Abstract
The utility model discloses a reverse osmosis membrane ultrasonic cleaning device which comprises a shell and an ultrasonic reactor, wherein a transverse plate for supporting a membrane element to be cleaned is arranged in the shell; the shell and the transverse plate define two cavities; the upper part of the transverse plate is a cleaning cavity, and the lower part is an ultrasonic generation cavity; the cleaning cavity is provided with a sewage outlet communicated therewith; the ultrasonic reactor is arranged in the ultrasonic generation cavity; the inner wall of the cleaning cavity is covered with a lining layer; the ultrasonic reactor is connected with a transducer at the lower part of the transverse plate through a cable. According to the device disclosed by the utility model, based on the traditional membrane cleaning technology, the membrane is cleaned by an ultrasonic generation device; by adopting a small amount of cleaning liquid medicine to assist in the cleaning work, the cleaning of the reverse osmosis membrane can be performed without in an offline cleaning machine; moreover, the drug dosage is reduced, the cleaning efficiency is improved, and the reverse osmosis membrane suffering particularly serious pollution can be cleaned till normal use.
Description
Technical field
The utility model relates to a kind of washing unit with reverse osmosis membrane, relates in particular to a kind of reverse osmosis membrane ultrasonic cleaning equipment.
Background technology
Reverse osmosis membrane is a high-new membrane separation technique, reverse osmosis membrane aperture is little of nanoscale, mostly be less than 10A, under certain pressure, hydrone can be surperficial by film, and the impurity such as inorganic salts, heavy metal ion, organic matter, colloid, bacterium, virus cannot pass through, thereby reach deimpurity object, but the residual a lot of dirt impurity of meeting on reverse osmosis membrane, at this moment just need to clean reverse osmosis membrane simultaneously.The cleaning method of traditional reverse osmosis membrane is divided into on-line cleaning and off-line cleans 2 kinds.
When following variation appears in counter-infiltration system parameter, will clean reverse osmosis membrane: one section of pressure reduction≤0.2Mpa of intersegmental pressure reduction of system, two sections of pressure reduction≤0.1Mpa; In the situation that system operational parameters is constant, by the aquifer yield of temperature correction system, recover design the more than 85% of aquifer yield; Produce the variation of water desalination rate and be no more than 5%, now need to carry out on-line cleaning.
During on-line cleaning, poor for the specific aim of the reverse osmosis membrane of diverse location.Owing to not being a membrane component conventionally in a putamina, so also there is difference in the pollution condition of these membrane components, when using the cleaning fluid of same concentration to go to clean the film of different contamination, the film overclean that must cause, and some films clean not enough situation, therefore cleaning performance is poor, but also easily forms cross pollution.Now just need to carry out off-line cleaning.
Traditional off-line cleaning method is to be mainly preparation cleaning solution, and is squeezed in off-line cleaning machine putamina and reach the effect cleaning up.But scavenging period is long, use the film that cleaning agent amount is many, cleaning efficiency is poor, some are polluted to fouling especially severe to clean not thorough.
Summary of the invention
Long in order to solve in prior art reverse osmosis membrane scavenging period, use cleaning agent amount many, cleaning efficiency is poor, the film that some are polluted to fouling especially severe cleans halfway technical problem, the utility model provides a kind of reverse osmosis membrane ultrasonic cleaning equipment, this technology is on the basis of conventional film cleaning technique, adopt ultrasonic generator to carry out film cleaning, the a small amount of liquid that cleans of configuration is simultaneously assisted its work, the cleaning of reverse osmosis membrane can be not be used in off-line cleaning machine to be carried out, and reduce the use amount of medicament, improve cleaning efficiency, and can clean to normal use polluting the reverse osmosis membrane of especially severe.
A kind of reverse osmosis membrane ultrasonic cleaning equipment, comprise housing 1 and ultrasound reactor 7, in housing 1, be provided with the transverse slat 3 in order to support membrane component 6 to be cleaned, described housing 1, transverse slat 3 limit two cavitys, the top of transverse slat 3 is that cleaning cavity 9, bottom are ultrasonic wave generation cavity 10, clean cavity 9 and be provided with the sewage draining exit 5 being communicated with it, ultrasound reactor 7 is located in ultrasonic wave generation cavity 10, it is characterized in that, described cavity 9 inwalls of washing are covered by inner liner 2, and ultrasound reactor 7 is connected by cable with the transducer 11 of transverse slat 3 bottoms.
Further, the transducer 11 of described transverse slat 3 bottoms is at least one.
Further, described inner liner 2 is any one of rubber, safety glass, polyurethane.Further, described inner liner 2 thickness are 3 millimeters.
Further, described ultrasound reactor 7 is connected in housing 1 bottom.
Further, described sewage draining exit 5 is near transverse slat 3.
Further, described cleaning cavity 9 is 2:3 with the volumetric ratio of ultrasonic wave generation cavity 10.
By the enforcement of above technical scheme, the utility model can not be used in off-line cleaning machine the cleaning of reverse osmosis membrane to carry out, and reduce the use amount of medicament, improve cleaning efficiency, and can clean to normally using polluting the reverse osmosis membrane of especially severe.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model reverse osmosis membrane ultrasonic cleaning equipment.
Accompanying drawing 2 is the top view of accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is described in detail.
As Fig. 1, shown in Fig. 2, the utility model comprises housing 1 and ultrasound reactor 7, in housing 1, be provided with the transverse slat 3 in order to support membrane component 6 to be cleaned, described housing 1, transverse slat 3 limits two cavitys, the top of transverse slat 3 is for cleaning cavity 9, bottom is ultrasonic wave generation cavity 10, clean cavity 9 and be provided with the sewage draining exit 5 being communicated with it, sewage draining exit 5 is near transverse slat 3, ultrasound reactor 7 is located in ultrasonic wave generation cavity 10 and is connected in housing 1 bottom, described cavity 9 inwalls of washing are covered by inner liner 2, inner liner 2 thickness are 3 millimeters, material is rubber, safety glass, any one of polyurethane, ultrasound reactor 7 is connected by cable with the transducer 11 of transverse slat 3 bottoms.
During use, reverse osmosis membrane is positioned on transverse slat 3 in advance, clean cavity 9 internal memories and be placed with cleaning fluid, supersonic generator 7 is transformed into high frequency electrical signal by power frequency electricity, by cable transfer, to transducer 11, by transducer, has been converted to and has been handed over mechanical oscillation frequently to propagate in cleaning fluid, powerful ultrasonic wave in cleaning fluid with the form of density interphase to reverse osmosis membrane radiation, produce " cavitation " phenomenon, in cleaning fluid, produce " bubble " form, produce fracture phenomena.When " cavitation " reached by the moment of reverse osmosis membrane skin breakage, produce the impulsive force that surpasses 1000 atmospheric pressures far away, cause the dirt in the face, hole, gap of reverse osmosis membrane be dispersed, break and peel off, reverse osmosis membrane is reached and purify clean effect, realize the cleaning fluid of cleaning purpose and discharge by sewage draining exit 5.
The utility model is not limited to the cleaning to reverse osmosis membrane, can be applied to equally the cleaning of other membrane components.
