Description

Technical Field

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

[0002] Secondary water supply is mainly used to compensate for the lack of pressure in municipal water supply pipelines and to ensure daily water supply for people living in high-rise buildings. Most anti-scaling devices use fixed alloy ratios or single-function designs, which are 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, the traditional secondary water supply system lacks structural adjustment capabilities, resulting in a decrease in anti-scaling efficiency as working conditions change.

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] The embodiment of the present invention provides a descaling device for a secondary water supply system of a pipe network, such as Figure 1-9As shown, it includes a secondary water supply storage tank 101, an arched support frame 103, a main water outlet pipe 105 and a water inlet interface 136. The bottom of the secondary water supply storage tank 101 is provided with a plurality of arc-shaped arc support plates 102, and a plurality of arched support frames 103 are fixedly connected to the bottom of the arc support plates 102. The arched support frames 103 are arranged in an array. A support base 104 is fixedly provided at the bottom of the arched support frames 103. A water storage chamber 139 is provided in the secondary water supply storage tank 101. The main water outlet pipe 105 is connected to one side of the bottom of the water storage chamber 139.

The head end of the spiral water inlet pipe 127 is connected to an inlet. Water pipe connector 142, the water inlet pipe connector 142 is connected to the water inlet interface 136, the tail end of the spiral water inlet pipe 127 is connected to a raw water input pipe 125, and a multi-element alloy filter plate 146 is installed in the raw water input pipe 125. The spiral water inlet 1001 is used to input the water supply to be stored into the water storage chamber 139 in 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, and the other side of the three-way pipe 109 is connected to 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 draw in the water supply flowing through the bypass pipe 110 and form a backflow. The backflow monitoring component 1002 includes a circulating water pump 111, and the side of the circulating water pump 111 is connected to the bypass pipe 110.

[0035] It should be further explained that the multi-element alloy filter plate 146 is made of a gradient alloy combination of zinc, copper, magnesium and titanium, and the surface of the multi-element alloy filter plate 146 is provided with evenly distributed through holes.

[0036] It is worth further explaining that the spiral water inlet pipe 127 is designed as a spiral corrugation, which generates controllable turbulence when water flows through. The turbulent shear force destroys the layered growth of scale crystal nuclei. At the same time, the turbulence accelerates the diffusion of microcurrent, extending the range of electrochemical action from the inner core surface to the entire pipeline.

[0037] Furthermore, two scale-inhibiting electrode plates 140 are installed in the water storage chamber 139, and elastic support frames 141 are provided in the scale-inhibiting electrode plates 140 on both sides. Two electrochemical anode groups 118 are fixed on the top of the secondary water supply storage tank 101, and 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-inhibiting electrode plate 140.

[0038] It should be further explained that the elastic support frame 141 is designed as a honeycomb structure, with a built-in shape memory alloy (such as nickel-titanium alloy) as the support frame.

[0039] Furthermore, a power supply 122 is installed on the top of the electrochemical anode group 118, and the power supplies 122 are electrically connected to each other through a signal connection line 123. A power controller 124 is installed on one side of the top of the secondary water supply storage tank 101, and the signal connection line 123 is electrically connected to the power controller 124.

[0040] It should be further explained that the power controller 124 provides power support for starting the electrochemical anode group 118 , and a signal processing module is provided in the power controller 124 .

[0041] Furthermore, three curved return pipes 121 are provided on one side above the inner wall of the water storage chamber 139. The curved return pipes 121 are distributed in an array and are curved. The top ends of the curved return pipes 121 on three sides are connected to a horizontal return collection pipe 120. Several intelligent control valves 117 are provided on the top end of the return collection pipe 120. The intelligent control valves 117 are provided at the connecting position between the curved return pipe 121 and the return collection pipe 120. The intelligent control valves 117 are used to control the on-off status of the return collection pipe 120 and the curved return pipe 121.

[0042] It should be further explained that the intelligent control valve 117 is forged from 316L stainless steel, and a signal processing module is provided in the return manifold 120. The signal processing module is connected to the intelligent control valves 117 on each side through signals. After receiving the signal, the intelligent control valve 117 at the corresponding position is controlled to start, and the curved return pipe 121 is connected to the return manifold 120.

[0043] Furthermore, the reflux monitoring component 1002 also includes a detection buffer tank 138 arranged above the circulating water pump 111. The top of the detection buffer tank 138 is connected to a reflux output pipe 116, and the reflux output pipe 116 is installed and connected to the side water inlet of the reflux manifold 120.

