Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further：
As Figure 1-Figure 2, liquid distribution trough in a kind of extraction tower described in the utility model, including cylinder 1, cover plate 2,
Secondary liquid distributing board 3, secondary liquid distributing board 6, input duct 5 and fluid passage pipe 4；2, liquid distributing board of the cover plate
3 and secondary liquid distributing board 6 set gradually in cylinder 1 from top to bottom, and cylinder 1 is separated into into upper cavity 7 and lower chamber 8；
One end of input duct 5 is stretched in upper cavity 7 through cover plate 2, other end connection heavy phase liquid conveyance conduit；Liquid distribution
Once liquid distribution holes 9 (as shown in Figure 3) are opened up on plate 3, offer secondary liquid distribution holes 10 on secondary liquid distributing board 6
(as shown in Figure 4)；Multiple fluid passage pipes 4 are provided with cylinder 1, and fluid passage pipe 4 is the circular cone that diameter from up to down expands
Platform shape structure, its upper end open are extended to above cover plate 2, and lower ending opening extends to the lower section of secondary liquid distributing board 6.
Stretch into from the middle part of cover plate 2 in upper cavity 7 one end of the input duct 5.
Liquid distribution holes 9 are with diameter greater than 10 diameter of secondary liquid distribution holes, the number of secondary liquid distribution holes 10
Quantity of the amount more than liquid distribution holes 9.
The plurality of fluid passage pipe 4 is uniformly arranged on 1 cross section of cylinder, liquid distribution holes 9, a secondary liquid point
Cloth hole 10 is uniformly arranged in the surrounding of fluid passage pipe 4 respectively.
7 height of the upper cavity is less than 8 height of lower chamber.
In a kind of extraction tower described in the utility model, the method for work of liquid distribution trough is as follows：
1) liquid distribution trough is arranged in extraction tower, and the heavy phase liquid come from the conveying of heavy phase liquid conveyance conduit passes through feed liquor
Pipeline 5 is entered in upper cavity 7, and is rapidly filled with upper cavity 7；Heavy phase liquid in upper cavity 7 is by a liquid distributing board 3
Liquid distribution holes 9 be flowed in lower chamber 8, realize first uniform；
2) in lower chamber 8, heavy phase liquid continues secondary liquid distribution holes 10 on secondary liquid distributing board 6 to dirty
Dynamic, as the diameter of secondary liquid distribution holes 10 is less than liquid distribution holes 9, heavy phase liquid flowing velocity slows down, lower chamber 8
Volume more than the volume of upper cavity 7, therefore more heavy phase liquids can be taken in；Due to the quantity of secondary liquid distribution holes 10 it is big
In the quantity of liquid distribution holes 9, therefore heavy phase liquid is achievable further uniform；The weight Jing after two liquid distribution holes 10
Phase liquid forms dispersion phase and uniformly flows in tower in light phase liquid；
3) blended with heavy phase liquid by the light phase liquid that extraction tower bottom of towe is entered in tower, during buoyance lift, enter fluid passage upwards
In pipe 4, the fluid passage pipe 4 of truncated cone structure can make light phase liquid higher in the liquid level that top is assembled, so as to realize light, weight
The pre-separation of phase liquid；
4) light phase liquid after liquid distribution trough pre-separation continues up buoyance lift and realizes final point with heavy phase liquid
From the light phase liquid after separation flows under the influence of gravity into bottom of towe from overhead extraction, heavy phase liquid.
Larger-diameter liquid distribution holes 9 are opened up on liquid distributing board 3 uniformly, its effect is to heavy phase
Liquid carries out pre- distribution, and due to the small volume of upper cavity 7, heavy phase liquid is full of upper cavity 7 after entering quickly, it is thus ensured that
From on a liquid distributing board 3, each liquid distribution holes 9 are while trickle, it is ensured that it is uniform that heavy phase liquid is distributed for the first time
Property.
The secondary liquid distribution holes 10 of small diameter are opened up on the secondary liquid distributing board 6 uniformly, heavy phase liquid is by upper
Cavity 7 is further uniformly distributed into after lower chamber 8, can ensure that heavy phase liquid divides in tower after liquid distribution process twice
Cloth is uniform.
The fluid passage pipe 4 is the truncated cone structure that upper diameter is little, lower diameter is big.Due to it is light in extraction tower,
Heavy phase liquid has certain blending, therefore needs the separated space of certain altitude above liquid distribution trough；This practicality is new
In type, blending liquid carries out pre-separation in fluid passage pipe 4, using the fluid passage pipe 4 of truncated cone structure, can make light phase
The liquid level that liquid is assembled at the top of fluid passage pipe 4 is higher, the separation of more conducively biphase liquid.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that this utility model is disclosed, according to this practicality
New technical scheme and its utility model design in addition equivalent or change, should all cover in protection model of the present utility model
Within enclosing.
