Description

Technical Field

[0001] This invention relates to the technical field of ultrafiltration membrane water treatment, and in particular to an integrated membrane stack quick-assembly structure and intelligent management method. Background Technology

[0002] Ultrafiltration membrane technology, as one of the core technologies in water treatment, has been widely applied in many key areas due to its precise separation performance. Its core principle is to use pressure as a driving force to separate substances of different particle sizes in a solution using the precise pore size of the membrane, effectively removing suspended solids, colloids, bacteria, viruses, and some large organic molecules. However, traditional ultrafiltration membrane systems have gradually revealed many bottleneck problems in practical applications: First, the system integration is low. Traditional membrane systems use a decentralized, on-site "building block" assembly method, involving the splicing of multiple independent components such as membrane modules, pipelines, and monitoring instruments. This not only results in low installation efficiency and high technical requirements for on-site installers, but also significantly increases the risk of leakage due to complex pipeline connections.

[0003] Secondly, operation and maintenance are cumbersome and costly. The replacement, cleaning and maintenance of membrane modules require professional personnel. Replacement requires shutting down the system and disassembling multiple sets of pipes and electrical connectors, which is time-consuming and labor-intensive, resulting in long system downtime and affecting continuous water supply or production. At the same time, the configuration of a professional maintenance team increases the total life cycle operating cost.

[0004] Third, the level of intelligence is insufficient. The system has weak internal status perception capabilities, and most can only monitor macroscopic parameters such as inlet and outlet pressure. It lacks real-time in-situ monitoring of key parameters such as pressure loss and contamination status within a single membrane stack, making it impossible to achieve predictive maintenance and refined energy consumption management. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated membrane stack quick-assembly structure and intelligent management method.

[0006] To achieve the above objectives, the technical solution provided by this invention is as follows: An integrated membrane stack quick-assembly structure includes a fixed main frame and a detachable smart membrane stack module; The fixed host frame is equipped with an integrated interface socket, a guide and limiting structure, and has a first pipeline network connected to the integrated interface socket. The first pipeline network includes a first power line, a first communication line, and a first fluid pipeline group that are connected to the outside. The detachable intelligent membrane stack module is equipped with an integrated interface plug and a locking mechanism, and has a built-in ultrafiltration membrane structure and a second pipeline network connecting the integrated interface plug and the ultrafiltration membrane structure. The second pipeline network includes a second power line, a second communication line, and a second fluid pipeline group. With the cooperation of the guide and limiting structure and the locking mechanism, the detachable intelligent membrane stack module has its integrated interface plug inserted into the integrated interface socket of the fixed main frame in a blind-plug manner, so as to realize the quick locking connection between the first pipeline network and the second pipeline network.

[0007] In this technical solution, the fixed main frame is integrated with the first power line, the first communication line, and the first fluid pipeline group connected to the outside. The ultrafiltration membrane structure (containing membrane modules) and the second pipeline network used in conjunction with the ultrafiltration membrane structure are integrated in the detachable intelligent membrane stack module. The detachable intelligent membrane stack module can quickly lock and connect all fluid pipelines, power pipelines, communication pipelines, and install the ultrafiltration membrane structure through the use of integrated interface plugs and integrated interface sockets. It can not only be plug-and-play and replace in one step, improving disassembly and assembly efficiency, but also has low technical requirements for on-site disassembly and maintenance personnel. There is no need to worry about complex pipeline connections increasing the risk of leakage. It can significantly shorten system downtime, ensure the continuity of water supply or production process, and reduce operation and maintenance costs.

[0008] Furthermore, the ultrafiltration membrane structure includes a product water chamber, a raw water chamber, and a pipeline connection chamber; The second fluid piping assembly includes a second product water outlet pipe, a second raw water inlet pipe, a second backwash water inlet pipe, and a second concentrate-backwash water outlet pipe; The water production chamber is connected to the integrated interface plug through the second water production outlet pipe and the second backwash water inlet pipe. The raw water chamber is located between the product water chamber and the pipeline connection chamber. The raw water chamber is equipped with a hollow fiber ultrafiltration membrane bundle array. The raw water chamber and the pipeline connection chamber are connected by a through-hole array. The hollow fiber ultrafiltration membrane bundle array and the through-hole array are connected and spaced apart, and one end of each hollow fiber ultrafiltration membrane bundle in the hollow fiber ultrafiltration membrane bundle array is inserted into the product water chamber. The second raw water inlet pipe and the second concentrated water-backwash water outlet pipe are both connected between the integrated interface plug and the pipeline connection cavity.

