Description

Technical Field

[0001] This utility model belongs to the field of differentiated water supply, specifically relating to an integrated pipeline differentiated water supply system. Background Technology

[0002] As residents become more health-conscious, their demands for domestic water are becoming more refined and segmented. Ordinary tap water is sufficient for cleaning and washing, while water used for cooking, drinking, preparing beverages, ironing, and underfloor heating often requires drinking water with lower hardness and fewer ions. However, traditional municipal water supply systems use a single water quality standard, which cannot meet these diverse water demands.

[0003] Current differentiated water supply technology can significantly improve water resource utilization and alleviate supply-demand imbalances through differentiated treatment and transportation. However, existing differentiated water supply systems have some technical drawbacks: 1. Traditional centralized piped drinking water transportation modes mostly use a main water pressurization system plus secondary water supply equipment. In this mode, the original secondary pressurization equipment for tap water is unrelated to the water treatment equipment, and the two systems operate in isolation. The flushing concentrate produced by the water pressurization unit in the water treatment equipment is directly discharged, wasting resources. Furthermore, the secondary water supply equipment in the water treatment equipment treats and depressurizes the drinking water, then transports it back to users through pipelines, wasting energy. 2. Since drinking water accounts for only a very small portion of total domestic water consumption, the secondary water supply in the piped drinking water system... Secondary water supply equipment is much smaller than that used for domestic water supply. To save costs, most water supply companies use a single booster unit to pressurize drinking water, and then reduce the pressure at the user terminal using numerous pressure reducing valves in low- and medium-pressure areas. While this method saves on pipeline and equipment costs, it increases the load on the pipelines and raises the risk of pipeline bursts. 3. Traditional water treatment equipment mostly uses isolation and adsorption filter media for interception filtration, requiring regular replacement of the filter media. This not only greatly increases the consumption of filter media but also brings many maintenance troubles to users. Therefore, to solve the core problems of existing differentiated water supply systems, such as low integration, lack of concentrated water reuse, and insufficient zonal pressure stabilization, an integrated solution is urgently needed. Summary of the Invention

[0004] The purpose of this utility model is to overcome the problems of existing differentiated water supply systems and provide an integrated pipeline differentiated water supply system that integrates centralized water replenishment and pressurization, centralized deep water purification and zoned adaptive pressure stabilization to achieve stable and safe differentiated delivery of drinking water and domestic water in a region, minimize equipment and pipeline infrastructure costs, effectively reduce energy consumption and save resources.

[0009] The water purification equipment is located at the highest point of the entire system. The raw water pipeline of the adaptive secondary water supply equipment is connected to a domestic water supply pipeline, and the domestic water supply pipeline is connected to the purification pipeline of the water purification equipment. Multiple domestic water supply branch pipes are connected to the domestic water supply pipeline, and the domestic water supply branch pipes are connected to the domestic water supply terminals. The pressure stabilizing pipeline of the adaptive pressure stabilizing equipment is connected in series with the domestic water supply branch pipes. The flushing pipeline of the water purification equipment is connected to the flushing water return of the adaptive secondary water supply equipment. At the beginning of the pipe, the drinking water outlet pipe of the water purification equipment is connected to the drinking water supply pipe. The end of the drinking water supply pipe is connected to the drinking water return pipe of the water purification equipment. Multiple drinking water supply branch pipes are connected to the drinking water supply branch pipes. The drinking water supply branch pipes are connected to the drinking water users.

The raw water control cabinet of the adaptive secondary water supply equipment, the pressure stabilizing control cabinet of the adaptive pressure stabilizing equipment, and the purification control cabinet of the water purification equipment are connected to the central control cabinet.

[0010] Optionally, the regulating water tank of the adaptive secondary water supply equipment is equipped with a raw water discharge pipe and a raw water disinfection and sterilization device. The raw water discharge pipe is equipped with a raw water discharge valve, and an air filter is installed at the raw water vent on the regulating water tank.

[0013] Optionally, an air filter is provided at the air inlet of the one-way air inlet valve of the energy storage tank adapted to the voltage stabilizing equipment.

[0014] Optionally, the domestic water supply pipeline is connected to multiple direct-use branch pipes, which are connected to the direct-use water end.

