Abstract
The utility model relates to a recoil type tubular membrane which comprises an external non-woven fabric support layer, an internal non-woven fabric compact layer and a polymeric membrane separating layer I from outside to inside. The recoil type tubular membrane is characterized in that a polyester reinforcing layer is arranged between the external non-woven fabric support layer and the internal non-woven fabric compact layer, and a polymeric membrane separating layer II is arranged outside the external non-woven fabric support layer. The recoil type tubular membrane has the advantages that micro particles and micro-molecular substances blocked in micropores in the tube wall in a membrane support layer can be effectively removed, and the regenerating effect is improved and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of tubular membrane, relates in particular to a kind of backpulsing tubular membrane, is applicable to the processing of sewage.
Background technology
Traditional diffusion barrier has flat sheet membrane, rolled film, tubular membrane and hollow-fibre membrane etc., and flat sheet membrane elementary membrane area is less relatively, and filter efficiency is relatively poor; Rolled film and hollow-fibre membrane easily stop up and easy cleaning not, and therefore higher to the water quality requirement of water inlet, it is higher to be not suitable for handling viscosity, the sewage that solids content is higher.The tubular membrane of cross-flow form can overcome above-mentioned deficiency, it has the filter efficiency height, not susceptible to plugging advantage, but present organic tubular membrane comprises outer nonwoven supporting layer from outside to inside, interior nonwoven compacted zone and polymeric membrane separating layer, when filtering in the sewage inlet pipe formula film, fouling product is trapped within the tube wall then, water after the filtration is come out by the micropore permeation on the tube wall, after a period of time is used in every for this reason filtration, just need to clean attached to the fouling product on the tube wall, existing cleaning method is exactly that water or medicament wash away simply, and for the microparticle and the small-molecule substance that are blocked in the film supporting layer inner tubal wall micropore, it removes effect is not very desirable just.Backwash effect can be fine, but owing to be that single face is filmed, apply back-pressure, and film can be easy to come off, and makes the regeneration effect of tubular membrane and service life reduce thus.
Summary of the invention
At above-mentioned shortcoming, the purpose of the utility model technology is to provide a kind of can effectively remove microparticle and the small-molecule substance that is blocked in the film supporting layer inner tubal wall micropore, improves the regeneration effect and the backpulsing tubular membrane in service life.
Technology contents of the present utility model is, a kind of backpulsing tubular membrane, and it comprises outer nonwoven supporting layer, interior nonwoven compacted zone and polymeric membrane separating layer I from outside to inside; It is characterized in that being provided with a polyester enhancement layer between the nonwoven supporting layer and interior nonwoven compacted zone outside; The nonwoven supporting layer is provided with one deck polymeric membrane separating layer II outward more outside.
The advantage that the utility model is compared with prior art had is: the utility model is to improve the anti-pressure ability of tubular membrane integral body by setting up a polyester layer between nonwoven supporting layer and the interior nonwoven compacted zone outside with this, the nonwoven supporting layer is provided with one deck polymeric membrane separating layer outward more outside, after making that two-layer polymeric membrane becomes one through the fusion of nonwoven supporting layer, film can not produce obscission, the clear water or the medicament of scavenge pipe formula film are washed in the export-oriented tube wall of tube wall, can will be blocked in film supporting layer hole inwall and rinse out easily thus attached to materials such as the lip-deep granules of film, thereby with tubular membrane clean cleaner, the regeneration effect and the service life of having improved tubular membrane.
