A single tree-type membrane consists of top and bottom ends, and external-pressure hollow fibre membrane between both ends. Multiple membrane are parallelly connected via water collecting tube to form a tree-type membrane frame. Multiple air distributing pipes are parallelly connected to form an air distributing pipe frame. Both frames are alternatively arranged. Its advantages are high water output, high strength and high resistance to pollution.

The specific embodiment
As shown in Figure 1 and Figure 2, list of the present invention props up the structure that membrane module constitutes does not have tubular quill housing, and it comprises upper end 2, bottom 3, external pressure hollow-fibre membrane 1.Such membrane module is suitable under water the use.The hollow-fibre membrane perforate at wherein upper and lower casting end place can be drawn filtered solution.As shown in the figure, the casting end housing can be circular or square.The doughnut membrane material can be known hollow-fibre membranes such as Kynoar, polyethylene, polypropylene, polyether sulfone.Adopt casting resins such as known epoxy resin, polyurethane to carry out the end-blocking casting, re-using flexible resins such as silicon rubber, polyurethane carries out second casting to the hollow-fibre membrane root, can effectively solve the problem of membrane fiber root fracture, satisfies instructions for use.And flexible resin casting end face is flushed with the cast envelope body, thereby can prevent deposition in use.
As shown in Figure 2, when the end enclosure of each strain formula membrane module was circular, diameter was 1～8cm; When end enclosure is square, be of a size of 1 * 1cm～8 * 8cm.End enclosure is connected with collector pipe 5 on every row's framework by loose joint or plug-in type hermetically-sealed construction, and above-mentioned collector pipe 5 plays the effect of drawing filtered solution as the filtered solution fairlead.Fig. 2 demonstrates by articulation and carries out ways of connecting: a termination of the end housing of the bottom 2 of membrane module and articulation 3 bonds, and another termination of articulation 3 is through reducer coupling parts 9 and collector pipe 5 bondings that are arranged on the framework.
As shown in Figure 3, many strain formula membrane modules constitute a row, form strain formula film framework.The upper and lower port of every membrane module all is connected with collector pipe 5, thereby constitutes the structure of many strain formula membrane modules parallel connection.5～40 the strain formula films of arranging in every row's strain formula film framework.
A plurality of air distributions carry out parallel connection by gas distribution pipe 6, constitute the air distribution framework.As shown in Figure 4, in the bottom of every emptying gas distributing pipe place framework, evenly arrange 5～40 sudden and violent gas ports 7.
Shown in Fig. 5,6, strain formula film framework and air distribution framework are alternately arranged, thereby constitute membrane module unit.
In addition, as shown in Figure 7, strain formula film on many rows strain formula film framework of strain formula membrane module unit and sudden and violent gas port intersect evenly distribution, that is to say, on the gas distribution pipe framework of correspondence sudden and violent gas port 7 should be set between per two strain formula films 1 on the strain formula film framework, on the strain formula film framework of per two sudden and violent gas port 7 correspondences strain formula film 1 should be set on the gas distribution pipe framework.It can also be seen that from accompanying drawing each two ends of arranging strain formula film framework is connected on total collector pipe 5 ', thereby carries out parallel connection, above-mentioned total collector pipe 5 ' is used to draw filtered solution as the filtered solution fairlead; The two ends of each emptying gas distributing pipe framework are connected on total gas distribution pipe 6 ', thereby carry out parallel connection.
In addition, for operational facility, as shown in Figure 5, every row's strain formula film framework can be extracted out from strain formula membrane module unit by guide rail, is easy to change and checks strain formula film.
