Description

Technical Field

[0001] The invention relates to the technical field of industrial water supply, and in particular to an industrial water supply system. Background Art

[0002] In industrial production, a stable, reliable and efficient water supply system is a key factor to ensure smooth production. At the same time, domestic water in the factory also needs to be properly supplied. At present, traditional water supply systems often rely on simple pipe connections and manual control, which is difficult to meet the complex and changing industrial needs.

[0003] For example, the industrial water supply pipeline system of a factory of our company is laid from the living area from south to north; around the north wall of the factory, it first goes to the chemical plant, methanol plant and finally to the steam turbine of the power plant. Due to the low terrain on the north side and the high terrain on the south side, the circulating water replenishment of the steam turbine of the power plant is at the end of the pipeline. The pipeline drop is large, and water replenishment is often difficult. The overall water supply network pressure must be increased to meet the needs. In addition, the pipeline at the north wall is low in terrain and buried deep. The pipeline has a long service life and is severely corroded, and leaks frequently occur. Repairing leaks requires outsourcing civil engineering to dig the leaks, and then stopping the water supply pump to repair and treat the leaks, resulting in frequent start and stop of the water supply pump and frequent failures of the soft start equipment. At the same time, the leaks are difficult to locate, and the effect of pipeline repair is not ideal, and water leaks still occur frequently; it has caused a certain impact on the company's production system. In addition, the flow pressure of the main pipeline is displayed on-site, without automatic adjustment function, resulting in waste and loss of the company's industrial water supply resources, causing certain economic losses to the company.

[0004] In order to ensure the safety and stability of the company's industrial water supply system, reduce the level difference of the water supply pipeline, reduce the frequent start and stop of the water supply pump, reduce the frequency of water supply pipeline maintenance, reduce inspection and maintenance and civil engineering costs, and save labor and auxiliary material costs; the expert group unanimously approved the optimization and upgrade of the company's industrial water supply pipeline system.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-3 An industrial water supply system includes a main pipe connected to a water source and several branch pipes connecting the main pipe and a water-using end; wherein each branch pipe is provided with a branch valve near the connection position with the main pipe to independently control the on-off of each branch; the main pipe is responsible for conveying the water source, and the branch pipe diverts the water to specific application sites.

[0039] In order to ensure efficient operation of the system, the layout of branch pipes must follow the following principles: Reasonable planning: The connection location of the branch pipe should be scientifically planned according to the specific location of the water point and water demand; elbows and unnecessary length should be minimized to reduce water loss and resistance; Height control: Try to make the downstream branch lower than the upstream branch to form a natural drop, which is beneficial to water flow and system stability.

[0040] A pressure regulating valve and a total flow meter are provided at the input end of the main pipe.

[0041] Both are key components to ensure the stable operation of the water supply system; by adjusting the opening of the pressure regulating valve, the total water pressure of the water supply system is accurately adjusted to ensure that the water supply pressure is stable within an appropriate range; through the total flow meter, the flow data of the main pipe is monitored in real time to provide a basis for the overall flow control of the system.

[0042] It is understandable that the pressure regulating valve is equipped with a pressure gauge to provide real-time pressure feedback and data for system operation, which is convenient for monitoring and adjustment.

[0043] Correspondingly, the branch pipes are provided with branch pressure gauges and branch flow meters to measure the water consumption of the branch pipes separately.

[0044] At the same time, components such as the pressure regulating valve, main flow meter, sub-pressure gauge, branch flow meter, etc. are all connected to the control room for communication to achieve intelligent and remote control; and to achieve overall control of the entire water supply system.

[0045] Specifically, the branch valves are adjusted or opened and closed according to actual conditions to achieve precise control of the water supply to the branch pipes; the branch pressure gauges monitor the water pressure in the branch pipes in real time to ensure stable pressure at each water use point; the branch flow meters record the flow data of the branch pipes to provide data support for the system's flow control and water use management.

[0046] It is understandable that the pressure regulating valve, main flow meter, sub-pressure gauge, branch flow meter and sub-valve components are all electronically controlled and can be digitally transmitted. The sub-valve of each branch pipe is remotely controlled to open and close according to demand conditions to regulate the water supply of the system as a whole; for example, when the water supply is insufficient, some branches are given priority.

[0047] In addition, when using: By comparing the sum of the branch flow meters with the difference between the total flow meter, it is possible to determine whether there is a leak.

