Abstract
Description
Technical Field
[0001] This invention relates to the field of production process monitoring technology, specifically to a monitoring and early warning system and method for a water replenishment resin regeneration workshop. Background Technology
[0002] The monitoring and early warning system for the makeup water resin regeneration workshop is an operational assurance mechanism that continuously monitors, uniformly judges, and provides anomaly alerts for key operational states that previously relied on manual experience and on-site observation throughout the entire regeneration process of serial and mixed-bed resins in the makeup water system. Its core lies in the real-time acquisition and comparative analysis of key factors involved in the regeneration process, such as backwash flow rate, regenerator dosing, water level changes, bed pressure, venting status, and resin stratification and expansion status, through sensors, visual monitoring, and control programs. This ensures that each regeneration step remains within the preset safety and process conditions. If abnormal flow rates, insufficient bed filling, abnormal venting, abnormal resin status, or unmet step conditions occur, the system can promptly issue audible and visual alarms and prompt intervention. This allows for early identification of risks that may lead to decreased regeneration efficiency, bed overpressure, or resin escape without continuous manual monitoring, ensuring the safety, consistency, and stability of the resin regeneration process. Meanwhile, by introducing fault prediction and health management mechanisms, the historical trends of sensor signals, execution equipment and process parameters are modeled and analyzed to assess the health status and potential fault risks of equipment in real time, identify abnormal degradation characteristics in advance and provide maintenance warnings, thereby realizing the transformation from post-event alarm to pre-event prevention, and further improving the operational reliability and full life cycle management level of the makeup water resin regeneration workshop.
[0003] The existing technology has the following shortcomings: In existing technologies, during the resin regeneration process in makeup water, after the mixed bed completes backwashing and stratification and enters the settling stage, the stability of the settling state is usually judged solely by observing the clarity of the resin interface through a sight glass, lacking continuous monitoring and assessment methods for the internal state of the bed. During this settling process, factors such as the temperature difference between the upper and lower water bodies within the bed and heat dissipation from the walls can easily create a persistent temperature gradient, causing the effective density of the resin particles to change over time. This leads to a slow reversal of the density distribution and a hidden rearrangement of the particle structure within the resin layer. Because this process is gradual and internal, the resin interface remains stable when observed from the surface, making it difficult to detect abnormalities in a timely manner. After entering the regeneration stage, the regenerated liquid preferentially flows rapidly through the low-resistance channels formed by the structural rearrangement within the bed, failing to uniformly cover and fully contact the resin layer. This results in a short circuit in the regenerated liquid, preventing some resin from being effectively regenerated. Ultimately, this leads to a significant decrease in resin regeneration efficiency or even regeneration failure, increasing operational risks and affecting the stable operation of the water treatment system.
[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0005] The purpose of this invention is to provide a monitoring and early warning system and method for a water replenishment resin regeneration workshop to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a monitoring and early warning method for a water replenishment resin regeneration workshop, comprising the following steps: During the resin regeneration and settling stage of the replenishment water, temperature, pressure, flow rate, and video information at the upper and lower positions of the bed are collected simultaneously. The temperature, pressure, flow rate, and video information are compared and analyzed to generate a settling status linkage record that reflects the heat transfer relationship and water flow change relationship during the settling process. Based on the sedimentation status linkage record, the temperature change trend of the upper and lower positions of the bed is continuously tracked, and the temperature change trend is compared and analyzed with the changes of the resin interface in the screen information to generate rearrangement prompt marks that reflect the internal state changes of the resin. Based on the rearrangement prompts, a low-pressure water flow process is introduced before entering the resin regeneration stage. Water flow reaction information of different areas of the bed is collected during the low-pressure water flow process, and the water flow reaction information is analyzed to generate a flow distribution record reflecting the distribution of abnormal water flow paths. By using flow distribution records, the entry sequence, entry intensity, and entry location of the regenerated liquid are reconfigured to generate a regeneration entry schedule. Based on the regeneration schedule, controlled reverse pressure changes are introduced during resin regeneration to regulate the water flow within the bed.
[0007] Preferably, the steps for generating the settlement status linkage record are as follows: During the static settling stage, temperature, pressure, flow rate, and video information were simultaneously collected at the upper, middle, and lower parts of the bed and recorded according to a unified time reference. Based on the synchronously recorded temperature information, a temperature change sequence along the height of the bed is constructed, and the pressure and flow information are organized according to time correspondence to form basic monitoring data reflecting the internal state of the bed. Based on basic monitoring data, temperature, pressure and flow information are correlated to obtain a multi-dimensional information combination that reflects the relationship between heat transfer and water flow changes. By combining multidimensional information with image information and performing temporal and spatial correspondence analysis, a sedimentation status linkage record covering temperature distribution, water flow changes, and resin interface state is generated.
