Installation site of vacuum flushing equipment for Baoding storage tankThe installation and commissioning project of vacuum flushing equipment for storage tanks in Qingyuan District, Baoding, Hebei Province is one of the key projects for upgrading and renovating urban drainage systems in recent years, aiming to improve the operational efficiency and environmental performance of storage tanks through vacuum flushing technology. This project design adopts remote vacuum secondary flushing function, which achieves efficient and energy-saving flushing operation through intelligent control, providing new technical support for urban water environment governance.

1、 Background and Requirements Analysis: As an important urban area of Baoding City, Qingyuan District is facing enormous pressure on its drainage system with the acceleration of urbanization. The traditional flushing method of storage tanks has problems such as water resource waste and unstable flushing effect, which are difficult to meet modern environmental protection requirements. To this end, the water department of Qingyuan District proposed the use of vacuum flushing technology, which achieves efficient flushing through the principle of negative pressure suction while reducing water consumption. This project requires the equipment to have remote control function to adapt to the development trend of smart water management, and to ensure the cleaning of sediment at the bottom of the pool through a secondary flushing design.

2、 Technical characteristics of vacuum flushing equipment 1 Integrated PLC control system for remote control and automation equipment, supporting remote operation and real-time monitoring. Operations personnel can start the flushing program through the central control platform or mobile terminal, and adjust the flushing parameters based on sensor feedback to achieve precise operations. 2. Vacuum secondary flushing technology uses negative pressure to quickly suction surface pollutants, while secondary flushing targets stubborn sediments at the bottom of the pool, using a mixture of high-pressure airflow and water flow to ensure cleanliness. This technology saves more than 30% water compared to traditional water flushing. 3. Energy saving and environmentally friendly design equipment adopts low-power vacuum pumps and circulating water utilization systems to reduce energy consumption; At the same time, the closed flushing process avoids splashing of sewage, reduces the spread of odors, and meets green construction standards.

3、 The key link of installation and debugging is 1Installation site of vacuum flushing equipment for Baoding storage tank Equipment installation foundation construction: Customize steel brackets according to the structure of the storage tank to ensure the horizontal stability of the equipment; The vacuum pipeline is made of corrosion-resistant stainless steel material, and the interface is sealed. Electrical connection: The control system is connected to the existing PLC network of the storage tank to complete signal transmission testing and ensure that remote command response is not delayed. 2. System debugging and single machine testing: Start the core components such as vacuum pump and solenoid valve in sequence, and check whether the negative pressure value meets the design standard (-0.08MPa to -0.1MPa). Linkage debugging: Simulate actual working conditions, verify the timing control and effect of secondary flushing, observe the cleanliness of the pool bottom through a camera, and optimize the flushing cycle. Remote functional verification: Test the stability of 4G/fiber optic communication to ensure that fault alarms (such as pipeline blockage) can be pushed to the operation and maintenance end in real time.

4、 Challenges and Solutions in Project Implementation 1 During the initial trial operation of pipeline airtightness, it was found that there was air leakage in some parts of the pipeline, resulting in insufficient negative pressure. Locate the leak point using a helium leak detector, replace the sealing ring, and increase the torque of the flange bolts to solve the problem. 2. Compatibility with old systems. The original storage tank lacks sensor interfaces, and rewiring is required when adding level gauges and turbidity meters. The project team uses wireless transmission modules to reduce the amount of renovation work and achieves data interoperability through software protocol conversion.

5、 Project benefits and promotional value 1 After the commissioning of operation effect, the flushing period of the storage tank is extended from 7 days to 15 days, with an average annual water saving of about 12000 tons; The residual sludge at the bottom of the pool has been reduced by 80%, significantly reducing the frequency of manual dredging. 2. Industry demonstration significance: This case provides a reusable technical solution for the renovation of storage tanks in small and medium-sized cities, and its remote control mode is particularly suitable for areas with scattered drainage facilities. In 2025, the Department of Housing and Urban Rural Development of Hebei Province has included it in the "Catalogue for Promoting Energy saving Technologies in Urban Drainage Systems".

6、 In the future, Qingyuan District plans to deeply integrate vacuum flushing equipment with smart water management platforms, introduce AI algorithms to predict sludge accumulation trends, and further optimize flushing strategies. At the same time, explore the feasibility of photovoltaic driven vacuum pumps and promote zero carbon operation throughout the entire process.