[0048] Specifically, the branch flow meter data of each branch pipe is transmitted to the control system in the control room; after summary calculation, it is compared with the data of the main flow meter; if it exceeds a reasonable range, it is judged that the water supply system has a fault such as leakage.

[0049] It is understandable that components such as pressure regulating valves, main flow meters, sub-pressure gauges, branch flow meters, and sub-valves are connected to the control room through communication lines or wireless communications; operators can intuitively understand the operating status of the entire water supply system through display screens or instruments in the control room, and perform remote control according to actual needs. Among them, the communication between each component and the control system can be in the form of DCS cards, PLC controllers, industrial computers, etc., so as to achieve data communication and control.

[0050] also: The control system can automatically adjust the opening of the pressure regulating valve and the sub-valve through data analysis to achieve the best water supply effect (for example, if the water demand increases, the valve will be opened, and if the water demand is small, the valve will be closed accordingly); By continuously collecting various data during the operation of the system, including pressure, flow, real-time water demand, water demand during a time period, etc., potential patterns and problems in the data can be mined to provide decision support for system optimization and maintenance (for example, if a branch pipe has many abnormal conditions, more attention should be paid to it and its maintenance should be strengthened; if the pressure at a certain location fluctuates frequently, a pressure stabilizing mechanism should be set up accordingly, etc.); The optimal control strategy can be generated based on the corresponding analysis of the real-time status of the system and historical data, realizing intelligent management of the system (for example, pre-adjusting the water supply status of each location based on historical water use data, and conducting comprehensive regulation in combination with overall water use); In addition, when an abnormality is detected, an alarm can be issued to remind operators to take appropriate measures to avoid further expansion of the fault.

[0051] In this plan: A pressure regulating valve and pressure gauge are installed at the water inlet end of the main pipe to achieve precise pressure regulation of the water supply system, ensuring that the water supply pressure is stable within an appropriate range to meet the needs of different industrial production links and domestic water use.

[0052] The total flow meter is combined with the sub-flow meter to realize comprehensive monitoring of water flow; the flow of the main pipe and branch pipe is monitored in real time, and the overall control is carried out to further ensure the stability of the flow of each branch pipe, providing accurate data support for the system's flow control and water management; Can calculate and analyze leakage and other abnormal conditions; through flow calculation, abnormal conditions can be discovered in time; The control room is used for unified control; each component is connected to the control room through communication, and the operator can centrally monitor the operating status of the entire water supply system in the control room, realize remote control, and improve work efficiency; Highly automated and intelligent control; the central control system combines real-time data with historical data to achieve automatic regulation and intelligent management, further improving the reliability, stability and efficiency of the water supply system.

[0053] In some embodiments, segmented flow meters are respectively provided upstream and downstream of the connection position between the main pipe and each branch pipe.

[0054] When in use, by comparing the difference between the upstream and downstream flow meters of each section, it is possible to measure whether there is leakage between sections; that is, to measure whether there is leakage in the main section between two branch pipes. Thus, it is possible to quickly locate which section the leak is located.

[0055] It is understood that the segmented flow meter is also communicatively connected to the control room and provides data support for the control system.

[0056] In some embodiments, the main pipe is further connected to a plurality of water replenishment tanks.

[0057] As an additional part of the industrial water supply system, the water make-up tank is mainly used to cope with high water demand in a short period of time and ensure the stability and reliability of the water supply system: it cooperates with the overall regulation to achieve temporary supplement and improvement of water supply.

[0058] It can be understood that the water replenishment tank is planned and arranged as a whole based on the water consumption, water pressure requirements and other information of each branch pipe; the water replenishment tank is mainly arranged near the branch pipes with high requirements for water pressure and stable water supply, so as to provide additional water replenishment when the water pressure is insufficient to ensure the normal supply of industrial water.

[0059] Accordingly, the water inlet end of the water replenishment tank is connected to the upstream of the main pipe, and the water outlet end is connected to the downstream of the main pipe, or directly connected to one or more branch pipes; the water supply path of the water replenishment tank can be flexibly adjusted to improve the adaptability of the system.

[0060] At the same time, a water level meter is installed in the water replenishment tank, and the water level meter is connected to the control room for communication to monitor the water storage situation; branch valves and branch flow meters are installed on the water inlet pipe and outlet pipe of the water replenishment tank, and are connected to the control room for communication to facilitate remote control and monitoring.

