Abstract
The utility model relates to an enhancement support type tubular film, comprising a transition layer and an active separation layer which are closely compounded, wherein the transition layer is tubular and formed by spirally winding the non-woven material belt and the active separation layer is a casting film liquid layer coated on the inner side of the transition layer and the monofilament is weaved and wound on the outer side of the transition layer to form an enhancement support layer and the enhancement support layer is closely joined with the outer side of the transition layer. The advantages of the enhancement support type tubular film are that: high pressure resistance, not-easy tube bursting, wide application area, high filter efficiency, great adjustment of the material liquid speed, effective control of concentration polarization and reduced film pollution.
Description
Technical field
The utility model relates to a kind of diffusion barrier, particularly a kind of enhancing support type tubular membrane.
Background technology
Membrane separation technique is to be to select barrier layer with the pellicle, is mass transfer power with the pressure differential of film both sides, utilizes each component to see through the aperture difference of film, allows in the mixture some component to see through and keeps other components, thereby reach the technology of separating purpose.Therefore, film pressure at both sides difference is big more, and mass transfer power is big more, and the film separative efficiency is high more.Membrane separation technique is owing to have separations, concentrated, purifying and refining function concurrently, and efficient, energy-saving and environmental protection, molecular level filters and filter process is simple, be easy to feature such as control, and is widely used in food, medicine, biology, environmental protection, chemical industry, metallurgy, the energy, oil, water treatment, electronics, field such as bionical.
Existing tubular membrane adopts non-woven material belt spiral to be entwined more, and the gap that the non-woven material belt produced when twining is bonded to by hot sealing process and forms tubular support together, forms tubular membrane at the inboard casting solution that applies of pipe at last.The problem that this technology exists is: hot sealing process makes that the bonded part is difficult to combine with casting solution on the tubular support, and therefore, when the pressure that separates raise, tubular membrane is easy to generate to be peeled off and damaged, has a strong impact on the normal use of tubular membrane.Patent 200780013091.0 has been introduced a kind of method of high pressure resistant tubular membrane, and the tubular membrane density unevenness is even, shortcomings such as rete is thick, resistance to mass tranfer is big, energy consumption height but this method easily causes.
Summary of the invention
The problem that the technical problems to be solved in the utility model is a cracky under the existing tubular membrane hyperbaric environment, film density is inhomogeneous, rete is thick, resistance to mass tranfer is big, energy consumption is high.For people provide a kind of high pressure resistant, film separation rate height, tubular membrane simple in structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of enhancing support type tubular membrane, comprise the transition zone and the active separating layer that closely are combined with each other, described transition zone is a tubulose, be entwined by non-woven material belt spiral, described active separating layer is the casting film liquid layer that is coated in the transition zone inboard, and the monofilament braiding is wrapped in the transition zone outside and constitutes the enhancing supporting layer, strengthens supporting layer and the transition zone outside and fits tightly.Adopt and twine the enhancing supporting layer that braiding structure forms, can provide uniform support force, reinforced whole tubular membrane structure for transition zone.
Advantage of the present utility model is: owing to adopted outer bracing reinforcement structure, make tubular membrane can withstand voltage height, be difficult for booster, thereby can bear higher pressure and bigger flow of filtrate, therefore widely applicable, filter efficiency is high, bigger flow of filtrate provides bigger face scouring force simultaneously, can effectively control concentration polarization, reduce film and pollute.
Description of drawings
Fig. 1 is the utility model profile.
Fig. 2 is that the utility model strengthens the schematic diagram that supporting layer twines type of weave.
Fig. 3 is the schematic diagram that the utility model non-woven material belt spiral twines form.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 3, tubular membrane is by strengthening supporting layer 1, and transition zone 2 and active separating layer 3 closely are composited.Transition zone 2 is entwined by non-woven material belt spiral, equitant limit was welded together by ultrasonic wave, heat bonding or adhesive when non-woven material belt spiral twined, transition zone 2 can form the single-layer nonwoven layer by single non-woven material belt spiral winding and constitute, and also can twine one or more layers nonwoven layer again in single-layer nonwoven layer outside according to same method and constitute; Strengthen supporting layer 1 by monofilament crocheted or knitting and be wrapped on the transition zone 2 and form, braiding can be finished by braider, and monofilament can be polyester, polyethylene, nylon, carbon fiber, glass fiber and stainless steel wire, and caliber size and length can be decided as required; Utilize the tubular type knifing machine to apply casting solution on transition zone 2 and form active separating layer 3, the material of active separating layer 3 can be polysulfones, polyether sulfone, Kynoar, polytetrafluoroethylene (PTFE) or polyethylene.