[0008] Preferably, during the generation of the settling state linkage record, temperature information, pressure information, flow information and image information are continuously and synchronously recorded, so that the settling state linkage record covers the entire static settling stage and maintains a time correspondence according to the height of the bed, so as to reflect the continuous change characteristics of heat transfer relationship and water flow change relationship during static settling.
[0009] Preferably, the steps for generating rearranged hint tags are as follows: After the settling status linkage record is formed, the temperature information in it is processed by time series and a temperature change trend is established according to the height of the bed. Based on the obtained temperature change trend, the video information in the sedimentation state linkage record is sorted out according to time correspondence to construct the resin interface change sequence. Based on the temperature change trend and the resin interface change sequence, a synchronous comparative analysis was conducted to establish the time correlation between temperature change and interface change. Based on the temporal correlation, the temperature change characteristics and resin interface change characteristics are correspondingly identified, and rearrangement prompts with time interval attributes and spatial location attributes are generated.
[0010] Preferably, when forming the rearrangement indication mark, the time change characteristics in the temperature change trend are correlated with the position change characteristics in the resin interface change sequence, so that the rearrangement indication mark simultaneously contains the bed height position information and the time interval information of the static settling stage.
[0011] Preferably, the steps for generating the flow distribution record are as follows: After the rearrangement prompts are generated, the time intervals and spatial locations corresponding to the prompts are organized, and the inlet location, outlet location, and water pressure setpoint for the low-pressure water flow process are determined. Based on the determination of water supply conditions, a low-pressure water supply process is introduced, and the liquid level inside the bed is adjusted so that the water supply process is carried out in a closed water environment. During the low-pressure water flow process, flow rate, pressure and image information are collected simultaneously at different height and radial positions of the bed to form water flow response information; After obtaining the water flow response information, spatial correspondence analysis is performed on the flow rate information, pressure information, and image information to generate a flow distribution record that reflects the distribution of water flow paths inside the bed.
[0012] Preferably, during the low-pressure water flow process, the collected flow and pressure information are divided into zones according to the height of the bed, and the flow change characteristics of each zone are analyzed in correspondence with the local disturbance in the screen information to distinguish the concentrated and dispersed areas of the water flow path, and further refine the spatial distribution characteristics of the water flow path in the flow distribution record.
[0013] Preferably, the steps for generating the regeneration entry schedule are as follows: After the flow distribution record is formed, the flow intensity distribution and pressure gradient distribution in different regions of the record are sorted out to form the regional division of the water flow path inside the bed. Based on the completion of the water flow path area division, the time information in the flow distribution record is integrated to form a time distribution feature that reflects the formation, stabilization and change process of the water flow path; After obtaining the regional and temporal distribution characteristics of the water flow path, the entry sequence, entry intensity, and entry location of the regenerated liquid are configured so that the entry parameters correspond to the water flow path distribution. After configuring the entry parameters, the entry order, entry intensity, and entry location are integrated to generate a regeneration entry schedule.
[0014] Preferably, based on the regeneration entry schedule, the controlled reverse pressure change is introduced during the resin regeneration process to adjust the water flow status within the bed, as follows: After the regeneration entry schedule is formed, the range of reverse pressure changes and the timing of application are determined based on the order, intensity and location of regeneration fluid entry. Based on the completion of the reverse pressure change setting, the reverse pressure change is introduced according to the time sequence of the regeneration entry schedule, so that the water flow direction in the bed changes in stages. During the implementation of reverse pressure changes, the magnitude and duration of the reverse pressure changes are adjusted according to the corresponding stage of the regeneration entry schedule. After completing the reverse pressure change adjustment, the reverse pressure change process is matched with the regeneration entry schedule to form a water flow status adjustment record.
