Abstract
The utility model relates to rolling type membrane components, in particular to a rolling type membrane wide flow channel flow guide net. The rolling type membrane wide flow channel flow guide net comprises a plurality of longitudinally and parallelly arranged longitudinal ribs, adjacent longitudinal ribs are connected through a plurality of transverse ribs, longitudinal flow channels are formed by adjacent longitudinal ribs, longitudinal sections of the longitudinal ribs are elliptical or symmetrically polygonal, and the transverse ribs are connected in the middle of the ellipse or symmetrical polygon. The rolling type membrane wide flow channel flow guide net has the advantages that the inlet water flow can not be easily blocked, the service life of a membrane is long, the effective utilization area of the membrane is large, and the use efficiency is high. In the field of reuse of recycled water, a reverse osmosis membrane with the inlet water flow guide net can be utilized to achieve dual functions of removing impurities and desalinating, and the present ultrafiltration and reverse osmosis process can be replaced; and in the field of special material separation, a nanofiltration membrane with the inlet water flow guide net can be utilized to complete impurity removing and monovalent salt dehydration removing in one step, and the ultrafiltration and nanofiltration process can be replaced.
Description
Technical field
The utility model relates to rolled membrane module, relates in particular to the wide runner flow-guiding screen of rolled film.
Background technology
Rolled membrane module have the unit volume Intimal area large, do not have the characteristics such as fracture of wire to be widely used in water treatment and technical process field.At first in the pure water preparation field, pending former water is running water or surface water normally in industrial application for rolled film, just directly enters reverse osmosis membrane system through simple preliminary treatment (sand filtration, carbon filter).At present, rolled film also is used in middle water reuse and special separation field.Strict preliminary treatment will be passed through usually because the impurity such as the complicated and common contained suspension of original liquid component and colloid are more in middle water reuse and feed separation field, namely usually passes through hyperfiltration treatment (SDI＜3) and enters afterwards rolled membrane module again.Rolled film in the market is in the defective of middle water reuse and feed separation: 1, water inlet flow channel is narrower, and suspension and colloid easily accumulate in runner, therefore needs through strict preliminary treatment.If the raw water quality fluctuation is very large or preliminary treatment is not strictly carried out, the rolled membrane module runner will be stopped up, obstruction will cause: the pressure reduction of membrane module increases, and aquifer yield reduces, and may will damage membrane module when serious.2, at present the rolled film runner adopts rectangle (shown in accompanying drawing 1, accompanying drawing 2, water inlet flow channel is the rectangle graticule mesh), and it is larger that four angles easily produce the deposition of pollutant and flow-guiding screen and film silk contact area, and the area that effectively utilizes of film silk reduces relatively.
Summary of the invention
Exist water inlet flow channel narrow for existing rolled film flow-guiding screen, film easily stops up, flow-guiding screen and film silk contact area are larger, the film silk effectively utilize the few defective of area, the utility model provides a kind of runner to be difficult for stopping up, what can increase film effectively utilizes area, makes the service efficiency of film, the wide runner flow-guiding screen of rolled film that all be improved service life.
For achieving the above object, the utility model adopts following technical scheme:
The wide runner flow-guiding screen of rolled film, comprise the longitudinal rib that a plurality of parallel longitudinals are arranged, connected by a plurality of horizontal bars between the adjacent longitudinal rib, form vertical runner between the adjacent longitudinal rib, the longitudinal section of described longitudinal rib is oval or symmetrical polygon, and horizontal bar is connected to ellipse or symmetrical polygonal middle part.The longitudinal section be oval or symmetrical polygonal longitudinal rib up and down little, the middle part is large, and is thereby less with film silk contact area, that has improved film effectively utilizes area.Horizontal bar is connected to ellipse or symmetrical polygonal middle part, does not contact with the film silk, also can improve effectively utilizing area and making the water flow turbulization of film, has improved the service efficiency of film.
As preferably, the horizontal bar between adjacent channels is staggered.The staggered reverse osmosis membrane stressed (water of turbulence state vertically puts on the power of film) that makes of horizontal bar is more even, is conducive to protect diaphragm.
As preferably, the spacing between the adjacent longitudinal rib is 0.5cm～10cm.Wide runner is not easy to stop up, and prolongs the service life of film.
The wide runner flow-guiding screen of rolled film of the present utility model has water inlet flow channel and be difficult for to stop up, the long service life of film, film effectively utilize area high, the advantage that service efficiency is high.In middle water reuse field, if adopt the reverse osmosis membrane that comprises this structure water inlet flow-guiding screen, can finish removal of impurities and desalination dual-use function, replace present ultrafiltration+reverse osmosis process; In extraordinary feed separation field, comprise this structure water inlet flow-guiding screen NF membrane if adopt to adopt, the dehydration that can finish removal of impurities and monovalent salt a step removes, and substitutes ultrafiltration+receive nanofiltration technique.

The specific embodiment
Below in conjunction with Fig. 3～6 and the specific embodiment the utility model is described further.
The wide runner flow-guiding screen of rolled film, shown in Fig. 3,4, comprise the longitudinal rib 1 that a plurality of parallel longitudinals are arranged, connected by a plurality of horizontal bars 2 between the adjacent longitudinal rib 1, form vertical runner 3 between the adjacent longitudinal rib 1, the longitudinal section of longitudinal rib 1 is oval, and horizontal bar 2 is connected to oval-shaped middle part.The horizontal bar 2 that adjacent channels is 3 is staggered.Spacing a between the adjacent longitudinal rib 1 is 0.5cm.
The wide runner flow-guiding screen of rolled film, shown in Fig. 5,6, the longitudinal rib 1 that comprises a plurality of longitudinal arrangements, connected by a plurality of horizontal bars 2 between the adjacent longitudinal rib 1, form vertical runner 3 between the adjacent longitudinal rib 1, the longitudinal section of longitudinal rib 1 is symmetrical hexagon, and horizontal bar 2 is connected to symmetrical hexagonal middle part.The horizontal bar 2 that adjacent channels is 3 is staggered.Spacing a between the adjacent longitudinal rib 1 is 10cm.
