The specific embodiment
The below will provide for to the device of filtering module accommodating fluid and the detailed description that comprises the filter plant of this device.In context, term " fluid " should broadly be interpreted as being included in the various fluids in the filter plant, the water that purifies such as needs, denitrification gas such as air etc.
Fig. 1 shows the general view of filter plant (being labeled as 1).Described filter plant comprises a plurality of filtering modules (being labeled as 10), generally includes the sand as filtering material.For example, the base cone (bottom cone) partly made by concrete of each filtering module limits.
Described equipment has a plurality of water inlet distributors 20, and treats that the water of denitrogenation enters by it.Each water dispenser 20 has the length that is fit to extend at least two filtering modules.In the embodiment that illustrates, four the parallel water dispensers of above each filtering module, arranging.
Above described water inlet distributor, have the plant air distributor of a plurality of elongated cover 30 forms, it has the length that is fit to extend at least two filtering modules.
In described filter plant 10, each filtering module is provided with the device for continuous wash.Therefore, for each filtering module 10, be provided with the suitable air lift pump 40 that contaminated sand is transported from described base cone.
The cutaway view of described equipment 1 is shown among Fig. 2.The filtering material of sand (this is not shown) form is back taper in each filtering module 10.Described air lift pump 40 is to the bottom of downward-extension near described each filtering module be used to removing contaminated filtering material (being preferably sand).Therefore, filtering module is defined as the filter element that has independently the system that is used for removing contaminated filtering material.
In described graphic embodiment, each water dispenser extends to two filtering modules 10, but can imagine that also they can extend to more than two filtering modules.Each water dispenser 20 is supported on its mid portion by the concrete cone of the pedestal that forms described filter plant 1 and is supported by separately support 22 at its two ends.Equally, each air distributor 30 is supported by separately support 22 at its two ends.Crossbeam 32 is arranged on the center of described air distributor, is used for supporting a plurality of air distributors, equally referring to Fig. 1.
Water is supplied to described water dispenser 20 via water inlet conduit 24 separately, and the while air is supplied to described air distributor 30 via air inlet conduit 34 separately.
Described air distributor 30 has a plurality of hole 30a, can escape through these hole air.Identical height is located in all holes, and this is so that the bubble that the filtering material by the module that comes into question rises can uniform distribution.Preferably, the hole 30a on the both sides of each air distributor replaces the uniform distribution that arranges to reach bubble mutually (mutually displaced).
Explain the running of described filter plant 1 now with reference to Fig. 3.Water by 24 supplies of described water inlet conduit and by described water dispenser 20 uniform distributions in described filtering module.This illustrates by the arrow of " W " expression in Fig. 3.Simultaneously, air by 34 supplies of described air inlet conduit and by described air distributor 30 uniform distributions in described filtering module.This illustrates by the arrow of " A " expression in Fig. 3.Because described water dispenser is arranged on the below of described air distributor, the water that the filtering material by the module that comes into question rises when through described air distributor by the gas inflated there.
Fig. 4 is the detailed end view of described water and air distributor, shows to the water inlet conduit 24 of described water dispenser 20 supply water and air inlet conduit 34 from air to described air distributor 30 that supply.
Fig. 5 is the view that shows the shape of described water dispenser 20 and described air distributor 30.The detailed view of air distributor is shown among Fig. 6, can find out, the hole 30a on the not homonymy of described air distributor replaces mutually.
Another embodiment of filter plant is described now with reference to Fig. 7 and 8.In this embodiment, be provided with a plurality of air distributors 30 that extend to two filtering modules, and described water dispenser 120 is the general type from the form of the arm of described water inlet conduit 124 radiated entends.Thus, in the embodiment such as the front, left the bubble aeration of described air distributor 30 from the water of described water dispenser rising.
Explain another design of described air distributor now with reference to Fig. 9.Each air distributor 130 is comprised of the cover 132 that preferably is made of plastics, but it also can use stainless steel etc.Described cover 132 has ridge and two and is essentially the plane and the inclined plane 132b angled extension of described ridge.On the lower edge of described inclined plane 132b, be provided with a plurality of recess 132c, it is fit to discharge the air that described cover 132 surrounds.By these recesses are set, realized the uniform distribution of air, the size of the bubble of described air distributor 130 is left in the size decision of described recess.
In another embodiment again, described air distributor is the form of Multihole flexible pipe 230, and it is arranged on the top of described water dispenser, referring to Figure 10 and 11.In Figure 10, such air distributor with extend to water dispenser 20 combinations of two filtering modules, and in Figure 11, it and water dispenser 120 combinations from the conventionally form of the arm of described water inlet conduit 124 radiated entends.
Described flexible pipe 230 is preferably made by polyurethane or other suitable plastics, and thus can be according to the layout of described filter plant 1 with different structure arrangements.
Should be appreciated that idea of the present utility model can be used for described water dispenser, and it is not used for described gas distributor.Therefore, the filter plant 1 shown in Figure 12, wherein said water dispenser 20 extends to a plurality of filtering modules 10, but each filtering module has air distributor 330 separately.In this embodiment, each air distributor comprises a plurality of basically straight tubular sections with hole, and wherein, these sections are connected to each other and form a ring.
Preferred embodiment according to filter plant of the present utility model has been described.Should be appreciated that these to change within the scope of the appended claims and do not break away from idea of the present utility model.