[0015] A monitoring and early warning system for a makeup water resin regeneration workshop includes a sedimentation monitoring module, a status identification module, a flow detection module, a regeneration control module, and a dynamic adjustment module. The sedimentation monitoring module simultaneously collects temperature, pressure, flow rate, and video information at the upper and lower positions of the bed during the resin regeneration and static sedimentation stage of the replenishment water. It also compares and analyzes the temperature, pressure, flow rate, and video information to generate a sedimentation status linkage record that reflects the heat transfer relationship and water flow change relationship during the static sedimentation process. The status recognition module continuously tracks the temperature change trend of the upper and lower positions of the bed based on the sedimentation status linkage record, and compares and analyzes the temperature change trend with the changes of the resin interface in the screen information to generate rearrangement prompt marks that reflect the internal state changes of the resin. The flow detection module introduces a low-pressure water flow process before entering the resin regeneration stage based on the rearrangement prompt mark. It collects water flow reaction information in different areas of the bed during the low-pressure water flow process, analyzes the water flow reaction information, and generates a flow distribution record that reflects the distribution of abnormal water flow paths. The regeneration control module uses flow distribution records to reconfigure the entry sequence, entry intensity, and entry location of the regenerated liquid, generating a regeneration entry schedule. The dynamic adjustment module, based on the regeneration entry schedule, introduces controlled reverse pressure changes during resin regeneration to regulate the water flow within the bed.
[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows: This invention introduces the synchronous acquisition and dynamic analysis of multi-dimensional parameters during the resin regeneration settling stage, enabling continuous sensing and correlation judgment of temperature distribution, water flow changes, and resin interface conditions within the bed. This allows for the creation of a linked record that accurately reflects the evolution of the internal state during settling. This method effectively avoids information lag caused by relying on manual observation, allowing for the early identification of minute changes within the resin layer. It provides data for liquid flow distribution during the regeneration stage, transforming the regeneration process from passive observation to active monitoring, thus improving the controllability and operational safety of the resin regeneration process.
[0017] This invention reconfigures the entry sequence, intensity, and location of the regenerated liquid based on flow distribution records, and introduces controlled reverse pressure changes during the regeneration phase to continuously regulate and equalize the liquid flow path within the bed. This method eliminates short-circuiting of the regenerated liquid caused by local low-resistance channels during regeneration, ensuring full contact between the regenerated liquid and the resin layer, promoting uniform regeneration reaction, thereby improving resin regeneration quality, reducing regenerated liquid consumption, and ensuring the long-term stability of the makeup water system and the consistency of regeneration results.

[0020] Figure 2 This is a schematic diagram of a monitoring and early warning system for a water supply resin regeneration workshop according to the present invention. Detailed Implementation
[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art.
[0022] This invention provides, for example Figure 1 The method for monitoring and early warning in a makeup water resin regeneration workshop, as shown, includes the following steps: During the resin regeneration and settling stage of the replenishment water, temperature, pressure, flow rate, and video information at the upper and lower positions of the bed are collected simultaneously. The temperature, pressure, flow rate, and video information are compared and analyzed to generate a settling status linkage record that reflects the heat transfer relationship and water flow change relationship during the settling process. To accurately grasp the internal operating status of the resin regeneration and settling stage of the makeup water, a settling status linkage record reflecting the heat transfer relationship and water flow change relationship is established through comprehensive collection and correlation analysis of temperature information, pressure information, flow information and video information. The specific implementation steps are as follows: At the start of the settling phase, typical locations at the top, middle, and bottom of the bed structure of the makeup water resin regeneration device were selected as monitoring nodes. Temperature sensing units, pressure sensing units, and flow measurement units were deployed at each node. A visual observation window or image acquisition device was installed outside the bed to simultaneously acquire overall visual information of the water and resin layer inside the bed. The temperature sensing units collected real-time temperature values at each node to reflect the heat distribution characteristics between the upper and lower areas of the bed. The pressure sensing units collected changes in static pressure at each node to reflect the hydraulic pressure difference experienced by the resin layer during settling. The flow measurement units collected information on minute seepage flows or slow flow trends to reveal the movement patterns of residual water during the settling phase. The image acquisition device captured visual changes in the resin layer interface, water turbidity, and local disturbances. All of the above information was recorded synchronously using a unified time reference, ensuring consistency in the correspondence between temperature, pressure, flow, and visual information over time, providing fundamental data support for subsequent joint analysis.
[0023] Based on the acquisition of multi-point synchronous data, temperature information at various locations above and below the bed is processed. Temperature changes at different nodes are arranged in a time series and correlated with the bed's height to create a dynamic data map reflecting the longitudinal temperature distribution. Continuous data acquisition reveals a significant temperature difference between the upper and lower water bodies during the initial settling period, which gradually diminishes over time. Simultaneously, pressure and flow rate information are matched and analyzed. By comparing pressure differences and micro-flow rate trends at different locations at the same time point, the overall static stability of the water within the bed and the presence of localized residual flow are determined. At this point, the temperature change curve, pressure change curve, and flow rate trend constitute the basic monitoring matrix for the settling stage, providing continuous data for further analysis of heat transfer and flow relationship changes.
