Description
Technical field
The present invention relates to technical field of water treatment equipment, specifically, relate to the novel membrane for water treatment heap of a kind of efficient filtration.
Background technology
Membrane technique is described as the water technology in 21st century, develop over nearly 40 years day by day rapid. Compared with tradition water technology, membrane technique has energy-conservation, less investment, easy and simple to handle, processing efficiency advantages of higher, and its application brings huge environment and economy benefit to the mankind. The range of application of membrane technique in water treatment is very extensive, both can be used for drinking water treatment and also can be used for wastewater treatment, and had also had and set foot in the water treatment of some special industry.
In application of membrane process, especially diaphragm is in the film heap application of layered laminate, because the distance between diaphragm cannot be mated mutually with the cycle rate of pending water in different application environment, usually causes adjacent diaphragms that bonding phenomenon occurs; The membrane for water treatment heap that its diaphragm a kind of as disclosed in patent 201510985976.3 is laterally stacking, if the spacing of its diaphragm arrangement cross little or in applied environment turbulent water excessive, add the permeable adsorption in film face itself, it is easy to the situation occurring that two diaphragms are bonding, so not only reduce the film face area carrying out effective water treatment, reduce water treatment efficiency, but also easily make dirt assemble at bonding film face place, increase the weight of diaphragm pollution level, cause film to be piled and greatly shorten work-ing life. The conventional solution adopted in the industry at present is the installing space increasing diaphragm, ensure the safe spacing of two adjacent diaphragms, although film surface pollution can be reduced to a certain extent, improve work-ing life, but excessive diaphragm spacing turn reduces the water treatment amount of film heap unit volume, the film heap water treatment capacity of same volume reduces, and to be reached equal water treatment level, film heap volume must be increased and increase corresponding production cost, the place that some applied environments are comparatively narrow can't be applicable to, have inconvenience. Therefore, the problem of those skilled in the art's primary study how is become at the water treatment efficiency improving film heap unit volume closely in space as far as possible.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the present invention provides the novel membrane for water treatment of a kind of efficient filtration that can effectively avoid the bonding blocking pollution of diaphragm to pile.
In order to realize above-mentioned purpose, the technical solution used in the present invention is as follows:
The novel membrane for water treatment heap of a kind of efficient filtration, being included in its two ends adopts fixed ring that disc-type diaphragm and the sealing-ring of multiple spaced heap row are connected in series the film reator body being fastened on header, the liquid filtered enters header by the water outlet aperture that in the middle part of it, correspondence is offered on header after disc-type membrane surface filters and collects, and is provided with, between adjacent described disc-type diaphragm, the spacer web being socketed on header; Described spacer web comprises and the mounting ring of header socket, multiple rule arrangement outside mounting ring the inducer that is connected as a single entity with it, and at the water conservancy diversion angle that at least one lateral edge place of each inducer is arranged, wherein, described water conservancy diversion angle is arranged in the pros and cons of inducer at least one lateral edges place, and its gradient is 30 �㡫60 ��.
For the ease of the smooth drainage in film face, described water conservancy diversion angle is the chamfering offered of inducer edge or fillet, and the joining place of described water conservancy diversion angle and inducer is the natural transition of fillet process.
In order to more convenient current guiding function, the corner of described inducer and mounting ring link position is provided with arc-shaped transition portion.
In order to ensure the supportive to diaphragm, the maximum diameter of described inducer is not more than the diameter of described disc-type diaphragm.
More specifically, preferred as one, described inducer is the allotment stay that the ring width of its width and mounting ring is suitable, and its number is 8, centered by the mounting ring center of circle, circumference uniform distribution is outside mounting ring, and is also connected with support ring in annular and concentric with mounting ring in the outermost end of inducer.
As another kind preferably, described inducer is that the width of ring one end to the other end increases gradually and with the fan leaf of a bending amplitude by being connected and installed, and its quantity is that 3-5 is individual, and centered by the mounting ring center of circle, circumference uniform distribution is outside mounting ring. This kind of structure formation also causes inducer to drive mounting ring to rotate in practical application because of the shock action of aeration current, thus is cleared up in film face better, avoids dirt deposition to cause film face to block.
As another kind preferably, described inducer is that its quantity is 4, and centered by the mounting ring center of circle, circumference uniform distribution is outside mounting ring by the straight blade being connected and installed that the width of ring one end to the other end increases gradually and its medullary ray and passing the mounting ring center of circle. Turbulent flow can also be produced at membrane surface, promote the cleaning of diaphragm self.
As another kind preferably, described inducer is the allotment stay that the ring width of its width and mounting ring is suitable, its number is 6, centered by the mounting ring center of circle, circumference uniform distribution is outside mounting ring, and is provided with away from the end, one end of mounting ring with this allotment stay medullary ray symmetrically arranged fork on inducer.
As another kind preferably, described inducer is the allotment stay that the ring width of its width and mounting ring is suitable, its number is 4, centered by the mounting ring center of circle, circumference uniform distribution is outside mounting ring, and arranges two all support rings of concentric and mutual different diameter with mounting ring on inducer along its centerline direction.
As another kind preferably, described inducer is with mounting ring centrosymmetry one to herringbone support portion, and is also provided with for preventing at least one latch rotated inside mounting ring; Described herringbone support portion comprise one through mounting ring center and the main bone portion that is connected with mounting ring, and at least three be symmetrical set in main bone portion divide fulcra portion, wherein dividing the spacing such as is between fulcra portion. It is the situation of upper and lower turbulent water that this kind of structure formation is mainly used in film heap environment for use most cases, it is possible to promote that membrane surface cleans, and extends work-ing life well.
Compared with prior art, the present invention has following useful effect:
The present invention settles the spacer web of different shape adjacent diaphragms to be separated ingeniously between disc-type diaphragm, meet the demand of various application scene, thus water treatment liquid is carried out the drainage between diaphragm, what effectively prevent between two adjacent diaphragms is bonding, the contact area of film face with process water is increased when not increasing film heap overall volume, improve water treatment efficiency and add work-ing life, simultaneously due to the intervention of spacer web structure between two diaphragms, membrane surface is made more easily to produce turbulent flow, greatly reduce the deposition of dirt on film face, and present configuration is simple, applicability is good, it is convenient to manufacture, with low cost, it is with a wide range of applications, it is applicable to applying.
