Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pH regulation of circulating cooling water, and in particular to a system for monitoring pH of circulating cooling water and automatically dosing a pH regulator. Background Art
[0002] In chemical production processes, circulating cooling water systems are crucial for maintaining stable production operations. They not only fulfill the core function of cooling and reducing temperatures, but also significantly improve energy efficiency through waste heat recovery. However, circulating cooling water systems are highly susceptible to water contamination, with pH, a key water quality indicator, having a decisive impact on system operational safety. Excessively high pH values can easily lead to scale deposition and reduce heat exchange efficiency, while excessively low pH values can accelerate corrosion of metal equipment, threatening system safety.
[0003] Currently, the pH monitoring and automatic dosing of regulators in the chemical industry's circulating cooling water systems still face many bottlenecks. On the one hand, the traditional monitoring method of manual sampling combined with laboratory analysis is not only time-consuming and labor-intensive, but also difficult to achieve real-time monitoring and unable to capture water quality changes in a timely manner. On the other hand, although some companies have introduced automatic monitoring equipment, they generally suffer from large deviations in monitoring data, slow response to regulator addition, or excessive addition of regulators. These problems not only increase the company's operating costs, but also lead to pH control failure due to unstable reagent addition, which in turn causes abnormal system fluctuations and even equipment shutdowns. More seriously, pH loss of control may also lead to environmental pollution risks, burying hidden safety accidents, and posing a dual threat to the company's production and ecological environment.

[0032] The present application provides a circulating cooling water pH monitoring and pH regulator automatic dosing system, including a regulator storage unit 1, a regulator replenishment unit 2, a regulator dosing unit 3, a circulating cooling water monitoring linkage unit 4, and a regulator discharge unit 5. Among them, the regulator storage unit 1 is used to store the pH regulator; the regulator replenishment unit 2 is connected to the regulator storage unit 1 and is used to input the pH regulator into the regulator storage unit 1; the regulator dosing unit 3 is connected to the regulator storage unit 1 and the existing circulating cooling water system, and the regulator dosing unit 3 is used to put the pH regulator stored in the regulator storage unit 1 into the existing circulating cooling water system; the circulating cooling water monitoring linkage unit 4 is used to monitor the pH value of the circulating cooling water in the existing circulating cooling water system and control the regulator dosing unit 3 to put the pH regulator into the existing circulating cooling water system according to the pH value of the circulating cooling water; the regulator discharge unit 5 is connected to the regulator storage unit 1, and the regulator discharge unit 5 is used to discharge the pH regulator stored in the regulator storage unit 1. Through the cooperation of the circulating cooling water monitoring linkage unit 4 and the regulator dosing unit 3, the real-time monitoring and adjustment of the pH value of the circulating cooling water can be realized. By comparing the monitored pH value with the preset standard value and accurately calculating the dosing amount, the system can achieve precise control of the pH value, the monitoring data is accurate, which helps to strictly maintain the pH value of the circulating cooling water within the ideal range, effectively reduce the problems of scale formation and equipment corrosion. The entire system forms a closed-loop control system through the coordinated work of each unit, can timely detect and solve the problem of abnormal pH value of the circulating cooling water, ensures the stable operation of the circulating cooling water system, reduces system failures and downtime caused by pH value fluctuations, and avoids the threat to enterprise production and the ecological environment caused by the out-of-control pH value of the circulating cooling water.
[0033] The regulator storage unit 1 includes a regulator storage tank 11, a drying pipeline 12, a drying ball valve 13, and a storage tank dryer 14. One end of the drying pipeline 12 is connected to the top exhaust port of the regulator storage tank 11. The drying ball valve 13 and the storage tank dryer 14 are arranged on the drying pipeline 12 in sequence along the exhaust direction. Specifically, the model of the storage tank dryer 14 is CAS-30. During the use of the pH regulator in the regulator storage tank 11, the liquid level will change. When the liquid level drops, the pressure in the tank decreases, and external air needs to enter the storage tank to balance the pressure. When the liquid level rises or the pressure increases due to the temperature change in the tank, the gas in the tank needs to be discharged. The drying pipeline 12, as the channel connecting the top exhaust port of the regulator storage tank 11 to the outside, provides a path for the gas to enter and exit. When the drying ball valve 13 is in the open state, it allows the gas to pass through the drying pipeline 12. The storage tank dryer 14 arranged on the drying pipeline 12 along the exhaust direction will dry the air entering and exiting the storage tank. When external air enters, the storage tank dryer 14 will adsorb the moisture in it to prevent the wet air from entering the storage tank and causing the pH regulator to get damp. When the gas in the tank is discharged, it will also pass through the dryer to avoid the moisture in the tank from condensing in the pipeline during the exhaust process and affecting the normal operation of the system. Through the setting of the drying pipeline 12 and the storage tank dryer 14, it effectively prevents the external moisture from entering the regulator storage tank 11, prevents the pH regulator from deteriorating or changing in concentration due to dampness, ensures the quality and performance stability of the regulator, and further ensures the accuracy and effectiveness of the pH adjustment of the circulating cooling water.