[0061] It can be understood that through the setting of the water replenishment tank, a certain amount of water can be stored to cope with the high water consumption in a certain period of time; and, in conjunction with the overall regulation of the control system, the water replenishment tank can be dynamically and pre-planned to store water and supply water to the outside, further ensuring the stability and reliability of the water supply system.

[0062] For example, the positions of branches are arranged according to the water consumption and water pressure requirements of each branch, and dynamic adjustments are made during use to ensure stable water pressure in important branches.

[0063] In some embodiments, a pressurization branch is also provided on the branch pipe.

[0064] The booster branch is an additional component specially designed for certain branches that require higher water pressure, or to deal with insufficient water supply pressure. The booster pump is used to adjust the pressure of a specific branch to ensure that its water supply demand is met.

[0065] Among them, the boosting branch is a C-type pipeline connecting two points of the branch pipe; an electric control valve and a boosting pump are installed on the C-type pipeline to adjust the water pressure in the branch pipe; a check valve is installed on the branch pipe between the inlet and outlet points of the C-type pipeline to prevent water backflow and ensure the boosting effect; during use, the pressure of the branch water supply is regulated by the operation of the boosting pump.

[0066] In addition, the upstream end of the C-type pipe is also connected to a water replenishment tank to quickly provide additional water when needed.

[0067] like Figure 2 As shown, valves are provided on the C-type pipeline to adjust different water supply pipelines.

[0068] It is understandable that the working status of the booster pump and the water pressure data in the branch pipe are transmitted to the control room in real time for easy monitoring and adjustment.

[0069] In some embodiments, the branch pipe further includes: a domestic water branch.

[0070] The domestic water branch is a branch pipe specially used to provide domestic water. It is also equipped with water quality monitoring sensors, water purifiers, sewage tanks and other components to ensure the safety and hygiene of the water supply.

[0071] Among them, water quality monitoring sensors can monitor the water quality parameters of domestic water in real time, such as pH value, turbidity, residual chlorine, etc., to ensure that the water quality meets the standards; water purifiers are used to filter impurities and harmful substances in the water and improve water quality. The treated water is then transported to various domestic water points; sewage tanks are used to collect wastewater generated by water purifiers and connected to the main pipes or non-domestic water branches for recycling.

[0072] Among them, a set of water quality monitoring sensors can be set up upstream and downstream of the water purifier.

[0073] It should be noted that the operating status of the domestic water branch needs to be strictly controlled and monitored to ensure the quality and safety of water supply; the working status of water quality monitoring sensors and water purifiers is transmitted to the control room in real time, and operators can monitor water quality parameters and equipment operating status through components such as display screens and instruments; when water quality parameters exceed the standard or equipment fails, the system will immediately issue an alarm to remind operators to take corresponding measures to ensure water supply safety.

[0074] In some embodiments, the branch pipe is also connected to a circulating water tank, a sewage tank, and other functional structures to meet different industrial water needs.

[0075] Specifically, the circulating water pool is mainly used to collect and treat circulating water generated in the industrial production process, realize the reuse of water resources, and improve the economy and environmental protection of the system. It should have basic functions such as water recovery and water quality treatment; the circulating water pool collects cooling water, cleaning water, etc. generated in the production process, and after treatment, it is transported to the production line for use; in addition, the circulating water pool is equipped with components such as filtering devices, sedimentation tanks and disinfection equipment to remove impurities and harmful substances in the water to ensure that the water quality meets the standards and can be circulated again.

[0076] Sewage pools are mainly used to collect and treat sewage generated in industrial production processes to ensure that its discharge meets environmental protection standards; sewage pools collect wastewater generated in the production process, such as cleaning wastewater, chemical reaction wastewater, etc.; sewage pools are usually equipped with sedimentation tanks, filtration devices and chemical treatment equipment to remove harmful substances in the water and ensure that the water quality meets the standards; in addition, sewage pools are also equipped with sludge concentration tanks and dewatering equipment to treat the precipitated sludge, reduce the sludge volume, and facilitate subsequent treatment and disposal.

[0077] like Figure 3 The figure shows a partial management diagram of the renovation. After the renovation, the safety and stability of the company's industrial water supply system have been improved, the frequency of water supply pipeline maintenance has been reduced, and the company's auxiliary material costs and water supply electricity costs have been saved.