[0024] After establishing the basic monitoring matrix, temperature, pressure, and flow information are comprehensively correlated and processed. Temperature change is used as the primary indicator of heat transfer; by comparing the rates of temperature change at the top and bottom over a longer time dimension, the trend of heat transfer from bottom to top or from top to bottom is determined. Pressure change is used as a reference for water stability; by analyzing the pressure difference between adjacent locations, the degree of density stratification within the stagnant water body is assessed. Flow change is used as a reference for seepage conditions; by analyzing low-velocity flow trends, potential areas of slow movement are identified. Then, these three types of information are overlaid and analyzed on the same time axis to obtain a multi-dimensional information combination reflecting the direction of heat transfer and the trend of water flow during the stagnant settling stage. This combination clarifies the temporal patterns of temperature gradient formation and dissipation within the bed, as well as the changing trajectory of the internal flow path of the water body during settling, providing continuous state data for judging the stability and uniformity of the resin layer during the stagnant stage.
[0025] After obtaining multi-dimensional information, temperature, pressure, and flow rate information are cross-referenced with visual information. By analyzing the positional changes, clarity, and local light and shadow variations of the resin interface in the visual information, combined with the temperature distribution curves, pressure variation distribution, and flow rate trends at the same time, a correspondence is established, creating a dual temporal and spatial correlation between various information types. This generates a complete settling state linkage record. This settling state linkage record uses time as the main axis and bed height as the reference dimension, covering the interlayer difference in temperature information, the distribution difference in pressure information, the micro-changes in flow rate information, and the interface changes in visual information. Thus, it comprehensively characterizes the heat transfer and water flow changes during the static settling process using multi-source synchronous data. Through continuous recording, it can reflect the diffusion process of heat from high-temperature to low-temperature zones, the evolution of water from dynamic to static, the gradual clarification trend of the resin layer interface, and the dynamic process of internal water flow transforming from uneven to uniform during the static settling process, providing a complete settling state data foundation for the replenishment water resin regeneration stage. Throughout the process, temperature, pressure, flow, and video information remain consistent in both time and space. The sedimentation status is continuously recorded and covered throughout the entire settling stage, ensuring a complete reflection of the internal physical changes during the resin regeneration settling process.
[0026] Based on the sedimentation status linkage record, the temperature change trend of the upper and lower positions of the bed is continuously tracked, and the temperature change trend is compared and analyzed with the changes of the resin interface in the screen information to generate rearrangement prompt marks that reflect the internal state changes of the resin. Based on the sedimentation status linkage record, the internal temperature change trend and resin interface change during the static sedimentation stage of the makeup water resin regeneration are continuously tracked and compared for analysis, thereby generating rearrangement prompts reflecting the internal state changes of the resin. The specific steps are as follows: After the settling state linkage record was completed, the temperature information in the record was processed into a time series. Specifically, the temperature data from each acquisition node in the upper, middle, and lower parts of the bed were arranged according to the sampling time sequence to establish a temperature change trend curve containing both time and spatial dimensions. In this process, the height of the bed was used as the vertical axis, and the sampling time as the horizontal axis, forming a dynamic data sequence reflecting the evolution of temperature changes over time. By continuously tracking the relative differences in temperature changes between the upper and lower parts, the trend of the upper and lower regions gradually becoming more consistent during the static process can be observed, and stages where the rate of temperature change differs can also be captured. The temperature change trend reflects the direction and speed of heat transfer at different heights during the settling stage, laying the foundation for subsequent comparative analysis with video information.
[0027] Based on the obtained temperature change trend curve, the image information from the sedimentation state linkage record was continuously processed frame by frame. Through time synchronization of the image data, the image at each moment was matched with the corresponding temperature information to form a time-consistent image sequence. For each frame, the position, morphology, and light and shadow features of the resin interface were extracted and arranged chronologically to construct a resin interface change sequence. As the settling time progresses, the clarity of the resin interface, the smoothness of the interface lines, and the changes in color distribution above and below the interface can reflect the subtle state adjustment process within the resin layer. By summarizing and processing the continuous image information, the displacement curve and morphological change trend line of the resin interface over time can be obtained, providing visual evidence for the next step of comparative analysis.
