Description

Technical Field

[0001] This invention relates to the field of power plant wastewater treatment technology, and more specifically, to a method and system for power plant boiler water treatment based on WTC reverse osmosis technology. Background Technology

[0002] During power plant operation, traditional processes have shortcomings in water resource utilization. The large amount of concentrate produced by reverse osmosis contains high concentrations of salt, organic matter, and impurities, and direct discharge results in water waste and environmental pollution. With technological advancements, a recycling method has been invented to further treat the concentrate using reverse osmosis to obtain usable product water. Product water reuse improves water resource utilization efficiency and significantly reduces concentrate discharge, achieving the requirement of "water conservation and water purification" simultaneously as outlined in the "Water Ten Measures." This method can resolve the dilemma of expanding system product water capacity and reducing concentrate discharge.

[0003] However, existing secondary reverse osmosis processes still have some problems. Given the significant differences in concentrate quality between different power plants and even within the same plant at different times, the water quality characteristics are complex and variable. The non-uniform retention of various salts during the reverse osmosis process alters scaling characteristics, increasing the risk of scaling. Organic matter and scale inhibitors in the raw water are largely concentrated during the primary reverse osmosis treatment, further deteriorating the concentrate quality. This complex and variable water quality makes conventional concentrate reverse osmosis systems difficult to adapt effectively, greatly limiting the widespread application of concentrate reuse technology. Due to the inability to precisely treat specific water conditions, some local thermal power plants have had to shorten chemical cleaning cycles, resulting in frequent chemical cleaning. This not only accelerates membrane element wear and shortens their lifespan but also significantly increases operation and maintenance costs, severely hindering the efficient application and promotion of concentrate reuse technology in power plants. Summary of the Invention

[0004] Therefore, this invention provides a method and system for treating boiler water in power plants based on WTC reverse osmosis technology, in order to solve the technical problems in the prior art where the membrane elements have low anti-fouling ability, are prone to clogging, require frequent chemical cleaning, and have short lifespan due to water quality differences in reverse osmosis processes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Based on big data, several sets of concentrated water samples were collected and analyzed to obtain data parameters such as ion concentration, organic matter content, microbial quantity and activity, and to construct a concentrated water quality analysis dataset.

[0009] A local concentrate information database is constructed. By matching and comparing the data parameters with those in the concentrate water quality analysis dataset, differentiated water quality parameters are selected to determine the expected treatment targets.

[0010] Based on the expected treatment objectives, the selection and arrangement of special membrane elements are determined, and the corresponding architecture of the WTC reverse osmosis process concentrate treatment system is planned. Data parameters are monitored and controlled for the expected treatment objectives, and the control results are recorded in real time to adaptively adjust to the expected treatment objectives.

[0049] The system construction control module is used to construct the WTC reverse osmosis process concentrate treatment system architecture;

[0050] The concentrated water big data acquisition module is used to collect several sets of concentrated water data based on big data for detection and analysis, to obtain data parameters such as the concentration of various ions, the content of organic matter, the number and activity of microorganisms, and to construct a concentrated water quality analysis dataset.

[0054] 1. This application method compares the concentrate quality analysis dataset obtained from local databases and big data collection. By leveraging differentiated water quality parameters, it identifies potential problems in the subsequent concentrate treatment process and the parameter-related causes of these problems. Through the construction of a WTC reverse osmosis (RO) process concentrate treatment system architecture, targeted planning is implemented for the concentrate to be treated. This allows for the precise use of corresponding membrane element types and arrangements, reducing the likelihood of problems and risks during concentrate treatment. Simultaneously, by detecting targeted data parameters, the WTC RO concentrate treatment system architecture can be rapidly adjusted based on the data, improving the timeliness of concentrate treatment and ensuring the service life of components within the system. This effectively enhances the membrane element's anti-fouling capability and system stability, extends membrane element lifespan, reduces the frequency of chemical cleaning, and lowers maintenance costs, thereby promoting the efficient application of concentrate reuse technology in power plants.

[0055] 2. This device enhances the membrane element's resistance to specific chemicals by applying a coating to the separation membrane, reducing static electricity buildup on the membrane surface and preventing the electrostatic adsorption of dust, impurities, and other contaminants, thus lowering the risk of membrane fouling. The device also utilizes a cleaning supply structure to clean the membrane element structure. Specifically, by passing through a buffer zone within the membrane element, a relatively slower flow rate concentrates debris that would otherwise be evenly distributed across the membrane assembly within the buffer zone. Perforations further concentrate the residue, preventing large amounts of debris from remaining on the separation membrane. Since the cleaning action is primarily concentrated in the slow-flow area, unnecessary cleaning impact on the entire membrane element is reduced, helping to protect other parts of the membrane element structure. This further reduces damage to the membrane element structure and performance caused by frequent cleaning or severe fouling, significantly extending the overall service life of the device and improving its overall functionality and practicality.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0073] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0074] like Figures 1 to 9 As shown in the figure, this invention provides a method for power plant boiler water treatment based on WTC reverse osmosis technology, including the following steps:

