Description
Technical field
The present invention relates to water filtration treatment facility, relate in particular to the water filtration treatment facility with filtering material cleaning device.
Background technology
At present; quartz filter be in water treatment the wider filter plant of application, to have outlet effect good; the advantage that floor space is little, if but also ubiquity need regularly to shut down backwash, complicated operation backwash not in time quartz sand harden, the longer outlet effect running time problem such as poorer.Simultaneously, along with the appearance of full-automatic filter, by raw water filtration and two relatively independent processes of carrying out that are integrated into of filtrate cleaning and regeneration simultaneously, but the problem often occurring is: after filtrate cleans, filtrate is reapposed in the process of cylindrical shell, the phenomenon that in the middle of often occurring, filtrate is piled up, is unfavorable for filtrate tiling, cause the filtrate poor fluidity of both sides, thereby reduced the effect that whole system is filtered.
Summary of the invention
The present invention is directed to above problem, provide one to there is filtrate self-cleaning function, effectively prevent the Self-cleaning shifting sand filter that filter course middle part filtrate is piled up.
Technical scheme of the present invention is: comprise that top is the cylindrical cylindrical shell that is taper with bottom, filter is positioned at cylindrical shell middle and lower part, filtering material cleaning device is positioned at cylindrical shell top, and filtrate lifting device connects the silt box of filter and the sand developing tube of filtering material cleaning device; Also comprise filtrate distributor, described filtrate distributor is umbrella, and is positioned at the below of described filtering material cleaning device.
The surface of described filtrate distributor is laid with discharge opening.
It is large that the diameter of described discharge opening becomes from inside to outside gradually.
Described filter comprises the former water water inlet pipe that radial distribution is housed on the ring sparger with raw water inlet that is positioned at filter bottom, former water water inlet pipe is connected to the guiding gutter of the taper water-locator below in cylindrical shell, water-locator top is sand filter course, sand separator and silt box are equipped with in bottom, and downflow weir and clear water output are equipped with in cylindrical shell top.
Described filtering material cleaning device comprises the three phase separator that is positioned at sand developing tube periphery, washed-out sand mud discharging mouth, and sand-washing device is equipped with in sand developing tube bottom.
Described filtrate lifting device comprise connect silt box carry sand pump and the sediment transport pipe that is connected gas on the sand developing tube of top, sand, water inlet.
The operation principle of this filter and process are: the use of Self-cleaning shifting sand filter can be divided into raw water filtration and two relatively independent processes of simultaneously carrying out again of filtrate cleaning and regeneration.The two completes at the diverse location of same filter.
Raw water filtration: when former water is flow automatically by head tank or elevator pump pumps into the ring sparger of filter bottom, through guiding gutter and conical distributor evenly upwards gradually adverse current through filtering layer, impurity in former water is constantly held back, absorption, final filtrate, from the excessive weir flow discharge of filter top, completes filter process.
The cleaning of sand and regeneration: when filtering while constantly carrying out, the impurity in former water is also constantly accumulated and is trapped in filter material surface, and the dirty amount of filter maximum be the sand of bottom.The sand of bottom is carried sand pump and first this part sand is quantitatively submitted in three-phase (water, gas and the sand) separator to top by sediment transport pipe in batches by being located at the compressed air of filter bottom, air venting, water enters in the sand-washing device being connected again and cleans with sand, washed-out sand water is by independent discharge of pipes, the sand of wash clean is scattered again and is distributed to whole filter bed surface, has realized the cleaning of sand and the process circulating.
By the sand of suspended solid pollutant, the passage forming by the sand separator of taper and the inclined plane of filter, arrive down silt box, then be transported in the sand-washing device of top rinse bath by carrying sand pump, sand in lifting process due to air, water, sand is acutely friction under compressed-air actuated effect, the foreign material wash-out that sand is held back, air and sand in three phase separator, water separates, sand is because gravity flows in labyrinth passage by the bottom of sand-washing device, the filtered water on filter bed top is by cleaning water pipe, bottom by decontaminating apparatus enters labyrinth passage, washing water flows from the bottom up in passage, sand slow decreasing, both contact relatively, sand is cleaned.Clean sand is evenly distributed to filter bed central authorities again.Draining after cleaning is discharged by drainage arrangement.Clean displacement can pass through the regulating weir of up-down adjustment drainage arrangement, makes it reach most suitable amount.
The present invention is provided with the filtrate distributor of umbrella below filtering material cleaning device, after filtrate cleans, is scattering into uniformly in filter course by filtrate distributor, avoids the generation of middle packing phenomenon, effectively raises the effect of circulating filtration; On filtrate distributor, offer discharge opening, improved filtrate uniformity; It is large that discharge opening diameter outwards becomes gradually, further promotes uniform effect.The present invention is simple to operate, has improved the efficiency of filtering.
