Abstract
The utility model discloses a sweep gas membrane distillation device. The sweep gas membrane distillation device comprises a charging tank, a heating device, a delivery pump, a flowmeter, a hollow-fiber membrane distillation component, a blower, a water production tank and a cooling device, wherein hollow-fiber membranes are mounted in the hollow-fiber membrane distillation component. The sweep gas membrane distillation device is characterized in that the hollow-fiber membranes are hydrophobic polyvinylidene fluoride hollow-fiber membranes with fiber linings. In conclusion, the membrane distillation device adopting the technical scheme has the following advantages: the hydrophobic polyvinylidene fluoride hollow-fiber membranes with fiber linings have the advantages of big flux, good separation effect, no fiber breakage and the like; energy is saved because thermostatic heating can be realized by adopting industrial waste heat, water vapor and the like; and sweep gas is uniformly distributed in the hollow-fiber membranes, so that water vapor is prevented from being condensed on the hollow-fiber membranes, and accordingly, a great amount of water can be produced by water vapor.

Background technology
The film distillation is the film separation process that membrane separation technique combines with still-process, the newcomer in the membrane separation technique big family, it adopts hydrophobic microporous barrier, and the temperature difference that exists with the film both sides and the water vapor pressure that causes is poor as mass transfer force realizes the concentrated of solution.Film distillation have separative efficiency high, to advantages such as the mechanical performance requirement of film and material liquid interphase interaction and film are low, and in normal pressure and the lower operation of lower temperature, have that loss of effective components is few, cycles of concentration is high, the advantage such as energy-conservation (can use industrial waste heat), be particularly suitable for the concentrated of solution, in the concentrated field of Chinese medicine extract good application prospect arranged.
At present, four kinds of different film distillation procedure modes of development place comprise that the distillation of support contact membranes, gap membrane distillation, gas are swept the distillation of formula film and the vacuum type film distills.All there are some problems such as energy consumption is high, efficient is low, reliability is low in above-mentioned four kinds of films distillation mode.Although simple such as direct contact membranes distillation process equipment, because Cooling and Heat Source directly contacts, make the equipment operation energy consumption higher, and easily produce hydrophobic membrane hydrophiling leakage problems; Although vacuum type film distillation membrane flux is high, and is higher to system requirements.Gap membrane distillation is gentle sweeps the distillation of formula film and then exists flux lower.Therefore, how the flux of Effective Raise film distillation reduces investment and operating cost, obtains present economic benefit and social benefit, is the prerequisite whether film distillation technology can industrialization uses.
Summary of the invention
For the problems referred to above, the purpose of this utility model is the shortcomings such as high for the film distillation technology energy consumption, that flux is low, provides a kind of flux high distillation device.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of gas is swept the formula distillation device, comprise head tank, heater, dehvery pump, flowmeter, hollow-fibre membrane distillation assembly, air blast, product water pot, cooling device, in the described hollow-fibre membrane distillation assembly hollow-fibre membrane is installed; Described head tank, dehvery pump, flowmeter links to each other with hollow-fibre membrane distillation assembly charging aperture by feed pipe, described hollow fiber film assembly discharging opening is connected with head tank by concentrated pipeline, described heater is located on the head tank, an end links to each other with the infiltration gas outlet in the hollow-fibre membrane interior conduit two ends in the described hollow-fibre membrane distillation assembly, one end links to each other with gas feed, described gas feed links to each other with air blast by admission line, the infiltration gas outlet links to each other with the product water pot by the steam pipeline, and described cooling device is located on the steam pipeline; It is characterized in that: described hollow-fibre membrane is the hydrophobicity Pvdf Microporous Hollow Fiber Membrane of liner fiber.
Further, described doughnut membrane aperture is the 0.01-0.5 micron.
In sum, adopt technique scheme, adopt distillation device described in the utility model, have the following advantages:
1) to have a flux large for the hydrophobicity Pvdf Microporous Hollow Fiber Membrane of liner fiber, good separating effect, the advantage such as fracture of wire not;
2) energy-conservation, heated at constant temperature can adopt industrial exhaust heat, steam heating etc.;
3) purge air-flow and be evenly distributed in hollow fiber film thread inside, avoided the condensation of steam on hollow-fibre membrane, so the steam aquifer yield is large.