[0028] After obtaining the temperature change trend and the resin interface change sequence, a synchronous comparative analysis of the two types of information is performed. The temperature change curve segments at the same time point are correlated with the position and state of the resin interface in the image. By comparing the difference in the rate of temperature change between the upper and lower parts and the directionality of the interface change, the impact of temperature gradient changes on the resin layer structure is identified. When the upper temperature decreases faster than the lower temperature, it indicates that heat is transferred from bottom to top, and the resin layer may slightly increase in density due to cooling of the upper part, thus causing a decrease in the spacing between the upper resin layers. When the lower temperature decreases faster than the upper temperature, it indicates that heat is transferred from top to bottom, and local density adjustments may occur in the lower region of the resin layer. In this process, the curvature change points of the temperature change trend are matched with the micro-displacement points of the resin interface to form a time correlation diagram of temperature change trend and interface change. Through this correlation method, the temporal characteristics and range of changes in the internal state of the resin layer can be determined, providing a clear physical basis for generating rearrangement prompts.
[0029] After comparing and analyzing the temperature change trend with the resin interface changes, a rearrangement indicator is generated based on the coupling relationship between the two types of information. This indicator is formed by comprehensively judging the direction and magnitude of the temperature gradient change and the morphological changes of the resin interface. Specifically, in the temperature change trend, when the temperature difference between the upper and lower layers persists and does not show a trend of convergence, this time period is recorded as a potential period of internal state change; when the resin interface in the image shows slow downward movement, local blurring, or slight bending, this area is marked as a location where internal structural adjustments may occur. By mapping the temperature information identifier with the image information identifier, a rearrangement indicator with spatial location and time interval attributes can be generated. This indicator is used to indicate the time period and area of minor rearrangement occurring inside the resin layer during the settling process, so that the regeneration operation parameters can be adjusted or the low-pressure water flow process can be started in subsequent processes to reduce the uneven regeneration caused by internal rearrangement. Throughout the process, the comparative analysis of temperature change trends and resin interface changes is consistently applied. The generation of rearrangement prompts is based on the dynamic relationship between the two types of information, ensuring a comprehensive reflection and continuous tracking of changes in the internal state of the resin. This enables seamless data integration between information processing in the settling stage and process preparation in the regeneration stage.
[0030] Based on the rearrangement prompts, a low-pressure water flow process is introduced before entering the resin regeneration stage. Water flow reaction information of different areas of the bed is collected during the low-pressure water flow process, and the water flow reaction information is analyzed to generate a flow distribution record reflecting the distribution of abnormal water flow paths. Based on the rearrangement prompts, accurately determine the water flow distribution within the bed before entering the resin regeneration stage. Collect water flow reaction information through a low-pressure water flow process and perform comprehensive analysis to generate a flow distribution record reflecting abnormal water path distribution. The specific implementation steps are as follows: After obtaining the rearrangement indicator markers, the time intervals and spatial locations indicated by the markers are organized and designated as key areas for the low-pressure water flow process. Based on the geometry and operating conditions of the resin regeneration unit, the inlet and outlet locations of the water medium, as well as the initial settings for the water pressure, are determined. The low-pressure water flow setting should be lower than the lower limit of the normal operating pressure of the regenerated liquid to avoid disturbing the resin layer structure while ensuring that the water flow can penetrate the entire bed. Before starting the water flow, the liquid level inside the bed is adjusted so that the water surface is slightly higher than the upper boundary of the resin layer, creating a closed water environment to prevent air from entering and causing flow instability. The water flow device is then turned on, and makeup water is slowly introduced at a constant low pressure, allowing the water to be evenly distributed along the bottom of the bed and permeate upwards. The main purpose of this stage is to allow the water to rise naturally along the original channel path without disrupting the resin stratification, thereby enabling actual observation of the flow characteristics in the area indicated by the rearrangement indicator markers.
[0031] During low-pressure water flow, the flow response at different heights and radial positions within the bed is simultaneously acquired. To this end, flow rate and pressure acquisition units are deployed at the bottom, sidewalls, and top of the bed, respectively. By acquiring instantaneous flow velocity, flow fluctuations, and pressure changes at each location, spatial resolution recording of the water flow process is achieved. Simultaneously, an image acquisition device continuously records visual information such as local interface changes, water turbidity, and bubble rise trajectories during the water flow process, reflecting the water flow path and local disturbance phenomena. The acquired water flow response information includes flow rate curves, pressure distribution curves, and corresponding visual change sequences at different locations. Throughout the entire water flow phase, temperature, pressure, flow rate, and visual information are kept synchronized to ensure that various data can correspond in subsequent analysis, forming a multi-dimensional information foundation for the water flow response.