[0034] The regulator replenishment unit 2 includes a regulator replenishment pipe 21, a first Y-type filter 22, and a truck unloading pump 23. One end of the regulator replenishment pipe 21 is connected to the feed port of the regulator storage tank 11. The first Y-type filter 22 and the truck unloading pump 23 are arranged on the regulator replenishment pipe 21 in sequence along the direction in which the regulator flows into the regulator storage tank 11. When replenishing the pH regulator into the regulator storage tank 11, the end of the regulator replenishment pipe 21 away from the regulator storage tank 11 is connected to a tank truck through a quick connector, and the truck unloading pump 23 is used to transport the pH regulator in the tank truck into the regulator storage tank 11. Among them, the pH regulator is concentrated sulfuric acid. The first Y-type filter 22 can effectively filter out the impurities in the pH regulator, avoid the impurities from mixing into the regulator storage tank 11, prevent the impurities from affecting the performance of the pH regulator, ensure the quality of the pH regulator, and further ensure the accuracy and effectiveness of the pH adjustment of the circulating cooling water.
[0035] A first check valve 6 is provided on the regulator replenishment pipe 21 between the truck unloading pump 23 and the regulator storage tank 11. The reverse flow of the fluid may cause the impeller of the truck unloading pump 23 to reverse, which may damage the mechanical seal, bearings and other components of the truck unloading pump 23. The existence of the check valve avoids this situation and prolongs the service life of the truck unloading pump 23.
[0036] The regulator dosing unit 3 includes a regulator dosing pipe 31, a first pneumatic cut-off ball valve 32, a first bypass pipe 33 and two regulator pumping assemblies 34. The first bypass pipe 33 and the two regulator pumping assemblies 34 are arranged in parallel on the regulator dosing pipe 31. One end of the regulator dosing pipe 31 is connected to the discharge port of the regulator storage tank 11, and the other end of the regulator dosing pipe 31 is connected to the pool in the existing circulating cooling water system. The first pneumatic cut-off ball valve 32 is arranged on the first bypass pipe 33. A second pneumatic cut-off ball valve 14 is provided on the regulator dosing pipe 31. The second pneumatic cut-off ball valve 14 is arranged in series with one of the regulator pumping assemblies 34. The second pneumatic cut-off ball valve 14 is located on the regulator dosing pipe 31 between the regulator pumping assembly 34 and the existing circulating cooling water system. Among them, the two regulator pumping assemblies 34 are arranged in parallel with the first bypass pipe 33 to form three flow adjustment modes: Double-pump mode: The two pumping assemblies operate simultaneously, the second pneumatic cut-off ball valve 14 is opened, and the first pneumatic cut-off ball valve 32 is closed. At this time, all the flow enters the circulating water tank through the regulator pumping assembly 34, which is suitable for scenarios where the pH value needs to be adjusted quickly (such as when the pH value deviates significantly from the target value); Single-pump mode: Only one regulator pumping assembly 34 is enabled, and the other is opened through the second pneumatic cut-off ball valve 14, and the first pneumatic cut-off ball valve 32 is still closed, which is suitable for medium adjustment requirements and reduces energy consumption and equipment wear; Bypass dilution mode: Neither of the two pumping assemblies is enabled. The first pneumatic cut-off ball valve 32 and the second pneumatic cut-off ball valve 14 are opened simultaneously. The regulator flows into the pool by gravity or the pressure of the storage tank through the bypass pipe to achieve small-dose fine adjustment. By switching between the three working modes, the system can cover a wide range of flow regulation from tiny flow to maximum flow to meet the pH control requirements under different working conditions.
[0037] The regulator pumping assembly 34 includes a second Y-type filter 341, a metering delivery pump 342, a second check valve 343 and a second bypass pipe 344. The second Y-type filter 341, the metering delivery pump 342 and the second check valve 343 are arranged in sequence along the PH regulator delivery direction. The second bypass pipe 344 is arranged in parallel with the metering delivery pump 342. A bypass valve 7 is provided on the second bypass pipe 344. When the system pressure is too high, the bypass valve 7 can be partially opened to release the excess pressure and protect the pump and pipeline from overpressure damage. The second Y-type filter 341 reduces the wear of impurities on the metering delivery pump 342 and extends the maintenance period and service life of the metering delivery pump 342.
