Description

A kind of parallel channels film and its membrane module

Technical field

The utility model relates to water-treatment technology fields, more specifically, be related to it is a kind of for liquid separation it is parallel Press mold and its membrane module outside channel.

Background technique

Sewage treatment is carried out using membrane technology, especially hollow-fibre membrane or plate membrane technology, is current sewage treatment neck The core technology in domain, and the technology being most widely used.For flow channel for liquids, runner generally cylindrical in shape do not have dead angle and Flow resistance is smaller, and for the runner of other opposite cross sections, liquid flowing is more smooth.Press mold is main outside common cylindrical shaped runner Form is the outer press mold of doughnut, has been widely used in the fields such as environmental protection and water process at present.

In recent years with the integrated development of membrane technology and other technologies, hollow-fibre membrane product is proposed many new It is required that.Many fields as associated in membrane technology and biotechnology, for the efficiency for improving sewage treatment, it usually needs improve activity The concentration of sludge, meanwhile, to meet investment, land occupation and safeguarding simple etc. requirement, and need to shorten entire sewage treatment The process of technique then simplifies the pre-treatment intake to hollow-fibre membrane.Then, sewage with suspended active sludge is into film It is easy to form deposition between film wire during filtering, film wire is caused to pollute severe.Although plate membrane is in anti-high sludge It is more advantageous than hollow-fibre membrane in terms of concentration, but its filling area is smaller, integrated equipment size of the same area is big, maintenance at This height.

Utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, is provided a kind of parallel Channel membrane and its membrane module.

The utility model parallel channels film, is achieved by following technical proposals, and a plurality of cylindrical channel is along same flat Face is arranged in parallel, and separating layer outer wall is wrapped up outside above-mentioned a plurality of cylindrical channel.

The a plurality of cylindrical channel number is 4-10 item.

The cross-sectional circumference side of the parallel channels film is made of straight line or the mellow and full company by having periodical concaveconvex structure Continuousization curve is constituted.

The utility model parallel channels membrane module, is achieved by following technical proposals, and a plurality of parallel channels film is along it Runner direction is arranged in parallel, and also keeping parallelism arranges between each plane of parallel channels film arrangement, a plurality of parallel channels film peripheral hardware Shell is set, shell both ends are poured.

A plurality of parallel channels film number is 6-12 item.

Compared with prior art, the utility model has the beneficial effects that

Compared with existing doughnut membrane technology, film product described in the utility model can effectively avoid the deposition between film wire Problem, to improve the antifouling property of film product；Compared with existing plate membrane technology, film product tool described in the utility model There is higher packed density, to assign equipment higher processing capacity.

Specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.

Parallel channels film is as shown in Figs. 1-2, and a plurality of cylindrical channel is arranged in parallel along same plane, above-mentioned a plurality of cylinder Separating layer outer wall is wrapped up outside channel.The a plurality of cylindrical channel number is 4-10 item.The cross-sectional circumference of the parallel channels film While being made of straight line (see Fig. 1) or by having the mellow and full serialization curve of periodical concaveconvex structure to constitute (see Fig. 2).

The parallel channels film is crowded with common solution (or melt) runner exit by managing with parallel core liquid (gas) Out prepared by die orifice.The solution or melt can be the solution-polymerized SBR or melt spinning film forming feed liquid of different formulations.Fluid squeezes Using cooling or coagulating bath etc. are solidified, pore-forming obtains after out.

Parallel channels membrane module is as shown in figure 3, a plurality of parallel channels film is arranged in parallel along its runner direction, parallel channels film Also keeping parallelism arranges between each plane of arrangement, shell is arranged outside a plurality of parallel channels film, shell both ends are poured.It is a plurality of Parallel channels film number is 6-12 item.

The membrane module its water inlet, produce water and concentrated water direction should all be parallel with press mold outside parallel channels.

The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.
