Description
Technical field
The utility model relates to the reverse osmosis technology field, is specifically related to a kind of filtration that is used for reverse osmosis equipment.
Background technology
Apply in the seawater desalination system along with reverse osmosis technology is increasing; Effect as the filtration of the important parts that catchment of reverse osmosis equipment shows important especially, filtration withstand voltage, prevent impurity and the directly reflection and influence the task performance of reverse osmosis equipment of the size of the ability of catchmenting.Fast development along with water treatment market; Therefore requirement to reverse osmosis equipment task performance, aquifer yield, salt rejection rate constantly promotes, and researches and develops that resistance to pressure is stronger, the central tube of the better effects if of catchmenting, is even more important with the pressure energy power of passing through of lifting means, the filtration that improves equipment effectiveness.
Summary of the invention
The utility model is accomplished in order to solve deficiency of the prior art, and the purpose of the utility model provides that a kind of resistance to pressure is strong, effective filtration catchments.
The technical scheme of the utility model is:
A kind of filtration is characterized in that: comprise be positioned at inner most, its tube wall is provided with several central tubes that run through the aperture of tube wall, be wrapped in the filtration stratum reticulare on the central tube tube wall outer peripheral face and be set in the outer infiltration Membrane cover of said filtration stratum reticulare.
Further, it is hexagonal inner tubal wall that said central tube has cross section, and said inner tubal wall surrounds the tube chamber that can supply fluid to flow through.
Again further, said filtration stratum reticulare is closely twined and forms around central tube tube wall outer peripheral face multilayer by screen pack.
The graticule intersecting angle of said screen pack is 60 °.
Said screen pack is that the polypropylene material hot extrusion molding is arranged.
Further, said hexagon is a regular hexagon.
The filtration of the utility model is improved as the employing hexagonal design with the cross section of the inner tubal wall of central tube by the circle of routine; Through the circumscribed hexagonal mode of interior circle the space in the pipe is increased; Pipe thickness reduces; The water penetration of central tube, the flowability of the intraluminal fluid of enhancing are provided, and the intensity of central tube increases the aquifer yield of raising filter plant; And making the graticule intersecting angle of the mesh that is wrapped in the outer screen pack of central tube through special processes is 60 °; Has the pressure reduction that can reduce before and after filtering; Increase the discharge of filtration; Increase to give water speed, thereby reduce the pressure reduction that causes because of dirty stifled, the fouling of all kinds of materials and obstruction rise the rapidly service life that prolongs filtration and the advantage of cleaning frequency; The infiltration Membrane cover of overcoat can guarantee passing through of hydrone, and stops passing through of impurity, and has impact that opposing comes from the outside, central tube is played the function of protective action.

The specific embodiment
Below in conjunction with the specific embodiment a kind of filtration of the utility model is carried out detailed description.
A kind of filtration of the utility model shown in Fig. 1-3; Comprise and be positioned at inner most central tube 1, be wrapped in the filtration stratum reticulare 3 on central tube tube wall 2 outer peripheral faces and be set in and filter the outer infiltration Membrane cover 4 of stratum reticulare 3; The inner tubal wall of central tube surrounds the tube chamber 5 that can supply fluid to flow through; Tube wall 2 is provided with several apertures that runs through tube wall 6, and aperture 6 is used to make water through getting into tube chamber 5, has the function of catchmenting.
In this example, filter stratum reticulare 3 and closely twine and form around central tube outer wall multilayer by screen pack 7.
In general, the outer hydraulic pressure of filtration is greater than the pipe internal pressure, therefore, catchments and can get in the tube chambers 5 through the aperture on the tube wall 26 through the infiltration Membrane cover mesh 8 that a step passes the screen pack 7 that filters stratum reticulare of going forward side by side again.At needs central tube 1 is washed when cleaning, make pressure in the tube chamber 5 greater than the outer hydraulic pressure of pipe, thereby can the impurity that possibly stop up aperture and mesh be washed away.
In this example; Screen pack is to adopt the polypropylene material hot extrusion molding; The temperature range of control extruder each thermal treatment zone is at 230 ℃-280 ℃, and control extruder extruded velocity is at 30-40rpm, control board hauling speed 6-8 rice/minute; For controlling the flatness after product is extruded, the temperature of control planisher is 70-90 ℃.Plastic cord is reported to the leadship after accomplishing a task after from interior outer mold, extruding, and notes the relative running angle of adjustment machine; The rotation of control machine; Make that two retable material wire vents are 60 degree when joining, thereby obtain the screen pack in this example, pressure difference is 2.39Psi/m before and after it; Pressure difference than the screen pack of existing graticule quadrature 90 degree has reduced by 18.7%, and filter efficiency is better.
In this example, the cross section of the inner tubal wall of central tube is a hexagon.Cross section is that hexagonal inner tubal wall can also suitably be adjusted size and is out of shape slightly; Carry out repeatedly experiment and technology adjustment as required; After the contraction data statistical analysis, can be in the specification of needs with the size Control of the size of the outer tube wall of central tube and inner tubal wall.Further, the cross section of the inner tubal wall of central tube can be regular hexagon.
The utility model is changed the design of conventional circular inner tubal wall; Inner tubal wall is adopted hexagonal design; The space passed through of supplied fluid in the pipe is increased greatly, and hexagonal design can also promote the intensity of central tube under the prerequisite of the thickness that does not increase tube wall, improve its resistance to pressure; Improve the water penetration of central tube, the flowability of the intraluminal fluid of enhancing, thereby improve the aquifer yield of filter plant.Compare with the similar tubing of the circular cylindrical cross-section of routine, under the constant situation of other conditions, can be than the water flow velocity in the raising pipe of limits, the ability of catchmenting improves more than 25%.
Above-mentionedly only several kinds of specific embodiments in the utility model are explained; But can not be as the protection domain of the utility model; Every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think the protection domain that falls into the utility model.