[0009] In this technical solution, the first fluid pipeline group includes a first water production outlet pipe connected to the second water production outlet pipe, a first raw water inlet pipe connected to the second raw water inlet pipe, a first backwash water inlet pipe connected to the second backwash water inlet pipe, and a first concentrated water-backwash water outlet pipe connected to the second concentrated water-backwash water outlet pipe. The flow path of the raw water is as follows: First raw water inlet pipe → Second raw water inlet pipe → Pipeline connection chamber → (After passing through the through-hole array) Raw water chamber.

[0010] The filtering process is as follows: Under the inlet pressure, some of the water in the raw water passes through the hollow fiber ultrafiltration membrane bundles in the hollow fiber ultrafiltration membrane bundle array (filtration) → enters the inner cavity of the hollow fiber ultrafiltration membrane bundles → and gathers upward to the product water chamber.

[0011] The flow path of the produced water (filtered water) is as follows: Water production chamber → Second water production outlet pipe → First water production outlet pipe → External water production outlet pipe.

[0012] The flow path of the concentrate (the water that cannot pass through the hollow fiber ultrafiltration membrane bundles in the hollow fiber ultrafiltration membrane bundle array) is as follows: Continue flowing within the original water chamber → (after passing through the through-hole array) pipe network connection chamber → second concentrated water-backwash water outlet pipe → first concentrated water-backwash water outlet pipe → external discharge or recovery pipeline.

[0013] The flow path of the backwash water before rinsing is as follows: First backwash water inlet pipe → Second backwash water inlet pipe → Product water chamber → Hollow fiber ultrafiltration membrane bundle inner cavity in hollow fiber ultrafiltration membrane bundle array (entering from the end of the membrane bundle located in the product water chamber) → outer wall of hollow fiber ultrafiltration membrane bundle in hollow fiber ultrafiltration membrane bundle array (located in the raw water chamber) for rinsing.

[0014] The flow path of the backwash water after rinsing is as follows: Continue flowing within the original water chamber → (after passing through the through-hole array) pipe network connection chamber → second concentrated water-backwash water outlet pipe → first concentrated water-backwash water outlet pipe → external discharge or recovery pipeline.

[0015] Furthermore, the guide limiting structure includes a guide rail and a limiting groove; The limiting groove is placed at one end of the guide rail, and its shape is adapted to the shape of the detachable smart membrane stack module. The integrated interface socket is placed within the limiting groove; The detachable intelligent membrane stack module is equipped with a guide groove that matches the guide rail. By having the guide groove and the shape of the detachable intelligent membrane stack module cooperate with the guide rail and the limiting groove of the fixed main frame respectively, the integrated interface plug of the detachable intelligent membrane stack module can be blindly inserted into the integrated interface socket of the fixed main frame.

[0016] Furthermore, the guide rail is provided with a locking groove; The detachable smart membrane stack module has a guide space and a storage space inside; The locking mechanism includes gears, racks, and a locking motor; The gear and the locking motor are installed in the accommodating space, and the gear is connected to the output end of the locking motor and is driven to rotate by the locking motor; The rack is placed in the guide space and meshes with the gear. Driven by the gear, it inserts into or leaves the locking slot along the length of the guide space.

[0017] In this technical solution, the guide rail not only facilitates the blind insertion of the detachable intelligent membrane stack module integrated interface plug into the integrated interface socket of the fixed main frame, but also enables the first pipeline network and the second pipeline network to be quickly locked and connected through its locking groove and locking mechanism.