[0015] The operation process of this utility model is as follows: the first end of the raw water pipeline of the adaptive secondary water supply equipment is connected to the municipal pipe network, the water purification equipment is placed at the highest point of the entire system (the highest vertical elevation), the concentrated water regulating valve of the water purification equipment is manually adjusted to set the ratio of concentrated water to pure water to meet the water production requirements, the energy storage tank of the adaptive pressure stabilizing equipment is placed at a high position in its respective water use zone, the control cabinet data of all equipment enters the central control cabinet, the central control cabinet uniformly allocates the start and stop of the equipment, monitors the operating conditions, issues an alarm signal in case of failure, and takes corresponding control measures;

[0016] First, tap water from the municipal water supply network enters the raw water pipeline of the adaptive secondary water supply equipment. The control cabinet, based on real-time data from raw water pressure sensor I, raw water pressure sensor II, and raw water level sensor, and comparing this data with preset parameters, controls the opening and closing of the raw water inlet valve and bypass valve, as well as the startup of raw water booster pump group I and raw water booster pump group II. The system prioritizes using flushing return water as a replenishment measure for the regulating water tank. When the water level in the regulating water tank falls below the set low-level guaranteed water usage threshold (not meeting normal water usage needs), and the tap water pressure is sufficient (greater than the preset value), the raw water inlet valve and bypass valve open, and the raw water booster pump group II starts. A portion of the tap water is injected into the regulating water tank for standby, replenishing the regulating water tank to the preset receiving level (with reserved space for storing flushing return water). The raw water inlet valve then closes. One portion of the tap water is pressurized by the raw water booster pump group II before entering the domestic water supply pipeline. When the tap water pressure is low during peak water usage (within the preset range), the raw water inlet valve is closed, the bypass valve is opened, and the raw water booster pump group II is started. All the tap water is pressurized by the raw water booster pump group II before entering the domestic water supply pipeline. When the tap water pressure is insufficient to meet normal usage during peak water usage (below the preset value), the raw water inlet valve is opened, the bypass valve is closed, and the raw water booster pump group I and the raw water booster pump group II are started. The tap water in the regulating tank is pressurized by the raw water booster pump group I and the raw water booster pump group II before entering the domestic water supply pipeline. Through the above water replenishment and pressure replenishment methods, the adaptive secondary water supply equipment provides the domestic water supply pipeline with tap water that meets the conditions.

[0017] Next, the tap water entering the domestic water supply pipeline is distributed to each domestic water supply branch pipe, and after passing through the adaptive pressure stabilizing device, it is supplied to the domestic water end. The control cabinet, based on real-time data provided by pressure stabilizing sensor I, pressure stabilizing sensor II, and pressure stabilizing liquid level sensor, and comparing with preset parameters, controls the opening and closing of the pressure stabilizing inlet valve and pressure stabilizing outlet valve, as well as the adjustment of the upstream pressure. When the pressure inside the tank is lower than the preset lower pressure limit, the pressure stabilizing inlet valve and pressure stabilizing outlet valve open, and the pressurized tap water enters the tank. As the pressure inside the tank gradually reaches the preset upper pressure limit, the pressure stabilizing inlet valve closes, and the energy storage tank supplies domestic water. The tank provides tap water at a suitable pressure. As the air inside the tank is repeatedly compressed, some air mixes with the water and is discharged along with the water, resulting in a reduction in the amount of air inside the tank. This causes a decrease in the regulating capacity of the energy storage tank, which manifests as an abnormal rise in the liquid level. When the pressure stabilizing liquid level sensor detects that the liquid level inside the tank has reached the preset upper limit, the pressure stabilizing water inlet valve closes and the pressure stabilizing water outlet valve opens, and the water inside the tank is continuously discharged, causing the liquid level inside the tank to drop. When the air pressure outside the tank is greater than the air pressure inside the tank, air enters the tank through the one-way air inlet valve. When the liquid level inside the tank reaches the preset lower limit, the pressure stabilizing water inlet valve opens, and the tank is replenished with water and pressure normally.

