Description
Technical field
The utility model is related to acetate esterification material mixing field more particularly to a kind of static mixers.
Background technology
In acetate esterification reaction process, there is the unreacted raw alcohol in part together with esterification reaction product, be detached from reaction
System；The unreacted raw material in this part has to recycle in time, and return to esterifier, and esterification could be maintained normal
Acid alcohol material ratio needed for carrying out；Otherwise esterification balance will be destroyed, influences esterification system normal operation；
At present, enterprise is partially disengaged the unreacted raw alcohol of esterification system to this, is returned when recycling waste water from wastewater tower top
Receive this part material, but recovered material is in addition to containing alcohol, also containing more ester and water, it is necessary to be collected into Sewage treatment and keep in
In slot, esterification will can be just returned after excessive moisture content standing separation and is used, it is impossible to accomplish that unreacted raw alcohol returns in time
Esterifying kettle, esterification process are destroyed acid alcohol ratio and become always among adjustment, influence the normal operation of esterification system.
Utility model content
The purpose of this utility model is to provide the static mixers for the organic phase and water phase for being sufficiently mixed high alcohol content.
To achieve the above object, the static mixer of the utility model, it is characterised in that：Including hollow pipe and lattice framing,
The lattice framing is staggered in hollow pipe, and the hollow pipe both ends are respectively organic phase entrance and organic phase outlet, institute
It states hollow pipe and is equipped with water phase entrance close to the side of organic phase inlet side.
Preferably, the lattice framing two is one group, and every group of lattice framing is arranged in a crossed manner, and infall connection is fixed.
Further, every group of lattice framing is arranged in a crossed manner, and a lattice framing one end connects hollow pipe organic phase inlet side
The upper wall of inner wall, the lower wall of other end connection organic phase outlet side inner wall, one end connection hollow pipe of another lattice framing have
The lower wall of machine phase inlet side inner wall, the upper wall of other end connection organic phase outlet side inner wall.
Further, between several groups of lattice framings two-by-two side by side, and connect fixation.
Further, washing cooling device and water oil quantizer are further included, the organic phase outlet is connected by washing cooling device
It is connected to water oil quantizer.
Preferably, the lattice framing is metal material.
The utility model, mainly have the advantage that：
1st, oil phase and water phase contact area are increased, oil phase is changed and situation is simply mixed in the duct with water phase, make water
Mutually washing extraction efficiency higher；
2nd, it is angled with fluid flow direction between lattice framing and lattice framing.Fluid is ensured by cross one another lattice framing
Continuous crisscross motion between high viscosity fluid ensures the fluid redistribution at each position in pipe and efficient mixing,
Avoid any waller effect simultaneously.The mixer X-bracing structure makes material form laminar flow effect, but also mixer
Itself there is self-cleaning, the conversion of material can be realized by very short mixing distance, material waste degree is down to
It is minimum.Mixer realizes shortest mixing distance and reaches outstanding mixed effect.Since flow velocity is relatively low, mixer is to material
Shearing force is relatively small.
3rd, surface tension is overcome to need higher shearing force, so as to fulfill dispersed phase with smaller drop（Or bubble）Uniformly
Be distributed in entire tube section.Vapour phase or Acceptor flow point are dissipated by cross one another lattice framing, reduce what metal showed
Viscosity differences；Perfection is suitable for smaller droplets size distribution, larger load adjustment and relatively short mounting distance.
Description of the drawings
Fig. 1 is the static mixer structure schematic diagram of the present apparatus.
Fig. 2 is the application system figure of the present apparatus.
Fig. 3 is the sectional view of A-A in Fig. 1.
In figure：1 is lattice framing, and 2 be hollow pipe, and 3 be water phase entrance, and 4 be organic phase entrance, and 5 be organic phase outlet, and 6 are
Washing cooling device, 7 be water oil quantizer.
Specific embodiment
Such as Fig. 1, the static mixer of the utility model is mainly made of hollow pipe 2 and lattice framing 1, and lattice framing 1 is arranged on sky
In heart pipeline 2, lattice framing 1 two is one group, wherein 1 one end of lattice framing connects 2 organic phase entrance of hollow pipe, 4 side inner wall
Upper wall, the other end connect the lower wall of 5 side inner wall of organic phase outlet, one end connection 2 organic phase of hollow pipe of another lattice framing 1
The lower wall of 4 side inner wall of entrance, the other end connect the upper wall of 5 side inner wall of organic phase outlet.Multigroup 1 mutual close apposition of lattice framing
It is arranged in hollow pipe 2, and interconnects fixation, the contact area of increase water oil mixing, as shown in Figure 3.Meanwhile the present apparatus
Organic phase outlet 5 water oil quantizer 7 is connected to by washing cooling device 6, as shown in Figure 2.
The present apparatus in actual use, in acetate esterification reaction process, will be enriched in the enrichment of product tower upper tower section
The organic phase of high alcohol content enters from the organic phase entrance 4 of hollow pipe 2 in static mixer.Meanwhile by Sewage treatment tower tower
The pure water at bottom is passed through from water phase entrance 3 in hollow pipe 2.
Organic phase and water phase are met mixing in hollow pipe 2, and are worn between the lattice framing 1 to gather in hollow pipe 2
It crosses, due to the lattice framing 1 to cross one another densely covered in hollow pipe 2, the contact area of organic phase and water phase greatly increases.Lattice framing 1 with
It is angled with fluid flow direction between lattice framing 1, fluid by cross one another lattice framing 1, ensure that high viscosity fluid it
Between continuous crisscross motion, ensure the fluid redistribution at each position in pipe and efficient mixing, while avoid any
Waller effect.The structure of X-bracing 1 makes material form laminar flow effect in hollow pipe 2, but also mixer has in itself
There is the function of self-cleaning, the conversion of material can be realized by very short mixing distance, material waste degree is minimized.It is logical
Cross the viscosity differences that cross one another lattice framing 1 shows organic phase and Aqueous dispersions, reduction metal.
After mixed material after hybrid extraction is cooled down by washing cooling device 6, divided into water oil quantizer 7
Layer, the water phase containing raw alcohol enter Sewage treatment tower, and the extraction feed alcohol extracted returns to reaction kettle of the esterification, complete alcohol and follow
Ring.
