Description
Technical field
The utility model relates to environmental protection water treatment and technical field of membrane separation, and specifically a kind of pulsed tubular membrane is removed contamination facility.
Background technology
Along with the reinforcement of environmental consciousness, membrane separation technique has been widely used in the industries such as food, medicine, chemical industry.
In percolate process, tubular ultra-filtration membrane forms the critical facility in MBR system at present, but because the tubular ultra-filtration membrane that the feature of activated sludge itself is all is all faced with this difficult problem of film blockage, film blockage is mainly because activated sludge causes, in running, fiber fines in sewage sticks in film pipe and causes film bore to diminish after accumulation, and activated sludge is trapped thus cannot arranges outward and causes film blockage.After film blockage, milipore filter area of passage reduces, and system is difficult to normal operation, even causes the collapse of whole percolation liquid treating system.After film blockage, sewage cannot pass through, and cannot realize separation function, thus causes membranous system to be stopped transport.General cleaning method thoroughly cannot dredge the mud of accumulation in film pipe, if use rigid dredging tool likely scratching film pipe, causes membrane component to damage.This situation is avoided to have a kind of fast, effectively and again to the facility of removing contamination that membrane component does not damage.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, solves the technological deficiency existed at present, the utility model discloses a kind of pulsed tubular membrane and to remove contamination facility.
The technical scheme that the utility model adopts is: pulsed tubular membrane is removed contamination facility, comprise liquid storage tank of removing contamination, pulse pump and flexible dredging pipe, described liquid storage tank of removing contamination is connected by pipeline with pulse pump, one end of described flexible dredging pipe is connected with described pulse delivery side of pump, and the other end of described flexible dredging pipe is connected with tubular membrane to be cleaned.
Further, the quantity of described flexible dredging pipe to adapt coupling according to the quantity of described tubular membrane film pipe to be cleaned.
Further, the diameter of described flexible dredging pipe is less than the diameter of described tubular membrane film pipe to be cleaned.
Pulse pump combines with flexible dredging pipe by the utility model, under the effect of pulsating water, is softened the mud blocked in film pipe.Flexible dredging pipe, under the effect of pulse water flow, constantly by the sludge removal in film pipe in advance process, thus realizes dredging film pipe, recovers the object of flux.
The beneficial effects of the utility model are, a kind of pulsed tubular membrane disclosed in the utility model is removed contamination facility, that pulse pump and flexible dredging pipe are combined, by the tamper in the effect dredging film pipe of pulsating water, the pollutant that in film pipe, blocking is real close can be removed fast and effectively, and damage can not be caused to membrane component in the process of removing contamination.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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 shown in Figure 1, pulsed tubular membrane is removed contamination facility, comprise liquid storage tank 1 of removing contamination, pulse pump 2 and flexible dredging pipe 3, liquid storage tank 1 of removing contamination is connected by pipeline with pulse pump 2, one end of flexible dredging pipe 3 is connected with the outlet of pulse pump 2, and the other end of flexible dredging pipe 3 is connected with tubular membrane 4 to be cleaned.
Operation principle of the present utility model is,
Utilize waterpower pulse to change the pressure condition in film pipe (blocking) flow field, and then improve efficiency of removing contamination.
Pulse is exactly suddenly change at short notice, returns rapidly again the physical quantity of its initial value subsequently.
Pulse water pump is utilized to produce waterpower pulse ripple in the utility model, waterpower pulse ripple can set up oscillator field in fluid, film pipe dirt is acted on strong alternating pressure, periodic tensile stress and compression is produced in dirt, shear action is produced to dirt pore media, the cement of Fouling surfaces is come off by vibration, thus removes dirt.For the dirt impurity be jammed in film pipe, under the effect of impulse hunting ripple, the adhesion between impurity and membrane tube wall will wreck under fatigue stress, make it vibrate and come off, and in cleaning process, be discharged film pipe, reach the object removing the blocking of film pipe impurity.
Pulse pump combines with flexible dredging pipe by the utility model, under the effect of pulsating water, is softened the mud blocked in film pipe.Dredging pipe, under the effect of pulse water flow, constantly by the sludge removal in film pipe in advance process, thus realizes dredging film pipe, recovers the object of flux.
A kind of pulsed tubular membrane disclosed in the utility model is removed contamination facility, that pulse pump and flexible dredging pipe are combined, by the tamper in the effect dredging film pipe of pulsating water, the pollutant that in film pipe, blocking is real close can be removed fast and effectively, and damage can not be caused to membrane component in the process of removing contamination.
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.