[0018] Furthermore, the locking mechanism also includes a first permanent magnet and a second permanent magnet that magnetically engages with the first permanent magnet; The first permanent magnet is located at the integrated interface plug; The second permanent magnet is located at the integrated interface socket.

[0019] In this technical solution, the first permanent magnet and the second permanent magnet work together to provide non-contact soft guidance for the detachable intelligent membrane stack module in the initial stage of insertion (i.e., before the integrated interface plug is inserted into the integrated interface socket). It can also provide a flexible locking force for the integrated interface plug that has been inserted into the integrated interface socket. This force works in conjunction with the rigid locking force (the force formed by the gear, rack, locking motor, and locking groove) to achieve a stable and reliable locking effect.

[0020] Furthermore, the top of the detachable smart membrane stack module is provided with a handle and an embedded RFID tag, which serves as a physical backup of the unique identifier (UID) of the detachable smart membrane stack module.

[0021] In this technical solution, the detachable smart membrane stack module is easy to carry with the handle. This allows the unique identification of the detachable smart membrane stack module to be quickly and non-contactly read by a handheld device at any stage of storage, transportation or power outage, which greatly improves the efficiency and accuracy of inventory counting, inbound and outbound management and asset tracking.

[0022] Furthermore, the pipeline connection cavity is equipped with a first pressure sensor, a second pressure sensor, a first pH sensor, a first turbidity sensor, a first vibration sensor, and a second vibration sensor; The water production chamber is equipped with a second pH sensor and a second turbidity sensor. The first pressure sensor, the first pH sensor, the first turbidity sensor, and the first vibration sensor are all installed at the pipe opening at one end of the connection between the second raw water inlet pipe and the pipe network connection cavity; The second pressure sensor and the second vibration sensor are both installed at the pipe opening at the end where the second concentrate-backwash water outlet pipe connects to the pipe network connection cavity. The second pH sensor and the second turbidity sensor are both installed at the pipe opening at the end where the second product water outlet pipe connects to the product water chamber; The detachable smart membrane stack module also has a local MCU and a local memory embedded in it. The local MCU is electrically connected to the first pressure sensor, the second pressure sensor, the first pH sensor, the first turbidity sensor, the first vibration sensor, the second vibration sensor, the second pH sensor, and the second turbidity sensor. The local memory is electrically connected to the local MCU.

[0023] In this technical solution, a first pressure sensor, a second pressure sensor, a first pH sensor, a first turbidity sensor, a first vibration sensor, a second vibration sensor, a second pH sensor, and a second turbidity sensor are integrated into a detachable intelligent membrane stack module. This enables real-time in-situ monitoring of key parameters such as pressure loss and contamination status within the membrane stack, achieving predictive maintenance and refined energy consumption management.

[0024] Furthermore, to achieve the above objectives, the present invention also provides an intelligent management method applied to the aforementioned integrated membrane stack quick-assembly structure, which is managed in conjunction with an external central controller for controlling the first fluid pipeline group. The management process includes: After the detachable smart membrane stack module is inserted and connected to the fixed main frame, the first pipeline network and the second pipeline network are connected. Then, the operating parameters of the detachable smart membrane stack module are collected in real time through the first pressure sensor, the second pressure sensor, the first pH sensor, the first turbidity sensor, the first vibration sensor, the second vibration sensor, the second pH sensor and the second turbidity sensor. The local MCU processes the operating parameters and stores them in the local memory. The local MCU performs real-time local diagnostics based on the processed operating parameters, generates cleaning decisions, contamination type identifiers, and fault warning signals, and reports them to the central controller. If the cleaning decision is "clean immediately", the local MCU also reports the historical cleaning records stored in the local memory to the central controller. The central controller combines the historical cleaning records and contamination type identifiers to control the first fluid pipeline group to perform personalized cleaning of the raw water chamber and its internal hollow fiber ultrafiltration membrane bundle array. After cleaning is completed, the local MCU evaluates the cleaning recovery rate based on the latest operating parameters and updates the health index. Finally, it determines the replacement time of the detachable smart membrane stack module based on the latest health index.