[0032] After collecting water flow response information, the multidimensional data obtained during the low-pressure water flow phase were processed for spatial correspondence and temporal extension. Pressure and flow rate change curves at different heights were overlaid to identify periods and areas of sudden flow increases or pressure drops. These areas typically correspond to low-resistance water flow channels within the bed. By comparing the flow rate fluctuation amplitude at different radial positions, the non-uniformity of the water flow distribution in the lateral direction of the bed can be determined. When the flow rate fluctuation amplitude in a certain radial area is higher than that in the surrounding areas, it indicates a higher concentration of water flow, representing a potential abnormal water flow path. Simultaneously, the image data obtained from video acquisition was temporally matched with the pressure and flow rate data. The positions of bubble movement trajectories and local disturbances on the resin layer surface were compared to determine the spatial range and morphological distribution of the low-resistance water flow area. By mapping the flow rate curve, pressure curve, and image change sequence onto the bed's spatial coordinates, a spatial distribution structure map of the water flow response can be obtained. This map reflects the positional relationships of the main and secondary water flow channels and relatively static areas during the water flow process, providing data support for generating flow distribution records.
[0033] After obtaining the spatial distribution structure diagram, the water flow reaction information is categorized and summarized according to the longitudinal and radial positions of the bed, forming a flow distribution record. The flow distribution record uses the bed height as the ordinate, the water flow path position as the abscissa, and time as the extension dimension, recording the flow intensity, pressure gradient, and image change characteristics of different regions. Regions with continuous flow fluctuations and relatively low pressure are recorded as low-resistance channels; regions with gradual flow changes and high pressure gradients are recorded as high-resistance regions; and regions where flow fluctuations and image disturbances occur simultaneously are recorded as local non-uniform regions. By marking these regions, a continuous record file reflecting the water flow distribution state within the entire bed can be formed. The flow distribution record includes not only the longitudinal penetration path information of the fluid but also the lateral diffusion trend and temporal evolution law, fully presenting the internal water flow organization morphology during the low-pressure water flow stage. This record provides a basis for optimizing the subsequent regenerated liquid entry sequence, entry intensity, and entry position, establishing a correspondence between the water flow state before regeneration and the internal structure adjustment of the resin layer, thereby achieving a comprehensive understanding and orderly management of the water flow characteristics inside the bed before entering the regeneration stage. Throughout the process, the collection, analysis, and recording of water flow reaction information maintain temporal and spatial continuity, ensuring that the flow distribution record can accurately reflect the internal flow characteristics and path distribution of the makeup water resin regeneration device during the low-pressure water flow stage.
[0034] By using flow distribution records, the entry sequence, entry intensity, and entry location of the regenerated liquid are reconfigured to generate a regeneration entry schedule. By utilizing flow distribution records, the entry sequence, entry intensity, and entry location of the regenerated liquid are rationally configured to generate a regeneration entry schedule that conforms to the actual flow characteristics of the resin bed. The specific implementation steps are as follows: After the flow distribution records were generated, the flow intensity distribution and pressure gradient distribution in different regions of the records were analyzed to determine the hydraulic characteristics of each water passage path within the bed. By stratifying the flow variation intervals in the longitudinal and transverse directions, the internal space of the bed was divided into three regions: high-flow zone, medium-flow zone, and low-flow zone. The high-flow zone corresponds to the path where the flow value is consistently higher than the average flow rate, and is the area where water flow is most concentrated. The medium-flow zone is where the flow variation is close to the average level and the pressure gradient is relatively stable. The low-flow zone is where the flow fluctuation is small and the resistance is high. After determining the spatial location of these three regions, the height range and area ratio of each region were recorded, forming a preliminary division map of the hydraulic channels within the bed. This division map reflects the uneven water distribution and is a prerequisite for reconfiguring the regenerated liquid inlet parameters.
[0035] Based on the hydraulic channel division, the temporal information in the flow distribution records is integrated. Since the flow distribution records reflect the dynamic changes during the low-pressure water flow phase, the distribution of flow paths varies across different time periods, necessitating the inclusion of the temporal dimension in the analysis. By summarizing the temporal extension characteristics of the flow rate change curves in the records, the formation, stabilization, and attenuation processes of the flow paths are segmented and identified. High-flow zones that form and persist in the early stages of water flow are identified as stable main channels; areas appearing in the middle stages with short durations are identified as temporary secondary channels; and areas appearing only at the end of the water flow phase are identified as delayed flow zones. This combined temporal and spatial division method reveals the evolutionary patterns of the flow paths within the bed, providing data support for setting the subsequent regenerated liquid entry sequence. Through this process, the flow distribution records not only characterize the static channel distribution but also reflect the flow activity and interrelationships of each channel at different time stages.