[0038] A pressure regulating pipe 8 is connected to the regulator dosing pipe 31 between the second Y-type filter 341 and the metering and conveying pump 342. A pressure regulating valve 9 and a pulsation damper 10 are successively arranged on the pressure regulating pipe 8. When the metering and conveying pump 342 is working, due to its working mode, pulsations of flow rate and pressure will be generated. By opening the pressure regulating valve 9, part of the PH regulator enters the pulsation damper 10 through the pressure regulating pipe 8, making the flow of the PH regulator become stable and ensuring the stability of the PH regulator dosing.
[0039] The circulating cooling water monitoring linkage unit 4 includes a controller 41 and a PH detector. The PH detector is arranged on the water supply pipe in the existing circulating cooling water system. The PH detector is electrically connected to the controller 41, and the controller 41 is electrically connected to the metering and conveying pump 342. The PH detector monitors the PH value of the cooling water in the water supply pipe of the circulating cooling water system in real time, and converts the detected PH value signal into an electrical signal. The PH detector transmits the electrical signal to the controller 41. The controller 41 analyzes and processes the received signal, compares it with the preset PH value range. If the detected PH value deviates from the preset range, the controller 41 will send a corresponding control signal to the metering and conveying pump 342 according to the magnitude and direction of the deviation. The metering and conveying pump 342 adjusts its operating state according to the received signal, such as changing the rotation speed or stroke, so as to adjust the amount of the regulator conveyed into the circulating cooling water system, and adjust the PH value of the circulating cooling water to the preset appropriate range. By monitoring in real time and adjusting the dosing amount of the regulator in a timely manner, the PH value of the circulating cooling water can always be kept within the appropriate range, which helps to improve the stability and reliability of the circulating cooling water system and reduce problems such as equipment corrosion and scale formation caused by PH value fluctuations.
[0040] A magnetic flap level gauge 11 is installed on the regulator storage tank 11. The circulating cooling water monitoring and linkage unit 4 further includes a liquid level alarm 12. The liquid level alarm 12 is arranged on the regulator storage tank 11 and is electrically connected to the controller 41. The controller 41 is electrically connected to the unloading pump 23. Among them, the magnetic flap level gauge 11 is used to monitor the liquid level height in the regulator storage tank 11 in real time and display the liquid level information in an intuitive manner. The liquid level alarm 12 monitors the liquid level situation according to the set liquid level thresholds (such as the lowest liquid level threshold and the highest liquid level threshold). When the liquid level reaches or exceeds the set threshold, the liquid level alarm 12 will send a corresponding electrical signal to the controller 41 to inform the controller 41 that the liquid level is abnormal. After receiving the signal from the liquid level alarm 12, the controller 41 will control the operating state of the unloading pump 23 according to the type of the signal (such as a low liquid level signal or a high liquid level signal). If it is a low liquid level signal, the controller 41 will issue an instruction to start the unloading pump 23 to transport the pH regulator from the tank truck to the regulator storage tank 11 to supplement the pH regulator. If it is a high liquid level signal, the controller 41 may issue an instruction to stop the unloading pump 23 to prevent the regulator storage tank 11 from overflowing. By monitoring and controlling the liquid level of the regulator storage tank 11, the liquid level is always kept within a safe and appropriate range, avoiding the overflow risk caused by too high a liquid level and the impact on the normal supply of the pH regulator in the circulating cooling water system due to too low a liquid level, and ensuring the stable operation of the circulating cooling water system.
[0041] The regulator discharge unit 5 includes a first discharge branch pipe 51, a second discharge branch pipe 52, a discharge main pipe 53 and a trench 54. One end of the first discharge branch pipe 51 and one end of the second discharge branch pipe 52 are respectively connected to the discharge ports at the bottom of the regulator storage tank 11. The other ends of the first discharge branch pipe 51 and the second discharge branch pipe 52 are both connected to the discharge main pipe 53. The discharge main pipe 53 is connected to the trench 54. Discharge valves 13 are provided on both the first discharge branch pipe 51 and the second discharge branch pipe 52. When it is necessary to empty, clean the regulator storage tank 11 or discharge the pH regulator for other reasons, by opening the discharge valve 13 on the first discharge branch pipe 51 or the second discharge branch pipe 52 (or both discharge valves 13 can be opened simultaneously), under the action of gravity, the regulator flows out from the discharge ports at the bottom of the regulator storage tank 11 and enters the first discharge branch pipe 51 and the second discharge branch pipe 52 respectively. The regulators flowing out of the first discharge branch pipe 51 and the second discharge branch pipe 52 converge at the discharge main pipe 53 and are then transported to the trench 54 through the discharge main pipe 53. The trench 54 guides the regulator to a designated treatment location or collection facility to achieve the safe discharge or subsequent treatment of the regulator. The double discharge branch pipe design provides a certain degree of redundancy. If one of the discharge branch pipes is blocked, the discharge valve 13 fails or other problems occur, the discharge can be carried out through the other branch pipe to ensure that the regulator can be discharged smoothly, improving the reliability and stability of the system.