[0078] The water supply system realizes automatic control and intelligent management.

[0079] 1) Through the integrated control system, the entire water supply system can be automatically controlled to improve the operating efficiency and stability of the system; 2) Data collection and analysis: The system continuously collects various data during operation, including pressure, flow, real-time water demand, water demand in a certain period of time, etc.; through data analysis, it mines the potential patterns and problems in the data to provide decision support for system optimization and maintenance; for example, it can predict future water demand based on historical water use data and adjust the water supply status in advance; 3) Automatic control: The optimal control strategy can be automatically generated based on real-time data and historical data; for example, the opening of the pressure regulating valve and the sub-valve can be automatically adjusted to achieve the best water supply effect; 4) Intelligent expansion: By introducing artificial intelligence and big data technologies, the intelligent management level of the system can be further improved to achieve more efficient resource utilization and energy conservation: 5) Predictive analysis: Machine learning algorithms can be used to analyze historical water use data, predict future water use trends, and prepare for water supply in advance; 6) Fault prevention: By continuously monitoring the operating status of the equipment, potential fault risks can be identified and preventive measures can be taken in advance to avoid faults.

[0080] 7) Optimized scheduling: Water supply distribution can be dynamically adjusted according to real-time water demand and equipment status to achieve optimal utilization of resources.

[0081] The water supply system has good comprehensive benefits and great promotion value.

[0082] 1) Improve water supply stability: through precise pressure regulation and flow control, ensure the stable operation of the water supply system to meet the needs of different industrial production links and domestic water; 2) Reduce operating costs: By optimizing scheduling and preventing faults, the number of equipment maintenance and repairs can be reduced, thereby reducing operating costs; 3) Improve resource utilization efficiency: Through the setting of circulating water pools and sewage pools, water resources can be reused and sewage can be discharged in compliance with standards, thus improving resource utilization efficiency; 4) Ensure environmental safety: Through strict water quality monitoring and sewage treatment, ensure that water supply and discharge meet environmental protection standards and protect environmental safety.

[0083] In some embodiments, a filter section is further provided at the input end of the main pipe; flanges are provided at both ends of the filter section and can be detachably assembled on the main pipe; and the incoming water is simply treated by the filter section added in front.

[0084] Specifically, Figure 4-16 As shown; the filtering section includes: an outer pipe section 1, a paddle 3 and a spiral filter screen 4 which are arranged inside the outer pipe section 1, connected through a main shaft 2, and driven as a whole, and a filtering temporary storage bin 5 located in front of the spiral filter screen 4.

[0085] There are multiple spiral filter screens 4 arranged around the main shaft 2, and the spiral filter screens 4 have less than 0.5 turns, so as to avoid the formation of large inclined surface obstruction.

[0086] At the same time, the spiral direction of the spiral filter 4 is opposite to the shape of the blade 3; under the impact of the water flow, the blade 3 drives the spiral filter 4 to rotate, and the spiral filter 4 transports the filtered debris against the water flow to the filtering temporary storage bin 5.

[0087] It should be noted that the spiral filter 4 is a spirally twisted mesh body with less resistance to water flow; its function is to intercept some debris, appropriately prevent the speed of the debris moving backward, and transport some debris against the water flow to the filtering temporary storage bin 5.

[0088] Correspondingly, the filtering temporary storage bin 5 is connected to the outside of the lower half pipe arranged in the outer pipe section, and a sewage pipe 51 is obliquely arranged at the lower end thereof.

[0089] like Figure 6 As shown; some debris falls into the temporary filter storage bin 5; which is lower than the main body of the outer pipe section 1 and can temporarily accommodate some debris and discharge it regularly through the sewage pipe 51.

[0090] It is understandable that a valve is provided on the sewage pipe 51, which is closed in normal state and opened when sewage needs to be discharged. Under the impact of water flow, the temporarily stored debris is quickly discharged.

[0091] It should be noted that Figure 6 This is just an example of a sewage pipe structure; other forms of structures that can discharge debris are also possible.

[0092] When in use, the water flow from upstream impacts the paddle 3, causing it to drive the main shaft 3 to rotate, and synchronously drive the spiral filter 4; the spiral filter 4 is different from the paddle 3 in spiral shape, producing a conveying effect against the water flow; thereby, the filtered debris slows down its backward movement speed, and some of the debris can also be conveyed to the filter temporary storage bin 5.

