Abstract
The utility model is a nude and vertical beams shaped air blowing type hollow fiber membrane component. The membrane component adopted in prior art for membrane bioreactor is a hangings form which enjoys an advantage of high strength, but shows a shortcoming that the effect fades rapidly. The utility model makes a hollow fiber membrane show nude and vertical beam shape and further form a column shape; the two ends combined of membrane are cap seal heads forming which are based on a resin pouring; the lower ends of the cap seal heads are provided with an air blowing structure respectively to allow a proper volume of air current to float upward along the membrane and further to make the air current in its upward floating wash up and eliminate the pollutants sticking on the membrane surface. The continuously mechanical cleansing manner endows the membranes enjoying a fairly anti-pollution performance with better comprehensive performances. The individual components in the use may realize a serial or parallel connection. Thanks to the merely possession of cap seal heads rather than shell, the utility model has the advantages of easy cleansing, strong anti-pollution ability, large surface area of membrane device, high strength, easy biological fixation, and wide application scope.
Description
Technical field
The utility model is naked vertical Shu Zhuzhuan air-blowing formula hollow fiber film assembly, this membrane module can be used for the bio-reactor of drinking water treatment, sewage disposal, food-drink, bio-pharmaceuticals and cell cultures special use, and can be used for pharmacy industry high viscosity formulation or the various devices relevant with membrane process.
Background technology
Common membrane module is normally made column type with plastics device shell, and this is to rely on the device shell to support and a kind of pattern of protecting as film.Also having a kind of is the cord formula, and its principle is identical with the utility model, and just pattern is a plane formula, and the membrane module of these patterns has two kinds of defectives:
1 has the membrane module of device shell to be mainly used in clean water treatment, be used for then easily making when high viscosity liquids such as biochemical pharmacy and sewage are handled the film surface bonding mutually and cause membrane area to reduce, inter-adhesive being difficult to again of film outer surface cleans simultaneously, finally influence water flux and water treatment effect, more influence the film cleaning performance.
2 cord formula membrane modules are used for than the membrane module that the device shell is arranged having with respect to 1 preferable performance on the membrane bioreactor of immersion, clean molten easy compared with the former, membrane reactor has the adherent of being difficult for characteristics in water treatment procedure, because its film silk is in the aeration tank swing up and down perpendicular to airflow fluctuation, mode can be got rid of the material that sticks to the film surface whereby.But cord formula membrane module shortcoming is the stressed of film and fluctuates perpendicular to the bubble floating direction, the film kind (polyvinylidene difluoride (PVDF) etc.) that this mode is strong to contamination resistance, because of the intensity of its material not as the polypropylene height, rupture at film silk root easily, thereby membrane module lost efficacy prematurely.
Summary of the invention
The purpose of this utility model is the naked vertical Shu Zhuzhuan air-blowing formula hollow fiber film assembly that obtains a kind of simple, efficient, high, no device shell of intensity, has wide range of applications.
A kind of naked vertical Shu Zhuzhuan air-blowing formula hollow fiber film assembly that the utility model proposes, form by tubular fibre, air-blowing formula spiracular plate, resin-cast end socket, protection skeleton, hollow-fibre membrane 4 is that the bundle that hangs down is exposed to be combined into cylindric or the orthogonal membrane module, and an end of membrane module is spiracular plate 3, assembly support 7, resin end socket 1, negative pressure cavity 5 successively; The other end of membrane module is spiracular plate 3, aspiration tube 2, resin end socket 1, negative pressure cavity 5 successively; The negative pressure cavity 5 at two ends all links with negative pressure drinking-water pipe 6.
In the utility model, the diameter of column combined films is 20-300mm, and rectangular aspect ratio is any, film column length scope 0.3-5.0m.
In the utility model, the pore shape of spiracular plate 3 is circular, square, rectangle or trilateral.
In the utility model, hollow-fibre membrane has the protection of film post protective cradle outward.It is netted that support can be as required.
In the utility model, serial or parallel connection uses but the unit membrane assembly can use also separately.
In the utility model when work, be pumped to the negative pressure pipe by negative pressure pump, by the negative pressure pipe negative pressure is transmitted to negative pressure cavity, this moment boundling film forming post hollow-fibre membrane since negative pressure film is treated as a stranger treatment liq infiltrates in the film, thereby intact film forming dialysis filtration procedure.Meanwhile utilize inlet pipe to carry out air-blowing by spiracular plate from bottom to top to intermembrane space, make air-flow the time reach the purpose that purges the film surface contaminant in come-up, spiracular plate is to be convenient to air-blowing and the plate of the multiple hole shape that designs.So structure helps the cleaning after membrane module uses, and improves service efficiency.
The utility model has adopted the tubular fibre mould material of good combination property to make naked vertical Shu Zhuzhuan air-blowing formula membrane module, has improved the over-all properties such as fatigue resistance, antipollution of film greatly.Because this membrane module is to hang down Shu Zhuzhuan's, its stress point and aeration bubble flow direction are parastate, so it is only along with the aeration gas-liquid flow is done the little swing of amplitude, used in addition film obdurability is better, so be difficult for rupturing at the cast root of film and resin end socket.If use the good tubular fibre mould material of antifouling property (as polyvinylidene difluoride (PVDF) etc.), then over-all properties improves manyly, and range of application is wider.
The utility model can be made the exposed type membrane module of arbitrary dimension.Because of having the device shell, its appearance do not fix, so its length is unrestricted.This has very important meaning to improving membrane area and ultrafiltration rate.
The pattern of film device of the present utility model more has a characteristic, be exactly can be, thereby played the effect of bio-reactor, improved the output of sewage disposal and pharmacy industry greatly bacterium or cell fixation outside surface at film, shorten the treatment time of waste water, improved effect and benefit.
