Description
[technical field]
The utility model relates to industrial wastes retracting device, a kind of especially for producing the organic solvent recovery still reclaiming additive in waste liquid from hollow-fibre membrane.
[background technology]
During hollow-fibre membrane is produced, polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP) belong to the conventional polymeric additive to improve film properties, contain a large amount of above-mentioned additive in the production waste liquid of therefore hollow-fibre membrane.Due to the content producing various component in waste liquid simply cannot be determined, so waste liquid cannot directly can be used by secondary, can only reclaim.On the other hand, direct discharge can cause environmental pollution, could reclaim or discharge after having to pass through process.
In prior art, recovery process many employings distillation under vacuum of these additives is to remove moisture in waste liquid and unnecessary solvent dimethylacetylamide (DMAC), the product of decompression distillation is additive mixed liquor, i.e. the mixture of polyethylene glycol and polyvinylpyrrolidone.To be added dose of mixed liquor cools after layering solidifies naturally, and mixture can be divided into two-layer up and down, and upper strata is the mixture of solvent DMAC and PEG, and lower floor is the mixture of solvent DMAC and PVP.By the operating type of hand digging, upper strata (PEG with DMAC mixture) is separated with lower floor's (PVP with DMAC mixture).
This manual work mode labour intensity generally used at present is large, inefficiency and contaminated environment, is badly in need of improving.
Chinese utility model patent CN201120077673.9 discloses a kind of recovery still, can be used for raffinate and reclaims.But the material outlet of this kind of recovery still is fixed position, is usually located at autoclave body bottom or sidepiece.For the production waste liquid of hollow-fibre membrane, due to the uncertainty of waste liquid component, waste liquid reclaim the liquid level layer height in still cannot shortcoming, therefore this kind of have determine liquid outlet position, position and be not suitable for the recovery that hollow-fibre membrane produces organic solvent in waste liquid.
[utility model content]
The purpose of this utility model overcomes present technological deficiency, provide a kind of structure simple, effectively reclaim still reliably, for reclaiming organic additive from hollow-fibre membrane production waste liquid.
To achieve these goals, the utility model provides a kind of organic solvent to reclaim still, comprise kettle and the kettle cover being located at described kettle top, the feed pipe 1 that described kettle cover top is provided with liquor inlet and is attached thereto, the bottom discharge pipeline 5 that described autoclave body bottom is provided with lower floor's material liquid outlet and is attached thereto, the stirring motor 2 being also provided with agitating device 3 in described recovery still and being attached thereto, described kettle is provided with form 6, is also provided with rotary discharge device 4 in the middle part of described kettle.
Preferably, rotary discharge device 4 comprises the worm screw 10 being arranged on outside in the middle part of described kettle and the manual turntable 12 be connected with worm screw 10, is provided with the hollow turbine 11 engaged with the helical tooth of worm screw 10, arranges still and expect pipe 9 outward in the middle part of hollow turbine 11 in worm screw 10 side; Also be provided with material pipe 8 in still in the middle part of described kettle, in still, material pipe 8 links with hollow turbine 11, and expects that pipe 9 is communicated with outward with still.
In the utility model, preferably, the axle of worm screw 10 is that vertical direction is arranged; The axle of hollow turbine 11 is vertical with the axle of worm screw 10.
In the utility model, manual turntable 12 is located at upper end or the lower end of worm screw 10.
According to one preferred embodiment, rotary discharge device 4 is mechanically connected by the outer wall of worm screw fixture 13 with described kettle.
Material pipe 8 has bending section 15 being in the position in kettle in still.
In the utility model, form 6 length is from autoclave body bottom until kettle top.
Preferably, described kettle outside is also provided with heating device 7.
More preferably, described heating device is clamping device, oil oven accompanies hot device, steam tracing device or heating tape.
Above-mentioned organic solvent reclaims still and can be used for producing waste liquid from hollow-fibre membrane reclaiming additive, and the method reclaiming additive comprises the following steps:
(1) in recovery still, put into hollow-fibre membrane and produce waste liquid, open the heating device and agitating device that reclaim still, make the hollow-fibre membrane in recovery still produce waste liquid holding temperature 50-90 DEG C, fully stir;
(2), after stopping stirring, maintain hollow-fibre membrane and produce waste liquid temperature 50-90 DEG C of 24-48 hour;
(3) observing hollow-fibre membrane by the form of described recovery still and produce waste liquid layering, discharging upper strata feed liquid from being positioned at the top discharge mouth reclaimed in the middle part of still;
(4) lower floor's feed liquid is discharged from lower floor's material liquid outlet.
Wherein, the production waste liquid of step (1) contains 30%-80% dimethylacetylamide by weight, and surplus is the mixture of polyethylene glycol and polyvinylpyrrolidone.
From hollow-fibre membrane produce waste liquid reclaim additive time, owing to producing containing multiple organic principle in waste liquid, under field conditions (factors) can layering gradually, but often occur there will be can not the situation of layering completely, degeee of stratification and time are all uncontrollable.Additive recovery effectively can be realized by the recovery still still with form and rotary discharge device of the present utility model, in conjunction with the companion's heat and the agitating function that reclaim still, by the layered position of the clear resolution levels of form, by the design of rotary discharge device, the position of one end in the interior still of expecting pipe of still can be changed, to adjust discharging opening to correct position.Receive upper materials by rotary discharge device, by bottom discharge conduit acceptor lower floor material, effectively realize the separation completely of levels material.
Recovery still of the present utility model can be guaranteed not introduce impurity in the process of recovered material or material leaks, and guarantees security.
