Power, realizes the concentration of solution.Membrane Materials have separative efficiency it is high, to film and the mechanical performance of material liquid interphase interaction and film
It is required that low advantage, and the lower operation under normal pressure and lower temperature, with loss of effective components it is few, cycles of concentration is high, energy-conservation (can
To use industrial waste heat) etc. advantage, be particularly suitable for the concentration of solution, Chinese medicine extract concentration field have good application
Prospect.
At present, four kinds of different Membrane Materials modes of operation at development, including support contact Membrane Materials, gap membrane steam
Evaporate, sweep gas membrane disillation and vacuum type Membrane Materials.Vacuum membrane distillation is easy to operation, but higher to the hydrophobicity requirement of film, uses
Time one is grown, and the hydrophobicity of film is gradually deteriorated, and its concentrated effect will have a greatly reduced quality, and this has had a strong impact on the use longevity of membrane module
Life, increased use cost.
The content of the invention
Regarding to the issue above, the purpose of this utility model is to provide a kind of service life that can improve membrane module, drop
The distillation device that the gentle formula of sweeping of vacuum of low use cost is combined.
To reach above-mentioned purpose, the technical scheme that the utility model is proposed is：What a kind of gentle formula of sweeping of vacuum was combined
Distillation device, including head tank, heater, dehvery pump, First Heat Exchanger, membrane component；Described membrane component
It is provided with charging aperture, discharging opening, gas feed and gas vent；Described head tank, dehvery pump, First Heat Exchanger is by charging
Pipeline is sequentially connected with membrane component charging aperture, and described membrane component discharging opening is connected by concentrating pipeline with head tank
Connect, described heater is on head tank；It is characterized in that：Described membrane component gas vent is connected by pipeline
The liquid outlet for having a gas-liquid separation device, described gas-liquid separation device connects head tank, gas-liquid separation device by pipeline
Gas vent the second heat exchanger, vacuum batch can are sequentially connected by pipeline, be connected with a vavuum pump on described vacuum batch can；
Described gas feed connects compressed air accumulator by pipeline.
Preferably, described membrane component is doughnut Membrane Materials component, described doughnut Membrane Materials component
Hydrophobic hollow fiber film is inside installed.
Preferably, described hydrophobic hollow fiber film is the hydrophobicity Pvdf Microporous Hollow Fiber Membrane of liner fiber；
Described hydrophobic hollow fiber membrane aperture is 0.01-0.5 microns.
In sum, using above-mentioned technical proposal, the Membrane Materials that the gentle formula of sweeping of vacuum described in the utility model is combined
Device, with advantages below：
1) it is combined using vacuum membrane distillation and sweep gas membrane disillation, is first concentrated using vacuum membrane distillation, when film group
When film hydrophobicity in part is deteriorated, it is Membrane Materials to be swept using gas, considerably increases the service life of membrane module, reduces and is produced into
This；
2) the hydrophobicity Pvdf Microporous Hollow Fiber Membrane of liner fiber has flux big, good separating effect, not fracture of wire etc.
Advantage.
Brief description of the drawings
Fig. 1 is the distillation device structure chart that the gentle formula of sweeping of vacuum described in the utility model is combined.
Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As shown in figure 1, the distillation device that the gentle formula of sweeping of vacuum described in the utility model is combined, including head tank
11st, heater 12, dehvery pump 13, First Heat Exchanger 14, membrane component 15, described membrane component 15 are provided with charging
Mouth 151, discharging opening 152, gas feed 153 and gas vent 154；Described head tank 11, dehvery pump 13, First Heat Exchanger 14
It is sequentially connected with the charging aperture 151 of membrane component 15 by feed pipe, described hydrophobic hollow fiber membrane module 15 discharges
Mouth 152 is connected by concentrating pipeline 16 with head tank 11, and described heater 12 is on head tank 11；Described Membrane Materials
The gas vent 154 of component 15 is connected with a gas-liquid separation device 17 by pipeline, the liquid discharge of described gas-liquid separation device 17
Mouthful by pipeline connection head tank 11, the gas vent of gas-liquid separation device 17 by pipeline be sequentially connected the second heat exchanger 18,
Vacuum batch can 19, is connected with a vavuum pump 20 on described vacuum batch can 19；Described gas feed 153 is connected by pipeline and pressed
Contracting air accumulator 21.
Preferably, described membrane component 15 is doughnut Membrane Materials component, described doughnut Membrane Materials group
Hydrophobic hollow fiber film is installed in part；And described hydrophobic hollow fiber film is the hydrophobicity polyvinylidene fluoride of liner fiber