[0044] Furthermore, a reflux input pipe 113 is provided between the back of the detection buffer tank 138 and the circulating water pump 111, and a control detection processor 145 is provided on the back of the detection buffer tank 138. The control detection processor 145 is provided with a control detection module, which is used to monitor the scale concentration content in the return water input from the reflux input pipe 113 through the internally arranged water quality sensor.

[0045] It is worth further explaining that when the circulating water pump 111 is started, the stored water flowing from the main water outlet pipe 105 through the bypass pipe 110 can be pumped into the circulating water pump 111 through the bypass pipe 110, and output upward through the reflux input pipe 113 to the detection buffer tank 138 for further detection work.

[0046] It should be further explained that the control detection module in the control detection processor 145 performs signal control output according to a pre-input threshold value.

[0047] Furthermore, the front end of the detection buffer tank 138 is connected to a sewage ejector 114 , the front end of the sewage ejector 114 is connected to a sewage pipe 106 having an output effect, and the top of the sewage ejector 114 is installed with a sewage controller 115 .

[0048] It should be noted that the sewage ejector 114 is designed as a tapered nozzle, which generates a high-speed jet when discharging sewage, forming a local negative pressure area, thereby enhancing the discharge efficiency of inorganic scale in the output liquid in the detection buffer tank 138.

[0049] It should be further explained that the sewage pipe 106 is connected to the sewage pipe, and a signal structure processing module is provided in the sewage controller 115, and a control signal is connected to the control detection module of the control detection processor 145 through LORA communication. When the control signal in the control detection processor 145 is received, the sewage controller 115 controls and opens the connection between the sewage injector 114 and the detection buffer tank 138, thereby achieving a sewage discharge effect.

[0050] It is worth further explaining that the power controller 124 and the control detection processor 145 are data connected via LORA communication.

[0051] Furthermore, a three-way electromagnetic switching valve 108 is installed in the three-way pipe 109 , and an electric signal switch 107 is installed on the top of the three-way electromagnetic switching valve 108 .

[0052] It should be further explained that the data connection between the electrical signal switch 107 and the control detection processor 145 is achieved through LORA communication.

[0053] It is worth further explaining that, under normal conditions, the connectivity between the three-way pipe 109 and the bypass pipe 110 can divert 10% to 20% of the output water in the three-way pipe 109 into the bypass pipe 110, and the subsequent circulating water pump 111 is started to draw 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 side of the detection buffer tank 138 controls the start-up to connect the curved return pipe 121 with the return manifold 120, thereby enabling the return water to flow back into the water storage chamber 139 of the secondary water supply storage tank 101 for the next secondary water supply output. If there is a problem with the monitoring, the electrical signal switch 107 controls the output of the three-way pipe 109 to be closed, and the main water outlet pipe 105 and the bypass pipe 110 are fully connected.

[0054] like 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 face of the spiral water inlet pipe 127. The arc-shaped protective plate 126 is semicircular, and a detection guide rail 144 with an outward opening is provided at the top of the arc-shaped protective plate 126. An ultrasonic thickness measuring probe 134 is slidingly provided in the detection guide rail 144. A signal transmission line 137 is installed on one side of the ultrasonic thickness measuring probe 134, and the signal at the tail end of the signal transmission line 137 is connected to a data analyzer 129.

[0055] 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 a timely manner.

[0056] Furthermore, a horizontal driving bracket 130 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 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, and 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.

[0057] 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.

[0058] It should be further explained that all connections between pipes in this 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.

[0059] It should be further explained that the loose flange is used in locations with frequent vibrations such as the bypass pipe 110 and the circulating water pump 111, the detection buffer tank 138 and the reflux output pipe 116, and adopts a Q235B carbon steel + PTFE lining structure to withstand the vibration displacement generated by the operation of the circulating water pump 111.

[0060] It should be further explained that the threaded flange is used for the interface between the electrical signal switch 107 and the sensor such as the control detection processor 145, and the material is nickel-plated brass to ensure the stability of signal transmission.

[0061] When using this solution, first move the secondary water supply storage tank 101 to the secondary water supply system setting location in the community or building, and use the arch support frame 103 and the support base 104 to provide a stable support effect for the secondary water supply storage tank 101. At this time, the main water outlet pipe 105 connected at the tail end is installed and connected to the three-way pipe 109, and the backflow monitoring component 1002 is installed and connected to the bypass pipe 110. Then, one side of the backflow output pipe 116 is installed and connected to the tail end of the backflow collection pipe 120. Then, the spiral water inlet 1001 is installed on one side of the secondary water supply storage tank 101, and the water inlet pipe connector 142 is installed and connected to the water inlet interface 136, and the raw water input pipe 125 is installed and connected to the water supply pipe, the three-way pipe 109 is installed and connected to the secondary water supply pipe in the community or building, and the sewage pipe 106 is connected to the sewage pipe.

