Description

Technical Field

[0001] This application relates to the technical field of secondary water supply for pipe networks, and particularly to a descaling device for a secondary water supply system of a pipe network. Background Art

[0002] Secondary water supply mainly compensates for the lack of pressure in municipal water supply pipelines to ensure the daily water use of people living and working in high-rise buildings. Most descaling devices adopt a fixed alloy ratio or a single-function design, making it difficult to adapt to the complex water quality of the secondary water supply system of the pipe network, such as hard water, flow rate fluctuations, temperature changes, etc.

[0003] At the same time, in the traditional secondary water supply system, its structure lacks adjustment ability, resulting in a decrease in descaling efficiency with the change of working conditions. It also lacks real-time monitoring and intelligent maintenance functions, relying on manual regular inspections, with high maintenance costs.

[0004] For example, the Chinese patent discloses "A secondary water supply device with a descaling function" (Patent No.: CN222161445U). This patent includes a physical structure such as a filter screen to achieve the cleaning of dirt without interrupting water supply, and the cleaning process is simple. However, this physical filtration method has problems such as easy blockage and frequent cleaning, and the cleaning effect on the stubborn water scale already attached to the inner wall of the pipeline is limited.

Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] An embodiment of the present invention provides a scale removal device for a secondary water supply system of a pipe network, as Figure 1-9As shown in the figure, it includes a secondary water supply storage tank 101, an arched support bracket 103, a main water outlet pipe 105, and a water inlet interface 136. There are several arc-shaped support plates 102 at the bottom of the secondary water supply storage tank 101. Several arched support brackets 103 are fixedly connected to the bottom of the arc-shaped support plates 102. The arched support brackets 103 are distributed in an array. A support base 104 is fixedly provided at the bottom of the arched support bracket 103. There is a water storage cavity 139 inside the secondary water supply storage tank 101. The main water outlet pipe 105 is communicated with one side at the bottom of the water storage cavity 139. The water inlet interface 136 is communicated with one side at the front end of the water storage cavity 139. There is a spiral water inlet device 1001 on one side of the secondary water supply storage tank 101. The spiral water inlet device 1001 includes a spiral water inlet pipe 127. The head end of the spiral water inlet pipe 127 is communicated with a water inlet pipe connector 142. The water inlet pipe connector 142 is communicated with the water inlet interface 136. The tail end of the spiral water inlet pipe 127 is communicated with a raw water input pipe 125. A multi-alloy filter plate 146 is installed in the raw water input pipe 125. The spiral water inlet device 1001 is used to input the water supply to be stored into the water storage cavity 139 inside the secondary water supply storage tank 101. The tail end of the main water outlet pipe 105 is connected to a three-way pipe 109. The other side of the three-way pipe 109 is communicated with a bypass pipe 110. One end of the bypass pipe 110 is connected to a backflow monitoring component 1002. The backflow monitoring component 1002 is used to pump the water supply flowing through the bypass pipe 110 and form a backflow. The backflow monitoring component 1002 includes a circulation water pump 111. The side of the circulation water pump 111 is communicated with the bypass pipe 110.

[0025] It should be further noted that the multi-alloy filter plate 146 is made of a gradient alloy combination of zinc, copper, magnesium, and titanium. Uniformly distributed through holes are provided on the surface of the multi-alloy filter plate 146.

[0026] It is worth further noting that the spiral water inlet pipe 127 is designed in a spiral corrugated shape. When water flows through it, controllable turbulence is generated. The turbulent shear force destroys the layered growth of the scale crystal nuclei. At the same time, the turbulence accelerates the diffusion of micro-currents, so that the scope of the electrochemical action extends from the inner core surface to the entire pipeline area.

[0027] Furthermore, two scale inhibition electrode plates 140 are installed in the water storage cavity 139. An elastic support framework 141 is provided inside the scale inhibition electrode plates 140 on both sides. Two electrochemical anode groups 118 are fixedly provided at the top of the secondary water supply storage tank 101. Conductive contacts are provided at the bottom of the electrochemical anode groups 118 on both sides. The bottom of the electrochemical anode group 118 is connected to the scale inhibition electrode plate 140.

[0028] It should be further noted that the elastic support framework 141 is designed in a honeycomb structure, and a shape memory alloy (such as nickel-titanium alloy) is built-in as the support framework.