[0036] After completing the temporal and spatial division of the water flow path, the entry sequence, intensity, and location of the regenerated liquid are configured. The configuration process begins by determining the entry sequence. Based on the distribution patterns of the main and secondary channels in the flow distribution record, the entry sequence is adjusted to proceed gradually from the low-flow zone to the high-flow zone, ensuring the regenerated liquid first enters the area with higher resistance, thus promoting uniform fluid distribution in the initial stage. Next, the entry intensity of the regenerated liquid is determined. Based on the flow distribution characteristics of different channels, the entry intensity is divided into three levels: a lower entry intensity is set for the high-flow zone to prevent premature concentrated inflow; a medium entry intensity is set for the medium-flow zone to maintain overall flow stability; and a higher entry intensity is set for the low-flow zone to compensate for the adverse effects of local resistance on fluid penetration. Finally, the entry location of the regenerated liquid is determined. Based on the longitudinal distribution of the channels in the flow distribution record, the entry points of the regenerated liquid are rearranged radially at the bottom of the bed, creating a staggered configuration between the entry locations and the highly active areas of the water flow path, thereby increasing the diffusion distance and coverage area of the liquid flow within the bed. During the configuration process, the flow intensity, pressure gradient, and path direction in the flow distribution record are all used as reference parameters to ensure that the inlet parameters of the regenerated liquid correspond to the hydraulic characteristics inside the bed.
[0037] After configuring the regenerated liquid entry parameters, these parameters are integrated in chronological and spatial order to generate a regeneration entry schedule. This schedule includes elements such as the regenerated liquid entry sequence, entry intensity, entry location, and corresponding duration, arranged along a time axis. For different water flow path types, corresponding regenerated liquid entry time periods are set, creating a segmented rhythm during the entry process. Based on the flow distribution records, the regeneration entry schedule establishes a correspondence between the internal water flow distribution characteristics of the bed and the regeneration operation parameters. Through this schedule, different regenerated liquid entry schemes can be executed sequentially according to the time progress during the regeneration stage, allowing the regenerated liquid flow direction and velocity to change at different stages, thereby achieving a uniform spatial distribution of the regenerated liquid. Throughout the process, the flow distribution records provide the spatial basis for water flow distribution, the parameter configuration forms the operational rules for regenerated liquid entry, and the regeneration entry schedule combines these two into a unified data structure. This structure reflects both the hydraulic state inside the bed and defines the dynamic entry method of the regenerated liquid, providing a clear operational reference for subsequent regeneration stages. Through the above steps, a set of regenerated liquid entry parameter configuration schemes that match the water flow state can be formed before entering the regeneration stage, so that the regeneration process of the resin layer can be coordinated and controlled in both time and space.
[0038] Based on the regeneration schedule, controlled reverse pressure changes are introduced during the resin regeneration process to regulate the water flow in the bed. Based on the regeneration entry schedule, controlled reverse pressure changes are introduced during resin regeneration to regulate the water flow within the bed. The process revolves around the regenerated liquid entry sequence, intensity, and location defined in the schedule, ensuring that the introduction of reverse pressure changes is coordinated with the regenerated liquid flow pattern. This achieves dynamic balance and continuous adjustment of the water flow without damaging the resin bed structure, ensuring a more even distribution of the regenerated liquid throughout the resin bed. The specific implementation steps are as follows: After the regeneration entry schedule is finalized, the initial setting parameters for reverse pressure changes are determined based on the entry stage and flow rate variation characteristics of the regenerated liquid. The regeneration entry schedule provides the time series and spatial distribution of the regenerated liquid entry. By analyzing the flow rate intensity at each stage, the range and timing of the reverse pressure change are determined. Specifically, the pressure in the lower inlet pipeline of the bed is used as the main regulating variable, with the maximum flow rate at the entry stage as the upper limit of the pressure change range and the minimum flow rate at the entry stage as the lower limit. The reverse pressure change is applied during the intermittent phase of the regenerated liquid entry intensity variation, ensuring that the fluid movement inside the bed is in a stable transition state. At this time, by synchronously controlling the regenerated liquid entry rhythm, it can be ensured that the application of reverse pressure changes and the regenerated liquid flow process form an interactive relationship, thereby laying the foundation for pressure control conditions for subsequent water flow regulation.