[0075] S1: Construct a WTC reverse osmosis process concentrate treatment system architecture to treat concentrate with different parameters in power plant boilers, thereby flexibly responding to different water treatment needs;

[0076] The specific process is as follows:

[0077] Please refer to Figures 2 to 8The WTC reverse osmosis concentrate treatment system architecture includes a membrane element structure 1, a cleaning supply structure 2, and a detection structure 3. The cleaning supply structure 2 enables cleaning of the membrane element structure 1. Specifically, through the buffer section 16 within the membrane element structure 1, a relatively slower flow rate concentrates debris that would otherwise be evenly distributed across the membrane assembly within the buffer section 16. Further, the residue is concentrated through the perforations 211, preventing a large amount of debris from remaining on the separation membrane 12. Since the cleaning action is primarily concentrated in the slow-flow area, unnecessary cleaning impact on the entire membrane element is reduced, helping to protect other parts of the membrane element structure 1. This further reduces damage to the membrane element structure 1 and its performance caused by frequent cleaning or severe fouling, significantly extending the overall service life of the device and improving its overall functionality and practicality. Specific settings are as follows:

[0078] Please refer to Figure 2 and Figure 3 The membrane element structure 1 includes a porous central tube 11 and a membrane assembly wound around the outer periphery of the porous central tube 11. The porous central tube 11 is a hollow circular tube, and its circular side has several permeate holes for allowing permeate to enter and exit the porous central tube 11. The membrane assembly includes separation membranes 12, with a flow guide grid 13 between two separation membranes 12, and a permeate grid 14 on the innermost separation membrane 12. The separation membranes 12 are wound around the porous central tube 11. Please refer to [reference needed]. Figure 3 At least one outer surface of the separation membrane 12 is provided with a coating 15. Depending on the actual concentrate situation, when treating concentrate with different parameter data, coatings including but not limited to polydopamine, polyvinyl alcohol, or some composite coatings can be fixed on the outer surface of the separation membrane 12 to enhance the tolerance of the separation membrane 12 to specific chemicals. At the same time, by increasing the static electricity accumulation on the surface of the separation membrane 12, it can effectively prevent the static electricity adsorption of dust, impurities, and other contaminants, thereby reducing the risk of contamination of the separation membrane 12.

[0079] Please continue to refer to this. Figure 3The coating 15 is provided with a buffer section 16. Specifically, the buffer section 16 includes a slow-flow protrusion 161 along the side of the separation membrane 12. The extension direction of the slow-flow protrusion 161 is consistent with the winding direction of the separation membrane 12. The separation membrane 12 is wound around the peripheral side of the porous central tube 11 to form a flow channel. The slow-flow protrusion 161 blocks the flow channel, so as to form a narrower flow channel at the protrusion of the slow-flow protrusion 161, forming a buffer area with a lower concentrate flow rate. The lower flow rate in the buffer section 16 area increases the contact area and contact time between the concentrate and the separation membrane 12, so that more pollutants are retained near the slow-flow protrusion 161. Compared with other places on the separation membrane 12, the pollutants will be concentrated at the slow-flow protrusion 161, which is convenient for centralized treatment by the cleaning supply structure 2, thereby improving the pollutant treatment efficiency.

[0080] Please refer to Figure 4 The cleaning supply structure 2 includes a backwashing component 21 and a gas supply component. The gas supply component includes an air compressor 22 and an air inflation control system 23. The air inflation control system 23 can use, but is not limited to, a PLC to control the opening and closing of the air compressor 22 and the gas flushing pressure. The air inflation control system 23 is connected to the detection system structure 3. The detection system structure 3 is used to detect the pressure and flow rate before and after the membrane element. The real-time internal pressure of the membrane element structure 1 is obtained through the detection system structure 3 to avoid excessive pressure or excessive flushing time, which could damage the separation membrane 12 and ensure the service life of the separation membrane 12.

[0081] Please refer to Figure 4 and Figure 5 The backwashing component 21 is located on the outer periphery of the porous central tube 11, and the backwashing component 21 corresponds to the position of the buffer section 16. The backwashing component 21 is a hollow annular body. The porous central tube 11 is provided with a limiting ring groove 114 that cooperates with the inner ring of the backwashing component 21. The outer ring of the backwashing component 21 is provided with a flushing hole 211. The backwashing component 21 is provided with a first connecting connector 212 that communicates with the gas supply component. The gas supply component communicates with the flushing component through the first connecting connector 212 to discharge the flushing gas from the flushing hole 211 of the backwashing component 21 to the buffer section 16. The contaminants in the buffer section 16 are removed from the separation membrane 12 under the impact of the gas and continue to flow along the backflow channel, thereby reducing the contaminants on the separation membrane 12, ensuring the membrane flux of the separation membrane 12, reducing the cleaning frequency of chemical cleaning, and further ensuring the service life of the separation membrane 12.

