Abstract
The utility model relates to an inner-support capillary filtering membrane, consisting of an inner dense layer, an outer tight layer, a plurality of inner channels and inner supporting structures, wherein, the inner channels are arranged in the capillary and have the same length with the capillary; the supporting structures are arranged between the channels and the inner and outer tight layers. The inner supporting structure and the inner and outer tight layers are made of the same macromolecule material. The integrated capillary membrane is shaped by one time. The inner-support capillary filtering membrane of the utility model can enhance the strength of the capillary membrane in virtue of the inner supporting structure so as to reduce the possibility of breaking or squeezing the capillary. The utility model is especially applicable to a membrane bioreactor.
Description
Technical field
The utility model relates to a kind of interior bearing capillary filtering membrane that has.Described filter membrane comprises NF membrane, milipore filter, micro-filtration membrane; The interior support is meant the supporting construction that forms in the inside of capillary-pipe film, and backing material and filmogen are same material.Interior bearing capillary filtering membrane mechanical strength height is applicable to that all kinds of pressure type membrane filterings and submerged membrane filter, and are specially adapted to membrane bioreactor.
Background technology
Usually realize membrane filtration processes by interior pressure, external-compression type or immersion capillary-pipe film in the known technology.But fracture of wire, flattening or damaging problem appear in simple capillary-pipe film usually owing to mechanical strength is not enough.External-compression type or submerged membrane filter when these capillary-pipe films contact with a large amount of mud, need make the capillary-pipe film shake usually under the impact of air, to lower extracapillary surface contamination problem.This method of operation capillary is fractureed and problem such as breakage even more serious.Useful filament woven mesh thing supports the reinforcement capillary-pipe film preparation method of diffusion barrier in the known technology.This method also because the difference of backing material and filmogen physics and chemical property, makes backing material and filmogen occur separating and causes the film breakage except that the shortcoming of manufacturing process complexity.Therefore, lack a kind of capillary-pipe film in the known technology, especially for the high strength capillary-pipe film of membrane bioreactor with support in the filmogen itself.
The utility model content
The utility model will solve the lower technical problem of capillary-pipe film intensity, and a kind of high strength capillary-pipe film with inner supporting structure is provided.
The interior support capillary-pipe film that the utility model provides is a kind of capillary NF membrane, micro-filtration membrane or milipore filter that forms inner supporting structure with the same material of filmogen of using.The hot strength of capillary-pipe film can be strengthened by the supporting construction of inside, also the possibility that capillary is crushed can be lowered.
The interior support capillary-pipe film that the utility model provides is applicable to that all kinds of pressure type membrane filterings and submerged membrane filter, and are specially adapted to membrane bioreactor.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 support external-compression type capillary filtering face schematic diagram in four kinds of the utility model.
The specific embodiment
Shown in Fig. 1-4, capillary-pipe film of the present utility model is by outer compacted zone (1), internal channel (2), and supporting construction (3) and internal dense lamella (4) four parts are formed.Its China and foreign countries' compacted zone (1) and internal dense lamella (4) are respectively very thin comparatively fine and close column type structures; A plurality of internal channels (2) are to be positioned at the inner and isometric passage of capillary of capillary, are used to collect the liquid through separating layer when external pressure moves, and make it to flow out from end face capillaceous; When moving, interior pressure is used to be filtered the circulation of liquid; Supporting construction (3) is the solid structure between compacted zone outside capillary inside (1) and the internal dense lamella (4), and supporting construction is more loose than outer compacted zone (1) and internal dense lamella (4), can more freely see through liquid.
The outer compacted zone (1) of the utility model interior bearing capillary filtering membrane, internal dense lamella (4) and supporting construction (3) are same macromolecular materials, and the moulding of entire capillary membrane disposable is made.
The cross section of the utility model interior bearing capillary filtering membrane internal channel (2) can be an Any shape, circle as shown in Figure 1 and almost fan shown in Figure 2.
The cross section of the outer compacted zone (1) of the utility model interior bearing capillary filtering membrane can be as Fig. 1-2 and shown in Figure 4 circular or be petal as shown in Figure 3.Petal membrane area shown in Figure 3 is higher.
The internal dense lamella (4) of internal channel was more suitable for as separating layer when the utility model interior bearing capillary filtering membrane moved with inner pressed, and the density of above-mentioned outer compacted zone (1) can be lowered to lower liquid flowing resistance; The density of internal dense lamella (4) has determined the filtering accuracy of this film.Above-mentioned outer compacted zone (1) was more suitable for as separating layer when the utility model interior bearing capillary filtering membrane moved with external pressure or immersion, and the density of internal dense lamella (4) can be lowered to lower liquid flowing resistance; The density of outer compacted zone (1) has determined the filtering accuracy of this film.
In general, the numerical value that needs only internal channel (2) is more than or equal to 2, and the solid structure between the internal channel just can play the effect that the capillary outer wall is supported.But in order to make this supporting role effective on a plurality of directions, the number of internal channel should be more than or equal to 3.The number of internal channel should because the internal channel of excessive number can make the internal channel diameter of this capillary-pipe film too small, be given the liquid mobile resistance that brings therein smaller or equal to 10.If the thickness that increases whole film pipe when internal channel is too much can obviously reduce the gross area of unit volume inner membrance tube outer surface.The quantity of the internal channel shown in Fig. 1-4 is respectively 4,5 and 7.A plurality of internal channels are evenly distributed in capillary inside, are distributed in shown in Fig. 1-2 around the cross section, are distributed in around the cross section again as shown in Figure 3-4 and the center.Take all factors into consideration the gross area factor of internal channel quantity and unit volume inner membrance tube outer surface, the average diameter of internal channel is between 0.3-1.5mm, and the average outer warp of whole film pipe is between 2.5-5.5mm.
