A kind of spacer web structure for water treatment membrane stack
Technical field
The present invention relates to water treatment facilities technical field, specifically, relate to a kind of spacer web structure for water treatment membrane stack.
Background technology
Membrane technology is described as the water technology of 21 century, over nearly 40 years, develop day by day rapid. Compared with traditional water technology, that membrane technology has is energy-conservation, small investment, easy and simple to handle, treatment effeciency advantages of higher, and its application has brought huge environment and economy benefit to the mankind. Membrane technology being of wide application in water treatment is general, both can be used for drinking water treatment and also can be used for wastewater treatment, aspect the water treatment of some special industry, is also having and is setting foot in.
In application of membrane process, especially diaphragm is in the membrane stack application of layered laminate, because the distance between diaphragm cannot match with the cycle rate of pending water in different application environment, usually causes adjacent diaphragms that bonding phenomenon occurs; A kind of its diaphragm as disclosed in patent 201510985976.3 is stacking water treatment membrane stack laterally, if the spacing of its diaphragm arrangement is too small or in applied environment current disturbance excessive, add the permeable suction-operated of face itself, be easy to occur two situations that diaphragm is bonding, the face area that has so not only reduced to carry out effective water treatment, has reduced water treatment efficiency, but also easily makes dirt assemble at bonding face place, increase the weight of diaphragm pollution level, cause membrane stack greatly to shorten service life. The conventional solution adopting in the industry is at present the installing space that increases diaphragm, ensure the safe spacing of two adjacent diaphragms, although can reduce to a certain extent film surface pollution, improve service life, but excessive diaphragm spacing has reduced again the water treatment amount of membrane stack unit volume, the membrane stack water treatment capacity of same volume reduces, and to reach equal water treatment level, must increase membrane stack volume and increase corresponding production cost, can't be applicable to the place that some applied environments are comparatively narrow, have inconvenience. Therefore, how become the problem of those skilled in the art's primary study at the water treatment efficiency that improves closely membrane stack unit volume in space as far as possible.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of spacer web structure for water treatment membrane stack that can effectively avoid the bonding blocking pollution of diaphragm.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of spacer web structure for water treatment membrane stack, comprise the cover T-Ring for being connected with water treatment membrane stack, multiple flow deflectors that rule is arranged and is connected as a single entity with it outside cover T-Ring, and the water conservancy diversion angle arranging at least one lateral edge place of each flow deflector, wherein, described water conservancy diversion angle is arranged at least one lateral edges place in the positive and negative of flow deflector, and its gradient is 30 °~60 °.
For the ease of the smooth drainage of face, described water conservancy diversion angle is chamfering or the fillet that flow deflector edge offers, and the joining place of described water conservancy diversion angle and flow deflector is the natural transition of fillet processing.
In order to ensure the supportive to diaphragm, the distance on described flow deflector between distance cover T-Ring farthest and cover T-Ring center is not less than 3 times of cover T-Ring radius. And concrete distance is determined according to the diaphragm size on membrane stack in practice.
More specifically, preferred as one, described flow deflector is the allotment stay that its width is suitable with the ring width of cover T-Ring, and its number is 8, centered by the cover T-Ring center of circle, circumference uniform distribution is in cover T-Ring outside, and is also connected with ringwise and the support ring concentric with cover T-Ring in the outermost end of flow deflector.
For more convenient current guiding function, described flow deflector is provided with arc-shaped transition portion with the corner of cover T-Ring link position.
Preferred as another kind, described flow deflector is to be increased gradually and with the fan leaf of a bending amplitude, its quantity is 3-5 by the width of adapter sleeve T-Ring end to end, and centered by overlapping the T-Ring center of circle, circumference uniform distribution is in cover T-Ring outside. This kind of version also drives cover T-Ring to rotate because the percussion of aeration current causes flow deflector in application in practice, thereby better face is cleared up, and avoids dirt deposition to cause face to stop up.
Preferred as another kind, described flow deflector be by the width of adapter sleeve T-Ring end to end increase gradually and its center line through the prismatic blade in the cover T-Ring center of circle, its quantity is 4, to overlap centered by the T-Ring center of circle circumference uniform distribution in cover T-Ring outside. Can also, in membrane surface turbulization, promote the cleaning of diaphragm self.
Preferred as another kind, described flow deflector is the allotment stay that its width is suitable with the ring width of cover T-Ring, its number is 6, centered by the cover T-Ring center of circle, circumference uniform distribution is in cover T-Ring outside, and is provided with symmetrically arranged fork of this allotment stay center line away from the end, one end of cover T-Ring on flow deflector.
Preferred as another kind, described flow deflector is the allotment stay that its width is suitable with the ring width of cover T-Ring, its number is 4, centered by the cover T-Ring center of circle, circumference uniform distribution is in cover T-Ring outside, and on flow deflector along on its centerline direction, arrange two all with the support ring that overlaps the concentric and mutual different-diameter of T-Ring.
Preferred as another kind, described flow deflector is with the cover centrosymmetric a pair of fishbone of T-Ring support portion, and is also provided with in cover T-Ring inner side at least one latch rotating for preventing; Described fishbone support portion comprises a main osseous part being connected through cover T-Ring center and with cover T-Ring, and at least three branch's osseous parts that are symmetrical set on main osseous part, between branch's osseous part, is wherein equidistant. It is the situation of upper and lower current disturbance that this kind of version is mainly used in most cases in membrane stack environment for use, can promote well membrane surface clean, increases the service life.
Compared with prior art, the present invention has following beneficial effect:
The present invention is skillfully constructed, be arranged between the diaphragm on membrane stack by designing the supporting network of various shapes, meet the demand of various application scenarios, thus water treatment liquid is carried out to the drainage between diaphragm, effectively avoid bonding between two adjacent diaphragms, face and the contact area of processing water in the situation that not increasing membrane stack overall volume, are increased, improve water treatment efficiency and increased service life, simultaneously due to the intervention of spacer web structure of the present invention between two diaphragms, make the easier turbulization of membrane surface, greatly reduce the deposition of dirt on face, and the present invention is simple in structure, application is good, be convenient to manufacture, with low cost, be with a wide range of applications, be applicable to applying.
