Description
Technical field
The utility model is related to clean water treatment technical fields, are related to silt, mud, colloid, microorganism, disease in water removal
The reverse-osmosis membrane element of the impurity such as poison, organic matter and inorganic salts, more particularly, to a kind of wound fil-tration membrane module.
Background technology
Currently, coiled reverse osmosis membrane component is made of selvage guide, diaphragm, grid and central tube.Grid is located at reverse osmosis membrane
In the water inlet flow channel constituted between inner surface after piece folding, selvage guide is constituted between being located at the outer surface after reverse osmosis membrane folds
Production water flow passage in, this coiled reverse osmosis membrane component be will produce the end face two sides of water flow passage and far from center water producing pipe one
Side glue bonding makes production water flow passage have the opening towards center water producing pipe, and water purification diaphragm group is in winding center water producing pipe
Afterwards, entire outer surface carries out environmental sealing with outer adhesive tape.The raw water of the rolling reverse osmosis module of this structure from one end flow into
In water flow passage, a part of water is filtered through reverse osmosis membrane to be formed pure water and flows into center water producing pipe along selvage guide, is left unfiltered
Concentrated water is flowed out along grid from the other end of component.For this filtering film component since runner is wide, flow is short, intakes in runner
Speed is slower, and film surface easy tos produce concentration polarization phenomenon, is polluted so as to cause membrane component.The diaphragm of one small pieces pollutes or damage
It is bad, can all salt rejection rate be caused to reduce rapidly, water outlet is unqualified, and membrane lifetime shortens.
Invention content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of wound fil-tration membrane modules.
The utility model is achieved through the following technical solutions：
A kind of wound fil-tration membrane module, including central tube and the clad wound on central tube periphery, the clad packet
Include the grid set gradually, primary diaphragm, selvage guide and secondary diaphragm；An at least adhesive tape is provided on the selvage guide to divide selvage guide
At the region being distributed up and down, setting and the matched through-hole in each region on the central tube.
In the utility model embodiment, flow-limiting valve is installed on the through-hole.
In the utility model embodiment, pressure reducing valve is installed on the through-hole.
In the utility model embodiment, limited valve is installed on the through-hole.
A kind of wound fil-tration membrane module of the utility model, has the advantages that：It is divided into multiple areas on film bag
Domain increases contamination resistance, extends the service life of film.Meanwhile the simple in structure, volume using the composite filter element of the component
It is small, it is easy to accomplish large-scale industrial production.
Description of the drawings
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the enlarged diagram at A in Fig. 1.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in inventive embodiments carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Reference explanation book attached drawing, a kind of wound fil-tration membrane module, including central tube 10 and the packet wound on central tube periphery
Coating, the clad include the grid 21 set gradually, primary diaphragm 22, selvage guide 23 and secondary diaphragm 24；On the selvage guide
It is provided with an at least adhesive tape 25 and selvage guide is divided into the region 26 being distributed up and down, be arranged on the central tube and matched with each region
Through-hole 11.
In one embodiment of the utility model, flow-limiting valve is installed on the through-hole（It is not drawn in figure）.
In one embodiment of the utility model, pressure reducing valve is installed on the through-hole（It is not drawn in figure）.
In one embodiment of the utility model, limited valve is installed on the through-hole（It is not drawn in figure）.
The utility model includes grid, primary diaphragm, selvage guide, secondary diaphragm, central tube, through-hole, through-hole in more detail
Can be inlet opening, metering hole, vent, pressure limiting hole.One layer of selvage guide is pressed from both sides between primary diaphragm and secondary diaphragm constitutes film bag, film
By fluid sealant linear sealing, the 4th side is connected with central tube on three sides around bag, and central tube is equipped with multiple through-holes, the film bag
It being made of several regions not being connected to directly, partition method is to be glued on the inside of film bag along vertical centre pipe tube axial direction,
The adhesive tape for forming several and film bag sides aligned parallel, film bag lattice at along several regions that central tube axis direction arranges.It is described
The part inlet opening of central tube is metering hole, and current-limiting mode is the aperture for reducing inlet opening.The center tube section water inlet
Hole is metering hole, and current-limiting mode is that adjustable flow-limiting valve is installed on hole.The center tube section inlet opening is vent,
It is that pressure reducing valve is installed on hole that it, which subtracts mode,.The center tube section inlet opening is pressure limiting hole, and voltage limiting mode is on hole
Pressure limiting valve is installed.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be new to limit this practicality with this
The interest field of type, therefore equivalent variations made according to the claim of the utility model still belong to the model that the utility model is covered
It encloses.