[0029] Further, a power supply 122 is installed and connected to the top of the electrochemical anode group 118. The power supplies 122 are electrically connected through signal connection lines 123. On one side of the top of the secondary water supply storage tank 101, a power supply controller 124 is installed. The signal connection line 123 is electrically connected to the power supply controller 124.

[0030] It should be further noted that the power supply controller 124 provides power support for the start-up of the electrochemical anode group 118, and a signal processing module is provided in the power supply controller 124.

[0031] Further, on one side above the inner wall of the water storage chamber 139, three curved return pipes 121 are communicated and arranged. The curved return pipes 121 are distributed in an array. The curved return pipes 121 are in a bent shape. At the top of the three-sided curved return pipes 121, a horizontally arranged return header 120 is communicated. A number of intelligent control valves 117 are provided at the top of the return header 120. The intelligent control valves 117 are arranged at the communication position between the curved return pipes 121 and the return header 120. The intelligent control valves 117 are used to control the on-off situation between the return header 120 and the curved return pipes 121.

[0032] It should be further noted that the intelligent control valves 117 are forged from 316L stainless steel. A signal processing module is provided in the return header 120. The signal processing module is signal-connected to the intelligent control valves 117 on each side. After receiving the signal, it controls the start-up of the intelligent control valves 117 at the corresponding positions and connects the curved return pipes 121 to the return header 120.

[0033] Further, the return monitoring assembly 1002 further includes a detection buffer tank 138 arranged above the circulation water pump 111. The top of the detection buffer tank 138 is communicated with a return output pipe 116. The return output pipe 116 is installed and communicated with the side water inlet of the return header 120.

[0034] Further, a return input pipe 113 is communicated between the back of the detection buffer tank 138 and the circulation water pump 111. A control detection processor 145 is provided on the back of the detection buffer tank 138. A control detection module is provided in the control detection processor 145. Through the water quality sensor arranged inside, it is used to monitor the scale concentration content in the return water input from the return input pipe 113.

[0035] It is worth further noting that when the circulation water pump 111 starts, it can pump the stored water flowing from the main water outlet pipe 105 into the bypass pipe 110 into the circulation water pump 111 through the bypass pipe 110, and output it upward through the return input pipe 113 to the detection buffer tank 138 for further detection work.

[0036] It should be further noted that the control detection module in the control detection processor 145 performs signal control output through the pre-input threshold.

[0037] Further, a sewage ejector 114 is connected to the front end of the detection buffer tank 138. A sewage pipeline 106 for output is installed and connected to the front end of the sewage ejector 114, and a sewage controller 115 is installed at the top of the sewage ejector 114.

[0038] It should be noted that the sewage ejector 114 is designed as a tapered nozzle, which generates a high-speed jet during sewage discharge, forming a local negative pressure area and enhancing the discharge efficiency of the inorganic scale in the output liquid in the detection buffer tank 138.

[0039] It should be further noted that the sewage pipeline 106 is connected to the sewage pipeline. A signal structure processing module is provided in the sewage controller 115, and it is connected to the control and detection module of the control and detection processor 145 through LORA communication for control signal connection. When receiving the control signal in the control and detection processor 145, the sewage controller 115 controls and opens the connection between the sewage ejector 114 and the detection buffer tank 138 to achieve the sewage discharge effect.

[0040] It is worth further noting that the power controller 124 and the control and detection processor 145 are connected for data through LORA communication.

[0041] Further, a three-way electromagnetic switching valve 108 is installed and connected in the three-way pipeline 109, and an electric signal switch 107 is installed at the top of the three-way electromagnetic switching valve 108.

[0042] It should be further noted that the electric signal switch 107 and the control and detection processor 145 are connected for data through LORA communication.

[0043] It is worth further noting that under normal conditions, the connection amount between the three-way pipeline 109 and the bypass pipe 110 can divert 10% - 20% of the water output in the three-way pipeline 109 into the bypass pipe 110, and the subsequent circulating water pump 111 is started to pump the return water upward through the return input pipe 113 into the detection buffer tank 138 for monitoring. If the monitoring is okay, the return water is input into the return manifold 120 through the return output pipe 116. At this time, the intelligent control valve 117 closest to the detection buffer tank 138 is controlled to start to connect the curved return pipe 121 and the return manifold 120, so as to realize the reflow of the return water back into the water storage cavity 139 of the secondary water supply storage tank 101 for the next secondary water supply output. If there is a problem with the monitoring, at this time, the electric signal switch 107 controls the output of the three-way pipeline 109 to be closed, and the main water outlet pipe 105 and the bypass pipe 110 are all connected.

