Abstract
The utility model discloses a vacuum membrane distillation water treating device. The treating device comprises a feed liquid tank; the feed liquid tank is communicated with the heat detection membrane side of a membrane unit sequentially through a peristaltic pump, a flow meter and a heating tank; the cold detection membrane side of the membrane unit is communicated with the feed liquid tank; the hot water outlet of the membrane unit is communicated with a condensing pipe; the condensing pipe is communicated with a permeated liquid collecting tank; the permeated liquid collecting tank is connected with a vacuum pump; the condensed gas outlet of the membrane unit is communicated with the inlet of a condensing tank; and the outlet of the condensing tank is communicated with the condensed gas inlet of the condensing pipe through the peristaltic pump. A separated substance is heated by the heating tank and then passes through the interior of the membrane filaments of the membrane unit; the outer side of the membrane filaments, namely the cavity of the whole membrane unit, is vacuumized through the vacuum pump, so that the transfer of steam forms differential pressure at the two membrane sides of the membrane unit; a single gaseous substance is produced at the vacuum side; the gaseous substance is condensed into liquid through the condensing tank; the liquid is collected by the permeated liquid collecting tank; as a result, solution concentration and separation can be realized; and the vacuum membrane distillation water treating device disclosed by the utility model has the advantages of being capable of realizing permeable evaporation and membrane distillation and separation.
Description
Technical field
The utility model relates to a kind of water treatment facilities, is specifically related to a kind of vacuum membrane distillation water-treatment plant.
Background technology
The film distillation is the membrane separating method that membrane process is combined with still-process, up to the present, has developed the multiple film distillating method, such as direct contact membranes distillation, Air Gap Membrane distillation, the distillation of purging air film, permeable membrane distillation and vacuum membrane distillation.Vacuum membrane distillation has been obtained valuable achievement in research in many fields as a kind of novel membrane separation technique.The vacuum membrane distillation technology with its unique advantage process in desalinization, the aqueous solution, the fields such as solution is concentrated, the preparation of ultra-pure water, environmental protection are widely used.There is short, the shortcoming such as power consumption is higher, efficient is low equipment life in present manufacturing technology, and the water quality requirement to water inlet is also higher in addition, need carry out the preliminary treatment in early stage.

Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
With reference to accompanying drawing, a kind of vacuum membrane distillation water-treatment plant, comprise material fluid bath 1, the outlet of material fluid bath 1 is successively by the first peristaltic pump 2, flowmeter 3, the heat of heating tank 4 and membrane module 5 is surveyed face and is communicated with, the cold survey face of membrane module 5 and the entrance of material fluid bath 1 are communicated with, the first entrance of the hot water outlet of membrane module 5 and condenser pipe 6 is communicated with, first of condenser pipe 6 exports and sees through liquid feeder 7 and is communicated with, see through liquid feeder 7 and are connected connection with vavuum pump, the condensing gas outlet of condenser pipe 6 and the entrance of condensate tank(trap) 9 are communicated with, and the outlet of condensate tank(trap) 9 is communicated with by the condensing gas entrance of the second peristaltic pump 10 and condenser pipe 6.
Operation principle of the present utility model is:
The separated material of material fluid bath 1 passes through from the film silk inside of membrane module 5 after heating through heating tank 4, and namely vacuumize by vavuum pump 8 in the chamber of whole membrane module 5 in the outside of film silk, thereby form the transmission steam pressure difference in the film both sides of membrane module 5, produce single gaseous material at inlet side, be condensed into liquid through condensate tank(trap) 9, and collected seeing through liquid feeder 7, thereby realize the concentrated of solution and separate.
