, in extract and the raffinate separation process axial backmixing, good separating effect can not take place.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine technical scope according to the claim scope.