[0044] Such as Figure 6-8As shown, the spiral water inlet 1001 also includes an arc-shaped protective plate 126 arranged on one side of the outer end surface of the spiral water inlet pipe 127. The arc-shaped protective plate 126 is semicircular, and a detection guide rail 144 opening outward is provided on the top of the arc-shaped protective plate 126. An ultrasonic thickness gauge probe 134 is slidably provided in the detection guide rail 144. A signal transmission line 137 is installed and connected to one side of the ultrasonic thickness gauge probe 134, and the signal at the tail end of the signal transmission line 137 is connected to a data analyzer 129.

[0045] It should be further explained that the ultrasonic thickness measuring probe 134 is used to monitor the thickness of the scale layer in the pipeline in real time. Through data analysis, the scale inhibition effect in the pipeline can be evaluated and potential scaling problems can be discovered in time.

[0046] Furthermore, a driving bracket 130 with a horizontal frame is fixed on both sides of the outer end surface of the arc-shaped protection plate 126, and a movable guide rail 131 is fixed on the top of the driving bracket 130. A movable slider 133 is provided in the movable guide rails 131 on both sides. A transmission screw 132 is rotatably provided in the movable guide rail 131. The transmission screw 132 is threadedly connected to the movable slider 133. An arc-shaped connecting rod 135 is fixed on the top of the movable slider 133. The arc-shaped connecting rod 135 is installed and connected to the end surfaces on both sides of the ultrasonic thickness measuring probe 134.

[0047] It is worth further explaining that a moving motor is provided in the moving guide rail 131, and the moving motor is power-connected to the transmission screw 132. When the moving motor is started, it can drive the transmission screw 132 to rotate, and then drive the moving slider 133 to move along the moving guide rail 131 through a threaded connection, and then drive the ultrasonic thickness measuring probe 134 to move back and forth through the support connection of the arc-shaped connecting rod 135. The reciprocating movement of the ultrasonic thickness measuring probe 134 realizes spiral stepping scanning, ensuring the monitoring of the inner wall of the spiral water inlet pipe 127 without blind spots, measuring the thickness of the scale layer, and outputting the data through the data analyzer 129.

[0048] It should be further explained that all connections between pipes in the device are made by flange structure connection, using high-pressure butt-welding flanges, loose flanges and threaded flanges. The high-pressure butt-welding flanges are used to connect the main water inlet pipes such as the spiral water inlet pipe 127 and the water inlet pipe connector 142, the spiral water inlet pipe 127 and the raw water input pipe 125. The material is 316L stainless steel, which is suitable for chloride ion corrosion environment.

[0049] It should be further explained that the loose flange is used in the bypass pipe 110 and the circulating water pump 111, the detection buffer tank 138 and the reflux output pipe 116 and other locations with frequent vibrations, and adopts the Q235B carbon steel + PTFE lining structure to withstand the vibration displacement generated by the operation of the circulating water pump 111.

[0050] It should be further noted that the threaded flange is used for sensor interfaces such as the electrical signal switch 107 and the control and detection processor 145, and the material is brass plated with nickel to ensure the stability of signal transmission.

[0051] When using this solution, first drive the secondary water supply storage tank 101 to the installation position of the secondary water supply system in the community or building, and use the arched support feet 103 and the support base 104 to stably support the secondary water supply storage tank 101. At this time, install and connect the main outlet pipe 105 with the end connected to the tee pipe 109, and install and connect the reflux monitoring component 1002 with the bypass pipe 110. Then, install and connect one side of the reflux output pipe 116 with the end of the reflux header 120. Then, install the spiral water inlet 1001 on one side of the secondary water supply storage tank 101, install and connect the water inlet connector 142 with the water inlet interface 136, install and connect the raw water input pipe 125 with the water supply pipe, install and connect the tee pipe 109 with the secondary water supply pipe in the community or building, and connect the sewage pipe 106 with the sewage pipe.

[0052] Subsequently, when performing the work of storing water supply inside the secondary water supply storage tank 101, first input the water supply through the raw water input pipe 125 and enter the spiral water inlet pipe 127 after passing through the multi-alloy filter plate 146. Due to the spiral corrugated design of the spiral water inlet pipe 127, controllable turbulence is generated when the water flows through. The turbulent shear force destroys the layered growth of the scale crystal nuclei. At the same time, the turbulence accelerates the diffusion of the microcurrent, so that the scope of the electrochemical action extends from the inner core surface to the entire pipeline area.

