Description

Technical Field

[0001] This utility model relates to the field of water supply system technology, and in particular to a desulfurization industrial water supply system with a pressurization structure. Background Technology

[0002] In industrial desulfurization processes, the industrial water supply system is a core component, requiring a continuous supply of industrial water with stable pressure and flow rate. This is necessary to ensure the atomization effect of the desulfurization tower spray device through stable pressure, guaranteeing sufficient gas-liquid reaction for efficient desulfurization. Furthermore, precise flow control is needed to remove reaction heat, maintain a stable tower outlet temperature, and prevent equipment corrosion or efficiency degradation.

[0003] Existing systems generally rely directly on the factory's industrial water supply network without an independent regulating unit. Since the network needs to meet the water demand of multiple units simultaneously, pressure fluctuations can easily occur when other units start or stop, load changes, or the network is under maintenance. Furthermore, when the desulfurization reaction requires a sudden increase in water supply (such as when the spray system restarts or the sulfur content in the flue gas suddenly increases), the instantaneous flow rate of the network is insufficient, which directly leads to the water replenishment rate lagging behind the reaction demand.

[0004] This will not only reduce desulfurization efficiency and increase the risk of excessive emissions, but may also cause scaling and blockage in the tower due to unstable atomization, shortening the equipment life. At the same time, temperature fluctuations will also affect the stability of subsequent denitrification and dust removal processes, ultimately increasing the system's energy consumption and maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide a desulfurization industrial water supply system with a pressurization structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A desulfurization industrial water supply system with a pressurization structure includes a water supply tank, a second main delivery pipe on one side of the water supply tank, a first main delivery pipe on the other side of the second main delivery pipe, the other end of the first main delivery pipe being connected to a water supply pipeline, a makeup water pipe on the first main delivery pipe, the other end of the makeup water pipe being connected to the water supply tank, a booster pump on the makeup water pipe, and a shut-off valve on the second main delivery pipe.

[0007] As a preferred embodiment of this utility model, a small hydraulic turbine generator is installed on the first main delivery pipe, and a power module is installed between the second main delivery pipe and the water supply pipe, with the small hydraulic turbine generator connected to the power module.

[0008] As a preferred embodiment of this utility model, a water pressure sensor is provided on the second main conveying pipe, and a pair of fixed seats are provided on the top of the second main conveying pipe. A control module and an alarm light are respectively provided on the two fixed seats. The water pressure sensor is connected to the control module, and the control module is connected to the alarm light.

[0009] In a preferred embodiment of this invention, the water pressure sensor, control module, alarm light, and shut-off valve are all electrically connected to the power supply module.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1. This utility model sets up a main water inlet + booster water supply dual channel. When the pipeline pressure is insufficient, the staff can manually close the shut-off valve and start the booster pump according to the alarm light prompt. The booster pump will pressurize and replenish water to the water tank through the water supply pipe to ensure that the water tank has sufficient water supply and stable pressure. This provides continuous guarantee for the spray atomization and outlet temperature control of the desulfurization tower and avoids water supply problems from affecting the desulfurization efficiency.

[0011] 2. This utility model uses a small hydraulic turbine generator on the main delivery pipe to generate electricity in real time using the kinetic energy of the industrial water flow in the pipe. The electrical energy is stored in the power module and used to power the water pressure sensor, control module, alarm lights, etc. There is no need to connect to an external power source to support the monitoring and alarm system. This realizes the secondary utilization of water resources kinetic energy, reduces energy waste, and can significantly reduce the energy consumption cost of the desulfurization water supply system and improve energy utilization efficiency in the long run.

[0012] This utility model uses a water pressure sensor in the second main delivery pipe to collect the inlet water pressure in real time. When the pressure is abnormal, the control module quickly triggers the alarm light to indicate the water supply status, allowing staff to keep abreast of the water supply status. The alarm prompt + manual operation valve pump mode has a clear logic and clear steps, allowing staff to respond quickly without complicated training. This avoids the risks of pipeline damage and water tank overflow caused by abnormal pressure, and improves the safety of system operation and the convenience of maintenance.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figures 1-2 As shown, the present invention proposes a desulfurization industrial water supply system with a pressurization structure, which includes a water supply pipeline that first delivers water to a main delivery pipe 2, the other end of which is connected to a main delivery pipe 20, and the end of the main delivery pipe 20 is connected to the inlet of the water supply tank 1, forming a real-time main water supply channel of water supply pipeline - main delivery pipe 2 - main delivery pipe 20 - water supply tank 1, ensuring that industrial water is stably delivered to the water supply tank 1 for storage, and providing a reserve for the desulfurization reaction water supply; One end of the water supply pipe 3 is connected to the main delivery pipe 2, and the other end is connected back to the water supply tank 1. The booster pump 5 on the water supply pipe 3 is on standby in real time. When the pressure of the water supply network fluctuates or the main channel lags in the water supply to the tank, the booster pump 5 will start immediately to pressurize the industrial water and deliver it to the tank, supplementing the inlet flow and pressure, and ensuring the water tank inlet efficiency. The small hydraulic turbine generator 6 on the main delivery pipe 1 2 generates electricity in real time by utilizing the kinetic energy of the industrial water flow in the pipe. It is connected to the power module 60 between the main delivery pipe 2 20 and the water supply pipe 3 through a wire. The electrical energy is stored in the power module 60 in real time to provide continuous power to electrical components such as the water pressure sensor 7, the control module 71, and the alarm light 72. The water pressure sensor 7 on the main delivery pipe 20 collects the inlet water pressure data in real time and transmits the data to the control module 71 on the top mounting base 70 of the main delivery pipe 20 via a signal line. The control module 71 is connected to the alarm light 72 and both are powered by the power module 60 in real time via wires. When the water pressure sensor 7 detects an abnormal pressure, the data is fed back to the control module 71 in real time, and the control module 71 immediately triggers the alarm light 72 to light up, alerting the staff with a light signal. After seeing the alarm, the staff manually operates the shut-off valve 4 on the main delivery pipe 20. By closing the shut-off valve 4, the booster pump 5 is turned on to ensure stable water intake to the water tank.
