Description

Technical Field

[0001] The present invention relates to the technical field of water supply, and in particular to a water supply method and a water supply system with low water supply energy consumption. Background Art

[0002] In today's society, efficient use of energy and environmental protection have become a global consensus. As an important part of urban infrastructure, the energy consumption of water supply systems has always attracted much attention. Under existing technical conditions, the problem of high energy consumption in water supply still exists, which not only affects the operational efficiency of the water supply system, but also increases energy waste and environmental pollution. The details are as follows: 1. Limitations of water pump technology: Water pumps are key equipment in water supply systems, and their energy consumption accounts for a large proportion of the energy consumption of the entire water supply system. However, existing water pump technology has limitations in energy saving. Traditional water pump designs often lack optimization for specific working conditions, resulting in high energy consumption during operation.

[0003] (II) Limitations of water supply network: The design of water supply network has an important impact on the energy consumption of water supply system. Under the existing technical conditions, some water supply network designs have problems such as excessively long pipe length and excessively large cross-section, which will increase water flow resistance and lead to increased energy consumption. In addition, water leakage in the pipe network is also an important reason for high energy consumption. Water leakage will not only cause waste of water resources, but also increase the operating load of the water supply system, thereby increasing energy consumption.

[0004] (III) Insufficient informationization: In the existing water supply system, insufficient informationization is also an important reason for high energy consumption. The traditional water supply system management model often relies on manual inspection and scheduling, lacking real-time and accurate data support. This not only affects the operational efficiency of the water supply system, but also increases energy consumption and fails to achieve intelligent management and scheduling of the water supply system.

[0005] (IV) Energy-saving awareness: In addition to technical factors, energy-saving awareness is also an important factor affecting the high energy consumption of water supply. In some areas, there is a lack of initiative and enthusiasm for energy saving and consumption reduction, which leads to some unnecessary waste and loss, and increases the energy consumption of the water supply system.

[0006] In summary, the problem of high energy consumption in water supply under existing technologies involves multiple aspects, so it is necessary to take comprehensive measures from multiple angles to improve and optimize it. Summary of the invention

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] In the description of the present invention, it should be noted that the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0024] The terms "first", "second", etc. in the specification and claims of this article and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of this article described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment. Example 1

[0025] This embodiment provides a water supply method with low water supply energy consumption, such as Figure 1 and Figure 2 As shown, the following steps are included: S100, energy consumption monitoring and early warning steps, such as Figure 2 As shown, including: S101. Install monitoring modules such as smart water meters and sensors at key nodes of the water supply system to monitor key parameters such as water flow, water pressure, and energy consumption in real time through the monitoring modules; these data provide a data basis for subsequent energy consumption analysis and scheduling; S102. Build an energy consumption data analysis platform to integrate, analyze and visualize the data collected above; use data analysis technology to identify peak energy consumption periods, inefficient operation areas, etc., and also provide data basis for subsequent optimization; S103, setting a monitoring threshold for each item of energy consumption data collected, and automatically triggering an early warning or alarm mechanism when the energy consumption data is abnormal or exceeds the preset monitoring threshold, to remind the management personnel so that timely processing measures can be taken; In this step, energy consumption monitoring technology is used to intelligently monitor various energy consumption data in the water supply system, intelligently analyze and process the energy consumption data, and automatically alarm according to the preset monitoring threshold, so as to timely control the abnormal energy consumption or excessive energy consumption.

