Abstract
The invention relates to a test apparatus for hollow fiber membrane inside-out water permeable amount. When the test apparatus performs a test process, a material supply pump is adopted to drive a liquid in a material liquid circulation barrel to perform circulation flow, and pressure difference in the whole pipeline of the apparatus is controlled so as to simulate the working scene of the hollow fiber membrane during actual running and determine the inside-out water permeable amount, wherein the running process of the apparatus is simple, the measurement process is convenient, and the measurement value is accurate. According to the present invention, a water sample requiring detection or a material liquid having a certain molecular weight is added to the material liquid circulation barrel, it is ensured that various pipelines have the correct connections and no water leakage is generated, the material supply pump is opened, the material can return to the material liquid circulation barrel through the internal of the hollow fiber membrane along connection pipes under the effect of the material supply pump, a pressure control valve is adjusted, reading of pressure gauges are changed, the adjustment is performed until achieving the required test pressure, the test is performed, the water penetrates through the pore of the hollow fiber membrane, permeates the outer portion of the membrane fibers, and converges into drops under the pressure effect, and the permeating liquid within a certain time is collected through a permeating liquid weighing cup so as to calculate the hollow fiber membrane water permeable amount.

Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is embodiment of the present invention overall structure schematic diagram.
As the preferred embodiment of the present invention, on the tube connector of hollow-fibre membrane (4) both sides, Pressure gauge (2) is all installed, the measurement range of Pressure gauge (2) is 0.05～0.1 MPa, for detection of the transmembrane pressure of hollow-fibre membrane.
In the process of the permeable amount of mensuration tunica fibrosa, need to be with reference to the pressure in hollow-fibre membrane (4), the parameter of reading by the Pressure gauge (2) of installing on the both sides tube connector at hollow-fibre membrane (4), the force value of asking for its mean value and draw, its accuracy is higher, can make last measurement structure more accurate.
As the preferred embodiment of the present invention, on tube connector right side, be also provided with pressure-control valve (6), for adjusting device internal pressure balance.
As the preferred embodiment of the present invention, be also provided with the bracing frame that supports each Pressure gauge (2).
As the preferred embodiment of the present invention, is also putting through penetrating fluid weighing cup (7) bottom.
This device, in the time testing, first adds water sample to be measured or the feed liquid containing certain molecular weight in feed liquid circulation barrel (8), and it is correct, water-tight to guarantee that each pipeline connects.Then, open charging pump (1), under the effect of charging pump (1), liquid can be got back to feed liquid circulation barrel (8) by the inside of hollow-fibre membrane along tube connector.Regulate pressure-control valve (6), the registration of Pressure gauge (2) can change, and is adjusted to required test pressure and tests.
Under the effect of pressure, water can see through the aperture of hollow-fibre membrane and be penetrated into film silk outside and pool and drip, collect the liquid that sees through in certain hour by penetrating fluid weighing cup (7), just can calculate according to formula the permeable amount (Water Permeability, W.P.) of hollow-fibre membrane.
Water sample to be measured is penetrated into outside from the inner side of hollow-fibre membrane, transmembrane pressure is to discharge the pressure-control valve (6) of side by adjusting to approach, and reading is the mean value of two Pressure gauges (2) reading, and basic controlling is at 0.05MPa.
W.P.= V/（π·d·l·t）
V for the permeable volume of institute's minute inner membrance silk, unit be L; D by the internal diameter of survey film silk, unit is m; L is by being surveyed membrane fiber length, and unit is m; T is test a period of time used, and unit is h; π is pi, and its value is 3.14.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the modification that these are equal to or replacement are all included in the application's claim limited range.
