Reverse osmosis, also known as reverse osmosis, is a membrane separation operation in which a solvent is separated from a solution using a pressure difference as a driving force. The solution on one side of the membrane is pressurized and when the pressure exceeds the osmotic pressure of the solution, the solvent will reverse osmosis against the natural osmosis direction and the contaminants will mostly be retained in the membrane.

After a period of use, the water yield of the filter membrane gradually decreases due to the blockage of the filter membrane, and the filter membrane must be replaced by a new one to maintain the normal operation of the original filtration system. Therefore, if the replaced reverse osmosis filter membrane can be reused, the use cost can be effectively reduced.

Drawings

Fig. 1 is a schematic structural diagram of a submicron bubble oscillation cleaning system according to an embodiment of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment provides a sub-micron bubble oscillation cleaning system 10. The container 12 is made of stainless steel and contains water. Outside the bottom of the container 12, at least one ultrasonic transducer 22 is mounted and connected to an ultrasonic generator 24.

The commercial specifications of the ultrasonic transducer 22 include two oscillation frequencies: 20kHz and 40kHz, other oscillation frequencies may be used. When a plurality of ultrasonic transducers 22 are mounted, the ultrasonic transducers 22 mounted on the outside of the bottom of the container 12 are connected in series and then connected to an ultrasonic generator 24. In this way, the ultrasonic generator 24 generates ultrasonic oscillations within the vessel 12 and the body of water carried thereby via the ultrasonic transducer 22. If the ultrasonic oscillation amplitude in water is increased, the number of ultrasonic transducers can be increased. The ultrasonic transducer 22 and the ultrasonic generator 24 function to provide acoustic waves to the container 12.

At the bottom of the vessel 12, a microporous plate 32 is placed, which may be made of ceramic membrane microporous material made of ceramic material or rubber plastic material. The micro-well plate 32 has a plurality of micro-wells for providing sub-micron bubbles. Air placed outside the container 12 enters the compressor 34 through the filter screen 33 and is then transferred to the micro-porous plate 32 inside the container 12 through the heat dissipation device 36, so that a plurality of bubbles smaller than 1 micron are generated on the surface of the micro-porous plate 32, the aperture of the micro-pores on the surface of the micro-porous plate 32 is preferably 0.1 micron, and the bubbles generated by the micro-porous plate 32 are also called as submicron bubbles. In general, the appearance size of the micro plate 32 is mainly plate shape, but other tube shapes are also possible. As can be seen, the micro well plate 32, the screen 33, the compressor 34, and the heat sink 36 collectively provide sub-micron bubbles to the container 12. It should be noted that: since the temperature of the compressed air increases, the operation can be continued without the heat radiator 36, but the air temperature increases, and the generated air bubbles are large, while the air bubbles having an effective size of 0.1 μm are relatively small, and the operation is inefficient.

The cleaning operation is started after one or more filters 14 to be cleaned have been mounted above the microplate 32: the filter membrane 14 receives ultrasonic vibrations from the water body, which generates ultrasonic waves from the walls of the vessel 12, and the filter membrane 14 also receives submicron bubbles generated from the micro-porous plate 32.

If the supply of ultrasonic waves is started only singly, part of the pollutants originally adhered to the fiber material of the filter membrane 14 are gradually loosened under the ultrasonic oscillation and finally separated from the filter membrane 14, and the adhered pollutants cannot be continuously peeled off under the ultrasonic oscillation to a certain degree.

In the embodiment, the supply of the submicron bubbles is introduced into the water body, the submicron bubbles are small in size and have static electricity on the surfaces, so that the submicron bubbles are easily adsorbed on solid pollutants on the filter membrane material, when the bubbles are attached to solid matters, the bubbles receive oscillation wave energy transmitted from the water body at intervals, and the received energy is transmitted to the attached solid pollutants just like lever action. The buoyancy of the bubbles themselves, coupled with the ultrasonic vibration, gradually detaches the attached contaminants from the fibrous tissue of the filter membrane 14.

In order to maintain the water quality in the container 12 clean, a pipeline 16 is arranged in the water body at the upper part of the container 12, the water in the container 12 flows out of the container through the pipeline 16, passes through a filter pump 18 and then flows through a filter 20 and then flows back into the container 12, and thus the water quality in the container 12 can be maintained clean to a certain extent after being filtered.

In practice, the effect of removing the filter membrane 14 by singly adopting ultrasonic oscillation or singly adopting submicron bubbles is limited, but the advantages of simultaneously using the ultrasonic oscillation and the submicron bubbles are obvious, so that pollutants on the stripped filter membrane 14 can be effectively removed, the better water yield is recovered, and the use cost of the filter membrane 14 is effectively reduced.

This example is illustrated by the case of cleaning and stripping a reverse osmosis membrane; of course, the submicron bubble oscillation cleaning system and the cleaning method provided in this embodiment may also be applied to other different filter membranes, such as a microfiltration membrane, a nanofiltration membrane, and a butterfly filter membrane.

The sub-micron bubble oscillation cleaning system 10 of the present embodiment is applied to cleaning and stripping contaminants from the filter membrane 14, so that the filter membrane 14 can be recycled. Derivative applications of the system 10 may also be used for heavy metal removal in industrial pollution.

For example, the filter membrane 14 placed in the container 12 is changed into sludge containing heavy metals, and heavy metal compounds are gradually stripped from the sludge under the combined operation of ultrasonic oscillation and submicron bubble adsorption, for example, the sludge is sludge containing metal hydroxide, and acid can be added into the water body to make the water body weak acidic, so that solid heavy metal compounds can form heavy metal ions, and the heavy metal ions are cleaned in the submicron bubble oscillation cleaning system 10 described in this embodiment and collected by the filter 20.

To sum up, submicron bubble oscillation cleaning system 10 is because of ultrasonic oscillation, and submicron bubble's combined action in flourishing water container 12 for impurity in the thing of wasing, for example the heavy metal solid content in impurity and the mud in the various filter membranes can effectively be peeled off by the thing of wasing, makes the filter membrane can cyclic utilization, administer by heavy metal pollution's mud.

Using the above-mentioned sub-micron bubble oscillating cleaning system 10, the present embodiment further provides a sub-micron bubble oscillating cleaning method, including:

the back wash is placed over the microplate.

Wherein the microplate generating sub-micron bubbles comprises:

Further, the cleaning method further comprises:

In summary, the submicron bubble oscillation cleaning system and the cleaning method provided in the present embodiment can effectively separate the contaminants on the object to be cleaned from the object to be cleaned by ultrasonic vibration and attachment and floating of the submicron bubbles, so as to achieve the purpose of cleaning, and are simple to operate and low in equipment cost.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