[0093] It should be noted that a limiting ring is also provided at the rear end of the inner part of the outer pipe section 1; the limiting ring protrudes inwards to prevent the spiral filter screen 4 from moving backwards.

[0094] In some embodiments, the outer ring of the spiral filter 4 is also fixedly connected to an annular filter 6 that matches the inner diameter of the outer pipe section, so as to better ensure stability during rotation.

[0095] Furthermore, a plurality of strip-shaped openings 61 are axially provided on the annular filter screen 6 .

[0096] At the same time, a sewage pipe 62 is arranged at the lower end of the outer pipe section 1 corresponding to the position of the annular filter screen 6 .

[0097] Thus, part of the debris falls into the sewage pipe 62 through the strip-shaped opening 61, and cooperates with the forward transportation to better intercept and collect part of the debris.

[0098] In addition, the upstream of the sewage pipe 62 is connected to the filtering temporary storage bin 5, and a sewage discharge valve pipe is provided downstream, thereby forming a larger temporary storage space and providing multiple sewage discharge methods.

[0099] In some embodiments, the filter segment further includes: a second segment 7; the second segment 7 is assembled with the tail end of the outer tube segment 1 through a flange.

[0100] It should be noted that the outer tube segment 1 and the second segment 7 can be used together or independently; multiple outer tube segments 1 and second segments 7 can also be provided in combination to form a stronger combination.

[0101] Specifically, a vertically arranged flat filter plate 8 is inserted in the second segment 7 .

[0102] Meanwhile, a vertical pipe 9 connected to the outside of the second segment is disposed at the lower end of the flat filter plate 8 .

[0103] The debris intercepted by the flat filter plate 8 falls downward into the vertical pipe 9 and is discharged outward at regular intervals.

[0104] Preferably, the vertical pipe 9 is a flat structure, and a plate valve is provided at its lower end, which is more compatible with the shape of the flat filter plate 8.

[0105] The flat filter plate 8 includes an outer frame 81 and a mesh body 82 arranged in the outer frame 81 .

[0106] Furthermore, a notch is provided in the lower end plate of the outer frame 81 to connect the second segment 7 with the vertical pipe 9 .

[0107] When in use, the debris is intercepted on the upstream side of the net body 82; at the same time, under the scouring effect of the water flow, it falls into the vertical pipe 9.

[0108] It should be noted that interception and collection can be achieved with only this arrangement; however, due to the formation of a "dead water" state in the vertical pipe 9, the aggregation effect is relatively poor; in order to solve this defect, further improvements have been made.

[0109] That is, a return pipe 91 is also provided on the rear side of the vertical pipe 9 in communication.

[0110] Specifically, the upstream end of the return pipe 91 is located above the plate valve and is provided with a filter screen; the downstream end of the return pipe 91 is bent upward and connected to the downstream of the second segment.

[0111] As a result, in addition to the backward path of the flat filter plate 8, the water flow also forms a branch that flows into the downstream through the return pipe 91. When in use, the debris is intercepted by the flat filter plate 8 and then flushed into the vertical pipe 9 by a downward water flow. It is again intercepted by the filter screen at the end of the return pipe 91 and gathered in the vertical pipe 9. The plate valve of the vertical pipe 9 is opened regularly to discharge sewage.

[0112] In some embodiments, an inspection port 71 is provided above the second segment 7 ; the inspection port 71 is sealed by a sealing plate 72 .

[0113] At the same time, the upper end of the flat filter plate 8 is assembled with the sealing plate 72 by bolts, so as to facilitate the inspection and replacement of the flat filter plate 8.

[0114] In the aforementioned embodiment, the added filter section does not require external power or energy, and is completely driven by the internal flowing water; the unique reverse thrust form produces a better filtering effect; the combined outer pipe section 1 and the second section 7 can be freely matched to form a stronger combination state; the vertical pipe 9 cooperates with the return pipe 91 to form a diversion, which has a stronger and more reliable collection effect; the inspection port 71 is matched with the sealing plate 72, which is convenient for maintenance and replacement.

[0115] In the present invention, the water supply system is integrated with automation technology and intelligent management system, which can achieve precise pressure regulation, efficient flow control, timely leakage detection and flexible remote monitoring; it can not only better serve production activities, but also significantly improve resource utilization efficiency, reduce operating costs and ensure environmental safety.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
