Fiber filter material 2,3 with the stoste that flows into floats in lautertuns 1, forms filtering material layer 4.Solid matter in these filtering material layer 4 absorption stostes.Filtered fluid is fetched into the outside as handling water from the conveying end 11 that is connected with the top board 1b of lautertuns 1.At the middle position of top board 1b, vertically be provided with the polywater spout 5 that prevents fiber filter material 2,3 loss usefulness.Therefore, fiber filter material 2,3 can not be lost to and handle in the water.According to Fig. 5 A, 5B, 5C, polywater spout 5 is described in detail.Fig. 5 A is the stereogram of polywater spout 5.This polywater spout 5 is made cylindric.On the outer circumference surface of polywater spout 5, lay the filter screen 5a that constitutes by wedge wire or punch metal.At the inner face of filter screen 5a uniformly-spaced to fix the muscle 5b that several strengthen usefulness.Imperforate plate is made in the bottom of polywater spout 5, and top is open shape, and flange 5d is fixed on circumferential section.Handle 5c uses when polywater spout 5 is taken out from lautertuns 1.Fig. 5 B is the profile of amplification that the polywater spout 5 of Fig. 5 A is cut off along the X2-X2 line.In this figure, filter screen 5a wedge wire.With slit H side as outer circumference surface, because the interval of this slit H is littler than the minimum thickness L of fiber filter material 2,3, so fiber filter material 2,3 can not run off by slit H.Fig. 5 C is the figure of the installation method of expression polywater spout 5.Insert polywater spout 5 by the ring flange 1c place that is fixed on the top board 1b, flange 5d is placed on the ring flange 1c.1d covers this flange 5d with lid.The circumferential part and the ring flange 1c that will cover 1d with bolt install and fix mutually.
With reference to Fig. 6 A～Fig. 6 D, replace wedge wire to describe to the punch metal 50a～50d that on polywater spout 5, uses.
In Fig. 6 A, punch metal 50a has the circular port 52a that disposes side by side on stainless 51a.The diameter of hole 52a is 1～3mm, than the rugosity (3mm) of the fiber of filtering material 2,3 set little.
In Fig. 6 B, punch metal 50b has circular port 52b and the criss-cross hole 53b that disposes side by side on sheet 51b.Hole 52b, 53b alternate configurations.
In Fig. 6 C, punch metal 50c has the rectangular opening 52c that disposes side by side on sheet 51c.
In Fig. 6 D, punch metal 50d has slotted hole 52d, the 53d that disposes side by side on sheet 51d.Hole 52d, 53d tilt mutually on the contrary.
Below, according to Fig. 7～Figure 13 each operational sequence is described.Fig. 7 is the operation of each machine of expression and the timing diagram of valve opening and closing state.Fig. 8 is the flow chart that operation is filtered in expression.In filtering operation, supply valve V1 and to handle water valve V3 be opening, switching valve V2, abandon water valve V4, draining valve V5 is a closed condition.Bleed valve V6 also closes.Stoste flows into the lautertuns 1 from supply port 6.Filtering material layer 4 makes stoste carry out Separation of Solid and Liquid, and absorption is from the solid matter of stoste.Handle water and take out, be discharged to the outside from handling water valve V3 from conveying end 11.Stop up if mesh can take place for long-time continuous filtration treatment, filtering material, the pressure in the lautertuns 1 rises.Pressure sensor 12 shown in Figure 1 can detect the pressure of this rising.
When pressure reaches the above moment of setting value, filter the operation termination, operation is transferred to the stirring and the washing procedure of filtering material.In addition, also can be used as the moment that the timer that filters continuous time stops to the time that the stirring of filtering material and washing procedure shift.
Below, the stirring and the washing procedure of filtering material described.At first, with reference to Fig. 9, in the filtering material agitating procedure, close supply valve V1, switching valve V2, handle water valve V3, abandon whole valve of water valve V4, draining valve V5.Stop supply pump 10, stop the inflow of stoste and the discharge of processing water.Drive agitating device 7 simultaneously, producing with the vertical axis is the eddy current at center.The speed of gyration of stirring vane 7b is set at 7～11m/sec.With such eddy current agitation and filtration material layer 4, filtering material is flowed.By rotating filtering material with eddy current on one side,, the surface and the inner solid matter that are adsorbed on filtering material are peeled off on one side by impact by current and filtering material collision generation each other.This filtering material agitating procedure is responded the termination of setting timer, is transformed into following filtering material washing procedure.
