Description

A kind of fiber nanofilter

[technical field]

This utility model relates to Treatment of Industrial Water technology, particularly relates to a kind of fiber nanofilter。

[background technology]

Acceleration along with China's industrialization, modernization, the water requirement of industrial circle and the waste water water yield of generation are huge, the overall economic efficiency of enterprise is not only produced significant impact by the increase and decrease of its water consumption and organic pollution discharge capacity, and to solving location hydropenia contradiction, improve surface water environment situation and have very important effect, in the process that water processes, filtering technique is an of paramount importance ring。It is the new technique grown up the eighties in 20th century that fiber is used for water treatment filtration process process as filter medium, adopting fibrous material is in view of it has bigger specific surface area and voidage than quartz sand or other substance particles materials as a starting point of filtering material, thus infer, having the filter bed that fibrous material is constituted should have the retaining power bigger than conventional granulates filtering material, the raising to filter clogging effect that improves of retaining power has decisive meaning。

[utility model content]

This utility model is solved the technical problem that to be in that to provide a kind of fiber nanofilter to improve filter effect。

For solving above-mentioned technical problem, this utility model provides a kind of fiber nanofilter, including housing, the fiber filtering being located in housing, it is positioned at the water-distributing device below fiber filtering and is positioned at the distribution device below described water-distributing device, the working chamber holding described fiber filtering and water-distributing device it is provided with in described housing, described fiber filtering is distributed in described working chamber and forms filter bed, voidage on this filter bed cross section in the horizontal direction is evenly distributed, and the voidage on this filter bed vertical section vertically is from top to bottom in gradually decreasing distribution。

Further, described housing is provided with cylindrical shape body, is connected to air pipe and the liquid pipeline at body top and is connected to the bottom conduit bottom body。

Further, the top of described liquid pipeline and air pipe extends in body top through described working chamber, and the end of described liquid pipeline and air pipe was equipped with filter element。

Further, the bottom of described liquid pipeline is provided with contrary water inlet and backwash discharge outlet；Described bottom conduit is provided with contrary backwash water inlet and is just washing discharge outlet。

This utility model fiber nanofilter has the advantage that filtering accuracy is high and holding filth capacity is big, also there is the feature that granule filter material backwash wash degree is high and water consumption is few, the filtering accuracy of particulate filter can be solved by problems such as particle diameter of filter medium are limited, substantially improve filter effect。

[detailed description of the invention]

Referring to shown in Fig. 1, Fig. 2, this utility model provides a kind of fiber nanofilter, including housing 10, the fiber filtering 20 being located in housing 10, is positioned at the water-distributing device 30 below fiber filtering 20 and is positioned at the distribution device 40 below described water-distributing device 30。

Ginseng Fig. 1, described housing 10 is provided with cylindrical shape body 11, is connected to air pipe 12 and the liquid pipeline 13 at body 11 top and is connected to the bottom conduit 14 bottom body 11。Described body 11 offers the peep-hole 17 being distributed along the vertical direction, is provided with support base 18 bottom described body 11, is used for playing a supportive role, and in described body 11, be provided with the working chamber 19 holding described fiber filtering 20 and water-distributing device 30。The bottom of described air pipe 12 is provided with air vent 120, and the top of described air pipe 12 is connected in body 11 top through described working chamber 19。The bottom of described liquid pipeline 13 is provided with contrary water inlet 130 and backwash discharge outlet 131, and the top of described liquid pipeline 13 is connected to body 11 top through described working chamber 19。Described bottom conduit 14 is provided with contrary backwash water inlet 140 and is just washing discharge outlet 141 and outlet 142 and air inlet 143。Wherein, the top of described liquid pipeline 13 and air pipe 12 extends in described working chamber 19, and it was equipped with filter element 132 at its end, as shown in Figure 2, described filter element 132 of crossing is positioned at the surface of described fiber filtering 20, described fiber filtering 20 is from top to bottom uniformly distributed formation filter bed, and fiber filtering 20 is dissymmetrical structure and fractal structure described in this utility model preferred embodiment。Described water-distributing device 30 is positioned at below described fiber filtering 20, and it is loose structure, it is possible to be porous plate or antipriming pipe composition。

It is worth mentioning that, described fiber filtering 20 had both had the advantage that fiber filtering filtering accuracy is high and holding filth capacity is big, there is again the advantage that granule filter material backwash wash degree is high and water consumption is few, this filtrate 20 structure of the close desirable filtrate of the porosity profile of the filter bed formed。The upper voidage of cross section (horizontal direction) at this filter bed is evenly distributed, it is ensured that the concordance of water stream channel size during filtration, and its direct effect is that holding filth capacity is uniform, and current short circuit phenomenon is avoided。Vertical section (vertical direction) porosity profile at this filter bed from top to bottom gradually decreases, voidage is along the big up and small down Gradient distribution of filter bed vertical section, what this structure was advantageous in water solid suspension efficiently separates, namely the granule of filter bed top desorption to be easy in the narrow passage volume filter bed of bottom captured and retain。Just because of the uniqueness that the filter bed of this filtrate 20 composition has, therefore this filter is achieved at a high speed and high-precision filtration。

As can be seen here, fiber nanofilter aquifer yield described in the utility model is big, floor space is little, and simple in construction, substantial amounts of ducts and valve can be saved, the more important thing is, in practice, it reaches more than 95% for the particle diameter particle clearance more than 2 μm, multiple pollutant in water can be removed, such as float 70-98%, Organic substance 50-80% etc., and to well adapting to property of concentration of suspension change in former water, as when rainy season, wet season change of water quality are bigger, water outlet remains to reach demanding party's requirement。Feature due to filter bed structure and filtrate 20 itself, it is possible to realize high efficiency filter when being not added with any flocculant, solves a difficult problem for low temperature, low-cloudy water process well。

The above; it it is only most preferred embodiment of the present utility model; not this utility model is done any pro forma restriction; any those of ordinary skill in the art; without departing under technical solutions of the utility model ambit; technical solutions of the utility model are made many possible variations and modification by the method content utilizing the disclosure above, belong to the scope of claims protection。
