Background technique

MBR membrane reactor is a kind of advanced sewage disposal technology, has land occupation few, treatment effeciency is high, stable etc. Advantage becomes the focus of attention of researchers at present.There are many kinds of forms, including board-like, tubular type, spiral for the membrane module of MBR film Tubular type, board-like curtain, doughnut curtain etc. are most widely used wherein belonging to doughnut curtain.It is used in the industry at present MBR membrane support, need to set up the aeration tube for aeration, and the outlet pipe etc. for outflow of supplying water, therefore whole equipment is heavy Complexity causes cost to increase substantially using a large amount of stainless steel material.And MBR curtain membrane reactor in the prior art, Aeration tube is generally being arranged below diaphragm, and aeration quantity is smaller, and in practice, often due to misoperation or clear It washes and causes the serious dirty stifled of film not in time, to influence to be discharged efficiency, need periodically to be cleaned, affect the work of reactor The service life of efficiency and MBR film.

Summary of the invention

The purpose of this utility model is that: a kind of small in size, MBR at low cost, and that MBR film dirt can be delayed stifled is provided Curtain membrane reactor.

In order to achieve the above object, the technical solution adopted in the utility model are as follows: a kind of MBR curtain membrane reactor, the MBR Curtain membrane reactor includes hollow-fibre membrane and concetrated pipe, and collector pipe and aeration tube are provided in concetrated pipe, is arranged on concetrated pipe Have and produce the mouth of a river and air inlet, produce the mouth of a river and collector pipe connection, air inlet and aeration tube connection, the MBR curtain membrane reactor is set It is equipped with upper set pipe and lower concetrated pipe, the hollow-fibre membrane includes more hollow film wires, and the upper end of film wire is arranged in Shang Ji It closes in the collector pipe in pipe, the lower end of film wire is arranged in the collector pipe in lower concetrated pipe, in upper set pipe and lower concetrated pipe Aeration tube is connect with multiple aerators, and the export directions of multiple aerators is towards hollow-fibre membrane direction；Further, upper collection It closes and is respectively provided in pipe and lower concetrated pipe there are two aeration tube, the aerator that two aeration tubes are connected is located at hollow-fibre membrane Two sides, the horizontal space between each aerator is between 5-10cm；Further, be provided on the aerator it is multiple go out Stomata, different location of each venthole towards diaphragm.

The positive advantageous effects of the utility model are: by the way that collector pipe and aeration tube are integrated into concetrated pipe, Equipment volume and weight are reduced, reduces equipment investment cost, and by the way of being aerated simultaneously up and down and using more To aerator to increase air water to the scouring ability of film surface, the pollution of film can be slowed down, the anti-pollution for improving diaphragm blocks up ability, prolongs The cleaning frequency of long diaphragm and the service life of diaphragm increase working efficiency.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model one embodiment.

Fig. 2 is the structural schematic diagram that the utility model one embodiment concetrated pipe and aerator cooperate.

Fig. 3 is the schematic diagram of internal structure of the utility model one embodiment aerator.

Specific embodiment

In order to more fully explain the implementation of the utility model, the embodiment of the utility model presented below, these realities Applying example is only the elaboration to the utility model, does not limit the scope of the utility model.

In the description of the present invention, it should be understood that term " on ", "lower", "horizontal", "inner", "outside" etc. refer to The orientation or positional relationship shown be based on the orientation or positional relationship shown in the drawings, be merely for convenience of description the utility model and Simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation construction And operation, therefore should not be understood as limiting the present invention.

In conjunction with attached drawing to the further details of explanation of the utility model, it is attached in the figure, it is marked as

1. lower concetrated pipe；2. aerator；3. hollow-fibre membrane；4. air inlet；5. producing the mouth of a river；6. upper set pipe； 7. collector pipe；8. aeration tube A；9. aeration tube B；10. film wire；11. venthole.

It is as shown in the figure: a kind of MBR curtain membrane reactor, including the hollow-fibre membrane 3 being arranged on reactor frame and set It manages, is provided with collector pipe 7 and aeration tube 9 in concetrated pipe, be provided on concetrated pipe and produce the mouth of a river 5 and air inlet 4, produce the mouth of a river and catchment Pipe connection, air inlet and aeration tube connection, the utility model is provided with upper set pipe 6 and lower concetrated pipe 1, hollow-fibre membrane include More hollow film wires 10, the upper end of film wire are arranged in the collector pipe in upper set pipe, and the lower end of film wire is arranged in lower set In collector pipe in pipe, as shown in Fig. 2, being provided with aeration tube A in concetrated pipe and aeration tube B, two aeration tubes are respectively connected with more A aerator, the aerator that two aeration tubes are connected is located at the two sides of hollow-fibre membrane, as shown in figure 3, each aeration Multiple ventholes, different location of each venthole towards diaphragm are provided on device.

When the utility model is used, aerator is aerated simultaneously up and down, in such a way that diaphragm both ends are aerated in opposite directions Gas scouring is carried out to diaphragm, and air water blows to the different location of diaphragm, effectively enhances the scouring ability to film wire, slow down or Fouling membrane is prevented, the anti-pollution for improving film blocks up ability, extends the cleaning frequency of diaphragm and the service life of diaphragm, increases working efficiency； And by the way that collector pipe and aeration tube to be integrated into concetrated pipe, reduce equipment volume and weight, reduce equipment investment at This.

After the embodiments of the present invention is described in detail, one of ordinary skilled in the art is clearly understood that, Various change and modification can be carried out by not departing under above-mentioned claim and spirit, all according to the technical essence of the utility model Any simple modification, equivalent change and modification to the above embodiments belong to the range of technical solutions of the utility model, And the utility model is also not only restricted to the embodiment of example in specification.