[0026] S200, energy consumption scheduling steps, such as Figure 3 As shown, including: S201. Based on the energy consumption data monitored in real time, the intelligent scheduling algorithm is called to dynamically adjust the operating status of the pump station; the intelligent scheduling algorithm is used to reduce the operating power of the pump station and reduce energy consumption during the low-peak period of water demand; the intelligent scheduling algorithm is used to optimize the combination of pump stations during peak hours to ensure stable water supply and minimum energy consumption. For example, in the water supply system, fixed-speed pumps and variable-frequency pumps are installed at the same time; during peak hours, according to actual needs, an appropriate number of fixed-speed pumps are started to meet the basic water supply needs; at the same time, the variable-frequency pump is used to adjust the speed in real time according to the changes in the water supply pressure, so as to accurately control the water supply, ensure stable water supply and avoid excessive energy consumption; the fixed-speed pump operates stably and can continuously provide a stable water supply, while the variable-frequency pump has the ability to flexibly adjust the flow rate and can be adjusted in real time according to actual needs to reduce energy consumption; S202. According to the actual layout of the water supply network and user needs, the water supply area is divided into different pressure zones, and water is supplied separately according to the pressure zones; then, by adjusting the water supply pressure of each zone, water supply can be achieved on demand to avoid energy waste caused by over-pressure water supply. For example, according to the topography of the city, such as terrain height, slope changes, etc., the water supply area is divided into different pressure zones. Areas with higher terrain require higher water supply pressure, while areas with lower terrain can appropriately reduce the water supply pressure; considering the actual water demand of users, such as high-rise buildings, large residential areas, industrial areas, etc., these areas usually require higher water supply pressure, while ordinary residential areas, commercial areas, etc. can appropriately reduce the water supply pressure; specifically, set up high-pressure zone A: for users such as high-rise buildings, large residential areas and industrial areas, these areas require higher water supply pressure due to their high floors and large water consumption; in high-pressure zone A, by installing equipment such as booster pumps or variable frequency pumps, ensure The water supply pressure is stabilized within the range of 0.6~0.8MPa; at the same time, pressure reducing valves and pressure stabilizers are set in the pipe network to avoid problems such as pipe rupture and leakage caused by excessive water pressure; specifically, medium-pressure zone B is set: for users in ordinary residential areas, commercial areas, etc., the water demand in these areas is moderate, and the water supply pressure can be appropriately reduced; in medium-pressure zone B, the water supply pressure is controlled within the range of 0.4~0.6MPa by adjusting the opening of the water supply valve, changing the pipe diameter, etc.; this can not only meet the water demand of users, but also reduce energy consumption and reduce pipe wear; specifically, low-pressure zone C is set: for users in rural areas, small residential areas, etc., the water demand in these areas is relatively small, and the water supply pressure can be further reduced; in low-pressure zone C, the water supply pressure is controlled within the range of 0.2~0.4MPa through natural pressure or simple boosting equipment; this can not only meet the basic water demand of users, but also significantly reduce energy consumption and operating costs; S203, using energy storage equipment (such as energy storage tanks) to store electric energy during off-peak hours, and during peak hours, using the energy storage equipment to share the power supply required for the operation of the pump station, thereby saving some electric energy consumption; In this step, energy consumption scheduling technology is used to control the energy supply module in the water supply system to supply energy on demand, flexibly control the energy consumption of the pump station according to water demand, flexibly control the water supply pressure according to the water supply area, and recover energy according to the energy supply period. The recovered energy is used to share the energy consumption of the water supply system, further reducing the water supply energy consumption.

[0027] S300, pressure monitoring step, including: S301. Determine the pressure sensors at key locations of the water supply network and build a pressure sensor network, where the key locations include: the water source entrance, which is the starting point of the water supply network. The water quality, water quantity and pressure of the water source have an important impact on the entire network; therefore, the pressure sensor at the water source entrance can monitor the pressure changes of the water source in real time to ensure a stable supply of water; branch nodes, there are usually multiple branch nodes in the water supply network. The water flow direction, flow rate and pressure at these nodes will change. The pressure sensors at these nodes can monitor the pressure conditions of the branch nodes in real time, and promptly discover and solve possible problems; the user end is the end point of the water supply network and the location where users directly use water; the pressure sensor at the user end can monitor the pressure changes at the user end in real time to ensure that users can use water normally; terrain Changes: In the water supply network, changes in terrain will cause changes in water flow speed and pressure, especially in locations with higher or lower terrain, and locations with greater terrain changes. The pressure sensors can more significantly monitor pressure changes; Historical problem areas: If the water supply network has had problems in the past, such as leaks, bursts, etc., then these areas are potential problem areas. The pressure sensors in these areas can monitor pressure changes in real time to prevent similar problems from happening again; In summary, by analyzing pressure data, identifying bottlenecks and potential problem areas in the pipeline network, regularly maintaining and optimizing the pipeline network, and reducing energy consumption losses caused by pipeline aging, leakage, etc., for example: by real-time monitoring and analysis of pressure data, abnormal pressure in the pipeline network can be discovered in time. When the pressure at a certain location suddenly rises or falls, it is determined that there is a problem at that location; In this step, pressure monitoring technology is used to analyze problem areas in the water supply system to facilitate subsequent energy consumption optimization.

[0028] S400, comprehensive energy-saving processing steps, such as Figure 4 As shown, including: S401. Use high-efficiency and energy-saving pumps, motors and control systems to replace old equipment. Improve the energy efficiency of equipment and reduce energy consumption through technological upgrades; S402, periodically push water conservation information to the user end to strengthen the user end's water management and water conservation awareness; S403. Regularly conduct energy efficiency evaluation on the water supply system, and continuously adjust and optimize the energy consumption scheduling strategy in S200 based on the energy consumption evaluation results to ensure that the water supply system is always in an efficient operating state.

[0029] In summary, the comprehensive application of energy consumption monitoring technology, energy consumption scheduling technology and pressure monitoring technology can significantly improve the energy efficiency of the water supply system. This not only helps to reduce operating costs, but also promotes sustainable development and achieves a win-win situation in economic and environmental benefits.