[0062] Subsequently, when the water supply is stored inside the secondary water supply storage tank 101, the water is first input through the raw water input pipe 125 and passes through the multi-alloy filter plate 146 and then enters the spiral water inlet pipe 127. 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 nucleus. At the same time, the turbulence accelerates the diffusion of microcurrent, so that the electrochemical action range extends from the inner core surface to the entire pipeline.

[0063] At the same time, since the multi-alloy filter plate 146 is made of a gradient alloy combination of zinc, copper, magnesium and titanium, the outer layer is a high-potential metal (copper, titanium) and the inner layer is a low-potential metal (zinc, magnesium), a gradient potential difference is formed. The gradient potential enhances the micro-current intensity and expands the ion charge interference range. After the gradient alloy contacts the water medium, zinc / magnesium (inner layer) corrodes preferentially as the anode, releasing electrons to form a micro-current loop through copper / titanium (outer layer), changing the crystallization kinetics of calcium carbonate, causing aragonite to precipitate instead of calcite, and reducing the adhesion of the scale layer.

[0064] Subsequently, when the water supply is stored in the water storage chamber 139 in the secondary water supply storage tank 101, the water is evenly distributed through the honeycomb structure of the scale-inhibiting electrode plate 140. When the secondary water supply needs to be output, the stored water in the water storage chamber 139 is output to the three-way pipe 109 through the main water outlet pipe 105, and the stored water is output for use through the secondary water supply pipe in the community or building connected by the three-way pipe 109. The connectivity between the three-way pipe 109 and the bypass pipe 110 can divert 10% to 20% of the output water in the three-way pipe 109 into the bypass pipe 110. The bypass pipe 110 is filled with water, and the subsequent circulating water pump 111 is started to draw the reflux water upward through the reflux input pipe 113 into the detection buffer tank 138 for monitoring. If there is no problem with the monitoring, the reflux water is input into the reflux header 120 through the reflux output pipe 116. At this time, the intelligent control valve 117 closest to the side of the detection buffer tank 138 is controlled to start and connect the curved reflux pipe 121 with the reflux header 120, thereby realizing the reflux water flowing back into the water storage chamber 139 of the secondary water supply storage tank 101 for the next secondary water supply output.

[0065] If the return water flowing through the detection buffer tank 138 has problems as detected by the water quality sensor, the electric signal switch 107 controls the output of the three-way pipe 109 to be closed, and the main water outlet pipe 105 and the bypass pipe 110 are fully connected. At the same time, the detection processor 145 is controlled to increase the frequency of the detection buffer tank 138 from the normal default, and speed up the extraction of the return water in the bypass pipe 110. At the same time, the detection processor 145 is controlled to connect with the power controller 124 through the signal control. The power controller 124 outputs a pulse square wave to the electrochemical anode group 118 to increase the microcurrent density and activate the shape memory alloy of the elastic support skeleton 141 to generate high-frequency microvibration. The combined action increases the scale layer stripping rate, and at the same time, the intelligent control valves 117 on each side are started, and the return water is returned to the return collection pipe 120 through the return output pipe 116, and then returns to the curved return pipe 121, thereby realizing internal water quality circulation. In the circulation process, the return water with ion charge repeatedly flushes the surface of the elastic support skeleton 141 to realize physical descaling inside the water storage chamber 139. At the same time, in this process, the sewage controller 115 controls the start-up, and through the design of the tapered nozzle of the sewage ejector 114, a high-speed jet is generated during sewage discharge, forming a local negative pressure area, thereby enhancing the discharge efficiency of inorganic scale in the output liquid in the detection buffer tank 138.

[0066] After the self-cleaning descaling work is started for a period of time, when the control detection processor 145 detects that the water quality problem no longer changes, the electrical signal switch 107 switches back to the normal water supply state.

[0067] At the same time, during daily use, the moving motor in the moving guide rail 131 is set to start periodically, and the moving motor is connected to the transmission screw 132 for power. 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 arc-shaped connecting rod 135 support connection. The reciprocating movement of the ultrasonic thickness measuring probe 134 realizes spiral stepping scanning to ensure that there is no blind spot monitoring of the inner wall of the spiral water inlet pipe 127, and measure the thickness of the scale layer. Through the LORA communication technology, the monitoring information of the data analyzer 129 is sent to the operation and maintenance platform for early warning. When the thickness of the scale layer affects normal operation, it can be replaced in time by notifying the staff.
