Technical field
It the utility model is related to technical field of chemical, and in particular to a kind of technique Water Sproading rectifying of BDO
Tower.
Background technology
1,4- butanediol abbreviations BDO is a kind of important organic and fine chemical material.Acetylene-formaldehyde process 1,4- butanediol works
Skill：By acetylene and formaldehyde, ethynylation generates butynediols under catalyst action, and butynediols adds under catalyst action through two steps
Hydrogen generate BDO crude products, BDO crude products through rectifying, be refined into last BDO products.In production, can produce containing a large amount of 1,
The raffinate of 4- butanediol compositions, this reduces the yield of product to a certain extent, not only waste of resource, while the discharge of raffinate
Pollution is also required to solve.
Now on the market there is also the device of BDO in recovery raffinate, in recovery more the technique that uses to be smart
Evaporate, and rectifying column reasonable in design is the key of raffinate recovery process.Common rectifying tower structure includes tower body, multistage filler
Section, tower overhead gas outlet, phegma import, charging aperture, reboiler return tower mouth, bottom of towe discharging opening and remove reboiler mouth, each packing section
Upper end set liquid distribution trough.
Phegma and charging liquid are uniformly distributed on filler surface by liquid distribution trough, form liquid initial distribution.Cause
For in the operation of packed tower, the influence of the initial distribution of liquid to packed tower performance is maximum, therefore liquid distribution trough is most important
Tower internals.
Traditional liquid distribution trough, generally there is the uneven phenomenon of liquid distribution, causes mass-transfer efficiency in actual production
Reduce, the filler at tower center is prevented when serious from wetted.
Utility model content
Therefore, in view of the above-mentioned problems, the process water that the utility model provides a kind of high BDO of organic efficiency returns
Receive rectifying column.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of technique Water Sproading rectifying column of BDO, including tower body, the interior Spaced that is provided with of the tower body are distributed
Packing layer, each packing layer upper end is provided with distributor, and the distributor includes feed tube, it is multiple to be connected with the feed tube
Isocon, the more than two distributing slots not of uniform size being connected with isocon, each distributing slot is in circular and concentric set
Put, the bottom surface of distributing slot is provided with the sieve aperture for being used for liquid outflow, and the circumference side upper end of each distributing slot is provided with side spout hole, lower end
Provided with overflow tooth, the retainer ring for being used for being connected with tower body is provided with positioned at the distributing slot periphery of outmost turns.
Preferably, the retainer ring lower end is provided with the distribution screen cloth parallel with the distributing slot.
Preferably, each distributing slot is set for layering.
Preferably, the distribution screen cloth is in the convex cone-shaped structure in middle part.
By using preceding solution, the beneficial effects of the utility model are：The utility model is using multiple annulars point
The form of cloth groove so that the raffinate inputted by feed tube uniformly, rapidly can be distributed on each distributor, improve distribution effect
Rate, uniformly dripped and be distributed on filler by the sieve aperture of lower surface, and retainer ring is set, prevent raffinate by being flowed during filler
To tower wall, the phenomenon of raffinate skewness is caused to occur；Each distributing slot is layered and set, entering raffinate fashionable can keep enough
Flowing velocity, improve rectifying column pan feeding efficiency, and then improve organic efficiency；Coniform distribution screen cloth is set, makes drippage
Raffinate is falling to have certain buffering when on filler, reduces drop and splashes, improves the operation stability of rectifying column.
Brief description of the drawings
Fig. 1 is the rectifying tower structure schematic diagram of the utility model embodiment；
Fig. 2 is the utility model embodiment structure of distributor schematic diagram；
Fig. 3 is the overlooking the structure diagram of the utility model embodiment distributor.
Embodiment
Describe embodiment of the present utility model in detail below with reference to specific embodiment, whereby to the utility model such as
What application technology means solves technical problem, and the implementation process for reaching technique effect can fully understand and implement according to this.
Embodiment
With reference to figure 1, for the basic structure of rectifying column, a kind of technique Water Sproading rectifying column of BDO, including tower body
1, the tower body 1 is interior to be provided with three layers of packing layer 2 being spaced apart, and each upper end of packing layer 2 is provided with distributor 3；
With reference to figure 2 and Fig. 3, the distributor 3 includes feed tube 31, the multiple isocons being connected with the feed tube 31
32nd, the distributing slot 4 not of uniform size of three to be connected with isocon 32, each distributing slot 4 are horizontal in circular and concentric setting
Section is hollow rectangular configuration, and the bottom surface of distributing slot 4 is provided with the sieve aperture for being used for liquid outflow, the circumference side of each distributing slot 4
Upper end is provided with a plurality of side spout holes 41, and lower end is provided with overflow tooth 42, is provided with and is used for positioned at the periphery of distributing slot 4 of outmost turns
The retainer ring 5 being connected with tower body；Therefore the side spout hole 41 of the distributing slot positioned at outmost turns is arranged on its inside circumference face.
In the present embodiment, each distributing slot 4 is set for layering, and diameter is outwards gradually increased by middle part so that isocon 32 has
There is certain drop, the flow velocity of raffinate can be ensured；
The lower end of retainer ring 5 is provided with the distribution screen cloth 51 parallel with the distributing slot 4, and the distribution screen cloth 51 is in middle part
Convex cone-shaped structure.Raffinate has certain buffering before filler is dropped to by distributing slot 4, especially for by overflow
The raffinate that tooth 42 is fallen, also more can uniformly it be distributed when measuring big.
According to rectifying column size the distributing slot 4 of different numbers can be set, to ensure to divide equally effect in the utility model.
The utility model uses the form of multiple annular spread grooves so that can uniformly, soon by the raffinate of feed tube input
Fast ground is distributed on each distributor, improves distribution efficiency, is uniformly dripped and is distributed on filler by the sieve aperture of lower surface, and set
Retainer ring is put, prevents raffinate from, by flowing to tower wall during filler, causing the phenomenon of raffinate skewness to occur；By each distributing slot point
Layer is set, make raffinate enter it is fashionable can keep enough flowing velocities, improve rectifying column pan feeding efficiency, and then improve recovery effect
Rate；Coniform distribution screen cloth is set, enables the raffinate of drippage falling there is certain buffering when on filler, drop is reduced and splashes,
Improve the operation stability of rectifying column.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
