The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, hollow fiber internal pressure membrane flux testing arrangement of the present utility model, at least has following advantages:
One, hollow fiber internal pressure membrane flux testing arrangement of the present utility model, during the detection of underway hollow fiber film silk, without some hollow-fibre membranes being cast into widgets, as a little ultrafiltration apparatus, detect, while having reduced casting, need the epoxy glue step of curing 12-24 hour that smell is very large, eliminated the bad defect that can leak of casting, direct aquifer yield reading in test process, easy, accurate, quick, accuracy of detection is high.
Two, hollow fiber internal pressure membrane flux testing arrangement of the present utility model, simple in structure, convenient to use, test accurately.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this practical hollow fiber internal pressure membrane flux testing arrangement preferred embodiment.
The specific embodiment
For further setting forth the utility model, be to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, its specific embodiment of hollow fiber internal pressure membrane flux testing arrangement according to the utility model proposes, step, structure, feature and effect thereof are described in detail.
Referring to shown in Fig. 1, is the schematic diagram of this practical hollow fiber internal pressure membrane flux testing arrangement preferred embodiment.The hollow fiber internal pressure membrane flux testing arrangement of this practical preferred embodiment, comprise pressure source 1, be arranged at the pressure regulator valve 2 in pressure source 1 exit, be arranged at the Pressure gauge 3 on pipeline 9, container 7 is received in accurate measuring device 4, the first support 5, the second support 10 and water outlet.
This pressure source 1, provides pressure air, this pressure source 1 through pressure regulator valve 2 by pipeline 9 and accurate container 4 together with.The surface of this precision measuring device 4 is provided with scale, and these precision measuring device 4 lower ends are provided with taphole 6, and this precision measuring device 4 is arranged at the first support 5, and this precision measuring device 4 is transparent or semitransparent.The second support 10 and first support 5 one end, interval are apart from setting.This water outlet receives container 7 to be arranged between this first support 5 and the second support 10.
Utilize above-mentioned hollow fiber internal pressure membrane flux testing arrangement, the pure water flux method of test hollow fiber internal pressure film 8 is as follows: first-selection, hollow fiber internal pressure film 8 one end are penetrated to the taphole 6 of accurate measuring device 4, and the other end is fixed on the second support 10; The deionized water that adds some in accurate measuring device 4, first will be full of deionized water in hollow fiber internal pressure film 8, hollow fiber internal pressure film 8 is fixed on to the second support 10 ends and clamps sealing; Regulate the pressure air of pressure regulator valve 2 given certain pressures, by precision pressure gauge 3, regulating airtight measuring device 4 internal pressures is 0.1MPa, and now hollow fiber internal pressure film 8 has and produces water and ooze out, and the water oozing out splashes into this water outlet and receives container 7; After stable water outlet, start timing, record is the interior deionized water volume of accurate measuring device 4 V0 now, move after one minute and record the interior deionized water volume of accurate measuring device 4 V1, by deionized water volume differences in the unit interval, can try to achieve press mold standard pure water flux in hollow-fibre membrane.
Pure water flux formula is
J: standard pure water flux (L/ (M2.H.bar));
V0 initial water level volume (ml);
V1 is completed rear water level volume (ml);
L: hollow fiber internal pressure film length (cm);
D: hollow fiber internal pressure film internal diameter (cm)
Hollow fiber internal pressure membrane flux testing arrangement of the present utility model, direct aquifer yield reading in test process, easy, accurate, quick, accuracy of detection is high.