[0053] At the same time, because the multi-alloy filter plate 146 is made of a gradient alloy combination of zinc, copper, magnesium, and titanium, the outer layer is high-potential metals (copper, titanium), and the inner layer is low-potential metals (zinc, magnesium), forming a gradient potential difference. The gradient potential enhances the microcurrent intensity and expands the range of ionic charge interference. Then, after the gradient alloy contacts the water medium, zinc / magnesium (inner layer) is preferentially corroded as the anode, releasing electrons to form a microcurrent loop through copper / titanium (outer layer), changing the crystallization kinetics of calcium carbonate, making aragonite replace calcite precipitation, and reducing the adhesion of the scale layer.

[0054] Subsequently, after the water supply is stored inside the water storage cavity 139 of the secondary water supply storage tank 101, uniform water distribution is achieved through the honeycomb structure of the scale inhibitor electrode plate 140. When secondary water supply output is required, the stored water in the water storage cavity 139 is output outward through the main water outlet pipe 105 into the tee pipe 109, and the stored water is output for use through the secondary water supply pipe in the community or building connected to the tee pipe 109. The connection volume between the tee pipe 109 and the bypass pipe 110 can divert 10% - 20% of the water output in the tee pipe 109 into the bypass pipe 110, and the subsequent circulation water pump 111 is started to pump the return water upward through the return input pipe 113 into the detection buffer tank 138 for monitoring. If there is no problem with the monitoring, the return water is input into the return manifold 120 through the return output pipe 116. At this time, the intelligent control valve 117 closest to the detection buffer tank 138 is controlled to start, connecting the curved return pipe 121 to the return manifold 120, thereby realizing the reflow of the return water back into the water storage cavity 139 of the secondary water supply storage tank 101 for the next secondary water supply output.

[0055] If there is a problem with the return water flowing through the detection buffer tank 138 as monitored by the water quality sensor, at this time, the electric signal switch 107 controls the output of the tee pipe 109 to be closed, and fully connects the main water outlet pipe 105 and the bypass pipe 110. At the same time, the detection processor 145 is controlled to increase the frequency of the detection buffer tank 138 from the normal default state, and accelerate the extraction of the return water in the bypass pipe 110. At the same time, the detection processor 145 is controlled to output a pulsed square wave to the electrochemistry anode group 118 through signal control connection with the power controller 124, increasing the microcurrent density. At the same time, the shape memory alloy of the elastic support framework 141 is activated to generate high-frequency microvibrations. The combined effect improves the scale layer peeling rate. At the same time, the intelligent control valves 117 on each side are started, and the return water flows back into the return manifold 120 through the return output pipe 116, and then into the curved return pipe 121, realizing the internal water quality circulation. During the circulation process, the return water with ionic charges repeatedly flushes the surface of the elastic support framework 141, realizing the physical scale removal work inside the water storage cavity 139. At the same time, during this process, the sewage controller 115 is controlled to start, and through the design of the tapered nozzle of the sewage ejector 114, a high-speed jet flow is generated during sewage discharge, forming a local negative pressure area, enhancing the discharge efficiency of the inorganic scale in the output liquid in the detection buffer tank 138.

[0056] After the self-cleaning scale removal work is started for a period of time, when the control detection processor 145 monitors that the water quality problem no longer changes, at this time, the electric signal switch 107 switches back to the normal water supply state.

[0057] Meanwhile, during daily use, the moving motor in the moving guide rail 131 is periodically started. The moving motor is power-connected to the transmission lead screw 132. When the moving motor starts, it can drive the transmission lead screw 132 to rotate, and then drive the moving slider 133 to move along the moving guide rail 131 through threaded connection. Furthermore, it drives the ultrasonic thickness measurement probe 134 to reciprocate through the support connection of the arc-shaped connecting rod 135. Through the reciprocating movement of the ultrasonic thickness measurement probe 134, spiral step-by-step scanning is realized to ensure the dead-angle-free monitoring of the inner wall of the spiral water inlet pipe 127, measure the scale thickness, and send the monitoring information of the data analyzer 129 to the operation and maintenance platform for early warning through the LORA communication technology. When the scale thickness affects normal operation, the staff can be notified to replace it in time.

[0058] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
