Background technology
Concentration process is the step that feed separation, water treatment field often run into; Main concentration technology mainly contains at present: distillation, nanofiltration (NF), counter-infiltration (FO) etc. are arranged; But the following deficiency that these methods also exist: the way of distillation concentrates needs the labor energy, and cost is too high.Counter-infiltration (RO) or nanofiltration (NF) are a kind of effective ways of gathering trace ion, but receive the influence of osmotic pressure, and its enrichment cycles of concentration is limited, and energy consumption is also higher.
Forward osmosis is a kind of new separation technology, is described as the desalination and the new energy technology of low energy consumption of new generation, low pollution, sustainable development.Forward osmosis equipment is the equipment that utilizes other principle of permeable pressure head to dewater and separate, and the core of equipment is the forward osmosis film, and the both sides of film are respectively the gateway of two groups of feed liquids of different osmotic.The side that water forces down from infiltration gets into the high side of osmotic pressure, and the transit dose in the regular hour is able to weighing 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 is high more than counter-infiltration and nanofiltration, and forward osmosis can carry out feed liquid at normal temperatures and concentrates, and this compares with evaporation technique is a progress greatly.
Summary of the invention
To the problems referred to above, the purpose of the utility model is to design the forward osmosis equipment that a kind of cycles of concentration is high, energy consumption is low.
For achieving the above object, the technical scheme that the utility model proposed is: a kind of forward osmosis equipment, comprise the forward osmosis membrane module, and it is characterized in that: in the described forward osmosis membrane module forward osmosis film is installed; Described forward osmosis film is divided into two parts up and down with the forward osmosis membrane module, has a material liquid import on one sidewall of described top, and has a concentrated solution outlet on another sidewall corresponding with this sidewall; Have one on one sidewall of described lower part and draw the liquid import, and have one on another sidewall corresponding and draw liquid outlet with this sidewall; Described material liquid import links to each other with feedstock pump, head tank through pipeline; Described concentrated solution outlet concentrates pipeline through one and links to each other with head tank; Described draw the liquid import through pipeline with circulating pump, draw flow container and link to each other, described draw the liquid outlet through reflux line with draw flow container and link to each other.
Further, on the pipeline between described feedstock pump and material liquid import flowmeter and Pressure gauge are installed also.
Further, described circulating pump and draw flowmeter and Pressure gauge also are installed on the pipeline between the liquid import.
Further; Described forward osmosis membrane module can be forward osmosis plate film assembly, hollow fiber film assembly, screw rolled membrane module, and corresponding described forward osmosis film is dull and stereotyped forward osmosis film, doughnut forward osmosis film, screw rolling forward osmosis film.
Further, described head tank with draw flow container and can also be installed on the meausring apparatus, and then reach through quality measurement, confirm the purpose of cycles of concentration.
In sum; Adopt above-mentioned forward osmosis equipment; Material liquid circulates in forward osmosis film one side, draws liquid and circulates at forward osmosis film opposite side, because it is high to draw liquid osmotic pressure; Hydrone sees through the forward osmosis film and is permeated to drawing liquid by material liquid, and then reaches the purpose that is issued to the concentrated material liquid of high power at low-temperature condition; Draw liquid in addition and can adopt the salt solution of high concentration or directly adopt seawater, have abundant, the low cost and other advantages of raw material sources.
