Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As illustrated in fig. 1 and 2, a kind of device alleviating or avoid external tubular ultra-filtration membrane and block, comprise inlet channel 1, film connector 2, membrane module 3, outlet conduit 4, dense waterpipe and measuring cell, the influent side of membrane module 3 is provided with at least one for discharging the sewage draining exit 12 of the foreign material accumulating in membrane module water inlet end, sewage draining exit 12 is positioned at duct bottom, the external pipe of sewage draining exit 12 is provided with sewage draining valve 14, sewage draining exit 12 side is provided with at least one Butterworth Hatch 11, the external pipe of Butterworth Hatch 11 is provided with wash-out valve 13, sewage draining exit 12 caliber is less than the inlet channel diameter of membrane module 3, sewage draining exit 12 is connected with inlet channel 1 by the reducer pipe of gradual change diameter.
External milipore filter process section is generally connected with dense waterpipe with inlet channel 1 by film connector 2, intakes and by the hole wall filtration of fenestra 7, suspended particulate contaminants is trapped in fenestra 7, with large stock flow direction dense water water outlet direction.If containing hair, fiber in stain disease, they self have bridging action, when external tubular ultra-filtration membrane works, hair fiber in fenestra 7 does not enter fenestra 7 or enters the fenestra 7 of this membrane module but stopped by the end face 5 of the fenestra 7 of next group, then can pile up more and more at end face 5.The fenestra 7 stopped by fiber substance is fewer and feweri in the water inlet of water inlet end, and even enter fenestra 7 at the dense water end (W.E.) of membrane module 3, the flow velocity in fenestra 7 is more and more lower, is finally blocked by suspension.
Specific embodiment of the utility model is,
For alleviating or avoiding this situation, before fenestra is blocked, periodic flushing and discharge result in blockage dirt, by arranging sewage draining exit and Butterworth Hatch alleviates or avoids the blocking of external tubular ultra-filtration membrane, for convenience of description, the present invention's influent side describes cleaning and blowdown process, and dense water side also can adopt and arrange sewage draining exit and Butterworth Hatch alleviates or avoids the blocking of external tubular ultra-filtration membrane.
Bottom influent side, arrange a sewage draining exit 12, the sewage draining valve 14 can regularly opened on sewage draining exit 12 goes out emissions, avoids blocking.Near end face 5, be provided with the current scour end face 5 that the Butterworth Hatch 11 ， Cheongju being no less than washes mouth 11, the fiber on end face 5 and dirt can be made to depart from the end face of membrane module, drained by sewage draining exit 12.If Butterworth Hatch 11 distance end face 5 is comparatively far away, a segment pipe can be stretched out strengthen in inside the cleaning to end face 5.
As illustrated in fig. 1 and 2, sewage draining exit 12 can design on putamina 6, also can design in the duct bottom be connected with membrane module 3.The sewage draining exit 12 of the centre on the membrane module 3 below in sewage draining exit 12 in FIG and Fig. 2 is opened bottom putamina 6, the sewage draining exit 12 on the left side of the membrane module 3 below in Fig. 2 opens the duct bottom be connected at membrane module 3, the sewage draining exit 12 of the membrane module 3 below in Fig. 2 is illustrated as two, only indicate that two positions can be selected, can arrange as required.The sewage draining exit 12 on the right of the membrane module 3 below in Fig. 2 is opened bottom membrane module 3 is connected the elbow of 180 degree, is substantially to be the minimum point of this section and dirt is easily drained by sewage draining exit because of this point.
As illustrated in fig. 1 and 2, Butterworth Hatch can design on putamina 6, also can design on the pipeline be connected with membrane module 3.The Butterworth Hatch 11 on the right on the membrane module 3 below in Butterworth Hatch 11 in FIG and Fig. 2 is opened on putamina 6, the Butterworth Hatch 11 on the left side of the membrane module 3 below in Fig. 2 is opened on the pipeline that is connected at membrane module 3, the Butterworth Hatch of the membrane module 3 below in Fig. 2 is illustrated as two, only indicate that two positions can be selected, can arrange as required.
As shown in Figure 2, the Butterworth Hatch 11 of membrane module 3 is above in the connecting pipe of membrane module, distant, stretches out a segment pipe to end face annex to strengthen the effect of cleaning in connecting pipe inside.
As shown in Figure 3, Butterworth Hatch 11 connect after pipeline water flow direction with have an angle in the cross section of Butterworth Hatch 11 position; The projection of Butterworth Hatch 11 connecting pipe water (flow) direction is roughly with a certain tangent to periphery direction in the concentric circles that is together circle center of the cross section center of circle, and cleaning current point to membrane module water inlet end plane, make rinse water can well wash away the end face 5 of membrane module when pipe flow speed is normal.
Butterworth Hatch can be placed on the arbitrarily angled of putamina or pipeline, the water (flow) direction of the good pipe blow-through of effect is the tangential direction of cross-section of pipeline.
Cross section is as shown in Figure 3 the facade of an embodiment of sewage draining exit and Butterworth Hatch, and wherein Butterworth Hatch pipeline water flow creates counterclockwise rotary water current, and this direction only represents the issuable consequence of this embodiment.The object that Butterworth Hatch produces current is washed away end face and end face annex, and current enter in directions such as upper and lower, left and right, formed and be similar to counterclockwise, clockwise rotation or double-cyclone.
When sewage draining valve 14 on wash-out valve 13 on the pipeline of Butterworth Hatch 11 and the pipeline of sewage draining exit 12 is regularly opened, can clean and discharge and accumulate nigh dirt, adopt automatic valve can run according to auto-programming.
Disclosed in the utility model, a kind of device alleviating or avoid external tubular ultra-filtration membrane and block, compared with prior art, only increases a small amount of pipeline and valve, invests very little; Wash away by waterpower the blocking alleviating tubular membrane with blowdown, compare better effects if with the closed circuit flushing of physics; Control cleaning simply by limited appropriate valve Non-follow control or automatic program, operation is very easy.
Be noted that, the above embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendments made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