[0082] As a preferred embodiment, please continue to refer to... Figure 3The buffer section 16 further includes a plurality of guide strip-shaped protrusions 162. The guide strip-shaped protrusions 162 are arranged in an array along the extension direction of the slow-flow protrusions 161, and the extension direction of the guide strip-shaped protrusions 162 is perpendicular to the extension direction of the slow-flow protrusions 161. The guide strip-shaped protrusions 162 are wavy, and some of the guide strip-shaped protrusions 162 intersect with the slow-flow protrusions 161. The guide strip-shaped protrusions 162 are used to slow down the flow of concentrated water along the winding direction of the separation membrane 12, thereby improving the retention efficiency of the buffer section 16 for pollutants in the concentrated water, improving the ability of the buffer section 16 to retain pollutants, achieving a high concentration of pollutants, and increasing the centralized processing capacity of the cleaning supply structure 2.

[0083] As a preferred embodiment, please continue to refer to... Figure 5 The porous central tube 11 has a first end plate 111 and a second end plate 112 at its two ends respectively. The inner side of the first end plate 111 is provided with a backwashing component 21. The buffer part 16 is provided at one end of the separating membrane 12 near the first end plate 111. The first end plate 111 and the second end plate 112 are both circular plates. The first end plate 111 and the second end plate 112 are provided with a flow guide grid and a central hole for the porous central tube 11 to pass through, so as to achieve uniform distribution of concentrate into the flow channel entering the membrane element. By setting the buffer part 16 at the end of the concentrate flow, the influence of the buffer part 16 on the overall flow rate of the concentrate is reduced, the flow rate of the concentrate in the membrane element is guaranteed, and the clogging rate of pollutants is reduced.

[0084] As a preferred embodiment, please refer to Figure 6 , Figure 7 and Figure 8The WTC reverse osmosis process concentrate treatment system architecture also includes a concentrate transport membrane housing 4. The concentrate transport membrane housing 4 has a channel in its middle for inserting the membrane element structure 1. The concentrate transport membrane housing 4 has a concentrate outlet 41 for concentrate to flow out of the concentrate housing 4, a concentrate inlet 42 for concentrate to enter the concentrate transport membrane housing 4, a product water outlet 43 connected to the orifice center tube 11, and a sealing port 44 to prevent concentrate from entering the backwashing component 21. The first end plate 111 has a first connector protrusion 1111 for the first connector 212 to protrude from. The second end plate 112 is provided with a second connector outlet 1121, and the backwashing component 21 is also provided with a second connector 213. The second connector 213 extends to the second connector outlet 1121 through an extension pipe 214. In this embodiment, the porous central tube 11 is provided with a plurality of elongated holes 113 extending from the backwashing component 21 to the second end plate 112. The elongated holes 113 are used to allow the extension pipe 214 to extend to the second connector outlet 1121. While avoiding the extension pipe 214 from changing the outer diameter and shape of the porous central tube 11, it also replaces the water production hole of the porous central tube 11 to achieve the function of water production entry.

[0085] The membrane element structure 1 is at least one set, and the membrane element structures 1 are arranged sequentially inside the concentrate transport membrane shell 4. The separation membrane sheet 12 in each membrane element structure 1 can be coated with different materials 15 to address scenarios where the concentrate contains multiple different parameters. The second connector 213 on the innermost membrane element structure 1 is sealed and mated with the sealing port 44. The first connector 212 on the innermost membrane element structure 1 is mated and mated with the first connector 212 on the adjacent membrane element. The second connector 213 on the adjacent membrane element structure 1 is sequentially mated and mated with the first connector 212 on the next adjacent membrane element. The porous central tube 11 on the adjacent membrane element structure 1 is mated and mated with each other. The first connector 212 on the outermost membrane element structure 1 is connected to the cleaning supply structure 2. The connection of multiple membrane element structures 1 forms a longer reverse osmosis structure to increase the reverse osmosis effect on the concentrate, thereby further improving the treatment effect of the device on the concentrate.

[0086] Please refer to Figure 8 The first end plate 111 and the second end plate 112 are both provided with limiting protrusions 17. The inner wall of the concentrate transport membrane shell tube 4 is provided with a limiting groove 45 that cooperates with the limiting protrusions 17. Through the cooperation of the limiting protrusions 17 and the limiting grooves 45, the angle at which each membrane element structure 1 is placed into the concentrate transport membrane shell tube 4 is realized, thereby ensuring the front and rear membrane element structures 1 and ensuring the overall stability of the device.