[0018] Then, tap water from the domestic water supply pipeline enters the purification pipeline of the water purification equipment. The control cabinet, based on real-time data from various precision inlet pressure sensors, online water quality monitors, and purification level sensors, controls the opening and closing of the purification inlet valve, high-pressure inlet valve, water tank inlet valve, abnormal drainage valve, and various precision flushing valves, as well as the start and stop of the purification booster pump. During normal water production, the purification inlet valve, high-pressure inlet valve, and water tank inlet valve are open, all flushing valves and abnormal drainage valves are closed, the purification booster pump is started, and the tap water, filtered through various precision filter components, forms drinking water that flows through the online water quality monitoring system. The device enters the water storage tank. When the water level sensor detects that the water level in the tank has reached the preset high or low level, it controls the opening and closing of the purification inlet valve, high-pressure inlet valve, and water tank inlet valve, as well as the start and stop of the booster pump. This adjusts the water purification process to maintain a certain amount of drinking water in the storage tank. Since the entire water purification equipment is located at the highest point of the system, it only needs to rely on gravity to pressurize the water supply. The drinking water in the storage tank flows into the drinking water outlet pipe and is pressurized by the circulation pump group (normally running, only needing to provide pressure to achieve pipeline circulation and pressure supplementation at the high-area water end) before flowing into the drinking water supply pipeline. The drinking water flowing back from the water pipes is disinfected and sterilized by the purification and disinfection device (normally running) before flowing back into the storage tank. When the low-precision inlet pressure sensor detects a pressure greater than that detected by the medium-precision inlet pressure sensor, or the medium-precision inlet pressure sensor detects a pressure greater than that detected by the high-precision inlet pressure sensor, and the difference reaches a set value, the high-pressure inlet valve closes, the purification booster pump stops, and the low-precision or medium-precision flushing valve opens, allowing water from the front end to flush the low-precision or medium-precision filter components. The forced flushing valve is normally closed during water production. In the normal operation mode, when water is not being produced (water tank inlet valve closed) or the equipment has just started (inlet valve switched from closed to open), the forced flushing valve opens, and a large flow of water from the front end flushes the high-precision filter membrane assembly. After flushing for a period of time, the forced flushing valve closes. The above flushing operation can also be performed actively by setting the flushing duration and flushing start time through the control cabinet. The flushing water flows into the flushing pipeline through various flushing valves. When the online water quality monitor detects abnormal water quality parameters, the abnormal drain valve opens, the water tank inlet valve closes, and unqualified water flows into the flushing pipeline. The control cabinet issues an alarm to alert the operation and maintenance personnel that the water production is abnormal.

[0019] Finally, the drinking water is distributed to each drinking water supply branch pipe through the drinking water supply pipeline, and then supplied to the drinking water user after passing through the adaptive pressure stabilizing equipment.

[0020] The principle of this invention: The flushing concentrate from the purification equipment is returned to the regulating water tank via the flushing pipeline for closed-loop recycling and reused for domestic water, achieving zero discharge of flushing water and saving water; the water purification equipment is placed at the highest point of the system, using gravity to supply drinking water to the high zone, while only supplementing and pressurizing the low zone, saving energy; each zone dynamically adjusts the pressure through an adaptive pressure stabilizing device, replacing the mechanical pressure reducing valve and reducing the risk of pipe bursts; during peak water usage and tap water outages, the water stored in the regulating water tank of the adaptive secondary water supply equipment can meet the peak water replenishment and regulation needs, as well as provide emergency water supply, making the water supply more stable; the "multi-stage filtration + online water quality monitoring instrument + abnormal drainage valve" and the circulating disinfection and sterilization device ensure the quality of drinking water, while automatic flushing extends the service life of the filter media, ensuring long-term operation of the water purification system; through integrated management (secondary water supply + purification + pressure stabilization), the secondary water supply, purification, and pressure stabilization equipment are linked by a central control cabinet to achieve efficient and coordinated management of domestic water and drinking water.

[0021] Compared with the prior art, this utility model has at least the following beneficial effects: This utility model integrates centralized water replenishment and pressurization, centralized deep water purification and zoned adaptive pressure stabilization, and realizes stable and safe differentiated transportation of drinking water and domestic water in the area, minimizing the cost of equipment and pipeline infrastructure, effectively reducing energy consumption and saving resources.