[0025] Furthermore, the cleaning decision is based on the pollution index; If the pollution index is greater than the safety limit, the cleaning decision is "clean immediately"; If the safety limit > pollution index > set threshold, then the cleaning decision is "planned cleaning"; If the pollution index is less than the set threshold, the cleaning decision is "continue monitoring"; The formula for calculating the pollution index is as follows:

[0026] in, This represents the current transmembrane pressure difference, which is the difference between the detection values ​​of the first pressure sensor and the second pressure sensor. This represents the maximum permissible transmembrane pressure difference, which is a preset value; This indicates the rate of increase of the current transmembrane pressure difference; This indicates the maximum permissible rate of increase of the transmembrane pressure differential; This represents the water turbidity gradient, which is the difference between the influent turbidity value detected by the first turbidity sensor at the current moment and the historical baseline value. express Deviation value, which is equal to and The average value; , , The value detected by the first pH sensor. The value detected by the second pH sensor; For pollution weighting coefficients, .

[0027] Furthermore, the health index The calculation formula is as follows:

[0028] in, This is the permeability evaluation value; The product water turbidity score is used. = 100×[ 1 - (current detection value of the second turbidity sensor) [-0.1) / (0.5 - 0.1)], where 0.5 represents the maximum allowable turbidity of the membrane stack, and 0.1 represents the designed turbidity of the membrane stack; For mechanical stability scoring, =100-AB, where A is the vibration deduction for raw water inlet and B is the vibration deduction for concentrated water outlet. A is obtained by comparing the detection value of the first vibration sensor with the safety threshold and the warning threshold; B is obtained by comparing the detection value of the second vibration sensor with the safety threshold and the warning threshold. For health weighting coefficients, .

[0029] Compared with existing technologies, the principles and advantages of this technical solution are as follows: 1. The fixed main frame integrates the first power line, the first communication line, and the first fluid pipeline group connected to the outside. The ultrafiltration membrane structure (containing membrane modules) and the second pipeline network used in conjunction with the ultrafiltration membrane structure are integrated in the detachable intelligent membrane stack module.

There is no need to worry about complex pipeline connections increasing the risk of leakage. It can significantly shorten system downtime, ensure the continuity of water supply or production process, and reduce operation and maintenance costs.

The first and second permanent magnets work together to provide non-contact soft guidance for the detachable intelligent membrane stack module in the initial insertion stage (i.e., before the integrated interface plug is inserted into the integrated interface socket), and can provide a flexible locking force for the integrated interface plug that has been inserted into the integrated interface socket. This, together with the rigid locking force (the force formed by the cooperation of gears, racks, locking motors, and locking slots), achieves a stable and reliable locking effect.

The value detected by the second pH sensor; For pollution weighting coefficients, .

[0060] Specifically, the health index The calculation formula is as follows: in, This is the permeability evaluation value; The product water turbidity score is used. = 100×[ 1 - (current detection value of the second turbidity sensor) [-0.1) / (0.5 - 0.1)], where 0.5 represents the maximum allowable turbidity of the membrane stack, and 0.1 represents the designed turbidity of the membrane stack; For mechanical stability scoring, =100-AB, where A is the vibration deduction for raw water inlet and B is the vibration deduction for concentrated water outlet. A is obtained by comparing the detection value of the first vibration sensor with the safety threshold and the warning threshold; B is obtained by comparing the detection value of the second vibration sensor with the safety threshold and the warning threshold. For health weighting coefficients, .

[0061] In this embodiment, the safety threshold is 1.0 m / s², and the warning threshold is 2.0 m / s². When the detection value of the first vibration sensor 36 is lower than the safety threshold, A is 0; when the detection value of the first vibration sensor 36 is between the safety threshold and the warning threshold, A is 20; when the detection value of the first vibration sensor 36 exceeds the warning threshold, A is 40. When the detection value of the second vibration sensor 37 is lower than the safety threshold, B is 0; when the detection value of the second vibration sensor 37 is between the safety threshold and the warning threshold, B is 20; when the detection value of the second vibration sensor 37 exceeds the warning threshold, B is 40.
