Description
Technical field
The utility model relates to UF membrane field, particularly relates to a kind of shell and tube forward osmosis membrane module.
Background technology
The step that concentration process is feed separation, water treatment field often runs into, concentration technology main at present mainly contains: have distillation, nanofiltration (NF), counter-infiltration (RO) etc., but the following deficiency that these methods also exist: the way of distillation is concentrated needs the at substantial energy, high cost.Counter-infiltration (RO) or nanofiltration (NF) are a kind of effective ways of gathering trace ion, but are subject to the impact of osmotic pressure, and its enrichment cycles of concentration is limited, and energy consumption is also higher.
Forward osmosis is a kind of novel isolation technics, is described as low energy consumption of new generation, low stain, the desalination of sustainable development and new energy technology.Positive osmosis device utilizes other principle of permeable pressure head to carry out the equipment be separated that dewaters, and the core of equipment is forward osmosis membranes, and the both sides of film are respectively the gateway of two groups of feed liquids of different osmotic.Water enters the high side of osmotic pressure from permeating the side forced down, and the transit dose within the regular hour is weighed and considers that the membrane area of equipment both can calculate the permeable membrane flux of this process.Comparatively speaking, the cycles of concentration of forward osmosis concentrator more than counter-infiltration and nanofiltration high, and forward osmosis can carry out feed liquid at normal temperatures and concentrates, this compared with evaporation technique be one progressive greatly.The shortcomings such as existing forward osmosis membrane module generally adopts plate film assembly, and this modular construction is simple, but also to have effective film area little simultaneously, and concentrated speed is slow.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to design the shell and tube forward osmosis membrane module that a kind of effective film area is large, thickening efficiency is high.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of tubular type forward osmosis membrane module, it is characterized in that: comprise a hollow putamina, described hollow putamina two ends are provided with termination, on two terminations, one is provided with and draws liquid import, another draws liquid outlet, and both sides are provided with liquor inlet and material liquid outlet; Be provided with doughnut forward osmosis membranes in described putamina, described doughnut forward osmosis membranes two ends are provided with sealing head, described doughnut forward osmosis membranes with draw liquid import and draw liquid and export to being communicated with.
Preferably, in described putamina, be furnished with deflection plate, by the baffling of deflection plate, prevent concentration polarization, increase feed liquid and the time of contact of drawing liquid simultaneously, strengthen concentrated effect further.
The utility model can also adopt another mode: a kind of tubular type forward osmosis membrane module, it is characterized in that: comprise a hollow putamina, described hollow putamina two ends are provided with termination, on two terminations, one is provided with liquor inlet, another material liquid outlet, both sides are provided with draws liquid import and draws liquid outlet; Be provided with doughnut forward osmosis membranes in described putamina, described doughnut forward osmosis membranes two ends are provided with sealing head, described doughnut forward osmosis membranes with draw liquor inlet with material liquid outlet to being communicated with.
Preferably, in described putamina, be furnished with deflection plate, by the baffling of deflection plate, increase feed liquid and the time of contact of drawing liquid, strengthen concentrated effect further.
In sum, tubular type forward osmosis membrane module described in the utility model, by forward osmosis membranes being arranged to the form of doughnut, can increase the per membrane area of hollow-fibre membrane greatly, increases thickening efficiency, reduces production cost.
Accompanying drawing explanation
Fig. 1 is tubular type forward osmosis membrane module structure schematic diagram described in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of tubular type forward osmosis membrane module, comprise a hollow putamina 10, termination, hollow putamina 10 two ends first 101 and the second termination 102, wherein the first termination is provided with and draws liquid import 103, second termination is located at and draws liquid outlet 104, both sides are provided with liquor inlet 105 and material liquid outlet 106; Be provided with doughnut forward osmosis membranes 11 in putamina 10, doughnut forward osmosis membranes 11 two ends are provided with sealing 12, described doughnut forward osmosis membranes 11 with draw liquid import 103 and draw liquid and export 104 to being communicated with; In addition, in putamina 10, be furnished with deflection plate 13, by the baffling of deflection plate 13, prevent concentration polarization, increase feed liquid and the time of contact of drawing liquid, strengthen concentrated effect further.
During concrete use, material liquid enters from liquor inlet, draw liquid enters in doughnut forward osmosis membranes through drawing liquid import simultaneously, high owing to drawing liquid osmotic pressure, hydrone is permeated to drawing liquid by material liquid through forward osmosis membranes, and then reach the object being issued to high power enrichment materials liquid at low-temperature condition, moisture in feed liquid enters in doughnut forward osmosis membranes through doughnut forward osmosis membranes, feed liquid is obtained concentrated, final concentrated feed liquid flows out through material liquid outlet, reaches concentrated object.The utility model, by forward osmosis membranes being arranged to the form of doughnut, can increase the per membrane area of hollow-fibre membrane greatly, increases thickening efficiency, reduces production cost.
As another implementation of the present utility model, can also by Fig. 1 draw liquid import, draw liquid outlet change to liquor inlet and material liquid outlet respectively, liquor inlet, material liquid outlet change to and draw liquid import and draw liquid outlet, make feed liquid in the membrane flow of doughnut forward osmosis, draw liquid to flow outward at doughnut forward osmosis membranes, reach concentrated object.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