With reference to Figure 10, in the filtering material washing procedure, open switching valve V2, draining valve V5, close supply valve V1, handle water valve V3, abandon water valve V4.Agitating device 7 continues to be driven.Drive supply pump 10, supply with stostes from the conveying end 11 on the top of lautertuns 1.Stoste becomes the washings that flow downward from conveying end 11.
The washings washing and filtering material that flows downward is discharged with solid matter from the supply port 6 of lautertuns 1 bottom.In the bottom of lautertuns 1, lay filter screen 8.Filter screen 8 can prevent the loss of filtering material.Above-mentioned is to carry out the filtering material explanation in when washing with stoste.But the turbidity height of stoste, when being not suitable for as washings also can use and handle water or other clear water.When utilizing above-mentioned flowing downward to carry out the filtering material washing, preferably the flow velocity with washings is controlled to be 30～50m/hr.When 30m/hr or the flow velocity below the 30m/hr, can make with a little less than the mobile downwards power of the filtering material of eddy current rotation, filtering material can not carry out the rotation of above-below direction, and the regenerated from washing of filtering material is just insufficient.In addition, when 50m/hr or the flow velocity more than the 50m/hr, filtering material will concentrate on the bottom of lautertuns 1.Therefore, washing not exclusively.In addition, increase, become the reason of filtering material damage with respect to the collision number of times of the filtering material of stirring vane 7a.
With reference to Figure 11, when the ratio of the fiber filter material 2,3 of use was great, if stop the supply of stoste, fiber filter material 2,3 was because of the weight sedimentation of the solid matter of absorption.Therefore, suitable from supply port 6 inject washings, from the washing of upwards flowing of conveying end 11 drainings.
In addition, when only using washings, the regenerated from washing of filtering material needs the long time, and incomplete regenerated from washing perhaps takes place sometimes.At this moment, with reference to Figure 12,, make air and washings and usefulness from air jet pipe 9 air supplies.Take this, filtering material and air collide repeatedly, and clean result improves.But, when using air, because the rate of climb of air is fast, so during with the washing that flows downward, air can not be discharged to the outside.Therefore, suitable washing of upwards flowing.This filtering material washing procedure also is transformed into the following water conservancy project preface of abandoning by the termination of setting timer.
With reference to Figure 13, in abandoning the water conservancy project preface, open supply valve V1, abandon water valve V4, close switching valve V2, handle water valve V3, draining valve V5.Stoste or other washings are injected in the lautertuns 1 by supply port 6.Contain remain in the fine fouling product in the lautertuns 1 the washing draining from conveying end 11 drainings.This is abandoned the water conservancy project preface and also is transformed into initial filtration operation by the termination of setting timer or by the nephelometer detection below setting turbidity.
As described above, high-rate fitration machine of the present invention continuously, sequentially filters operation → filtering material agitating procedure → filtering material washing procedure → abandon water conservancy project preface.Thereby, can realize for a long time unmanned running, it is few to keep in repair desired expense, can the various stostes of high speed processing.
With reference to Figure 14, illustrate in the filtering material washing procedure, with respect to the mixing effect of the peripheral speed of stirring vane.
As experimental condition, the diameter of lautertuns is φ 1600mm, highly is 2170mm that capacity is 4.63m
3The filling rate of filtering material is 60%.The power output of the motor of agitating device is 11kW.
Its result, in test 1,4,5, the flow regime of filtering material is good.On the other hand, in test 2, whole filtering materials does not flow.In test 3, the filtering material on lautertuns top does not flow.
As known from the above, preferably the peripheral speed of stirring vane is set at 7～11m/sec.
Because the resistance to compression and the voidage of the fiber filter material that uses in high-rate fitration machine of the present invention are big, can be adjusted into the proportion that is suitable for stoste proterties, processing speed, so can be applicable to the stoste in various fields.For example, untreated water is carried out high-rate fitration and is handled in the time of can be to the rainy day in the convergent current type sewer, perhaps be used in the secondary filter that the height that carries out water for industrial use is handled, perhaps can be used as the water purification in aquarium and swimming pool, bathing pool all aspects such as circulating filtration the filtration treatment device and utilize.