[0087] Please refer to Figure 7 and Figure 8 The detection system structure 3 includes a first temperature detection element 31, a first pressure detection element 32, a second pressure detection element 33, a third pressure detection element 34, a first flow rate detection element 35, and a second flow rate detection element 36. The first temperature detection element 31 is located inside the concentrate transport membrane housing 4 to ensure that the temperature inside the concentrate transport membrane housing 4 is always within a suitable range, thus avoiding impact on the membrane element's lifespan and the characteristics of the concentrate. The first pressure detection element 32 is located at the concentrate inlet 42, the second pressure detection element 33 is located at the concentrate outlet 41, and the third pressure detection element 34 is located at the product water outlet 43. The first flow rate detection element... The first component 35 is located at the concentrate inlet 42, and the second flow detection element 36 is located at the concentrate inlet 42. By detecting the pressure and flow rate before and after the concentrate transport membrane housing 4, and the pressure and flow rate before and after the membrane element, the system can prevent excessive pressure or excessive pressure from causing wear on the flow channel and contaminant deposition. The detection system structure 3 detects the pressure difference and flow rate difference before and after the membrane element. When the pressure difference and flow rate difference reach the preset opening value, the cleaning supply structure 2 flushes the buffer section 16 with gas through the flushing hole on the backflushing component 21. When the pressure difference and flow rate difference reach the preset closing value, the cleaning supply structure 2 closes the flushing of the buffer section 16.

[0088] S2: Based on big data, several sets of concentrated water are collected for detection and analysis to obtain data parameters such as the concentration of various ions, the content of organic matter, the number and activity of microorganisms, and to construct a concentrated water quality analysis dataset. The data parameters obtained from the concentrated water quality analysis dataset are processed, and the concentrated water data parameters that have problems during the concentrated water treatment process and those that have not have problems are statistically analyzed separately. After statistical integration, the data parameters of the concentrated water with problems such as increased risk of scaling and easy pollution are obtained.

[0089] S3: Construct a local concentrate information database, use water quality testing instruments to obtain data parameters of local power plant boiler concentrate, match and compare with data parameters in the concentrate water quality analysis dataset, screen out differentiated water quality parameters, determine the expected treatment target, and thus obtain the main causes of problems that may occur in the concentrate to be treated, including but not limited to the problem of high concentrations of calcium and magnesium ions, which indicates a significant increase in the risk of scaling.

[0090] S4: Based on the expected treatment target, determine the selection and arrangement of special membrane elements, and plan the WTC reverse osmosis process concentrate treatment system architecture accordingly. Monitor and control the data parameters for the expected treatment target, and record the control results in real time to adaptively adjust to the expected treatment target.

[0091] By comparing local databases with big data collection to obtain concentrated water quality analysis datasets, and leveraging differentiated water quality parameters, potential problems in the subsequent concentrated water treatment process and the parameter causes of these problems in the concentrated water are identified. By constructing a concentrated water treatment system architecture for the WTC reverse osmosis process, targeted planning is implemented for the concentrated water to be treated, enabling the precise use of corresponding membrane element types and arrangements. This reduces the possibility of problems and risks during concentrated water treatment. Simultaneously, through targeted data parameter monitoring, the WTC reverse osmosis concentrated water treatment system architecture can be quickly adjusted based on data, improving the timeliness of concentrated water treatment and ensuring the service life of components within the WTC reverse osmosis concentrated water treatment system architecture, significantly reducing operation and maintenance costs.

[0092] This invention also provides a power plant boiler water treatment system based on the above-described WTC reverse osmosis process for power plant boiler water treatment, specifically comprising:

[0093] The system construction control module is used to construct the WTC reverse osmosis process concentrate treatment system architecture;

[0094] The concentrated water big data acquisition module is used to collect several sets of concentrated water based on big data for detection and analysis, to obtain data parameters such as the concentration of various ions, the content of organic matter, the number and activity of microorganisms, and to construct a concentrated water quality analysis dataset.

[0095] The local concentrate data analysis module is used to build a local concentrate information database. By matching and comparing the data parameters with those in the concentrate water quality analysis dataset, it filters out differentiated water quality parameters and determines the expected treatment targets.

[0096] The concentrate treatment and planning module is used to determine the selection and arrangement of special membrane elements based on the expected treatment objectives, and to plan the WTC reverse osmosis process concentrate treatment system architecture accordingly. It monitors and controls data parameters for the expected treatment objectives and records the control results in real time to adaptively adjust to the expected treatment objectives.