[0039] After determining the setting parameters for the reverse pressure change, the flow state of the regenerated liquid is adjusted in stages according to the time sequence of the regeneration entry schedule. By controlling the pressure at the inlet and outlet ends, a short-term flow reversal is achieved, disturbing the original water flow path within the bed under brief reverse pressure. During this disturbance, the water flow changes from its original upward direction to a slight downward direction, with the duration controlled between one-tenth and one-fifth of the regenerated liquid flow cycle, ensuring that the pressure change covers the entire resin layer thickness without causing resin mixing. Through this reverse pressure, the water flow within the bed is temporarily interrupted, the water flow in the low-resistivity flow area is forced to disperse, and the original high-flow path is redistributed under the short-term reverse impact. This process buffers the flow difference between the local stagnant areas and the main flow areas within the resin layer, creating a more uniform flow basis for the next stage of forward regenerated liquid entry.
[0040] After completing the first round of reverse pressure changes, intermittent reverse pressure regulation continues according to the entry intensity and location of the next stage in the regeneration entry schedule. At this time, the amplitude and duration of the reverse pressure are fine-tuned based on the changes in the water flow status of the previous stage. For stages with high regenerated liquid entry intensity, the amplitude of the reverse pressure is appropriately increased to expand the disturbance range; for stages with low regenerated liquid entry intensity, the amplitude of the reverse pressure is decreased to avoid excessive flow fluctuations. In this way, the reverse pressure changes correspond to the rhythm of regenerated liquid entry, ensuring that each stage of flow adjustment targets key areas in the flow distribution. Simultaneously, during the reverse pressure changes, the pressure difference and flow distribution at the upper and lower positions of the bed are monitored in real time to confirm the scope and duration of the reverse pressure changes, thereby maintaining the continuity and controllability of the entire regeneration process. By repeatedly implementing controlled reverse pressure changes, multiple fine adjustments to the water flow status can be made at different points in the regeneration stage, maintaining a balanced water flow distribution within the bed.
[0041] Before the end of the entire regeneration process, the records of reverse pressure changes and the regeneration entry schedule are compiled to form a water flow state adjustment record. This record, organized chronologically, correlates the amplitude and duration of each reverse pressure change with the corresponding regenerated liquid entry stage, reflecting the trajectory of water flow changes within the bed throughout the regeneration process. This record clearly demonstrates the gradual impact of reverse pressure changes on the water flow state, including the reorganization of water flow paths, the diffusion of local channels, and the formation of overall flow equilibrium. The water flow state adjustment record not only plays a dynamic control role during the regeneration stage but also serves as a basis for subsequent operational optimization, providing traceable operational data support for the makeup water resin regeneration process. Throughout this process, the amplitude of reverse pressure changes remains within a controllable range, and the pressure adjustment process is synchronized with the order, intensity, and location of regenerated liquid entry, ensuring that the water flow within the bed remains stable and adjustable. Through this series of operations, reverse pressure changes achieve phased adjustment of the water flow state, ensuring continuous and uniform flow of the regenerated liquid within the resin layer, providing a reliable technical guarantee for process control during the resin regeneration stage.
[0042] This invention introduces the synchronous acquisition and dynamic analysis of multi-dimensional parameters during the resin regeneration settling stage, enabling continuous sensing and correlation judgment of temperature distribution, water flow changes, and resin interface conditions within the bed. This allows for the creation of a linked record that accurately reflects the evolution of the internal state during settling. This method effectively avoids information lag caused by relying on manual observation, allowing for the early identification of minute changes within the resin layer. It provides data for liquid flow distribution during the regeneration stage, transforming the regeneration process from passive observation to active monitoring, thus improving the controllability and operational safety of the resin regeneration process.
[0043] This invention reconfigures the entry sequence, intensity, and location of the regenerated liquid based on flow distribution records, and introduces controlled reverse pressure changes during the regeneration phase to continuously regulate and equalize the liquid flow path within the bed. This method eliminates short-circuiting of the regenerated liquid caused by local low-resistance channels during regeneration, ensuring full contact between the regenerated liquid and the resin layer, promoting uniform regeneration reaction, thereby improving resin regeneration quality, reducing regenerated liquid consumption, and ensuring the long-term stability of the makeup water system and the consistency of regeneration results.
