Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis cleaning, and in particular to an ultrasonic descaling process applied in a reverse osmosis process. Background Art

[0002] The principle of reverse osmosis technology is to separate these substances from water under the action of a higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, etc. in the water. However, conventional reverse osmosis will produce sediments after operation. After a long time, the sediments accumulate and cause serious scaling that cannot be removed.

[0003] The commonly used treatment method is to remove the reverse osmosis filter and replace or clean it, but this method will cause the entire treatment process to be suspended, reducing the water output efficiency of the reverse osmosis process. Summary of the invention

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0040] Reference Figure 1-Figure 7 , which is an embodiment of the present invention, provides an ultrasonic descaling process applied to a reverse osmosis process. The process uses an ultrasonic descaling system, including: a liquid inlet module 100, a conversion module 200 and a reverse osmosis module 300. The process includes the following steps:

[0041] Step 1: The raw water to be treated is introduced from the liquid inlet pipe 101 into the diversion pipe 102. In the first treatment stage, the raw water only enters the inner side of the sealing sleeve 203 through the second guide pipe 205, and then passes through the Z-shaped channel 208a to be guided into the second connecting pipe 207, and finally flows through the second reverse osmosis filter 302 for reverse osmosis treatment. The ultrasonic transducer 306 located on the same side of the second reverse osmosis filter 302 works, so that the raw water entering the second reverse osmosis filter 302 maintains a turbulent state of water.

[0042] Step 2: The regulating shaft 202 is driven to rotate by the reduction motor 201, and then the regulating shaft 202 drives the sealing shaft 208 to rotate 180 degrees. At this time, the second guide pipe 205 is in a blocked state, and the raw water can only enter the Z-shaped channel 208a through the first guide pipe 204, and then be guided into the first connecting pipe 206, and finally flow through the first reverse osmosis filter 301 for reverse osmosis treatment. The ultrasonic transducer 306 located on the same side of the first reverse osmosis filter 301 works, so that the raw water entering the first reverse osmosis filter 301 maintains a turbulent state of water, making it difficult for sediments to adhere to the surface of the equipment, thereby reducing the scaling tendency of the system.

[0043] Step 3: When the equipment needs to be descaled and cleaned, based on the rotation angle of the sealing shaft 208 in step 2, it is rotated 90 degrees again. At this time, the second guide tube 205 and the first guide tube 204 are both blocked by the sealing shaft 208, and the inlet ends of the first reverse osmosis filter 301 and the second reverse osmosis filter 302 are connected through the Z-shaped channel 208a.

[0044] Step 4: Close the valves at the purified water outlet and concentrated water outlet of the first reverse osmosis filter 301, open the electromagnetic valve 304, and inject cleaning liquid into the first reverse osmosis filter 301 through the backwash pipe 303. The cleaning liquid circulates in the first reverse osmosis filter 301 and the second reverse osmosis filter 302, and emits ultrasonic waves through the ultrasonic transducer 306 to achieve a better descaling effect.

[0045] The liquid inlet module 100 includes: a liquid inlet pipe 101, a shunt pipe 102 connected to one side of the liquid inlet pipe 101, a return pipe 103 connected to the upper end of the shunt pipe 102, a valve plate 104 is arranged on the inner wall of the corner of the return pipe 103, and the valve plate 104 controls the steering through the valve stem shaft 105, which is the same as the opening and closing working mode of the butterfly valve.

[0046] The conversion module 200 includes: a first flow guide pipe 204 and a second flow guide pipe 205 connected to the shunt pipe 102, and a first connecting pipe 206 and a second connecting pipe 207 which are coaxial with the first flow guide pipe 204 and the second flow guide pipe 205, respectively; a connecting block 214 is fixedly connected to one end of the second flow guide pipe 205 and the first connecting pipe 206, and the first flow guide pipe 204 and the second connecting pipe 207 which are close to each other; a sealing sleeve 203 is connected between the connecting blocks 214 on both sides; a rotating connecting block 214 is fixedly connected to the sealing sleeve 203 ... A sealing shaft 208 is connected, and a Z-shaped channel 208a is opened on the sealing shaft 208. The Z-shaped channel 208a changes the flow path of the raw water at different rotation angles. The sealing shaft 208 and the sealing sleeve 203 maintain a tightly fitting and sealed state, and the water flow can only flow axially along the Z-shaped channel 208a. An indicator disk 209 is fixedly connected to the upper end of the sealing shaft 208, and a pointer 209a is set on the indicator disk 209. The turning state of the internal sealing shaft 208 can be intuitively judged by the pointer 209a.

[0047] The conversion module 200 also includes: a transmission shaft 210 fixedly arranged at the upper end of the indicator disk 209, a driving wheel 211 arranged on the transmission shaft 210, a driven wheel 213 arranged on the valve stem shaft 105, and a transmission belt 212 arranged between the driving wheel 211 and the driven wheel 213, so that the valve plate 104 and the sealing shaft 208 rotate synchronously. In the initial state (the state in step one), the valve plate 104 is closed, and it is fully open when rotated 90 degrees.

[0048] The reverse osmosis module 300 includes: a first reverse osmosis filter 301 and a second reverse osmosis filter 302 respectively connected to the first connecting pipe 206 and the second connecting pipe 207, and an installation substrate 305 arranged on the inlet pipes of the first reverse osmosis filter 301 and the second reverse osmosis filter 302, and ultrasonic transducers 306 are arranged on the upper and lower sides of the installation substrate 305, and the ultrasonic transducer 306 extends to the inside of the inlet pipe. The purified water outlet pipe on one side of the first reverse osmosis filter 301 is provided with a backwashing pipe 303, and an electromagnetic valve 304 is arranged on the backwashing pipe 303, and the backwashing pipe 303 regularly transports cleaning liquid through the pump body. When the second guide pipe 205 and the first guide pipe 204 are both closed, the electromagnetic valve 304 is opened so that the first reverse osmosis filter 301 and the second reverse osmosis filter 302 can enter the self-cleaning mode.

[0049] Specifically, when the raw water passes through the second guide pipe 205-Z-shaped channel 208a-second connecting pipe 207 loop and the first guide pipe 204-Z-shaped channel 208a-first connecting pipe 206 loop in sequence, the valve plate 104 is in a closed state. When the cleaning liquid passes through the first reverse osmosis filter 301-Z-shaped channel 208a-second reverse osmosis filter 302 loop, the valve plate 104 is in an open state, so that the raw water can be directly circulated back.

[0050] During use, the present invention controls the working mode of the sealing shaft 208 through the reduction motor 201, so that the raw water can enter the reverse osmosis module 300 through different loops for reverse osmosis purification, that is, when the first reverse osmosis filter 301 is in working condition, the second reverse osmosis filter 302 can be maintained and replaced. Similarly, when the second reverse osmosis filter 302 is in working condition, the first reverse osmosis filter 301 can be maintained and replaced without suspending the process, thereby ensuring the water output efficiency of the process. By allowing the raw water to be in a self-circulating state of the liquid inlet pipe 101, the shunt pipe 102, and the reflux pipe 103, the cleaning liquid can pass through the first reverse osmosis filter 301 and the second reverse osmosis filter 302 for backwashing cleaning, and cooperate with the work of the ultrasonic transducer 306 to achieve a good ultrasonic cleaning effect. When the first reverse osmosis filter 301 and the second reverse osmosis filter 302 are performing reverse osmosis work, the ultrasonic transducer 306 on the same side also remains in working condition, so that the raw water entering the filter maintains a turbulent state of water, so that sediments are not easily attached to the surface of the equipment, thereby reducing the scaling tendency of the system.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
